Next, the operation of the first waste disposal apparatus 1 will be described.
First, the first lid 60 is set in the upright state, the input port is opened, and the waste D is input into the input section 10. Based on the fact that the first lid 60 is in the upright state, the control unit starts the operation of the suction unit 80A and the blower unit 80C of the deodorization device 80. Next, the first lid 60 is placed in the lying state, the input port of the input unit 10 is closed, and the operation unit (not shown) is operated to operate the waste disposal apparatus 1.

The waste disposal apparatus 1 first operates at least one of the first solenoid valve 14C and the second solenoid valve 14D by the control unit to discharge at least one of the first predetermined amount of water and hot water from the discharge unit 14. It is supplied to the crushing unit 20. Thus, the filth D and at least one of water and hot water are put into the crushing unit 20. At this time, the first on-off valve 12 is in a closed state. The motor 20G of the crushing unit 20 is not driven when the control unit determines that the first lid 60 has at least one of the state in which the inlet is opened and the state in which the disintegrant is not charged. It is controlled by the control unit.

(4) When the control unit determines that the first lid 60 is in the state in which the inlet is closed and the state in which the decomposing agent is charged, the motor 20G of the crushing unit 20 is driven, and the waste D is crushed. At this time, the control unit estimates the amount of the input waste D based on the magnitude of the first load of the motor 20G. Specifically, the control unit detects the first load (that is, the power consumption of the motor 20G) related to the crushing unit 20 and crushes the waste D when the first load exceeds a predetermined value. Then, the amount of the waste D is estimated based on the time when the first load exceeds the predetermined value. The filth D is crushed in the crushing unit 20 to become the crushed material C. The control unit operates the decomposing agent introducing device 13 based on the signal corresponding to the magnitude of the first load, and injects a predetermined amount of the decomposing agent into the chute 21. A predetermined amount of the decomposing agent supplied to the chute 21 flows into the mixer 70.

Next, in the mixer 70, the crushed material C, at least one of the first predetermined amount of water and hot water, and the predetermined amount of the decomposing agent are stirred, and the polymer having absorbed and retained the water and the decomposing agent are mixed. The reaction is allowed to take out the water absorbed and retained by the polymer. In this way, in the mixer 70, the crushed material C, at least one of water and hot water, and a predetermined amount of the decomposing agent are stirred to form the stirred material S.

At this time, the controller detects the second load related to the motor 70A of the mixer 70. Specifically, the magnitude of the second load detected at this time is the magnitude of the current consumption of the motor 70A.

If the control unit determines that the magnitude of the second load of the motor 70A is not less than or equal to the predetermined value even after the predetermined time has elapsed (that is, the reaction between the polymer of the agitated material S and the decomposer has not sufficiently proceeded), The disintegrating agent injecting device 13 is controlled so that an agent is additionally injected from the injecting agent injecting device 13. At this time, the motor 70A is continuously driven, and the mixer 70 can further promote the reaction between the polymer of the agitated substance S and the decomposing agent. Thus, in the mixer 70, the crushed material C, at least one of the first predetermined amount of water and hot water, and the decomposing agent are agitated, and the crushed material C is converted into the agitated material S. The reaction with can be further advanced.

Next, when the control unit determines that the magnitude of the current consumption of the motor 70A (that is, the magnitude of the second load) is equal to or smaller than a predetermined value, the first on-off valve 12 in the closed state is opened by the control unit. To be. Then, the agitated material S flows into the dilution tank 30 via the discharge path 11.

At this time, the first electromagnetic valve 14C and the second electromagnetic valve 14D of the discharge unit 14 are operated by the control unit to supply at least one of the second predetermined amount of water and hot water from the discharge unit 14 to the crushing unit 20. At least one of the second predetermined amount of water and hot water is a predetermined amount with respect to the amount of the stirring object S. At this time, the motor 20G of the crushing unit 20 and the motor 70A of the mixer 70 are being driven. Thus, the inside of the crushing unit 20 and the inside of the mixer 70 can be washed while the stirred material S in the mixer 70 is surely conveyed into the dilution tank 30. The first ventilation path 17 suppresses the inside of the dilution tank 30 from becoming a positive pressure when at least one of the crushed material C and the second predetermined amount of water and hot water flows into the dilution tank 30. If at least one of the water and the hot water overflows from the crushing unit 20 when at least one of the second predetermined amount of the water and the hot water is supplied from the discharge unit 14, the second predetermined amount is supplied through the first ventilation path 17. 2 A part of at least one of the predetermined amount of water and hot water flows into the dilution tank 30. The second on-off valve 16 is in a closed state when at least one of the second predetermined amount of water and hot water and the agitated material S flow into the dilution tank 30.

Next, at least one of the second predetermined amount of water and hot water and the stirred material S are diluted in the dilution tank 30 to make the stirred material S a diluted material T. At this time, the second on-off valve 16 is in a closed state. First, the drive of the motor 30A of the dilution tank 30 is started by the control unit. As a result, the propeller (not shown) of the dilution tank 30 rotates, and the second predetermined amount of at least one of water and hot water and the agitated material S are agitated. Become. Accordingly, the concentration of Ca (calcium) or Cl (chlorine) of the decomposing agent contained in the agitated material S in the agitated material S can be reduced by using the diluent T, and the Ca component adheres to the sewer pipe. It is possible to suppress that the sewer pipe is corroded due to hardening or Cl.

、 At this time, the third load on the motor 30A of the dilution tank 30 is monitored by the control unit. Specifically, the magnitude of the third load detected at this time is the magnitude of the current consumption of the motor 30A of the dilution tank 30.

If the control unit determines that the magnitude of the third load of the motor 30A is not less than or equal to the predetermined value even after the predetermined time has elapsed (that is, the reaction between the polymer of the diluent T and the decomposer has not sufficiently proceeded), The decomposing agent input device 13 is controlled so that the decomposing agent is additionally input from the decomposing agent input device 13. At this time, the motor 30A of the dilution tank 30 is also continuously driven, and the reaction between the polymer of the diluent T and the decomposing agent can be further advanced in the dilution tank 30. Thus, in the dilution tank 30, the agitated material S and at least one of the second predetermined amount of water and hot water are agitated, and the agitated material S is diluted to the diluted material T in which the reaction between the polymer and the decomposing agent has progressed. Become. A configuration may be adopted in which a decomposing agent inlet is formed in the dilution tank 30 and a decomposing agent can be supplied from the decomposing agent input device 13 also to this decomposing agent inlet. Thus, when the additional decomposing agent is added, the decomposing agent can be directly injected into the dilution tank 30.

Next, the solid content is separated from the diluent T. First, when the control unit determines that the magnitude of the current consumption of the motor 30A (that is, the magnitude of the third load) is equal to or smaller than a predetermined value, the control unit causes the second on-off valve 16 in the closed state to be closed. It is left open. Then, the diluent T flows from the dilution tank 30 toward the separation unit 40.

(4) The input port of the waste disposal apparatus 1 is closed by the first lid 60. For this reason, by taking in air from the negative pressure eliminating portion 17A of the first ventilation path 17 into the first ventilation path 17, it is possible to prevent the inside of the dilution tank 30 from becoming a negative pressure. , And can be satisfactorily flowed toward the separation section 40. The drive of the motor 40C of the separation unit 40 is started by the control unit. At this time, the operation of the suction unit 19A is also started by the control unit.

The diluent T that has flowed into the drainage channel 15 flows into the separation unit 40, and the solid content of the diluent T is discharged from the solid discharge unit 40D by driving the motor 40C. The solids of the diluent T discharged from the solids discharge unit 40D are taken into the collection bag 40E attached to the tip of the solids discharge unit 40D. At this time, the odor generated in the solids discharge section 40D is guided to the input section 10 by the third ventilation path 19 and the suction section 19A. The water of the diluent T flows through the trap 15A to a drain (not shown).

The separating section 40 is in communication with the first ventilation path 17 via the second ventilation path 18. Thereby, the inside of the separation unit 40 is suppressed from being negative pressure, and the water of the diluent T can be satisfactorily flowed from the separation unit 40 toward the sewer pipe. The water of the diluent T remaining in the trap 15A is surely conveyed to the sewer pipe by vigorously supplying water to the trap 15A from a jet drain (not shown) connected to the trap 15A.

After the separation of the solid content from the diluent T is completed, by operating an operation unit (not shown), the

motors

motors

20G, 70A, 30A, and 40C is stopped, the control unit controls so that hot water is supplied from the second discharge unit 14B of the discharge unit 14. At this time, the

motors

20G, 70A, 30A, and 40C of the crushing unit 20, the mixer 70, the dilution tank 30, and the separation unit 40 are driven by the control unit, and the first on-off valve 12 and the second on-off valve 16 are opened.

Become. However, the negative pressure eliminating section 17A can prevent the dilution tank 30 and the separating section 40 from becoming negative pressure even when the charging section 10 is closed with the first lid 60.

The separation unit 40 of the first waste disposal apparatus 1 has a solids discharge unit 40D for discharging solids separated from the diluent T, one end of which is connected to the input unit 10 and the other end of which is a solids discharge unit 40D.

Therefore, the odor generated in the solids discharge section 40D can be guided to the input section 10 and the input section 10 can be deodorized by the deodorizing device 80.

The deodorizing device 80 of the first waste disposal apparatus 1 has an intake unit 80A that takes in air from the charging unit 10 and a blowing unit 80C that blows air to the charging unit 10.

The second on-off valve 16 is provided between the dilution tank 30 and the separation unit 40, and is provided between two downstream processing units (the dilution tank 30 and the separation unit 40) among all the processing units. Have been.

Next, the operation of the second waste disposal apparatus 4 will be described.

First, the operation in the processing mode in which the waste disposal apparatus 4 separates the waste D will be described. First, the first lid 60 is set in the upright state, the input port is opened, and the waste D is input into the input section 10. Based on the fact that the first lid 60 is in the upright state, the control unit starts the operation of the suction unit 80A and the blower unit 80C of the deodorization device 80. Next, the first lid 60 is placed in the lying state, the input port of the input section 10 is closed, and the operation section (not shown) is operated to operate the waste disposal apparatus 4.

The waste disposal device 4 first operates at least one of the first solenoid valve 14C and the second solenoid valve 14D by the control unit to remove at least one of the first predetermined amount of water and hot water from the discharge unit 14. It is supplied to the crushing unit 20. Thus, the filth D and at least one of water and hot water are put into the crushing unit 20. At this time, the first on-off valve 12 is in a closed state. The motor 20G of the crushing unit 20 is not driven when the control unit determines that the first lid 60 has at least one of the state in which the inlet is opened and the state in which the disintegrant is not charged. It is controlled by the control unit.

(4) When the control unit determines that the first lid 60 is in the state in which the inlet is closed and the state in which the decomposing agent is charged, the motor 20G of the crushing unit 20 is driven, and the waste D is crushed. At this time, the control unit estimates the amount of the input waste D based on the magnitude of the first load of the motor 20G. Specifically, the control unit detects the first load (that is, the power consumption of the motor 20G) related to the crushing unit 20 and crushes the waste D when the first load exceeds a predetermined value. Then, the amount of the waste D is estimated based on the time when the first load exceeds the predetermined value. The filth D is crushed in the crushing unit 20 to become the crushed material C. The control unit operates the decomposing agent introducing device 13 based on the signal corresponding to the magnitude of the first load, and injects a predetermined amount of the decomposing agent into the chute 21. The decomposing agent charged into the chute 21 flows into the mixer 70.

Next, in the mixer 70, the crushed material C, at least one of the first predetermined amount of water and hot water, and the decomposing agent are stirred, and the polymer that has absorbed and held the water and the decomposing agent are reacted, The water absorbed by the polymer is taken out. Thus, in the mixer 70, the crushed material C, at least one of water and hot water, and the decomposing agent are agitated into the agitated material S.

If the control unit determines that the magnitude of the second load of the motor 70A is not less than or equal to the predetermined value even after the predetermined time has elapsed (that is, the reaction between the polymer of the agitated product S and the decomposing agent has not sufficiently proceeded), the control unit decomposes. The disintegrating agent injecting device 13 is controlled so that an agent is additionally injected from the injecting agent injecting device 13. At this time, the motor 70A is continuously driven, and the mixer 70 can further promote the reaction between the polymer of the agitated substance S and the decomposing agent. Thus, in the mixer 70, the crushed material C, at least one of the first predetermined amount of water and hot water, and the decomposing agent are stirred, and the crushed material C is converted into the agitated material S, and the polymer of the agitated material S is decomposed. The reaction with the agent can proceed further.

At this time, the first electromagnetic valve 14C and the second electromagnetic valve 14D of the discharge unit 14 are operated by the control unit to supply at least one of the second predetermined amount of water and hot water from the discharge unit 14 to the crushing unit 20. At least one of the second predetermined amount of water and hot water is a predetermined amount with respect to the amount of the stirring object S. At this time, the motor 20G of the crushing unit 20 and the motor 70A of the mixer 70 are being driven. Thus, the inside of the crushing unit 20 and the inside of the mixer 70 can be washed while the stirred material S in the mixer 70 is surely conveyed into the dilution tank 30. The first ventilation path 17 suppresses the inside of the dilution tank 30 from becoming a positive pressure when at least one of the crushed material C and the second predetermined amount of water and hot water flows into the dilution tank 30. The second on-off valve 16 is in a closed state when at least one of the second predetermined amount of water and hot water and the agitated material S flow into the dilution tank 30.

(4) The input port of the waste disposal apparatus 4 is closed by the first lid 60. For this reason, by taking in air from the negative pressure eliminating portion 17A of the first ventilation path 17 into the first ventilation path 17, it is possible to prevent the inside of the dilution tank 30 from becoming a negative pressure. , And can be satisfactorily flowed toward the separation section 40. The drive of the motor 40C of the separation unit 40 is started by the control unit. At this time, the operation of the suction unit 19A is also started by the control unit.

The separating section 40 is in communication with the first ventilation path 17 via the second ventilation path 18. Thereby, the inside of the separation unit 40 is suppressed from being negative pressure, and the water of the diluent T can be satisfactorily flowed from the separation unit 40 toward the sewer pipe. The water of the diluent T remaining in the trap 15A is reliably transported to the sewer pipe by vigorously supplying water to the trap 15A from a jet drain (not shown) connected to the trap 15A.

motors

20G, 70A, 30A of the crushing unit 20, the mixer 70, the dilution tank 30, and the separation unit 40 are operated. , 40C are stopped. Thus, the processing mode ends.

Next, the operation in the cleaning mode in which the waste disposal apparatus 4 cleans the input unit 10 and all the processing units will be described. When a predetermined time elapses after the driving of each of the

motors

20G, 70A, 30A, and 40C is stopped, the control unit controls so that hot water is supplied from the second discharge unit 14B of the discharge unit 14. The discharge unit 14 discharges hot water to the charging unit 10 in the cleaning mode. At this time, the control unit drives the

motors

20G, 70A, 30A, and 40C to open the first on-off valve 12 and close the second on-off valve 16 of the waste disposal apparatus 4. That is, in the cleaning mode, the waste disposal device 4 discharges hot water from the discharge unit 14 while driving all the processing units. Accordingly, the waste disposal apparatus 4 closes the second on-off valve 16 in the cleaning mode and supplies hot water to the crushing unit 20, the mixer 70, and the dilution tank 30 (hereinafter, also referred to as a processing unit excluding the separation unit 40). To store.

At this time, the control unit drives the

motors

20G, 70A, 30A alternately in the forward and reverse directions. As a result, the stored hot water flows so as to be stirred in the processing unit excluding the separation unit 40, so that the crushed material C, the agitated material S, and The hot melt and the adhesive tape contained in the diluent T are softened and the adhesive strength is reduced, and the hot melt and the adhesive tape are easily peeled off from the inner surface of the processing section excluding the separation section 40.

The waste disposal apparatus 4 operates the heaters H1, H2, H3 provided in each of the processing units except for the separation unit 40 to heat the hot water stored in the processing units except for the separation unit 40. Thereby, the hot melt or the adhesive tape adhered to the inner surface of the processing unit excluding the separation unit 40 is further softened to reduce the adhesive force, and the hot melt or the adhesive tape is further removed from the inner surface of the processing unit excluding the separation unit 40. Can be peeled off satisfactorily.

In the cleaning mode, the waste treatment apparatus 4 is configured such that hot water at 62 ° C. to 65 ° C. is supplied for 30 minutes or more, and hot water at 72 ° C. to 87 ° C. is used for 15 seconds or more in the processing unit excluding the separation unit 40. By storing in the processing section, sterilization in the processing section excluding the separation section 40 can be performed.

Next, the waste disposal apparatus 4 opens the second on-off valve 16 in the closed state, and operates the heater H4. Then, together with the hot water stored in the processing unit excluding the separation unit 40, the crushed material C including the hot melt and the adhesive tape adhered to the inner surface of the processing unit excluding the separation unit 40, the agitated material S, and the diluent T flows into the separation unit 40.

The separation unit 40 includes solids of the crushed material C, the agitated material S, and the diluent T containing the hot melt and the adhesive tape adhered to the inner surface of the processing unit excluding the separation unit 40 (the processing excluding the separation unit 40). (Including hot melt and adhesive tape attached to the inner surface of the solid portion), and the separated solid is discharged from the solid discharge portion 40D.

At this time, the hot melt or the adhesive tape contained in the diluent T adhered to the inner surface of the separation unit 40 is softened by the hot water stored in the processing unit excluding the separation unit 40 and the adhesive strength is reduced. Becomes smaller. As a result, the solid content of the diluent T including the hot melt and the adhesive tape adhered to the inner surface of the separation unit 40 (including the hot melt and the adhesive tape adhered to the inner surface of the separation unit 40) is also reduced. And is discharged from the solids discharge section 40D. At this time, the hot water at 62 ° C. to 65 ° C. is continuously fed into the separation unit 40 for at least 30 minutes and the hot water at 72 ° C. to 87 ° C. for 15 seconds or more. By setting the state close to the state where hot water is stored in the section 40, sterilization in the separation section 40 can also be performed.

As described above, the second filth disposal apparatus 4 discharges hot water from the discharge unit 14 to the charging unit 10 in the cleaning mode, so that the crushed material C, the stirred material S, and the dilution remaining in all the processing units are discharged. The object T can be washed out and all the processing units can be put in a good state.

Therefore, the second waste disposal apparatus 4 can operate well.

湯 The temperature of the hot water in the second waste disposal apparatus 4 is 40 ° C to 90 ° C. Therefore, the hot melt or the adhesive tape contained in the waste D is softened to reduce the adhesive strength, the hot melt or the adhesive tape is easily peeled from the inner surface of all the processing units, and the sterilization in all the processing units is performed. Can be.

The second waste disposal apparatus 4 includes a second on-off valve 16 between two downstream processing units of all the processing units, and closes the second on-off valve 16 in the cleaning mode to disconnect the separation unit 40.

The total processing time in the first group G1 (the charging unit 10, the crushing unit 20, the chute 21, and the mixer 70) is 5 seconds (the charging unit 10) +20 seconds (the crushing unit 20) +5 seconds (the chute 21) +60 seconds ( Mixer 70) = 90 seconds. The total processing time in the second group G2 (dilution tank 30) is 85 seconds (dilution tank 30) = 85 seconds. In the third group G3, the total processing time in the (separator 40 and the trap 15A) is 75 seconds (separator 40) +5 seconds (trap 15A) = 80 seconds.

That is, the processing time of the group on the downstream side is shorter than that of the group on the upstream side.

１Each of the first group G1, the second group G2, and the third group G3 is configured to be removable from the waste disposal apparatus 5. Specifically, when removing the first group G1 from the waste disposal apparatus 5, the motor 20G and the motor 70A are left inside the waste disposal apparatus 5. When removing the second group G2 from the waste disposal apparatus 5, the motor 30A is left inside the waste disposal apparatus 5. When removing the third group G3 from the waste disposal apparatus 5, the motor 40C is left inside the waste disposal apparatus 5. The first ventilation path 17, the second ventilation path 18, and the third ventilation path 19 are left in the waste disposal apparatus 5 when any of the groups is removed.

Next, the operation of the third waste disposal apparatus 5 will be described. First, the first lid 60 is placed in an upright state, the inlet is opened, and a predetermined amount of waste D is injected into the inlet 10. Based on the fact that the first lid 60 is in the upright state, the control unit starts the operation of the suction unit 80A and the blower unit 80C of the deodorization device 80. Next, the first lid 60 is placed in the lying state, the slot of the slot 10 is closed, and the operation unit (not shown) is operated to operate the waste disposal apparatus 5.

The waste treatment device 5 first operates at least one of the first solenoid valve 14C and the second solenoid valve 14D by the control unit to remove at least one of the first predetermined amount of water and hot water from the discharge unit 14. It is supplied to the crushing unit 20. In this way, a predetermined amount of filth D and at least one of water and hot water are introduced into the crushing unit 20. At this time, the first manual on-off valve 12A is open and the first on-off valve 12 is closed. The motor 20G of the crushing unit 20 has a state in which the first lid 60 has opened the charging port, a state in which the dissolving agent has not been charged, a state in which the inspection port 30B is not closed by the lid 30C, and a state in which the inspection port 40A is closed by the lid 40B. When the control unit determines that the state is not closed, the control unit controls so as not to drive.

Control is performed when the first lid 60 is closed, the dissolving agent is charged, the inspection port 30B is closed by the lid 30C, and the inspection port 40A is closed by the lid 40B. When the unit is determined, the motor 20G of the crushing unit 20 is driven, and a predetermined amount of the waste D is crushed.

At this time, the control unit estimates the amount of the predetermined amount of filth D input based on the magnitude of the first load of the motor 20G. Specifically, the control unit detects the first load (that is, the power consumption of the motor 20G) related to the crushing unit 20 and crushes the waste D when the first load exceeds a predetermined value. Then, the amount of the waste D is estimated based on the time when the first load exceeds the predetermined value. A predetermined amount of filth D is crushed in the crushing unit 20 to become crushed material C. The control unit operates the decomposing agent introducing device 13 based on the signal corresponding to the magnitude of the first load, and injects a predetermined amount of the decomposing agent into the chute 21. A predetermined amount of the decomposing agent supplied to the chute 21 flows into the mixer 70.

Next, in the mixer 70, the crushed material C, at least one of the first predetermined amount of water and hot water, and the predetermined amount of the decomposer are stirred, and the polymer having absorbed and retained the water is reacted with the decomposer. To take out the water absorbed and retained by the polymer. In this way, in the mixer 70, the crushed material C, at least one of water and hot water, and a predetermined amount of the decomposing agent are stirred to form the stirred material S.

If the control unit determines that the magnitude of the second load of the motor 70A is not less than or equal to the predetermined value even after the predetermined time has elapsed (that is, the reaction between the polymer of the agitated product S and the decomposing agent has not sufficiently proceeded), the control unit decomposes. The disintegrating agent injecting device 13 is controlled so that an agent is additionally injected from the injecting agent injecting device 13. At this time, the motor 70A is continuously driven, and the mixer 70 can further promote the reaction between the polymer of the agitated substance S and the decomposing agent. Thus, in the mixer 70, the crushed material C, at least one of the first predetermined amount of water and hot water, and the decomposing agent are agitated, and the crushed material C is converted into the agitated material S. The reaction with can be further advanced.

Next, the magnitude of the current consumption of the motor 70A (that is, the magnitude of the second load) is equal to or less than a predetermined value, the first group G1 is not empty, only the agitated material S exists, and the second group G2 When the control unit determines that the inside is empty, the first open / close valve 12 in the closed state is opened by the control unit. Then, the agitated material S flows into the dilution tank 30 via the discharge path 11.

At this time, the first electromagnetic valve 14C and the second electromagnetic valve 14D of the discharge unit 14 are operated by the control unit to supply at least one of the second predetermined amount of water and hot water from the discharge unit 14 to the crushing unit 20. At least one of the second predetermined amount of water and hot water is a predetermined amount with respect to the amount of the stirring object S. At this time, the motor 20G of the crushing unit 20 and the motor 70A of the mixer 70 are being driven. Thus, the inside of the crushing unit 20 and the inside of the mixer 70 can be washed while the stirred material S in the mixer 70 is surely conveyed into the dilution tank 30. The first ventilation path 17 suppresses the inside of the dilution tank 30 from becoming a positive pressure when at least one of the crushed material C and the second predetermined amount of water and hot water flows into the dilution tank 30. The second on-off valve 16 is in a closed state when at least one of the second predetermined amount of water and hot water and the agitated material S flow into the dilution tank 30, and the second manual on-off valve 16A is in an open state. It is.

では In the first group G1, a predetermined amount of the filth D is made into the stirrer S in about 90 seconds, and the stirrer S and at least one of the second predetermined amount of water and hot water flow into the second group G2. When the control unit detects that the inside of the first group G1 has changed from a non-empty state to an empty state, the control unit sets the open first on-off valve 12 to a closed state. Thus, the first group G1 is again in a state in which a predetermined amount of the waste D can be made into the agitated material S. That is, the waste disposal apparatus 5 can perform the separation processing of the waste such as the waste D and the stirrer S in parallel in the first group G1 and the second group G2. Thereby, the waste disposal apparatus 5 can increase the throughput of the waste D as a whole.

Next, at least one of the second predetermined amount of water and hot water and the stirred material S are diluted in the dilution tank 30 to make the stirred material S a diluted material T. At this time, the second manual on-off valve 16A is open and the second on-off valve 16 is closed. First, the drive of the motor 30A of the dilution tank 30 is started by the control unit. As a result, the propeller (not shown) of the dilution tank 30 rotates, and the second predetermined amount of at least one of water and hot water and the agitated material S are agitated. Become. Accordingly, the concentration of Ca (calcium) or Cl (chlorine) of the decomposing agent contained in the agitated material S in the agitated material S can be reduced by using the diluent T, and the Ca component adheres to the sewer pipe. It is possible to suppress that the sewer pipe is corroded due to hardening or Cl.

Next, the solid content is separated from the diluent T. First, the control unit determines that the magnitude of the current consumption of the motor 30A (that is, the magnitude of the third load) is equal to or smaller than a predetermined value, and that the second group G2 is not empty and the third group G3 is empty. When the control unit determines that the second open / close valve 16 is in the closed state, the second open / close valve 16 in the closed state is opened by the control unit. Then, the diluent T flows from the dilution tank 30 toward the separation unit 40.

{Circle around (2)} In the second group G2, the mixture S is turned into the diluent T in about 85 seconds, and the diluent T flows into the third group G3. Upon detecting that the inside of the second group G2 has changed from a non-empty state to an empty state, the control unit closes the open second on-off valve 16. In this way, the second group G2 is in a state where the stirred substance S can be turned into the diluted substance T again. In other words, the waste disposal apparatus 5 can perform the separation processing of the waste such as the waste D, the agitated material S, and the diluent T in parallel in the first group G1, the second group G2, and the third group G3. Thereby, the waste disposal apparatus 5 can increase the throughput of the waste D as a whole.

投入 The input port of the waste disposal apparatus 5 is closed by the first lid 60. For this reason, by taking in air from the negative pressure eliminating portion 17A of the first ventilation path 17 into the first ventilation path 17, it is possible to prevent the inside of the dilution tank 30 from becoming a negative pressure. , And can be satisfactorily flowed toward the separation section 40. The drive of the motor 40C of the separation unit 40 is started by the control unit. At this time, the operation of the suction unit 19A is also started by the control unit.

The separating section 40 is in communication with the first ventilation path 17 via the second ventilation path 18. Thereby, the inside of the separation unit 40 is suppressed from being negative pressure, and the water of the diluent T can be satisfactorily flowed from the separation unit 40 toward the sewer pipe. The water of the diluent T remaining in the trap 15A is surely conveyed to the sewer pipe by vigorously supplying water to the trap 15A from a jet drain (not shown) connected to the trap 15A. In the third group G3, the solids can be separated from the diluent T in about 80 seconds, and the water of the diluent T can be flown to the sewer. When the inside of the third group G3 changes from a state that is not empty to an empty state, the third group G3 is in a state where the solids can be separated from the diluent T again.

処理 The processing time of the third group G3 is shorter than the processing time of the first group G1 and the second group G2, and the processing time of the second group G2 is shorter than the processing time of the first group G1. For this reason, when the wastes such as the wastes D, the agitated materials S, and the diluents T are separated in parallel in each group, the processing in the downstream group ends earlier than the processing in the upstream group. Immediately after the processing is completed in the group, the stirred substance S and the diluted substance T can flow into the downstream group.

motors

20G, 70A, 30A, and 40C of the crushing unit 20, the mixer 70, the dilution tank 30, and the separation unit 40 are driven by the control unit, and the first on-off valve 12 and the second on-off valve 16 are opened. State. Thereby, the waste disposal apparatus 5 is cleaned so that the waste D, the crushed substance C, the agitated substance S, the diluent T, and the like do not remain in the waste disposal apparatus 5, and the Ca component is contained in the waste disposal apparatus 5. It is possible to suppress adhesion and solidification, and corrosion of the inside of the waste disposal apparatus 5 by Cl.

Next, a case where one of the groups (the first group G1, the second group G2, and the third group G3) is exchanged will be described. When removing the first group G1, first, the first manual on-off valve 12A and the first on-off valve 12 are closed. Then, the discharge path 11 is separated into the first manual opening / closing valve 12A side and the first opening / closing valve 12 side at the first connection portion 11A. Next, one end of the first ventilation path 17 and one end of the third ventilation path 19 are removed from the charging section 10. The crushing unit 20 is removed with the motor 20G left in the waste disposal apparatus 5. The mixer 70 is removed with the motor 70A left in the waste disposal apparatus 5.

When removing the second group G2, first, the first manual on-off valve 12A, the first on-off valve 12, the second manual on-off valve 16A, and the second on-off valve 16 are closed. Next, at the first connection portion 11A, the discharge passage 11 is separated into the first manual opening / closing valve 12A side and the first opening / closing valve 12 side.

<Embodiment 6>
The waste disposal apparatus 6 of Embodiment 6 of the fourth waste disposal apparatus and the fifth waste disposal apparatus is an apparatus for processing a used paper diaper Dd as an object to be treated. The disposable diaper is made of pulp, plastic, superabsorbent polymer (SAP, superabsorbent polymer, hereinafter simply referred to as polymer), or the like. Used disposable diapers are converted into pulp or polymer, and the moisture of dirt such as urine is absorbed. The water-absorbing performance of the polymer that has absorbed water is suppressed by performing the treatment using the treating agent. Specifically, the treating agent is a chemical containing divalent metal ions such as calcium chloride (CaCl ₂ ) and calcium acetate (Ca (CH ₃ COO) ₂ ), and by reacting these with a polymer. Water is separated from the polymer that has absorbed the water, and the polymer from which the water has been separated is again brought into an irreversible state in which the water cannot be absorbed. Even in the case where the used disposable diaper Dd contains a polymer that does not absorb moisture, the treatment with the treatment agent renders it impossible to absorb moisture.

The fourth and fifth filth disposal apparatuses 6 include an input unit 10, a processing unit 90, and a control unit 50, as shown in FIG. The dispensing section 10 is charged with a disposable diaper Dd as a processing object having a water-absorbing polymer.

The status of the unit 40) is determined. For example, the determination unit 51 determines each motor 20G as a measurement result measured by the first measurement unit 20H, the second measurement unit 70B, the third measurement unit 30D, and the fourth measurement unit 40F as information on the operation state of the processing unit 90. , 70A, 30A, and 40C, the status of each unit (the crushing unit 20, the mixer 70, the dilution tank 30, and the separation unit 40) of the processing unit 90 can be determined. In this case, the first measurement unit 20H, the second measurement unit 70B, the third measurement unit 30D, and the fourth measurement unit 40F function as an information acquisition unit that acquires a power consumption value as information regarding the operation state of the processing unit 90. .

The notification unit 53 according to the present embodiment is a display that displays information about the operation status of the waste disposal apparatus 6 in characters or graphics. The notification unit 53 is arranged, for example, outside the input port of the input unit 10, as shown in FIG. Examples of the information on the operating status notified by the notifying unit 53 include the state of the disposable diaper Dd as an object to be processed and information related thereto (for example, the number of disposable diapers Dd measured by the measuring unit 52, the weight of the disposable diaper Dd), The operating state of each part (the crushing unit 20, the mixer 70, the dilution tank 30, and the separation unit 40) of the processing unit 90 and information related thereto (for example, the first measurement unit 20H, the second measurement unit 70B, the third measurement unit 30D, And the state of each unit (the crushing unit 20, the mixer 70, the dilution tank 30, and the separation unit 40) of the processing unit 90 (for example, the current processing step, the processing of the disposable diaper Dd). The time from the start to the present, the expected time from the present to the end of the process, the expected time from the present to the next disposable diaper Dd, etc.) And that the remaining amount of the treatment agent, the presence or absence of abnormality occurrence, contents, etc., of the abnormality that has occurred, and the like.

(4) The storage unit 54 according to the present embodiment stores data of information listed as information on the operation status notified by the notification unit 53 and the like. The storage unit 54 is a storage medium capable of storing such information data and a control program for the apparatus. The storage unit 54 measures the measurement result of the measurement unit 52, the amount of the treatment agent supplied from the treatment agent introduction unit 23, and the first measurement unit 20H, the second measurement unit 70B, the third measurement unit 30D, and the fourth measurement unit 40F. Various information acquired during the operation of the waste disposal apparatus 6 such as a measured value to be performed, a load reduction time acquired by the control unit 50 based on the measured values, and a determination result of the determination unit 51 are related to the operation status of the waste disposal apparatus 6. Store as information.

送信 The transmitting unit 55 according to the present embodiment transmits data of information listed as information on the operating status notified by the notifying unit 53 and the like. The transmission unit 55 includes, for example, a known communication device or the like. The information transmitted from the transmitting unit 55 can be received by an external receiving unit such as a management device of a management center or a portable terminal.

Next, the operation of the fourth and fifth waste disposal apparatuses 6 will be described.
First, the first lid 60 of the input unit 10 is opened, and the used paper diaper Dd is input into the input unit 10 (input step). When the disposable diaper Dd is inserted from the input unit 10, the control unit 50 starts the operation of the crushing unit 20 and the mixer 70 and executes control to close the first on-off valve 12 of the discharge path 11. Thus, the processing of the disposable diaper Dd is started. When the disposable diapers Dd are inserted from the input unit 10, the measuring unit 52 counts the number of the disposable diapers Dd. Furthermore, in the case of the present embodiment, the measuring unit 52, which is a photoelectric sensor, measures the detection time for each paper diaper Dd. Based on this, the control unit 50 estimates the size of the paper diaper Dd. Specifically, the control unit 50 estimates whether the diaper is a stool diaper or a urine diaper in accordance with the length of the detection time of the diaper Dd measured by the measurement unit 52. When one disposable diaper is used, weighting is performed according to the type of disposable diaper, for example, by using 0.5 urinal disposable diapers. The control unit 50 determines the state of the disposable diapers Dd based on the number of disposable diapers Dd, which is the measurement result measured by the measuring unit 52, and determines the amount of the treatment agent to be introduced. The control unit 50 causes the processing agent input unit 23 to input the determined input amount of the processing agent (processing agent input step). In the case of the present embodiment, in the processing agent charging step in the normal operation, the processing agent including calcium acetate and the processing agent including calcium chloride are supplied from each of the first processing agent input section 23A and the second processing agent input section 23B. . The control unit 50 executes opening / closing control of the electromagnetic valve 14E, and supplies water according to the amount of the disposable diaper Dd measured by the measuring unit 52 from the discharge unit 14.

In the processing agent supply step, when the control unit 50 detects that the amount of the processing agent that can be supplied from the processing agent supply unit 23 is insufficient with respect to the determined supply amount, the control unit 50 executes control to stop the operation of the processing unit 90. . In the case of the present embodiment, when the control unit 50 detects the shortage of the remaining amount with respect to the amount of the processing agent according to the number of the disposable diapers Dd, the control unit 50 stops each unit of the processing unit 90 and stops the processing. I do. The control unit 50 causes the notification unit 53 to notify the shortage of the remaining amount of the processing agent. At this time, for example, when the control unit 50 confirms replenishment of the processing agent into the processing agent input unit 23, or when it is confirmed that the processing agent is manually input from the input port of the input unit 10, the control unit 50 performs processing. If it can be confirmed that the state has become normally executable, the control of automatically restarting the operation of the processing unit 90 may be executed.

(4) The disposable diaper Dd supplied from the input unit 10 falls into the crushing unit 20 and is crushed (crushing step). The crushing unit 20 crushes the paper diaper Dd together with the water supplied from the discharge unit 14. At this time, the control unit 50 measures the magnitude of the current consumption of the motor 20G as information on the operation state of the processing unit by the first measurement unit 20H. The measured current consumption value is stored in the storage unit 54. The control unit 50 continues to rotate the rotary blade by controlling the drive of the motor 20G until the amount of current consumption becomes equal to or less than a predetermined value. In the crushing step, the disposable diaper Dd is finely crushed to be crushed material C and gradually falls to the lower chute 21, so that as the crushing proceeds, the load on the motor 20G gradually decreases. The control unit 50 monitors the change of the value measured by the first measurement unit 20H, and determines the state of the crushing unit 20 by the determination unit 51.

(4) When the magnitude of the current consumption of the motor 20G measured by the first measuring unit 20H is equal to or smaller than a predetermined value, the determining unit 51 determines that the state of the crushing unit 20 is “no load (idle operation)”. When the magnitude of the current consumption of the motor 20G measured by the first measuring unit 20H is not smaller than or equal to the predetermined value, the determining unit 51 determines that the state of the crushing unit 20 is “crushing”. When the state of the crushing unit 20 becomes “no load” within a predetermined time from “under crushing”, the determination unit 51 determines that the state is “crushed”. In this case, the control unit 50 stops the operation of the crushing unit 20 and starts the operation of the mixer 70. At this time, the control unit 50 measures the processing time in the crushing unit 20, and determines an additional amount of the processing agent to be added according to the measurement result. Specifically, the control unit 50 estimates the number of the disposable diapers Dd based on the time when the state of the crushing unit 20 is “under crushing”, and compares the estimated number with the number of the disposable diapers Dd measured by the measuring unit 52. I do. When the estimated number of disposable diapers Dd is larger than the measurement result of the measuring unit 52, the control unit 50 determines an additional amount of the processing agent according to the difference, and causes the processing agent input unit 23 to additionally input the amount. On the other hand, when the estimated number of the disposable diapers Dd is smaller than the measurement result of the measurement unit 52, the control unit 50 determines the additional amount to be 0. That is, in this case, the control unit 50 does not add the processing agent.

(4) The crushed material C dropped from the crushing unit 20 via the chute 21 is mixed by the mixer 70 (mixing step). In the mixing process, the crushed material C, the water supplied from the discharge unit 14, and the processing agent input from the processing agent input unit 23 are mixed in the mixer 70. As a result, the polymer that has absorbed the water and the treating agent react with each other to generate a mixture M in which the solid component of the disposable diaper Dd containing the polymer and the water irreversibly separated from the polymer are mixed. At this time, the control unit 50 measures the magnitude of the current consumption of the motor 70A by the second measuring unit 70B as information on the operation state of the processing unit. The measured current consumption value is stored in the storage unit 54. The control unit 50 controls the drive of the motor 70A and keeps rotating the rotary blade (not shown) until the magnitude of the current consumption becomes equal to or smaller than the predetermined magnitude. In the mixing step, as the reaction between the polymer and the treatment agent progresses, the water is separated and the viscosity of the mixture M decreases, so that the load on the motor 70A gradually decreases. The control unit 50 monitors the change of the value measured by the second measurement unit 70B, and determines the state of the mixer 70 by the determination unit 51.

As shown in FIG. 8, the current consumption of the motor 70A of the mixer 70 is maintained at the value A for a while after executing the mixing process, and thereafter gradually decreases from the value A to reach the value B. Is maintained. Immediately after the start of mixing the crushed material C and the treatment agent in the mixer 70, the current consumption of the motor 70A of the mixer 70 indicates the value A. The current consumption of the motor 70A gradually decreases from the value A as the reaction between the polymer and the treatment agent progresses. When the reaction between the polymer and the treating agent is almost completed, the current consumption of the motor 70A of the mixer 70 shows a value B smaller than the value A.

If the magnitude of the current consumption of the motor 70A measured by the second measuring unit 70B is equal to or smaller than the first predetermined value, the determining unit 51 determines that the state of the mixer 70 is “no load (idle operation)”. I do. This first predetermined value is set as a value smaller than the value B in FIG. When the magnitude of the current consumption of the motor 70A measured by the second measuring unit 70B is equal to or larger than the second predetermined value, the determining unit 51 determines that the state of the mixer 70 is in the process of causing the polymer to react with the treating agent. It is determined that "polymer processing is in progress". This second predetermined value is set as a value smaller than the value A and larger than the value B in FIG. When the current consumption of the motor 70A measured by the second measuring unit 70B is not greater than or equal to the second predetermined value within a predetermined time from the state where the mixer 70 is in the “polymer processing” state, The determination unit 51 determines that the state of the mixer 70 is “polymer processed”. In this case, the control unit 50 closes the second on-off valve 16 of the drain passage 15 and opens the first on-off valve 12 of the discharge passage 11 to introduce the mixture M into the dilution tank 30. At this time, the control unit 50 also starts the operation of the dilution tank 30.

The mixture M discharged from the mixer 70 is introduced into the dilution tank 30 via the discharge path 11 and is diluted (dilution process). In the dilution process, the mixture M is diluted by stirring the mixture M and water in the dilution tank 30. In the dilution step, the mixture M is diluted such that the concentration of the treating agent component contained in the mixture M becomes a predetermined value or less (for example, the chlorine concentration is 300 ppm or less). As a result, a dilution T in which the mixture M is diluted to a concentration that can be discharged to the sewage is generated. At this time, the determination unit 51 determines the number of the paper diapers Dd measured by the measurement unit 52 and the number of the paper diapers Dd estimated by the control unit 50 based on at least one of the measurement results of the first measurement unit 20H. The state of the paper diaper Dd as a processing object is determined, and the control unit 50 supplies a predetermined amount of water from the discharge unit 14 according to the determination result of the determination unit 51. Thereby, water is supplied to the dilution tank 30 while washing the crushing unit 20, the chute 21, the mixer 70, and the discharge path 11. Since calcium acetate as a treating agent does not contain Cl (chlorine), the amount of water to be diluted can be reduced as compared with the case where only calcium chloride is used as a treating agent as in the related art.

In the dilution step, the control unit 50 measures the magnitude of the current consumption of the motor 30A by the third measurement unit 30D as information on the operation state of the processing unit. The measured current consumption value is stored in the storage unit 54. The control unit 50 controls the driving of the motor 30A and keeps rotating the propeller (not shown) until the amount of current consumption becomes equal to or smaller than a predetermined value. In the dilution step, the viscosity decreases as the water content of the mixture M increases, so that the load on the motor 30A gradually decreases. The control unit 50 monitors the fluctuation of the value measured by the third measurement unit 30D, and determines the state of the dilution tank 30 by the determination unit 51.

When the magnitude of the current consumption of the motor 30A measured by the third measuring unit 30D is equal to or smaller than the first predetermined value, the determining unit 51 determines that the state of the dilution tank 30 is “no load (idle operation)”. judge. When the magnitude of the current consumption of the motor 30A measured by the third measurement unit 30D is equal to or larger than the second predetermined value, the determination unit 51 determines that the state of the dilution tank 30 is “dilution process”. This second predetermined value is set as a value larger than the first predetermined value. When the magnitude of the current consumption of the motor 30A measured by the third measuring unit 30D does not exceed the second predetermined value within a predetermined time from the state of the dilution tank 30 being “dilution processing” The determination unit 51 determines that the state of the dilution tank 30 is “diluted”. In this case, the control unit 50 opens the second on-off valve 16 of the drainage channel 15 to discharge the diluent T from the dilution tank 30 and starts the operation of the separation unit 40.

(4) The diluent T discharged from the dilution tank 30 is introduced into the separation unit 40 via the drainage channel 15 and is separated (separation step). In the separation process, the diluent T is separated into the solid content Sc and the water L in the separation unit 40. The solid content Sc separated in the separation unit 40 is stored in the collection bag 40E via the solid content discharge unit 40D. The water L separated in the separation section 40 is discharged from the downstream drainage channel 15C, and discharged to the external sewer through the trap 15A. In the trap 15A, there is a possibility that the solid content Sc discharged to the downstream drainage channel 15C without being separated in the separation unit 40 may stay. Eject periodically to force discharge.

In the separation step, the control unit 50 measures the magnitude of the current consumption of the motor 40C by the fourth measurement unit 40F as information on the operation state of the processing unit. The measured current consumption value is stored in the storage unit 54. The control unit 50 continues to rotate the screw by controlling the drive of the motor 40C until the amount of current consumption becomes equal to or less than a predetermined amount. In the separation step, the load on the motor 40C gradually decreases as the separation of the solid content Sc and the water L from the diluent T progresses. The control unit 50 monitors the change of the value measured by the fourth measurement unit 40F, and determines the state of the separation unit 40 by the determination unit 51.

(4) If the magnitude of the current consumption of the motor 40C measured by the fourth measuring unit 40F is equal to or smaller than a predetermined value, the determining unit 51 determines that the state of the separating unit 40 is “no load (idle operation)”. When the magnitude of the current consumption of the motor 40C measured by the fourth measuring unit 40F is equal to or larger than a predetermined value, the determining unit 51 determines that the state of the separating unit 40 is “separating”. When the status of the separation unit 40 changes from “state of separation processing” to “no load” within a predetermined time, the determination unit 51 determines that the state of the separation unit 40 is “separation processing completed”. Is determined. In this case, the control unit 50 stops the operation of the separation unit 40. Thus, the processing of the disposable diaper Dd is completed.

Next, a method for correcting an abnormality in the waste disposal apparatus 6 will be described. When an abnormality occurs in the crushing step, for example, in the crushing step, in spite of the disposable diaper Dd being input, if there is no change in the crushing unit 20 from the “no load” state for a predetermined time, The determination unit 51 determines that an abnormality has occurred. Specifically, it is conceivable that the paper diaper Dd may be jammed in the charging section 10 on the upstream side of the crushing section 20. In this case, the determination unit 51 determines that an abnormality of “clogging” has occurred in the crushing process. In this case, the control unit 50 stops the operation of the crushing unit 20 and causes the notification unit 53 to notify that an abnormality has occurred in the crushing process. In this case, the operator opens the first lid 60 and checks the inside of the input unit 10 to eliminate the jam of the paper diaper Dd. Thereafter, the operation of the crushing unit 20 is restarted.

In the crushing process, if the state of “under crushing” does not change even after a predetermined time has passed after the disposable diaper Dd is input, the determination unit 51 determines that excessive input of the disposable diaper Dd or accumulation of dirt has occurred (“overload”). Is determined). In this case, the control unit 50 stops the operation of the crushing unit 20 and causes the notifying unit 53 to notify. In this case, the operator opens the first lid 60 and checks the amount of the disposable diaper Dd in the dispensing section 10. When it is confirmed that the disposable diapers Dd are excessively loaded, some disposable diapers Dd are taken out. On the other hand, when it is confirmed that the number of the disposable diapers Dd in the input unit 10 is equal to or less than the normal number, accumulation of dirt is assumed. In this case, the washing mode of the crushing unit 20 is executed. That is, the washing mode of the crushing unit 20 is started by an operator operating an operation button after an abnormal state is confirmed by the operator.

When the washing mode of the crushing unit 20 is started by the operation of the operation button by the operator, the control unit 50 first stops the operation of the crushing unit 20 and performs the mixing process which is the next process of the crushing process. Upon completion, the mixer 70 is emptied. Next, the control unit 50 executes a control of repeating the forward rotation and the reverse rotation drive of the motor 20G while supplying water from the discharge unit 14. Thereafter, the control unit 50 controls the motor 20G until the crushing unit 20 enters the “no load” state, that is, until the current consumption of the motor 20G measured by the first measuring unit 20H becomes smaller than a predetermined value. Drive forward. While the crushing unit 20 is executing the cleaning mode, the control unit 50 notifies the notification unit 53 that the crushing unit 20 is executing the cleaning mode. It is preferable that the washing mode of not only the crushing unit 20 but also each unit of the processing unit 90 described below is performed using hot water. This is because accumulated dirt is easier to remove than washing using only water. In the cleaning mode of the crushing unit 20, for example, calcium acetate as a treatment agent may be manually input from the input unit 10. In this case, the calcium acetate may be a solid or an aqueous solution. When the component of the pressure-sensitive adhesive contained in the disposable diaper Dd is attached, it is preferable because it is easily peeled off by the action of calcium acetate added additionally.

If an abnormality occurs in the mixing process, for example, if the state of “no load” does not change even after a predetermined time has elapsed even though the operation of the mixer 70 has been started, the determination unit 51 generates an abnormality. It is determined that it has been performed. Specifically, it is conceivable that clogging of the crushed material C has occurred in the chute 21 on the upstream side of the mixer 70. In this case, the determination unit 51 determines that an abnormality of “clogging” has occurred in the mixing process. In this case, the control unit 50 operates the crushing unit 20 while supplying water from the discharge unit 14, and causes the crushed material C stuck in the chute 21 to drop into the mixer 70. Thereafter, when the control unit 50 confirms that the abnormal state of the mixer 70 has been resolved, the normal operation of the mixer 70 is restarted. On the other hand, if the abnormal state of the mixer 70 has not been eliminated, the control unit 50 causes the notification unit 53 to notify that an abnormality has occurred in the mixing process, and stops the entire waste disposal apparatus 6.

In the mixing step, if the state of “polymer processing” does not change even after the lapse of a predetermined time, the determination unit 51 determines that the reaction between the polymer and the processing agent is not sufficient. In this case, the control unit 50 executes control to cause the processing agent input unit 23 to input an additional processing agent. The input amount of the treatment agent is determined based on the measurement value of the second measurement unit 70B at the time when the reaction is determined to be insufficient. That is, the determination unit 51 determines the degree of progress of the process of causing the polymer in the state of the paper diaper Dd to react with the processing agent based on the value of the current consumption of the motor 70A measured by the second measurement unit 70B. The control unit 50 determines the amount of the processing agent to be re-input from the processing agent input unit 23 based on this.

In the mixing step, when the state of “polymer processing” does not change even after the predetermined time has passed even though the processing agent is re-input, the determination unit 51 determines that accumulation of dirt has occurred (“cleaning required”). Is determined). In this case, the control unit 50 stops the operation of the mixer 70 and executes the cleaning mode of the mixer 70. In the cleaning mode of the mixer 70, the control unit 50 controls the motor 70A while supplying water from the discharge unit 14 and supplying the processing agent from the processing agent input unit 23 with the first on-off valve 12 of the discharge path 11 closed. The control for repeating the forward rotation and the reverse rotation drive is executed. The processing agent supplied in the cleaning mode is only the processing agent containing calcium acetate supplied from the first processing agent supply section 23A. Thereafter, the control unit 50 controls the motor 70A until the mixer 70 enters the “polymer-processed” state, that is, until the magnitude of the current consumption of the motor 70A measured by the second measurement unit 70B becomes smaller than a predetermined value. Drive forward. While the cleaning mode of the mixer 70 is being executed, the control unit 50 notifies the notification unit 53 that the cleaning mode of the mixer 70 is being executed. When the control unit 50 confirms that the state of the mixer 70 has changed from the “polymer processing” state to the “polymer processed” state, the control unit 50 stops the notification by the notification unit 53. On the other hand, if the abnormal state of the mixer 70 is not resolved, the control unit 50 notifies the notification unit 53 of the fact and stops the entire waste disposal apparatus 6.

If an abnormality occurs in the dilution step, for example, if the state of “no load” does not change even after the predetermined time has passed even though the operation of the dilution tank 30 has been started, the determination unit 51 performs the dilution step. It is determined that an abnormality has occurred in. Specifically, it is conceivable that the mixture M may have clogged in the discharge path 11 on the upstream side of the dilution tank 30. In this case, the control unit 50 repeats the opening and closing of the first on-off valve 12 on the upstream side of the dilution tank 30 a predetermined number of times in a state where the second on-off valve 16 of the drainage channel 15 on the downstream side of the dilution tank 30 is closed. Execute After that, when the control unit 50 confirms that the abnormal state of the dilution tank 30 has been resolved, the normal operation of the dilution tank 30 is restarted. On the other hand, if the abnormal state of the dilution tank 30 has not been eliminated, the control unit 50 causes the notification unit 53 to notify that the abnormality has occurred in the dilution process, and stops the entire waste disposal apparatus 6.

In the dilution step, when the state of “dilution process” does not change even after the lapse of a predetermined time, the control unit 50 determines that the dilution is not sufficient, and performs control to additionally supply water from the discharge unit 14. Execute. The supply amount of the water to be additionally supplied is determined based on the measurement value of the third measurement unit 30D at the time when the dilution is determined to be insufficient. That is, the determination unit 51 determines the state of the dilution tank 30 (the degree of progress of the dilution process) based on the value of the current consumption of the motor 30A measured by the third measurement unit 30D. The control unit 50 determines the supply amount of water to be resupplied from the discharge unit 14 based on this.

In the dilution step, when the state of “dilution process” does not change even after the predetermined time has passed even though water is resupplied, the determination unit 51 determines that accumulation of dirt has occurred in the dilution tank 30 ( It is determined that “cleaning is required”). In this case, the control unit 50 stops the operation of the dilution tank 30 and executes the cleaning mode of the dilution tank 30. In the washing mode of the dilution tank 30, the control unit 50 supplies water from the discharge unit 14 in a state where the first opening / closing valve 12 of the discharge passage 11 is open and a state where the second opening / closing valve 16 of the drain passage 15 is closed. At the same time, while the processing agent is being injected from the processing agent input section 23, the control for repeating the forward rotation and the reverse rotation driving of the motor 70A of the mixer 70 and the motor 30A of the dilution tank 30, respectively, is executed. The processing agent supplied in the cleaning mode is only the processing agent containing calcium acetate supplied from the first processing agent supply section 23A. Thereafter, the control unit 50 keeps the state until the dilution tank 30 is in the “diluted” state, that is, the state in which the magnitude of the current consumption of the motor 30A measured by the third measuring unit 30D is not equal to or more than the second predetermined value. The motor 70A and the motor 30A are driven until the operation is completed. While the cleaning mode of the dilution tank 30 is being executed, the control unit 50 notifies the notification unit 53 that the cleaning mode of the dilution tank 30 is being executed. When the control unit 50 confirms that the state of the dilution tank 30 is in the state of “diluted”, the control unit 50 stops the notification by the notification unit 53. On the other hand, if the abnormal state of the dilution tank 30 is not resolved, the control unit 50 notifies the notification unit 53 of the fact and stops the entire waste disposal apparatus 6.

When an abnormality occurs in the separation process, for example, when the operation of the separation unit 40 is started and there is no change after a lapse of a predetermined time from the “no load” state, the determination unit 51 determines that the abnormality is It is determined that an error has occurred. Specifically, it is conceivable that the diluent T may have clogged in the drainage channel 15 on the upstream side of the separation unit 40. In this case, the control unit 50 executes control to repeat opening and closing of the second on-off valve 16 a predetermined number of times while operating the separation unit 40. Meanwhile, the control unit 50 causes the notification unit 53 to notify that an abnormality has occurred in the separation process. Thereafter, when the control unit 50 confirms that the abnormal state of the separation unit 40 has been resolved, the normal operation of the separation unit 40 is restarted. On the other hand, when the abnormal state of the separation unit 40 has not been eliminated, the control unit 50 causes the notification unit 53 to notify that the abnormality has occurred in the separation process, and stops the entire waste disposal apparatus 6.

In the separation step, if the state of the separation unit 40 does not change from the state of “separation processing” to the state of “no load” within a predetermined time, the determination unit 51 determines that accumulation of dirt in the separation unit 40 has not occurred. It is determined that the occurrence has occurred (determined as "needs cleaning"). In this case, the control unit 50 executes the cleaning mode of the separation unit 40. In the cleaning mode of the separation unit 40, the control unit 50 controls the supply of water from the discharge unit 14 and the input of the treatment agent with the first on-off valve 12 of the discharge path 11 and the second on-off valve 16 of the drainage path 15 opened. While the processing agent is supplied from the unit 23, control is performed to repeat the forward rotation and the reverse rotation of the motor 70 A of the mixer 70, the motor 30 A of the dilution tank 30, and the motor 40 C of the separation unit 40, respectively. The processing agent supplied in the cleaning mode is only the processing agent containing calcium acetate supplied from the first processing agent supply section 23A. Thereafter, the control unit 50 controls the

motors

70A and 70A until the separation unit 40 is in the “no load” state, that is, until the magnitude of the current consumption of the motor 40C measured by the fourth measurement unit 40F is not a predetermined value or more. The motor 30A and the motor 40C are each driven. During the execution of the cleaning mode of the separation unit 40, the control unit 50 causes the notification unit 53 to notify that the cleaning mode of the separation unit 40 is being executed. When the control unit 50 confirms that the state of the separation unit 40 has become “no load”, the control unit 50 stops the notification by the notification unit 53. On the other hand, when the abnormal state of the separation unit 40 is not eliminated, the control unit 50 notifies the notification unit 53 of the fact and stops the entire waste disposal apparatus 6.

As described above, at the time of execution of each processing by the processing unit 90, the waste disposal apparatus 6 performs the second processing after a predetermined time has elapsed from the start of the processing in any of the crushing unit 20, the mixer 70, the dilution tank 30, and the separation unit 40. When the measurement values of the first measurement unit 20H, the second measurement unit 70B, the third measurement unit 30D, and the fourth measurement unit 40F are different from the assumed values, the control unit 50 performs processing based on the difference between the measurement values and the assumed values. At least one of the additional introduction of the agent and the additional supply of water is executed.

The control unit 50 executes a control to notify the operating unit 53 of the operation status while the waste disposal apparatus 6 is processing the paper diaper Dd. In the case of the present embodiment, the control unit 50 determines that the operation status of the processing unit 90 is normal if the processing by the processing unit 90 is normal in addition to the abnormality content at the time of occurrence of the abnormality as described above as the operation status of the waste disposal apparatus 6. , The current process, and the time to the end are notified to the notifying unit 53. The control unit 50 causes the storage unit 54 to store information regarding various operating states of the waste disposal apparatus 6 as data, and causes the transmission unit 55 to transmit the information externally.

Next, prediction of the state of the processing unit 90 by the control unit 50 will be described. As described above, in each unit of the processing unit 90, the motor load varies according to the degree of progress of the process from the start to the end of the process. FIG. 9 shows the relationship between the number of times of processing (horizontal axis) and the load reduction time (vertical axis) of the motor 70A when processing the disposable diaper Dd as an object to be processed in the mixer 70 as each unit of the processing unit 90. I have. The load reduction time is a time from when the processing is started in each unit of the processing unit 90 until the current consumption value of the motor, which has risen once, decreases to a predetermined value. In the case of the mixer 70, the current consumption value of the motor 70A decreases as the reaction between the polymer and the processing agent progresses. The current consumption value of the motor 70A decreases to a predetermined value or less within a predetermined time when a normal process is performed in the mixer 70. However, if dirt accumulates or some abnormality occurs, the load on the motor 70A does not decrease to a predetermined value within a predetermined time. In this case, the subsequent normal processing may not be performed. For this reason, in the present embodiment, the control unit 50 acquires the load reduction time as the information on the operation state based on the information on the operation state measured by the measurement unit, measures the load reduction time, and stores it in the storage unit 54. The control unit 50 predicts the future state of the mixer 70 based on the past load reduction time stored in the storage unit 54 while storing the same. That is, the control unit 50 obtains the load reduction time based on the magnitude of the current consumption of the motor 70A measured by the second measuring unit 70B as an information obtaining unit that obtains information on the operation state of the processing unit. The determination unit 51 determines the state of the processing in the mixer 70 based on the load reduction time as information on the operation state of the processing unit. Further, the determination unit 51 predicts the processing status of the mixer 70 based on the past load reduction time stored in the storage unit 54.

Specifically, when the processing is completed by the mixer 70, the control unit 50 acquires the load reduction time based on the current consumption value of the motor 70A measured by the second measurement unit 70B, and stores the load reduction time in the storage unit 54. A regression analysis is performed by linear regression on the measured values of a plurality of recent times (for example, 10 times) of the past load reduction times, and the upper limit value is exceeded within several times (for example, 20 times). Predict whether or not. In the case of FIG. 9, when the regression analysis is performed by linear regression on the last ten load reduction times including the newest measured value Mv, it is predicted that the upper limit will be exceeded within 20 times (18 times). When such a prediction result is obtained, the determination unit 51 determines that the situation requires the cleaning of the mixer 70. In this case, the control unit 50 executes the cleaning mode of the mixer 70. At this time, the control unit 50 causes the notification unit 53 to execute notification.

The prediction of the state of the processing unit 90 by the determination unit 51 can be similarly performed not only in the mixer 70 but also in the crushing unit 20, the dilution tank 30, and the separation unit 40. In the case of the crushing unit 20, it is possible to determine whether the load reduction time acquired based on the current consumption value of the motor 20G measured by the first measuring unit 20H is within a predetermined range, and to determine the load acquired in the past. By performing a regression analysis on the numerical values for the latest plurality of times in the reduction time, it is possible to predict whether or not the upper limit value is exceeded within a predetermined number of times. In the case of the dilution tank 30, it is possible to determine whether or not the load reduction time acquired based on the current consumption value of the motor 30A measured by the third measuring unit 30D is within a predetermined range, and to determine the load acquired in the past. By performing a regression analysis on the numerical values for the latest plurality of times in the reduction time, it is possible to predict whether or not the upper limit value is exceeded within a predetermined number of times. In the case of the separation unit 40, it is possible to determine whether the load reduction time acquired based on the current consumption value of the motor 40C measured by the fourth measurement unit 40F is within a predetermined range, and to determine the load acquired in the past. By performing a regression analysis on the numerical values for the latest plurality of times in the reduction time, it is possible to predict whether or not the upper limit value is exceeded within a predetermined number of times.

For example, as illustrated in FIG. 10, the prediction of the state of the processing unit 90 by the determination unit 51 includes, as information on the operating state, the first measurement unit 20H, the second measurement unit 70B, the third measurement unit 30D, and the fourth measurement unit 30D. By performing regression analysis by linear regression on the current consumption value measured by the measurement unit 40F and the measured values of the power consumption values of the latest multiple times (for example, 10 times), within several times (for example, 20 times) It is also possible to predict whether or not at least one of the upper limit value and the lower limit value will be exceeded.

As described above, the waste disposal apparatus 6 according to the sixth embodiment of the fourth waste disposal apparatus determines the state of the disposable diaper Dd as the processing object input from the input unit 10, and performs processing based on the determined state. Determine the dosage of the agent. Therefore, an appropriate amount of the treatment agent can be easily grasped.

Therefore, the waste disposal apparatus 6 of Embodiment 6 of the fourth waste disposal apparatus can suppress the occurrence of trouble due to excess or deficiency of the treatment agent.

As described above, the waste disposal apparatus 6 according to the sixth embodiment of the fifth waste disposal apparatus has the first measurement unit 20H, the second measurement unit 70B, the third measurement unit 30D, and the control unit 50 as the information acquisition unit. And the current consumption values of the

motors

20G, 70A, 30A, and 40C of the respective units (the crushing unit 20, the mixer 70, the dilution tank 30, and the separation unit 40) measured by the fourth measuring unit 40F. . This consumed current value is stored in the storage unit 54. The determination unit 51 determines the state of the processing unit 90 based on the current consumption value as information on the operating state of the processing unit 90 acquired by the control unit 50. As described above, since the state of the processing unit 90 is determined by the determination unit 51, it is possible to reduce the variation in the determination result as compared with the case where the operator determines.

Therefore, the waste disposal apparatus 6 of the sixth embodiment of the fifth waste disposal apparatus can more accurately grasp the status of the processing unit 90.

The waste disposal apparatus 6 according to the sixth embodiment of the fourth waste disposal apparatus includes a treatment agent input section 23 that inputs a processing agent into the processing section 90 and a measurement section 52 that measures the number of disposable diapers Dd input from the input section 10. And The determination unit 51 determines the state of the paper diaper Dd based on the measurement result of the measurement unit 52. The control unit 50 causes the processing agent input unit 23 to input the determined input amount of the processing agent. For this reason, the number of disposable diapers Dd can be measured by the measuring unit 52 immediately after the dispensing, so that the state can be quickly determined. The control unit 50 causes the processing agent input unit 23 to input an appropriate amount of the processing agent based on the determination result. As a result, the processing agent can be promptly and appropriately charged to perform the processing.

In the waste disposal apparatus 6 of the sixth embodiment of the fourth waste disposal apparatus, when the control unit 50 detects the shortage of the amount of the processing agent that can be injected with respect to the determined injection amount, The operation of the processing unit 90 is stopped. For this reason, it is possible to prevent the treatment agent in a state capable of absorbing moisture and the polymer that has not reacted to be discharged.

The waste disposal apparatus 6 according to the sixth embodiment of the fourth waste disposal apparatus is provided with a notification unit 53 that reports information on the operation status of the waste disposal apparatus 6. Therefore, it is possible to assist the user in easily grasping the operation status of the waste disposal apparatus 6.

The waste disposal apparatus 6 according to the sixth embodiment of the fourth waste disposal apparatus includes a storage unit 54 for storing information on the operation status of the waste disposal apparatus 6. For this reason, the user can be easily notified of the past operation status.
