JP 2003-340495 A

  However, in the above-mentioned conventional ones, it is common for a plurality of users to throw in the garbage as needed, and the amount and frequency of one-time charge also vary depending on the usage form. For this reason, for example, it was difficult to grasp the input amount per day.

  Therefore, even if the input amount is excessive relative to the scale, it is difficult to grasp this, which causes the decomposition solution concentration to increase, leading to a decrease in decomposition capability, and other devices such as garbage input devices. There was a problem of causing a burden and causing a failure.

  The present invention has been made in view of the above-mentioned problems, and the object of the present invention is to convert the amount of garbage input and inform the input person of this, so that the amount of garbage exceeding the processing capacity is input. It is an object of the present invention to provide a method for monitoring and controlling the amount of garbage input in an underwater decomposition-type garbage disposal apparatus capable of preventing the degradation or failure caused by decomposition and preventing the garbage from being decomposed stably.

  In order to achieve the above object, a method for monitoring and controlling the amount of garbage input in the underwater decomposition type garbage processing apparatus according to the first aspect of the present invention provides a method for monitoring the amount of garbage input to the garbage input device with the garbage input device. After being crushed, it is introduced into the decomposition tank, and the decomposition liquid stored in the decomposition tank is sprayed onto the liquid surface of the decomposition liquid by a circulation pump and circulated while being decomposed by microorganisms in this decomposition liquid. The apparatus is characterized in that an amount of garbage input to the garbage input device is estimated based on an operation time in the garbage input device, and the amount of food input is displayed on a display device.

  The method for monitoring and controlling the amount of garbage input in the underwater decomposition type garbage processing apparatus according to the second aspect of the present invention is the current value of the garbage input device as the operating time elapses when the garbage input device is activated. Whether or not the vehicle is operating normally is determined based on the change in the error, and if not normal, an error is displayed.

  According to the present invention, each input person can easily grasp the input amount even when a plurality of input persons input garbage, thereby preventing degradation of decomposition ability due to excessive input. At the same time, it is possible to prevent the failure of other devices such as the garbage throwing device, and to achieve a stable decomposition process of the garbage.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a schematic configuration of an underwater decomposition type garbage disposal apparatus of the present invention.

  In FIG. 1, reference numeral 1 denotes a garbage input device, which includes a hopper 11 that inputs food waste and a disposer 12 that crushes the input food waste, and the food waste crushed by the disposer 12 is introduced into the introduction pipe. 13 is introduced into the decomposition tank 2. The hopper 11 is provided with an open / close lid 11a so as to be freely opened and closed.

  The decomposition tank 2 decomposes garbage, and stores a decomposition solution containing microorganisms that treat the garbage.

  The decomposition tank 2 is provided with a stirrer 3, a circulation pump 4 and a diffusion member 5.

  In the agitator 3, a stirring blade 33 provided on the rotation shaft 32 is rotatably provided by the rotation of the motor 31, and a flow for guiding the decomposition liquid stored in the decomposition tank 2 downward by the rotation of the stirring blade 33. It is generated and stirred by this flow so that the entire decomposition solution becomes homogeneous.

  The circulation pump 4 is disposed at the bottom of the decomposition tank 2 and sucks the decomposition liquid in the decomposition tank 2 and supplies it to the diffusion member 5. One end of a supply pipe 41 is provided on the discharge port side. Are connected. A supply port 41 a serving as the other end of the supply pipe 41 is disposed above the diffusion member 5, and a decomposition solution is sprayed from the supply port 41 a to the diffusion member 5.

  The diffusion member 5 is for diffusing the decomposition solution injected from the supply port 41a in the upper space, and oxygen is supplied into the decomposition solution by this diffusion to activate the activity of microorganisms. In other words, garbage is decomposed by aerobic microorganisms.

  Then, a circulating flow is generated in the decomposition liquid in the decomposition tank 2 by the downward water flow generated by the stirrer 3 and the water flow generated by suction of the circulation pump 4, and supply of the decomposition liquid to the liquid surface from the injection port 41a. In combination with the above, the entire decomposition solution is sufficiently stirred and homogenized. Thereby, the decomposition process by the microorganisms of a decomposition solution can be performed efficiently in a favorable state.

  On the other hand, a return pipe 42 is branched from the middle of the injection pipe 41, and through the return pipe 42, a part of the decomposition liquid is generated by opening and closing a supply valve 43 provided in the return pipe 42. It is made to return to the garbage input apparatus 1 (disposer 12).

  That is, by returning the decomposed liquid to the disposer 12 through the return pipe 42, the raw garbage introduced into the garbage input device 1 and crushed is introduced into the decomposition tank 2 through the introduction pipe 13 together with the decomposed liquid.

  Further, a drying device 6 is connected to the decomposition tank 2. The drying device 6 is for periodically extracting and drying residues and the like contained in the decomposition solution of the decomposition tank 2, and is connected through the branch pipe 61 by branching a branch pipe 61 to the injection pipe 41. ing. The branch pipe 61 is provided with two on-off valves 61a and 61b, and a circulation pipe 61c connected to the decomposition tank 2 is connected between the on-off valves 61a and 61b.

  Normally, by opening the on-off valve 61a and closing the on-off valve 61b, a part of the decomposition liquid is circulated to the decomposition tank 2 through the branch pipe 61 and the circulation pipe 61c. By closing 61 a and opening the on-off valve 61 b, the decomposition liquid accumulated during this period is introduced into the drying device 6.

  In other words, the drying device 6 does not draw a large amount of decomposition solution at a time from the viewpoint of capacity and performs drying, but periodically draws an amount corresponding to the volume and performs drying. , 61b is set so that the amount of the decomposing liquid collected in the branch pipe 61 corresponds to this amount. In this way, by extracting a part of the decomposition solution and drying it with the drying device 6, the concentration of the decomposition solution in the decomposition tank 2 such as salt content is adjusted in combination with the water supply by the water supply means described later.

  Moreover, the hot air which contributed to the drying in the drying device 6 is guided to the upper space of the decomposition tank 2 through the hot air pipe 62 by an exhaust blower (not shown). This hot air is used to maintain an appropriate temperature of about 40 ° C. at which the decomposition solution is activated. In addition to the hot air, the decomposition heat of microorganisms and the driving heat of the circulation pump 4 are also used to maintain the temperature of the decomposition solution. Has contributed.

  Further, the decomposition tank 2 is provided with a water supply means (not shown) for supplying water to the decomposition liquid, and decomposes by appropriately supplying water by the water supply means as the decomposition liquid is drawn into the drying device 6. In addition to adjusting the concentration of the liquid salt, etc., the water level of the decomposition solution is adjusted.

  Next, garbage processing by the underwater decomposition type garbage processing apparatus configured as described above will be described.

  First, garbage generated in a kitchen or the like is put into a hopper 11 of the garbage throwing device 1 and crushed by a disposer 12. The crushed garbage is introduced into the decomposition tank 2 through the introduction pipe 13 together with the decomposition liquid introduced into the garbage input device 1 through the injection pipe 41 and the return pipe 42 by the circulation pump 4.

  In the decomposition tank 2, the introduced garbage is decomposed by microorganisms in the decomposition solution. At this time, the decomposition liquid is sprayed on the liquid surface by injecting the decomposition liquid from the injection port 41a through the injection pipe 41 to the diffusion member 5 by the circulation pump 4, thereby supplying oxygen into the decomposition liquid. .

  In addition, the decomposition liquid is maintained at an appropriate temperature by supplying hot air from the drying device 6, and a circulation flow is generated in the decomposition liquid by the stirring action by the stirrer 3 and the suction action of the decomposition liquid by the circulation pump 4. The decomposition solution is sufficiently stirred to make it homogeneous.

  Therefore, the decomposition solution is in a state in which the activity of the microorganism is activated by these actions, and thereby the garbage can be efficiently decomposed.

  Further, in the drying device 6, the residue of the decomposition solution is periodically drawn and dried according to the amount of garbage put into the decomposition tank 2, and decomposed by drawing the decomposition solution into the drying device 6. When the liquid level drops, water is supplied from the water supply means as needed.

  And in the underwater decomposition | disassembly type garbage processing apparatus which performs the above garbage processing, monitoring control of the garbage input amount which throws in garbage is performed.

  In this monitoring control, the input amount is estimated based on the operation (operation) time associated with the number of activations of the garbage input device 1 (disposer 12), and this result is displayed on a display device described later. .

  2 and 3 are flowcharts showing a specific example of the monitoring control.

  First, when throwing garbage into the garbage throwing device 1, in step S1, the open / close lid 11a is opened to throw in garbage, and after the throw, the open / close lid 11a is closed.

  Next, when the start switch is turned on in step S2, the count is initialized in step S3.

  In step S4, it is determined whether the opening / closing lid 11a is opened or closed. If the opening / closing lid 11a is closed, the process proceeds to step S5. If the opening / closing lid 11a is opened, the process returns to step S2. In addition, when the opening-and-closing lid 11a is opened, it sets beforehand so that the operation | movement of the garbage throwing-in apparatus 1 may stop from a safety surface.

  In step S5, the supply valve 43 is opened and the decomposition liquid is supplied (returned) to the disposer 12 through the return pipe 42. The disposer 12 is activated after a predetermined time T1 seconds have elapsed, and the process proceeds to step S6 after a predetermined time T2 seconds has elapsed. . Thereby, the crushed processing of the input garbage accompanying supply of a decomposition solution will be performed.

  In step S6, it is determined whether the opening / closing lid 11a is opened or closed. If the opening / closing lid 11a is closed, the process proceeds to step S7. If the opening / closing lid 11a is opened, the operation of the disposer 12 is stopped in step S8. 43 is closed to stop the supply of the decomposition liquid, and the process returns to step S2.

  In step S7, it is determined whether the current value due to the operation of the disposer 12 is equal to or greater than a predetermined current value. If it is equal to or greater than the predetermined current value, after counting in step S10, it is determined in step S11 whether the predetermined time T3 seconds have elapsed after the predetermined time T2 seconds have elapsed in step S5, and if the predetermined time T3 has elapsed. In step S12, the supply valve 43 is closed and the process proceeds to step S13. If the predetermined time has not elapsed, the process skips step S12 and proceeds to step S13.

  In step S13, it is determined whether or not a preset time T4 seconds has elapsed. If the time T4 seconds has not elapsed, the process returns to step S6.

  Here, in normal operation, as shown in FIG. 4, it is known in advance that when the disposer 12 is operated and a predetermined time T3 seconds elapses, the crushing process of the input garbage is finished and the current value becomes equal to or lower than the predetermined current value. . Accordingly, normally, when the predetermined time T3 seconds elapses, the supply valve 43 is closed in step S12, and when the process returns to step S7 through steps S13 and S6, the process proceeds to step S14. In other words, the predetermined time T3 is set in advance as the time that is normally crushed by the input of garbage. Moreover, the current value when food waste is normally crushed is set in advance as a predetermined current value (for example, about 2.7 A).

  On the other hand, if the time T4 has elapsed in step S13, it is timed out and the process proceeds to step S15 to display an error. That is, the state where the current value of the disposer 12 does not fall below the predetermined current value continues for the time T4 even though the supply valve 43 is closed after the predetermined time T3 has elapsed. Confirms the error display and opens the open / close lid 11a to check whether the disposer 12 is blocked.

  In step S14, it is determined whether the supply valve 43 is open or closed. If the supply valve 43 is closed, the process proceeds to step S16. If the supply valve 43 is open, the process proceeds to step S17 and an error is displayed. That is, this is a case where the current value of the disposer 12 becomes equal to or lower than the predetermined current value even though the predetermined time T3 has not elapsed. In this case, the operator confirms the error display and disassembles the current value into the disposer 12. Check that the liquid supply is not stopped due to blockage by opening the lid 11a.

  In addition, after checking in step S15 and step S17, it restarts. That is, the control similar to the above is performed by returning to step S1 in a state where the garbage is not thrown in.

  And when crushing with the disposer 12 accompanying the input of garbage is completed, in step S16, the amount of garbage input is estimated based on the count value added in step S10 (this corresponds to the operating time), The input amount is recorded along with the time, and the process proceeds to step S18. In step S18, the supply valve 43 is closed to stop the supply of the decomposition liquid to the disposer 12, and the operation of the disposer 12 is stopped in step S19.

  Thereafter, if the sum of the estimated amounts of waste input in step S20 exceeds 60 kg, for example, an overload warning is displayed, and if it is 60 kg or less, the warning is reset. The daily input amount for displaying the warning is set in advance according to the scale of the apparatus.

  5 and 7 show specific display examples by the display device that displays the input amount of the garbage estimated as described above.

  Fig. 5 shows a display example for one day, Fig. 6 shows a week, and Fig. 7 shows a display example for three months. By using this display device, it is possible to quickly grasp the input amount such as a child every day. Can do. Moreover, each data of the desired amount of garbage input can be seen by operating a screen or a keyboard.

  In this way, by roughly calculating the amount of garbage input based on the operating time of the disposer and displaying it on the display device, each input person can, for example, per day The input amount can be easily grasped. As a result, it is possible to prevent degradation of the decomposition capacity due to excessive input, and it is possible to prevent failure of other devices such as a garbage input device (disposer), and to achieve stable decomposition processing of food waste. it can.
