Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to human waste treatment for treating human waste outdoors without a purification treatment facility, in transportation facilities such as ships and trains, and in tunnels where the vacuum car cannot enter because it is closed from the surrounding area. The present invention relates to an apparatus, and more particularly, to a processing capacity detection mechanism for an excrement processing apparatus, which is provided with a liquid level detection means for detecting the liquid level of the excrement stored in a container for drying.

[0002]

2. Description of the Related Art In the general household, human waste discharged from a human body is usually discharged into a sewer by a flush toilet or the like, or temporarily stored in a septic tank to be purified and then discharged into a river. However, when an event is held outdoors, for example, at a venue where a large number of staff members such as an athletic meet, a trade fair, and a gathering gather, the physiological phenomenon of participants has conventionally been eliminated by providing a temporary toilet.

In the conventional treatment of human waste in the open air or in a place where there is no purification facility, a movable temporary toilet has been used. However, most of them have a structure that has a toilet bowl for temporarily storing human waste, and the human waste excreted from the human body is stored in this toilet tank. Therefore, after using the temporary toilet, the human waste stored in the toilet tank must be collected by a vacuum car or the like and transferred to the human waste treatment facility. For this reason, post-treatment after collection is required, and the post-treatment of human waste is troublesome and unhygienic.

Further, in a transportation system such as a train, a bus or a ship which travels a long distance, a dedicated tank for storing excreted excrement is provided, and the excrement is treated with a chemical or the like to store the excrement. After carrying out the procedure, it was common to collect it with a vacuum car at the terminal station or relay point.

As described above, in the conventional treatment of human waste in a temporary toilet or a movable transportation facility, most of the waste is stored as excreted from the human body and then collected. Therefore, it must be said that any of the storage method, the collection method, and the treatment method is non-modern and extremely unsanitary. Therefore, when the temporary toilet is used for a long time, the excreted excrement remains in the tank, which causes an offensive odor. In addition, since the treatment work after use is disliked by the workers, it is not preferable from the viewpoint of modernization of maintenance after the temporary toilet is installed.

[0006] and from this situation, how to handle the hygienic human waste than conventional has been considered various. For example, there is a method of sterilizing and deodorizing by adding chemicals together with human waste. This method is often used for transportation such as Shinkansen, but it has drawbacks that it cannot be used for a long period of time because the medicine circulates in the tank, and the cost of using the medicine becomes high.

[0007] Further, a method of preventing the emission of odor by storing and packing human waste in a bag made of vinyl or the like has been considered. However, a plastic bag having a considerably large area must be used for each excretion, and the processing cost becomes high, and the processing for separating human waste from the plastic bag at a later time is troublesome and the processing facility becomes large. It was a thing.

Further, a method of directly drying the excreted excrement with a heating power such as a burner has been considered. However, since most components of human waste are water, much energy was required to remove this water.
In addition, in the conventional method of simply performing a drying process with heat, a single processing time is long.

Therefore, the same inventor as the applicant of the present application is
We have proposed a human waste treatment device in which a rotating stirring blade is provided in a container for storing human waste, and a large number of heat storage bodies are stored in the container. With this device, by heating the container from the outside and simultaneously rotating the stirring blade, the human waste can be quickly dried, and the water, which is a major component of human waste, can be evaporated (Japanese Patent Application No. 124150/1988). Etc.).

Utilizing this newly proposed human waste treatment device
Then, the excreted excrement is heated and evaporated in the container,
Most of the water is evaporated and released into the atmosphere.
In this case, the diffused water vapor is deodorized with a catalyst, etc.
It seems that the house is standing up and many people are gathering.
Even if it's a strange placeNothing
It was also preferable from the viewpoint of environmental protection.

[0011]

It is extremely hygienic to evaporate and dry the human waste in such a sealed container, and since the work can be systematized, it does not burden the worker. It is a thing. The human waste treatment device proposed by the present inventor has a configuration in which human waste is stored in a closed container (drying pot) and the lower portion of the drying pot is heated. With this configuration, the drying pot and the toilet bowl are connected by a pipe or the like so that the excreted human waste collected from the toilet bowl can flow into the drying pot. Then, the excreted excrement is dried in a drying pot so that the volume thereof can be made extremely small. In this drying process, a drying cycle is set from the input of a fixed amount of human waste to the completion of all the drying, and the process is carried out periodically as long as the user continues.

However, since the drying process is periodically performed, the size (volume) of the drying pot is limited, and it is impossible to temporarily dry a large amount of excrement. That is, the processing capacity is improved by increasing the volume of the drying pot, but it is intended to prevent the energy loss from increasing during standby or when processing a small number of people. For this reason, the volume of each drying pot is designed according to its use, and the number of users and the amount of excrement that can be handled within a predetermined time are limited.

However, in some cases, more excrement than the preset processing capacity is put into the drying pot. The reason why such overloaded excrement is thrown in may be that a large number of users use the toilet in a short period of time or that waste other than human waste is thrown into the toilet. Thus, when the amount of excrement exceeding the ability to normally dry is put into the drying pot, the drying cycle is not performed smoothly.

That is, when the excrement having a processing capacity or more is put into the drying pot, the excrement is filled up to a high position of the drying pot, and a part of the human waste remains as it is without being dried.
It was a cause of dirt in the drying pot. In addition, only whether the burden to a heat source such as a heater, had also become a remote cause of the failure. Therefore, in order to smoothly perform the drying cycle of the excrement, it is preferable to limit the amount of excrement to be dried in one cycle to a predetermined value or less and to keep the drying cycle constant. Further, if the drying pot is filled with excrement, the time for one drying cycle becomes long, and the toilet cannot be used until the drying cycle is completed. Then you will not be able to use the temporary toilet during that cycle,
It was also inconvenient for the users.

From the above, the amount of excrement to be put into the drying pot is strictly measured, and the drying cycle in the drying pot is kept within the set value, so that the excrement amount exceeding the processing capacity of the drying pot is obtained. It was desired to have a mechanism for controlling so as not to turn on.

Next, the operation of this embodiment will be described.

<Stand-by operation>

Before using the human waste treatment device 5 to perform the human waste drying process, the device must be held in a standby state.

When using the device, first turn on the power switch 8
9 is turned on and the central processing control circuit 84 is activated to transmit the instruction to the whole human waste processing apparatus 5. The central processing control circuit 84 outputs a signal to the heater control circuit 94,
The heater 35 and the reheating heater 36 are energized to heat the recovery box 15 and the inside of the reheating box 17. At the same time, the motor control circuit 91 also outputs a signal, and the motor 4
4 is driven, and the air pressure-fed by the fan 45 is transmitted to the ejector 19 via the blower pipe 29. However, the other motor 40 remains stopped, and the drive mechanism 14 also stops. Further, the valve control circuit 92 closes the open / close valve 25 and opens only the open / close valve 26.

[0049] In this state, when the air from the blower 23 passes through the ejector 19. In high speed, in the ejector 19
The inside of the catalyst box 18 connected to the central portion has a negative pressure, and the air in the catalyst box 18 is sucked to the outside. Then, ejector 1
Due to the negative pressure generated by the air passing through 9, the moving path of the air flowing through the blower 22, the blower pipe 24, the open / close valve 26, the blower pipe 28, the reheating box 17, and the catalyst box 18 which are stopped is formed. It Therefore, the air flowing in from the outside is heated by the reheating heater 36 of the reheating box 17, and the hot air flows through the catalyst 38 to warm the catalyst 38. This is because the catalyst 38 does not undergo any redox at low temperature, and it is necessary to raise the temperature of the catalyst 38 to a certain temperature in advance for the deodorizing effect .

The series of standby operations are continuously operated until the processing switch 87 is pressed.

<Introduction of human waste>

If the above-mentioned human waste processing apparatus 5 is kept in a standby state, the temporary toilet 1 can be used. When using this temporary toilet 1, the user can open the door 4, enter the house 3, and excrete large and small urine in the toilet 6. Then, after using this temporary toilet 1, it must be cleaned for the user who will use the temporary toilet 1 next time. In this embodiment, the instruction is given manually to clean the toilet bowl 6, and the user presses the processing switch 87 after using the toilet bowl 6. When the processing switch 87 is pressed, human waste is allowed to flow into the drying kettle 10. First, when the processing switch 87 is pressed after using the toilet 6,
The dry processing instruction circuit 88 transmits the signal to the central processing control circuit 84, and the central processing control circuit 84 transmits the signal to the shutter control circuit 90. Then, the shutter plate 47 in the shutter 12 is pivoting, to open the bottom of the toilet 6. Therefore, the human waste accumulated in the bottom of the toilet bowl 6 is dropped onto the introduction pipe 11, and at the same time, the valve mechanism 13 is opened by the instruction of the shutter control circuit 90, and the human waste is dried along the inclined surface of the introduction pipe 11 in the drying pot. It is made to flow into 10.

After the shutter 12 and the valve mechanism 13 are opened by the shutter control circuit 90 for a certain period of time, the respective mechanisms are closed and the electrical connection between the toilet 6 and the drying pot 10 is blocked. This is to prevent the malodor generated from the drying pot 10 from flowing out to the toilet bowl 6 side by closing the drying pot 10 airtightly.

<Treatment of evaporation and drying>

Next, in conjunction with the operation of the shutter 12 and the valve mechanism 13, the heater control circuit 94 instructs the heater 31 to supply an electric current, and the heater 31 heats the bottom and the periphery of the drying pot 10. . By the heating by the heater 31, the temperature of the human waste in the drying pot 10 is raised to the boiling point. Then, the valve control circuit 92 causes the open / close valve 2
6 is closed and at the same time the on-off valve 25 is opened. Even if the opening / closing valves 25 and 26 are switched, the output of the motor control circuit 91 does not change and the motor 40 of the blower 22 is not driven. Therefore, as described above, the air sucked by the ejector 19 is the blower 22, the blower pipe 24, the open / close valve 25, the blower pipe 27, the nozzle 4 that is stopped.
2, the drying cauldron 10, the exhaust pipe 20, a dust collector 16, reheating box 17, and more fluid in the path of the catalyst box 18, the circulation circuit of the air is formed. By this air path, air is constantly supplied from the nozzle 42 to the inside of the drying cauldron 10 and acts to assist the oxidation of heated human waste.

Then, the motor control circuit 91 operates the motor in the drive mechanism 14 to rotate the rotary shaft 32, whereby the stirring blade 33 rotates at the bottom portion of the drying pot 10. At this time, the plurality of heat storage bodies 34 are rotated at the bottom of the drying pot 10 by the stirring blades 33, and have a function of stirring the stored human waste. For this reason, the human waste is mixed so as to have a uniform temperature, and the heat stored in the heat storage body 34 is transferred from the surface to the human waste around it to heat the human waste. Heat storage body 34
Since its surface is spherical and has a large surface area, the heating rate of human waste is increased.

Thus, the heat of the heater 31 evaporates the water in the human waste that has evaporated in the drying kettle 10 into water vapor, which vaporizes, and this water vapor moves to the dust collector 16 together with air from the exhaust pipe in the upper portion of the drying kettle 10. . This dust collector 16
Among the pipes a double, air containing water vapor is pivoted at high speed to support <br/> cyclone-shaped, the dust contained in the air falls, is separated and the air and dust . The separated dust is stored in the recovery box 15 at the bottom of the dust collector 16, but some water remains in the dust. However, the water contained in this dust is
Is evaporated again by the heat of and the evaporated water vapor is collected by the dust collector 1.
It flows into the reheating box 17 from the pipe 39 in the center of 6. Further, the water temperature by flowing the dust collector 16 is condensed drops likewise is evaporated again in the recovery box 15. Since the air is constantly sucked in the direction of the reheating box 17 due to the negative pressure generated in the ejector 19 from the standby state, the vapor containing the vapor and the malodor evaporated from the drying kettle 10 and the collection box 15 is removed. It flows into the reheating box 17. The steam and air are used by the reheat heater 3 in the reheat box 17.
In contact with 6, the catalyst 38 is raised again to a temperature sufficient to effect oxidation. After that, the steam and the air pass through the filter 37, come into contact with the catalyst 38, and the malodorous components contained in the steam and the air are oxidized and decomposed, so that the malodorous components are transformed into odorless components. Then, the water vapor and air are sucked by the ejector 19 and diffused to the outside. With such an air path inside the human waste treatment device 5,
The water content of the human waste in the drying pot 10 is successively dried and diffused into the atmosphere.

<Detection of liquid level in the drying pot 10>

As described above, the human waste from the toilet 6 is dried in the kettle 10
It is thrown into the inside, but this thrown human waste is sequentially put in.
Then , the liquid level in the drying pot 10 rises to a certain level. Inside the drying pot 10, two liquid level detecting means 5 are provided.
0, 51 are installed, and when the power switch 89 is turned on, a positive potential is applied to each contact detection rod 63, 64 immediately. Then, the main body of the drying pot 10 is grounded. When the human waste is put into the drying pot 10, the liquid level rises in proportion to the amount of the input, and the liquid level gradually approaches the contact detection rods 63 and 64. If the amount of one-time human waste input is equal to or less than the specified amount, the liquid level is the contact detection rod 6
No contact with 3, 64, contact detection rods 63, 64
There is no electrical conduction between the drying pot and the drying pot 10 through the human waste. However, when the amount of fruit urine more than the prescribed amount is added by one-time input of the raw sewage, the liquid level rises above the reference value (drying capacity), and the liquid level of the raw sewage comes into contact with the contact detection bars 63 and 64. To do. Most of this manure has a water content, so the drying pot 10
Since there is electrical continuity between the contact detection units 63 and 64 and the drying pot 10, even if there is some resistance, the state is in conduction. As described above, since the positive potential is applied to the contact detection rods 63 and 64 and the negative potential is applied to the drying pot 10, a minute current flows between them, and this minute current is a conduction detection circuit 80. , 81 and the energized state between the two is discriminated.

The conduction states by the contact detection rods 63 and 64 are respectively discriminated by the conduction detection circuits 80 and 81, and the fact that the liquid level is above a certain level is determined by the conduction detection circuits 80 and 81.
Determines. When it is determined by the conduction detecting circuits 80 and 81 that the amount of human waste more than the processing capacity is input, the result is output to the liquid surface position detecting circuit 82. In this liquid level position detection circuit 82, it is determined that a predetermined amount or more of human waste has been input (the liquid level has risen above a predetermined height) only when the two conduction detection circuits 80, 81 output. The output is output to the central processing control circuit 84. Then, the central processing control circuit 8
4, the shutter control circuit 90 and the expansion request control circuit 9
3, a signal is output to 3, the shutter 12 and the valve mechanism 13 are kept closed, and the introduction pipe 11 is not opened again. Therefore, even if the next user presses the processing switch 87, the shutter 12 and the valve mechanism 13 are not opened, and the human waste and other wastes are prevented from being thrown into the drying pot 10 any more. .

At the same time, the expansion request control circuit 93 causes the lamp 9
5 is lit to notify the outside that the human waste having a processing capacity or more has been put into the drying pot 10. The lighting of the lamp 95 informs that the human waste processing device 5 alone cannot process human waste, and that the temporary toilet 1 must be newly added as the number of users increases. That is, when the lamp 95 is constantly lit, the number of users of the temporary toilet 1 per hour is that the number of users of the temporary toilet 1 is larger than the processing capacity of the drying pot 10. Will give you more results than you expected. Therefore, another temporary toilet 1 having the same processing capacity can be newly added, and the number of temporary toilets 1 corresponding to the required processing capacity can be increased to suit the actual situation of the user.

In this way, the two contact detection rods 63,
While detecting that the height of the liquid surface is above a certain level by 64, the shutter 12 and the valve mechanism 13 are maintained in the closed state, and the drying pot 10 performs the above-described evaporative drying process. We are continuing.

<Determination of Contamination on Contact Detection Rods 63, 64>

As described above, the two contact detection rods 63, 6
4 constantly monitors the height of the liquid level in the drying pot 10 . This is a malfunction when only one of the contact detection rods 63 and 64 for detection is operated, and it is detected that the two contact detection rods 63 and 64 are at a liquid level higher than a predetermined height. Only at this time is the position of the liquid surface determined so as to accurately detect the height of the liquid surface. However, if the human waste treatment device 5 is used for a long time, the contact detection rod 63,
In some cases, 64 may be soiled or the insulation may not be maintained, and accurate detection may not be performed. In such a state, the liquid level cannot be measured accurately, which causes the liquid level position detection circuit 82 to malfunction. Therefore, the liquid level detecting means 5
When only one of the contact detection rods 63 and 64 of 0 and 51 remains conductive, the contact detection rods 63 and 6
The surface of No. 4 is contaminated and it is necessary to clean it.

That is, when the liquid level position detection circuit 82 continues to output a signal indicating that the liquid level is above a certain level only from one of the conduction detection circuits 80 and 81, a predetermined time After that, the contact detection rods 63, 64 self-determine that dirt is attached, and the judgment output is used as the dirt notification circuit 8
Output to 3. Therefore, the dirt notification circuit 83 turns on the lamp 85 to notify that one of the contact detection rods 63 and 64 is dirty, and to notify the maintenance worker to promptly perform the cleaning operation. . For this reason, the worker reads the lighting of the lamp 85 at the time of maintenance, removes the fixing fittings 59, 60 from the side surface of the drying pot 10, extracts the contact detection rods 63, 64 from the drying pot 10, and detects each contact detection stick 63, The outer periphery of 64 and the inlets 55 and 56 are cleaned. By this cleaning work, each contact detection rod 63, 64
Is capable of maintaining an insulating state, and the drying pot 10 is kept at a high resistance value.

<Stop of Evaporative Drying Operation>

As described above, by the heating by the heater 31 and the stirring action by the stirring blades 33 and the heat storage body 34,
Moisture, which is a major component of human waste stored in the drying pot 10, is sequentially evaporated. Heater 31
If the heating is continued by, the heater 31 will continue to be heated even after all the human waste in the drying pot 10 has evaporated. If this state continues, not only the heater 31 will be cut off, but also the drive mechanism 14 will continue to operate and the wear of the entire apparatus will start. Therefore, the drying is completed and the drying pot 1
When the human waste in 0 has completely evaporated, the operation of the drying process must be stopped immediately.

In order to deal with such a situation, in the human waste treating apparatus 5, the evaporation and drying process can be automatically stopped when the human waste in the drying pot 10 is completely evaporated. First, when all the human waste in the drying pot 10 is evaporated, the temperature of the side surface of the drying pot 10 rises. This temperature change is detected by the temperature sensor 52, and the change in temperature detected by the temperature sensor 52 is transmitted to the temperature discriminating circuit 86. When the temperature rises above a certain level, the drying process is completed. The central processing control circuit 84 transmits the signal to the central processing control circuit 84.

<Cleaning of the drying pot 10>

As described above, when the drying operation is completed due to the temperature change of the drying pot 10, the temperature sensor 52
Therefore, the temperature change is detected, and the drying process must be stopped. However, the drying pot 10 must be cleaned before shifting to the standby state. That is, raw sewage has been stored in the drying cauldron 10 is evaporated, and thereafter the dry remaining ones to the kettle 10 can not evaporate fibrous such components, they are remaining becomes residue. If such a residue remains in the drying kettle 10, the residue will accumulate in the drying kettle 10 for long-term use, which eventually causes the human waste to not be dried. For this reason, when one drying process is completed, the evaporation due to the heating is stopped, and then the drying pot 1
It is necessary to remove the residue and dust remaining in 0 and perform cleaning work.

As described above, when the temperature determination circuit 86 determines that the drying is completed, the central processing control circuit 84 outputs a signal to the motor control circuit 91 to drive the drive mechanism 14 and the motor 44 of the blower 23. Leave it running,
The motor 40 of the blower 22 is operated. A fan 41 is driven by the motor 40 to cause air to flow with a strong pressure through the blower pipe 24, the opening / closing valve 25, and the blower pipe 27, and the air is jetted toward the bottom of the drying pot 10 by the nozzle 42. Then, the dust and residue remaining in the drying pot 10 rises up as powdery powder. At this time, the drive mechanism 14 is continuously operating,
The heat storage body 34 is rotated at the bottom portion of the drying pot 10 so as to finely crush the residue that has not evaporated. Therefore, the residue blown up by the air ejected from the nozzle 42 is transmitted to the dust collector 16 through the exhaust pipe 20, and only the residue falls into the collection box 15 and is separated by the dust collector 16.
The clean air from which the residue has been separated passes through the reheating box 17 and the catalyst box 18 and is discharged to the outside in the same manner as described above.

This cleaning operation is performed each time the human waste is stored in the drying pot 10 and the evaporation and drying processes are performed, and the drying pot 10 is cleaned. Then, when the toilet bowl 6 is used for a long period of time, dust and residues accumulate in the collection box 15. For this reason, the maintenance box 1
By removing 5 and discarding the separated dust and residue, the human waste treatment device 5 can be used for a long period of time.

<Return to standby state>

As described above, if the residue in the drying pot 10 is removed by the air pressure from the blower 22, the toilet 6 should be returned to the standby state so that the toilet 6 can be used for the next user. I have to. Further, at night or the like, the temporary toilet 1 is not used for a long time, but at this time as well, it is in a standby state. The standby state is restored after a certain time has elapsed after the central processing control circuit 84 receives the signal from the temperature determination circuit 86, and the central processing is performed after the cleaning operation is completed. The control circuit 84 makes its own judgment.

When the central processing control circuit 84 determines that the standby state is set, the signals are transmitted to the motor control circuit 91, the valve control circuit 92, and the heater control circuit 94 to instruct to switch to the standby state. Then, the motor 40 stops its operation, stops blowing air from the blower 22, and drives the drive mechanism 1
4 stops its rotating operation. However, the motor 44 is still rotating. Further, the valve control circuit 92 closes the opening / closing valve 25 and opens the opening / closing valve 26. Further, the heater control circuit 94 terminates the energization of the heater 31, but still supplies the electric current to the heater 35 and the reheating heater 36.

This state is the same as the standby state described above, and only the motor 44, the heater 35, and the reheat heater 36 are operating in this standby state. The blower 22, the blower pipe 24, the open / close valve 26, and the blower pipe 28 which are stopped by switching the open / close valves 25 and 26.
The reheating box 17 and the catalyst box 18 have ejector 19
The air is drawn in by the negative pressure of. This is because the temperature of the catalyst 38 is not lowered and the catalyst 38 is made to stand by so that it can immediately respond to the next drying process. The standby state continues until the power switch 89 is opened.

<Stop of all devices>

This power switch 89 is opened (OFF
When the) is when the disposal apparatus 5 overall operation is stopped. That is, when the power switch 89 is opened, the central processing control circuit 84 determines to stop the entire operation of the human waste processing device 5, outputs a signal to the motor control circuit 91 and the heater control circuit 94, and rotates the motor 40. To stop the energization of the heater 35 and the reheating heater 36, and stop the operation of all the devices.

In this embodiment, in order to detect the height position of the liquid level of the human waste put in the drying pot 10, the human waste is used as a conductive material, and the contact detecting rods 63, 6 of the electric conductors are used.
I am using 4. However, in the present invention, for example, the contact detection rod 6 does not depend on the height position detection of the liquid surface by the direct contact.

A mechanism that determines a change in electrostatic potential between the liquid surface and the electrostatic detection plate and determines that the liquid surface has exceeded a predetermined level when there is a change in electrostatic potential above a certain level may be used. .
