Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is capable of treating human waste in an outdoor space without a purification treatment device, in transportation facilities such as ships and trains, and in tunnels where vacuum cars cannot enter. The present invention relates to a human waste drying device.

[Conventional technology]

The human excrement excreted from the human body is released into the sewage in a normal house by a flush toilet or the like, or is temporarily stored in a septic tank to be purified and then released into a general river. However, temporary venues are provided at the venues where a large number of personnel such as athletic events, trade fairs, and meetings are held outdoors to temporarily treat human waste.

In the conventional treatment of human waste in the outdoors or in a place without a purification facility, a temporary toilet that can be moved was used, but most of them have a toilet that stores human waste, and the human waste excreted from the human body is the toilet. It was stored in. Therefore, it is necessary to dispose of the human waste stored in the temporary toilet after the end of the entertainment. For this reason, the human waste collected by a vacuum car or the like must be sucked, collected in a tank, and then purified or discharged to be processed, which is troublesome.

In addition, in trains, buses, ships, and other transportation systems that travel long distances, a dedicated tank for storing excreted excrement is provided, and the excrement is stored in this tank and deodorized with chemicals. After processing, it was a common method to collect it with a vacuum car at the terminal station or relay point.

As described above, in the conventional temporary treatment or in the treatment of human waste in a movable transportation facility, most of the waste is stored in the original form excreted from the human body and then collected, which is extremely unsanitary. I had to say that. For this reason, the excreted excrement remains in the tank when used for a long period of time, which not only causes a bad odor, but also is unfavorable for the modernization of the treatment because the worker dislikes it.

For this purpose, various methods of treating sanitarily have been considered in the past. For example, there is a method of sterilizing and deodorizing by adding chemicals together with human waste. Although this is often used for transportation such as Shinkansen, it has the drawback that it cannot be used for a long time because the chemical circulates in the tank, and the cost of using the chemical is high.

In addition, a method has also been considered in which human waste is stored in a bag made of vinyl or the like and the plastic bag is packed to prevent odor from being emitted. However, a vinyl bag having a considerably large area has to be used for one excretion, and the treatment cost is high and the post-treatment for separating human waste from the vinyl bag at a later date is troublesome.

In addition, a method of directly drying excreted excrement with a heating power such as a burner is also considered. However, since most of human waste has water as a component, a large amount of energy is required to remove this water and a single treatment time becomes long.

From this point of view, the same inventor as the applicant of the present application is
We have proposed a human waste treatment device in which a rotating blade is provided in a tank that stores human waste, and a heat storage body is stored in the tank.
With this configuration, by heating the tank from the outside and rotating the blades at the same time, the human waste can be quickly dried and most of the water in the human waste can be evaporated (for example, Japanese Patent Application No. 124150/1988). Issue, Japanese Patent Application No. 172852, 63, Japanese Patent Application
No. 190857, 62).

However, in these drying methods, when the blades rotate in the tank, the blades rotate close to the bottom of the tank, so that the human waste adhering to the periphery of the tank cannot be crushed. Also, since the blades try to move the heat storage body directly, if the heat storage body gets caught at the bottom of the tank, the heat storage body will be forced to rotate, which makes the operation awkward and burdens the motor etc. there were.

[Problems to be Solved by the Invention]

In view of the above-mentioned drawbacks, the present invention is intended to store human waste excreted from a human body in a tank and heat the tank from the outside to rapidly dry the human waste stored therein by heating a heat storage body. The agitating blade approaches the bottom of the tank and also approaches the inner peripheral wall, and its shape moves over a large area. Therefore, it is possible to scrape off the human waste adhering to the inner peripheral wall of the tank, and at the same time, to allow the heat storage body to pass through the opening in the center of the U-shape so that no excessive force is applied to the heat storage body. The present invention provides a human waste drying device.

[Action]

In the present invention, the human waste is stored in a heat-resistant container, and the human waste is dried by heating the container from the outside.
Since a heat-resistant heat storage material such as ceramic is stored in the container and the heat storage material and human waste can be stirred by the blade of the stirring means, the heat from the outside of the container is the heat of the container itself and its heat storage. The whole body is warmed up, and the heat released from the surface of the heat storage body heats the excrement to rapidly evaporate the water.

And, since the blade formed in a slightly U-shape is fixed to this stirring means, the lower surface of this blade rotates close to the bottom of the tank to scrape off the human waste adhered to the bottom of the tank and at the same time the heat storage bulb. Can be moved. Since the side surface of the blade moves closer to the inner peripheral wall of the tank, it is possible to scrape off the human waste that has dried and adhered to the inner peripheral wall of the tank. For this reason, the inside of the tank is always kept clean, the dried human waste is crushed, and can be sent to the next treatment by a transfer method such as wind. Furthermore, the heat storage body rotated in the tank can pass through the window hole opened in the center of this blade, so if the heat storage body gets caught at the bottom of the tank, it will pass through the window hole of this blade. Since the blades can be moved, an unnecessary force is not applied to the blades, and the stirring means can be operated smoothly.

Next, the operation of this embodiment will be described.

A person who intends to use the urinal first enters the temporary toilet 1 and excretes it toward the toilet 6. The excreted excrement falls from the toilet bowl 6 through the introduction pipe 31 and is temporarily stored in the drying pot 16. At this time, the shutter 48 first opens, and after the manure has been placed on the shutter 49, the shutter 48 closes. After that, the shutter 49 is opened, and the excrement and urine fall into the drying pot 16 and are stored therein. This operation is performed automatically, and the excrement does not remain in the toilet bowl 6 to make the next user uncomfortable, and the odor of excrement from the drying pot 16 is prevented from rising into the temporary toilet 1. There is. When the temporary toilet 1 is used a certain number of times and a certain amount of human waste is stored in the drying pot 16, drying is started by a command from a timer or a sensor.

In this drying process, first, the heater 18 is energized to heat the heater 18 and operate the motor 34 to rotate the rotary shaft 21 at a constant speed via the sprocket wheel 36, the chain 37, and the spcket wheel 33. Let In this rotation operation, as described above, the rotary shaft 21
The rotating direction of the push rod 28 and the rotating side piece 29 is operated so that the inclined surface thereof is rotated forward, and the push rod 28 and the rotating side piece 29 are rotated in the direction indicated by A in FIG.

At the same time, the motors 46 and 64 are driven, and the fans 47 and 65, respectively.
To rotate. By this operation, air from the outside is introduced between the middle plate 13 and the bottom plate 19 via the conduction tube 40, and the press-fitted air passes through the ventilation hole 23 and the communication hole 41 and is above the middle plate 13. Inflow. Then, the inflowing air flows around the reflection plate 42 and around the through hole 43 so as to come into contact with the heater 18.
The air heated by coming into contact with the heater 18 further rises, and the gap B formed between the rotary shaft 21 and the moving-in cylinder 17 is increased.
And is discharged at the upper end of the moving-in cylinder 17, and then the introducing cylinder 17
Therefore, the clearance C formed between the outside and the inner wall of the rotary cylinder 25 moves downward. Eventually, the air turns
The heated air is discharged to the inside of the drying pot 16 through the opening at the lower part of the above.

Further, since the heater 18 heats the drying pot 16 from its bottom surface and the radiant heat is concentrated by the reflector 42 toward the bottom face of the drying pot 16, the human waste stored in the drying pot 16 is warmed. At the same time, the heat is also transferred to the heat storage body 30 in the drying pot 16, and the heat storage body 30 retains the heat. Therefore, the human waste inside the drying pot 16 is heated by the heater 18 from the lower part, the heat storage body.
The heat generated from 30 and the warmed air discharged from the lower opening of the rotary cylinder 25 are respectively heated, and water evaporation and drying of human waste are started.

At this time, since the rotary cylinder 25 is rotated, the connecting piece 27
The rotating cylinder 25 combined by means of the rotation rotates the push rod 28 and the rotating side piece 29 slowly in the space inside the drying pot 16, and the pushing rod 28 pushes the heat storage body 30 while drying the pot. Rotate in sequence on the bottom surface of the bottom of 16. For this reason,
Since the heat storage body 30 moves on the inner bottom surface of the drying cauldron 16, the accumulated human waste always comes into close contact with the drying cauldron 16, so that the speed of drying the human waste is increased. At the same time, since the heat storage body 30 stirs the raw sewage, the raw sewage is cut into fine pieces, and the shape when it becomes ash is finely crushed, so that it can be easily lifted up by air.

Further, since the rotating side piece 29 rotates while approaching the inner wall of the drying pot 16, the straight tip of the side surface scrapes off the residue of human waste adhered to the inner wall of the drying pot 16 during the drying process. It is dropped and is constantly cleaned so that the dregs of human waste do not stick to the inner wall of the drying pot 16. Therefore, the human waste does not solidify on the inner wall of the drying pot 16, and the heat transfer from the drying pot 16 to the human waste becomes extremely efficient.

When the heat storage body 30 is moved by the push rod 28,
28 is performed by pushing the heat storage body 30, but the heat storage body 30 may come into contact with a slag stuck to the bottom surface of the drying pot 16 to cause resistance to movement. In this case, if the push rod 28 forcibly pushes the heat storage body 30, the load of the motor 34 and an unnecessary burden will be imposed. body
30 are collected on the outer surface of the rotary cylinder 25 and near the base of the push rod 28.

Therefore, the inner heat storage body 30 that is closest to the push rod 28 is
Is pushed up by the acting force of the other heat storage body 30, and the acting force D works so as to be lifted to the upper surface of the push rod 28. As a result, the leading heat storage body 30 is pushed as shown by 30D in FIG. It rides on the upper surface of the moving rod 28, then falls on the upper surface of the pushing rod 28, moves in the direction E in FIG. 6, and is dropped on the rear portion of the pushing rod 28 as indicated by 30E. As a result, the heat storage body 30
Moves in the directions of D and E, and creates a relief so that the heat storage body 30 is not forced by the push rod 28. Further, at the same time, when the heat storage body 30 falls from the push rod 28, it comes into contact with the bottom surface of the drying pot 16 with a light impact, so that the dreg of human waste deposited on the surface of the heat storage body 30 falls due to the impact. Therefore, it will be useful for cleaning the heat storage body 30.

In this manner, the heat of the heater 18 and the rotation of the rotary shaft 21 cause the water content of the raw sewage inside the drying pot 16 to evaporate, and most of the components of the raw sewage are released as steam. This water vapor flows from the discharge pipe 32 and is transmitted to the dust collector 52 via the communication pipe 51.

In the cyclone dust collector 53 in the dust collector 52, the inflowing air swirls at the inner wall of the cyclone dust collector 53 at a high speed, the mass of slag falls downward, and the sewage dregs and ash that does not evaporate fall into the slag plate
Collected on 55. The components of steam remain in the slag and ash accumulated in the slag tray 55, and when the temperature falls in the cyclone dust collector 53, water droplets are deposited on the slag tray 55. Therefore, the slag dish 55 is heated by the heater 56 to re-evaporate the moisture and transferred to the reheating chamber 57. The reheating chamber 57 has a reheating heater 58, and the inflowing air is reheated by the reheating heater 58. Then, the warmed air is sent to the catalyst chamber 59, and by contacting the surface of the catalyst 60 inside, the components such as ammonia that cause a bad odor are oxidized and the odor is removed.

Further, when the fan 65 is operating, the outside air is always transferred from the suction cylinder 61 to the diffusion pipe 8. The flowing air has a high speed when passing through the ejector 62 and lowers the pressure around the suction cylinder 61, so that the air from the catalyst chamber 59 is sucked and sucked into the suction cylinder 61 side. Therefore, the air inside the dust collector 52, the reheating chamber 57, and the catalyst chamber 59 is sequentially discharged, mixed with the air from the blower 63, and discharged from the upper end of the diffusion pipe 8 to the atmosphere.

By repeating the above cycle, most of the human waste inside the drying pot 16 is evaporated, and the drying cycle is continued until the drying pot 16 becomes empty. Then, when all the human waste inside is dried and there is no human waste stored in the drying pot 16, the operation of the heater 18, the motors 44, 64, the heater 56, and the reheat heater 58 is stopped, and the next It will be waiting for the drying process.

Next, FIG. 7 shows another embodiment of the present invention.

In this embodiment, the same members as those in FIGS. 1 and 3 are designated by the same reference numerals and the description thereof is omitted.

On the left and right sides of the rotary cylinder 25, U-shaped vane plates 70 and 71 formed of a thin metal plate are fixed at opposite positions. The blades 70, 71 are formed so that their lower sides are close to the bottom surface of the drying pot 16, and the side edges of the blades 70, 71 are formed so as to be close to the inner peripheral wall of the drying pot 16. There is. Further, U-shaped notches 72, 73 are formed in the center of each blade 70, 71, and between the blades 70, 71 and the side surface of the rotary cylinder 25 by the notches 72, 73. A rectangular window hole is formed.

In this embodiment, the lower sides of the blades 70, 71 are pushed around while rotating the heat storage body 30 and can be sequentially moved on the bottom surface of the drying pot 16, so in the rotational movement of the heat storage body 30,
The solid component of human waste can be crushed.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, when the stirring mechanism rotates inside the drying pot, the blades are rotated closer to the bottom surface and the inner peripheral wall of the drying pot to remove the attached residue. Can be scraped off. Therefore, the inner wall of the drying pot can be constantly cleaned, the thermal conductivity can be increased, and unnecessary residues can be removed for automatic cleaning.
