Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a method for processing human waste outdoors where there is no purification facility, in transportation facilities such as ships and trains, and indoors where vacuum cars cannot enter due to closed spaces. The present invention relates to a drying device, and particularly to a human waste drying device capable of recovering water components from accumulated human waste to clean a toilet bowl.

[Conventional technology]

In ordinary houses, human waste excreted from the human body is discharged into the sewage system through flush toilets or the like, or temporarily stored in septic tanks and purified before being discharged into rivers. However, when events are held outdoors, such as sports days, trade fairs, and gatherings, where a large number of people gather, temporary toilets have been set up to dispose of human waste.

Traditionally, movable temporary toilets have been used to dispose of human waste outdoors or in places without purification facilities, but most of these toilets have a toilet tank to store the human waste, and the human waste excreted from the human body is stored in this toilet tank. It was something that could be stored inside. Therefore, after using the temporary toilet, the human waste stored in the toilet must be sucked out using a vacuum car, collected, and then disposed of, which is time-consuming.

In addition, transportation systems such as trains, buses, and ships that travel long distances are equipped with special tanks to store excreted human waste, and the human waste is stored in these tanks and treated with odor-proofing chemicals. Afterwards, it was common practice to collect the waste using a bagiyum car at the terminal station or transfer point.

In this way, in the conventional disposal of human waste in temporary latrines or mobile transportation, most of the waste is stored in the same state as excreted by the human body, and then collected and disposed of, which is extremely unhygienic. I had to say that it was. Therefore, if a temporary toilet is used for a long period of time, excreted human waste remains, which not only causes a bad odor, but also makes workers reluctant to dispose of it. It was not favorable either.

For these purposes, various hygienic treatment methods have been considered. For example, there is a method of adding chemicals together with human waste to sterilize and prevent odors. This is often used in transportation such as Shinkansen trains, but it has the disadvantage that it cannot be used for a long time because the chemicals circulate inside the tank, and the costs associated with the use of chemicals are high.

Another method has been considered to prevent the release of odors by storing human waste in bags made of plastic or the like and packing the bags. However, a plastic bag with a fairly large area must be used for one excretion, which increases processing costs, and the process of separating human waste from the plastic bag at a later date is cumbersome and requires a large-scale processing facility. It was hot.

Another method is being considered in which the excreted human waste is directly dried using the heat of a burner or the like. However, since the majority of human waste is water, it takes a lot of energy to remove this water, and the conventional method of simply incinerating and drying using firepower takes a long time to process. It was hot.

For this reason, the same inventor as the applicant of the present application has proposed a human waste processing device in which rotating blades are provided in a tank for storing human waste, and a heat storage body is housed in the tank. This device heats the tank from the outside and at the same time collects the blades to quickly dry the human waste and evaporate most of the moisture in the human waste (for example, Japanese Patent Application No.
C1, -293182) etc.).

However, this method simply heats and dries the stored human waste, and does not require water to be jetted into the toilet bowl and automatically cleaned after use, like in conventional flush toilets. It was impossible. For this reason, the next user has to use the toilet bowl while it is dirty, and it is not desirable for the user to use the toilet bowl with dirt still on it.

In addition, in places where temporary toilets are installed,
Usually, there are many places where there is no water supply or sewage system, and there is no way to supply water from the water supply and clean the toilet bowl with water like flush toilets.
In any case, this caused inconvenience to users.

[Problem to be solved by the invention]

Because of these drawbacks, even though mechanisms for drying human waste have improved, the function of the toilet bowl itself is similar to that of conventional pump-type toilet bowls, and the toilet bowl itself has been forced to be used in an unclean manner. Therefore, if the toilet bowl became dirty with filth, it had to be cleaned manually, and the traditional method of use remained the only option.

For these reasons, even in places where water and sewage connections are not available, there has been a desire for temporary toilets that can be kept clean at all times by flushing the toilet bowl with water in the same way as flush toilets in ordinary houses.

[Means for solving problems]

The present invention includes a heat-resistant container for storing human waste, a heating means for heating the container to dry the human waste, an agitation means having a plurality of blades for stirring the human waste stored in the container, and a heat-resistant container for storing human waste. It consists of a large number of stored heat storage bodies of different outer diameters, a tank that sucks up water components from the bottom of the container and stores them, and a cleaning means that squirts the water components stored in the tank into the toilet bowl. The present invention provides a human waste drying device characterized by the following.

[Effect]

In the present invention, human waste collected by a toilet bowl is once stored in a container. This container is filled with a large number of heat storage bodies of different types with different outer diameters, of which the heat storage bodies with smaller outer diameters sink to the bottom of the container, and the heat storage bodies with larger outer diameters float upwards. become. Therefore, the solid components of the human waste are retained in the upper part of the heat storage body, but the moisture such as urine passes through the gap in the heat storage body and flows into the lower part, and the water component and the solid matter are separated.

Water components such as urine are then sucked up from the bottom of the container and temporarily stored in the tank. By squirting the water component retained in this tank into the toilet bowl, it has the same effect as flushing water in a flush toilet, and the toilet bowl can be automatically cleaned every time the temporary toilet is used. This water component is part of excreted human waste such as urine, and is circulated through the toilet bowl, container, and tank, and can be used to constantly clean the toilet bowl.

Next, when a certain amount of human waste has been stored in the container, the container is heated to evaporate the water, which is the majority of the human waste, and diffuse it into the air.
Human waste can be disposed of hygienically.

73 is fixed, and these sensors 72, 73
The output of is connected to the controller 71.

Next, the operation of this embodiment will be explained.

<Preparation for use> First, in this temporary toilet 1, the base 2 is installed at a temporary location. Then, a certain amount or more of initial water A is injected into the water tank 9, and the water tank 9 is filled with water for preparation. Moreover, the three-way switching valve 43 is switched so that the connection sleeve 35 and the suction pipe 45 are connected.

<Using the temporary toilet 1> First, a person who wants to use the temporary toilet 1 enters the temporary toilet 1, faces the toilet bowl 6, and defecates. This excreted human waste falls from the toilet bowl 6 through the introduction pipe 31 and is stored inside the drying pot 14. This accumulated human waste is classified into substances such as feces, urine, and paper, but feces, paper, etc. are
0 and held at a higher position than the bottom of the drying pot 14. However, urine is a heat storage bulb 28,2
It will pass through the gap between 9 and 30 and accumulate at the bottom of the drying pot 14. Therefore, urine, which is a water component, and stool, which is a solid substance, are separated by the heat storage bulbs 28, 29, and 30 of different sizes.

Then, when the person who has finished using the toilet presses the start button 70, the signal is input to the controller 71 and the pump 68 is activated. Then water A in water tank 9
The water A is sucked up by the discharge pipe 67 and jetted toward the toilet bowl 6 from the jet pipe 69, so that the water A washes away the inner circumferential wall of the toilet bowl 6. The water that has washed away the dirt adhering to the inner wall of the toilet bowl 6 is returned to the drying pot 14 through the introduction pipe 31 in the same way as the human waste described above.

By pressing this start button 70, the user washes away the dirt in the toilet bowl 6 every time he uses the toilet, and always maintains a clean state. This operation can be repeated by pressing the start button 70. be exposed.
When the temporary toilet 1 is used a certain number of times and the remaining amount of water A in the water tank 9 becomes low, the sensor 72 detects the water level and transmits a signal to the controller 71. Therefore, the controller 71 operates the pump 65. Then, the water component such as urine accumulated at the bottom of the drying pot 14 is sucked up through the communication hole 25, and is passed through the air hole 24 to the drive pipe 2.
The water passes through the inside of the water tank 9 , passes through the vent 30 , the vent hole 36 , the three-way switching valve 43 , and the suction pipe 45 , and then is transferred into the water tank 9 from the suction pipe 66 . When the pump 65 performs the suction operation, the water accumulated at the bottom of the drying pot 14 is circulated and the water tank 9 is filled.
When the water A in the water tank 9 is supplied in excess of the required amount, the overflow water A overflows from the inflow pipe 27 and enters the drying pot 14.
returned inside. Note that the sensor 73 detects that the water A in the water tank 9 has reached a certain level or higher, and the controller 71 stops the operation of the pump 65. As a result, the water A in the water tank 9
The water A in the water tank 9 is always replenished automatically, and even if the number of users of the temporary toilet 1 increases, the water A in the water tank 9 is prevented from running out.

<Drying human waste> In this way, the temporary toilet 1 is used by the user, but if a certain amount or more of human waste is stored in the drying pot 14, the human waste is dried in the drying pot 14. Perform the drying process.

First, prior to the heating operation for processing, the controller 71 switches the three-way switching valve 43 to connect the connecting sleeve 35 and the communication pipe 44, and simultaneously operates the motors 56, 59 to
60 are driven respectively. Next, the burner 50 is operated to blow hot air from the burner pipe 16 into the space between the outer box 11 and the drying pot 14.

Since the fans 57 and 60 are already in operation, the air between the outer box 11 and the drying pot 14 is constantly sucked in the direction of the diffusion pipe 8 via the exhaust pipe 17, the catalyst box 57, and the exhaust pipe 54. . Furthermore, outside air flows into the heat exchange pipe 18 by the fan 60 and is caused to flow toward the connection sleeve 35 through the connection pipe 53. The air that has passed through the heat exchange pipe 18 is guided to the drive pipe 21, and is guided to the air hole 2.
4. It is ejected from the bottom of the drying pot 14 through the communication hole 25.

Next, since the fan 57 is operating, the outer box 1
The air pressure inside 1 is low, and the return pipe 61
The air inside the drying pot 14 flows through the exhaust pipe 61 and enters the outer box 11, and is then discharged to the outside through the diffusion pipe 8 together with the hot air from the burner 50.

In this order, the outer box 11 and the drying pot 1
The air inside 4 circulates and flows, respectively.

As mentioned above, the air heated by combustion in the burner 50 is released into the outer box 11 from the burner pipe 16, so this heat heats the entire lower part of the drying pot 14, and at the same time, the heat is transferred to the drying pot 14. The heat is also stored in the heat storage bodies 28, 29, and 30 housed inside. Therefore, the human waste stored in the drying pot 14 is heated by the heating of the entire drying pot 14 by the hot air from the burner 50 and by the heat storage elements 28, 29, and 30, and most of the components of the human waste are heated. Some water will begin to evaporate.

At the same time, the motor 42 is operated and the worm 3
8. Drive pipe 21 via worm gear 37
Rotate horizontally. For this reason, the drive pipe 21
The stirring blade 26 fixed to the drying pot 14 rotates horizontally close to the bottom of the drying pot 14, and the stirring blade 26 is fixed to the bottom of the drying pot 14 and rotates horizontally.
8, 29, and 30 are stirred, and the collected human waste is mixed while being stirred so that the temperature of the whole becomes uniform. During this stirring, human waste comes into contact with the surfaces of the heat storage bodies 28, 29, and 30;
The heat of the heat storage bodies 28, 29, and 30 is transmitted to the human waste through their surfaces, and the temperature of the whole human waste can be increased quickly.

Further, as described above, air from the outside is circulated within the heat exchange pipe 18 by the blower 58, and when air flows into the heat exchange pipe 18, heat from the burner pipe 16 is transferred to the inside of the heat exchange pipe 18. The air is heated and the heated air is connected to the connecting pipe 44.
It will be transmitted in the direction. This heated air passes through the inside of the drive pipe 21 through the ventilation holes 36 and 34, and after passing through the ventilation hole 24, the air passes through the communication hole 25.
It is spouted out towards the bottom of the drying pot 14.
Since this blown air has already been heated by the heat exchange pipe 18, it reaches a high temperature and comes into contact with the human waste, helping to dry the human waste and accelerating the rate of water evaporation.

In this way, the human waste in the drying pot 14 is heated by the heating from the outside of the drying pot 14 and the hot air blown from the inside, and begins to evaporate into water vapor. The water vapor evaporated in the evaporation pot 14 is sucked by the return pipe 61 and guided into the outer box 11. The steam evaporated from the drying pot 14 contains urea, ammonia, etc., which are some of the components of human waste, and produces an extremely foul odor. However, when the air flows into the outer box 11, since hot air from the burner 50 is injected into the outer box 11, it is reheated to an extremely high temperature and flows in the direction of the discharge pipe 17.

The air led to the discharge pipe 17 is first filtered by a filter 52 in the catalyst box 51 to remove solid components of human waste and dust, and only the air component is transmitted to the next catalyst 53. When the reheated malodorous air comes into contact with the catalyst body 53, the malodorous components are oxidized by the catalyst and removed. Then, the air from which the bad odor has been removed is sucked by the fan 51 via the connecting pipe 54, and is discharged to the outside air from the diffusion pipe 8.

Through the above-described series of operations, the human waste in the drying pot 14 is heated from the inside and outside of the drying pot 14 by being heated from outside the drying pot 14 and hot air heated by heat exchange is injected. Furthermore, since the total surface area of the heat accumulating bodies 28, 29, 30 is large, this heat is transferred to the human waste and its moisture can be evaporated extremely quickly. Through these series of operations, most of the moisture in the human waste in the drying pot 14 is evaporated, and fine solid components are collected by the filter 52. This drying process can be repeated many times, so
There is no need to collect the accumulated human waste using a vacuum car or the like, and the temporary toilet 1 can be operated for a long period of time.

<Return> The burner 50 operates for a predetermined time and the drying pot 1
Once the human waste in 4 has been dried and evaporated, the operation of burner 50 is stopped, and at the same time, the operation of motor 5 is stopped.
The operations of toilets 6, 59, and 42 will be stopped, and the temporary toilet 1 will be on standby for use for urination.
When the operation of the drive pipe 21 is stopped during this switching to standby, the heat storage bodies 28, 29, and 30 housed in the drying pot 14 are separated into upper and lower parts depending on the size of their external shapes, and the heat storage bulbs 28 with small outer diameters is collected at the lower part of the drying pot 14, and the heat storage body 30 having a large outer diameter is collected upward. and controller 71
Then, the three-way switching valve 43 is switched to reverse its connection, and preparations are made for flushing the toilet bowl 6 in the same manner as described above.

FIG. 6 is a flowchart showing the operation in this embodiment.

Moreover, FIG. 7 is an explanatory diagram showing a connection situation with a conduit in another embodiment of the present invention. This embodiment describes a configuration in which human waste is heated and dried using an electric heater without using thermal power such as a burner. Note that the same members as in FIG. 5 are given the same reference numerals, and their explanations are omitted.

A flat heater 81 for heating is wound around the outer periphery of the drying pot 14, and the drying pot 14 is heated from the outer periphery by this heater 81. A plurality of heat exchange pipes 82 are wound around the lower half of the outer circumference of the drying pot 14, and the heat exchange pipes 82 are wound around the outer circumference of the heater 81. Furthermore, this drying pot 1
A plurality of reheating pipes 83 are wound around the outer periphery of the upper half of 4 so as to contact the outer periphery of the heater 81.

A blower 84 is connected to one end of this heat exchange pipe 80, and a motor 8 in the blower 84 is connected to one end of the heat exchange pipe 80.
5 has a fan 86 fixed to it, and this fan 8
6 allows air from outside to be forced into the heat exchange pipe 82. The other end of the heat exchange pipe 82 is connected to the communication pipe 44. Further, a suction pipe 87 communicating with the inside of the drying pot 14 is connected to one end of a reheating heater 83, and the other end of the reheating heater 83 is connected to the catalyst box 51. The space between the inner wall of the outer box 11 and the outer wall of the drying pot 14 is filled with a heat insulating material 88 such as glass wool to isolate the drying pot 14 from heat from the outside.

In this embodiment, when using the toilet bowl 6 to defecate, the pump 68 is operated in the same way as described above to suck up the water A in the water tank 9, and the water A is pumped into the toilet bowl from the spout pipe 69. Make it squirt to remove dirt.

When an appropriate amount of human waste is accumulated in the drying pot 14, the operation of drying the human waste is started. First, the controller 71 switches the switching valve 43 to connect the connecting pipe 44 and the connecting sleeve 35, and at the same time energizes the heater 81 to generate heat to heat the drying pot 14 from its outer periphery, thereby heating the entire drying pot 14. heat up.

Next, the controller 71 controls the motors 42, 85, 5
Operate 6. Through this operation, external air is blown from the blower 84 into the heat exchange pipe 82, and the air that has passed through the heat exchange pipe 82 is transferred to the communication pipe 4.
4. Flows into the drive pipe 21 via the switching valve 43. This air is blown out from the communication hole 25 at the bottom of the drive pipe 21. Also, Juan 5
7 is being driven, the air in the reheating pipe 83 is sucked, and the air in the drying pot 14 is diverted by the suction pipe 87 through the path of the suction pipe, the reheating heater 83, and the catalyst box 51. It flows and is released into the atmosphere from the diffusion pipe 8.

Since the heat exchange pipe 82 is in contact with the outer periphery of the energized heater 81, air from the outside sent by the fan 86 is transferred to the heat exchange pipe 82.
It is heated as it passes through the interior. This heated air is blown out from the bottom of the drying pot 14, and the human waste inside the drying pot 14 is heated from both the outer periphery and the inside. Further, since the motor 42 is operated, the drive pipe 21 is rotated,
The stirring blade 26 stirs the heat storage bodies 28, 29, and 30, and the temperature of the human waste is uniformly raised and its moisture is evaporated.

The evaporated moisture is sucked by the suction pipe 87, and as it passes through the reheating pipe 83, it is heated again by the heater 81 and raised to a high temperature, and then flows into the catalyst box 81. Catalyst box 5
1, the filter 52 removes dust from the air.
After dust and the like are removed, the high-temperature air contacts the catalyst 53 to oxidize impurities such as odors, making the air odorless. Further, the air that has passed through the catalyst 53 is discharged to the outside by a fan 57, and water vapor, which is a major component of human waste, is diffused into the atmosphere and treated.

In this embodiment, as described above, the replenishment of water in the water tank 9 and the incineration of human waste are performed automatically, and the heat source for heating is performed by the heater 81, so that the power is not required. It can be used anywhere as long as there is a power supply available, and it is highly safe because it does not involve fire.

〔Effect of the invention〕
