Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a deodorizing apparatus that changes a malodorous component from odorous air into an odorless state by oxidizing / reducing it, and in particular, a great effect can be obtained by combining it with a mechanism for treating manure. Deodorizing device.
[0002]
[Prior art]
The excreta excreted from the human body is usually discharged into a sewer pipe by a flush toilet or the like in a general house, or temporarily stored in a septic tank and purified before being discharged into a river. However, when performing outdoors, for example, in venues where a large number of personnel, such as athletic meet, trade fair, and gathering, are provided, a temporary toilet has been provided to eliminate the physiological phenomenon of participants.
[0003]
As described above, a temporary toilet that can be moved is used in the treatment of urine in the outdoors or in a place without a purification facility. However, most of them have a structure with a toilet bowl for temporarily storing the urine, and the urine excreted from the human body is stored in this toilet as it is. Therefore, after using the temporary toilet, the manure stored in the toilet tank must be collected by a vacuum car or the like and transferred to a manure treatment facility. For this reason, the process after collection | recovery was needed, the post process took time, and it was unsanitary.
[0004]
In addition, transportation systems such as trains, buses, and ships that travel long distances have a dedicated tank for storing excreted excreta, and the excreta is stored in this tank and deodorized with chemicals. After that, a method of collecting by a vacuum car at a terminal station or a relay point was common.
[0005]
As described above, most of the treatment of urine in a conventional temporary toilet or movable transportation system is stored in a state in which it is excreted from the human body and then collected. For this reason, it must be said that any of the storage method, the recovery method, and the treatment method is non-modern and extremely unsanitary. Therefore, if a temporary toilet is used for a long time, excreted excreta remains in the tank, causing a bad odor. Further, since the work of cleaning the temporary toilet after use is disliked by workers, it is not preferable for the modernization of the maintenance of the temporary toilet and the toilet of the transportation facility.
[0006]
From such a situation, various methods for treating urine hygienically have been conventionally considered. For example, there is a method of sterilizing and deodorizing by adding chemicals together with manure. This method is often used for transportation such as the Shinkansen. However, since urine containing chemicals circulates between the tank and the toilet bowl, the water flowing through the toilet bowl becomes dirty and odors are generated when used for a long time. It was unpopular for users. In addition, in order to empty the tank and prepare it for the next use, a large amount of chemicals must be put into the tank, which has the disadvantage of increasing costs due to chemicals.
[0007]
Furthermore, a method of preventing the odor from spreading by storing the manure in a bag of vinyl or the like and packing it is also considered. However, it is necessary to use a plastic bag having a considerably large area in one excretion, which increases the processing cost and requires processing for separating urine from the plastic bag at a later date. In this method, the processing until packing is relatively easy, but the subsequent processing is troublesome and the processing facility becomes large.
[0008]
Furthermore, a method is also considered in which excreted excreta is stored in a sealed evaporation container, and the excreta is directly heated and evaporated by a burner. For example, the patent publication No. 17236, the patent publication No. 2545, the patent publication No. 3149, the patent publication No. 58239, the patent publication No. 110268, the patent publication No. 165415 It has been known. However, with these methods, the flame of the burner is ejected into the urine and evaporated from the surface, so the water, which is the major component of urine, cannot be efficiently evaporated, and the urine is completely processed. It took a lot of energy to do.
[0009]
Further, in these configurations, the evaporation container is not cleaned after the urine is dried, and in the long-term use, the residue that could not be evaporated from the urine is deposited on the bottom of the evaporation container, resulting in poor thermal efficiency. It was. In such a case, in order to clean the residue, the apparatus must be disassembled and maintained each time, and there is a disadvantage that it takes time and money for maintenance.
[0010]
Thus, many problems remain in the treatment of manure in the temporary toilet, and the excreted excreta cannot be completely treated inside the temporary toilet. Due to such social demand, the same applicant as the applicant of the present application has proposed a manure treatment apparatus that can evaporate water, which is a major component of manure, by heating the manure. This proposed excrement disposal apparatus is used in a temporary toilet, and a sealed drying pot (heat-resistant evaporation container) for storing excreta is provided in the apparatus, and in this drying pot A rotatable stirring blade is pivotally supported, and a plurality of heat accumulators that roll on the inner bottom together with manure according to the rotation of the stirring blade are accommodated in the drying pot.
[0011]
Then, this drying kettle is heated from the outside to heat the manure in the drying kettle, and at the same time, the stirring blades are rotated to mix the manure and quickly evaporate the water in the manure. At the time of this evaporation, the spherical heat accumulator rolls at the bottom of the drying kettle, heating the temperature of the urine uniformly, and also transferring its own heat to the urine to increase the heating rate. (For example, there is Japanese Patent Application No. 124150150).
[0012]
This mechanism is basic, and the applicant has successively proposed improved manure treatment devices. Japanese Patent Application No. 164594 shows a configuration in which a pipe for pumping air and an exhaust pipe are connected to a drying kettle, and a dust collector and a condenser are connected to the exhaust pipe. With this mechanism, water vapor condenses and collects in the urine evaporated inside the drying kettle and can be used by circulating it in the washing water. Dust remaining in the drying kettle after drying the urine is sucked together with air. Thus, the dust can be separated from the air by a dust collector. With this mechanism, moisture can be recovered from the urine put into the drying pot, dust that cannot be evaporated remaining in the drying pot after drying the urine can be cleaned, and the urine processing device can be used continuously. It is.
[0013]
In Japanese Patent Application No. 411577, the urine processing device is unitized so that it can be easily attached to a temporary toilet. In this mechanism, the structure of the drying pot is formed in a cylindrical shape so that manure can be poured from the side of the drying pot. For this reason, there is no need to dispose a toilet bowl on the top of the drying pot, and the height of the apparatus can be reduced.
[0014]
Japanese Patent Application No. 41,559 has a configuration in which a storage tank for storing urine collected by a urinal is provided, and the storage tank and the toilet are connected by an injection jet pipe. In this configuration, the urine is excreted in the toilet and the urine is collected by the urinal. When the urine is put into the drying pot, the urine is ejected from the storage tank to the toilet, Can be put into a drying kettle. For this reason, the toilet bowl can be cleaned with urine, and the temporary toilet can be washed with water even in a place where the water supply cannot be installed.
[0015]
Furthermore, Japanese Patent Application No. 067538 shows a mechanism in which a liquid level sensor is inserted from the side of the drying kettle, and the position of the liquid level of manure injected into the drying kettle can always be detected. . In this mechanism, by detecting and judging the liquid level of urine, it is possible to prevent a large amount of urine from being thrown in temporarily so that the ability to evaporate urine is not reduced. Occurrence can be prevented.
[0016]
In Japanese Patent Application No. 189280, a reheating box having a heater built in between the blower and the catalyst box is disposed, and a bypass is provided between the catalyst box and the pipe connecting the drying kettle and the dust collector. is there. In this configuration, during the evaporating process of manure, air from the drying kettle can be made to flow to the catalyst box by bypass to increase the efficiency of air flow. Further, when the drying pot is cleaned, the bypass is closed, and the air containing the dust can flow as it is to the dust collector.
[0017]
In addition, Japanese Patent Application No. 189281 is an improvement of Japanese Patent Application No. 189280. A bypass pipe is connected to the pipe connecting the drying kettle and the dust collector, and the end of the bypass pipe is connected to an ejector. The negative pressure side is connected, and the catalyst box is connected to the ejector. In this configuration, when the bypass pipe is open, the air in the drying kettle is forcibly sucked by the ejector and flows into the catalyst box, so that the flow efficiency of the air in the drying kettle is increased and evaporation is promoted. effective.
[0018]
In Japanese Patent Application No. 265237, a garbage collection box is connected to an exhaust pipe of a drying kettle, and a garbage bag formed of paper, cloth or the like is stored in the garbage collection box. In this configuration, when the drying kettle is cleaned, air containing dust is allowed to flow into the garbage bag, and only dust can pass through the dust bag to separate the dust. Compared with a cyclone type dust collector, there is an effect that dust can be reliably separated.
[0019]
In Japanese Patent Application No. 031170, the toilet bowl and the urine processing device are separated, and after the urine put in the toilet bowl is stored in a tank, it can be continuously evaporated and dried in a badge manner. is there. In this manure processing apparatus, an opening for pouring urine is formed at the top of a slightly spherical drying kettle that can be rotated on a horizontal axis, and a spherical heat storage body is housed inside the drying kettle, and the bottom of the drying kettle It is the structure which provided the burner which can heat. With this configuration, the manure charged in the drying kettle is evaporated and dried by the heat of the burner, and during this process, the manure can be stirred by the heat storage body by swinging the drying kettle, and after drying, the drying kettle is rotated. Thus, dust can be dropped from the opening.
[0020]
In Japanese Patent Application No. 121968, a switching valve is interposed between the blower pipe and the exhaust pipe of the drying pot, and the garbage collection box and the blower can be connected in series to the drying pot via the switching valve. In this configuration, air is circulated inside the urine processing apparatus when the drying kettle is cleaned, and the dust collection efficiency is improved.
[0021]
In Japanese Patent Application No. 125360, a high frequency coil is installed on the lower surface of the drying kettle, and electromagnetic waves are generated by supplying high frequency power to the high frequency coil. Since high-frequency electromagnetic waves are agitated in the drying kettle, the drying kettle itself can generate heat and heat manure instead of direct heating. For this reason, only the drying kettle required quickly can be heated, and the heat loss is reduced.
[0022]
In Japanese Patent Application No. 307135, the drying kettle itself is normally upright, and the upper part of the drying kettle is always open, so that it can be turned over only during cleaning. A heat storage body is housed inside the drying pot, and a cover plate that can be closed at the time of falling is provided. In this configuration, during the process of evaporating and drying the urine charged in the drying kettle, the drying kettle itself is stationary and standing upright, but during the cleaning process after the urine has evaporated, the drying kettle is It can fall down and the dust remaining inside can be discharged from the opening. When this dust is released, the cover plate (having a plurality of small holes on its surface) automatically closes the opening of the drying pot, preventing the heat storage body from falling, Can be discharged from a small hole in the lid plate to the trash tray, and the configuration of the manure treatment apparatus can be simplified.
[0023]
Furthermore, in Japanese Patent Application No. 314445, a drying kettle is supported rotatably, the motor output is meshed with the outer circumference of the drying kettle, and a plurality of spherical heat accumulators are placed in the drying kettle. It has a structure in which three baffle plates are inserted from the cover plate that is housed and located at the top of the drying kettle toward the inside of the drying kettle. In this configuration, unlike the drying pot of the conventional manure processing apparatus, the drying pot itself rotates around a vertical axis, and the manure can be heated by electromagnetic waves from the high frequency coil. And the heat storage body accommodated in the inside of the drying kettle does not rotate with the drying kettle by the baffle plate but rolls at the bottom of the drying kettle and can stir and heat the manure. In this configuration, it is not necessary to rotate the stirring blade inside the drying kettle, so that the height of the entire manure processing apparatus can be reduced. In addition, in the configuration in which the rotating blades are rotated, an excellent effect of eliminating a failure caused by entanglement of the rotating blades with foreign matters (for example, ballpoint pens, clothes, watches, etc.) other than manure put in the drying pot. It is what has.
[0024]
Similarly, in Japanese Patent Application No. 151631, a drying kettle is supported rotatably, the motor output is meshed with the outer circumference of the drying kettle, and a spherical heat accumulator is placed in the drying kettle. And a baffle plate is inserted from the lid plate located at the top of the drying kettle toward the inside of the drying kettle. Even in this configuration, the drying kettle itself rotates about a vertical axis, and the manure can be heated by electromagnetic waves from the high frequency coil. In this invention, the baffle plate is formed by one piece fixed to the suction pipe, and the heat storage body is not fitted between the plurality of baffle plates, so that the heat storage body can be reliably rolled by the rotation of the drying pot. Met.
[0025]
In these newly proposed manure processing apparatuses, excreted manure can be heated while sealed in the drying kettle, and the manure can be mixed by rotating the stirring blade and the drying kettle. In the heated manure, the whole temperature rises uniformly, the water which is the most component evaporates, and it is emitted into the atmosphere as water vapor. By this heating and mixing, the evaporation rate of manure increases, and the treatment time of manure can be shortened. In addition, the water vapor diffused in the atmosphere is made non-brominated with a catalyst, etc., and it does not emit bad odors even in places where people are standing or where many people are gathering. This is also preferable from the viewpoint of the above.
[0026]
It is very hygienic to evaporate and diffuse manure in the sealed evaporation container in this way, and the work can be systemized, so that it does not place a burden on the worker in maintenance or the like. However, most conventional manure processing devices have a configuration in which a drying kettle is fixed and the stirring blades are rotated inside the drying kettle to mix manure. In this mechanism, when a foreign substance other than manure that cannot evaporate is put into the drying pot, the rotating stirring blade is engaged with the foreign substance, which often causes a failure. For example, metal ballpoint pens, belts, clothes, etc. may be thrown into the toilet bowl due to carelessness of the user. When these foreign matters are put into the drying kettle, the foreign matter bites between the stirring blades and the drying kettle, causing a phenomenon that the rotation of the stirring vanes is stopped or the stirring vanes and the drying kettle are worn.
[0027]
In addition, if the stirring blades are stored inside the drying kettle, the internal space of the limited drying kettle is narrowed by these mechanisms, and thus the internal space of the drying kettle cannot be used effectively. It was.
[0028]
In order to eliminate these disadvantages, the Japanese Patent Application No. 314445 and the Japanese Patent Application No. 151631 have a configuration in which the drying kettle itself is rotated so that manure can be mixed without using a stirring blade. It is. However, in this mechanism, the drying kettle must be rotatably supported, and the drying kettle must be supported so that it does not move in the vertical direction and the central axis is not displaced. This is because if the rotating drying kettle moves up and down or the rotating shaft causes a miso movement, the opening end of the drying kettle will be separated from the cover plate, and the airtightness of the drying kettle will not be maintained.
[0029]
Thus, if it is going to restrict | limit the rotational motion of a drying pot, the control mechanism (a roller etc.) of two directions of an up-down direction and a rotation direction will be needed, and this control mechanism must be complicated. In addition, if the regulation mechanism becomes complicated, it takes time to assemble the drying kettle, and it takes time to remove the drying kettle for inspection and maintenance of the urine processing device. .
[0030]
Dust remaining after evaporating and drying manure in this drying kettle must be removed for continuous treatment of manure, but a suction pipe for cleaning is attached to the drying kettle for a specified length. It was difficult to control the insertion. In the past, the amount of movement of the suction pipe was detected and controlled to move up and down by an appropriate length, but the mechanism for moving the suction pipe and the control mechanism were complicated.
[0031]
For this reason, the applicant of the present application has applied for a manure treatment apparatus in which these defects are improved by Japanese Patent Application No. 219457. In this newly proposed manure processing apparatus, a rotation holding means is provided at the upper part of the gantry, an evaporation container is suspended at the lower part of the rotation holding means, and an electromagnetic heating means is provided at an interval on the lower surface of the evaporation container. It is characterized by. In this proposed configuration, since the evaporation container is suspended and rotated, there is no need to provide any support means on the lower and side surfaces, and the mechanism for holding the evaporation container is extremely simple. Also, with this configuration, it is possible to remove only the evaporation container from the lower part of the rotation holding means, and it is easy to expose the inside of the evaporation container to the outside for periodic inspection and maintenance.
[0032]
[Problems to be solved by the invention]
As described above, treatment apparatuses for evaporating and drying manure have been developed with various mechanisms. In this case, when the urine is evaporated, the water vapor evaporated from the urine contains malodorous components such as ammonia and urea, and the odor is diffused to the surroundings as it is. For this reason, in any conventional manure treatment apparatus, a catalyst for oxidizing and reducing malodorous components to change them into an odorless state is usually arranged in the air flow path.
[0033]
Conventionally, in this deodorizing apparatus, the steam is brought into contact with catalyst particles such as platinum or platinum while the steam is reheated and maintained at a high temperature. For this reason, it has been separated into a dedicated mechanism for reheating and a dedicated mechanism for holding the catalyst. For this reason, the evaporated water vapor was once heated by the reheating mechanism, contacted with the catalyst particles in the catalyst mechanism, contacted with the catalyst particles, oxidized and reduced, transformed into odorless, and diffused in the air. . In this mechanism, the two mechanisms are separated from each other independently, and the overall shape of the apparatus has to be large. Also, the catalyst must always be maintained at a constant temperature. This is because the function as a catalyst cannot be achieved unless the temperature is maintained above a specific temperature due to the nature of the catalyst. For this reason, when the reheating mechanism and the catalyst are located at a distance from each other, the thermal efficiency is deteriorated.
The invention of the present application pays attention to this point, and the catalyst particles and the heater are stored in the same sealed container, and the catalyst particles are heated by the heater so that the oxidation / reduction function can be exhibited. . Furthermore, the catalyst particles are arranged near the heater so that the thermal efficiency can be increased.

The processing operation can be automatically stopped.
[0140]
[[Input signal system to the central processing circuit 191]]
[0141]
The output signal of the liquid level sensor 181 described above is input to the overflow determination circuit 195, and the determination signal from the overflow determination circuit 195 is input to the central processing circuit 191. The output signal of the temperature sensor 180 that detects the temperature change of the drying pot 41 is input to the temperature determination circuit 196, and the determination signal from the temperature determination circuit 196 is input to the central processing circuit 191. A processing switch 183 is provided inside the house 13 for instructing the start of processing of manure excreted by a person using the temporary toilet 11 (not shown). An output signal from the processing switch 183 is input to the drying instruction circuit 197, and a determination signal from the drying instruction circuit 197 is input to the central processing circuit 191. The signal from the temperature sensor 143 is input to the overheat determination circuit 198, and the determination signal from the overheat determination circuit 198 is input to the central processing circuit 191. The output of the power switch 192 for starting the operation of the entire temporary toilet 11 is also input to the central processing circuit 191.
[0142]
[[Output signal system from the central processing circuit 191]]
[0143]
The central processing circuit 191 compares various input signals with conditions stored in advance as a program therein, and can operate various mechanisms provided in the urine processing device 15 according to the determination result. . For this reason, the central processing circuit 191 can output a plurality of control signals. A plurality of independent control signals are output from the central processing circuit 191. Each control signal is input to a use stop display circuit 193, a motor control circuit 201, an on-off valve control circuit 202, and a heater control circuit 203, respectively. Yes.
[0144]
The motor 108, the blower 145, and the motor 159 are independently connected to the output of the motor control circuit 201. Further, the output of the on / off valve control circuit 202 is connected to the on / off valve 124 and the switching valves 161 and 171, and the output of the heater control circuit 203 is connected to the heater 139 and the high frequency generation circuit 204. A high frequency coil 118 is connected to the output 204. A display lamp 194 is connected to the use stop display circuit 193.
[0145]
Next, the operation of the manure processing apparatus 15 provided in the temporary toilet 11 of the present embodiment will be specifically described by dividing it into each situation.
[0146]
<No operation>
[0147]
When the temporary toilet 11 is stored in a warehouse or the like, or when the temporary toilet 11 is installed at a venue, but is not used at night or on holidays, the power switch 192 is turned off (circuit In other words, each mechanism constituting the urine processing device 15 is maintained in a stopped state. When the power switch 192 is set to OFF, the central processing circuit 191 is maintained in a stopped state by the signal, and the central processing circuit 191 is connected to the motor control circuit 201, the on-off valve control circuit 202, and the heater control circuit 203, respectively. Sending a stop signal.
[0148]
In this stopped state, the motor control circuit 201 stops the motor 108, the blower 145, and the motor 159, respectively. The on-off valve control circuit 202 closes the on-off valves 124 and 171 and switches the switching valve 161 in a direction in which the air pipe 150 and the air supply pipe 125 communicate with each other. The heater control circuit 203 does not supply power to the heater 139 and the high frequency generation circuit 204, the heater 139 does not generate heat, and the high frequency coil 118 does not generate electromagnetic waves.
[0149]
<Standby by turning on the power>
[0150]
When the temporary toilet 11 is temporarily used at a construction site or a venue for the event, the mechanisms of the manure processing device 15 stored in the temporary toilet 11 are started up, and the user's excreta excreted in the toilet 16 is collected. It must be set in a standby state so that it can be processed immediately. In order to set the temporary toilet 11 to the “standby” state, the manager of the temporary toilet 11 or the person in charge at the event hall or the like turns on the power switch 192 (turns on the power). When the power switch 192 is turned on, the urine processing device 15 starts to operate, and is ready to start processing excreted excreta at any time. The central processing circuit 191 is switched to a state in which the motor control circuit 201, the on-off valve control circuit 202, and the heater control circuit 203 can be operated by the ON signal from the power switch 192.
[0150]
In this standby state, the heater control circuit 203 is passing a current through the heater 139 to cause the heater 139 to generate heat. The heat generated from the heater 139 heats the catalyst particles 133 through the inner cylinder 129. The reason why the catalyst particles 133 are heated in the standby state is that unless they are heated to a specific temperature, the oxidation / reduction function that is a characteristic of the catalyst does not occur. This is because 133 must be prepared so that it can be operated immediately. At the same time, the motor control circuit 201 starts the operation of a motor (not shown) housed in the blower 145. Then, the air blower 145 sucks air in the direction D from the intake pipe 146 opened on the side surface and discharges it in the direction of the eject pipe 147, and the discharged air flows in the inner space of the eject pipe 147 and passes through the opening end of FIG. It is ejected in the E direction. When air flows through the eject pipe 147, the air passes around the core pipe 148 provided in the middle of the eject pipe 147 at a high speed, and a negative pressure is generated around the discharge port 149. Therefore, the air inside the core pipe 148 is sucked by the negative pressure from the discharge port 149, and the air is discharged in the J direction in FIG. Since the core pipe 148 communicates with the air supply pipe 177 as shown in FIG. 17, the air inside the outer cylinder 127 is discharged via the discharge pipe 165 by discharging the air in the J direction. become.
[0151]
When air flows in the E direction in the eject pipe 147, a part of the air is taken in from the intake port 151 and flows into the air pipe 150. The air flows from the air pipe 150 into the lower space of the outer cylinder 127 through the intake joint 131 through the switching valve 161, the air supply pipe 125, and the evaporation pipe 164. Thus, the air inside the outer cylinder 127 is sucked from the exhaust joint 130 and blown from the intake joint 131, so that cold air flows into the outer cylinder 127 and circulates. The air is circulated in order to prevent the catalyst particles 133 heated by the heater 139 from becoming unnecessarily high. Thus, the temporary toilet 11 is maintained in a standby state.
[0152]
<Use of temporary toilet 11 by the user>
[0153]
Thus, when the power switch 192 is turned on, each mechanism of the urine processing device 15 is in a standby state, and the user can use the temporary toilet 11 at any time. In order to use the waiting temporary toilet 11, the user opens the door 14, enters the house 13, and excretes urine toward the toilet 16. The excreted excreta is received by the toilet 16 and temporarily stored here.
[0154]
<< Injection of manure into drying pot 41 >>
[0155]
Thus, when the user using the toilet 16 of the temporary toilet 11 presses the processing switch 183 provided in the house 13 after the defecation is finished, the urine of the toilet 16 is put into the drying pot 41 and dried. The process starts. When the processing switch 183 is pressed, the central processing circuit 191 opens an opening / closing valve (not shown), opens the lower part of the toilet 16, and causes the urine to flow downward. Then, the manure falls down the joint 80 and moves to the introduction pipe 79, flows through the slanted interior of the introduction pipe 79, and is put into the drying pot 41. A part of the manure adheres to the inner wall of the joint 80 and the introduction pipe 79, but when it is put into the drying pot 41, a small amount of washing water is sprayed onto the toilet bowl 16, and these adherence. It is also possible to allow the excreted manure to flow into the drying pot 41 together with the washing water. If the opening / closing valve of the toilet 16 is opened for a predetermined time and the washing water is injected, the central processing circuit 191 determines that all of the urine is charged, and closes the opening / closing valve.
[0156]
<< Usage restrictions for temporary toilet 11 >>
[0157]
Such charging of urine into the drying pot 41 is performed every time the user presses the processing switch 183 using the temporary toilet 11. However, if the urine is continuously input, the urine is finally input exceeding the capacity of the drying pot 41, and the next evaporation / drying process cannot be performed. For this reason, when the amount of manure injected into the drying pot 41 reaches a predetermined amount, the use of the temporary toilet 11 is stopped and the use by the user is restricted.
[0158]
That is, when the liquid level of the urine charged in the drying pot 41 rises and finally exceeds the amount that can store the urine in the drying pot 41, the liquid level of the urine comes into contact with the liquid level sensor 181. Thus, the electrodes of the liquid level sensor 181 are short-circuited. Then, this signal is transmitted to the overflow determination circuit 195, and the overflow determination circuit 195 notifies the central processing circuit 191 that the urine has been charged up to the limit of the processing capacity of the drying pot 41. Then, the central processing circuit 191 determines to temporarily limit the use of the temporary toilet 11, and outputs the determination signal to the use stop display circuit 193.
[0159]
Then, the use stop display circuit 193 turns on the display lamp 194 provided inside the temporary toilet 11, notifies the user that the drying pot 41 of the temporary toilet 11 has overflowed, and uses it until the display lamp 194 turns off. You will be warned not to. At the same time, the central processing circuit 191 does not operate the opening / closing valve of the toilet 16 and restricts the user from dropping the urine into the drying pot 41 even if the user excretes the urine into the toilet 16. By this operation, smooth evaporating / drying processing is performed without letting the drying pot 41 be charged with manure exceeding the processing capacity. The operation of restricting the use of the temporary toilet 11 is such that after the liquid level of the urine comes into contact with the liquid level sensor 181, a series of urine processing cycles described below is completed, and all the urine in the drying pot 41 is evaporated. Continue until you are allowed to.
[0160]
<Start of treatment for evaporation and drying of manure>
[0161]
As described above, when the processing switch 183 is pushed by the user and the excreted excreta is put into the drying pot 41, the central processing circuit 191 closes the opening / closing valve of the toilet bowl 16, and then the inside of the drying pot 41 The process of evaporation and drying of manure stored in In this process, the central processing circuit 191 transmits individual control signals to the motor control circuit 201, the on-off valve control circuit 202, and the heater control circuit 203 in accordance with the steps stored in advance, and instructs the evaporation / drying process. To do.
[0162]
In this evaporation / drying process, <switching the flow path>, <heating the drying kettle 41>, <deodorizing by the deodorizing unit 24>, <discharging air in the drying kettle 41 by the exhaust unit 25>, A series of operations of <rotational motion of the stirring unit 28> and <stirring of manure by the heat storage body 50> are performed. Each operation will be sequentially described below.
[0163]
<< Flow path switching >>
[0164]
When this evaporation / drying process is started, the central processing circuit 191 opens the on-off valve 124 by the on-off valve control circuit 202, and the switching valve 161 is in a state where the air pipe 150 and the air supply pipe 162 are in communication. Yes. However, the on-off valve 171 shown in FIG. 19 is kept closed. For this reason, the air taken in from the inlet 151 and flowing through the air pipe 150 flows into the drying pot 41 from the air supply pipe 162 and assists the oxidation of manure. Further, the water vapor and air evaporated from the drying pot 41 can pass through the on-off valve 124 and flow from the evaporation pipe 164 to the deodorizing unit 24.
[0165]
<< Heating of drying pot 41 >>
[0166]
When a control signal is input from the central processing circuit 191 to the heater control circuit 203, the heater control circuit 203 supplies power to the high frequency generation circuit 204, and causes the high frequency generation circuit 204 to supply high frequency power to the high frequency coil 118. When high frequency power is supplied to the high frequency coil 118 housed in the coil container 119, the high frequency coil 118 generates electromagnetic waves in the vertical direction, and the high frequency electromagnetic waves leak out of the coil container 119 and are stirred at a high frequency. To do. The high-frequency electromagnetic wave leaking from the coil container 119 passes through the bottom portion of the drying pot 41 that is close to the upper surface of the coil container 119, and the electromagnetic wave is agitated at the bottom portion of the drying pot 41.
[0167]
For this reason, an electromagnetic induction heating phenomenon occurs in the bottom portion of the drying kettle 41 by agitating high frequency electromagnetic waves (the drying kettle 41 is formed of a metal material such as iron). It generates heat. At the same time, the electromagnetic wave also agitates the heat storage body 50 housed in the drying pot 41, and the heat storage body 50 itself generates heat. Since the drying pot 41 and the heat storage body 50 generate heat by this electromagnetic induction heating, the manure stored in the drying pot 41 is heated by the drying pot 41 and the heat storage body 50, and the temperature rises. When the temperature of the manure rises in this way, the stored manure is finally heated to a boiling temperature, and water, which is a major component of the manure, becomes water vapor and evaporates from the surface.
[0168]
<< Deodorization by Deodorization Unit 24 >>
[0169]
As described above, since the heater control circuit 203 supplies power to the heater 139, the heater 139 generates heat at a high temperature. The heat generated by the heater 139 heats the catalyst particles 133 through the inner cylinder 129, and the catalyst particles 133 are maintained at a temperature sufficient to exhibit their oxidation / reduction functions. For this reason, the air flowing in the donut-shaped space inside the outer cylinder 127 and outside the inner cylinder 129 comes into contact with the catalyst particles 133 having a high temperature, and ammonia, bromine which are elements of odor contained in the air Etc. are oxidized and reduced to change to an odorless state.
[0170]
<< Release of Air in Drying Pot 41 by Exhaust Unit 25 >>
[0171]
As described above, the central processing circuit 191 operates a motor (not shown) housed in the blower 145 via the motor control circuit 201. For this reason, the air blower 145 sucks air from the intake pipe 146 opened on the side surface and discharges it in the direction of the eject pipe 147, and the released air flows in the inner space of the eject pipe 147 from the opening end in FIG. Ejected in the E direction. When air flows through the eject pipe 147, the air passes around the core pipe 148 provided in the middle of the eject pipe 147 at a high speed, and a negative pressure is generated around the discharge port 149. Therefore, the air inside the core pipe 148 is sucked by the negative pressure from the discharge port 149, and the air is discharged in the J direction in FIG. Since the core pipe 148 communicates with the air supply pipe 177 as shown in FIG. 17, air is sucked from the air supply pipe 177 when air is discharged in the J direction. Since the exhaust joint 130 is connected to the air supply pipe 177 via the discharge pipe 165, the air in the outer cylinder 127 is sucked from the exhaust joint 130, and the air is exhausted from the intake joint 131 in FIG. Flowing into. Since the intake joint 131 communicates with the inside of the drying pot 41 via the evaporation pipe 164 and the opening / closing valve 124, as a result, the air inside the drying pot 41 flows in the order of the opening / closing valve 124, the evaporation pipe 164, and the intake joint 131. Sucked up.
[0172]
In such a flow of air, the air flowing into the outer cylinder 127 from the intake joint 131 passes through the filter 134 and flows in the direction of the catalyst particles 133 maintained at a high temperature by the heater 139. The water vapor and air evaporated from the drying kettle 41 contain elements that cause bad odors such as ammonia and bromine, and cannot be released to the outside as they are. However, when the air from the drying kettle 41 comes into contact with the surface of the catalyst particles 133, these malodorous elements come into contact with the catalyst such as platinum and rhodium constituting the catalyst particles 133, and the malodorous elements are oxidized and reduced and are odorless. Transformed into a state. Next, this air flows through the discharge pipe 165 and the air supply pipe 177, is mixed with the air from the blower 145 inside the eject pipe 147, and is diffused to the outside air from the open end of the eject pipe 147.
[0173]
Note that the air in the drying pot 41 is sucked in the direction of the eject pipe 147, but the same amount of air as that discharged must be newly introduced into the drying pot 41. When the air flows in the above-described eject pipe 147, the air flows into the intake port 151 of the air pipe 150 located at the end of the eject pipe 147, and a part of the discharged air flows through the air pipe 150. The air flowing in the air pipe 150 passes through the switching valve 161 and the air supply pipe 162, and then flows into the drying pot 41 through the air hole 54 opened in the upper surface of the holding plate 35. This fresh air promotes the oxidation of manure stored in the drying pot 41.
[0174]
<< Rotational motion of stirring unit 28 >>
[0175]
Further, the central processing circuit 191 outputs a control signal to the motor control circuit 201, starts the operation of the motor 108 by the motor control circuit 201, and causes the motor 108 to rotate the stirring unit 28. When electric power is supplied to the motor 108, the rotation output of the motor 108 is decelerated through the gear box 109, and the output shaft 110 at the upper end is rotated at a low speed. Then, the pulley 113 fixed to the output shaft 110 also rotates at the same time, and the pulley 85 is driven via the belt 114 as shown in FIGS. 5 and 7, and the drive fixed to the center by the rotation of the pulley 85. The shaft 66 is rotated in the horizontal direction (the pulley 85 and the drive shaft 66 are engaged with the key 87 as shown in FIGS. 10 and 11, so that the slip is not generated in the horizontal direction and is synchronized as it is. And rotate). As shown in FIGS. 10 and 11, since the upper and lower sides of the drive shaft 66 are rotatably held by the outer shaft cylinder 66 by bearings 74 and 81, the drive shaft 66 rotates smoothly in the horizontal direction. In this way, when the pulley 85 is driven via the belt 114, the rotational force is transmitted to the drive shaft 66 via the key 87, and the pulley 85 and the drive shaft 66 are simultaneously rotated in the same direction. .
[0176]
Since the stirring unit 28 is suspended below the drive shaft 66 as shown in FIGS. 7 and 12, the entire stirring unit 28 rotates in the horizontal direction together with the drive shaft 66. In this rotation operation, a connecting plate 95 is connected to a connecting plate 68 fixed to the lower end of the drive shaft 66, and the connecting plate 95 is a crank composed of a suspension pipe 97, a slanting pipe 98 and a suction pipe 99. Since these pipes are suspended, these pipes rotate in synchronization with the drive shaft 66 inside the drying pot 41. In addition, the suction pipe 99 is close to the inner wall of the drying pot 41 as shown in FIGS. 6 and 7, and the suction pipe 99 draws a circular locus in the drying pot 41 with the drive shaft 66 as the center of rotation. Will rotate. The lower end opening of the suction pipe 99 rotates with an interval that does not contact the bottom surface of the drying pot 41.
[0177]
When the suction pipe 99 rotates, the triangular plates 100 and 101, the stirring plate 104, and the skirt plate 105 connected to the side surface of the suction pipe 99 simultaneously rotate in a circular manner in the drying pot 41. In the rotation of the stirring plate 104 and the skirt plate 105, as shown in FIG. 6, the stirring plate 104 and the skirt plate 105 rotate in that form while dividing the space of the drying pot 41 into two sides. The end rotates so as not to come into contact with the inner wall of the drying pot 41 at a slight distance, and the lower end of the skirt plate 105 rotates so as not to contact with the bottom of the drying pot 41 at a slight distance. For this reason, as shown in FIG. 6, the stirring plate 104 and the skirt plate 105 rotate so as to stir the manure inside the drying pot 41, and at the same time, while pressing the heat storage body 50 accommodated in the drying pot 41, Will be moved.
[0178]
<< Agitation of manure by the heat storage body 50 >>
[0179]
As described above, when the motor 108 is operated, the entire stirring unit 28 is rotated by the rotational force, and the heat accumulator 50 put into the drying pot 41 by the stirring plate 104 and the skirt plate 105 is rotated inside the drying pot 41. Will be moved. Since the urine stored in the drying kettle 41 is stirred by the stirring plate 104 and the skirt plate 105 and the heat storage body 50 is rolled at the same time, the manure stored in the drying pot 41 is stirred by the stirring plate 104, the skirt plate 105 and the heat storage body 50. And stirred until the temperature of the whole manure is uniform. In this stirring and rolling operation, manure is sequentially attached to the surface of each heat storage body 50, and the heat generated by the heat storage body 50 is transmitted to the manure, thereby performing an auxiliary function of raising the temperature of the manure. . Thus, the temperature of the entire manure is increased by transmitting the temperature at which the manure is heated while being stirred by the heat storage body 50.
[0180]
As shown in the cross-sectional view of FIG. 7, a protrusion 43 having a raised center is formed at the center of the bottom of the drying pot 41. Since the protrusion 43 is located at the center of the bottom of the drying pot 41, when the plurality of heat storage bodies 50 roll inside the drying pot 41, the heat storage body 50 slides down the slope of the protrusion 43. The heat accumulator 50 rolls around the drying pot 41 without being collected at the center of the drying pot 41. For this reason, even if a plurality of heat storage elements 50 roll, the respective heat storage elements 50 do not collect in a dumpling form at the center of the drying pot 41 and always roll near the bottom around the drying pot 41. , Urine can be reliably stirred.
[0181]
<End of Evaporation / Drying Process of Dry Manure by Drying Pot 41>
[0182]
In this way, by rotating the stirring unit 28 while heating the drying kettle 41 and the heat storage body 50 by the high frequency coil 118, the manure stored in the drying kettle 41 continues to boil, and most of the components constituting the manure This moisture will continue to evaporate. When this evaporation operation is continued, all of the manure stored in the drying pot 41 is evaporated. If all of the manure in the drying pot 41 has evaporated, there is no need to continuously heat the drying pot 41 and the heat storage body 50 with the high-frequency coil 118, and the evaporation / drying process must be completed. The end of this process can be detected by the temperature sensor 180.
[0183]
When all of the manure stored in the drying kettle 41 is dried, the temperature of the drying kettle 41 has been maintained near the boiling point because the manure has been evaporated until then. However, since no manure that absorbs heat is lost, the drying kettle 41 The temperature will rise rapidly. The temperature of the drying kettle 41 is always detected by the temperature sensor 180. When the temperature of the outside of the drying kettle 41 rises rapidly due to evaporation of the manure, this temperature change is detected by the temperature sensor 180. A temperature change detection signal from the temperature sensor 180 is transmitted to the temperature discrimination circuit 196, and the temperature discrimination circuit 196 discriminates that all the urine in the drying pot 41 has been evaporated. A discrimination signal from the temperature discrimination circuit 196 is output to the central processing circuit 191. The central processing circuit 191 stops the evaporation / drying process and instructs the next cleaning process.
[0184]
<< Stopping heating of drying pot 41 >>
[0185]
The central processing circuit 191 outputs a signal for stopping the operation to the heater control circuit 203, whereby the heater control circuit 203 stops supplying power to the heater 139 and the high-frequency generation circuit 204. Therefore, the heater 139 stops generating heat, and the high-frequency generation circuit 204 stops supplying high-frequency power to the high-frequency coil 118 and heating of the drying pot 41 and the heat storage body 50 is stopped. Even if heating by the heater 139 and the high frequency coil 118 is stopped, the central processing circuit 191 maintains the control signal to the motor control circuit 201, and the motor 108 and the blower 145 still continue to operate as before. is doing.
[0186]
<Start of cleaning process>
[0187]
Next, the central processing circuit 191 starts the cleaning process according to the procedure of the program stored in advance. As described above, when the urine is evaporated and dried in the drying pot 41, most of the moisture, which is a component, evaporates, but organic matter and inorganic matter contained in the urine remain as dust. If such dust accumulates in the drying pot 41, it will remain attached to the inner wall and bottom of the drying pot 41, and the stirring plate 104, the skirt plate 105, and the heat accumulator 50 may remain in the drying pot 41 depending on the use for many years. It becomes impossible to rotate, and finally the function of the temporary toilet 11 will not be performed. For this reason, if the process of evaporation / drying of manure is completed, then a cleaning process must be performed to remove dust remaining in the drying pot 41.
[0188]
In this cleaning processing operation, the central processing circuit 191 outputs a control signal to the motor control circuit 201 to start the operation of the motor 159, and at the same time outputs a control signal to the on-off valve control circuit 202 to turn on the on-off valve 171. The opening / closing valve 124 is closed. When the motor 159 is operated, the fan 174 built in the suction machine 157 starts to rotate, sucks the air in the collection box 152, discharges it in the direction of the discharge pipe 158, and discharges it in the G direction in FIG. . Then, due to the suction of air by the fan 174, the inside of the collection box 152 becomes negative pressure through the filter 156, and the air is sucked into the collection box 152 from the introduction pipe 154.
[0189]
For this reason, the air in the drying pot 41 is sucked from the lower end opening of the suction pipe 99, flows through the suction pipe 99, the oblique pipe 98 and the suspension pipe 97, and then the ventilation hole 67 opened in the center of the drive shaft 66. Passes through the on-off valve 171, the dust suction pipe 172, and the introduction pipe 154 and flows into the garbage bag 155. The air that has passed through the garbage bag 155 flows into the internal space of the collection box 152, passes through the filter 156, passes through the suction machine 157, the discharge pipe 158, the air supply pipe 175, the check valve 176, and the air supply pipe 177. , Flows into the core pipe 148. Then, the air reaching the core pipe 148 is sucked from the discharge port 149 by the ejector effect by the exhaust part 25 as described above, and is discharged from the opening of the eject pipe 147 to the outside air. In this way, a series of air flow paths from the suction pipe 99 to the discharge pipe 142 is formed.
[0190]
When air is sucked from the lower end opening of the suction pipe 99 and flows in the direction of the recovery box 152, the lower end opening of the suction pipe 99 is close to the bottom surface of the drying pot 41. The remaining dust due to organic matter or inorganic matter that cannot be evaporated is sucked together with air from the lower end opening of the suction pipe 99. The dust sucked together with the air is caused to flow into the garbage bag 155 according to the above-described route. In this garbage bag 155, the air passes through the film surface, but the dust is caught by the fine mesh on the film surface and captured. The For this reason, the dust bag 155 separates dust from the air that has flowed in, and passes only clean air through the internal space of the collection box 152. The dust bag 155 captures dust remaining in the drying pot 41. Is done.
[0191]
At this time, the motor 108 continues to operate following the evaporation / drying process, and the entire agitating unit 28 moves like a miso-scrubbing motion in the drying pot 41 via the pulley 113, the belt 114, and the pulley 85. It is rotating with a circular trajectory. For this reason, the lower end opening of the suction pipe 99 rotates in a circular shape at the bottom of the drying pot 41, and the dust accumulated on the bottom of the drying pot 41 is sucked up evenly. Further, when the stirring unit 28 rotates, the stirring plate 104 and the skirt plate 105 also rotate at the same time, causing the heat storage body 50 to roll at the bottom portion of the drying pot 41, so that the heat storage body 50 causes the bottom of the drying pot 41 to move. The dust that has accumulated is peeled off and finely crushed, and the dust that has accumulated on the bottom of the drying pot 41 is peeled off and finely crushed so as to be easily sucked together with air.
[0192]
In this way, the dust sucked up from the lower end opening of the suction pipe 99 is captured by the garbage bag 155, and the clean air that has passed through the membrane surface of the garbage bag 155 passes through the filter 156, and the air supply pipe is passed through the above-described path. 177. In this flow of air, the check valve 176 opens inside the check valve 176 and allows the flow of air from the air supply pipe 175 to the air supply pipe 177. Therefore, the air smoothly flows in this flow direction. Will flow. The cleaned air discharged from the air supply pipe 177 to the core pipe 148 is sucked at the discharge port 149 (the blower 145 continues to the heating / drying process and continues. The exhaust pipe 141 and the core pipe 148 flow in this order, and are mixed with the flowing air through the eject pipe 147 and discharged from the open end of the eject pipe 147 to the outside air.
[0193]
<Stopping the cleaning process>
[0194]
As described above, when the cleaning process by sucking the dust accumulated in the drying pot 41 is operated for a predetermined time, the dust stored in the bottom portion of the drying pot 41 is stored in the garbage bag 155. Captured and the cleaning process is complete. Then, the temporary toilet 11 must automatically stop the cleaning process and return to the initial state. This is because the temporary toilet 11 must then be used to wait for the user to be excreted in the toilet 16.
[0195]
In stopping the cleaning process, the central processing circuit 191 makes a self-judgement and determines a stop signal when a predetermined time has elapsed from the start of the cleaning process according to a program stored in the central processing circuit 191 in advance. Is output. For this reason, the central processing circuit 191 outputs a control signal to the motor control circuit 201, stops the operation of the motor 159, stops the suction of air by the fan 174, and sucks the air from the drying pot 41 by the suction pipe 99. Stop. At the same time, the central processing circuit 191 also outputs a control signal to the on-off valve control circuit 202, and closes the on-off valve 171 connecting the vent hole 67 and the dust suction pipe 172. As a result, the air flow path extending from the lower end opening of the suction pipe 99 to the front end opening of the discharge pipe 142 is closed, the air and dust no longer flow, and the cleaning process is stopped.
[0196]
The series of processing operations so far are continued even if the power switch 192 is turned off halfway. This is because once the manure is put into the drying kettle 41, one processing cycle must be completed and all the manure in the drying kettle 41 must be evaporated unless a part of the apparatus breaks down. . If the power switch 192 is turned off due to carelessness of the worker in the middle of the process and the <evaporation / drying process> is stopped, the manure remains in the drying pot 41 and is used for the next use. This is inconvenient.
[0197]
<Do you want to start the next processing cycle?>
[0198]
In this manner, if <cleaning process> and <cleaning process stop are performed following <evaporation / drying process>, the operation of the temporary toilet 11 is stopped or the process proceeds to the next processing cycle. Further, it is determined whether the cleaning operation of the catalyst body 140 is performed. The operation of the temporary toilet 11 is stopped based on whether or not the power switch 192 is turned off. If the processing has progressed to this point and the power switch 192 is turned off, the central processing circuit 191 stops all operations of the temporary toilet 11. However, even if the processing cycle is in progress, if the power switch 192 is turned on, the processing cycle returns to the above-described <evaporation / drying processing>, and the effect of evaporating the manure again is performed. . When the central processing circuit 191 determines that the catalyst body 140 must be cleaned, the operation shifts to the cleaning process.
[0199]
<Re-evaporation / drying of manure>
[0200]
When the above-mentioned <stop of cleaning process> is completed and the power switch 192 is turned on, and the user who next uses the temporary toilet 11 presses the process switch 183 to turn it on, the central processing circuit 191 Again, start the <evaporation / drying process> for urine and continue the next processing cycle. In this process, control signals are output from the central processing circuit 191 to the on-off valve control circuit 202 and the heater control circuit 203, respectively, as described above, and a predetermined amount of manure is injected into the drying pot 41 as described above. The urine is evaporated and dried in the drying pot 41. The cycle of this process is the cycle of <switching of the flow path>, <evaporation / drying process>, <cleaning process>, <stop of cleaning process>, and <determination of stop of processing cycle> as described above. This processing cycle is continuously repeated unless the power switch 192 is turned off.
[0201]
<Preventing overheating of heater 139>
[0202]
As described above, the heater 139 is energized and generates heat by itself to overheat the catalyst particles 133. However, if energization of the heater 139 is continued, the temperature of the heater 139 itself becomes high, causing disconnection. In order to prevent the heater 139 from reaching an extremely high temperature, air from the intake port 151 is caused to flow into the outer cylinder 127 and cold air is circulated. However, even in this cooling with air, the balance between heat generation and heat dissipation may be lost, and it is not always possible to prevent the temperature of the heater 139 from becoming high due to air cooling. For this reason, the temperature sensor 143 inserted in the center of the heater 139 constantly detects the temperature and outputs the signal to the overheat determination circuit 198. If the heater 139 becomes higher than a preset temperature, the overheat determination circuit 198 determines that a dangerous temperature has been reached based on a signal from the temperature sensor 143, and transmits the signal to the central processing circuit 191. Then, the central processing circuit 191 outputs a control signal to the heater control circuit 203, stops the supply of electric power to the temporary heater 139, and suppresses the temperature from rising further. Further, when the temperature sensor 143 decreases the temperature of the heater 139 and falls below the temperature at which the function of the catalyst particles 133 is exerted, the signal is transmitted to the overheat determination circuit 198 and, contrary to the above, from the heater control circuit 203. Control is performed to increase the temperature by supplying power to the heater 139. In this way, since the temperature of the heater 139 is controlled, the catalyst particles 133 can be kept at a constant temperature and can be set to a temperature at which the oxidation / reduction function can be exerted, and the heater 139 is not disconnected. To maintain.
[0203]
<Return to standby state>
[0204]
In this way, the treatment cycle of manure repeats <evaporation / drying process>, <cleaning process>, <stop of cleaning process>, and <determination of stop of processing cycle>. When there are no users who use the temporary toilet 11 (for example, when it is nighttime or a holiday and there are no users), the power switch 192 is turned on after the operation of <Stop Cleaning Process>. It is a condition that is turned on, and the temporary toilet 11 shifts to a standby state without shifting to the normal processing cycle. That is, when the processing switch 183 is not turned on and <stop of cleaning processing> is entered, the central processing circuit 191 does not shift to the cycle for treating urine but stops the entire temporary toilet 11 Let me wait. This standby state is the same as the start of the process at the beginning.
[0205]
Therefore, the central processing circuit 191 outputs a control signal to the motor control circuit 201 and stops the operation of the motor 108. Then, the stirring unit 28 rotated in the drying pot 41 is stopped by the driving force of the motor 108, and the stirring plate 104, the skirt plate 105, and the heat storage body 50 stop rotating (the heater control circuit 203 is < During the cleaning process>, the heater 139 does not generate heat because the supply of power to the heater 139 and the high-frequency generation circuit 204 is stopped, and since the high-frequency power is not supplied to the high-frequency coil 118, drying is performed. The pot 41 is not heated). This standby state continues until the user excretes urine from the toilet 16 and the user turns on the processing switch 183. When the power switch 192 is turned off in this standby state, the temporary toilet 11 stops all of its functions.
[0206]
<Stopping operation of temporary toilet 11>
[0207]
The operation of the temporary toilet 11 can be stopped by turning off the power switch 192. For example, it may not be necessary to treat urine at night in a temporary site or a venue, or the temporary toilet 11 may be stored in a warehouse or the like from the installation location. In such a case, the operation of the temporary toilet 11 as a whole is stopped by the manager or worker who manually turns off the power switch 192. However, as described above, even when the processing cycle such as <evaporation / drying processing> or <cleaning processing> is continued, even if the power switch 192 is turned off, the processing in that cycle continues once. The operation is not stopped until this processing cycle is completed. When the processing cycle ends, the function of the temporary toilet 11 stops.
[0208]
<Flowchart showing processing cycle>
[0209]
An outline of a series of operations for the treatment of manure by the temporary toilet 11 is shown in FIGS. The flowcharts shown in FIG. 21 and FIG. 22 show a large operation in the processing cycle described above, from the stop state of the temporary toilet 11 until the power switch 192 is turned off to stop the operation. .
[0210]
<Truth table during processing cycle>
[0211]
FIG. 23 is a truth table showing the operation of each mechanism in each processing situation in an operation cycle.
[0212]
Next, FIGS. 22 and 23 show another embodiment of the present invention. FIG. 22 is a cross-sectional view showing the configuration of the deodorizing unit 24 cut in the vertical direction and showing its configuration from the side, and FIG. 23 is an exploded perspective view showing a state before the members constituting the deodorizing unit 24 are separated and assembled. FIG.
[0213]
The entire appearance of the deodorization part 24 is cylindrical, and has a structure in which a double space is formed inside, and is sealed airtight from the outside, and the deodorization part 24 is decomposed into three parts. It has a structure that can. The outer shell which becomes the center of the deodorization part 24 consists of the cylindrical outer cylinder 210, is formed of a thin steel plate or the like, and the inside is hollow so that air can flow. An exhaust joint 213 communicating with the inside of the outer cylinder 210 is connected to the lower side surface of the outer cylinder 210 at a right angle, and a thin bottom plate 211 is fitted in the opening at the bottom of the outer cylinder 210. Has an outer diameter the same as the inner diameter of the outer cylinder 210, and has a ring shape with a circular opening at the center. The outer periphery of the bottom plate 128 and the inner periphery of the outer cylinder 127 are connected in an airtight manner by welding or the like.
[0214]
An inner cylinder 212 is inserted into the central opening of the bottom plate 211 from below, and the upper end of the inner cylinder 212 extends so as to protrude upward from the upper end opening of the outer cylinder 210, and the lower end of the inner cylinder 212. Is set to a length that slightly protrudes from the lower surface of the bottom plate 211. The inner cylinder 212 is formed of a thin steel plate and is formed into a hollow cylindrical shape. The inner cylinder 212 is shaped like a test tube with its upper part closed and opened downward. The outer diameter of the inner cylinder 212 is the bottom plate 211. Is set to be substantially the same as the inner diameter of the central opening. The opening of the bottom plate 211 and the outer periphery of the inner cylinder 212 are hermetically connected by welding or the like. Due to this configuration, the inner space of the outer cylinder 210 is partitioned by the inner cylinder 212 and sealed in a donut shape. A new space is formed. That is, the odor eliminating part 24 is formed of a cylindrical outer cylinder 210 and a cylindrical inner cylinder 212, and the skeleton is formed into two parts separated into a ring-shaped space and an inner space of the inner cylinder 212. It has a sealed structure with a room.
[0215]
A ring-shaped net bottom plate 214 is inserted between the inner circumference of the outer cylinder 210 and the outer circumference of the inner cylinder 212, and this net bottom plate 214 is installed at a position slightly higher than the upper opening of the exhaust joint 213. The outer cylinder 210 and the inner cylinder 212 are welded and fixed to the inner periphery. The mesh bottom plate 214 is formed by weaving thin stainless steel wires and has a structure that allows air to flow up and down. A donut-shaped space formed by the inner periphery of the outer cylinder 210 and the outer periphery of the inner cylinder 212 is filled with first catalyst particles 228 obtained by processing platinum, platinum, or the like into particles. 228 is supported by a net bottom plate 214. The upper ends of the filled first catalyst particles 228 are packed up to the upper end opening of the outer cylinder 210.
[0216]
A flange 215 protruding outward is formed on the outer periphery of the upper end opening of the outer cylinder 210 described above, and the lower end opening of the intermediate cylinder 217 is placed on the upper end opening of the outer cylinder 210. The intermediate cylinder 217 has a thin cylindrical shape with the same inner and outer diameters of the outer cylinder 210, and a flange 218 protruding outward is formed on the outer periphery of the lower end opening of the intermediate cylinder 217. In a state where the outer cylinder 210 and the intermediate cylinder 217 are in contact with each other vertically, a pair of half-moon shaped clamp bands 216 in which grooves are formed on the inner peripheral surface from the outer periphery of both flanges 215 and 218 are engaged from the left and right. With the clamp band 216, the outer cylinder 210 and the intermediate cylinder 217 are connected in an airtight manner. In the outer cylinder 210 and the intermediate cylinder 217 assembled in this way, the upper part of the inner cylinder 212 is concentrically arranged in the internal space of the intermediate cylinder 217, thereby forming a donut-shaped space. In this space, a particle cage 231 as a pulley-like housing is inserted from the upper part of the inner cylinder 212, and the upper and lower sides of the intermediate cylinder 217 are partitioned by the particle basket 231. The particle basket 231 is made of a net-like material knitted with a stainless steel wire, and can flow air in the vertical direction. The periphery of the particle cage 231 is filled with particulate second catalyst particles 229. The second catalyst particles 229 are partitioned by the inner periphery of the intermediate cylinder 217, and the upper and lower sides are held by the particle cage 231. Therefore, the second catalyst particles 229 can be removed from the inner cylinder 212 together with the particle basket 231 and the intermediate cylinder 217. This is because when the second catalyst particles 229 are washed or removed, the particle basket 231 and the intermediate cylinder 217 are unitized so that they can be easily taken out.
[0217]
A flange 219 protruding outward is formed on the outer periphery of the upper end opening of the intermediate cylinder 217, and a cylindrical upper cylinder 220 is placed on the upper end opening of the intermediate cylinder 217. The upper cylinder 220 has a thin cylindrical shape that is open at the top and bottom. The inner and outer diameters of the upper cylinder 220 are set to be the same as the inner and outer diameters of the intermediate cylinder 217, and the outer periphery of the lower end opening projects outward. A flange 221 is formed. A pair of half-moon shaped clamp bands in which the lower end opening of the upper cylinder 220 is brought into close contact with the upper end opening of the intermediate cylinder 217 and the outer circumferences of both flanges 221 and 219 are formed with grooves on the inner peripheral surfaces. 213 is engaged from the left and right. The upper cylinder 220 is connected to the intermediate cylinder 217 by the clamp band 213. A pipe-shaped exhaust joint 224 is connected to the side surface of the upper cylinder 220 at a right angle, and the exhaust joint 224 communicates with the internal space of the upper cylinder 220. In a state where the upper cylinder 220 is placed on the intermediate cylinder 217, the upper end of the inner cylinder 212 is set to be slightly lower than the lower opening of the exhaust joint 224.
[0218]
Thus, a donut-shaped space is formed between the inner periphery of the upper tube 220 and the outer periphery of the inner tube 212, and a filter 230 formed by rolling a metal net is inserted into this space. Further, a flange 222 protruding outward is formed on the outer periphery of the upper end opening of the upper cylinder 220, and a disc-shaped upper cover plate 225 is in close contact with the upper end opening of the upper cylinder 220. A pair of half-moon shaped clamp bands 226 with grooves formed on the inner peripheral surface are engaged with the outer periphery of the flange 222 and the upper cover plate 225 from the left and right sides, and the flange 222 and the upper cover plate 225 are hermetically sealed by the clamp band 226. It is connected.
[0219]
A flange 232 projecting outward is formed on the outer periphery of the lower end of the inner cylinder 212 described above, and a disc-shaped bottom cover plate 233 is in close contact with the lower end opening of the inner cylinder 212. A pair of clamp bands 234 formed with grooves on the inner peripheral surface are engaged with the outer periphery of the flange 232 and the bottom cover plate 233 from both the left and right sides, and the bottom cover plate 233 is hermetically sealed with the inner cylinder 212. It is connected to. A spiral heater 235 is inserted into the inner space of the inner cylinder 212, and the total length of the heater 235 is set to be slightly longer than the length from the lower part of the first catalyst particle 228 to the upper part of the second catalyst particle 229. It is. Both ends of the heater 235 extend downward from the lower surface of the bottom cover plate 233 to serve as power lines 237 for supplying power. A temperature sensor 236 for detecting the temperature change is inserted in the center of the lower part of the heater 235, and a sensor cable 238 connected to the temperature sensor 236 and outputting an electric signal passes through the bottom cover plate 233. And it is extended downward. These bottom cover plate 233, heater 235, power line 237, temperature sensor 236, and sensor cable 238 are assembled as one unit.
[0220]
In this way, the outer cylinder 210, the inner cylinder 212, the intermediate cylinder 217, the upper cylinder 220, and the upper cover plate 225 are assembled into an integral structure having a cylindrical appearance. Since the hollow inner cylinder 212 is positioned concentrically, a double space that is airtight from the outside is divided. In this configuration, the entire deodorizing unit 24 can be decomposed into three elements, and the work becomes easy when the first catalyst particles 228 and the second catalyst particles 229 are cleaned or replaced. . In this embodiment, water vapor and air containing bad odors flow into the inner space of the upper cylinder 220 from the exhaust joint 224, pass through the filter 230, and then contact the second catalyst particles 229. In contact with the second catalyst particles 229, ammonia, bromine and the like, which are elements of malodor contained in water vapor and air, are oxidized and reduced. Next, water vapor and air flow into the outer cylinder 210 and come into contact with the surface of the first catalyst particles 228 in the inner space of the outer cylinder 210. The first catalyst particles 228 are composed of particles having different shapes of the second catalyst particles 229, or are composed of catalysts having different compositions. Therefore, the second catalyst particles 229 cannot be oxidized / reduced. The element of can also be changed odorless. Then, the water vapor and air pass through the net bottom plate 214, flow to the lower space of the outer cylinder 210, and are then discharged to the outside from the exhaust joint 213.
[0221]
【The invention's effect】
As described above, according to the first aspect of the present invention, the space between the inner cylinder and the outer cylinder is formed in a space sealed from the outside, and the catalyst is inserted into this space. Since a heater capable of generating heat is inserted inside the inner cylinder, when the heater generates heat, the heat heats the catalyst through the inner cylinder. For this reason, the catalyst is maintained at a temperature sufficient to exhibit its function by the heater, and can exhibit the function of oxidation / reduction. And since the heat from a heater is directly transmitted to a catalyst via an inner cylinder, thermal efficiency becomes very high. Further, since the heating mechanism and the catalyst container are accommodated in the same mechanism, the volume of the entire apparatus is reduced, and it can be accommodated even in a small manure treatment apparatus.
[0222]
According to the invention of claim 2 of the present application, a donut-shaped space is formed between the inner cylinder and the outer cylinder, and the catalyst is accommodated in this space. The upper opening of the outer cylinder is closed by a cover plate. By removing the cover plate, the catalyst can be taken out, and the catalyst can be easily cleaned and replaced.
[0223]
According to the invention of claim 3 of the present application, the heater housed in the inner cylinder has a spiral shape, the base portion is held by the lower lid plate, and the heater and the lower lid plate are configured as an integral unit. is there. For this reason, when the heater is stored in the inner cylinder or pulled out, the lower cover plate can be assembled together, and the lower cover plate closes the lower opening of the inner cylinder while the heater is stored in the inner cylinder. Become. Assembling becomes easy, and work for exchanging the heater in inspection or the like is simplified.
[0224]
According to invention of Claim 4 of this application, an outer container is comprised by the outer cylinder, the intermediate | middle cylinder, the upper cylinder, and the cover plate, and can isolate | separate each separately. And a 1st catalyst and a 2nd catalyst can be separately accommodated in the inside of an outer cylinder and an intermediate cylinder, respectively. For this reason, it is possible to dispose the catalysts having different potencies separately and to exhibit the ability of oxidation / reduction in a dispersed manner. And since an intermediate | middle cylinder and an upper cylinder can be removed separately, each catalyst can be inserted or removed, and the operation | work of cleaning and a maintenance becomes easy.
[0225]
According to invention of Claim 5 of this application, the 2nd catalyst can be hold | maintained to the inside of an intermediate | middle cylinder by the pinch-shaped housing formed with the wire net. For this reason, when only the intermediate cylinder is removed or assembled, the second catalyst can be replaced while being held in the casing, and the second catalyst is not dispersed.
[0226]
According to the invention of claim 6 of the present application, the heater is accommodated in the inner cylinder. However, the temperature sensor can be accommodated simultaneously with the heater, and the temperature rise of the heater can be constantly observed. If the heater is overheated more than necessary, there is a risk of disconnection, but the temperature sensor can be controlled so as not to rise above an unnecessary temperature. For this reason, disconnection of the heater can be prevented and the heater can be used for a long time.
