Description

Solid-liquid separation device, urination dryer, and toilet equipment equipped with these devices

The present invention relates to a solid-liquid separation device, a urinal drying device, and a toilet equipment equipped with these devices.

Patent Document 1 discloses a conventional solid-liquid separation device. This solid-liquid separation device is configured by arranging a roller conveyor in which a plurality of rollers are connected in a slanted state. This solid-liquid separation device is provided below the outlet of the toilet bowl and separates human excrement into a solid content of stool and a liquid content of urine. That is, when waste drops from the toilet discharge port onto the roller conveyor, the stool descends on the roller conveyor. On the other hand, the urine drops downward from the gap between the rollers of the roller conveyor. Thus, this solid-liquid separation device can separate human excrement into stool and urine, and can transport stool.

A conventional urine dryer is shown in FIG. 3 of U.S. Pat. The urine drying apparatus includes a plate-like absorber and a feeding device for dropping urine from above the absorbent member using a pump. In this stool drying apparatus, by making the absorbent member have a large surface area, it is possible to well carry out the vaporization of the urine from the absorbent member.

JP 2005-143718 A Japanese Patent Laid-Open No. 2000-41892

However, in the solid-liquid separation device of Patent Document 1, there is a possibility that the space between the rollers of the roller conveyor may be filled with stool. When the space between the rollers of the roller conveyor is filled with stool, it is difficult for the urine to fall downward from the gap between the rollers, resulting in insufficient solid-liquid separation and smooth rotation of the rollers. As a result, the delivery of stools may not be performed well.

Moreover, in the urine drying apparatus of patent document 2, an absorber is plate shape and in order to ensure the surface area, the absorber is enlarged. For this reason, a space is required for installation of an absorber. Also, a pump is used to drip the urine onto the absorber and a power supply is needed for that.

The present invention has been made in view of the above-described conventional circumstances, and it is a solid-liquid separation device capable of favorably performing solid-liquid separation and solid content transportation, and effectively utilizing space without using a power source for urination. It is an issue to be solved to provide a urine drying apparatus which can be evaporated well and a toilet facility equipped with these apparatuses.

The solid-liquid separation device of the present invention is a solid-liquid separation device that separates solid-liquid mixtures such as human excrement, livestock manure and household garbage into solid and liquid components, and
A flat plate-like separation plate provided with an opening for receiving the solid-liquid mixture on the upper surface and passing the liquid portion downward;
A transport mechanism for pushing out the solid portion remaining on the separating plate from one end of the separating plate;
And a removing member for removing the solid matter adhering to the opening or closing the opening.

In this solid-liquid separator, when the solid-liquid mixture is received on the upper surface of the separating plate, the liquid component passes downward from the opening provided in the separating plate. On the other hand, the solid content remains on the separating plate and is pushed out from one end of the separating plate by the transport mechanism. The opening of the separating plate is maintained so that the liquid always passes because the removing member removes the solid even if the solid adheres or closes.

Therefore, the solid-liquid separation device of the present invention can perform solid-liquid separation and solid content transportation well.

The opening provided in the separating plate is formed in a slit shape extending from the one end to the other end of the separating plate, and the removing member is inserted into the opening in the state of being inserted into the opening. It can reciprocate along. In this case, by moving the removing member back and forth, it is possible to remove well the solid adhering to the opening or closing the opening, and the opening can pass the liquid well.

The transport mechanism reciprocates between the one end and the other end of the separation plate, and includes a strip-shaped extrusion plate extending in a direction perpendicular to the moving direction, and the extrusion plate The removing member may be connected and integrated. In this case, by reciprocating the extrusion plate and the removal member together between one end and the other end of the separating plate, the solid on the separating plate is pushed out from the one end and attached to the opening or the opening Solids which close the part can be removed well.

The push-out plate may be pivotally supported so as to rotate rearward with respect to a direction of movement from the one end to the other end of the separation plate. In this case, even if the solid portion remains on the separating plate with the pushing plate positioned at one end of the separating plate, the pushing plate separates when moving from one end to the other end of the separating plate. When the solid portion on the plate is in contact with the solid portion, the solid portion is not pushed out from the other end of the separating plate because the solid portion rotates backward with respect to the moving direction.

It may have a scraper which scrapes off the said solid part adhering on the said separating plate. In this case, it is possible to prevent solids from depositing on the separation plate. For this reason, it is possible to well remove the solids adhering to the opening together with the removing member or closing the firing part. Further, the solids scraped off the separating plate by the scraper can be pushed out from one end of the separating plate by the transport mechanism. Thus, the solid on the separating plate can be well transported.

The urine drying apparatus according to the present invention is installed under a toilet bowl having a toilet bowl and a toilet bowl outlet communicating with the toilet bowl and opening downward, and holds urine discharged from the toilet bowl outlet, and It is characterized by comprising a moisture holder to be evaporated.

In this stool drying apparatus, a space under the toilet bowl is used to provide a moisture holder for holding and evaporating the urine. For this reason, the urine discharged from the toilet outlet can be dropped toward the water holding body, and the water holding body can hold the urine. In addition, the water holding body can well evaporate the urine held in the water holding body in the space below the toilet bowl by contact with air.

Therefore, the urine drying apparatus of the present invention can effectively utilize space and can well evaporate the urine with no power supply.

A phosphorus adsorbent may be provided below the toilet bowl, above the water holding body, for adsorbing phosphorus contained in the urine when the urine discharged from the toilet discharge port passes. In this case, since the phosphorus adsorbent adsorbs the phosphorus contained in the urine, the phosphorus contained in the urine can be easily recovered. The recovered phosphorus can be used as fertilizer.

The phosphorus adsorbent may have a bottom plate provided with a discharge port for discharging the urine downward, and a side wall rising from the outer periphery of the bottom plate, and may be housed in a container opened at the top. In this case, a phosphorus adsorbent is accommodated in the container, and urine is retained while passing through the container. For this reason, the urine can be evaporated while passing through the container.

The phosphorus adsorbent can carry decomposing bacteria that degrade urine. In this case, since the urine is degraded by the degrading bacteria, the generation of odor can be reduced.

The water carrier can be divided into a plurality. In this case, a space can be formed between the divided moisture holders. As a result, air flows in the space formed between the water holding members, and evaporation of urine from each water holding member is promoted. In addition, since the water holding body is divided, urine does not immediately reach the water holding body located below. For this reason, urine does not gather only on the water holding body located at the lowermost end, and the water holding bodies can disperse and hold the urine. Therefore, since evaporation of the urine is performed from each water holding body, the evaporation efficiency can be enhanced.

The water holding body may be flat and horizontally spaced, may be vertically spaced with an interval, and may be suspended below the toilet bowl. In this case, since the water holding body can sufficiently hold the urine and air flows between the water holding bodies, contact with the air is easily performed, and evaporation of the urine is promoted.

The water holding body may be in the form of a ring, and the hanging member may be inserted into the central space and held there, and may be hung below the toilet bowl. In this case, since the moisture support is suspended, contact with air is easily performed. In addition, since the air also flows to the central space, the evaporation of urine is promoted.

The water support may be porous or fibrous. In this case, the water holding body can well hold the urine.

The toilet equipment of the present invention is provided with a toilet bowl having a toilet bowl and a toilet bowl outlet communicating with the bowl and opened downward, and the toilet bowl outlet provided with the toilet bowl outlet, and the toilet bowl is discharged from the toilet bowl outlet. The apparatus is characterized by comprising a solid-liquid separation device for separating matter into urine and feces, and the above-mentioned urine drying device provided below the solid-liquid separation device.

In this toilet equipment, a solid-liquid separation device and a urine drying device are disposed using a space below the toilet bowl. For this reason, the urine discharged from the toilet outlet can be dropped directly toward the water holding body, and the water holding body can efficiently hold the urine. In addition, the water holding body holding the urine can evaporate the urine in the space below the toilet bowl.

Therefore, the toilet equipment of the present invention can effectively utilize the space and can evaporate the urine well without power supply.

Also, the solid-liquid separation device of the toilet equipment of the present invention may be the one described above. In this case, separation of stools and transport of stools can be favorably performed.

Embodiments 1 to 3 in which the solid-liquid separation device of the present invention is applied to a toilet facility will be described with reference to the drawings.

Example 1
The toilet equipment of the first embodiment, as shown in FIG. 1, includes a toilet bowl 1, a solid-liquid separation device 10, a fermentation device 20, a urinal drying device 30, and a storage tank 40. The toilet bowl 1 is a non-water flush type, and has a toilet bowl 2 and a toilet bowl outlet 3 communicating with the toilet bowl 2 and opening downward. Further, the toilet seat 4 and the toilet lid 5 are attached to the upper end opening of the toilet bowl 2 so as to rotate. The toilet outlet 3 of the toilet 1 is connected to the opening of the floor member G.

The solid-liquid separator 10 has a separation plate 11, a transport mechanism 13, removal members 16A and 16B, and a scraper 13, as shown in FIGS. On the lower surface of the floor member G, a pair of rail members 7 extend in parallel with the toilet bowl discharge port 3 interposed therebetween. The solid-liquid separation device 10 is engaged with the rail member 7 and slidably suspended and fixed. Therefore, the solid-liquid separation device 10 can be easily removed for installation and maintenance.

The separation plate 11 is flat and disposed horizontally below the toilet bowl discharge port 3. The separation plate 11 arranges a plurality of openings 12 penetrating in a slit shape in parallel at equal intervals. Each of the openings 12 extends in the longitudinal direction from one end 11F of the separating plate 11 to the other end 11B.

Since the separation plate 11 is disposed below the toilet discharge port 3, human excrement is excreted using the toilet bowl 1, and the excrement (solid-liquid mixture) discharged from the toilet discharge port 3 is the upper surface of the separation plate 11. Received by Of the excrement received on the upper surface of the separation plate 11, the urine U, which is a liquid, passes downward from the opening 12, and the stool F, which is a solid, remains on the separation plate 11. Thus, the excrement is separated into the urine U and the stool F by the separation plate 11 of the solid-liquid separator 10.

The transport mechanism 13 has a pushing plate 14 and a drive unit 15. The pushing plate 14 has a strip shape, and can reciprocate between the one end 11 F and the other end 11 B in the longitudinal direction of the separation plate 11. The pushing plate 14 extends in a direction perpendicular to the moving direction, that is, in the left-right direction of the separating plate 11. The left and right ends of the pushing plate 14 extend to the vicinity of the left and right ends 11L and 11R of the separating plate 11. Below the left and right end portions of the pushing plate 14, a pair of first support plates 17 </ b> A are provided along the longitudinal direction of the separating plate 11. The first support plate 17A is provided with a shaft portion 14A at an upper end portion, and pivotally supports the upper portion of the extrusion plate 14. Further, the first support plate 17A has an inclined side 17S, one side of which is formed to descend toward the one end portion 11F of the separation plate 11. The back surface of the pushing plate 14 is in contact with the inclined side 17S. For this reason, the pushing plate 14 is disposed in an inclined state in which the pushing plate 14 descends toward the one end portion 11F of the separating plate 11. Further, the push-out plate 14 axially supported by the first support plate 17A can rotate rearward with respect to the direction of movement from the one end 11F to the other end 11B of the separation plate 11.

The scraper 18 has a flat plate shape elongated in the left-right direction, and is mounted on the upper surface of the separating plate 11. The width of the scraper 18 is slightly shorter than the width of the separating plate 11. Further, the front and rear sides of the scraper 18 are formed in a saw blade shape. Further, the scraper 18 has a slit-like through hole 18A penetrating at a position corresponding to the opening 12 of the separating plate 11 when the scraper 18 is placed on the separating plate 11.

The removing member 16A extends downward from a part of the lower side of the first support plate 17A and is integrally formed. The removing member 16B is formed in a flat plate shape. The removing member 16B is integrally formed with a second support plate 17B at the upper end. Each removal member 16A, 16B forms a through hole through which the connecting member 15L is inserted. The removing members 16A and 16B project through the through holes 18A of the scraper 18 placed on the upper surface of the separating plate 11 and the opening 12 of the separating plate 11 and project below the separating plate 11. The second support member 17B is formed so that the upper end corner 17C located on the side of the one end 11F of the separating plate 11 abuts on the back surface of the pushing plate 14.

The removing member 16A integrally formed on the first support plate 17A and the removing member 16B integrally formed on the second support plate 17B are connected by a rod-like connecting member 15L inserted into the through hole below the separating plate 11 It is done. Each removal member 16A, 16B can reciprocate along each opening 12 in the state inserted in each opening 12 formed in the shape of a slit. The removing members 16A and 16B are connected to and integrated with the push-out plate 14 via the connecting member 15L and the first support plate 17A. Therefore, the pushing plate 14, the removing members 16A and 16B, and the scraper 18 reciprocate together between the one end 11F and the other end 11B of the separating plate 11.

The drive unit 15 includes a pair of first link members 15A and a pair of second link members 15B. One end of each first link member 15A is connected to both ends of the joint shaft 15J. Each first link member 15A can rotate around the joint shaft 15J as the joint shaft 15J rotates. Both ends of the joint shaft 15J are held by a pair of holding plates 15C provided below the floor member G. The pair of holding plates 15C is disposed above the separating plate 11 and has an interval substantially equal to the width of the separating plate 11. The other end of each first link member 15A is connected to one end of each second link member 15B by a joint member 15K. The other end of each second link member 15B is connected to the connecting member 15L.

The joint shaft 15 J fixes the center of the lever member 19. The joint shaft 15J rotates with rotation of the lever member 19 about the joint shaft 15J. The lever member 19 connects one end of the first wire W1 to one end. The first wire W1 passes through the floor member G, and the other end is connected to the lever L1 fixed to the upper surface of the floor member G. The lever L1 is pivotally supported by a fulcrum member L2 fixed to the floor member G, and can be raised and lowered on the floor member G. The lever member 19 connects the other end of the second wire W2 to the other end. The second wire W2 has one end connected to a ratchet portion 22B of a rotation mechanism 22 of the fermentation apparatus 20 described later.

In the drive unit 15 configured as above, when the lever L1 is turned to the upright state, as shown in FIG. 8, the first wire W1 is pulled upward. Then, one end of the lever member 19 is pulled upward. Thus, the joint shaft 15J rotates in one direction. Then, each first link member 15A rotates in one direction about the joint shaft 15J, and each joint member 15K moves in the direction of the separation plate 11. Then, each second link member 15B moves the pushing plate 14 toward the one end 11F of the separating plate 11. Further, the removing members 16A and 16B integrated with the pushing plate 14 and the scraper 18 also move to the one end 11F side of the separating plate 11 along the opening 12. At this time, the stool F on the separating plate 11 is scraped off by the saw blade-shaped front side of the scraper 18, and furthermore, the stool F in which the removal members 16A and 16B adhere to the opening 12 or close the opening 12 The stool F in which the pushing plate 14 remains on the separating plate 11 can be pushed out from one end 11F of the separating plate 11 and dropped into the receiving port 25A of the fermentation apparatus 20 described later.

As described above, since the stool F separated from the urine U and remaining on the separation plate 11 is pushed out from the one end portion 11F of the separation plate 11 by the extrusion plate 14, the water (the urine) in the fermentation chamber C of the fermentation apparatus 20 is reduced. can do. Therefore, in the fermentation chamber C, the stool F can be favorably stirred, and the microorganisms can be maintained in an aerobic state. Therefore, the fermentation process of stool F can be performed favorably. Moreover, the stools F adhering to the opening 12 or closing the opening 12 can be removed well by the removal members 16A and 16B. For this reason, the opening 12 can pass the urine U favorably.

The joint shaft 15J has the first coil spring S1 fitted thereon. The first coil spring S1 applies an elastic force so that the joint shaft 15J rotates in the other direction. For this reason, when the lever L1 is turned to the laid down state, the first wire W1 loses the force of pulling up one end of the lever member 19 upward, and as shown in FIG. 2, the joint by the elastic force of the first coil spring S1. The shaft 15J rotates in the other direction. Then, each first link member 15A pivots in the other direction about the joint shaft 15J, and each joint member 15K moves in a direction away from the separating plate 11. Then, each second link member 15B moves the pushing plate 14 to the other end 11B side of the separation plate 11. Further, the removing members 16A, 16B and the scraper 18 integrally formed with the pushing plate 14 also move to the other end 11B side of the separating plate 11 along the opening 12. Under the present circumstances, even if the stool F remains on the separating plate 11, the pushing plate 14 is in contact with the stool F on the separating plate 11 when moving from the one end 11F to the other end 11B of the separating plate 11. When it contacts, since it rotates backward with respect to the movement direction, the stool F is not pushed out from the other end 11B of the separation plate 11, and can return to the other end 11B. In addition, also when moving the scraper 18 to the other end 11 B side of the separation plate 11, the stool F on the separation plate 11 can be scraped off at the rear edge portion of the saw blade shape. Also, each removal member 16A, 16B removes the stool F adhering to the opening 12 or closing the opening 12 also when moving along the opening 12 toward the other end 11B of the separation plate 11 it can. For this reason, the opening 12 can pass the urine U favorably.

Therefore, the solid-liquid separator 10 can satisfactorily perform separation of the stool F and the urine U (solid-liquid separation) and transport of the stool F (transport of solid content).

As shown in FIGS. 9 to 14, the fermentation apparatus 20 includes a fermentation tank 21 and a rotation mechanism 22 for rotating the fermentation tank 21. The fermenter 21 is rotatably held around an inclined rotation axis. The fermenter 21 includes an outer shell 23, a stirring blade 24, and a baffle 25. The fermentation apparatus 20 is locked to the rail member 7 and slidably suspended and fixed. Therefore, the fermentation apparatus 20 can be easily removed for installation and maintenance.

The outer shell portion 23 is provided with a fermentation chamber C inside, and is formed in a cylindrical shape that is axially symmetrical about the rotation axis. The outer shell portion 23 is formed by connecting four cylindrical members 23A. The baffle plate portion 25 is formed so as to extend inward from one open end of each cylindrical member 23A. The baffle plate 25 is annular, and the opening formed at the center is circular around the rotation axis.

The stirring blade portion 24 has a rectangular shape, and one side thereof is in contact with the inner peripheral surface of the cylindrical member 23A. Further, the stirring blade portion 24 is attached so as to rise from the inner peripheral surface of the cylindrical member 23A toward the center. The four stirring blades 24 are attached to the inner peripheral surface of each cylindrical member 23A, and are disposed on the inner peripheral surface separated by 90 degrees from the central axis of the cylindrical member 23.

The cylindrical members 23 </ b> A are connected by a stirring blade 24 to form an outer shell 23. Under the present circumstances, each cylindrical member 23A is connected so that each stirring blade part 24 may stand | start up toward the center from the inner surface of the outer shell part 23, and it becomes strip shape extended to a rotating shaft direction. Further, the cylindrical members 23A are connected to each other with a gap.

The opening of the baffle plate 25 located on one end side of the outer shell 23 forms a receiving port 25 A of the outer shell 23. Further, the gap provided between the cylindrical members 23A forms a slit-like drainage hole D which is provided along the baffle plate 25 on the side of the baffle plate 25 closer to the receiving port 25A.

An annular baffle plate 26 having a central opening is connected to the cylindrical member 23 </ b> A located on the other end side of the outer shell 23. The central opening of the baffle plate 26 forms a discharge port 26 A of the outer shell 23. A gap is formed between the opening edge of the cylindrical member 23A positioned on the other end side of the outer shell portion 23 and the baffle plate portion 26. This gap also has a slit-like drainage hole D formed along the baffle plate portion 26 on the receiving port 25 A side from the baffle plate portion 26. The drainage hole D provided in the outer shell portion 23 can not be separated by the solid-liquid separation device 10, and can discharge the urine U received in the fermentation chamber C together with the stool F. For this reason, the stool F in the fermentation chamber C can be favorably stirred, and the microorganisms in the fermentation chamber C can be maintained in an aerobic state to perform the fermentation treatment favorably.

Four rectangular connection members 27A are fixed to the baffle plate portion 26. The baffle plate portion 26 and the disk-shaped end surface member 27 are connected by the connection member 27A. One end portion of the rotation shaft portion 22A is connected to the central portion of the end surface member 27.

The rotation mechanism 22 has a rotation shaft portion 22A which forms the inclined rotation shaft of the fermenter 21, a ratchet portion 22B and a lever L1. One end of the second wire W2 is connected to the ratchet portion 22B. Further, the other end of the second wire W 2 is connected to the other end of the lever member 19. Therefore, when the lever L1 is turned to the upright state, the other end of the lever member 19 is lowered, and the second wire W2 is pulled. When the second wire W2 is pulled, the ratchet portion 22B rotates the rotation shaft 22A in one direction by a set angle (for example, 5 degrees).

At one end side of the second wire W2, a second coil spring S2 for inserting the second wire W2 is provided. The second coil spring S2 applies an elastic force in the direction in which the second wire W2 is pulled back. For this reason, when the lever L2 is turned to the laid down state, the other end of the lever member 19 is raised, and the pulling force of the second wire W2 disappears, so the second wire W2 is pulled back. At this time, the ratchet portion 22B does not rotate the rotation shaft 22A, and the state of the fermenter 21 is maintained.

The other end of the rotation shaft 22A is held by the ratchet 22B. The ratchet portion 22 is slidably suspended on the rail member 7 provided on the lower surface of the floor member G so as to hold the rotation shaft portion 22A in an inclined state, and is inclined to the fixed first attachment member 22C. Is attached.

The fermenter 21 fixes one end portion of the inclined rotation shaft portion 22A to the central portion of the end surface member 27. On the other hand, two guide members 29 for guiding the rotation of the fermenter 21 are in contact with the inner peripheral surface of the receiving port 25A. These guide members 29 are slidably suspended on a rail member 7 provided on the lower surface of the floor member G and fixed to a second mounting member 29A fixed.

Thus, the fermenter 21 disposed below the floor member G has the receiving port 25A disposed at the upper end of the outer shell 23 in the rotational axis direction, and is discharged at the lower end in the rotational axis direction. An outlet 26A is arranged. That is, the fermentation chamber C is inclined downward from the inlet 25A to the outlet 26A. Further, one end portion 11F of the separation plate 11 is inserted into the receiving port 25A of the outer shell portion 23.

At the upper end position of the drainage hole D provided in the outer shell portion 23, the insertion tool 28 slidably engaged with the rail member 7 provided on the lower surface of the floor member G and suspended from the fixed suspension member 8 The lower end of the is inserted. The insertion tool 28 is on a flat plate whose lower side is formed in a V shape. When the fermenter 21 is rotated, the drainage hole D is also rotated along the insertion tool 28, so that the stool F closing the drainage hole D is sequentially removed by the insertion tool 28. For this reason, the urine U included in the stool F can be favorably discharged from the drainage hole D.

In the fermentation apparatus 20 configured in this manner, the fermentation chamber C is inclined downward from the inlet 25A to the outlet 26A. For this reason, the stool F received in the fermentation chamber C moves to the outlet 26A side by gravity. Downward movement of the stool F which has moved to the discharge port 26A side is blocked by the baffle portion 25. For this reason, the stool F received in the fermentation chamber C from the receiving port 25A is not immediately discharged from the discharge port 26A, remains in the fermentation chamber C, and the fermentation process is performed during that time.

The stool F whose movement toward the discharge port 26A is blocked by the baffle plate portion 25 is pushed up above the inside of the fermentation chamber C by the stirring wing portion 24 when the fermentation tank 21 is rotated by the rotation mechanism 22. As shown in FIGS. 9 and 14, the stool F pushed up to a certain height falls from the upper surface of the stirring blade 24 to the lower side in the fermentation chamber C. At this time, since the fermentation chamber C is inclined downward, the stool F deposited at a position close to the baffle plate 25 falls to the outlet 26A side of the baffle plate 25. Thus, by rotating the fermenter 21, the stool F in the fermentation chamber C gradually moves to the discharge port 26A side, and is finally discharged from the discharge port 26A. For this reason, in this fermentation apparatus 20, regardless of the amount of stool F in the fermentation chamber C, the stool F received in the fermentation chamber C can be sequentially discharged from the discharge port while being stirred, and the stool F is in the fermentation chamber The variation of the time of residence in C is small, and the stool F can be subjected to fermentation treatment continuously.

In addition, stools received from the inlet 25A to the fermentation chamber C by changing the inclination angle of the rotary shaft of the fermentation tank 21 or changing the number and shape of the stirring blade 24 and the baffle plate 25. It is possible to adjust the number of rotations of the fermenter 21 until the F is discharged from the discharge port 26A. That is, the time for which the stool F stays in the fermentation chamber C can be adjusted. For this reason, during a predetermined period (for example, for one month), the stool F can be retained in the fermentation chamber C, and the stool F can be sufficiently fermented. In addition, since the stool F is agitated by the fall of the stool F being repeated in the fermentation chamber C by rotating the fermenter 21, the microorganisms contained in the stool F are maintained in an aerobic state, and the stool F is It can be fermented well.

In addition, in this fermentation apparatus 20, only the stool F is received in the fermentation chamber C for fermentation treatment without storing the fungus bed, and therefore, a volume for storing the fungus bed is not required. In addition, since the stool F in the fermentation chamber C is automatically discharged from the discharge port 26A into the storage tank 40 after the fermentation treatment, it does not require an operation of taking out the stool F after the fermentation treatment from the fermentation chamber C.

Therefore, the toilet equipment of the first embodiment can be downsized, the excrement can be favorably treated, and maintenance can be reduced.

Further, since the fermentation chamber C is inclined downward, the urine U received in the fermentation chamber C gathers on the receiving port 25A side of the baffle plate portion 25. For this reason, the urine of the urine can be favorably drained by the slit-like drainage hole D provided through the portion. In this way, since the water (pimples U) in the fermentation chamber C can be further reduced, the stool F can be well stirred, and the aerobic state suitable for the treatment with the microorganism can be well maintained. Furthermore, it can be maintained in a water environment in which microorganisms can more easily propagate. Therefore, the fermentation treatment of stools F can be performed better.

In addition, by manually operating the lever L1, the fermentation apparatus 20 can be rotated without power. Moreover, if the user operates the lever L1 after using the toilet bowl 1, the fermenter 21 can be rotated by a set angle (for example, 5 degrees) each time. Thereby, according to the usage frequency of the toilet bowl 1, the fermenter 21 can be rotated. Further, as described above, the stool F in the fermentation chamber C moves from the receiving port 25A to the discharge port 26A by the rotation of the fermenter 21 and is discharged from the discharge port 26A. Further, since the stool F can be uniformly mixed and stirred, and an appropriate amount of the stool F can be retained in the fermentation chamber C, the fermentation treatment can be favorably performed. In addition, the internal space in the fermentation chamber C can be effectively utilized.

As shown in FIG. 1, FIG. 15, and FIG. 16, the urine drying device 30 has a water holding body 31 suspended below the separation plate 11 of the solid-liquid separation device 10 and the fermentation device 20. Thus, the urine drying device 30 is disposed utilizing the space under the toilet bowl 1 (below the solid-liquid separation device 10 and the fermentation device 20).

The water holding body 31 is an annular shape formed of a non-woven fabric. For this reason, it is possible to keep the urine F well and to evaporate it. The rope 31A is inserted into the central space portion of the water holding body 31, and a plurality of water holding bodies 31 are held. A weight 31B is connected to the lowermost end of the rope 31A in order to prevent the moisture holding body 31 from falling off and to vertically suspend the rope 31A. The rope 31A is connected to a hanging rope 31C stretched between a solid-liquid separation device 10 and a hanging member 32 protruding to the side of the fermentation device 20.

The urine U separated from the stool F by the solid-liquid separation device 10 drops directly from the opening 12 of the separation plate 11 toward the water holding body 31 and is held by the water holding body 31. Since the water holding body 31 is suspended, contact with air is facilitated, and the urine U held by the water holding body 31 can be well evaporated in the space below the toilet bowl 1.

Therefore, the urine drying apparatus 30 of the first embodiment can effectively utilize the space and can well evaporate the urine with no power supply.

In particular, since the water holding body 31 is divided into a plurality, a space can be formed between the water holding bodies 31. Thereby, air flows in the space formed between the water holding members 31 and evaporation of the urine U from the water holding members 31 is promoted. In addition, since the air also flows in the central space portion of each water holding body 31, evaporation of the urine U is further promoted.

Moreover, since the water holding body 31 is divided, the urine does not immediately penetrate into the water holding body 31 located below. For this reason, the urine does not gather only on the water holding body 31 located at the lowermost end, and the water holding bodies 31 can disperse and hold the urine. Therefore, the evaporation of the urine is carried out from each water holding body 31, and the evaporation efficiency can be enhanced.

In addition, the water holding body 31 suspended downward is suspended so as to contact the bottom surface 42 of the storage space for storing the urine drying device 30. For this reason, the other water holding body 31 can absorb and evaporate the urine U which has flowed to the bottom surface 42 without being kept in the water holding body 31.

The storage tank 40 is provided below the discharge port 26A of the fermentation apparatus 20, as shown in FIG. The processed stool which is the processed waste fermented in the fermentation chamber C discharged from the discharge port 26A is stored. The storage tank 40 is partitioned by the partition wall 41 from the storage space of the urinal drying device 30. That is, the partition wall 41 is erected below the discharge port 26A. Thereby, the urine U that has flowed out to the bottom surface 42 of the storage space without evaporation from the water holding body 31 of the urine drying device 30 is prevented from flowing into the storage tank 40. For this reason, the treated stool stored in the storage tank 40 does not get wet, and the microorganisms contained therein can be maintained in an aerobic state, so that the fermentation treatment is promoted even in the state stored in the storage tank 40 can do.

An exhaust pipe 50 for discharging an odor is connected to the floor member G above the storage tank 40. A fan (not shown) is connected to the exhaust pipe 50 and forced exhaust can be performed. Therefore, the solid-liquid separation device 10, the fermentation device 20, and the urine drying device 30 can be stored, the odor of the space forming the storage tank 40 can be discharged, and the evaporation of the urine U in the urine drying device 30 is promoted. be able to.

The upper side wall of the storage tank 40 is used to carry out the processed stool when the processed stool accumulates in the storage tank 40, or to check the solid-liquid separation device 10, the fermentation device 20, and the urine drying device 30. An inspection port 42 is provided. A lid member 42A is attached to the inspection opening 42. Further, the lid member 42A is provided with an inlet 43 for mixing the processed stool stored in the storage tank 40 with ash.

The toilet equipment of Example 1 configured in this way is used as follows, and excrement is treated.

When the user of the toilet bowl 1 performs the stool F, the user then turns the lever L1 to the upright state. Then, the stool F is separated from the urine U by the solid-liquid separator 10 and the stool F remaining on the separation plate 11 is pushed out from the one end 11 F of the separation plate 11 by the extrusion plate 14. It falls into C. When the lever L1 pivots to the upright state, the fermenter 21 of the fermenter 20 rotates by a set angle (for example, 5 degrees). Then, the stool F staying in the fermentation chamber C is moved upward by the stirring blade 24. At this time, a part of the stool F falls from the upper surface of the agitating blade portion 24 downward in the fermentation chamber C. Also, the stool F deposited at a position close to the baffle plate portion 25 falls to the outlet 26A side of the baffle plate portion 25. In this manner, the stool F gradually moves toward the discharge port 26A.

When the stool F pushed out from one end 11F of the separation plate 11 is received in the fermentation chamber C, the rotation of the fermenter 21 is completed. On the other hand, the urine U drops downward from the opening 12 of the separation plate 11 of the solid-liquid separator 10 and is held by the water holding body 31. Thereafter, the urine U held by the water holding body 31 is evaporated.

When the user turns the lever L1 to the laid down state, the push-out plate 14 of the solid-liquid separation device 10 moves to the other end 11B side of the separation plate 11. The pushing plate 14 reciprocates between the one end 11 F and the other end 11 B of the separation plate 11, and the removing members 16 A and 16 B and the scraper 18 also reciprocate along the opening 12. The stool F adhering to or closing the opening 12 is removed. For this reason, urinals U used after the toilet bowl 1 is used and excreted can pass through the opening 12 of the separation plate 11 well. That is, the solid-liquid separator 10 can separate the stool F and the urine U well. Thus, movement of the pushing plate 14 of the solid-liquid separator 10 and rotation of the fermenter 21 can be performed by operating one lever L1.

By repeating the use of the toilet bowl 1, the stool F can be received from the inlet 25A into the fermentation chamber C of the fermentation apparatus 20, and the processed stool can be discharged from the discharge port 26A. That is, the fermentation apparatus 20 can continuously perform the reception, the fermentation process, and the discharge of the stool F. In addition, by staying in the fermentation chamber C for a predetermined period (for example, for one month), the stool F can be sufficiently fermented. As described above, in this toilet facility, the waste material can be treated with no power supply when the user operates the lever L2.

Example 2
In the toilet apparatus of the second embodiment, as shown in FIGS. 17 and 18, the drive unit 115 of the transport mechanism 113 of the solid-liquid separator 110 differs from the configuration of the first embodiment. The other configuration is the same as that of the first embodiment, and the same reference numerals are given to the same configuration as the first embodiment and the detailed description will be omitted.

The joint shaft 15J of the drive unit 115 fixes the central portion of the lever member 119. The joint shaft 15J rotates with rotation of the lever member 119 about the joint shaft 15J. The lever member 119 is formed in a rectangular shape whose both sides are arc-shaped. The lever member 119 connects one end portion of the first wire W1 to the lower portion 119A of one of the arc-shaped end sides. Further, the lever member 119 connects one end portion of the third wire W3 to the lower portion 119B of the other arc-shaped end side. The lever member 119 has a groove formed so that the first wire W1 or the third wire W3 is along each of the arc-shaped both end sides.

A lever L11 is mounted on the floor member G. The lever L11 has a disk-shaped end L12 and a lever L13 extending from the end 11A. The lever L11 is pivotally supported by the fulcrum member L20 at the center of the end 11A. The fulcrum member L20 is fixed to the floor member G. For this reason, the lever portion L13 of the lever L11 is undulated on the floor member G.

The first wire W1 passes through the floor member G, and the other end is drawn upward from the front side (right side in FIG. 17) of the end L12 of the lever L11. The other end of the first wire W1 is fixed to the outer peripheral edge of the end L12 of the lever L11. The third wire W3 is inserted through the floor member G, and the other end is drawn upward from the rear side (left side in FIG. 17) of the end L12 of the lever L11. The other end of the third wire W3 is fixed to the outer peripheral edge of the end L12 of the lever L11.

The joint shaft 15J of the drive unit 115 fixes the fan-shaped rotating member 120. The other end of the second wire member W2 is connected to the lower end of the arc portion of the rotating member 120. The rotary member 120 forms a groove so that the second wire W2 follows the arc. The rotation member 120 rotates so that the arc portion draws a substantially semicircle in accordance with the rotation of the joint shaft 15J. The second wire W2 has one end connected to the ratchet portion 22B of the rotation mechanism 22 of the fermentation apparatus 20.

When the drive portion 115 configured in this manner turns the lever portion L13 of the lever L11 in the upright state, as shown in FIG. 18, the first wire W1 is pulled upward. Then, one end of the lever member 119 is pulled up. Thereby, the joint axis J rotates in one direction. Then, each first link member 15A rotates in one direction about the joint shaft 15J, and each joint member 15K moves in the direction of the separation plate 11. Then, each second link member 15B moves the pushing plate 14 toward the one end 11F of the separating plate 11. Further, the removing members 16A and 16B integrated with the pushing plate 14 and the scraper 18 also move to the one end 11F side of the separating plate 11 along the opening 12. At this time, the stool F on the separating plate 11 is scraped off by the saw blade-shaped front side of the scraper 18, and furthermore, the stool F in which the removal members 16A and 16B adhere to the opening 12 or close the opening 12 The stool F with the extrusion plate 14 remaining on the separation plate 11 can be pushed out from one end 11 F of the separation plate 11 and dropped into the receiving port 25 A of the fermentation apparatus 20 while removing

As described above, since the stool F separated from the urine U and remaining on the separation plate 11 is pushed out from the one end portion 11F of the separation plate 11 by the extrusion plate 14, the water (the urine) in the fermentation chamber C of the fermentation apparatus 20 is reduced. can do. Therefore, in the fermentation chamber C, the stool F can be favorably stirred, and the microorganisms can be maintained in an aerobic state. Therefore, the fermentation process of stool F can be performed favorably. Moreover, the stools F adhering to the opening 12 or closing the opening 12 can be removed well by the removal members 16A and 16B. For this reason, the opening 12 can pass the urine U favorably.

When the lever portion L13 of the lever L11 is turned to the laid down state, as shown in FIG. 17, the third wire W3 is pulled upward. Then, the other end of the lever member 119 is pulled up. Thereby, the joint axis J rotates in the other direction. Then, each first link member 15A pivots in the other direction about the joint shaft 15J, and each joint member 15K moves in a direction away from the separating plate 11. Then, each second link member 15B moves the pushing plate 14 to the other end 11B side of the separation plate 11. Further, the removing members 16A, 16B and the scraper 18 integrally formed with the pushing plate 14 also move to the other end 11B side of the separating plate 11 along the opening 12. Under the present circumstances, even if the stool F remains on the separating plate 11, the pushing plate 14 is in contact with the stool F on the separating plate 11 when moving from the one end 11F to the other end 11B of the separating plate 11. When it contacts, since it rotates backward with respect to the movement direction, the stool F is not pushed out from the other end 11B of the separation plate 11, and can return to the other end 11B. In addition, also when moving the scraper 18 to the other end 11 B side of the separation plate 11, the stool F on the separation plate 11 can be scraped off at the rear edge portion of the saw blade shape. Also, each removal member 16A, 16B removes the stool F adhering to the opening 12 or closing the opening 12 also when moving along the opening 12 toward the other end 11B of the separation plate 11 it can. For this reason, the opening 12 can pass the urine U favorably.

Therefore, the solid-liquid separator 110 can perform separation of the stool F and the urine U (solid-liquid separation) and transport of the stool F (transport of solid content) well.

In addition, when the lever portion L13 of the lever L11 is turned to the upright state, the rotating member 120 rotates in one direction, and the second wire W2 is pulled downward. When the second wire W2 is pulled, the ratchet portion 22B of the rotation mechanism 22 rotates the rotation shaft 22A in one direction by a set angle (for example, 5 degrees). When the lever portion L13 of the lever L11 is turned to the laid-down state, the rotating member 120 rotates in the other direction, and the pulling force of the second wire W2 disappears, so the second wire W2 is pulled back. At this time, the ratchet portion 22B does not rotate the rotation shaft 22A, and the state of the fermenter 21 is maintained. Thus, the fermenter 21 of the fermentation apparatus 20 can be rotated by the rotation mechanism 22 by raising and lowering the lever portion L13 of the lever L11.

Example 3
The toilet equipment of the third embodiment, as shown in FIG. 17, includes a toilet bowl 1, a solid-liquid separation device 60, a urinal drying device 80, and a storage tank 90. About the same composition as Example 1, the same numerals are attached and detailed explanation is omitted.

The solid-liquid separator 60 has a separation plate 61, a transport mechanism 63, removing members 66A and 66B, and a scraper 68, as shown in FIGS. On the lower surface of the floor member G, a pair of rail members 57 is provided extending in parallel with the toilet bowl discharge port 3 interposed therebetween. The solid-liquid separation device 60 is engaged with the rail member 57 and is slidably suspended and fixed. Therefore, the solid-liquid separation device 60 can be easily removed for installation and maintenance.

The separation plate 61 is flat and disposed horizontally below the toilet bowl discharge port 3. The separation plate 61 arranges a plurality of openings 62 penetrating in a slit shape in parallel. Each of the openings 62 extends in the longitudinal direction from one end 61F of the separation plate 61 to the other end 61B. The separation plate 61 includes left and right side plates 61A extending upward from the left and right end portions 61L and 61R, and left and right upper plates 61B extending outward from upper ends of the left and right side plates 61A. The left and right upper plates 61B fix the locking plates 61D at both end portions in the vertical direction via the spacers 61C. When the left and right end portions of the locking plate 61D are locked to the rail members 57, the solid-liquid separation device 60 is suspended and fixed.

Since the separation plate 61 is disposed below the toilet discharge port 3, human excrement is excreted using the toilet bowl 1, and the excrement (solid-liquid mixture) discharged from the toilet discharge port 3 is the upper surface of the separation plate 61. Received by Of the excrement received on the upper surface of the separation plate 61, the urine U, which is a liquid, passes downward from the opening 62, and the stool F, which is a solid, remains on the separation plate 61. Thus, the excrement is separated into the urine U and the stool F by the separation plate 61 of the solid-liquid separation device 60.

The transport mechanism 63 has a pushing plate 64 and a drive unit 65. The pushing plate 64 has a strip shape, and can reciprocate between one end 61 F and the other end 61 B in the longitudinal direction of the separating plate 61. The pushing plate 64 extends in a direction perpendicular to the moving direction, that is, in the left-right direction of the separating plate 61. The left and right ends of the pushing plate 64 extend to the vicinity of the left and right ends 61 L and 61 R of the separating plate 61. Below the left and right end portions of the pushing plate 64, a pair of first support plates 67 </ b> A are provided along the vertical direction of the separating plate 61. The first support plate 67A is provided with a shaft portion 64A at an upper end portion, and pivotally supports the upper portion of the pushing plate 64. Further, the first support plate 67A has an inclined side 67S, one side of which is formed to descend toward the one end portion 61F of the separation plate 61. The back surface of the pushing plate 64 is in contact with the inclined piece 67S. For this reason, the pushing plate 64 is disposed in an inclined state in which it descends toward the one end portion 61F side of the separation plate 61. Further, the pushing plate 64 pivotally supported by the first support plate 67A can be rotated rearward with respect to the direction of movement from the one end portion 61F of the separation plate 61 to the other end portion 61B.

The scraper 68 is a flat plate elongated in the left-right direction, and is mounted on the upper surface of the separating plate 61. The width of the scraper 68 is slightly shorter than the width of the separation plate 61. Further, the front and rear sides of the scraper 68 are formed in a saw blade shape. Further, the scraper 68 has a slit-like through hole 68A penetrating at a position corresponding to the opening 62 of the separating plate 61 when the scraper 68 is mounted on the separating plate 61.

The removing member 66A extends downward from a part of the lower side of the first support plate 67A and is integrally formed. The removing members 66B and 66C are formed in a flat plate shape. Each removal member 66A, 66B, 66C has formed the through-hole which 15 L of connection members penetrate. Further, the pair of removal members 66C form two bolt holes for connecting to both ends of a connection member 65D of the drive unit 65 described later. The removing members 66A, 66B, and 66C protrude below the separating plate 11 through the through holes 68A of the scraper 68 placed on the upper surface of the separating plate 21 and the opening 12 of the separating plate 21. The removing members 66B and 66C integrally form a second support plate 67B at the upper end. The second support plate 67B is formed such that the upper end corner portion 67C located on the side of the one end portion 61F of the separating plate 61 abuts on the back surface of the pushing plate 64.

The removing members 66A integrally formed on the first support plate 67A and the removing members 66B and 66C integrally formed on the second support plate 67B are formed by rod-like connecting members 15L inserted into the through holes below the separating plate 61. It is connected. The removal members 66A, 66B, and 66C can reciprocate along the openings 62 while being inserted into the openings 62 formed in a slit shape. Further, the removing members 66A, 66B, 66C are connected to and integrated with the push-out plate 64 via the connecting member 15L and the first support plate 67A. Therefore, the pushing plate 64, the removing members 66A, 66B, 66C, and the scraper 68 reciprocate together between the one end 61F and the other end 61B of the separating plate 61.

The driving unit 65 includes a cylindrical outer casing 65A provided at both ends, a rod-like rod member 65B slidably housed in each outer casing 65A, and entering and exiting from the tip of the outer casing 65A, and each rod member 65B. A push-pull cable having an inner cable connecting the rear end portions is employed. The tip of one rod member 65B of the push-pull cable is connected to a connecting member 65D connected to the removing member 66C. Further, the tip of the other rod member 65B of this push-pull cable is connected to the lever L3. The lever L3 can reciprocate along the vertically extending opening 69A provided in the operation box 69 fixed to the wall surface of the toilet room in which the toilet 1 is installed.

When the drive unit 65 configured in this manner moves the lever L3 to the upper end of the opening 69A of the operation box 69, as shown in FIG. 21 and FIG. 22, one rod member 65B of the push-pull cable Most part is drawn into the outer casing 65A. As a result, the pushing plate 64, the removing members 66A, 66B, 66C, and the scraper 68 move to the one end portion 61F side of the separating plate 61. At this time, while the stool F on the separating plate 61 is scraped off by the saw blade-like front side of the scraper 68, each of the removing members 66A, 66B, 66C adheres to the opening 62 or closes the opening 62. While removing the stools F, the stools F in which the pushing plate 64 remains on the separating plate 61 can be pushed out from one end 61 F of the separating plate 61 and dropped into the storage tank 90.

As described above, since the stool F separated from the urine U and remaining on the separating plate 61 is pushed out from the one end portion 61F of the separating plate 61 by the pushing plate 64, the water (purple) in the storage tank 90 can be reduced. .

When the lever L3 is moved to the lower end of the opening 69A of the operation box 69, as shown in FIGS. 17 to 19, one rod member 65B of the push-pull cable projects from the tip of the outer casing 65A. As a result, the pushing plate 64, the removing members 66A, 66B, 66C, and the scraper 68 move to the other end 61B side of the separating plate 61. At this time, even if the stool F remains on the separating plate 61, the pushing plate 64 moves to the side of the separating plate 61 when moving from the one end 61F to the other end 61B. When it abuts, the stool F is not pushed out from the other end 61 B of the separation plate 61 and can return to the other end 61 B because it rotates backward with respect to the movement direction. In addition, also when moving the scraper 68 to the other end portion 61 B side of the separation plate 61, the stool F on the separation plate 61 can be scraped off at the rear edge portion of the saw blade shape. Further, each removal member 66A, 66B, 66C removes the stool F adhering to the opening 62 or closing the opening 62 also when moving along the opening 62 toward the other end 61B of the separation plate 61. be able to. For this reason, the opening 12 can pass the urine U favorably.

Therefore, the solid-liquid separator 60 can satisfactorily perform separation of the stool F and the urine U (solid-liquid separation) and transport of the stool F (transport of solid content).

As shown in FIG. 17, the feces drying device 80 includes a water holding body 81 and a phosphorus adsorbent 82. The phosphorus adsorbent 82 is accommodated in a container 83 provided below the toilet bowl 1 and below the solid-liquid separation device 60 and above the water holding member 81. The container 83 has a bottom plate portion 84 provided with the discharge port 84A, and a side wall portion 85 rising from the outer peripheral portion of the bottom plate portion 84, and the upper side is open. The phosphorus adsorbing body 82 is formed of a waste medium carrying charcoal, a degrading bacteria that decomposes urine, a sphere 82A having a high adsorptivity of phosphorus such as Akadoma soil, and a scaly molded body 82B covering the sphere 82A.

A plurality of the water holding bodies 81 are suspended below the discharge port 84A of the container 83 at intervals in the vertical direction in the state of being spread in the horizontal direction and being spaced apart in the vertical direction. For this reason, air flows above and below the water holding body 81.

The urine drying apparatus 80 configured in this way is discharged from the toilet discharge port 3, and the urine U separated from the stool F by the solid-liquid separation device 60 is retained as moisture through the container 83 in which the phosphorus adsorbent 82 is housed. It can be held by the body 81. In addition, the water holding body 81 can sufficiently hold the urine U, and is easily in contact with the air, and the urine U held in the water holding body 81 evaporates well in the space below the toilet bowl 1 be able to.

Therefore, the urine drying apparatus 80 of Example 3 can also effectively utilize the space and can well evaporate the urine with no power supply.

Moreover, since the urine absorption device 80 adsorbs the phosphorus contained in the urine U, the phosphorus adsorbent 82 can easily recover the phosphorus contained in the urine U. The recovered phosphorus can be used as fertilizer. Further, since the phosphorus adsorbent 82 is housed in the container 83, the urine can be evaporated while passing through while the urine is staying in the container 83.

In the side wall of the storage space below the toilet bowl 1 in which the urine drying device 80 is stored, an opening 86 for replacing the phosphorus adsorbent 82 and the water holding body 81 is provided. A lid 86A is attached to the opening 86.

The storage tank 90 stores the stool F pushed out from one end 61 F of the solid-liquid separation device 60. The storage tank 90 is divided by the partition wall 41 from the storage space in which the urine drying device 80 is stored. For this reason, the urine U that has flowed out to the bottom surface 42 of the storage space without evaporation from the water holding body 81 of the urine drying device 80 is prevented from flowing into the storage tank 90. Therefore, with regard to the stool F stored in the storage tank 90, the fermentation treatment is gently performed by the microorganisms contained therein.

The toilet equipment of Example 3 configured in this way is used as follows, and excrement is treated.

When the user of the toilet bowl 1 performs the stool F, the user subsequently moves the lever L3 to the upper end of the opening 69A of the operation box 69. Then, the stool F separated from the urine U by the solid-liquid separator 60 and remaining on the separation plate 61 is pushed out of the one end portion 61 F of the separation plate 61 by the pushing plate 64 and falls into the storage tank 90. The stools F dropped into the storage tank 90 are subjected to a gentle fermentation process.

On the other hand, the urine U drops downward from the opening 62 of the separation plate 61 of the solid-liquid separation device 60 and is held by the water holding body 81 via the container 83 in which the phosphorus adsorbent 82 is stored. For this reason, the urine is adsorbed with phosphorus by the phosphorus adsorbent 82 and evaporated in the water holding body 81.

When the user moves the lever L3 to the lower end portion of the opening 69A of the operation box 69, the push plate 64 of the solid-liquid separation device 60 moves to the other end 61B side of the separation plate 61. Thus, the pushing plate 64 reciprocates between the one end 61F and the other end 61B of the separating plate 61, and the removing members 66A, 66B, 66C, and the scraper 68 also reciprocate. The stool F adhering to or closing the opening 62 is removed. For this reason, urinals U used after the toilet bowl 1 is used and excreted can pass the opening 62 of the separation plate 61 well. That is, the solid-liquid separation device 60 can separate the stool F and the urine U favorably. Thus, waste can be treated without power by operating the lever L3.
