Description

  The present invention relates to a solid-liquid separator.

  Patent Document 1 discloses a conventional solid-liquid separation device. This solid-liquid separator is configured by arranging a roller conveyor in which a plurality of rollers are continuously arranged in an inclined state. This solid-liquid separator is provided below the toilet outlet, and separates human excrement into stool that is solid and urine that is liquid. That is, when the excrement falls on the roller conveyor from the toilet outlet, the stool descends on the roller conveyor. On the other hand, urine falls downward from the gap between the rollers of the roller conveyor. Thus, this solid-liquid separator can separate human excrement into stool and urine, and can transport stool.

JP 2005-143718 A

  However, in the conventional solid-liquid separator, there is a risk that stool fills the space between the rollers of the roller conveyor. If the space between the rollers of the roller conveyor is filled with stool, the urine will not easily fall downward from the gap between the rollers, resulting in insufficient solid-liquid separation or smooth rotation of the rollers. The stool may not be transported well.

  This invention is made | formed in view of the said conventional situation, Comprising: It is set as the problem which should be solved to provide the solid-liquid separation apparatus which can perform solid-liquid separation and solid content conveyance favorably.

The solid-liquid separation device of the present invention is a solid-liquid separation device that separates a solid-liquid mixture of human excrement into a solid component and a liquid component,
A separation plate disposed substantially horizontally in a flat plate shape provided with an opening for receiving the solid-liquid mixture on the upper surface and passing the liquid component downward;
A transport mechanism for extruding the liquid component remaining on the separation plate and the solid component separated from one end of the separation plate;
It has the removal member which removes the said solid content adhering to the said opening part, or closing this opening part, It is characterized by the above-mentioned.

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

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

  The opening provided in the separation plate is formed in a slit shape extending from the one end to the other end of the separation plate, and the removal member is inserted into the opening in the opening. Can reciprocate along. In this case, by moving the removing member back and forth, the solid component adhering to the opening or closing the opening can be removed favorably, and the opening can pass the liquid satisfactorily.

  The transport mechanism has a strip-shaped extrusion plate that reciprocates between the one end portion and the other end portion of the separation plate, and extends in a direction perpendicular to the movement direction. The removal member can be connected and integrated. In this case, the extrusion plate and the removal member are reciprocated between the one end and the other end of the separation plate together to push out the solid content on the separation plate from the one end and adhere to or open the opening. The solid component that closes the part can be removed well.

  The extrusion plate may be pivotally supported so as to rotate backward with respect to the direction of movement from the one end portion to the other end portion of the separation plate. In this case, even if the solid component remains on the separation plate in a state where the extrusion plate is positioned at one end portion of the separation plate, the extrusion plate is separated when moving from one end portion to the other end portion of the separation plate. When it comes into contact with the solid content on the plate, it rotates backward with respect to the moving direction, so that the solid content is not pushed out from the other end of the separation plate.

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

<Example 1>
The toilet facility of Example 1 is provided with the toilet bowl 1, the solid-liquid separator 10, the fermentation apparatus 20, the urine drying apparatus 30, and the storage tank 40, as shown in FIG. The toilet bowl 1 is a non-flush type and has a toilet bowl 2 and a toilet outlet 3 that communicates with the toilet bowl 2 and opens downward. Moreover, the toilet seat 4 and the toilet lid 5 are attached to the upper-end opening part of the toilet bowl 2 so that rotation. The toilet outlet 3 of the toilet 1 is connected to the opening of the floor member G.

  As shown in FIGS. 2 to 8, the solid-liquid separation device 10 includes a separation plate 11, a transport mechanism 13, removal members 16 </ b> A and 16 </ b> B, and a scraper 13. On the lower surface of the floor member G, a pair of rail members 7 are provided extending in parallel with the toilet outlet 3 interposed therebetween. The solid-liquid separation device 10 is fixed to the rail member 7 so as to be slidably suspended. For this reason, the solid-liquid separator 10 can be easily removed for installation and maintenance.

  The separation plate 11 has a flat plate shape and is disposed in a horizontal state below the toilet outlet 3. The separation plate 11 has a plurality of openings 12 penetrating in a slit shape arranged in parallel at equal intervals. Each of these openings 12 extends in the vertical direction from one end 11F of the separation plate 11 to the other end 11B.

  Since the separation plate 11 is arranged below the toilet discharge port 3, human excretion using the toilet 1, and excrement (solid-liquid mixture) discharged from the toilet discharge port 3 is the upper surface of the separation plate 11. Can be received. Of the excrement received on the upper surface of the separation plate 11, the urine U that is a liquid component passes through the opening 12 downward, and the stool F that is a solid component 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 separation device 10.

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

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

  The removal member 16A extends downward from a part of the lower side of the first support plate 17A and is integrally formed. The removal member 16B is formed in a flat plate shape. The removal 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 removal members 16 </ b> A and 16 </ b> B are inserted through the through-hole 18 </ b> A of the scraper 18 placed on the upper surface of the separation plate 11 and the opening 12 of the separation plate 11 and protrude below the separation plate 11. The second support member 17 </ b> B is formed so that the upper end corner portion 17 </ b> C located on the one end portion 11 </ b> F side of the separation plate 11 contacts the back surface of the extrusion plate 14.

  The removal member 16A formed integrally with the first support plate 17A and the removal member 16B formed integrally with the second support plate 17B are connected by a rod-like connection member 15L inserted through the through hole below the separation plate 11. Has been. Each removal member 16A, 16B can reciprocate along each opening 12 in a state of being inserted through each opening 12 formed in a slit shape. Moreover, each removal member 16A, 16B is connected and integrated with the extrusion plate 14 via the connection member 15L and the first support plate 17A. For this reason, the extrusion plate 14, each removal member 16A, 16B, and the scraper 18 reciprocate between the one end portion 11F and the other end portion 11B of the separation plate 11 together.

  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 about the joint shaft 15J while the joint shaft 15J rotates. Both end portions 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 15 </ b> C are disposed above the separation plate 11 and have substantially the same interval as the lateral width of the separation 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 a connecting member 15L.

  The joint shaft 15J fixes the center portion of the lever member 19. The joint shaft 15J rotates as the lever member 19 rotates around the joint shaft 15J. The lever member 19 connects one end of the first wire W1 to one end. The first wire W1 is inserted through the floor member G, and the other end is connected to a 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 2nd wire W2 has connected one end part to ratchet part 22B of rotation mechanism 22 of fermentation device 20 mentioned below.

  When the drive unit 15 configured as described above rotates the lever L1 to the upright state, the first wire W1 is pulled upward as shown in FIG. Then, one end portion of the lever member 19 is pulled upward. As a result, the joint shaft 15J rotates in one direction. Then, each 1st link member 15A rotates to one direction centering on the joint axis | shaft 15J, and each joint member 15K moves to the separation plate 11 direction. Then, each 2nd link member 15B moves the extrusion plate 14 to the one end part 11F side of the separation plate 11. FIG. Further, the removal members 16A and 16B and the scraper 18 integrated with the extrusion plate 14 also move toward the one end portion 11F side of the separation plate 11 along the opening portion 12. At this time, while removing the stool F on the separation plate 11 at the saw blade-shaped front side portion of the scraper 18, the stool F in which the removal members 16 </ b> A and 16 </ b> B adhere to the opening 12 or close the opening 12. While removing the stool, the stool F remaining on the separation plate 11 by the extrusion plate 14 can be pushed out from one end portion 11F of the separation plate 11 and dropped to the receiving port 25A of the fermentation apparatus 20 described later.

  Thus, 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, moisture (urine) in the fermentation chamber C of the fermentation apparatus 20 is reduced. can do. For this reason, in the fermentation chamber C, the stool F can be stirred well and the microorganisms can be maintained in an aerobic state. Therefore, the fermentation process of stool F can be performed satisfactorily. Moreover, the stool F adhering to the opening part 12 or closing the opening part 12 can be favorably removed by the removing members 16A and 16B. For this reason, the opening part 12 can pass the urine U satisfactorily.

  The joint shaft 15J is fitted around the first coil spring S1. 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 lying down state, the first wire W1 has no force to pull up one end of the lever member 19, and the joint of the first coil spring S1 due to the elastic force of the first coil spring S1, as shown in FIG. The shaft 15J rotates in the other direction. Then, each first link member 15A rotates in the other direction around the joint shaft 15J, and each joint member 15K moves in a direction away from the separation plate 11. Then, each 2nd link member 15B moves the extrusion board 14 to the other end part 11B side of the separation plate 11. FIG. Further, the removal members 16 </ b> A and 16 </ b> B formed integrally with the extrusion plate 14 and the scraper 18 also move along the opening 12 toward the other end 11 </ b> B of the separation plate 11. At this time, even if the stool F remains on the separation plate 11, the pusher plate 14 contacts the stool F on the separation plate 11 when moving from the one end 11 F to the other end 11 B of the separation plate 11. When it comes into contact, the stool F is rotated backward with respect to the moving direction, so that the stool F can be returned to the other end portion 11B without being pushed out from the other end portion 11B of the separation plate 11. Further, when the scraper 18 moves to the other end portion 11B side of the separation plate 11, the stool F on the separation plate 11 can be scraped off at the saw blade-like rear side portion. Further, each removal member 16A, 16B can remove the stool F adhering to the opening 12 or closing the opening 12 when moving to the other end 11B side of the separation plate 11 along the opening 12. it can. For this reason, the opening part 12 can pass the urine U satisfactorily.

  Therefore, the solid-liquid separation device 10 can satisfactorily separate the stool F and the urine U (separation of the solid and liquid) and transport the stool F (convey solid matter).

  As shown in FIGS. 9 to 14, the fermenter 20 includes a fermenter 21 and a rotating mechanism 22 that rotates the fermenter 21. The fermenter 21 is held so as to be rotatable about an inclined rotation axis. The fermenter 21 has an outer shell part 23, a stirring blade part 24, and a baffle plate part 25. The fermentation apparatus 20 is suspended and fixed to the rail member 7 so as to be slidable. For this reason, the fermentation apparatus 20 can be easily removed for installation and maintenance.

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

  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. Four stirring blades 24 are attached to the inner peripheral surface of each cylindrical member 23 </ b> A, and are disposed on the inner peripheral surface that is 90 degrees apart from the central axis of the cylindrical member 23.

  Each cylindrical member 23 </ b> A is connected by a stirring blade portion 24 to form an outer shell portion 23. At this time, each cylindrical member 23A is connected so that each stirring blade portion 24 rises from the inner surface of the outer shell portion 23 toward the center and has a strip shape extending in the rotation axis direction. Further, the cylindrical members 23A are connected with a gap therebetween.

  An opening portion of the baffle plate portion 25 located on one end side of the outer shell portion 23 forms a receiving port 25 </ b> A of the outer shell portion 23. The gap provided between the cylindrical members 23 </ b> A forms a slit-like drainage hole D penetrating along the baffle plate portion 25 on the side of the receiving port 25 </ b> A from the baffle plate portion 25.

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

  Four rectangular connection members 27 </ b> A are fixed to the baffle plate portion 26. The baffle plate portion 26 and the disc-shaped end surface member 27 are connected by the connecting member 27A. One end portion of the rotating shaft portion 22 </ b> A is connected to the center portion of the end surface member 27.

  The rotation mechanism 22 includes a rotation shaft portion 22A, a ratchet portion 22B, and a lever L1 that form an inclined rotation shaft of the fermenter 21. One end of the second wire W2 is connected to the ratchet portion 22B. The other end of the second wire W <b> 2 is connected to the other end of the lever member 19. For this reason, when the lever L1 is rotated in the standing state, the other end portion 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).

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

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

  In the fermenter 21, one end portion of the inclined rotation shaft portion 22 </ b> A is fixed to the central portion of the end surface member 27. On the other hand, two guide members 29 that guide 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 from rail members 7 provided on the lower surface of the floor member G, and are fixed to a fixed second mounting member 29A.

  In this manner, the fermenter 21 disposed below the floor member G is provided with the receiving port 25A at the upper end of the outer shell 23 in the rotational axis direction and 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 receiving port 25A toward the discharge port 26A. Further, one end portion 11F of the separation plate 11 is inserted into the receiving port 25A of the outer shell portion 23.

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

  In the fermentation apparatus 20 configured as described above, the fermentation chamber C is inclined downward from the receiving port 25A toward the discharge port 26A. For this reason, the stool F received in the fermentation chamber C moves to the discharge port 26A side by gravity. The stool F that has moved to the discharge port 26 </ b> A is prevented from moving downward by the baffle plate 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 but stays in the fermentation chamber C, during which the fermentation process is performed.

  The stool F whose movement toward the discharge port 26 </ b> A by the baffle plate portion 25 is pushed upward in the fermentation chamber C by the stirring blade portion 24 when the fermenter 21 is rotated by the rotation mechanism 22. The stool F pushed up to a certain height falls from the upper surface of the stirring blade portion 24 downward in the fermentation chamber C as shown in FIGS. At this time, since the fermentation chamber C is inclined downward, the stool F deposited at a position close to the baffle plate portion 25 falls to the discharge port 26 </ b> A side of the baffle plate portion 25. Thus, by rotating the fermenter 21, the stool F in the fermentation chamber C gradually moves toward the discharge port 26A, and is finally discharged from the discharge port 26A. For this reason, in this fermenter 20, regardless of the amount of the stool F in the fermentation chamber C, the stool F received in the fermentation chamber C can be discharged sequentially from the outlet while stirring, and the stool F is transferred to the fermentation chamber. The stool F can be continuously fermented with little variation in the residence time in C.

  Moreover, the stool received from the receiving port 25A to the fermentation chamber C by changing the inclination angle of the rotating shaft of the fermenter 21 or changing the number and shape of the stirring blades 24 and the baffle plates 25. The rotation speed of the fermenter 21 until F is discharged from the discharge port 26A can be adjusted. That is, the time during which the stool F stays in the fermentation chamber C can be adjusted. For this reason, the stool F can be retained in the fermentation chamber C for a predetermined period (for example, for one month), and the stool F can be sufficiently fermented. Moreover, since the fermenter 21 rotates and the fall of the stool F is repeated in the fermentation chamber C, the stool F is agitated, so that the microorganisms contained in the stool F are maintained in an aerobic state, and the stool F is It can be fermented well.

  Moreover, in this fermenter 20, since the microbial bed is not accommodated and only the stool F is received and fermented in the fermentation chamber C, the volume for accommodating the microbial bed is not required. Moreover, since the stool F in the fermentation chamber C is automatically discharged | emitted from the discharge port 26A to the storage tank 40 after a fermentation process, the effort which takes out the fermented stool F from the fermentation chamber C is not required.

  Therefore, the toilet facility of Example 1 can be reduced in size, can excrete well, and can reduce maintenance.

  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 U can be discharged | emitted favorably by the slit-shaped drainage hole D penetrated by this part. In this way, since the moisture (urine U) in the fermentation chamber C can be further reduced, the stool F can be stirred well and kept in an aerobic state suitable for treatment with microorganisms. Furthermore, it is possible to maintain a moisture environment in which microorganisms are easier to propagate. Therefore, the stool F can be fermented more favorably.

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

  The urine drying apparatus 30 includes a moisture holding body 31 suspended below the separation plate 11 of the solid-liquid separation apparatus 10 and the fermentation apparatus 20 as shown in FIGS. 1, 15, and 16. As described above, the urine drying device 30 is disposed using the space below the toilet 1 (below the solid-liquid separation device 10 and the fermentation device 20).

  The moisture holder 31 is an annular shape formed of a nonwoven fabric. For this reason, the urine F can be hold | maintained favorably and can be evaporated. A rope 31 </ b> A is inserted into the central space portion of the moisture holding body 31, and a plurality of moisture holding bodies 31 are held. A weight 31B is connected to the lowermost end of the rope 31A in order to prevent the moisture retaining body 31 from falling off and to suspend the rope 31A vertically. The rope 31 </ b> A is connected to a suspension rope 31 </ b> C that is stretched between suspension members 32 that project to the side of the solid-liquid separator 10 and the fermentation apparatus 20.

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

  Therefore, the urine drying apparatus 30 according to the first embodiment can effectively use the space and evaporate the urine satisfactorily without a power source.

  In particular, since the moisture holding body 31 is divided into a plurality of parts, a space can be formed between the moisture holding bodies 31. Thereby, air flows into the space formed between each moisture holding body 31, and evaporation of the urine U from each moisture holding body 31 is accelerated | stimulated. Moreover, since air flows also in the central space part of each water holding body 31, evaporation of the urine U is further promoted.

  Moreover, since the moisture holding body 31 is divided, the urine does not immediately penetrate into the moisture holding body 31 located below. For this reason, the urine is not collected only in the water holding body 31 located at the lowermost end, and the urine can be dispersed and held in each water holding body 31. Therefore, the urine is evaporated from each moisture holding body 31, and the evaporation efficiency can be increased.

  Further, the moisture holding body 31 suspended downward is suspended so as to contact the bottom surface 42 of the storage space in which the urine drying device 30 is stored. For this reason, the urine U which has not been fully held in the moisture holding body 31 and has flowed out to the bottom surface 42 can be absorbed by the other moisture holding bodies 31 and evaporated.

  As shown in FIG. 1, the storage tank 40 is provided below the discharge port 26 </ b> A of the fermentation apparatus 20. The treated stool, which is the treated excrement subjected to the fermentation process in the fermentation chamber C discharged from the discharge port 26A, is stored. The storage tank 40 is partitioned from the storage space of the urine drying device 30 by a partition wall 41. That is, the partition wall 41 is erected below the discharge port 26A. Thereby, the urine U which has not evaporated from the water holding body 31 of the urine drying device 30 and has flowed to the bottom surface 42 of the storage space is prevented from flowing into the storage tank 40. For this reason, since the processed stool stored in the storage tank 40 does not get wet and microorganisms contained therein can be maintained in an aerobic state, the fermentation process is promoted even in a state stored in the storage tank 40. can do.

  An exhaust pipe 50 that discharges odor is connected to the floor member G above the storage tank 40. A fan (not shown) is connected to the exhaust pipe 50 so that exhaust can be forced. For this reason, while storing the solid-liquid separator 10, the fermentation apparatus 20, and the urine drying apparatus 30, the odor of the space which forms the storage tank 40 can be discharged | emitted, and the evaporation of the urine U in the urine drying apparatus 30 is accelerated | stimulated. be able to.

  In the upper side wall of the storage tank 40, when the processed stool is collected in the storage tank 40, the processed stool is carried out, or the solid-liquid separator 10, the fermentation apparatus 20, and the urine drying apparatus 30 are inspected. An inspection port 42 is provided. A lid member 42A is attached to the inspection port 42. The lid member 42 </ b> A is provided with an inlet 43 for mixing ash into the treated stool stored in the storage tank 40.

  The toilet facility of Example 1 configured as described above is used as follows, and excrement is processed.

  When the user of the toilet 1 makes the stool F, the user then turns the lever L1 to the upright state. Then, the stool F separated from the urine U by the solid-liquid separation device 10 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, and from the receiving port 25A of the fermentation device 20 to the fermentation chamber. Drop into C. When the lever L1 is rotated in the standing state, the fermenter 21 of the fermentation apparatus 20 is rotated by a set angle (for example, 5 degrees). Then, the stool F staying in the fermentation chamber C moves upward by the stirring blade portion 24. At this time, a part of the stool F falls from the upper surface of the stirring blade portion 24 downward in the fermentation chamber C. Further, the stool F accumulated at a position close to the baffle plate portion 25 falls to the discharge port 26A side of the baffle plate portion 25. In this way, the stool F gradually moves toward the outlet 26A.

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

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

  By repeating the use of the toilet 1, the stool F can be received from the receiving port 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 fermenter 20 can continuously receive the stool F, perform fermentation, and discharge. Moreover, the stool F can be sufficiently fermented by being retained in the fermentation chamber C for a predetermined period (for example, for one month). Thus, in this toilet facility, the user can process the excrement with no power source by operating the lever L2.

<Example 2>
As shown in FIGS. 17 and 18, the toilet device of the second embodiment is different from the configuration of the first embodiment in the driving unit 115 of the transport mechanism 113 of the solid-liquid separator 110. Other configurations are the same as those of the first embodiment, and the same configurations as those of the first embodiment are denoted by the same reference numerals and detailed description thereof is omitted.

  The joint shaft 15 </ b> J of the driving unit 115 fixes the center portion of the lever member 119. The joint shaft 15J rotates as the lever member 119 rotates around the joint shaft 15J. The lever member 119 is formed in a rectangular shape having arcuate ends. The lever member 119 connects one end portion of the first wire W1 to a lower portion 119A of one arc-shaped end side. 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 is formed with a groove so that the first wire W1 or the third wire W3 extends along both ends of the arc shape.

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

  The first wire W1 is inserted through the floor member G, and the other end is drawn upward from the front side (the 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 portion 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 rotating member 120 forms a groove so that the second wire W2 is along the arc. As the joint shaft 15J rotates, the rotating member 120 rotates so that the arc portion draws a substantially semicircle. The second wire W <b> 2 has one end connected to the ratchet portion 22 </ b> B of the rotation mechanism 22 of the fermentation apparatus 20.

  When the drive unit 115 configured as described above rotates the lever portion L13 of the lever L11 to the upright state, the first wire W1 is pulled upward as shown in FIG. Then, one end of the lever member 119 is pulled upward. As a result, the joint axis J rotates in one direction. Then, each 1st link member 15A rotates to one direction centering on the joint axis | shaft 15J, and each joint member 15K moves to the separation plate 11 direction. Then, each 2nd link member 15B moves the extrusion plate 14 to the one end part 11F side of the separation plate 11. FIG. Further, the removal members 16A and 16B and the scraper 18 integrated with the extrusion plate 14 also move toward the one end portion 11F of the separation plate 11 along the opening portion 12. At this time, while removing the stool F on the separation plate 11 at the saw blade-shaped front side portion of the scraper 18, the stool F in which the removal members 16 </ b> A and 16 </ b> B adhere to the opening 12 or close the opening 12. While removing the stool, the stool F remaining on the separation plate 11 by the extrusion plate 14 can be pushed out from the one end portion 11F of the separation plate 11 and dropped to the receiving port 25A of the fermentation apparatus 20.

  Thus, 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, moisture (urine) in the fermentation chamber C of the fermentation apparatus 20 is reduced. can do. For this reason, in the fermentation chamber C, the stool F can be stirred well and the microorganisms can be maintained in an aerobic state. Therefore, the fermentation process of stool F can be performed satisfactorily. Moreover, the stool F adhering to the opening part 12 or closing the opening part 12 can be favorably removed by the removing members 16A and 16B. For this reason, the opening part 12 can pass the urine U satisfactorily.

  When the lever portion L13 of the lever L11 is rotated to the lying down state, the third wire W3 is pulled upward as shown in FIG. Then, the other end portion of the lever member 119 is pulled upward. As a result, the joint axis J rotates in the other direction. Then, each first link member 15A rotates in the other direction around the joint shaft 15J, and each joint member 15K moves in a direction away from the separation plate 11. Then, each 2nd link member 15B moves the extrusion board 14 to the other end part 11B side of the separation plate 11. FIG. Further, the removal members 16 </ b> A and 16 </ b> B formed integrally with the extrusion plate 14 and the scraper 18 also move along the opening 12 toward the other end 11 </ b> B of the separation plate 11. At this time, even if the stool F remains on the separation plate 11, the pusher plate 14 contacts the stool F on the separation plate 11 when moving from the one end 11 F to the other end 11 B of the separation plate 11. When it comes into contact, the stool F is rotated backward with respect to the moving direction, so that the stool F can be returned to the other end portion 11B without being pushed out from the other end portion 11B of the separation plate 11. Further, when the scraper 18 moves to the other end portion 11B side of the separation plate 11, the stool F on the separation plate 11 can be scraped off at the saw blade-like rear side portion. Further, each removal member 16A, 16B can remove the stool F adhering to the opening 12 or closing the opening 12 when moving to the other end 11B side of the separation plate 11 along the opening 12. it can. For this reason, the opening part 12 can pass the urine U satisfactorily.

  Therefore, the solid-liquid separator 110 can satisfactorily separate the stool F and the urine U (solid-liquid separation) and transport the stool F (convey solids).

  Further, when the lever portion L13 of the lever L11 is turned upright, 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 rotated to the lying down state, the rotating member 120 rotates in the other direction, and the traction force of the second wire W2 is lost, so the second wire W2 is pulled back. At this time, the ratchet portion 22B does not rotate the rotating 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>
As shown in FIG. 19 , the toilet facility according to the third embodiment includes a toilet 1, a solid-liquid separator 60, a urine dryer 80, and a storage tank 90. About the structure similar to Example 1, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

As shown in FIGS. 20 to 22, the solid-liquid separation device 60 includes a separation plate 61, a transport mechanism 63, removal members 66 </ b> A and 66 </ b> B, and a scraper 68. On the lower surface of the floor member G, a pair of rail members 57 are provided extending in parallel with the toilet outlet 3 interposed therebetween. The solid-liquid separator 60 is fixed to the rail member 57 so as to be slidably suspended. For this reason, the solid-liquid separator 60 can be easily removed for installation and maintenance.

  The separation plate 61 has a flat plate shape and is arranged in a horizontal state below the toilet outlet 3. The separation plate 61 has a plurality of openings 62 penetrating in a slit shape arranged in parallel. Each opening 62 extends in the vertical direction from one end 61F of the separation plate 61 to the other end 61B. The separation plate 61 includes a left and right side plate 61A extending upward from the left and right end portions 61L and 61R, and a left and right upper plate 61B extending outward from the upper end portion of the left and right side plate 61A. The left and right upper plates 61B have locking plates 61D fixed to both ends in the vertical direction via spacers 61C. When the left and right ends of the locking plate 61D are locked to the rail member 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 excretion using the toilet 1, and excrement (solid-liquid mixture) discharged from the toilet discharge port 3 is the upper surface of the separation plate 61. Can be received. Of the excreta received on the upper surface of the separation plate 61, the urine U that is a liquid component passes downward from the opening 62, and the stool F that is a solid component 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 an extrusion plate 64 and a drive unit 65. The extrusion plate 64 has a strip shape and can reciprocate between the one end portion 61F and the other end portion 61B, which are the vertical direction of the separation plate 61. The pusher plate 64 extends in a direction perpendicular to the moving direction, that is, in the left-right direction of the separation plate 61. The left and right ends of the extrusion plate 64 extend to the vicinity of the left and right end portions 61L and 61R of the separation plate 61. A pair of first support plates 67 </ b> A are erected along the longitudinal direction of the separation plate 61 below the left and right ends of the extrusion plate 64. The first support plate 67A is provided with a shaft portion 64A at the upper end portion and pivotally supports the upper portion of the extrusion plate 64. The first support plate 67 </ b> A has an inclined side 67 </ b> S formed so that one side descends toward the one end portion 61 </ b> F side of the separation plate 61. The back surface of the extrusion plate 64 is in contact with the inclined piece 67S. For this reason, the extrusion plate 64 is disposed in an inclined state that descends toward the one end 61 </ b> F side of the separation plate 61. Further, the pusher plate 64 pivotally supported by the first support plate 67A can be rotated backward 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 has a flat plate shape elongated in the left-right direction, and is placed on the upper surface of the separation plate 61. The scraper 68 has a lateral width slightly shorter than the lateral width of the separation plate 61. Further, the scraper 68 is formed in a saw blade shape on the front and rear sides. Further, when the scraper 68 is placed on the separation plate 61, a slit-like through hole 68 </ b> A is provided at a position corresponding to the opening 62 of the separation plate 61.

  The removal 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 forms a through hole through which the connecting member 15L is inserted. 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 removal members 66 </ b> A, 66 </ b> B, 66 </ b> C pass through the through hole 68 </ b> A of the scraper 68 placed on the upper surface of the separation plate 21 and the opening 12 of the separation plate 21 and protrude below the separation plate 11. The removal members 66B and 66C are integrally formed with 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 one end portion 61F side of the separation plate 61 comes into contact with the back surface of the extrusion plate 64.

  The removal member 66A formed integrally with the first support plate 67A and the removal members 66B and 66C formed integrally with the second support plate 67B are below the separation plate 61 by a rod-like connecting member 15L inserted into the through hole. It is connected. Each removal member 66A, 66B, 66C can reciprocate along each opening 62 in a state of being inserted into each opening 62 formed in a slit shape. Each removal member 66A, 66B, 66C is connected to and integrated with the extrusion plate 64 via the connection member 15L and the first support plate 67A. For this reason, the extrusion plate 64, the removal members 66A, 66B, 66C, and the scraper 68 are reciprocated between the one end portion 61F and the other end portion 61B of the separation plate 61 together.

  The drive unit 65 includes a cylindrical outer casing 65A provided at both ends, a rod-like rod member 65B that is slidably housed in each outer casing 65A, and that enters and exits 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 this push-pull cable is connected to a connection member 65D connected to a removal member 66C. 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 an opening 69A provided in an operation box 69 fixed to the wall surface of the toilet room in which the toilet 1 is installed and extending in the vertical direction.

  When the drive unit 65 configured as described above moves the lever L3 to the upper end of the opening 69A of the operation box 69, as shown in FIGS. 21 and 22, the one of the rod members 65B of the push-pull cable is used. Most of it is drawn into the outer casing 65A. As a result, the pusher plate 64, the removal members 66A, 66B, 66C, and the scraper 68 move to the one end portion 61F side of the separation plate 61. At this time, the removal member 66A, 66B, 66C adheres to the opening 62 or closes the opening 62 while scraping the stool F on the separation plate 61 at the saw blade-shaped front side of the scraper 68. While removing the stool F, the stool F with the extrusion plate 64 remaining on the separation plate 61 can be pushed out from the one end 61F of the separation plate 61 and dropped into the storage tank 90.

  Thus, since the stool F separated from the urine U and remaining on the separation plate 61 is pushed out from the one end portion 61F of the separation plate 61 by the extrusion plate 64, moisture (urine) in the storage tank 90 can be reduced. .

Moving the lever L3 at the lower end portion of the opening portion 69A of the operation box 69, as shown in FIGS. 20 to 22, one of the rod members 65B of the push-pull cable protrudes from the distal end of the outer casing 65A. As a result, the extrusion plate 64, the removal members 66A, 66B, and 66C, and the scraper 68 move to the other end portion 61B side of the separation plate 61. At this time, even if the stool F remains on the separation plate 61, the pusher plate 64 moves to the stool F on the separation plate 61 when moving from the one end portion 61F to the other end portion 61B side of the separation plate 61. When abutting, the stool F is rotated backward with respect to the moving direction, so that the stool F can be returned to the other end 61B without being pushed out from the other end 61B of the separation plate 61. Further, when the scraper 68 moves to the other end portion 61B side of the separation plate 61, the stool F on the separation plate 61 can be scraped off at the saw blade-shaped rear side portion. Further, each removal member 66A, 66B, 66C also removes the stool F that adheres to or closes the opening 62 when moving to the other end 61B side of the separation plate 61 along the opening 62. be able to. For this reason, the opening part 12 can pass the urine U satisfactorily.

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

As shown in FIG. 19 , the urine drying apparatus 80 includes a moisture holding body 81 and a phosphorus adsorbing body 82. The phosphorus adsorbent 82 is housed in a container 83 that is disposed below the toilet 1 and below the solid-liquid separator 60 and above the moisture holder 81. The container 83 has a bottom plate portion 84 provided with a 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 adsorbent 82 is formed of a waste medium that carries charcoal or a degrading bacterium that decomposes urine, a sphere 82A that has high adsorptivity of phosphorus such as red crust, and a rod-shaped body 82B that covers the sphere 82A.

  The moisture holding body 81 has a flat plate shape, and a plurality of the moisture holding bodies 81 are suspended below the discharge port 84 </ b> A of the container 83 with a space in the vertical direction in a state of being spread in the horizontal direction. For this reason, air flows above and below the moisture holder 81.

  The urine drying device 80 configured as described above retains moisture from the urine U discharged from the toilet discharge port 3 and separated from the stool F by the solid-liquid separation device 60 via the container 83 in which the phosphorus adsorbent 82 is stored. The body 81 can hold it. In addition, the water holding body 81 can sufficiently hold the urine U, is easily contacted with air, and evaporates the urine U held by the water holding body 81 well in the space below the toilet 1. be able to.

  Therefore, the urine drying apparatus 80 of Example 3 can also effectively use the space and evaporate the urine satisfactorily without a power source.

  In addition, the urine drying apparatus 80 can easily collect phosphorus contained in the urine U because the phosphorus adsorbent 82 adsorbs 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 even while passing through the container 83 while the urine stays in the container 83.

  An opening 86 for exchanging the phosphorus adsorbent 82 and the moisture holder 81 is provided on the side wall of the storage space below the toilet 1 in which the urine drying device 80 is stored. A lid member 86 </ b> A is attached to the opening 86.

  The storage tank 90 stores the stool F pushed out from the one end 61 </ b> F of the solid-liquid separator 60. The storage tank 90 is partitioned by a partition wall 41 from a storage space in which the urine drying device 80 is stored. For this reason, the urine U which has not evaporated from the water holding body 81 of the urine drying device 80 and has flowed to the bottom surface 42 of the storage space is prevented from flowing into the storage tank 90. Therefore, the stool F stored in the storage tank 90 is slowly subjected to a fermentation process by the microorganisms contained therein.

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

  When the user of the toilet 1 makes the stool F, the user then 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 separation device 60 and remaining on the separation plate 61 is pushed out from the one end portion 61F of the separation plate 61 by the pushing plate 64 and falls into the storage tank 90. The stool F that has fallen into the storage tank 90 is gradually fermented.

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

  When the user moves the lever L3 to the lower end of the opening 69A of the operation box 69, the pusher plate 64 of the solid-liquid separation device 60 moves to the other end 61B side of the separation plate 61. Thus, the extrusion plate 64 reciprocates between the one end portion 61F and the other end portion 61B of the separation plate 61, and the removal members 66A, 66B, 66C and the scraper 68 also reciprocate, so that the opening 62 The stool F adhering to or closing the opening 62 is removed. For this reason, the urine U excreted after the toilet 1 is used can pass through the opening 62 of the separation plate 61 satisfactorily. That is, the solid-liquid separation device 60 can separate the stool F and the urine U well. Thus, by operating the lever L3, excrement can be processed without a power source.
