Description

  The present invention relates to a solid-liquid separation device and a flush toilet that can separate and reuse a solid content and a liquid content of filth.

Box-type simple toilets will be installed at event venues and construction sites. This simple toilet stores filth in a state where liquid and solid are mixed in a filth tank provided below the toilet. In addition, even in areas where sewage is not widespread, those that store filth in a filth tank provided below the toilet are also used.
Patent Document 1 describes a tray for separating a liquid and a solid for a toilet stored in such a mixed state.

The solid-liquid separation device described in Patent Document 1 is pivotally fixed so that a tray formed in a concave shape on the upper surface disposed below the toilet defecation port is pivoted on one end side. The top surface of the pan is dropped into water and flows down and drops from the drain port toward the opening of the drain pipe.On the other hand, when the solid is rotated by the lever, the pan rotates and falls down toward the defecation pipe. It separates liquid and solid.
Japanese Utility Model Publication No.59-151983

  However, in the solid-liquid separation device described in Patent Document 1, since the receiving tray that receives the filth is formed in a concave shape on the upper surface, the liquid overflowing from the receiving tray flows to the drainage pipe. It is assumed that when the pan is rotated, the liquid flows together with the solid to the defecation pipe.

  Then, an object of this invention is to provide the solid-liquid separation apparatus and flush toilet which can isolate | separate a liquid part and a solid part firmly.

  The solid-liquid separation device of the present invention includes a filter plate provided below a toilet stool outlet, a guide plate disposed in an inclined state below the filter plate, and a lower end of an inclined surface of the guide plate. A drainage pipe provided with a drainage port at a position, and a rotation mechanism for rotating the guide plate together with the filter plate are provided.

  The solid-liquid separation device of the present invention separates solids and liquids with a filter plate. The liquid component filtered by the filter plate falls on a guide plate disposed below the filter plate. When the liquid that has fallen on the guide plate is guided by the inclined surface of the guide plate and reaches the lower end, it enters the drain pipe from the drain port. Then, by rotating the guide plate together with the filter plate by the rotation mechanism, the solid content remaining on the filter plate falls as it is. Therefore, the liquid component can be taken out from the drain pipe, and the solid component can be dropped below the filter plate and the guide plate.

The solid content is collected on the filter plate formed in a substantially V shape, and the liquid content is collected on the guide plate formed in a substantially V shape along the inclined surface at the lower end. Since the drainage pipe is provided at the lower end of the guide plate, the collected liquid enters the drainage pipe from the drainage port. Then, by rotating the guide plate together with the filter plate using the drain pipe as a rotation support shaft, the solid content can be dropped from the inverted filter plate.

  The filter plate and the guide plate are provided with a weight portion for directing upward, and the rotation mechanism is provided with a gear with a ratchet mechanism that transmits a rotational driving force to the filter plate and the guide plate. Then, when the filtration plate and the guide plate are rotated upside down and the solid content is dropped, the filter plate and the guide plate can be rotated in the rotation direction at once due to the weight of the weight portion to be restored to the original state.

  A flush toilet according to the present invention includes a solid-liquid separator according to the present invention, a urinal tank for storing the separated liquid, a pump for pumping up the liquid stored in the urinal and reusing it as flush water for the toilet. It is provided with. According to this invention, the liquid component can be taken out from the drainage pipe, and the solid component can be dropped below the filter plate and the guide plate. Further, the liquid component can be reused as washing water.

  In the present invention, the liquid component can be taken out from the drain pipe, and the solid component can be dropped below the filter plate and the guide plate, so that the liquid component and the solid component can be separated firmly. Further, the liquid component can be reused as washing water.

  A flush toilet according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a flush toilet according to an embodiment of the present invention. FIG. 2 is an AA arrow view of the flush toilet shown in FIG.

  A flush toilet 1 shown in FIG. 1 and FIG. 2 includes a Japanese-style toilet 2, a solid-liquid separator 3 that separates liquid and solid matter of filth, and a flush mechanism 4 for washing the toilet 2. ing.

The toilet 2 is formed with a defecation opening 21 that opens downward.
The solid-liquid separation device 3 includes a rotating unit 31 that receives filth and separates it into a solid component and a liquid component, and a rotating mechanism 32 that rotates the rotating unit 31.

  The rotating unit 31 includes two disks 311, a substantially V-shaped filter plate 312 sandwiched between the disks 311, a substantially V-shaped guide plate 313 positioned below the filter plate 312, and the guide plate 313. A drainage pipe 314 located at the lower end, a weight part 315 held between the lower parts of the disk 311, and a holding metal fitting 316 for hanging the entire rotating part are provided.

The disk 311 is formed in a circular shape having a diameter of about 30 cm. A drainage pipe 314 passes through the center of the disk 311.
The filter plate 312 is provided with through-holes 312a of about 1 cm arranged in columns and rows. The filter plate 312 is disposed between the disks 311 so as to spread obliquely upward about the drainage pipe 314. The filter plate 312 can be a punching metal or a plate that has been drilled with a drill. The filter plate 312 can be a mesh plate or a fine mesh, but it is preferable to use punching metal or the like because dirt enters the joints and is difficult to remove.

The guide plate 313 is disposed between the disks 311 so as to be spaced obliquely upward from the filter plate 312 with a predetermined distance from each other and centering on the drainage pipe 314.
The drainage pipe 314 is provided with a drainage port 314a formed in an elongated hole along the axis at the lower end of the guide plate 313 located between the filter plate 312 and the guide plate 313. One end of the drainage pipe 314 is closed, and a bent L-shaped tube 314b is provided at the other end.
The weight portion 315 is provided to stabilize the filter plate 312 and the guide plate 313 with the filth receiving side facing upward.
The holding metal fitting 316 is a pair of elongated plates that are suspended from both sides of the toilet bowl 2. The holding metal fitting 316 is rotatably held by a bearing (not shown) interposed between the drainage pipe 314 and the drainage pipe 314.

The rotation mechanism 32 is an endless wound around a first sprocket 321 provided in the drainage pipe 314, a second sprocket 322 that drives the first sprocket 321, and the first sprocket 321 and the second sprocket 322. And a chain 323.
The first sprocket 321 is a chain gear with a ratchet mechanism. The second sprocket 322 is provided with a handle 322a at a position eccentric with respect to the rotation axis.

  The flushing mechanism 4 includes a urinal tank 41, a stool tank 42, a water tank 43, a first pump 44 that pumps urine from the urinal tank 41, and a second pump 45 that pumps water from the water tank 43. Yes.

  The urinal tank 41 is disposed below an L-shaped tube 314 b provided at the end of the drainage pipe 314. The stool tank 42 is disposed below the rotating unit 31. The water tank 43 stores tap water such as tap water.

The first pump 44 and the second pump 45 are electric pumps that operate by stepping.
Connected to the first pump 44 are a urine water absorption hose 44 a that hangs down toward the urinal tank 41 and a first washing hose 44 b that extends into the toilet 2. A ring-shaped float 44c is provided at the tip of the urine water absorption hose 44a. The second pump 45 is connected to a water-water absorption hose 45 a that hangs down toward the water tank 43 and a second washing hose 45 b that extends into the toilet 2.
In the present embodiment, the first pump 44 and the second pump 45 are electric pumps. However, in the case of a simple toilet installed in a place where electricity cannot be supplied, a manual pump is used. Is also possible.

  The use state and operation | movement of the flush toilet which concerns on embodiment of this invention comprised as mentioned above are demonstrated based on drawing.

The filth excreted from the user passes through the stool 21 of the toilet 2 and falls to the rotating part 31. In the rotating unit 31, the solid content of the dropped filth falls to the filter plate 312 and stays around the lower end along the inclined surface on the filter plate 312. The liquid also flows to the filter plate 312, but since the filter plate 312 is provided with a through hole 312a, it drops from the through hole 312a to the guide plate 313. The liquid dropped from the through-hole 312a is collected by flowing along the guide plate 313 and flows into the drain pipe 314 from the drain port 314a located at the lower end. Since both sides of the guide plate 313 are sandwiched between the disks 311, the liquid component can be guided to the lower end without leakage.
The liquid flowing in the drainage pipe 314 flows and accumulates from the L-shaped tube 314b to the urinal tank 41.

  When the user defecates, the user rotates the handle 322a, whereby the second sprocket 322 rotates. The rotation of the second sprocket 322 is transmitted to the first sprocket 321 by the rotation of the endless chain 323, and the rotating unit 31 starts rotating around the drainage pipe 314 held by the holding metal fitting 316.

  As the rotating unit 31 rotates, one surface side of the filter plate 312 changes from the ascending inclined surface to the horizontal surface and becomes the descending inclined surface. When one surface side of the filter plate 312 becomes a downward inclined surface, the solid component starts to move, slides down from the end, and is accumulated in the stool tank 42. A solid content containing a large amount of moisture has high adhesiveness, but if the rotating portion 31 is rotated halfway by the user's operation of the handle 322a, the solid content is upside down. However, it can be dropped from the filter plate 312 to the stool tank 42.

  Due to the half rotation of the rotating part 31, the solid part slides down from the filter plate 312 and the weight part 315 moves upward, so that the center of gravity of the rotating part 31 moves to a higher position. Since the first sprocket 321 includes a ratchet mechanism, the rotating unit 31 having a higher center of gravity automatically starts to rotate in the rotation direction, and returns to the original state while causing the first sprocket 321 to idle. Therefore, at the stage where the rotation of the handle 322a is half-turned, the user can recognize that it is not necessary to further rotate by visually recognizing the rotating part 31 that automatically returns to the original state. The excessive rotation of 322a can be suppressed. The solid content remaining on the filter plate 312 can be processed by such a simple operation.

  When the operation of the handle 322a is completed, the first pump 44 is stepped on. The first pump 44 is activated by this stepping. The liquid stored in the urinal tank 41 is pumped up from the tip of the urine water absorption hose 44 a connected to the first pump 44. The liquid thus pumped flows into the toilet bowl 2 through the first washing hose 44b, thereby washing the inner surface of the toilet bowl 2.

  Since the float 44c is provided at the distal end portion of the urine water absorption hose 44a, the distal end portion of the urine water absorption hose 44a is in a floating state. Therefore, since only the supernatant can be pumped up while avoiding the settled dirt, it is possible to prevent the toilet 2 from being soiled by pumping the settled dirt. The liquid that has washed the toilet 2 flows from the defecation opening 21 to the filter plate 312, falls from the through hole 312 a of the filter plate 312 to the guide plate 313, passes through the drainage pipe 314, and is stored again in the urinal tank 41. In this way, the waste liquid is recycled.

  When liquid is not accumulated in the urinal tank 41 or when it is desired to wash the toilet 2 with clean water, the water stored in the upper water tank 43 is taken into the upper water absorption hose by stepping on the second pump 45. It is pumped up from 45a and flows to the toilet 2 through the second washing hose 45b. By doing so, cleaning with clean water is also possible.

  In this way, the liquid content of the filth filtered by the filter plate 312 falls on the guide plate 313 disposed below the filter plate 312, travels along the inclined surface of the guide plate 313, and drains from the drain port 314 a. Since the solid content of the filth remains on the filter plate 312, the liquid content and the solid content can be firmly separated. Then, by rotating the guide plate 313 together with the filter plate 312 that forms the rotating portion 31 by the rotation mechanism 32, the solid content remaining on the filter plate 312 can be dropped directly below, so that only the solid content is easy. Can be stored.

  In addition, since the guide plate 313 is formed in a substantially V shape, the liquid component dropped from the filter plate 312 can be concentrated at the lower end, so that it can be reliably collected in the drainage pipe 314. Moreover, since the filter plate 312 is formed in a substantially V shape and is disposed at a predetermined interval from the guide plate 313, the filter plate 312 and the guide plate 313 can be disposed in a compact manner.

As mentioned above, although embodiment of this invention has been described, this invention is not limited to the said embodiment, For example, in this Embodiment, the filter plate 312 is formed in the substantially V shape. However, it may be a tray having a peripheral wall that prevents solids from leaking out. Further, in this embodiment, the guide plate 313 is formed in a substantially V shape, but is disposed in a state inclined below the filter plate, and a drainage pipe provided with a drainage port at the lower end of the guide plate. If it is arrange | positioned, a simple flat plate may be sufficient.
Further, a weight portion 315 is provided between the lower portions of the two disks 311, but the center of gravity of the rotating portion 31 is formed by forming the thickness of the lower portion of the two disks 311 thicker than the upper thickness. May be adjusted.

  The present invention is suitable for flush toilets because it separates solids and liquids and can be used as wash water, and is ideal for simple toilets installed at event venues and construction sites. .

It is the figure which looked at the flush toilet which concerns on embodiment of this invention from the front. It is an AA arrow directional view of the flush toilet shown in FIG.
