Description

  The present invention relates to a solid-liquid separator that separates waste liquid containing solids such as garbage into solids and liquids.

  Conventionally, this type of solid-liquid separation device is used in a garbage disposal device that crushes and dehydrates garbage generated in a kitchen or the like (see, for example, Patent Document 1). FIG. 3 shows a conventional solid-liquid separator described in Patent Document 1. In FIG.

  This solid-liquid separation device includes a protrusion 1 that protrudes to the outer periphery at a predetermined interval (for example, a protrusion height of 10 mm), a protrusion 2 that protrudes to the inner periphery, and a bifurcated protrusion that extends to the inner peripheral surface. A cylindrical strainer 5 is configured by laminating a plurality of circular ring bodies 4 forming the pieces 3.

  The first horizontal member 7 has a plurality of circular ring bodies 4 mounted thereon and is engaged with the protrusions 2 on the surface so that the circular ring bodies 4 are provided with gaps (for example, 0.5 mm). A plurality of engaging portions 6 are formed on each side surface in the circumferential direction of the strainer 5 and in the longitudinal direction.

  A plurality of second horizontal members 8 are mounted across a pair of circular rings 4 at both ends, and are engaged with the bifurcated projecting piece 3 to restrict the protruding part 2 from being disengaged from the engaging part 6. . The connecting body 10 connects the first horizontal member 7 and the rotating shaft 9.

  The container 11 forms a substantially cylindrical space larger than the strainer 5 so as to lie sideways, and incorporates the strainer 5 so as to be rotatable. The inflow port 12 is located outside the strainer 5 and flows in the solid liquid that opens to the end surface of the container 11 that is deformed so as to expand outward. The drain port 13 is located inside the strainer 5 and drains the liquid that has passed through the gap of the strainer 5 to the end surface of the container 11.

  The scraper 14 scrapes off solid matter adhering to the circular ring body 4 with its tip entering each gap of the strainer 5. The spacer 15 adjusts the position of the scraper 14 in each gap of the strainer 5.

  The take-out port 16 discharges the solid matter scraped by the scraper 14 opened on the peripheral surface of the container 11 to the outside. A lid 18 is attached to the hinge 17 at the edge of the outlet 16, and the lid 18 is pressed against the scraper 14 by a pressurizing means 19 (spring).

  The operation of the solid-liquid separator configured as described above will be described.

The solid-liquid separator first crushes raw garbage charged with a crusher (not shown), and then the mixed solid-liquid flows into the container 11 from the inlet 12. And since the rotating shaft 2 rotated by a drive part (not shown) rotates the strainer 5 via the coupling body 10 and the 1st horizontal member 7, the protrusion part 1 makes a solid substance (crushed garbage). Raise it. Thereafter, the solid matter riding on the protrusion 1 and the solid matter adhering to the outer surface of the circular ring body 4 are peeled off from the strainer 5 by the scraper 14. The solid material peeled off by the scraper 14 is dehydrated by the lid 18 pressed by the pressurizing means 19 and collected (discharged) from the outlet 16 to an external drying processing means (not shown). In addition, the liquid (tap water, garbage soup, etc.) adhering to the solid matter passes through the gap of the strainer 5 by its own weight and is drained from the drain port 13.
Japanese Patent No. 3600474

  However, the conventional solid-liquid separation device has a problem in that the size of the solid matter that the protrusion 1 lifts up is limited by the height of the protrusion 1, so that a crusher that crushes the solid is necessary. It was.

  Specifically, a solid material having a size equivalent to that of the inlet 12 (for example, a diameter of 30 mm) cannot be lifted up by the protrusion 1 and the solid matter is clogged in the vicinity of the inlet 12 and does not flow. The clogged solids lock the movement of the strainer 5.

  On the contrary, since the fine solid matter generated when the crusher crushes the solid matter passes through the gap of the strainer 5 and is drained from the drain port 13, it is inevitable that the water quality is deteriorated. The commercially available product has a dry weight recovery rate of about 70%, and fine solids with a dry weight recovery rate of about 30% are discharged from the drain port 13, thus deteriorating the quality of the waste water.

  In addition, if the protrusion height of the protrusion part 1 is made high, the shape of the container 11 will become large if the diameter of the circular ring body 4 is not made small by the part which made the protrusion part 1 high. If the shape of the container 11 is not changed, the drainage port 13 also becomes smaller as the diameter of the circular ring body 4 is reduced, so that the drainage performance is deteriorated.

  This invention solves the said subject, and it aims at providing the solid-liquid separation apparatus which does not require the crusher of a solid substance.

  In order to solve the above-described conventional problems, a solid-liquid separation device according to the present invention includes a rotation shaft that is disposed substantially horizontally, a container that forms a substantially cylindrical space around the rotation shaft, and a rotation shaft. The rotating vessel is composed of rotating blades that extend to the vicinity of the inner periphery of the container and that are curved so that a central portion in the extending direction protrudes in the rotating direction of the rotating shaft, and flat rails that are stacked at a predetermined interval. A strainer disposed across the shaft and having both ends fixed to the container; a drain opening for draining the liquid that has been opened below the strainer of the container and passed through the gap of the strainer; And an inlet opening above the container on the side where the rotary blades rotate downward, and is sandwiched between the strainer gaps. Said times It is to move in the rotational direction by scraping solids deposited on the strainer by the rotation of the blades.

  First, wastewater containing garbage is put into a container from the inflow port, the liquid passes through the gap of the strainer and drains from the drainage port, and the garbage which is a solid matter accumulates on the upper surface of the strainer. And a rotary blade rotates and conveys a solid substance along a strainer upper surface. At the same time, the liquid adhering to the solid material passes through the gap between the strainers by its own weight and drains from the drain port. Then, the rotating rotor blades take out the solid matter from the outlet.

  On the other hand, when the rotating blades rotate and move through the gap between the strainers, the angle between the rotating blades and the upper surface of the strainer is unlikely to be a narrow acute angle. Can be prevented.

  As described above, according to the present invention, there is provided a solid-liquid separator that does not require a solid crusher and can process hard solids without locking.

  According to a first aspect of the present invention, there is provided a rotating shaft disposed substantially horizontally, a container having a substantially cylindrical space centered on the rotating shaft, and extending from the rotating shaft to the vicinity of the inner periphery of the container. It is composed of rotating blades that are curved so that the central part of the current direction protrudes in the rotating direction of the rotating shaft, and flat rails that are stacked at a predetermined interval. A strainer fixed to the container, a drain opening for draining the liquid that has been opened below the strainer of the container and passed through the gap between the strainers, and a solid opening that is opened above the container on the side where the rotating blades rotate upward. An inlet for injecting liquid, and an outlet opening above the container on the side where the rotating blades rotate downward, and adhere to the strainer by the rotation of the rotating blades sandwiched between the gaps of the strainer Was a solid scraped by solid-liquid separation device for moving the rotating direction.

  First, a solid liquid consisting of garbage and liquid is introduced into the container from the inlet, the liquid passes through the gap of the strainer and is drained from the drain port, and the garbage which is solid matter accumulates on the upper surface of the strainer. The rotating blades that have started rotating begin to protrude upward through the gaps of the strainer, and transport solids along the upper surface of the strainer while moving above the strainer. Thereafter, the rotating rotating blade starts to sink gradually from the portion near the rotating shaft into the gap of the strainer, and the tip of the remaining remaining rotating blade pushes out the solid matter to the outlet and discharges it.

  In this operation, since most of the rotating blades protrude above the strainer, a large solid material can be conveyed as it is, and it is not necessary to reduce the solid material before it is introduced from the inflow port, so a crusher is unnecessary. If the solid matter is not crushed beforehand, fine solid matter will not be generated, so that the dry weight recovery rate can be increased, and deterioration of the water quality discharged from the drain outlet can be prevented. In addition, since the solid-liquid separation process is performed with a large solid material, the gap between the strainers can be widened and the rotating blades can also be formed of a thick flat plate, facilitating assembly and reducing the assembly cost.

  Further, since the rotating blade protrudes in the rotating direction and is curved, the angle between the rotating blade 27 and the strainer 23 that has sunk in the gap of the strainer due to the rotation of the rotating blade 23 can be secured to a predetermined angle or more, and the solid matter is strainer. 23, it is possible to prevent the rotary blade 27 from being locked between the upper surface and the rotary blade 27, and the solid matter can be smoothly discharged from the outlet 41 to the outside.

  In the second invention, in particular, since the rotating blades of the first invention are formed of a plurality of sheets around the rotation axis, even if the rotating blades protruding from the strainer have passed through the strainer gap, they will come next. Other rotating blades begin to protrude immediately from the strainer gap to transport solids along the upper surface of the strainer. As a result, even when a large amount of garbage is introduced into the container from the inlet, the solid-liquid separation process can be performed in a short time.

  In the third invention, in particular, a rail guide plate that is separated from the rotary shaft of the first invention and is connected to the rail and configured to circulate around the rotary shaft, and the rail guide plate are sandwiched between the rail guide plates. A plurality of rotating blades fixed to the rotating shaft, and rib portions protruding inward from both end faces of the container along the rail guide plate located below the cylindrical container, Of the plurality of rotating blades, the rotating blades positioned outside in the stacking direction are supported from the outside in the stacking direction toward the inside.

  With this configuration, the plurality of rotating blades rotate while being supported by the rail guide plate and the rib portion, and thus the plurality of rotating blades can be rotated without being deformed in the stacking direction. In addition, the rotating blades on the outer side in the stacking direction do not contact the entire inner side of the cylindrical container end surface, and a plurality of rotating blades can be rotated by position restriction due to partial contact with the rib portion. While reducing the load of the drive part to drive, the friction concerning a rotary blade can be made small.

  According to a fourth aspect of the invention, in particular, the outlet according to the first aspect of the invention is provided with a lid provided at the upper end of the outlet so as to be rotatable at the outlet, and a strainer from the outside on the lid. Pressurizing means for applying a pressing force to the side, so that the tip of the rotary blade that pushes out the solid matter to the outlet and the lid pressed by the pressurizing means compress the solid matter into the solid matter. Squeeze adhering liquid (such as juice or tap water) and dehydrate.

  In addition, when wastewater containing a large amount of solids flows into the container from the inlet, the large amount of wastewater cannot pass through the strainer at a stretch, and a part of the wastewater expands the upper surface of the strainer and reaches the outlet. Since the internal air pressure rises, a force that tries to discharge the waste water containing solid matter from the outlet acts on the lid. However, the lid pressed by the pressurizing means prevents the lid from being pushed open due to an increase in the air pressure in the container, so that it is possible to prevent the drainage containing solid matter from leaking out from the outlet.

  In the fifth aspect of the invention, in particular, since the cross-sectional area of the charging passage that leads from the inlet to the container of the first invention increases from the inlet toward the lower container, Since dust hardly touches the charging passage and falls and accumulates on the upper surface of the strainer, there is an effect that the charging passage is not easily contaminated.

  In the sixth aspect of the invention, in particular, since the outlet from the charging passage of the first aspect of the invention into the container forms a square cut portion on the downstream side in the rotation direction of the rotary blade, it is charged into the container from the inlet. In the case of a large amount of solid matter that the solid liquid is accumulated up to the charging passage, the rotary blade cuts and separates the solid matter conveyed along the upper surface of the strainer, so that the load on the drive unit can be reduced. Then, the solid matter in the charging passage falls and accumulates on the upper surface of the strainer and is conveyed by the next rotating blade.

  In the seventh aspect of the invention, in particular, the inflow port or charging passage of the first aspect of the invention is opened in a rectangular shape that shortens the length of the rotating shaft in the diametrical direction, so that long solids are charged in the diametrical direction of the rotating shaft. Since they collide with the passage, they are aligned on the upper surface of the strainer in the cylinder direction of the container. As a result, the rotary blades that move through the gaps of the strainer can convey the solid matter along the upper surface of the strainer.

  In the eighth aspect of the invention, in particular, the length in the container cylinder direction of the inlet or the input passage of the first invention is shorter than the length of the container itself in the cylinder direction, so that a large amount of solid liquid is introduced from the inlet. In this case, the solid matter accumulates from the upper surface of the strainer toward the inflow port, and the solid matter hardly accumulates near the end of the container. For this reason, tap water and drainage that flow into the container from the inlet can pass through the gap between the strainers near the end of the container and drain from the drain, so even if a large amount of solid liquid is introduced into the inlet, And leakage of drainage from the outlet.

  In the ninth aspect of the invention, in particular, the drain plug of any one of the first to eighth aspects is provided with a drain passage through which liquid passes, so that even if the drain plug is inserted into the inlet, Drainage can be drained, and drainage generated during cooking can be discharged freely.

(Embodiment 1)
Embodiment 1 of the present invention will be described with reference to FIGS. FIG. 1 is a configuration diagram of a solid-liquid separation apparatus according to Embodiment 1 of the present invention, and FIG. 2 is a cross-sectional view of the solid-liquid separation apparatus showing the XX cross section of FIG.

1 and 2, a hexagonal column rotating shaft 21 is connected to a drive unit 22 made of a geared motor and is provided horizontally. The strainer 23 uses, for example, a plate-like rail 24 having a thickness of 1.0 to 1.5 mm and a height of 5 to 10 mm, and a plurality of the rails 24 are arranged at a predetermined interval (for example, 0.5 to 1.6 mm). The upper surface is bent upward, and rail communication ports 25 are opened at both ends of the rail 24.

  The rail guide plate 26 has the same flat plate shape as the rail 24, is formed integrally with the rail 24, and is configured so as to circulate around the rotary shaft 21 while being connected to the rail 24 in a state of being separated from the rotary shaft 21. Yes.

  The rotary blade 27 has a flat plate shape with a thickness of 0.4 to 1.5 mm and a width of 5 to 10 mm, for example, and is assembled so as to be positioned between the strainers 23. The tip is formed so as to pierce upward, and the center portion is curved so as to protrude in the rotation direction. The rotary blades 27 are formed in three pairs at equal intervals with respect to the rotary shaft 21, and a hexagonal hole 28 is opened at the center of rotation, and the hexagonal rotary shaft 21 is inserted into the hexagonal hole 28. . The rotary blade 27 is attached so as to extend from the rotary shaft 21 to the vicinity of the inner peripheral surface of the container 30, and has a maximum protruding length of 30 mm or more when it rotates and protrudes on the strainer 23.

  The strainer 23 has an elongated flat plate shape, and is installed across the rotation shaft 21 so as to incline upward in the rotation direction of the rotary blade 27 toward the outlet 42 described later. It is fixed to. The rail guide plate 26 is formed integrally with the strainer 23 and is configured in the vicinity of the tip (free end) of the rotary blade 27 so as to go around the rotary shaft 21 in a row with the strainer 23.

  The spacer 29 sets the gap between the rotary blades 27 to a width equivalent to that of the rail 24, for example, and is inserted into the rotary shaft 21 alternately with the rotary blades 27.

  The container 30 forms a substantially cylindrical space with the rotation shaft 21 as the center, and incorporates the rotary blades 27 so as to be rotatable with respect to the rotation shaft 21. A plurality of insertion openings 31 for insertion are opened at two locations. The container communication port 32 is open to the insertion port 31.

  After both ends of the rail 24 are inserted into the insertion port 31, a fixing bar 33 is inserted into the rail communication port 25 and the container communication port 32, and fixing means 34 (screws, E-rings, etc.) are attached to both ends of the fixing bar 33. Thus, both ends of the rail 24 are fixed to the container 30.

  The rib portion 35 is formed so as to protrude inside the end surface of the substantially cylindrical container 30, is provided at a position corresponding to the rail 24 and the rail guide plate 26, and positions the rotary blades 27 </ b> A positioned at both ends of the strainer 23. is doing. In FIG. 1, the rib portion 35 is hidden by the rail 24 and the rail guide plate 26, but as shown in FIG. 2, at the positions corresponding to the rail 24 and the rail guide plate 26 on both end faces of the cylindrical container 30, respectively. It is provided.

  The rib portion 35 may be a belt-like convex portion along the position corresponding to the rail 24 and the rail guide plate 26, or a plurality of ribs 35 arranged along the position corresponding to the rail 24 and the rail guide plate 26. May be larger than the rail 24 and the rail guide plate 26.

  Further, the integrated body of the rail 24 and the rail guide plate 26 and a plurality of rotary blades 27 are stacked, and the stacked body is configured so that the integrated body of the rail 24 and the rail guide plate 26 is located on the outermost side in the stacking direction. The outermost integral member in the stacking direction may be substituted for the rib portion 35. When such a laminated body is once constructed and then mounted in the container 30, it is somewhat permissible to damage the integrated object located on the outermost side of the laminated body during assembly of the apparatus.

  The drain port 36 is located below the strainer 23, and the upper and lower portions of the rib portion 35 are opened on the end surface of the cylindrical container 30 to increase the drainage capacity by increasing the opening area. Drain the liquid that has passed through.

  The inflow port 37 has, for example, a circular shape with a diameter of 60 mm, is located above the strainer 23 on the side where the rotary blades 27 rotate upward, is opened on the peripheral surface of the container 30, and is connected to the sink 38 of the sink. Inflow of solid liquid consisting of garbage and waste water. The passage sectional area of the inflow port 37 is equal to or less than that of the drain port 36.

  The introduction passage 39 is configured to increase the cross-sectional area from the inlet 37 toward the lower container 30 and opens in a rectangular shape (for example, approximately 60 mm × approximately 120 mm) in which the length in the diameter direction of the rotating shaft 21 is shortened. ing.

  The rectangular cutting portion 40 forms a corner at the outlet from the charging passage 39 into the container 30 and on the downstream side in the rotation direction of the rotary blade 21.

  The take-out port 41 is opened in the container 30 on the side where the rotary blade 27 rotates downward, that is, on the downstream side in the rotation direction of the rotary blade 27 with respect to the inlet 37, and the gap A between the upper surface of the strainer 23 and the inner surface of the container 30 is The inflow port 37 opens to the entire position smaller than the length B in the diameter direction of the rotating shaft 21 (circumferential direction of the container 30). A plurality of insertion ports 31 are opened at the lower edge of the outlet 41. The width of the outlet 41 is the same as the length in the container 30 cylinder direction.

  The lid body 42 is rotatably attached to the upper edge portion of the outlet 41 using a hinge 43, and the upper portion of the lid body 42 is pressed against the strainer 23 side by a pressurizing means 44 made of a spring or the like.

  The drain plug 45 includes a metal piece 46 and has a drain channel 47 that is open at a size that does not allow a hand to enter the central part. The drain channel 47 communicates the container 30 with the sink 38. . The drain plug switch 48 incorporates a magnet for detecting the metal piece 46 of the drain plug 45, and determines whether or not the drain plug 45 is attached to the inlet 37.

  The driving of the drive unit 22 is permitted when the drain plug 45 detects that the drain plug 45 has been inserted into the inlet 37. Moreover, a water level detection means (not shown) detects the water level of the container 30. A control unit (not shown) controls the drive unit 22.

  The operation of the solid-liquid separator configured as described above will be described.

  Before that, the basic operation of the solid-liquid separation process will be described. The rotating blades 27 shown in FIG. 1 are drawn with a thick solid line when they are stopped at a predetermined rotation angle, and are drawn with a two-dot chain line when they are slightly rotated from the stopped state. As illustrated by the solid line, the state where the free end of the rotary blade 27 protruding upward from the strainer 23 and positioned at the top is stopped between the input passage 39 and the outlet 41 is the best predetermined stop position. .

  After the user removes the drain plug 45 from the inlet 37, the garbage in the sink 30 is poured into the container 30 from the inlet 37, and the drain plug 45 is attached again, the solid-liquid separation process is automatically started. .

First, when the user removes the drain plug 45 and the garbage is poured into the container 30 through the inlet 37, the garbage is collected on the upper surface of the strainer 23 through the introduction passage 39. At that time, since the cross-sectional area of the input passage 39 is increased downward, the thrown-in garbage does not have a chance to touch the input passage 39 and the input passage 39 is not easily contaminated. On the other hand, when tap water or drainage is poured into the container 30 from the inlet 37, the tap water or drainage passes through the gap of the strainer 23 and is drained from the drain port 36.

  Thereafter, the drain plug 45 is inserted into the inflow port 37, and the drain plug switch 48 detects the metal piece 46 of the drain plug 45. As a result, it can be confirmed that the user has not accidentally pushed his / her hand into the inlet 37. In addition, when the drain plug switch 48 cannot detect the metal piece 46 of the drain plug 45, the control unit prohibits the driving of the driving unit 22, and thus the safety of the user can be ensured.

  Next, the water level detection means (not shown) does not detect a water level higher than a predetermined value, or the period during which tap water or drainage is not poured from the inlet 37 into the container 30 through the drainage channel 47 is measured. When a predetermined period (about 10 seconds to 5 minutes) corresponding to a period in which water droplets adhering to the dust pass through the gap of the strainer 23 by its own weight, the control unit (not shown) has stopped driving the driving unit 22 To start. In addition, when a water level detection means (not shown) detects the water level more than predetermined value within a predetermined period, a control part (not shown) does not start the drive part 22 which has stopped. Then, when the water level detection means next falls below the predetermined value, measurement of a period during which the water level above the predetermined value is not detected again is started.

  Next, the garbage transporting operation performed between steps D1 to D3 in FIG. 3 will be described in detail.

  The control unit (not shown) has a second period during which the drain plug detection unit 48 detects the presence of the drain plug 45 and the water level detection means (not shown) detects a water level below a predetermined value. When the predetermined period is reached, the driving of the driving unit 22 that has stopped is started. And the drive part 22 rotates the rotating shaft 21, and stops after rotating the rotating blade 27 for the 1st predetermined period (30 second-1 minute) at the rotational speed of about 10 rotations per minute, for example.

  At that time, since the fixing rod 33 penetrating the rail communication port 25 and the container communication port 32 restricts both ends of the rail 24 inserted into the insertion port 31 from coming off the container 30, the gap between the strainers 23 is reduced. The contact between the rail 24 and the rotary blade 27 can be reduced as much as possible, the load on the drive unit 22 that rotationally drives the rotary blade 27 can be reduced, and the friction between the rail 24 and the rotary blade 27 can be reduced.

  As shown in FIG. 1, the rotating blade 27 that has started rotating rotates counterclockwise, and the tip of the rotating blade 27 starts to protrude upward from the right side of the strainer 23 through the gap of the strainer 23, and Since it moves from right to left on the strainer 23 along with the rotational motion, the rotary blade 27 conveys the solid matter (garbage) so as to push along the upper surface of the strainer 23. At this time, the rotary blade 27 does not have the effect of lifting the solid material, and the liquid adhering to the solid material conveyed along the upper surface of the strainer 23 passes through the gap between the strainer 23 due to vibration and its own weight due to the conveyance. 36 is drained.

  The tip of the rotary blade 27 protruding from the strainer 23 tries to push out the solid matter that has moved to the outlet 41 from the outlet 41 to an external waste container (not shown). At that time, the lid 42 pressed against the strainer 23 side by the pressurizing means 44 such as a spring compresses the solid together with the rotary blades 27 that extrude the solid, and the liquid adhering to the solid (juice or tap water) Etc.) and the dehydrated liquid passes through the gaps of the strainer 23 and is discharged from the drain port 36.

Further, when the rotation of the rotary blade 27 is advanced, the crossing angle between the rotary blade 27 and the strainer 23 that has sunk in the gap of the strainer 23 near the outlet 41 becomes an acute angle. However, since the rail 24 is curved upward and the rotary blade 27 is curved so as to protrude in the rotational direction, the crossing angle is not an extremely acute angle, and an angle greater than a predetermined angle can be secured. When a solid object is sandwiched between the rotary blade 27 and the strainer 23, a vector sandwiched from the vertical direction and a vector that is pushed in the horizontal direction act on the solid substance. However, as the crossing angle (degree of curvature) increases, the horizontal direction increases. The vector becomes large, and the hard solid material slides on the upper surface of the strainer 23 and is pushed open to push the lid 42 out. That is, it is possible to prevent the solid matter from locking the rotary blade 27, and the solid matter can be smoothly discharged from the outlet 41 to the outside.

  Of course, most of the solids passing through the inflow port 37 are smaller than the length B of the inflow port 37 in the diameter direction of the rotation axis 21, and the length B of the inflow port 37 in the diameter direction of the rotation axis 21 is It is smaller than the gap A between the upper surface and the inner surface of the container 30. That is, since it is smaller than the gap A between the upper surface of the strainer 23 and the inner surface of the container 30, the solid material is conveyed while moving from the right to the left on the upper surface of the strainer 23 at the tip of the rotary blade 27 and is taken in the size as it is charged. It is discharged from the outlet 41.

  In these operations, since almost the entire rotating blade 27 (length 30 mm) protrudes from the gap of the strainer 23, a large solid material can be transported, so that the solid material is reduced before being introduced from the inlet 37. There is no need for crushing, and no crushing machine is required before the inlet 37. In addition, since the solid-liquid separation process is performed without crushing the solid matter, there is hardly any fine solid matter that passes through the gap between the strainers 23, so that the dry weight recovery rate can be increased to 90% or more. Can be prevented.

  Furthermore, since a large solid that has not been crushed is separated into solid and liquid, the gap between the strainers 23 can be widened by about 2 to 3 times compared to the conventional example, and the rotating blades 27 can be a thick flat plate. The number of blades 27 can be reduced, and the number of the blades 27 can be reduced, so that the assembly work of the apparatus can be facilitated and the assembly cost can be reduced. Further, since the gap between the lower surface of the strainer 23 and the lower part of the inner surface of the container 30 is wide, the opening area of the drain port 36 can be increased and the drainage performance can be enhanced.

  When the solid liquid charged into the container 30 from the inlet 37 is a large amount of solid that accumulates to the charging passage 39, the rotating blade 27 moves along the upper surface of the strainer 23 while moving through the gap of the strainer 23. Is cut and separated by the angular cutting part 40, the load on the driving part 22 can be reduced.

  Then, a part of the solid matter remaining in the charging passage 39 falls on the upper surface of the strainer 23, but the solid matter dropped by the other rotating blades 27 coming next is conveyed to the outlet 41 along the upper surface of the strainer 23. The solid matter is pushed out from the outlet 41. As a result, even when a large amount of solid matter is introduced into the container 30 from the inlet 37, the waste water containing the solid matter can be solid-liquid separated in a short time.

  If the drive unit 22 stops after driving the rotary shaft 21 for the first predetermined period, the control unit prohibits the drive unit 22 from being driven. That is, once the drain plug 45 is extracted from the inlet 37 and the drive unit 22 operates and stops for a predetermined time, the stopped state is maintained and the drain plug 45 is inserted into the inlet 37 again to detect the drain plug. Only when the part 48 redetects the metal piece 46 of the drain plug 45, the drive of the drive part 22 is permitted. That is, this solid-liquid separation device operates in accordance with the timing when waste water containing garbage is poured into the container 30, so that it can be operated with much less power consumption than in continuous operation, and the user can If you forget to do 45, useless power is not consumed.

Further, the rotary blade 27 that has discharged the solid matter from the outlet 41 and has passed through the gap between the strainers 23 immediately passes through the gap between the rail guide plates 26. As a result, the gap between the rotary blades 27 is maintained, so that the rotary blade 27 passes through the gap between the rail guide plates 26 and then the rail 2
4 enters the gap of the stray 23 again without colliding with the lower surface of 4.

  On the other hand, the rotary vane 27A in contact with both end faces of the strainer 23 has a gap between the rail 24A forming the both end faces of the strainer 23 and the rib portion 35, and a rail guide plate 26 integrally formed with the previous rail 24. And the gap between the rib portion 35 and the rib portion 35. As a result, the rotary blade 27A passes through the gap between the rail guide plate 26 and the rib portion 35 and then enters the gap between the rail 24A and the rib portion 35 again without colliding with the lower surface of the rail 24.

  As shown in FIG. 2, among the plurality of laminated rotating blades 27, the rotating blades 27A located on the outer side in the stacking direction are regulated by a rail 24A and a rail guide plate 26 on one surface, and the opposite surface is a rib. Since it is regulated by the portion 35, it rotates in a state regulated from both sides by the rail 24A, the rail guide plate 26 and the rib portion 35. For this reason, the rotating blade 27A hardly vibrates even if it rotates, so that it does not easily cause metal fatigue due to the rotating motion and is not easily deformed. Further, since the rotary blade 27A does not contact the entire end face of the container 30 and rotates in a state where the position is partially regulated by the rib portion 35, the frictional force applied to the rotary blade 27A is reduced and applied to the drive unit 22. The load can be reduced.

  When the solid liquid consisting of solid matter or drainage flows into the container 30 from the inlet 37, the strainer 23 is inclined upward toward the outlet 41, so that tap water and drainage cannot rise up the upper surface of the strainer 23. The water passes through the gap between the strainers 23 and is drained from the drain port 36.

  Furthermore, when a large amount of solid liquid flows into the container 30 from the inflow port 37, a large amount of tap water or drainage cannot pass through the gap of the strainer 23 at once, and a part thereof spreads on the upper surface of the strainer 23 toward the periphery, The tap water and drainage toward the take-out port 41 are weakened by the rotating blades 27 located at the top stopped at a predetermined angle, and the movement of the solid matter is blocked by the rotating blades 27 at the top. On the other hand, since the air pressure in the container 30 is increased by the momentum of the solid liquid to be added, the air pressure acts in the direction of pushing the lid 42 upward. However, the lid body 42 pressed by the pressurizing means 44 prevents the rise of the air pressure in the container 30 from pushing the lid body 42 open, so that tap water and drainage can be prevented from leaking from the outlet 41. The above-described effect can be sufficiently obtained even when the free end of the rotary blade 27 located at the top of the rotary blade 27 is displaced to the middle of the outlet 41.

  The solid substance thrown in from the inlet 37 is accumulated on the upper surface of the strainer 23 immediately below the inlet 23 toward the inlet 23, and the solid matter hardly accumulates in the periphery thereof, and both end portions of the cylindrical container 30 are accumulated. Nearly no solid matter accumulates in the vicinity. The solid matter accumulated on the upper surface of the strainer 23 obstructs the flow of tap water and drainage flowing into the container 30 from the inlet 37, but the solid matter deposited in the vicinity of both ends of the container 30 has a small accumulation amount. The tap water or drainage that has flowed into the passage 30 passes through the gap between the strainers 23 near both ends of the container 30 in a short time and is discharged from the drain outlet 36. That is, even if wastewater containing garbage collected in the sink 38 is poured at once, the wastewater can be solid-liquid separated in a short time and only the liquid can be discharged from the drainage port 36.

  The rail guide plate 26 is not necessarily formed integrally with the rail 24, and may be provided alone and inserted into the container 30 in the same manner as the rail 24, and the material cost for the space between the rail 24 and the rail guide plate 26 is sufficient. Can be reduced. The take-out port 41 is opened from a position where the gap A between the upper surface of the strainer 23 and the inner surface of the container 30 is larger than the length B of the inflow port 37 in the diameter direction of the rotary shaft 21 toward the downstream side in the rotation direction of the rotary blade 27. In short, the gap A between the upper surface of the stray 23 and the inner surface of the container 30 may be larger than the length B of the inflow port 37 in the diameter direction of the rotary shaft 21.

  Further, the water level detection means may be a water level sensor or a water amount sensor as long as it can determine whether tap water or drainage is being poured from the inlet 37 into the container 30 through the drainage channel 47.

  Although the above embodiment has been described in the case where the cross-sectional areas of the inlet 37 and the inlet passage 39 are circular, the cross-sectional areas of the inlet 37 and the inlet passage 39 may be rectangular, In that case, if the solid matter to be thrown is slender, it collides with the wall surface of the throwing passage 39 in the middle of dropping, and the length direction of the solid matter is aligned with the cylindrical direction of the container 30. It becomes easy to deposit on the upper surface of the strainer 23. Accordingly, the elongated solid is not cut by the square cutting portion 40, but is transferred to the take-out port 41 by the rotation of the rotary blade 27 and is discharged from the take-out port 41 as it is. The amount of solid matter can be suppressed, and deterioration of water quality can be prevented.

  As described above, since the solid-liquid separation device according to the present invention performs solid-liquid separation processing of the input solid matter as it is, it does not particularly require a solid material crusher, and is not limited to a household one, but also a hotel or factory. It can also be applied to kitchen facilities such as
