Embodiments of the present invention will be described below in detail with reference to the drawings.

1 to 4 are views showing the configuration of a solid-liquid separation device according to an embodiment of the present invention. FIG. 1 is a sectional side view, and FIG. 2 is a view taken in the direction of arrow X in FIG. Main part sectional view, FIG.
Is a cross-sectional view of a main part as viewed from the direction indicated by the arrow Y with the top cover of FIG. 1 removed,
FIG. 4 is a side view as seen from the Z direction shown in FIG.

In the solid-liquid separation device 1 of the present embodiment, a driving pulley 3 and a driven pulley 4 extending between the inner walls of the container 2 are respectively arranged at the upper part on one side and the lower part on the other side in the container 2 having a substantially rectangular parallelepiped shape.
A plurality of endless elastic belts 5 are bridged between the two pulleys 3 and 4 over the entire width between the inner walls of the container 2 so that the upper inclined surfaces 6 of the plurality of elastic belts 5 move upward. It is configured to be rotationally driven by a driving unit 8 including a motor and the like connected to the shaft 7.

The driven pulley 4 disposed on the lower side is rotatably mounted on the shaft 9, and an inverted T-shaped inflow pipe 11 is mounted above the driven pulley 4 through an upper lid 10 that covers an upper opening of the container 2. Have been. The inflow pipe 11 has a drain pipe 1 from a disposer or the like attached below the sink of the sink.
2 are connected so that the solid-liquid mixture containing the crushed garbage and the like can be opened laterally.
It is configured to flow from 3, 13

Further, the upper inclined surface 6 of the plurality of elastic bands 5 and the inner wall of the container 2 form the inlet 13 of the inflow pipe 11.
The inflow part 14 of the solid-liquid mixture which flows in more is formed.

On one side wall of the container 2, the solid-liquid mixture flowing from the inlet 13 of the inflow pipe 11 is inclined upward from the upper inclined surface 6 of the plurality of elastic bands 5. Above the height position corresponding to the surface 6, ie, the drive pulley 3
The liquid discharge port 15 is formed so as to be deviated to the side and positioned substantially at the center of the upper inclined surface 6 in the height direction. The liquid discharge port 15 is provided with a discharge tube 16 extending downward, and is connected to a drainage pipe to a sewer or a wastewater treatment device.

Below the driving pulley 3, a partition wall 2 is provided.
b, a solid discharge port 17 and a discharge tube 18 are formed to discharge the solids falling over the drive pulley 3. The solids (organic substances) falling through the discharge tube 18 are composted by a microbial decomposition treatment system. (Composting) It is to be fed into equipment.

Each of the elastic belts 5 is made of rubber or the like and has a circular cross-sectional shape. In accordance with this, the driving pulley 3 and the driven pulley 4 have respective elastic belts as shown in FIGS. 5
The grooves 3a and 4a are formed so as to fit in and hold the elastic bands 5 at predetermined intervals. This makes it possible to drive each elastic band 5 at a predetermined interval. Spacing between grooves 3a of drive pulley 3 and grooves 4a of driven pulley 4
The space between the elastic bands 5 is formed such that the elastic bands 5 are driven in parallel with a gap (slit) S smaller than the width of the elastic band 5. Thereby, the separation accuracy of the solid-liquid mixture can be improved.

As shown in an enlarged view in FIG. 2 (b), a partition wall 2b located below the driving pulley 3 has solid components adhering between the elastic bands 5 and the grooves 3a of the driving pulley 3. In order to scrape off, a scraper 20 having a tip portion formed in a corresponding shape is attached. As shown in an enlarged view in FIG. 2C, the side wall 2a of the container 2 adjacent to the elastic band 5 located on both sides is formed so as to protrude inward in order to reduce a gap between them. I have.

Since the elastic band 5 is formed to have a circular cross section, the driven pulley 4 side also has an uneven shape as shown in an enlarged view in FIG. The concave and convex plate 21 conforming to the above shape is attached so as to reduce the size.

On the other hand, below the upper inclined surface 6, the elastic band 5 turned downward is divided into three pulleys 22, 23, 2 without grooves.
A tension adjusting unit 25 that adjusts the tension (tensile force) of the elastic band 5 by bending the elastic band 5 is provided. Of the three pulleys 22 to 24, pulleys 2 on both sides
The shafts 26 and 28 are fixed to the shafts 2 and 24. The positions of the shafts 27 and 28 can be adjusted by moving the shaft 27 of the middle pulley 23 between a plurality of shaft holes 29 provided at equal intervals. Can be adjusted appropriately. This eliminates the problem of slippage,
The moving speed of each elastic band 5 can be kept constant.

In the above construction, a solid-liquid mixture such as waste water containing garbage pulverized by the disposer flows in through the inlets 13 on both sides of the inflow pipe 11, and a slit S is provided between the elastic bands 5. Flows down on the upper inclined surface 6 on which is formed. At this time, first, the water accumulates in the inflow portion 14 formed by the upper inclined surface 6 of the elastic band 5 and the inner wall of the container 2, and the water level rises. By driving the upper inclined surface 6 of the elastic band 5 upward, a new slit S without clogging is fed out, so that the liquid passes smoothly.
The solid-liquid mixture can be continuously separated by filtration.

Therefore, with a relatively simple structure, it is possible to separate relatively small particulate solids contained in the disposer pulverized wastewater or the like, and it is possible to treat a large amount of solid-liquid mixture for a long time without clogging. . Also,
The plurality of elastic bands 5 are arranged substantially diagonally to the container 2 when viewed from the side, so that the container 2
Can be downsized, so that the device can be downsized,
It can also be installed under the sink sink.

The total width of the slits S formed between the plurality of elastic bands 5 and the moving speed of the elastic bands are appropriately set in accordance with the amount of the solid-liquid mixture flowing from the inlet 13. By doing so, a structure that can withstand the inflow amount of the inflowing solid-liquid mixture, that is, a stable operation can be performed without the inflowing solid-liquid mixture overflowing from the container 2.

On the other hand, solids such as pulverized food waste move on the upper inclined surface 6 on the elastic band 5 and move upward. The solid that has moved upward falls below the drive pulley 3 and falls downward. At this time, the solids adhering to the driving pulley 3 are scraped off by the scraper 20, so that the amount of solids mixed with the liquid when the elastic band 5 moves to the driven pulley 4 side can be reduced.

In the present embodiment, the liquid discharge port 15 is formed at the above-described position on the side surface of the container 2 and the liquid discharge port 15 is formed.
Since the liquid can be stored up to the lower water level, the flow of the liquid from the inflow port 13 can be suppressed by the liquid itself. Therefore, the solid-liquid mixture that flows in directly hits the elastic bands 5 to widen the mesh width between the elastic bands 5 and prevent a problem that a solid mixes with a liquid and flows out. Even with the above configuration, if there is a continuous inflow from the inflow port 13, the liquid stored up to the lower water level of the liquid discharge port 15 is sequentially replaced, so that the liquid stays and odors are generated. There will be no problems such as unsanitation.

Further, in the present embodiment, the inflow pipe 11 is formed in an inverted T shape so that the inflowing solid-liquid mixture flows down from the inflow ports 13 on both sides in the lateral direction. Is weakened by the inverted T-shaped inflow pipe 11, so that the above-described effects can be further enhanced.

The inclination angle θ of the upper inclined surface 6 shown in FIG. 1 is desirably set within a range of 10 degrees to 60 degrees. That is, when the inclination angle is smaller than 10 degrees,
As a result, the length of the apparatus itself becomes longer, which is disadvantageous for miniaturization. If the angle exceeds 60 degrees, the solids on the upper inclined surface 6 slide down and cannot be transported upward.

The difference from the above embodiment is that in the above embodiment, the liquid outlet 15 is formed on the side surface of the container 2, but in the present embodiment, the liquid outlet 30 is formed on the bottom surface of the container 2.
A discharge cylinder 31 is provided directly downward.

As a result, even if the inflow from the inflow port 13 is not continued, the wastewater does not stay in the container 2, so that there is no problem such as generation of offensive odor and unsanitation. .

FIG. 9 is a view showing the configuration of a main part of still another embodiment of the present invention, wherein the same reference numerals as those of the above-mentioned embodiment indicate the same or corresponding parts.

In this embodiment, the groove 3a formed in the drive pulley 3 in the above embodiment is formed deeper than the diameter of the elastic band 5, and a blade 3b projecting from the elastic band 5 is formed between the grooves 3a. It is configured to be formed.

With this configuration, the solids clogged in the slits S between the elastic bands 5 moving toward the drive pulley 3 can be lifted by the blades 3b so as to be lifted. By scraping and dropping the solids floating on the scraper 20, the slit S
Solid matter clogged can be removed cleanly. In this case, the tip of the scraper 20 may be linear.

In the above embodiments, the elastic band 5 has a circular cross section. However, the cross section may have an inverted trapezoidal shape or an inverted triangular shape. In this case, the tip of the scraper 20 has a straight line shape. Even solids can be easily scraped of solids.

To form a loop as shown.

Each elastic band 5 bridged over these pulleys causes the upper inclined surface 6 to move from obliquely downward to obliquely upward by the rotation of the driving pulley 3 in the direction of the arrow, as in the previous embodiment. Since each elastic band 5 is guided by a grooved pulley, it has a gap (slit S) at a predetermined interval.

In this embodiment, each elastic band 5
Has an inverted trapezoidal cross-section made of rubber or the like that does not contain a core material.
(0%). This eliminates the need for the tension adjusting unit 25 that adjusts the tension as in the above-described embodiment.

Further, in the present embodiment, a gutter 50 is provided in a space formed on the bottom side of the container 2 surrounded by the elastic band 5 having the loop shape described above. The gutter 50 collects the liquid passing through the upper inclined surface 6 of the elastic band 5 and discharges the liquid in the lateral direction of the container 2.

On the inner side of the upper edge of the gutter 50 located on the lower driven pulley 4 side, water and a small amount of solids flowing down the elastic band 5 of the upper inclined surface 6 are intercepted and discharged into the gutter 50. Brush type weir 51 is attached. Since the portion in contact with the elastic band 5 is formed by a brush,
Water and a small amount of solids flowing down the elastic band 5 can be taken into the gutter 50 without damaging the elastic band 5.

As shown in FIG. 15, the gutter 50 is provided with a liquid component passing through the slit S of the elastic band 5.
A downward slope is set toward the discharge port 52 so as not to stay inside. This gradient is generally set to 1/100 or more necessary for the liquid component to flow naturally.

Further, in order to prevent water or solid matter adhering to the elastic band 5 or the like from accumulating on the bottom of the container 2, a discharge port 30 and a discharge port extending downward from the discharge port 30 are provided at the bottom of the container 2. A tube 31 is provided.
Are connected to a discharge tube 53 attached to the discharge port 52 of the.

Further, water and solids which are inclined downward from the lower side of the upper driven pulley 40 toward the upper edge of the gutter 50 and removed by a rotating brush for scraping the back surface and a brush for cleaning the groove portion, which will be described later, are used for the gutter 50. There is provided a discharge inclined plate 54 for discharging the liquid.

Further, below the inflow port 13 into which the solid-liquid mixture flows, there is provided an inflow inclined plate 60 for preventing the pressure caused by the falling of the flowing solid-liquid mixture from directly acting on the elastic band 5. Have been. This inflow inclined plate 60 is
Is attached to the side wall by a hinge (not shown),
The tip end reaching above the gutter 50 is configured to be rotatable up and down. Accordingly, when solid matter is attached to the upper inclined surface 6 of the elastic band 5 from the lower driven pulley 4 side and adhered to the surface of the elastic band 5, as shown by a two-dot broken line, When the solid-liquid mixture flows in from the inflow port 13, the gap is closed as indicated by the solid line due to the pressure and the weight of the solid-liquid mixture. The solid-liquid mixture is configured so as not to flow out to the lower driven pulley 4 side and to cause a problem that solid matter is deposited in the groove 4a. The inflow inclined plate 60 may be urged toward the elastic band 5 by a spring or the like.

On the back side of the elastic band 5 near the center of the upper inclined surface 6, a predetermined gap (slit width) between the elastic bands 5 due to the flow velocity, pressure, etc. generated when the solid-liquid mixture flows. In order to prevent a change in the diameter, a rotary pulley 61 for preventing openings is disposed having a groove shape similar to the cross-sectional shape (here, an inverted trapezoidal shape) of the elastic band 5. The rotating pulley 61 has a shaft 62 connected to a shaft 7 of the driving pulley 3 rotated and driven by the driving unit 8 via a toothed pulley 62a and a toothed belt 62b. They are driven to rotate at the same speed. The depth of the groove 61a of the rotary pulley 61 is set to be equal to or less than the thickness of the elastic band 5, so that the protruding portion between the grooves 61a is exposed on the surface of the elastic band 5 and solid matter is caught. It is configured so that no serious inconvenience occurs.

A back surface scraping rotary brush 71 is disposed between the opening preventing rotary pulley 61 and the upper driven pulley 40 so as to be in contact with the back surface of the elastic band 5. Note that a rotating roller other than a brush, such as a sponge or a cloth, may be used. The rotating brush 71 for scraping the back surface
The shaft 72 is connected to the shaft 7 of the driving pulley 3 rotated by the driving unit 8 via a toothed belt 72b crossing a toothed pulley 72a, and the rotation direction is It is set to be opposite to the direction,
It is preferable that the rotation speed is set to be 1 to 5 times the peripheral speed of the elastic band 5. Further, a scraper 73 for removing solid matter and water attached to the back surface scraping rotary brush 71 is provided.

Further, the groove 40a of the upper driven pulley 40
A groove cleaning brush 74 for removing solid matter adhered to the surface is provided.

The elastic band 5 passes through the upper driven pulley 40 and changes the traveling direction substantially vertically downward toward the driving pulley 3 disposed therebelow to convey the solid material.
During the transport, the solid is dropped by its own weight in the direction of the discharge port 17. The angle formed by the elastic belt 5 between the upper driven pulley 40 and the driving pulley 3 with the horizontal line is preferably set to 90 to 120 ° so that the separated solid matter easily falls.

Further, a rotary brush 81 for forcibly scraping and removing solid matter attached to the elastic band 5 is disposed at a position where the traveling direction of the elastic band 5 is largely changed by the driving pulley 3 disposed below. Have been. The scraping rotary brush 81 presses the brush portion against the elastic band 5 to scrape off solid matter attached to the elastic band 5. The rotary brush 81 is disposed beside the drive pulley 3 so as to scrape it below the discharge port 17, and its shaft 82 is connected to the drive unit 8.
The pulley 82a and the toothed belt 82b are connected to the shaft 7 of the driving pulley 3 which is driven to rotate.
The elastic belt 5 is set to be rotationally driven in a direction opposite to the traveling direction, and its rotation speed is set to be 1 to 10 times the peripheral speed of the moving speed of the elastic belt 5. Is preferred. Note that, instead of a brush, a sponge, cloth, or the like may be used to scrape the elastic belt 5 by pressing it.

In the above configuration, the solid-liquid mixture flowing from the inlet 13 hits the inflow inclined plate 60, and the flow velocity and the water pressure are reduced. Thereby, the inflow of the solid-liquid mixture directly hits the elastic band 5 to widen the mesh width between the elastic bands 5 and prevent a problem that the solid is mixed with the liquid and flows out. Recovery rate can be improved. In addition, the inflow inclined plate 60 prevents the solid-liquid mixture from flowing down the elastic belt 5 and obliquely downward, that is, to the lower driven pulley 4 side. Elastic band 5
A small amount of the solid-liquid mixture flowing down along the gap and the back surface between the two is stopped by the brush type weir 51 and flows out to the gutter 50.

The rotation preventing pulley 61 for opening the opening is provided with an elastic band 5 by the flow velocity, pressure, and the like generated when the solid-liquid mixture flows.
The gap between them (slit width) is prevented from changing,
Thereby, the recovery rate of the solid can be further improved. Further, since the liquid component is discharged to the gutter 50 through the slit S, the separated liquid component can be discharged efficiently without staying in the container 2.

The solid separated on the upper inclined surface 6 is conveyed obliquely upward by the elastic band 5. A small amount of the solid-liquid mixture adhering to the back side of the elastic band 5 is scraped off by the back surface scraping rotary brush 71 and falls on the discharge inclined plate 54. Since the discharge inclined plate 54 is installed inclined toward the gutter 50, the scraped solid-liquid mixture flows out into the gutter 50 by its own weight.

The solid-liquid mixture that could not be removed by the back surface scraping rotary brush 71 adheres to the groove 40a of the upper driven pulley 41 obliquely above it, but the groove is cleaned by one rotation of the pulley 41. It is removed by the brush 74, falls on the discharge inclined plate 54, and flows out to the gutter 50 by its own weight.

The solid matter remaining on the upper inclined surface 6 decreases in moisture while being conveyed by the elastic band 5. Then, after passing through the upper driven pulley 40, the solid material is separated from the elastic band 5 by its own weight and falls to the solid discharge port 17 while being conveyed substantially vertically downward.

The solid material which does not fall by its own weight is
A portion where the traveling direction of the elastic band 5 is largely changed at the portion and the surface is easily cracked due to cracks is forcibly scraped off by the scraping rotary brush 81 and removed. The rotating brush 81 is strongly pressed against the elastic band 5 so that the belly, not the tip, hits the elastic band 5. It is effective to increase the contact distance between the elastic band 5 and the rotating brush 81. The scraped solids are
Since the brush that has been pressed is returned to the original position and is blown below the solid discharge port 17, solid matter is less likely to adhere to the rotating brush 81 and the inner wall of the container 2.

As described above, according to the present embodiment, the recovery rate of the solids is improved, and the accumulation of the solids on the grooves 40a, 4a of the upper driven pulley 40 and the lower driven pulley 4 is prevented. As a result, a solid-liquid separation device requiring no long-term maintenance can be realized, and the life of the device can be improved.

As shown in FIG. 16, the elastic band 5 and each pulley and the discharge inclined plate (not shown) are sandwiched between both side plates 2c to form a unit, which is detachable inside the container 2 so that the unit can be removed during maintenance. It can be taken out of the container 2 in one piece. Also, a rotating brush 81 for scraping solids from the elastic band 5, a rotating pulley 61 for preventing openings,
By making the back surface scraping rotary brush 71 and the like detachable independently, even when the container 2 of the solid-liquid separation device 1 is fixed, maintenance can be easily performed by the above method.

It is also effective to form a flow path indicated by an arrow such that the liquid separated by the slit S of the inclined surface 6 is washed off over the return-side elastic band 5 passing below. in this case,
In order to prevent the solid-liquid mixture from splashing on the adjacent lower driven pulley 4, a brush-equipped partition plate 56 with
To be installed. The use of the brush 55 at the upper and lower portions in contact with the elastic band 5 is effective in that the elastic band 5 is not damaged.

In FIG. 21, the gutter 50 is eliminated, and all the liquid separated by the slit S of the upper inclined surface 6 is flushed to the lower elastic band 5 on the return side.
Instead of omitting the gutter 50, a part of the liquid separated by the slit S of the upper inclined surface 6 may be washed away by flowing to the return-side elastic band 5 passing below.

If the solid matter adhered to the elastic band 5 cannot be removed and is conveyed to the inflow section 14, the inflow inclined plate 6
At 0, there is a danger that solids will be blocked and deposited, but as described above, the inflow inclined plate 60 is made movable up and down, so that the inflow inclined plate 60 moves together with the movement of the elastic band 5 to which the solids adhere. Since the gap is formed by automatically turning upward as shown by the two-dot broken line, the solid matter attached to the elastic band 5 can be transported upward without being deposited.

FIG. 22 is a side sectional view showing a main part of still another embodiment of the present invention, and the same reference numerals as those of the above-mentioned embodiment indicate the same or corresponding parts.

Due to the installation conditions of the apparatus, the inflow pipe 11

Provision of 3 is also effective. In this way, by providing the weir 63 for temporarily storing the inflowing solid-liquid mixture, the collected solid-liquid mixture acts as a cushion, so that the pressure, flow rate, and the like due to the drop of the solid-liquid mixture can be further reduced. . Further, a gap 63a is formed between the lower part of the weir 63 and the elastic band 5 so that the accumulated solid-liquid mixture flows out as the elastic band 5 moves diagonally upward. The solid-liquid mixture flowing into the elastic band 5 is averaged and flows out onto the upper inclined surface 6 of the elastic band 5, so that the solid-liquid separation action can be made uniform.

Further, by providing a baffle plate 64 which is attached to the weir 63 and whose inclination direction is set to be opposite to that of the inflow inclined plate 60, the effect of the baffle plate 64 itself and the inflow inclined plate 60 and the weir 63 are provided. Of the elastic band 5

FIG. 23 is a view showing the configuration and operation of a main part of still another embodiment of the present invention, and the same reference numerals as those of the above-mentioned embodiment indicate the same or corresponding parts.

In order to drop the separated solid by its own weight, it is effective to deposit the solid on the elastic band 5 thickly. For this purpose, as shown in FIG. 23, a projecting portion 63 projecting downward is provided at the center of the weir 63 provided at the inflow portion 14.
It is preferable to form b so that the gap 63c with the elastic band 5 is made half or less of the gap 63a on both sides. When the solid-liquid mixture flows, the flow rate of the solid-liquid mixture passing through the gaps 63a on both sides increases as shown in FIG.
And gather at the center of the elastic band 5. That is, when the gap with the elastic band 5 is the same, both sides are in contact with the side walls 2a of the container 2, so that the flow is slow and the center is fast, so that the solid-liquid mixture tends to accumulate thickly on both sides. Therefore, by forming the protruding portion 63b and narrowing the gap 63c at the central portion, it acts to slow down the flow at the central portion, so that the solid-liquid mixture becomes thicker at the central portion. In this state, when water flows out of the slit S, the solids are thickly deposited at the center and easily fall by their own weight.

As a configuration for preventing solid matter from being caught between the elastic band 5 at both ends and the container side wall 2a, FIG.
As shown in FIG. 3A, a groove 2d corresponding to the cross-sectional shape of the elastic band 5 is formed in the container side wall 2a, and the elastic band 5 at both ends can be guided by the groove 2d.

When the present apparatus is used, as shown in FIG. 24, the discharge cylinder 1 extending downward from the solid discharge port 17 is used.
8 、 Solid volume reduction device (compost type or dry type) 100
Also, there is an advantage that a solid matter recovery device or the like can be attached, and the device to be attached is not selected.

The operation of the apparatus is started simultaneously with the operation of the disposer and, if a relay pump tank is interposed, the pump for pumping, etc., and after the inflow of the solid-liquid mixture is completed, the elastic band 5 is activated. It is preferable to stop after moving the loop one or more times. By driving like this,
Since the solid matter attached to the elastic band 5 is removed, it is possible to prevent the solid matter from becoming difficult to remove over time with the solid matter attached.

In order to prevent sticking of the movable portion of the apparatus due to drying or freezing, it is effective to periodically perform idle operation without stopping for a long time. To prevent freezing, it is also effective to incorporate a heater.

FIG. 25 is a side sectional view showing still another embodiment of the present invention, and the same reference numerals as those of the above-mentioned embodiment indicate the same or corresponding parts.

In the above embodiment, since the partition wall 2b is high, the pulleys 42 and 43 are required. However, as shown in FIG. 25, by making the partition wall 2b low, the loop shape of the elastic band 5 can be substantially a right triangle. Since the pulleys 42 and 43 of the above embodiment can be omitted, the configuration can be simplified, and operational effects such as easy maintenance and low cost can be obtained. Also in this case, similarly to the above embodiment, the angle θ formed by the elastic band 5 between the upper driven pulley 40 and the driving pulley 3 with the horizontal line is set to 90 to 120 ° so that the separated solid matter easily falls. Is preferred.

As described above, according to the present invention, the pulleys extending between the inner walls of the container are arranged at the upper portion on one side and the lower portion on the other side of the container, and the endless elastic band is provided between the pulleys to form the entire width between the inner walls of the container. The plurality of elastic bands are driven so that the upper inclined surfaces of the elastic bands move upward, so that a solid-liquid mixture of a solid and a liquid flows in above the plurality of elastic bands. By forming an inlet and forming a liquid outlet for discharging liquid separated by the plurality of elastic bands and a solid outlet for discharging solids, a relatively simple configuration is included in the disposer crushed drainage and the like. Relatively large solid-liquid mixtures can be processed over a long period of time without clogging. In addition, since the plurality of elastic bands are arranged substantially diagonally on the container, the container can be reduced in size with respect to the solid-liquid separation processing area. It can be installed.

Further, the plurality of elastic bands are arranged in parallel with a gap smaller than the width of each elastic band, and are driven at substantially the same speed to improve the separation accuracy of the solid-liquid mixture. Can be improved.

The upper inclined surface of the plurality of elastic bands and the inner wall of the container form an inflow portion of the solid-liquid mixture flowing from the inlet, and the inclined surface lower than the upper inclined surface of the plurality of elastic bands. On the side, by forming the liquid outlet so that the solid-liquid mixture flowing from the inlet is located above the height position corresponding to the upper inclined surface, the liquid can be stored up to the lower water level of the liquid outlet. Therefore, the force of inflow from the inflow port can be suppressed by the liquid itself. Therefore, the solid-liquid mixture that flows in directly hits the elastic bands, so that the mesh width between the elastic bands can be widened and a problem that solids are mixed with the liquid and flow out can be prevented.

On the other hand, the upper inclined surface of the plurality of elastic bands and the inner wall of the container form an inflow portion for the solid-liquid mixture flowing from the inflow port, and a liquid outlet is formed on the bottom surface side of the container, so that the flow is reduced. Even if the inflow from the entrance is not continuous,
Since the wastewater does not stay in the container, there is no problem such as generation of offensive odor and unsanitary condition.

Furthermore, the provision of the adjusting means for adjusting the tension of the elastic band eliminates the problem of slipping, and makes it possible to keep the moving speed of each elastic band constant.

On the other hand, by applying a certain amount of tension to the elastic band and bridging it between the pulleys, the above-mentioned adjusting means for adjusting the tension of the elastic band becomes unnecessary.

By setting the inclination angle of the upper inclined surface of the plurality of elastic bands to be in the range of 10 degrees to 60 degrees, the size of the solid-liquid separation device can be reduced, and the solid-liquid separation device can be made stable. Solid-liquid separation can be performed.

[0111] The total width of the slits formed between the plurality of elastic bands and the moving speed of the elastic bands are set in accordance with the amount of the solid-liquid mixture flowing from the inflow port, so that the mixture flows. A stable operation is possible without the solid-liquid mixture overflowing from the container.

Furthermore, between the pulleys on the upper inclined surface,
By providing a mechanism for preventing a predetermined interval between the elastic bands from changing, the solid matter recovery rate is improved.

Further, by providing a mechanism for removing solids and liquids attached to the back side of each elastic band, it is possible to prevent solids from being deposited on the grooves of the pulleys, so that it can be completed in a short time. Maintenance such as cleaning is not required, and the life of the apparatus is improved.

Further, by providing a mechanism for reducing the pressure, flow rate, and the like of the solid-liquid mixture flowing from the inflow port, the recovery rate of solids is further improved.

Further, by making the elastic band and the pulley over which the elastic band is bridged unitized and detachably mounted in the container, maintenance becomes easy.

Further, a gutter is provided in the space surrounded by the elastic band to receive and discharge the liquid passing through the upper inclined surface of the elastic band, so that the separated liquid stays in the container. It can be efficiently discharged without the need.

On the other hand, by adopting a configuration in which the solids adhering to the return elastic band are washed away by the liquid passing through the upper inclined surface of the elastic band, even fine solids adhering to the elastic band are removed. become able to.

Further, a mechanism for removing solids attached to the elastic band is provided on the solid discharge port side,
The solids recovery rate can be further improved.
