[0020] Embodiment

[0021] As Figure 1 shown, a high-efficiency solid-liquid separation device includes a coarse filtration system 1, a multi-stage filtration system and a fine filtration system 4;

[0022] The coarse filtration system 1 includes a coarse filtration container and a macroporous filtration grille 6. One side of the top surface of the coarse filtration container is provided with a feed inlet 5, and the macroporous filtration grille 6 is arranged inside the coarse filtration container. The other side of the bottom surface of the coarse filtration container is provided with a discharge port. The feed inlet 5 and the discharge port are respectively located on both sides of the macroporous filtration grille 6 to achieve preliminary separation of large-volume materials.

[0023] The multi-stage filtration system includes a filtration chamber body 2, a plurality of first baffle plates 7, a plurality of second baffle plates 8, a plurality of screws 10 and a plurality of discharge valves 11. The top surface of the filtration chamber body 2 is provided with a top cover plate 16 to inhibit the unorganized diffusion of materials, and at the same time facilitate inspection, maintenance and cleaning. The plurality of second baffle plates 8 are evenly arranged in the middle of the filtration chamber body 2, and the interior of the filtration chamber body 2 is divided into a plurality of overflow chambers 3. The plurality of first baffle plates 7 are respectively arranged in the middle of the plurality of overflow chambers 3, and an "S"-shaped overflow channel is formed in the filtration chamber body 2 through the first baffle plates 7 and the second baffle plates 8 to increase the flow path of materials in the chamber and at the same time provide guidance for the sedimentation process of sediments. The bottom of each overflow chamber 3 is provided with a funnel-shaped discharge pipeline. The screw 10 is arranged in the middle of the funnel section of the discharge pipeline, and the discharge valve 11 is arranged on the outlet section of the discharge pipeline. A viewing window 9 is also provided at the bottom of the side wall of each overflow chamber 3 to facilitate observing the position of the precipitated solids. The discharge port of the coarse filtration container is aligned with the top edge of the overflow chamber 3 on one side of the filtration chamber body 2.

[0024] The fine filtration system 4 includes a discharge pipeline 12, a discharge port 14 and a microporous filtration grille 15. The discharge port 14 is arranged on the upper part of the side wall of the overflow chamber 3 on the other side of the filtration chamber body 2. The discharge port 14 is externally connected to the discharge pipeline 12. The microporous filtration grille 15 is arranged at the connection between the discharge port 14 and the side wall of the overflow chamber 3 to perform fine separation of materials. An inclined downstream plate 13 is provided at the side wall of the overflow chamber 3 connected to the discharge port 14 to facilitate the coagulated fine materials after separation to flow downstream and return to the overflow chamber.

[0025] The working process of the present utility model:

[0026] When the utility model is in use, the waste materials to be separated are put into the coarse filtration container from the feed inlet 5. The waste materials are preliminarily separated through the large-hole filtration grille 6. After the preliminary filtration through the large-hole filtration grille 6, the large-volume solid materials remain in the coarse filtration container, and the small-volume solid materials and liquid materials flow into the overflow bin 3 from the discharge port of the coarse filtration container after coarse filtration. When an overflow bin 3 is full, the materials flow into the next overflow bin 3 along the "S"-shaped overflow channel, continuously replenish the materials into the filtration bin body 2, and regularly clean the large-volume solid materials remaining after separation in the coarse filtration container to keep the coarse filtration container unobstructed. Until the materials in the filtration bin body 2 are full and there is liquid material flowing out of the discharge pipe 12, adjust the feeding speed of the feed inlet 5 so that the clarity of the liquid material in the discharge pipe 12 meets the actual requirements, thereby achieving the balance between feeding and discharging. After the solid-liquid mixed materials in the filtration bin body 2 slowly pass through the multi-stage "S"-shaped overflow channel, the solid materials settle to the bottom. The position and quantity of the deposited materials can be observed in real time through the viewing window 9. When the deposited materials reach a certain amount after a period of filtration, suspend the feeding of materials from the feed inlet 5, discharge the liquid materials in the filtration bin body 2, then start the screw 10. The screw 10 rotates to break the deposited solid materials, and then open the discharge valve 11 to discharge the broken solid materials. After the solid materials are discharged, close the screw 10 and the discharge valve 11, and continue to feed materials from the feed inlet 5. Repeat the above steps. After multi-stage material separation, the liquid materials are finely separated through the small-hole filtration grille 15 and then flow into the discharge pipe 12 from the discharge port 14 and are discharged. The fine solid materials generated after filtration through the small-hole filtration grille 15 coagulate and fall on the downstream plate 13, flow downstream along the downstream plate 13, and return to the overflow bin for re-separation and filtration;

[0027] When a failure occurs in the overflow bin 3, open the top cover plate 16 on the filtration bin body 2, and the operators enter for inspection, repair and cleaning; the top cover plate 16 can also inhibit the unorganized diffusion of materials.

[0028] After the solid-liquid waste is filtered through processes such as coarse filtration, multi-stage separation filtration, and fine filtration, the solid and liquid materials are separated, continuous separation operation is achieved, the subsequent disposal and blockage clearing work is effectively reduced, and the material disposal efficiency is improved; personnel inspection and repair operations are avoided, and the labor cost and the safety risk of material spillage and leakage are reduced.
