[0029] like Figure 1-Figure 8As shown, a solid-liquid separation device for environmental engineering comprises a base 1, on which a connecting separation box 2 and a filtrate box 6 are fixedly mounted, a liquid outlet pipe 10 is fixedly mounted on the lower surface of one end of the separation box 2, a filter cartridge 8 is rotatably mounted in the separation box 2, a traction unit for driving the filter cartridge 8 to rotate is fixedly mounted in the separation box 2, a feed hopper 7 connected to the inside of the filter cartridge 8 is fixedly mounted on the side of the separation box 2, a discharge unit is fixedly mounted in both the separation box 2 and the filtrate box 6, a filter screen 9 is fixedly mounted in the filtrate box 6, a connecting discharge pipe 14 is fixedly mounted on the side of the filtrate box 6, the discharge unit is slidably connected to the inner surface of the filter cartridge 8 and the upper surface of the filter screen 9, a cutting unit for cutting solid materials is fixedly mounted in the feed hopper 7, the liquid outlet pipe 10 is connected to the bottom of the filter cartridge 8 and the filter screen 9, an external feeding device transports the mixed material to be separated into the filter cartridge 8 through the feed hopper 7, and the solid materials in the mixed material are cut by the cutting unit. Reducing the size of the solid material is convenient for better separation of the liquid in the solid material. After the material enters the filter cartridge 8, the solid-liquid separation is carried out through the filter cartridge 8. The solid material is left on the filter cartridge 8. The filter cartridge 8 is driven to rotate by the traction unit. The separated solid material is turned over by the rotation of the filter cartridge 8 and the discharging unit, so that the liquid carried by the solid material can flow out better, thereby improving the efficiency of solid-liquid separation. The solid material separated by the filter cartridge 8 is pushed by the discharging unit to avoid the accumulation of the separated solid material on the filter cartridge 8 and affecting the efficiency of solid-liquid separation. The separated solid material moves to the filter screen 9 in the filtrate box 6. During the movement, the moisture in the solid material is separated again through the filter screen 9. The separated solid material is transported to the discharging pipe 14 for export and collection through the discharging unit. At the same time, the separated liquid in the filtrate box 6 flows into the separation box 2, and the separated liquid material in the separation box 2 is exported through the liquid outlet pipe 10.

[0030] like Figure 2-Figure 5As shown, the discharging unit includes a variable pitch spiral blade 403, and a driving assembly is fixedly installed in the separation box 2 and the filtrate box 6. The variable pitch spiral blade 403 is fixedly installed on the driving assembly. The variable pitch spiral blade 403 is slidably connected to the filter cartridge 8 and the filter screen 9. The blade pitch of the variable pitch spiral blade 403 gradually decreases. The variable pitch spiral blade 403 is driven to rotate by the driving assembly. The solid material separated from the filter cartridge 8 is flipped and pushed by the variable pitch spiral blade 403. When flipping, the liquid in the solid material is better separated. At the same time, the solid material separated in the filter cartridge 8 is transported to the filter screen 9 by the variable pitch spiral blade 403. 3 gradually decreases, and the variable pitch spiral blades 403 squeeze the solid material during the conveying process of the separated solid material, so that the liquid in the solid material is separated, and the separated liquid material flows out through the filter screen 9, and the squeezed solid material is conveyed to the discharge pipe 14 for extraction and collection by the variable pitch spiral blades 403. The variable pitch spiral blades 403 can not only extract the solid material separated on the filter cartridge 8 during the solid-liquid separation process to avoid the accumulation of the separated solid material affecting the separation efficiency of the filter cartridge 8, but also can squeeze the separated solid material again to reduce the amount of liquid in the solid material, and effectively improve the solid-liquid separation effect.

[0031] like Figure 1 , Figure 2 , Figure 7 As shown, the separation box 2, the filter cartridge 8, the filtrate box 6 and the filter screen 9 are all arranged at an angle. Through the inclined arrangement, the liquid on the filter cartridge 8 and the filter screen 9 can better shed the solid material, reducing the amount of liquid driven when removing the solid material, and guiding the separated liquid in the separation box 2 and the filtrate box 6 so that the separated liquid can better enter the liquid outlet pipe 10.

[0032] like Figure 1-Figure 5 As shown, the driving assembly includes a second motor 401 and a main shaft 402. The second motor 401 is fixedly installed on the side of the separation box 2. The main shaft 402 is rotatably connected to the separation box 2 and the discharge pipe 14. The part of the main shaft 402 located in the separation box 2 and the filtrate box 6 is fixedly connected to the variable pitch spiral blade 403. The main shaft 402 is fixedly connected to the output shaft of the second motor 401. The main shaft 402 is driven to rotate by the second motor 401, and the variable pitch spiral blade 403 is driven to rotate by the main shaft 402, so that the variable pitch spiral blade 403 pushes the material separated from the filter cartridge 8 and the filter screen 9.

[0033] like Figure 1 , Figure 3-Figure 8As shown, the traction unit includes a first motor 301, a gear 302 and a ring gear 303. The first motor 301 is fixedly mounted on both sides of the separation box 2. The output shaft of the first motor 301 is rotatably connected to the separation box 2. The gear 302 is fixedly mounted on the output shaft of the first motor 301. The ring gear 303 is fixedly mounted on the outer surfaces of both ends of the filter cartridge 8. The ring gear 303 is meshed and connected to the gear 302. The gear 302 is driven to rotate by the first motor 301. The gear 302 drives the filter cartridge 8 to rotate through the ring gear 303, so that the filter cartridge 8 can flip the solid material that needs to be separated, so as to better separate the liquid in the solid material.

[0034] like Figure 1 , Figure 8 As shown, the cutting unit includes a third motor 501 and a cutting roller 502. The third motor 501 is fixedly installed on the side of the feed hopper 7, and the cutting roller 502 is rotatably installed in the feed hopper 7. The cutting roller 502 is fixedly connected to the output shaft of the third motor 501. During the separation of solid and liquid materials, the cutting roller 502 is driven to rotate by the third motor 501, and the solid materials to be separated in the mixed material are cut by the cutting roller 502 to reduce the size of the solid materials, so that the liquid materials in the solid materials can be better separated, thereby improving the separation efficiency.

[0035] like Figure 2 , Figure 4 As shown, a placement rack 11 is fixedly installed on the inner upper surface of the separation box 2, and two spray pipes 12 are fixedly installed on the placement rack 11. The two spray pipes 12 are located above the filter cartridge 8, and the spray pipes 12 are connected to an external water supply device. When performing solid-liquid separation, the external water supply device transports water to the spray pipes 12 and sprays water through the spray pipes 12. The water sprayed from the spray pipes 12 flushes the filter cartridge 8, so that the debris in the filter holes on the filter cartridge 8 falls off, completing the cleaning of the filter cartridge 8, thereby preventing the debris from adhering to the filter cartridge 8 during the solid-liquid separation process and affecting the efficiency of the filter cartridge 8 in separating solid and liquid materials.

[0036] like Figure 2 , Figure 4 As shown, a roller 13 is rotatably installed on the placement frame 11, and the roller 13 is located between two spray pipes 12. The roller 13 is slidably connected to the outer surface of the filter cartridge 8. During the rotation of the filter cartridge 8, the filter cartridge 8 is squeezed by the roller 13, so that the filter cartridge 8 produces a certain deformation, which is convenient for the spray pipe 12 to better flush the filter cartridge 8, so that the debris blocked in the filter holes on the filter cartridge 8 falls off faster, thereby improving the cleaning effect of the filter cartridge 8.

[0037] Working principle: Figure 1 , Figure 2 , Figure 7 , Figure 8As shown, the external feeding device conveys the material to be separated into the filter cartridge 8 through the feeding hopper 7. During the feeding process, the cutting roller 502 is driven to rotate by the third motor 501, and the solid material to be separated is cut by the cutting roller 502;

[0038] like Figure 1 , Figure 3-Figure 8 As shown, after the mixed material to be separated enters the filter cartridge 8, the solid materials in the mixed material are separated by the filter cartridge 8, and the solid materials are left in the filter cartridge 8. At the same time, the first motor 301 drives the gear 302 to rotate, and the gear 302 drives the filter cartridge 8 to rotate through the gear ring 303, and the separated solid materials are turned over by the filter cartridge 8, so that the liquid in the solid materials can flow out better;

[0039] At the same time, if Figure 1-Figure 5 As shown, the second motor 401 drives the main shaft 402 to rotate, and the main shaft 402 drives the variable pitch spiral blade 403 to rotate, and the variable pitch spiral blade 403 pushes the solid material separated from the filter cartridge 8, so that the liquid in the solid material can flow out better during the movement;

[0040] like Figure 2-Figure 5 As shown, the solid material separated in the filter cartridge 8 is transported to the filter screen 9 by the variable pitch spiral blades 403. As the pitch of the variable pitch spiral blades 403 gradually decreases, the variable pitch spiral blades 403 squeeze the solid material during the process of conveying the separated solid material, so that the liquid in the solid material is separated, and the separated liquid material flows out through the filter screen 9. The squeezed solid material is transported to the discharge pipe 14 by the variable pitch spiral blades 403 for extraction and collection.

[0041] like Figure 2 , Figure 3 As shown, the liquid separated in the filtrate box 6 flows into the separation box 2, and the liquid material separated in the separation box 2 is discharged through the liquid outlet pipe 10;

[0042] In the process of solid-liquid separation, Figure 2 , Figure 4 As shown, the filter cartridge 8 is squeezed by the roller 13, so that the filter cartridge 8 is deformed to a certain extent, and the external water supply device transports water to the spray pipe 12 and sprays it out through the spray pipe 12. The water sprayed by the spray pipe 12 rinses the filter cartridge 8 to complete the cleaning of the filter cartridge 8, thereby preventing debris from adhering to the filter cartridge 8 during the solid-liquid separation process and affecting the efficiency of the filter cartridge 8 in separating solid and liquid materials.
