[0016] Please see Figures 1-3This utility model provides an embodiment of a solid-liquid separation device for sewage and sludge treatment, including a support 1, a water storage tank 2 fixedly connected to the inner wall of the support 1, a compression shell 7 fixedly connected to the inner wall of the water storage tank 2, a plate groove 9 opened at the outlet end of the compression shell 7, a sealing door 10 slidably connected to the inner wall of the plate groove 9, a first electro-hydraulic push rod 11 fixedly connected to the side wall of the compression shell 7, the movable end of the first electro-hydraulic push rod 11 fixedly connected to the lower surface of the sealing door 10, a push plate 12 slidably connected to the inner wall of the compression shell 7, and a second electro-hydraulic push rod 13 fixedly connected to the outer wall of the compression shell 7, the movable end of the second electro-hydraulic push rod 13... A pressure plate 14 is rotatably connected to the inner wall of the compression housing 7, which is fixedly connected to the side wall of the push plate 12. A hinge 15 is fixedly connected to the upper surface of the pressure plate 14. A first rotating shaft 16 is rotatably connected to the inner wall of the hinge 15. A fixing member 17 is fixedly connected to the upper surface of the compression housing 7. A second rotating shaft 18 is rotatably connected to the inner wall of the fixing member 17. A mounting base 19 is fixedly connected to the surface of the second rotating shaft 18. A third electro-hydraulic push rod 20 is fixedly connected to the inner wall of the mounting base 19. The movable end of the third electro-hydraulic push rod 20 is fixedly connected to the surface of the first rotating shaft 16. When solid-liquid separation of sewage sludge is required, the sewage sludge is first transported to the compression housing. Inside the body 7, the third electro-hydraulic actuator 20 is then activated, its movable end driving the first rotating shaft 16 to move. Through the hinge 15, the pressure plate 14 rotates around the rotating connection with the compression housing 7, thus initially compressing the sewage sludge inside the compression housing 7, causing some liquid to flow into the storage tank 2 through the permeation hole 8. Subsequently, the second electro-hydraulic actuator 13 is activated, its movable end pushing the push plate 12 to slide against the inner wall of the compression housing 7, further compressing the sewage sludge. More liquid seeps out through the permeation hole 8 and flows into the storage tank 2, achieving solid-liquid separation. After solid-liquid separation is completed, the first electro-hydraulic actuator 11 is activated, its movable end... The closed door plate 10 slides upward within the plate groove 9, opening the outlet end of the compression housing 7. Then, the second electro-hydraulic push rod 13 continues to push the push plate 12, pushing the compressed solid sludge out from the outlet end of the compression housing 7. Through the initial squeezing of the pressure plate 14 and the further compression of the push plate 12, the sewage sludge can be squeezed multiple times, making the solid-liquid separation more thorough and improving the separation effect. The use of electro-hydraulic push rods to drive the closed door plate 10, push plate 12 and pressure plate 14 has a high degree of automation, is easy to operate, and can effectively improve work efficiency. At the same time, the compressed sludge forms a sludge cake, which is convenient for subsequent transportation and centralized treatment.

[0017] In this embodiment, the outer wall of the compression housing 7 is provided with several permeation holes 8 for leakage. A detachable sealing plate 3 is slidably connected to the side wall of the water storage tank 2. A handle 4 is fixedly connected to the side wall of the sealing plate 3. A drain pipe 5 is fixedly connected to the side wall of the water storage tank 2. A shut-off valve 6 is provided at the outlet end of the drain pipe 5. The liquid collected in the water storage tank 2 can be discharged through the drain pipe 5 by opening the shut-off valve 6. When it is necessary to clean the water storage tank 2, the sealing plate 3 can be pulled by the handle 4 to slide it out from the side wall of the water storage tank 2 for easy cleaning. The detachable sealing plate 3 on the side wall of the water storage tank 2 facilitates the cleaning and maintenance of the inside of the water storage tank 2, ensuring the normal operation of the device. The water storage tank 2 controls the liquid discharge through the drain pipe 5 and the shut-off valve 6, and the separated liquid can be discharged in a timely manner according to the actual situation to avoid secondary pollution.

[0018] When solid-liquid separation of sewage sludge is required, the sewage sludge is first transported into the compression housing 7. Then, the third electro-hydraulic push rod 20 is activated, and its movable end drives the first rotating shaft 16 to move. Through the hinge 15, the pressure plate 14 rotates around the rotating connection with the compression housing 7, thereby initially squeezing the sewage sludge in the compression housing 7. This allows some liquid to flow into the storage tank 2 through the permeation hole 8. Subsequently, the second electro-hydraulic push rod 13 is activated, and its movable end pushes the push plate 12 to slide on the inner wall of the compression housing 7, further compressing the sewage sludge. More liquid seeps out through the permeation hole 8 and flows into the storage tank 2, achieving solid-liquid separation. After solid-liquid separation is completed, the first electro-hydraulic push rod 11 is activated, and its movable end drives the sealing door plate 10 to slide upward in the plate groove 9, opening the outlet end of the compression housing 7. Then, the second electro-hydraulic push rod 13 continues to push the push plate 12, pushing the compressed solid sludge out from the outlet end of the compression housing 7.

[0019] Through the initial compression of the pressure plate 14 and the further compression of the push plate 12, the sewage sludge can be squeezed multiple times, making the solid-liquid separation more thorough and improving the separation effect. The closed door plate 10, push plate 12 and pressure plate 14 are driven by an electro-hydraulic actuator, which has a high degree of automation, is easy to operate and can effectively improve work efficiency. At the same time, the compressed sludge forms a sludge cake, which is convenient for subsequent transportation and centralized treatment. The sealing plate 3 can be pulled out from the side wall of the water storage tank 2 by the handle 4, which is convenient for cleaning the inside. The side wall of the water storage tank 2 is equipped with a removable sealing plate 3, which facilitates the cleaning and maintenance of the inside of the water storage tank 2 and ensures the normal operation of the device. The liquid discharge of the water storage tank 2 is controlled by the drain pipe 5 and the shut-off valve 6. The separated liquid can be discharged in a timely manner according to the actual situation to avoid secondary pollution.
