[0030] It also includes a scraper 14, which is arranged on one side of the lower end of the separation chamber 3, and the scraper 14 is in contact with the lower end of the separation chamber 3. A cleaning brush 16 is arranged on one side of the scraper 14, and the cleaning brush 16 is connected to the scraper 14 through three equidistantly distributed L-shaped connecting blocks 15.

[0031] When in use, sewage enters the separation chamber 3 of the main body 1 through the feed port 2, and the sewage passes through the through hole 12 and the filter plate 9 in the separation chamber 3 and enters the water collecting chamber 10, and the liquid is discharged through the liquid outlet pipe 11, and solid impurities accumulate at the lower end of the separation chamber 3. The hydraulic cylinder 4 is started to press the pressure plate 5 downward to apply pressure to the sewage, so that the solid matter and the liquid are in closer contact and compressed, thereby improving the solid-liquid separation efficiency. Subsequently, the electric telescopic rod 13 is started to drive the scraper 14 to push the solid impurities into the discharge chamber 6, and the motor 7 drives the spiral conveying rod 8 to rotate to transport the solid impurities to the outside of the main body 1, which can avoid the problem of blockage of the discharge. The overall operation is simple and convenient, and the practicality is good.

[0032] See also Figure 3 A motor 7 is provided on one side of the discharge chamber 6, and the output end of the motor 7 is connected to the screw conveying rod 8 through a coupling. The motor 7 can stably and continuously drive the screw conveying rod 8 to rotate, thereby realizing smooth transportation of solid impurities;

[0033] See also Figure 3 A hydraulic cylinder 4 is installed at the upper end of the separation chamber 3, and the output end of the hydraulic cylinder 4 is connected to the pressure plate 5. The hydraulic cylinder 4 can provide a stable and strong pressure, so that the pressure plate 5 can evenly press the sewage downward, thereby effectively separating the solid matter from the liquid;

[0034] See also Figure 3 and Figure 4 An electric telescopic rod 13 is provided on the front and rear sides of one side of the separation chamber 3, and the output ends of the electric telescopic rod 13 are connected to the scraper 14. The electric telescopic rod 13 can accurately control the moving trajectory and speed of the scraper 14 to ensure that the scraper 14 can accurately push the solid impurities into the discharge chamber 6;

[0035] See also Figure 3 A filter plate 9 is provided below the spiral conveying rod 8, and the discharge chamber 6 is connected to the water collecting chamber 10 through the filter plate 9. The filter plate 9 can effectively filter out the residual water in the solid impurities, further improving the effect of dry-wet separation;

The opening and closing of the sealing door 17 is convenient and flexible, which is convenient for operators to take out the cleaned solid impurities. The use of the rectangular rubber sealing ring 18 ensures the sealing of the sealing door 17 when it is closed, effectively preventing sewage leakage and odor diffusion;

[0037] See also Figure 1 and Figure 3 A feed port 2 is provided on the upper side of the rear end of the main body 1, and a liquid outlet pipe 11 is provided at the rear end of the water collecting chamber 10, and one end of the liquid outlet pipe 11 extends to the outside of the water collecting chamber 10. The setting of the feed port 2 facilitates the introduction of sewage into the treatment equipment, and the setting of the liquid outlet pipe 11 facilitates the discharge of the treated liquid from the equipment, which is convenient for subsequent treatment or utilization.

[0038] Working principle: When in use, sewage is added from the feed port 2, and the sewage will enter the interior of the separation chamber 3. Part of the sewage will enter the interior of the separation chamber 3. The through hole 12 at the lower end of the separation chamber 3 and the filter plate 9 at the lower end of the discharge chamber 6 can allow the sewage to enter the interior of the water collecting chamber 10. The operator can discharge the liquid through the liquid outlet pipe 11. At this time, solid impurities in the sewage will accumulate at the lower end of the separation chamber 3. Start the hydraulic cylinder 4, and the output end of the hydraulic cylinder 4 will drive the pressure plate 5 to move downward. The pressure plate 5 will apply a downward pressure to the sewage in the separation chamber 3. This pressure can force the solid matter in the sewage, such as particles, sediments, etc., to contact more closely with the liquid part and be compressed. During the compression process, the gaps between the solid substances are reduced, and the water is further squeezed out, thereby achieving more efficient solid-liquid separation. Then start the electric telescopic rod 13, and the electric telescopic rod 13 will drive the scraper The plate 14 moves toward the discharge chamber 6, so that the scraper 14 can push the solid impurities so that they can enter the interior of the discharge chamber 6. At this time, the motor 7 is started, and the motor 7 will rotate the screw conveying rod 8 through the coupling. The rotation of the screw conveying rod 8 will produce a spiral conveying effect, so that the solid impurities can be transported to the outside of the main body 1. At the same time, the water filtering operation can be further performed through the filter plate 9 during transportation, so that the dry-wet separation effect is more significant. When the dry-wet separation is completed, the electric telescopic rod 13 can be started to retract back and forth, so that the scraper 14 can drive the cleaning brush 16 to move synchronously. In the process of moving back and forth, the cleaning brush 16 can fit closely to the surface of the through hole 12, effectively removing the accumulated solid impurities, and the operator can easily remove the cleaned impurities by opening the sealing door 17, effectively avoiding the influence of solid impurities on the subsequent dry-wet separation.
