[0035] The sewage discharge structure 8 is located inside the outer casing 5. The sewage discharge structure 8 includes a fixing frame 801 fixed inside the outer casing 5 and connected to the top of the filter screen 12, a conveying pipe 804 fixed inside the outer casing 5 and connected to the bottom of the filter screen 12, a slag discharge pipe 803 fixed to one side of the conveying pipe 804, and a conveying component located inside the conveying pipe 804.

[0036] like Figure 1 , Figure 2 ,Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the conveying assembly further includes a drive motor 806 installed on one side of the bottom end of the conveying pipe 804, a protective shell 805 sleeved on the outside of the drive motor 806 and connected to the conveying pipe 804, a partition 809 fixed inside the bottom end of the conveying pipe 804, a spiral blade shaft 808 rotatably connected inside the conveying pipe 804 and connected to the rotating end of the drive motor 806, a transmission rod 807 rotatably connected to the top end of the partition 809, a scraper 802 fixed on the outside of the transmission rod 807, and a bevel gear set 810 disposed between the transmission rod 807 and the spiral blade shaft 808. The spiral blade shaft 808 passes through the partition 809 and is connected to the drive motor 806.

The front cross-section of the fixed frame 801 is a funnel-shaped inclined structure, and the scraper blade 802 has a spiral structure. When too much sludge accumulates on the surface of the filter screen 12, the drive motor 806 is started to drive the spiral blade shaft 808 to rotate. At the same time, the spiral blade shaft 808 drives the transmission rod 807 to rotate via the bevel gear set 810, so that the transmission rod 807 drives the scraper blade 802 to scrape off the sludge accumulated on the surface of the filter screen 12. Then, the sludge falls along the inclined surface of the filter screen 12 into the interior of the conveying pipe 804. By rotating the spiral blade shaft 808, the sludge is pushed to move inside the conveying pipe 804 and discharged through the sludge discharge pipe 803, thus completing the cleaning of the sludge.

When the liquid level of the wastewater inside the housing 5 is higher than the slag discharge pipe 803, the float 707 is below the water surface. The buoyancy of the float 707 pushes the moving block 706 to move upward, so that the water tank 705 is misaligned with the water supply pipe 6, blocking the wastewater from entering the interior of the housing 5 and preventing the wastewater from overflowing. When the water level drops, the spring 704 pushes the moving block 706 to reset, so that the wastewater flows through the water tank 705 into the interior of the housing 5. The pressure plate 703 is raised or lowered by rotating the screw 702, which squeezes or relaxes the spring 704, adjusting the elasticity of the spring 704.
