[0002] A large amount of low-concentration coal chemical wastewater is generated in coal chemical production, which contains a large amount of solid particles. When treating the wastewater, the solid particles in the wastewater need to be separated. The traditional method uses filter mesh to filter, but the solid particles are easily deposited on the filter mesh, resulting in reduced filtration efficiency.

[0003] Reference authorization announcement number: CN215609792U Chinese authorized patent: A low-concentration wastewater treatment equipment. The utility model can block the coal slag in the wastewater through the set conical filter. The set vibration component can drive the slider to vibrate up and down in the slide. The slider drives the two conical filter screens to vibrate up and down so that the coal slag on the conical filter screen is vibrated toward the small diameter end, and then falls out from the bottom of the tank through the pipe from the small diameter end, thereby realizing automatic cleaning of the coal slag on the conical filter screen.

[0004] However, in the process of filtering wastewater, coal slag will adhere to the conical filter. As the wastewater filtration increases, the coal slag will accumulate and block the mesh holes on the conical filter, thereby affecting the filtering effect of the conical filter.

The outer diameter of the guide tube 8 matches the inner diameter of the feed hopper 2 to ensure the sealing between the feed hopper 2 and the guide tube 8. A driven bevel gear 9 meshing with the active bevel gear 5 is welded to the outer wall of the guide tube 8. A filter cover 10 is welded to the outer wall of the guide tube 8.
