Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment slag separation device. Background Art

[0002] Sewage usually contains paper scraps, fibers, grease, resin, scum and other suspended matter. If these impurities are not removed in time, they may cause wear or blockage to subsequent process equipment in the sewage treatment system, thereby affecting the stability and efficiency of the entire sewage treatment process. Therefore, before sewage treatment, it is necessary to use a sewage treatment slag separator to isolate and filter out the slag in the sewage.

[0003] The most commonly used slag separator is in the form of a conveyor belt. One end is placed in the wastewater, and as the chain belt moves upward, the residue left on the chain belt is carried out, thereby separating the slag. However, the residue carried out during use still contains a lot of sewage, requiring secondary extrusion operations. Utility Model Content

The pipe and the drum are arranged to avoid each other. As the drum rotates, the residue will be transported to one end of the inlet and outlet by the auger piece, and the sewage flows out through the leakage hole on the surface of the drum, and the outflowing waste liquid enters the liquid collecting assembly and is collected. The waste residue flips and falls in the drum during the transportation process, which can make the sewage and residue separated more thoroughly.
