Submersible sewage pump for sewage treatment of paper making factory

Abstract

The invention provides a submersible sewage pump for sewage treatment of a paper making factory. According to the submersible sewage pump, the technical problems that an existing submersible sewage pump is simple in cutting mode, cannot cut sewage in a pump body multiply and is poor in cutting capability and cutting effect are solved. The submersible sewage pump for sewage treatment of the paper making factory comprises a worktable. A floating and sinking mechanism capable of adjusting the water level height of the worktable is arranged on the worktable, a balancing mechanism capable of maintaining the stability of the worktable is arranged on the worktable, and a mounting seat is fixed to the worktable. A submersible sewage pump body is arranged on the mounting seat and comprises a pump main body, a submersible motor, a base and a side cover. The pump main body is provided with a water inlet and a water outlet, the water inlet is formed in the lower end of the pump main body, a waterinlet filter mechanism communicating with the water inlet is arranged at the water inlet, the water outlet is formed in the side of the pump main body, and a water outlet filter mechanism communicating with the water outlet is arranged at the water outlet. The submersible sewage pump for sewage treatment of the paper making factory has the characteristic of being good in cutting effect.

Description

Technical field [0001] The invention belongs to the field of fluid machinery and relates to a submersible sewage pump, in particular to a submersible sewage pump used for sewage treatment in a paper mill. Background technique [0002] The composition of papermaking wastewater from paper mills is very complex, and its composition depends not only on the pulp method, but also on various factors such as the type of product and the type of raw materials. The suspended matter in the wastewater from the papermaking industry mainly comes from bark, grass clippings, silt in the material preparation section, as well as the ash, slag, fiber and filler lost in the various processes of pulping and papermaking. The submersible sewage pump is a submersible sewage pump, which can tear and cut long fibers, bags, belts, grass, cloth strips and other materials in the sewage, and then discharge them smoothly. It is especially suitable for conveying liquids containing hard solids and fibrous materia...
