Crushing grid type sewage lifting device

Abstract

The invention discloses a crushing grating type sewage lifting device which comprises a water tank and a water pump arranged on one side of the water tank, a crusher is fixedly connected to the left side of the top of the water tank in a penetrating mode, grating plates are fixedly connected to the positions, located on the left side and the right side of the crusher, in the water tank, and meshes of the left grating plate are larger than those of the right grating plate in size. And the bottom of the right side of the water tank is fixedly connected with a water pumping pipe in a penetrating manner. According to the crushing grating type sewage lifting device, the crusher is matched with the grating plate, so that large-particle impurities in the area A can be crushed into small blocks, the small blocks are discharged into the area B and then pumped and discharged by the water pump, the impurities can be prevented from blocking a pipeline or damaging the water pump, and the probability of paralysis of a sewage discharging system is reduced; meanwhile, part of discharged sewage can be sprayed to the surface of the grating plate through cooperation of a backwashing pipe and a water spraying square pipe, impurities attached to the surface of the grating plate can be washed off, then smooth water passing from the area A to the area B can be kept, and the water drainage efficiency is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a broken grid type sewage lifting device. Background technique [0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or for reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage generated in daily life, which refers to a complex mixture of various forms of inorganic and organic matter, includi...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a broken grid-type sewage lifting device, which solves the problem that when plastic bags, rags, sanitary napkins, keys, and mobile phones enter the pipeline, the pipeline will be blocked in the light one, and the pump body will be damaged in the serious one. The whole equipment fails, which affects the normal operation of the system; after the equipment is used for a long time, the suspended matter in the sewage adheres to the side wall of the water tank, which can only be cleaned manually on a regular basis
