Abstract

The invention relates to a method for manufacturing sewage intake equipment with a preliminary filtering function, which comprises the following steps: firstly, arranging a squirrel-cage-shaped filtering structure layer at the outside of the equipment; then, connecting an internal water intake sieve tube and a sewage intake pipeline; and finally, arranging a framework on the squirrel-cage-shaped filtering structure layer. The invention is used for carrying out preliminary filtering processing for sewage to prevent the blockage of pipelines, valves, water pumps, heat exchangers or heat pump unit equipment. The sewage intake equipment has the advantages of simple and applicable structure, easy manufacture and installation, convenient use and management as well as preliminary filtering and back flushing functions.

Description

technical field [0001] The invention relates to a method for making sewage water intake equipment with primary filtering function. Background technique [0002] At present, in the process of extracting and applying urban sewage, the suspended and granular impurities contained in the sewage are extremely harmful, which can easily cause blockage of water pumps, heat exchangers, pipes, valves and other equipment, making the heat pump units unable to operate normally. Sewage water intake equipment does not have good filtering and backwashing functions. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a method for manufacturing sewage water intake equipment with preliminary filtering function, which has a simple and applicable structure, is easy to manufacture and install, and is convenient for operation and management. [0004] The technical scheme of the present invention is: a kind of method of making...
