Description

A chemical pump filter device

technical field

The utility model belongs to the field of liquid filtering devices, in particular to a chemical pump filtering device.

Background technique

In the chemical industry, chemical pumps are often used to transport liquid materials. During the transportation process, the liquid moves through the impeller of the chemical pump. When the liquid contains solid particles, these solid particles will continuously collide with the impeller and the inner surface of the chemical pump, damaging the impeller and the chemical pump. The inside of the chemical pump shortens the service life of the chemical pump. In severe cases, it will block the impeller flow channel and destroy the sealing performance of the pump. Therefore, a filter device is often installed in front of the chemical pump. The existing filter device is often unable to clean the filter screen. After a long time of use, the filter screen will also be blocked by solid particles. It is necessary to disassemble the filter screen for cleaning or replace the filter screen, which wastes manpower, increases operating costs, and reduces work efficiency.
