Backwash water quality filter system

Abstract

The invention discloses a backwash water quality filter system. The backwash water quality filter system comprises a water supply branch and a backwash branch, which are connected with each other in parallel, wherein both the water supply branch and the backwash branch are respectively provided with a valve and a filter in serial connection in the direction from a water inlet to a water outlet, a filter element is arranged inside each filter to divide a chamber of a shell into a liquid inlet cavity and a liquid outlet cavity, the liquid inlet cavity is communicated with the water inlet through the valve, the liquid outlet cavity is communicated with the water outlet, and the filter on the water supply branch is provided with a sewage discharge pipe which can be opened and closed and through which the liquid inlet cavity is communicated with the exterior; in the application process, the backwash branch valve is closed, the water supply branch valve is opened, the backwash water quality filter system stays at a normal water supply state at the moment, and the impurities can be removed; after the backwash water quality filter system is used for a period of time, the water supply branch valve is closed, the backwash branch valve is opened, and the sewage discharge pipe on the water supply branch filter is opened to carry out the backwash. By adopting the structure, the maintenance frequency of the water quality filter system can be reduced; moreover, in the maintenance process, the filter for the supply water can be guaranteed, and the normal production can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of pipeline filtering equipment, in particular to a backwashing water quality filtering system. Background technique [0002] Mine dust-proof sprinkler design is an important content of mine design, which is a part of safety technical measures, and its purpose is to solve the labor hygiene and production safety of mine production. The "Coal Mine Safety Regulations" clearly stipulates: "Mines must take comprehensive dust prevention measures and establish a complete dust prevention and sprinkler pipeline system." Therefore, mine dust prevention and sprinkler design must be done well. [0003] In the prior art, after a period of use, the filter element in the water quality filter used in coal mines will be clogged due to the accumulation of a large amount of impurities and particles. At this time, the use must be stopped, and the filter must be disassembled for cleaning, which will affect the normal use of the ...

Problems solved by technology

[0003] In the prior art, after a period of use, the filter element in the water quality filter used in the coal mine will be blocked due to the accumulation of a large amount of impurities and particles. At this time, the use must be stopped, and the filter must be disassembled for cleaning, which will affect the normal use of the filter. and normal production, reducing production efficiency
