Description

Technical Field

[0002] By-pass filtration does not mean installing the filter on the main circulation pipeline to filter all the circulating water, but rather drawing out a part of the circulating water from the main circulation pipeline for filtration. It filters the impurities in the system through gradual and multiple circulation interception, and finally removes the impurities from the system through necessary backflushing.

[0003] The side filter is the main equipment used for side filtering, and the Chinese authorized patent announcement number: CN 213790288U records "an automatic cleaning device for a side filter". The motor drives the active shaft to rotate, that is, drives the first pulley to rotate, and the first pulley drives the synchronous belt to rotate. The synchronous belt drives the second pulley to rotate, thereby driving the driven shaft to rotate. The rotation of the active shaft and the driven shaft drives the active rod to rotate, and then drives the driven rod to rotate. The driven rod drives the slider, that is, drives the cleaning brush to slide on one side of the guide rod, so as to clean the impurity residue on the filter plate, thereby increasing the cleaning effect, reducing the impurity residue, and improving the use effect of the side filter.
