Background

At present, in the field of sewage filtration, particularly in a primary filtration system for removing sewage particle impurities, a filter screen is generally adopted for primary filtration; in some sewage pipelines with unstable water quality conditions, the mesh size of the filter screen is difficult to master, and if the filter screen adopts too fine meshes, the filtering speed is slow; if too large a mesh is used, there may be no filtration at all; in order to ensure the filtering effect, thinner meshes are generally adopted to adapt to the filtering of finer particle impurities; thus, this system is very inefficient at filtering relatively coarse contaminant particles.

For example, chinese patent CN105561660B proposes a sewage filtering system, which includes a filtering pipe, a front filtering net and a rear filtering net are arranged inside the filtering pipe; the front and rear filter screens are made of soft iron wires, and each soft iron wire can move transversely; the filter tube is also internally provided with a front annular plate and a rear annular plate which extend inwards from the inner wall of the filter tube in the radial direction, and the front annular plate and the rear annular plate are respectively clung to the front filter screen and the rear filter screen; a strip-shaped electromagnet is arranged on the central connecting line of the front filter screen and the rear filter screen, and the front filter screen and the rear filter screen are symmetrical about the middle section of the electromagnet; the front sides of the front filter screen and the rear filter screen are respectively provided with a front pressure gauge and a rear pressure gauge; the front pressure gauge, the rear pressure gauge and the electromagnet are coupled to a controller outside the filter pipe. This system is carrying out the in-process of just straining to sewage particle impurity, can initiatively adjust the mesh size of filter screen according to the size of foreign particles to compromise filtration speed and filter effect.

The device can't reach the purpose of in time clearing up the filter screen, can't avoid impurity too much and block up the filter screen, influences follow-up filtering operation's normal clear, can't realize many times deep filtration when filtering sewage, and simple structure can't realize solid-liquid separation's purpose, and the quality of filtering liquid is not high, and filterable speed influences filterable efficiency slowly.
