Description

Electric drive back flush filter

Technical Field

The utility model relates to a sewage treatment technical field specifically is an electric drive back flush filter.

Background

The back washing filter is a precise device which directly intercepts impurities in water by using a filter screen, removes suspended matters and particles in the water body, reduces turbidity, purifies water, reduces the generation of system dirt, bacteria, algae, rust and the like, and purifies the water and protects other devices of the system to normally work. Water enters from the inlet, and larger particles of impurities are filtered out through the coarse filter screen and then reach the fine filter screen. In the filtering process, the fine filter screen gradually accumulates dirt and impurities in water to form a filtering impurity layer, the impurity layer is accumulated on the inner side of the fine filter screen, therefore, a pressure difference is formed between the inner side and the outer side of the fine filter screen, when the pressure difference of the filter reaches a preset value, the automatic cleaning process is started, the supply of purified water is not cut off, the cleaning valve is opened, the water pressure in the cleaning chamber and the dirt suction device is greatly reduced, and a suction force is generated between the dirt suction pipe and the cleaning chamber through the suction nozzle through the pressure difference between the filter cylinder and the dirt suction pipe to form a dirt suction process. Meanwhile, the electric motor drives the sewage suction pipe to do spiral motion along the axial direction. The combination of the axial movement and the rotary movement of the dirt suction device can completely clean the inner surface of the whole filter screen. The whole flushing process takes only tens of seconds. The blow-down valve is closed at the end of the purge. The filter begins to prepare for the next flush cycle.
