The self-cleaning filter first passes through a coarse filter to filter out larger particles

2021-05-08

Self-cleaning filter it is a machine that can treat sewage all by itself, which is the same as our fully automatic washing machine. After you pour the sewage in, it can automatically descale and derust the sewage. Below, we will introduce you to its function and working principle, you can come to find out!

The fully automatic backwash filter can make industrial sewage meet the required wastewater discharge standards, which can effectively protect the environment. At the same time, it can also treat the sewage to a standard that can be reused. This will not only solve the problem of sewage discharge, but also It can be reused and save costs. The automatic backwash filter is a filter that directly intercepts impurities in the water, removes suspended solids and particles in the water body, reduces turbidity, purifies water quality, and reduces system dirt, bacteria, algae, rust, etc. To improve water quality and protect other equipment working properly.

Water enters from the inlet, first passes through the coarse filter to filter out larger particles of impurities, and then reaches the fine filter. In the filtering process, the fine filter gradually accumulates dirt and impurities in the water to form a filter impurity layer, which is accumulated on the inside of the fine filter, so a pressure difference is formed on the inner and outer sides of the fine filter. . When the pressure difference of the filter reaches the preset value, the automatic cleaning process will start. During this time, the clean water supply is continuously flowing, the cleaning valve is opened, and the water pressure in the cleaning chamber and the sewage suction device drops significantly, passing through the filter cartridge and the sewage suction pipe. Due to the pressure difference, a suction force is generated between the suction pipe and the cleaning chamber through the suction nozzle, forming a dirt suction process. At the same time, the electric motor drives the sewage suction pipe to make a spiral movement in the axial direction. The combination of axial movement and rotary movement of the dirt sucker completely cleans the entire inner surface of the filter. The entire flushing process only takes tens of seconds. The drain valve is closed at the end of cleaning. The filter is ready for the next flush cycle.
