An automatic backwash filter is an advanced, efficient, and easy-to-operate automatic filter. The filter is composed of a tank body, stainless steel filter screen, sewage part, transmission device, and electrical control part. When the filter operates, the water to be filtered enters through the water inlet, flows through the filter screen, enters the pipeline required by the user through the outlet for process circulation, and the particles in the water are trapped inside the filter screen. At the same time, the blowdown outlet is opened and discharged from the blowdown outlet. When the filter screen is cleaned, the pressure difference is reduced to the minimum value, the system is returned to the initial filtering state, and the system is in normal operation.
The filtered liquid enters the filter from the inlet, enters the filter through the lower fixing plate, the liquid flows from the inside of the filter to the outside, and flows out of the filter from the outlet of the filter cartridge, and the impurities discharged from the backwash are discharged from the drain outlet
Solid particles are trapped inside the screen as the liquid flows from the inside to the outside. As the contamination increases, the differential pressure between the contaminated site and the clean side of the filter increases. When the differential pressure reaches the set value, the differential pressure gauge sends a message and the filter starts the automatic backwashing process.
A backwashing filter is an indispensable treatment method in the process of water purification, which is used to intercept impurities in the water to purify water quality or protect the normal operation of other equipment in the system. When the traditional filter works, the equipment must be disassembled to realize the cleaning of the filter part, and the filter state can not be monitored. Moreover, it is greatly affected by human factors, so the automation degree of the whole system is very low. When the backwash filter is cleaned and drained, the uninterrupted water supply of the system has the advantages of high automation degree, large treatment capacity, self-cleaning and drainage, uninterrupted water supply, wide application area, etc
