Stainless steel filter, by the shell, multiple filter element, backwashing mechanism, and differential pressure controller and other parts of the composition of the stainless steel filter shell, the inner chamber is divided into the upper and lower two chambers, the upper chamber is equipped with a plurality of filter elements, so as to make full use of the filter space, significantly reducing the volume of the filter, the lower chamber is installed with a backwash suction cup. When working, the turbid liquid enters the lower chamber of the filter through the entrance, and then enters the inner chamber of the filter through the partition hole. Impurities greater than the gap of the filter element are trapped, and the net liquid passes through the gap to the upper chamber, and finally is sent out from the outlet.

The filter core adopts high strength wedge filter screen, and automatically cleans the filter core by pressure difference control and timing control. When the impurities in the filter accumulate on the surface of the filter element, causing the inlet and outlet pressure difference to increase to the set value, or the timer reaches the preset time, the electric control box sends a signal to drive the backwashing mechanism. When the backwashing suction plate port is directly aligned with the inlet of the filter element, the drain valve will be opened. At this time, the system will relieve pressure and drain, and a negative pressure zone with relative pressure lower than the water pressure outside the filter element will appear on the inside of the suction plate and the filter element, forcing part of the net circulating water to flow into the inside of the filter element, and the impurity particles adsorbed on the inner wall of the filter element will enter the pan with the water flow and be discharged from the drain valve. The specially designed filter screen creates a spray effect inside the filter element, and any impurities will be washed away from the smooth inner wall.

1. The filter equipment adopts the internal mechanical structure of patented technology to realize the high-pressure backwashing function in the true sense, which can easily and carefully remove the impurities trapped by the filter screen, clean no dead Angle, and the flux is not attenuated, ensuring the filtration efficiency and long service life.

2, stainless steel filter using 304, 316L stainless steel wedge filter, high strength, high precision, corrosion resistance, high filtration accuracy up to 25 microns.

3, stainless steel filter through its own retrieval and strain function to achieve automatic backwashing, can cope with unstable water quality fluctuations, without manual intervention.

4, stainless steel filter less wearing parts, no consumables, low operation and maintenance costs, simple operation and management.

5, stainless steel filter operation fine, can flexibly adjust the backwash pressure difference time and time setting value according to different water sources and filtration accuracy.

6, stainless steel filter in the backwashing process, each (group) filter screen in turn backwashing operation; Ensure that the filter screen is cleaned safely and efficiently, while other filters are not affected and continue to filter.

7, stainless steel filter using pneumatic blowdown valve, backwashing time is short, backwashing water consumption is less, environmental protection and economy.

8, stainless steel filter structure design is compact and reasonable, occupying a small area, flexible installation and convenient movement.
