Application of filter in the filter tank

Stainless steel filter includes tank shell, multiple filters, backwash components, pressure drop controller, etc.
The partition in the towerless water supply tank frame divides the water tank into the top area and the bottom area. In the top area, there are some filters, which will help save filter space and save space.
The backwash suction cup is installed in the bottom area. During operation, the fluid enters the top tank space from the inlet, and then enters the wedge wire screen filter through the diaphragm plate. The larger impurities will be blocked, and the clean liquid will flow out from the outlet.

The wedge wire screen filter used in the stainless steel tank is a high-strength screen. The minimum gap we provide is 20 μ M. if the impurity mass accumulates on the surface, it can be automatically cleaned and filtered by controlling the pressure drop and timing. If the filter surface of the wedge wire screen filter is large enough, the pressure drop at the inlet and outlet will increase to the set value. If the timer is increased to the present time, the electric control box will be closed A signal will be sent to drive the backwash system.

If the inlet of the backwashing suction cup hole and the filter inlet hole is opened, the drain valve will be opened. At this time, the system will empty the pressure, and the relative pressure inside the suction cup and the filter will be lower than the lateral pressure in the negative pressure area of the filter, which will force the net circulating water of the filter to flow into the filter from the side, and the impurities on the inner wall of the filter will be discharged through the blowdown valve, which will improve the characteristics of the filter Special design and filter’s internal smooth, the structure is very easy to backwash, all impurities will be washed off.
