Automatic backwashing stack filter is a self-cleaning device used for continuously filtering particles in low-viscosity fluids. One of its major features is its high reliability and low maintenance cost.

30 to 1000μ m to ensure the effective separation of impurities in the fluid. When the pressure difference before and after the filter element reaches the set value, backwashing should be started immediately for self-cleaning. Filtration will not be interrupted during backwashing. Solid particles in the fluid can accelerate the wear of system components, pipes and valves, and these impurities can cause premature failure of system components. Therefore, to address the impact of particles in the fluid on the quality of processed products, it is necessary to font-size: 14px;" > Automatic backwash disc filter .

Automatic backwashing stack filter < /span> Feature:

The conical filter element ensures the uniform distribution of medium flow during filtration and backwashing. Continuously complete filtration and backwashing ( regeneration ) and the entire working process of sewage discharge. The four filter elements in the filter chamber are installed on the rotating piston, which is driven by the rotating mechanism at the bottom of the filter. Each time, the isolation cleaning filter element at the backwashing working position is put into use at a rotation Angle of 90 degrees. At the same time, drive the filter element in the next working process to rotate to the backwashing working position for isolation. Open the drain valve of the automatic backwashing disc filter. A high pressure difference is generated between the inside and outside of the filter element, filtering out the external clear water that passes through the filter element at high speed and flows out from the drain valve. Under high-speed flushing, the contaminants inside the filter element are washed away.

Automatic backwashing stack filter < /span> Filter element positioning mechanism: The pneumatic actuator is connected to the filter body through a one-way clutch. The positioning of the actuator is protected and monitored through position switches and elastic locking positions to ensure that the positions of the filter element and the flow channel interface do not shift. If the elastic locking function is not used, under the action of inertial force, the interface between the filter element and the flow channel will shift after long-term operation and load changes, which will reduce the flow rate and ultimately affect the backwashing effect.

Automatic backwashing stack filter Structure: The filter element adopts stainless steel wire with a wedge-shaped cross-section wound and welded on the polygonal frame, which has high strength, corrosion resistance and corrosion resistance. The filtration gap formed between every two adjacent steel wires and the V area in the direction of the return filtrate intercept particles larger than the gap. The filtration accuracy is stable and reliable. Meanwhile, the angled V area increases the flow rate, which is conducive to the shedding and removal of impurities adhering to the filter screen during backwashing.

Automatic backwashing stack filter Automatic backwashing stack filter Due to its compact structure, high reliability, low operating cost and long service life, it is suitable for all industries that remove solid particles from low-viscosity fluids. Only the materials of filter elements and seals need to be replaced according to different filtrates, making it an ideal choice for many industrial sectors.
