Product Overview

Automatic backwash filter is mainly composed of simplified, stainless steel filter, electric blowdown valve and blowdown device. When the water filter is working, the backwash butterfly valve plate is opened, and the water flow enters the filter element from the inlet. After filtering through the filter screen, the water flows out of the system, and the impurities are intercepted in the filter element. When the water processor needs to discharge, close the butterfly valve plate, open the discharge valve, the water flow through the filter screen second half of the outside into the inside, through the first half of the filter, part of the water flow into the system from the outlet, the rest of the water flow from the filter screen second half of the outside into the inside, through the sewage discharge outlet, play the role of reverse automatic washing filter screen.

Principle of Operation

Under normal circumstances, the steering valve is opened, and the water flow is filtered through the filter barrel and discharged from the outlet. When the sewage valve station is opened, the total flow rate of the filtered liquid increases and the flow rate increases. The impurities stuck on the wall of the filter tube are impulsive. the impurities are discharged from the sewage outlet. Most of them flow out from the outlet, and some of them enter the filter cylinder from the outside of the filter through the mesh of the impurity collection section, resulting in backwashing of the filter cylinder, so as to achieve the effect of washing the impurities adhering to the mesh from the outside of the filter cylinder, and the impurities are still discharged through the sewage outlet.
