filter and its use characteristics

Sep 18, 2019

The automatic backflush filter is composed of a tank body, a filter column, a recoil mechanism, an electric control box, a speed reducer, an electric valve and a differential pressure controller. The diaphragm in the tank divides the inner cavity into a turbid liquid chamber and a clear liquid chamber, and a plurality of filter columns are mounted on the horizontal partition; the turbid liquid sent from the pump enters the turbid liquid chamber and enters the filter column through the partition hole. The inner cavity, the clear liquid passes through the gap to the clear liquid chamber, and all the filtered liquid is merged in the clear liquid chamber and finally sent out from the outlet. When the impurities accumulate in the filter column to a certain thickness, a pressure difference is generated between the turbid liquid chamber and the clear liquid chamber. At this time, the recoil mechanism can be automatically controlled by the differential pressure controller, or the backwash system can be manually activated to remove the filter residue.

 

The automatic backflush filter uses its own filtered supernatant to self-clean the filter column without the need to remove the filter and clean, and does not require an additional cleaning system. Since it has several filter columns installed in the tank at the same time, each filter column is washed one by one during the backwashing, and the other filter columns continue to work to ensure continuous liquid supply.
