Abstract

The invention relates to the technical field of backwashing filters, in particular to an automatic backwashing filter which comprises a valve body, filter assemblies and a control assembly, and the valve body is provided with a liquid inlet, a liquid outlet and a drain outlet; the number of the filter assemblies is at least two, each filter assembly comprises a valve element assembly and a filter element assembly, and the valve element assemblies are communicated with the filter element assemblies; and the control assembly is arranged on the valve body and suitable for controlling any valve element assembly to be switched between the filtering state and the flushing state. When the filter element assemblies need to be backwashed, the control assembly is started to drive one of the valve element assemblies to be in a washing state, and at the moment, other filter assemblies are not influenced and still filter. Through the arrangement of the control assembly and the multiple sets of filtering assemblies, the filtering assemblies can be sequentially and independently cleaned, the other uncleaned filtering assemblies can normally conduct filtering operation during cleaning, and the filtering efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of backwashing filters, in particular to an automatic backwashing filter. Background technique [0002] The existing backwash filter mainly includes a valve body, a filter element disposed in the valve body, and a liquid inlet stop valve disposed in the valve body. When filtering the emulsion, the emulsion medium flows into the liquid inlet stop valve from the liquid inlet, and flows into the The filter element, the emulsion filtered by the filter element flows out in the outlet channel. When backwashing, close the stop valve to stop the emulsion from entering, and open the backwash port at the same time to backwash the filter element, and the impurity liquid after backwashing is discharged from the sewage outlet. [0003] In the existing backwashing filter, the two operation steps of filtering and backwashing are carried out separately. When backwashing is performed, the filtering operation will stop, whic...
