Filter with self-cleaning rotating filter element

Abstract

The invention provides a filter capable of automatically cleaning a rotary filter element, which consists of accessories such as a filter body (3), a filter element (17) with a hollow shaft, a bearing (8), a sealing element (6), a rotary joint, a cleaning roll brush (10), an electropneumatic valve (4), a drain pipe (5), an electric cabinet (1), an electric motor (16), a coupler (15), an overflow device (9), a liquid inlet pipe (11), a stander (2), a belt (13), a big belt pulley (14), a small belt pulley (12), a steel framework (20), a steel wire gauze and a filter material (18). The filter element (17) with the hollow shaft can effectively prevent impurities at one side of the filter element (17) with the hollow shaft from being absorbed and accumulated under dual actions of back flushing of cleaning liquid under the action of a centrifugal force and cleaning of the external surface of the filter element by the cleaning roll brush. The filter has the advantages that the filter can prevent a passage of the filter element from being blocked, can clean the filter element automatically, can discharge pollution by automatic timing, reduces cost for replacing the filter element, and saves expenses.

Description

technical field [0001] The invention relates to a large-scale liquid filter, in particular to a filter capable of self-cleaning a rotating filter core during operation. Background technique [0002] At present, the structure of large-scale liquid filter is mainly composed of filter body, filter element, connecting pipe, seal, connecting fastener, electrical control system and other accessories. In the main body of the filter, the filter element separates the liquid into two parts: the liquid containing impurities before filtration and the clean liquid without impurities after filtration. When the liquid passes through the filter element, only clean liquid without impurities can pass through the pores formed on the filter element, while solid impurities cannot pass through because they are captured by the filter element. Therefore, filter impurities accumulate on the outer surface of the filter element in the direction of liquid entry. According to such a filtration system, ...
