Anti-blocking composite filter element

Abstract

The invention discloses an anti-clogging composite filter element, and belongs to the field of filter elements, the anti-clogging composite filter element comprises a pair of sealing rings, a main filter ring is fixedly connected between the pair of sealing rings, the main filter ring comprises a plurality of uniformly distributed fixing columns, a pair of side walls of the fixing columns are respectively provided with a row of spraying holes, and the spraying holes are communicated with the sealing rings. A filter column is connected between every two adjacent fixing columns, floating columns are slidably connected into the fixing columns, inner filter cylinders matched with the main filter ring are connected between the multiple floating columns, an outer filter ring matched with the main filter ring is connected between the outer walls of the pair of sealing rings, and multiple pairs of inflation expansion columns matched with the inner filter cylinders are connected between the pair of sealing rings. According to the scheme, in the using process, the inner filter cylinder is desorbed by controlling floating of the floating column, impurities intercepted between the filter columns and the floating column are intermittently collected in the floating process of the floating column, and impurity accumulation between the filter columns and the floating column is reduced.

Description

technical field [0001] The invention relates to the field of filter elements, in particular to an anti-clogging composite filter element. Background technique [0002] Filter element is a professional term for filtration and purification functions. In order to purify the resources of the original fluid and a simple device for separating resources, the filter element is now mainly used in oil filtration, air filtration, water filtration and other filtration industries. The filter element separates solid particles in liquid or gas, or makes different material components fully contact, speeding up the reaction time, which can protect the normal operation of the equipment or the cleanliness of the air. When the fluid enters the filter element with a certain size filter, its impurities are blocked. , while the clean stream flows out through the filter element. The liquid filter element makes the liquid (including oil, water, etc.) clean the contaminated liquid to the state requi...

Problems solved by technology

[0003] Existing filters are usually made of multi-layer filter screens laid layer by layer, and the feed liquid passes through the filter layers with different pore sizes to complete the filtration. In this filtering method, the contact area between the filter layer and the feed liquid is limited, resulting in high filtration resistance. Moreover, the filtered impurities adhere to the filter layer and are difficult to clean
