Filter element self-cleaning system and method

Abstract

The invention relates to a filter element self-cleaning system which comprises a cylindrical filter membrane, a water inlet sleeve which sleeves the periphery of the filter membrane, an upper cover and a lower cover. A water inlet hole corresponding to the water inlet sleeve and a water outlet hole corresponding to an inner hole of the filter membrane are formed in the upper cover. A mounting cavity is formed in the lower cover, and an air chamber, a pressurizing assembly for pressurizing air in the mounting cavity, a steel wire rope and a winding and unwinding assembly matched with the steel wire rope are arranged in the mounting cavity. The inner wall of the water inlet sleeve is longitudinally and slidably connected with an air injection ring, the air injection ring sleeves the filter membrane, a plurality of obliquely downward air injection holes facing the outer side surface of the filter membrane are formed in the inner wall, and the air injection ring is connected with the air chamber through an air pipe and is supplied with air by the air chamber. The air injection ring is connected with the steel wire rope. An electric control water outlet valve is arranged on the lower cover. Through the mode of spraying high-pressure gas, the cleaning strength is high, and dead angles are few. Meanwhile, lifting reciprocating cleaning can be achieved, the overall structure is reasonable and quite compact, and the cleaning effect is good.

Description

technical field [0001] The invention relates to the technical field of filter elements, and more specifically, to a filter element self-cleaning system and method. Background technique [0002] The self-cleaning of the filter element is used to automatically clean the filter element. At present, most of the methods used are backwash self-cleaning methods. This method has a big defect that the cleaning strength is insufficient, and it cannot effectively clean the attachments on the outer surface. Cleaning requires a filter element self-cleaning system and method that can solve the above problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a filter element self-cleaning system and method for the above-mentioned defects of the prior art. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] Construct a filter self-cleaning system, including a cylindrical...
