A self-cleaning multi-stage combined environmental protection filter device

Abstract

The invention relates to a self-cleaning multi-segment combined type environmentally friendly filtering device. The self-cleaning multi-segment combined type environmentally friendly filtering deviceis designed by using a brand new modular combination structure, various segments of water purifying devices are combined and uniformly controlled by a master control module (20) to purify water and self-clean, wherein the various segments of water purifying devices are mutually separated on the basis of disconnection of various main electric control valves (16), water in a purified area (22) in each water purifying device is introduced to a corresponding water storage cabin (3), the clean water in the water storage cabin (3) is used to clean a filter film body (2) in a corresponding main pipeline (1) through a water spray nozzle device (9) in combination with the operation of gas injection of a corresponding gas pump (4), the filtering and flowing direction of the water flow is taken intoconsideration in the cleaning process, then the filter film body (2) is accurately cleaned, the cleaning water is discharged to a sewer pipeline (18) to finish the self-cleaning operation, a filter cartridge is efficiently self-cleaned, and the service life of the filter cartridge is prolonged.

Description

technical field [0001] The invention relates to a self-cleaning multi-section combined environmental protection filter device, which belongs to the technical field of water purification equipment. Background technique [0002] With the continuous development of production technology, water quality issues have gradually become the focus of daily life. The emergence of water purifiers is undoubtedly an inevitable social development. [0003] Water purifiers are also called water purifiers and water quality purifiers. They are water treatment equipment that perform deep filtration and purification of water quality according to the requirements for water use. The core of its technology is the filter membrane in the filter element device. At present, the main technology comes from ultrafiltration membrane and RO reverse osmosis membrane. The water purifier can effectively filter out rust, sand, colloid and other chemicals such as residual chlorine, smell, color, and pesticides i...

Problems solved by technology

[0004] Existing water purifiers are equipped with various types of filter elements for step-by-step filtration of water quality. As we all know, filter elements have a lifespan. Even when they have been used for a long time, they need to be replaced. But this is inevitable for existing water purifiers, and to truly achieve replacement-free and operation-free, more research and development and efforts are needed in water purification, but in terms of filter use, we can also extend the filter The method of service life, reducing operation and replacement, is an optional method, but this method also requires the efforts of technicians
