Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a multi-layer braided filter element. Background Art

[0002] With the acceleration of industrialization and the improvement of environmental awareness, water treatment technology, especially drinking water purification, has received unprecedented attention. As the core component of the water treatment system, the performance of the filter element directly affects the effect and efficiency of water purification. Traditional filter element designs mostly use single-function materials, such as activated carbon filter elements that focus on adsorbing organic matter and improving taste, while microporous filter membranes focus on removing particulate matter. However, single-function filter elements often find it difficult to meet the increasingly stringent requirements for water purification, especially in terms of removing microbial contamination, chemical residues, and improving water taste.

[0003] To this end, the present application proposes a multi-layer woven filter element that can achieve multiple functions. Utility Model Content

[0004] In view of the deficiencies in the background technology, the utility model provides a multi-layer braided filter element.

[0005] The technical solution adopted by the utility model is: a multi-layer woven filter element, comprising two cover plates and a plurality of filter element tubes arranged between the two cover plates, the filter element tube comprising two clamping plates, a first winding plate, a second winding plate, a third winding plate, a filtration layer wound outside the first winding plate, an adsorption layer wound outside the second winding plate and a sterilization layer wound outside the first winding plate, the first winding plate, the second winding plate and the third winding plate are all fixed between the two clamping plates in the form of a circumferential array, and liquid gaps are left between adjacent first winding plates and first winding plates, between adjacent second winding plates and second winding plates, and between adjacent third winding plates and third winding plates.

[0006] Furthermore, a plurality of liquid holes are provided on the first winding plate, the second winding plate and the third winding plate.

[0007] Furthermore, the filtration layer is a multi-layer stacked submicron non-woven fabric layer, the adsorption layer is a multi-layer stacked activated carbon fiber fabric layer, and the sterilization layer is a multi-layer stacked sterilization non-woven fabric layer.

[0008] Furthermore, the clamping plate is provided with a positioning column, and the cover plate is provided with a positioning hole matched with the positioning column.

[0009] Furthermore, the positioning column includes a convex column integrally formed with the pressed step and a rubber sleeve sleeved on the convex column.

[0010] Furthermore, the clamping plate is provided with an external threaded tube, which passes through the mounting hole on the cover plate and is locked by a nut.

[0011] The beneficial effects of the utility model are:

[0012] 1. Efficient integrated purification function: This application effectively intercepts large particles of impurities through the filtration layer outside the first winding plate, and the adsorption layer outside the second winding plate strongly adsorbs organic matter, chemical residues and odors, while the sterilization layer wrapped outside the first winding plate can effectively kill microorganisms in the water to ensure water quality safety. This multi-level, multi-functional integrated design realizes all-round water quality treatment from physical filtration to chemical adsorption to biological purification, significantly improving purification efficiency and water quality standards.

[0013] 2. Optimize fluid dynamics performance: The specially designed liquid gap between adjacent winding plates effectively reduces water flow resistance and maintains low pressure loss even at high flow rates, ensuring efficient and stable operation of the water treatment system, extending the service life of the filter element and reducing energy consumption.

[0014] 3. Simplify structure and reduce costs: The structural design of this application includes multi-layer purification functions. Through the clever layout of plywood and wrapping plates, the overall structure is compact and easy to assemble, which reduces production complexity and costs, and is also convenient for users to replace and maintain later, thereby improving the market competitiveness of the product.

[0015] 4. Enhance the synergy between materials: Each layer of the winding plate and the functional layers thereon are scientifically configured to not only maximize their own effectiveness, but also promote each other. For example, the filtration layer effectively pre-treats the water quality, creating better working conditions for the subsequent adsorption layer and sterilization layer, thereby maximizing the overall purification efficiency.

[0016] In addition to the objects, features and advantages described above, the present invention has other objects, features and advantages.
