Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter material technology, and in particular to a high-performance composite filter element. Background Technology
[0002] In the existing technology, "composite filter cartridges" usually refer to water treatment components that integrate two or more filter materials with different filtration functions into a single filter cartridge unit through a specific physical method. The core design goal is to achieve multi-stage and multi-effect filtration through a single filter cartridge. For example, PP cotton is used for pre-filtration of particulate matter, and then activated carbon is used to adsorb residual chlorine and organic matter. The structural form is mostly to fix different filter materials in a unified shell by layering, wrapping or sintering, forming a fixed and indivisible whole to achieve comprehensive purification of water quality.
[0003] In existing technologies, the number of filter media sleeves in filter cartridges is usually fixed and cannot be flexibly adjusted according to actual filtration needs. This limits filtration efficiency and system adaptability, resulting in insufficient performance when treating different water qualities or pollutants. At the same time, the ability to adjust the number of filter layers is lacking, and the filtration path cannot be optimized through coaxial nesting design, which affects the realization of gradient filtration effect. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a high-performance composite filter element. Through the design of multiple threaded interfaces, the number of filter media sleeves can be adjusted according to requirements. By coaxially nesting filter media sleeves of different diameters, the number of filter layers can be adjusted, thereby improving the filtration efficiency and adaptability of this invention.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-performance composite filter element, comprising an outer tube, wherein the two ends of the outer tube are respectively threaded and sealed with an end cap one and an end cap two, and a filter material sleeve is provided inside the outer tube; The filter media sleeve includes a double-layer mesh cylinder filled with filter media. Both ends of the double-layer mesh cylinder are provided with threaded rings, and the threaded rings are threadedly connected to end cap rings.
[0006] In a preferred embodiment, the end cap ring and the first end cap, as well as the end cap ring and the second end cap, are all threaded connections.
[0007] In a preferred embodiment, rubber pads are provided between the end cap ring and end cap one, and between the end cap ring and end cap two.
[0008] In a preferred embodiment, a water outlet pipe is sealed and installed on the outer sleeve.
[0009] In a preferred embodiment, a water inlet pipe is sealed at the center of the end cap 2.
[0010] In a preferred embodiment, the double-layer mesh cylinder and the threaded ring are connected by spot welding.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention utilizes a multi-threaded interface design, allowing the number of filter media sleeves to be adjusted according to requirements. By coaxially nesting filter media sleeves of different diameters, the number of filter layers can be adjusted, thereby improving the filtration efficiency and adaptability of this invention. At the same time, the threaded connection design also makes the disassembly and assembly process simple and quick, allowing for rapid replacement or addition of filter media sleeves without the need for complex tools. This not only ensures sealing and structural stability under high pressure, preventing fluid leakage and contamination, but also significantly reduces maintenance time and costs, enhancing overall durability and high-performance filtration capabilities.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0020] like Figures 1 to 6 As shown, this utility model provides a technical solution: a high-performance composite filter element, including an outer tube 1, with end cap 2 and end cap 3 respectively threaded and sealed at both ends of the outer tube 1, a filter material sleeve 6 inside the outer tube 1, an outlet pipe 5 sealed on the outer tube 1, and an inlet pipe 4 sealed at the center of the end cap 3. In the above description, the two ends of the outer tube 1 are connected by threaded sealing end cap 2 and end cap 3, so that the inside of the outer tube 1 forms a sealed space to prevent leakage. The filter media sleeve 6 is installed inside the outer tube 1 as the core of filtration. Water flows in from the inlet pipe 4, which is sealed and installed in the center of the end cap 3. After being filtered by the filter media sleeve 6, the filtered water flows out from the outlet pipe 5, which is sealed and installed on the outer tube 1. This design achieves stable fluid treatment and prevents external contamination from entering. At the same time, the threaded connection facilitates disassembly and maintenance, improving overall durability and filtration efficiency. The filter media sleeve 6 includes a double-layer mesh cylinder 61 filled with filter media. Both ends of the double-layer mesh cylinder 61 are provided with threaded rings 62. The double-layer mesh cylinder 61 and the threaded rings 62 are connected by spot welding. The threaded rings 62 are threadedly connected to end cap rings 63. In this design, the double-layer mesh cylinder 61 and end cap rings 63 are modularly assembled by the threaded rings 62, so that the filter media sleeve 6 is detachable as a whole, and the filter media in the double-layer mesh cylinder 61 can be replaced. The threaded connection simplifies the disassembly process and enhances the overall durability and ease of operation. Furthermore, the end cap ring 63 and the end cap one 2 and the end cap ring 63 and the end cap two 3 are both threaded connections, and rubber pads 7 are provided between the end cap ring 63 and the end cap one 2 and the end cap ring 63 and the end cap two 3. In the above, the design of threaded connection between end cap ring 63 and end cap 1 2 and between end cap ring 63 and end cap 2 3 creates a detachable rigid connection frame, ensuring the stability and assembly accuracy of the overall structure. At the same time, rubber pads 7 are set at each connection interface. The threads provide mechanical fastening force, and the rubber pads 7 undergo elastic deformation under this fastening force to fill the micro gaps between the metal parts, thereby achieving a double sealing effect. In addition, there are four sets of filter media sleeves 6, each with a different diameter, and the four sets of filter media sleeves 6 are coaxially nested.
[0021] In this embodiment, the modular quick-release and adjustable effect is achieved based on its fully threaded connection design. The outer sleeve 1 can form a rigid sealed container by connecting the end cap 2 and the end cap 3 through threaded sealing. The inner filter material sleeve 6 can ensure the stability of the filter material by spot welding the double-layer mesh cylinder 61 to the threaded ring 62. The threaded connection between the threaded ring 62 and the end cap ring 63 realizes the modular assembly of the filter material sleeve 6, providing physical structural support for the filling and positioning of the filter material. Furthermore, the end cap ring 63 connects to the end cap 2 and the end cap 3 through threads to position and seal each filter material sleeve 6, while the rubber gasket 7 is used to enhance the seal.
[0022] Working principle: like Figures 1 to 6 As shown, in use, fluid is injected through the inlet pipe 4, which is sealed and installed at the center of the end cap 2 3, and enters the sealed pressure vessel formed by the outer sleeve 1 and the end cap 1 2 and end cap 2 3 through a threaded seal connection. Then, under the drive of water pressure, the fluid passes through multiple sets of filter media sleeves 6 of different diameters arranged coaxially inside. Each filter media sleeve 6 is filled with filter media by a double-layer mesh cylinder 61, and is modularly threadedly connected to the end cap ring 63 through the threaded rings 62 at both ends of the double-layer mesh cylinder 61. The end cap ring 63 is then fastened to the end cap 1 2 and end cap 2 3 through threads, and elastic sealing is achieved at each interface using rubber gaskets 7. This fully threaded stacked structure design forms a customizable, multi-stage series precision filtration channel. Finally, the purified fluid is discharged from the outlet pipe 5, which is sealed and installed on the outer sleeve 1. This invention utilizes a coaxial multi-stage filter media sleeve 6 design to enable gradient filtration of different pollutants, significantly improving filtration accuracy and dirt-holding capacity. Simultaneously, the fully threaded connection design provides excellent sealing and pressure resistance, effectively preventing leakage and ensuring fluid purity. Furthermore, this design ensures excellent maintenance convenience and adaptability; users can quickly unscrew end caps 2 and 3 without special tools, and add, remove, or replace any level of filter media sleeve 6 according to actual water treatment needs, thereby significantly reducing maintenance costs and allowing a single product platform to adapt to diverse application scenarios by replacing internal modules. Furthermore, in use, this invention allows for the following: the innermost first filter media sleeve 6 can be filled with granular activated carbon or carbon fiber felt, utilizing the highly efficient adsorption capacity of activated carbon to remove residual chlorine, discoloration, odor, and some organic pollutants from the water immediately, thus protecting all outer filter media from oxidative damage caused by chlorine; the second filter media sleeve 6 adjacent to the first layer can be filled with ion exchange resin, effectively removing calcium and magnesium ions from the water through ion exchange reactions to reduce hardness or selectively adsorbing heavy metal ions; the third filter media sleeve 6 adjacent to the second layer can use an ultrafiltration membrane or... Nanofiltration membranes efficiently trap colloids, bacteria, viruses, and even smaller ions that the first two stages failed to remove completely, deeply purifying the water. The outermost fourth filter media sleeve 6 can be filled with PP meltblown cotton or similar high dirt-holding capacity filter media, serving as the final safety barrier and protective layer. It captures tiny particles that may be generated during installation and maintenance, as well as trace amounts of suspended solids remaining in the water after membrane filtration, ensuring clear effluent. At the same time, since the fourth filter media sleeve 6 is located on the outermost side and is relatively inexpensive, prioritizing the replacement of this layer during maintenance can also protect the more expensive filter cartridges inside to some extent.
[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
