Abstract
Description
Technical Field
[0001] This application relates to liquid filter cartridges, and more particularly to anti-clogging fluorine filter cartridges. Background Technology
[0002] In industrial production and fluid treatment, anti-clogging fluoropolymer filter cartridges are widely used for filtering and separating impurities in fluids. For example, PFA pleated filter cartridges are made of PFA plastic, which is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. The main functions of PFA pleated filter cartridges are acid and alkali resistance, corrosion resistance, high temperature resistance, and oxidation resistance.
[0003] A search revealed Chinese patent publication number CN219518110U, which discloses a filter element comprising a filter element skeleton and filter wire wound on the filter element skeleton. An upper embedding ring is fixedly connected to the upper outer end of the filter element skeleton, and a lower embedding ring is fixedly connected to the lower outer end of the filter element skeleton. The starting end of the filter wire is welded to the upper embedding ring, and the end of the filter wire is welded to the lower embedding ring. The upper and lower embedding rings enable efficient, simple, and convenient welding of the filter wire, thereby improving the service life of the filter element.
[0004] Although the aforementioned patent achieves efficient, simple, and convenient welding of the filter wire by welding the starting end of the filter wire to the upper embedding ring and the ending end to the lower embedding ring during the winding and fixing process, this method allows for welding and fixing of the filter wire in a relatively simple way, regardless of its thickness. Furthermore, it facilitates disassembly of the filter wire during subsequent replacement, such as using a kerf to remove the welded area. However, during use, the fluorinated filter element cannot reduce clogging through multi-layer filtration, leading to a decrease in service life and stability. Therefore, an anti-clogging fluorinated filter element is proposed to address these issues. Utility Model Content

[0033] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.
[0034] Example 1: An anti-clogging fluorine filter element, referring to... Figures 1 to 3 The filter element includes a porous skeleton 1, which serves as the basic support structure for the entire filter element, ensuring its overall stability and strength. End caps 2 are fixedly connected to the upper and lower sides of the porous skeleton 1, providing sealing and fixation to ensure the structural integrity and airtightness of the filter element. A filter element mechanism 4 is fixedly connected to the top of one of the end caps 2. The filter element mechanism 4, as the main filtration part of the filter element, achieves efficient filtration of impurities in the fluid through a multi-layer filtration structure. The filter element mechanism 4 includes a porous skeleton 41, which serves as the support for the filter element mechanism 4. A support structure is fixed to the top of one of the end caps 2 to ensure the stability of the filter element mechanism 4. The top of the porous skeleton 41 is fixedly connected to the top of one of the end caps 2. A flow guide layer 42 is fixedly connected to the outside of the filter element mechanism 4. The flow guide layer 42 is fixed to the outside of the filter element mechanism 4 and plays the role of guiding the flow of fluid, so that the fluid can pass through the filter membrane 43 evenly and reduce the blockage caused by excessive local flow velocity. A filter mechanism 5 is fixedly connected to the bottom of one of the end caps 2 to further filter impurities in the fluid. At the same time, the anti-clogging ability and service life of the filter element are improved through the conical structure and the protective reinforcement component 53.
[0035] Specifically, when the fluid to be filtered enters the anti-clogging fluorine filter element, it first comes into contact with the filter mechanism 5 fixed at the bottom of the end cap 2. Its conical structure initially intercepts larger impurities in the fluid. Subsequently, the fluid passes through the porous skeleton 1 and enters the filter element mechanism 4 fixed at the top of the end cap 2. The porous skeleton 41 in this mechanism provides support for the multi-layer filtration structure. Under the guidance of the flow guide layer 42, the fluid passes evenly through the multi-layer filtration structure, and impurities are further filtered and intercepted. The fluid filtered by the filter element mechanism 4 passes through the porous skeleton 1 again and finally flows out of the filter element through the other end cap 2.
[0036] The filtration mechanism 5 includes a guide channel filter column 51, which is used for preliminary filtration of impurities in the fluid. The upper and lower sides of the guide channel filter column 51 are fixedly connected to the bottom of one end cap 2. A conical filter column 52 is fixedly connected to the bottom of one end cap 2. The conical filter column 52 supports and protects the filter membrane 43. At the same time, the conical structure helps to reduce the impact of the fluid on the filter membrane 43 and reduce the risk of clogging. A protective reinforcement component 53 is fixedly connected to the outside of the conical filter column 52. 53 includes a rubber protective column 5302, which prevents the filter element from being damaged by mechanical impact during use. The top of the rubber protective column 5302 is fixedly connected to the bottom of one of the end caps 2. A reinforcing layer 5301 is fixedly connected to the outside of the rubber protective column 5302. The reinforcing layer 5301 further enhances the structural strength of the filter element and prevents the filter element from deforming under high pressure and high flow. An adsorption mechanism 7 is fixedly connected to the bottom inner side of the porous skeleton 1, and a cleaning mechanism 6 is fixedly connected to the top inner side of one of the end caps 2.
[0037] Specifically, the fluid to be filtered first flows into the guide groove filter column 51 at the bottom of the end cover 2, where larger impurities are initially filtered out. Then, it undergoes secondary filtration through the conical filter column 52, and then passes through the adsorption mechanism 7 on the inner side of the bottom of the porous skeleton 1 to further adsorb residual impurities. After that, the fluid enters the filter element mechanism 4 upwards and undergoes fine filtration in the multi-layer filtration structure supported by the porous skeleton 41. At the same time, the guide layer 42 guides the fluid to pass evenly through the filter membrane 43. Before the filtered fluid flows out through the end cover 2, if it is necessary to clean the filter element, the cleaning mechanism 6 inside the top side of the end cover 2 can be activated to flush the filter element mechanism 4 and the filtration mechanism 5, ensuring the continuous operation of the filter element.
[0038] Reference Figures 4 to 6The cleaning mechanism 6 includes two control valves 62. Through the control valves 62 and connecting water pipes 61, periodic reverse cleaning of the filter element is achieved, extending the filter element's service life and improving filtration efficiency. The control valves 62 are externally fixedly connected to the inside of one of the end caps 2. The output end of the control valves 62 is fixedly connected to the connecting water pipes 61, which are used to transport cleaning water. The design of the connecting water pipes 61 ensures that the water flow is evenly distributed, improving the cleaning effect. The adsorption mechanism 7 includes two fixed columns 72. Magnetic blocks 71 adsorb ferromagnetic impurities in the fluid, further improving the filtration effect and reducing impurity clogging of the filter element. The bottom of the filter element is fixedly connected to the inner bottom of the porous frame 1, and is fixed to the inner bottom of the porous frame 1 to support the magnetic block 71, ensuring its stability and accurate position. The top of the fixed column 72 is fixedly connected to the magnetic block 71, which has strong magnetism and can effectively adsorb ferromagnetic metal impurities in the fluid. The bottom of the porous frame 1 is fixedly connected to the connection port 3, which serves as a connection component between the filter element and other pipeline systems, ensuring that the filter element can be smoothly installed into the filtration system. The sliding connection of the connection port 3 has two sealing rings 73, which are installed at the sliding connection of the connection port 3 to ensure the sealing of the connection port 3 and prevent fluid leakage.
[0039] Specifically, when fluid flows into the filter element from the pipeline system, it first enters the porous skeleton 1 through the connection port 3. At this time, ferromagnetic impurities in the fluid are adsorbed by the magnetic block 71 fixed on the top of the fixed column 72, thus initially purifying the fluid. Then, the fluid is further filtered through the filter layer of the filter element to remove non-ferromagnetic impurities. During the filtration process, impurities will gradually accumulate in the filter element, leading to a decrease in filtration efficiency. In order to extend the service life of the filter element, the system will periodically start the reverse cleaning program. During cleaning, the two control valves 62 will open according to the preset program, allowing cleaning water to enter the filter element through the connecting water pipe 61. The design of the connecting water pipe 61 ensures that the cleaning water can be evenly distributed to thoroughly clean the filter element. The cleaning water carrying impurities is discharged from the filter element through the connection port 3, completing the reverse cleaning process. The sealing ring 73 ensures the sealing of the connection port 3 to prevent fluid leakage.
[0040] Reference Figure 1 and Figure 7 A filter membrane 43 is fixedly connected to the outside of the flow channel filter column 51. It is the core component for realizing the filtration function. The filter membrane 43 uses high-precision filter material, which can effectively intercept small particles and impurities in the fluid. A support layer 44 is fixedly connected to the outside of the cone-shaped filter column 52. The top of the flow channel layer 42 and the top of the filter membrane 43 are fixedly connected to the bottom of one of the end caps 2. The top of the protective reinforcement component 53 and the top of the reinforcement layer 5301 are fixedly connected to the top of one of the end caps 2.
[0041] Specifically, the fluid first enters the device and contacts the first filter column 51 of the flow guide channel. The high-precision filter membrane 43 fixedly connected to its exterior begins to function, effectively intercepting tiny particles and impurities in the fluid. Subsequently, the fluid, after preliminary filtration, flows to the second cone-shaped filter column 52. The external support layer 44 helps maintain the stability of the filtration structure. At the same time, the flow guide layer 42 evenly guides the fluid to the filter membrane 43 to ensure the filtration effect. Finally, the fluid, after being fully filtered by the filter membrane 43, completes the entire filtration process with the cooperation of the end cap 2 and is discharged from the device.
[0042] The implementation principle of this application embodiment is as follows: First, during the use of the filter element, the flow guiding layer 42 is placed at the bottom of the top end cap 2. The flow guiding layer 42 further improves the fluidity and filtration efficiency of the liquid. At the bottom of the top end cap 2, the flow guiding groove filter column 51 and the conical filter column 52 cooperate with each other, and the filter membrane 43 also performs filtration, which can effectively reduce the clogging of the filter element during use. The use of the reinforcing layer 5301 and the rubber protective column 5302, supported internally by the porous skeleton 1 and the porous skeleton 41, can better protect and enhance the stability of the filter element during use, effectively prevent large particles from entering the filter element, improve filtration accuracy, and extend the service life of the filter element.
[0043] Meanwhile, the top end cap 2 has a control valve 62 inside, which connects to the water pipe 61 to the external water pipe to backwash the inside, thereby cleaning the inside and effectively removing impurities and contaminants accumulated inside the filter element, thus keeping the filter element clean and maintaining high-efficiency filtration performance. At the bottom, there is a fixing column 72 to support the magnetic block 71, so that when the liquid is filtered, the gold material is adsorbed on the top of the magnetic block 71, which can not only efficiently remove metal impurities in the liquid, but also further improve the purity of filtration.
[0044] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
