[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5As shown, this utility model embodiment provides a composite high-efficiency filtration device for PTFE fiber filter bag raw materials, including an upper fixed plate 1, a limiting post 2 fixedly connected to the bottom of the upper fixed plate 1, a lower fixed plate 3 fixedly connected to the bottom of the limiting post 2, a composite filtration mechanism 4 provided on the surface of the limiting post 2, the composite filtration mechanism 4 including an adsorption filter material block 41, an upper top cover 42, a positioning block 43, a filter assembly 44, a groove 45, and a limiting block 46. The adsorption filter material block 41 is disposed inside the limiting post 2, the upper top cover 42 is disposed on the top of the upper fixed plate 1, the positioning block 43 is fixedly connected to the bottom of the upper top cover 42, the filter assembly 44 is wound around the surface of the limiting post 2, the groove 45 is formed on the surfaces of the upper fixed plate 1 and the lower fixed plate 3, and the limiting block 46 is fixedly connected to the right side of the filter assembly 44. The filter assembly 44, which is snapped into the inside of the groove 45, includes a filter screen 441, a base fabric layer 442, a PTFE fiber layer 443, a protective layer 444, nanofibers 445, and a meltblown fabric 446. The filter screen 441 is wrapped around the surface of the limiting post 2. The base fabric layer 442 is fixedly connected to the rear side of the inner wall of the filter screen 441. The PTFE fiber layer 443 is fixedly connected to the front side of the base fabric layer 442. The protective layer 444 is fixedly connected to the front side of the PTFE fiber layer 443. The nanofibers 445 are fixedly connected to the front side of the protective layer 444. The meltblown fabric 446 is fixedly connected to the front side of the nanofibers 445. A connecting membrane 47 is fixedly connected to the left side of the front side of the filter assembly 44. A first Velcro 48 is fixedly connected to the left side of the front side of the connecting membrane 47. A second Velcro 49 is provided on the right side of the front side of the connecting membrane 47.

[0030] With the composite filtration mechanism 4 in place, the adsorption filter media block 41 and the filter assembly 44 perform filtration and adsorption. The filter assembly 44, groove 45 and limiting block 46 cooperate to quickly fix the filter assembly 44, thereby ensuring that the filter assembly 44 can be replaced quickly, preventing the overall replacement cost of the filter device from being too high, improving the convenience of replacement and maintenance and extending the service life of the filter device. By using a combination of various materials such as filter screen 441, base cloth layer 442, PTFE fiber layer 443, protective layer 444, nanofiber 445 and meltblown cloth 446 with the adsorption filter media block 41, the combination of these materials enhances the filtration effect and ensures that the device can efficiently remove impurities and pollutants.

[0031] Example 2

[0032] like Figure 1-5As shown, in one embodiment, a handle 5 is fixedly connected to the top of the upper cover 42, and the handle 5 is used in conjunction with the upper cover 42. A folding groove 6 is provided on the top of the connecting membrane 47, and the folding groove 6 is used in conjunction with the connecting membrane 47. An elastic membrane 7 is fixedly connected to the left side of the limiting block 46, and the elastic membrane 7 is fixedly connected to the right side of the filter assembly 44. The elastic membrane 7 is used in conjunction with the limiting block 46. A filling sponge 8 is fixedly connected inside the nanofiber 445, and the filling sponge 8 is used in conjunction with the nanofiber 445. A friction pad 9 is fixedly connected to the surface of the positioning block 43, and the friction pad 9 is rubbed in conjunction with the groove of the upper fixing plate 1.

[0033] The handle 5 allows users to pull the top cover 42 more easily, improving user comfort. The folding groove 6 allows the connecting membrane 47 to fold more efficiently, preventing the first Velcro 48 and the second Velcro 49 from loosening due to rebound force. The elastic membrane 7 provides a stretching force to the limiting block 46, enabling it to quickly reset. The filling sponge 8 fills the nanofiber 445, preventing it from deforming severely. The friction pad 9 effectively increases the friction between the positioning block 43 and the upper fixing plate 1 groove, improving the stability of the positioning block 43.

[0034] In operation, the user first inserts the adsorption filter media block 41 through the opening of the upper fixing plate 1, where it is positioned by the limiting post 2. The upper top cover 42 is then installed on top of the upper fixing plate 1 via the positioning block 43 and friction pad 9. Next, the connecting membrane 47 is fitted onto the surface of one of the limiting posts 2. The connecting membrane 47 is folded using the folding groove 6, raising the first Velcro 48 and second Velcro 49 to secure it to the surface of the limiting post 2. The filter assembly 44 is then wrapped around the limiting post 2, and the limiting clip 46 is installed into the groove 45 using the elastic membrane 7, thus securing the filter assembly 44 and allowing for quick disassembly. The filter assembly 44 is then disassembled via the filter screen 441, base fabric layer 442, and PTFE fiber. The filter assembly 44, composed of six layers—layer 443, protective layer 444, nanofiber 445, and meltblown fabric 446—works closely with the adsorption filter media block 41 to achieve efficient filtration of the PTFE fiber filter bag material. The filter mesh 441, as the preliminary filtration layer, effectively blocks large particles of impurities. The base fabric layer 442 provides stable support. The PTFE fiber layer 443, with its excellent corrosion resistance, high temperature resistance, and high filtration efficiency, becomes the core of the filtration process. The protective layer 444 further protects the inner structure from damage. The nanofiber 445 and meltblown fabric 446, through their fine fiber structure and efficient adsorption capacity, perform deep filtration of tiny particles. The entire filtration process is fast and efficient, significantly improving the working efficiency of the filtration device.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
