Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration technology, specifically to adsorption filter elements. Background Technology
[0002] An adsorption filter cartridge is a filtration element that uses adsorption to remove impurities, pollutants, or harmful substances from fluids. It is typically made of adsorbent materials with a high specific surface area and abundant microporous structure, most commonly activated carbon, but also including other adsorbents such as molecular sieves, silica gel, and activated alumina. Adsorption filters achieve purification by "capturing" and fixing target pollutants on the surface or inside the pores of the filter material through physical or chemical adsorption. Physical adsorption relies on the material's large specific surface area and porous structure to non-selectively adsorb organic matter, residual chlorine, and odors. Chemical adsorption selectively removes heavy metals and harmful gases through surface modification or loading with specific chemicals. Adsorption filters can be used in household water purifiers, air purifiers, industrial waste gas and wastewater treatment, and in medical and laboratory settings.
[0003] Existing adsorption filter cartridges are not convenient for separating the materials accumulated inside the cartridge during use. If the material is unevenly accumulated, the filter media will move and form channels under the impact of the fluid, allowing the fluid to pass directly through the gaps without fully contacting the adsorption material, thus reducing the contact efficiency and adsorption utilization rate. Moreover, simply filling the filter media will result in low overall mechanical strength of the filter cartridge, making it prone to deformation and displacement under high pressure differential or high flow rate, affecting the stability of the flux. Utility Model Content
[0004] The purpose of this invention is to provide an adsorption filter element with good stability. It solves the problem that existing adsorption filter elements are not easy to separate the material accumulated inside the filter element during use. If the material is unevenly accumulated, the filter material moves under the impact of the fluid and forms a channel, allowing the fluid to pass directly through the gap without fully contacting the adsorption material, thus reducing the contact efficiency and adsorption utilization rate.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adsorption filter element, including a filter element mesh cylinder, a first mounting cover installed at one end of the filter element mesh cylinder, a second mounting cover installed at the other end of the filter element mesh cylinder, the filter element mesh cylinder being filled with filter media, and the first and second mounting covers being detachable from the filter element mesh cylinder to facilitate replacement of the filter media;
[0006] The filter element cylinder has a partition structure installed inside, which separates the filter material and supports the inside of the filter element cylinder.
[0007] As a preferred embodiment of the adsorption filter element of this utility model, the filter element cylinder, the first mounting cover, and the second mounting cover are annular structures, and the outer diameter of the filter element cylinder is the same as that of the first mounting cover and the second mounting cover.
[0008] As a preferred embodiment of the adsorption filter element of this utility model, the connection method between the filter element screen and the first mounting cover is one of bolt connection, threaded connection and interference fit connection.
[0009] As a preferred adsorption filter element of this utility model, the filter material is an inorganic material used for filtering and adsorbing moisture.
[0010] The preferred inorganic material for the adsorption filter element of this utility model is one of the following: activated alumina, zeolite, hydrated iron oxide, diatomaceous earth-based composite filter media, porous ceramic filter element, titanate ion sieve, and hydroxyapatite.
[0011] As a preferred embodiment of the adsorption filter element of this utility model, the separating structure includes a separating ring, which is located at the middle end of the inner cavity of the filter element mesh cylinder and is movably connected to the inner wall of the filter element mesh cylinder.
[0012] As a preferred adsorption filter element of this utility model, the separator ring is provided with several arc-shaped grooves, and the filter material passes through the arc-shaped grooves to enter the bottom of the inner cavity of the filter element screen.
[0013] As a preferred embodiment of the adsorption filter element of this utility model, the separating ring is equipped with a plurality of vertical separating bars, which are distributed circumferentially within the filter element mesh cylinder to separate the filter material inside the filter element mesh cylinder.
[0014] In a preferred embodiment of the adsorption filter element of this utility model, one end of the dividing vertical strip is movably connected to the first mounting cover, and the other end of the dividing vertical strip is movably connected to the second mounting cover, so as to prevent the first mounting cover and the second mounting cover from squeezing the filter element cylinder.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model significantly improves the practicality and reliability of the adsorption filter by setting a detachable installation structure and internal support and partition components in the adsorption filter. Specifically, the first and second installation covers are detachable from the filter screen, which allows users to easily open the filter and replace the internal filter material. It is especially suitable for application scenarios that require regular maintenance or replacement of specific inorganic adsorption materials for different water qualities, greatly reducing the cost of use and improving the ease of operation.
[0017] 2. This utility model, through the setting of a partition structure, not only achieves effective partitioning of the filter media, preventing it from shifting or forming short-circuit channels under fluid impact, but also plays a crucial mechanical support role. The partition ring is located at the middle of the filter element's inner cavity, providing stable support to the middle of the filter element. The two ends of the partition strip are movably connected to the first and second mounting covers, respectively. During filter element assembly or under pressure, it can effectively resist the axial compression of the filter element by the end covers, preventing deformation or damage to the filter element. Simultaneously, the arc-shaped groove on the partition ring ensures the continuity of filter media filling and the unobstructed flow of fluid, ensuring that the fluid passes evenly through the entire filter media layer, thereby improving adsorption efficiency and filtration stability.

[0022] Please see Figures 1-3 The adsorption filter element includes a filter element cylinder 1, a first mounting cover 2 installed at one end of the filter element cylinder 1, a second mounting cover 3 installed at the other end of the filter element cylinder 1, and filter media 4 filled inside the filter element cylinder 1. The first mounting cover 2 and the second mounting cover 3 are detachable from the filter element cylinder 1 to facilitate the replacement of the filter media 4.
[0023] Furthermore, a partition structure 5 is installed inside the filter element cylinder 1. The partition structure 5 separates the filter material 4 and supports the interior of the filter element cylinder 1.
[0024] Furthermore, the filter element cylinder 1, the first mounting cover 2, and the second mounting cover 3 are annular structures, and the outer diameter of the filter element cylinder 1 is the same as that of the first mounting cover 2 and the second mounting cover 3.
[0025] Furthermore, the filter element cylinder 1 and the first mounting cover 2 are connected by one of the following methods: bolt connection, threaded connection, and interference fit connection.
[0026] Furthermore, filter media 4 is an inorganic material used for filtering and absorbing moisture.
[0027] Furthermore, the inorganic material is one of the following: activated alumina, zeolite, hydrated iron oxide, diatomaceous earth-based composite filter media, porous ceramic filter element, titanate ion sieve, and hydroxyapatite.
[0028] Furthermore, the separation structure 5 includes a separation ring 501, which is located at the middle end of the inner cavity of the filter element cylinder 1 and is movably connected to the inner wall of the filter element cylinder 1.
[0029] Furthermore, the separator ring 501 has several arc-shaped grooves 502, through which the filter material 4 passes into the bottom of the inner cavity of the filter element cylinder 1.
[0030] Furthermore, several vertical dividing strips 503 are installed on the dividing ring 501. These vertical dividing strips 503 are distributed around the circumference of the inner cavity of the filter element cylinder 1 to divide the filter material 4 inside the filter element cylinder 1.
[0031] Furthermore, one end of the dividing vertical strip 503 is movably connected to the first mounting cover 2, and the other end of the dividing vertical strip 503 is movably connected to the second mounting cover 3, so as to prevent the first mounting cover 2 and the second mounting cover 3 from squeezing the filter element cylinder 1.
[0032] By incorporating a detachable mounting structure and internal support partition components in the adsorption filter cartridge, the practicality and reliability of the filter cartridge are significantly improved. Specifically, the first mounting cover 2 and the second mounting cover 3 are detachable from the filter cartridge 1, allowing users to easily open the filter cartridge and replace the internal filter media 4. This is especially suitable for application scenarios that require regular maintenance or replacement of specific inorganic adsorption materials for different water qualities, greatly reducing usage costs and improving operational convenience.
[0033] Furthermore, the introduction of the partition structure 5 not only achieves effective partitioning of the filter media 4, preventing it from shifting or forming short-circuit channels under fluid impact, but also plays a crucial mechanical support role. Specifically, the partition ring 501 is located at the middle of the inner cavity of the filter element cylinder 1 to provide stable support for the middle of the filter element cylinder 1. The two ends of the partition vertical strip 503 are movably connected to the first mounting cover 2 and the second mounting cover 3, respectively. When the filter element is assembled or under pressure, it can effectively resist the axial compression of the end cover on the filter element cylinder 1, avoiding deformation or damage to the filter element cylinder 1. At the same time, the arc groove 502 provided on the partition ring 501 ensures the continuity of the filter media 4 filling and the unobstructed flow of fluid channels, ensuring that the fluid passes evenly through the entire filter media layer, thereby improving adsorption efficiency and filtration stability.
[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
