Description

Technical Field

[0001] This utility model relates to the field of liquid media filtration technology, and in particular to a split-type clean filter structure. Background Technology

[0002] In the liquid filtration industry (including water treatment, chemical, food and beverage, pharmaceutical, and petrochemical industries), filter screens are a very important core component that is frequently used to achieve clean and reusable filtration. They play a crucial role in filtration equipment by intercepting impurities, separating particles, and purifying the medium, and are used in many continuous or semi-continuous filtration systems.

[0003] Currently, the filter screen and the frame that holds the mesh are usually made as a single unit. There are two methods for fixing the mesh: one is to glue the mesh to the frame, and the other is to injection mold the frame onto it during production. With this existing integrated mesh and frame structure, once the filter screen is damaged, it cannot be repaired or replaced separately; the entire frame must be replaced, leading to material waste and increased operating costs. In large-scale industrial applications, consumable costs and waste volume increase significantly, which is inconsistent with environmental protection and sustainability trends. Therefore, further improvements are needed. Utility Model Content

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] In the description of the utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0021] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] Example 1: As shown in the figure, the present invention includes an outer frame and a filter cotton 4 detachably connected to the outer frame. The filter cotton 4 has a serrated folded surface structure. When the filter cotton 4 is installed in the outer frame, the outer frame can fix and support the filter cotton 4.

[0023] The external frame includes an upper shell 1, a lower shell 2, and a positioning structure. The upper shell 1 and the lower shell 2 are detachably connected. In this example, the upper shell 1 and the lower shell 2 are preferably, but not limited to, connected by a snap-fit ​​mechanism. The snap-fit ​​connection method adopts the common plastic snap-fit ​​connection principle in the prior art, and therefore will not be elaborated in this application. The upper shell 1 and the lower shell 2 are detachably connected by a snap-fit ​​mechanism, allowing the user to easily disassemble and replace the serrated pleated filter cotton 4 in the middle.

[0024] Furthermore, the positioning structure is used to fix and support the filter cotton 4. When the upper shell 1 and the lower shell 2 are engaged, the positioning structure in the outer frame fixes and supports the filter cotton 4. Specifically, the positioning structure can fix both sides of the filter cotton 4 and / or support the middle of the filter cotton 4. The sawtooth-shaped side fixing part 3 and the middle support plate 5 work together to ensure the stable installation and balanced force of the filter cotton 4.

[0025] Example 2: Based on Example 1 above, preferably, the positioning structure includes a side fixing part 3 located on the side of the upper shell 1 and the lower shell 2. The side fixing part 3 is a serrated structure adapted to the shape of the filter cotton 4. When the upper shell 1 and the lower shell 2 are fastened together, the side fixing part 3 with the serrated structure clamps and fixes the side of the filter cotton 4 to prevent the filter cotton 4 from shifting or deforming under the impact of liquid flow, thus ensuring the stability of the filtration effect.

[0026] Meanwhile, the positioning structure also includes a support portion located on the upper housing 1 and / or the lower housing 2. When the upper housing 1 and the lower housing 2 are engaged, the support portion supports the middle part of the filter cotton 4. Specifically, the support portion includes multiple rows of support plates 5 distributed on the upper housing 1 and / or the lower housing 2. In this example, the support plates 5 are fixedly connected between the side fixing portions 3 on both sides. When the upper housing 1 and the lower housing 2 are engaged, the ends of the support plates 5 contact the tips of the serrated folded surface structure of the filter cotton 4. In addition, a connecting frame 6 can be added to the upper housing 1 and / or the lower housing 2. The connecting frame 6 is fixedly connected to each support plate 5 to improve the connection stability of each support plate 5. By setting the support portion, not only can the support for the middle part of the filter cotton 4 be enhanced, preventing dents or collapses caused by liquid pressure differences, but it can also ensure that the filter assembly is subjected to more uniform force, avoiding premature damage due to local stress concentration.

[0027] In summary, this application achieves convenient replacement of the filter cotton by setting a relatively interlocking external frame and utilizing the serrated side fixing parts and the central support plate. This effectively extends the service life of the filter assembly, reduces maintenance and replacement costs, minimizes resource waste, aligns with green environmental protection trends, and lowers long-term operating costs for enterprises or users. Simultaneously, the serrated side fixing parts clamp and fix the sides of the filter cotton, preventing displacement or deformation under the impact of liquid flow. The support part not only enhances the support in the middle of the filter cotton, preventing dents or collapses due to liquid pressure differences, but also maintains the uniform unfolding of the folded shape, improving filtration efficiency.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
