Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a cylindrical filter with a V-shaped structure. Background Art

[0002] Cylindrical filters are widely used in engine air intake filtration, industrial dust removal, gas turbine air intake filtration and other fields. Cylindrical filters are composed of filter material pleats, upper and lower end covers, inner and outer metal guards and polyurethane sealants. The filter material pleats are installed between the inner and outer metal guards, and then bonded and fixed to the upper and lower end covers by polyurethane sealants to form a cylindrical filter. Filter materials of different materials, such as wood pulp filter materials, polyester filter materials, membrane materials, or their combinations can be made into cylindrical filters. At the same time, the filter materials after pleating can greatly increase the filter area of ​​the cylindrical filter.

[0003] The selection of filter materials for traditional cylindrical filters often focuses on wood pulp fiber materials and polyester materials. Synthetic fiber materials and glass fiber materials cannot be used as filter materials for traditional cylindrical filters due to stiffness and strength reasons.

[0004] Traditional cylindrical filters use inner and outer iron meshes to support the filter. During the use of the filter, the pleat tips of the filter material inevitably rub against the iron meshes, causing the filter material to wear and resulting in reduced filter performance.

[0005] Currently, there are many patents that optimize cylindrical filters to improve the performance of cylindrical filters. For example, Chinese patent CN216537493U describes a cylindrical filter made of concave-convex filter material. By adjusting the thickness, arrangement and spacing of the concave and convex patterns, the performance of the cylindrical filter can be optimized. Chinese patent CN219517975U designs a replaceable filter cartridge cylindrical filter. This design of detachable components can only replace the filter cartridge after use, while retaining other filter components. The technology described in the existing patents is generally based on the structure of the cylindrical filter remaining unchanged, and the filter material and filter components are optimized to improve the performance of the filter. The present invention aims to develop a cylindrical filter that does not require adjustment of the existing filter assembly structure, can be used with a wider variety of filter materials and has a more stable structure.

[0006] In order to solve the above technical problems, the purpose of the utility model is to provide a cylindrical filter with a V-shaped structure; the filter does not need to adjust the existing filter assembly structure and can be directly installed in a filter assembly that matches the traditional cylindrical filter. The filter can use a wider variety of filter materials, which can greatly expand the filter's filtering accuracy range and can be applied to more working conditions. The filter also has high structural stability and performance stability.

[0007] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0008] A cylindrical filter with a V-shaped structure comprises a filter body, wherein the filter body comprises a plurality of filter blocks, a plurality of frame members and a plurality of splicing members, wherein every two filter blocks are spliced ​​into a V-shaped filter pleat through the splicing members, and the plurality of spliced ​​V-shaped filter pleats are spliced ​​together in sequence through the frame members to form the filter body.

[0009] Furthermore, the filter block is a rectangular block.

[0010] Furthermore, the number of filter blocks is 12, and every two filter blocks are spliced ​​into a V-shaped filter pleat block with an inner angle of 120°.

[0011] Furthermore, the splicing piece is bonded between the two filter blocks by polyurethane sealant.

[0012] Furthermore, the splicing angle between every two V-shaped filter pleats is 60°.

[0013] Furthermore, every two V-shaped filter blocks are spliced ​​together through two frame members.

[0014] Furthermore, the outer side of each frame member is an arc-shaped structure, so that the filter body formed after splicing has a cylindrical outer contour.

[0015] Furthermore, the filter block is made of wood pulp fiber material, polyester material, synthetic fiber material or glass fiber material.

[0016] Based on the structure of the utility model, the selection of filter materials is more abundant, and the filtering precision range of the filter is also greatly expanded, so that corresponding filter materials can be selected according to different filtering application conditions.

[0017] Furthermore, it comprises an upper end cover and a lower end cover, wherein the upper end cover is connected to the upper end of the filter body, and the lower end cover is connected to the lower end of the filter body.

[0020] 1. The cylindrical filter of the utility model can be directly installed in the filter assembly matching the traditional cylindrical filter, without the need to redesign the filter assembly and the filter connection joint;

[0021] 2. The filter structure of the utility model is formed by splicing filter blocks, splicing parts and frame parts. On the basis of a relatively stable structure, the filter block has a richer material selection, which greatly expands the filter accuracy range of the filter, so that the corresponding filter material can be selected for different filtering application conditions; compared with the traditional cylindrical filter, the filter material selection is often concentrated on wood pulp fiber materials and polyester materials, the filter material of the utility model can also select synthetic fiber materials and glass fiber materials;

[0022] 3. The filter of the utility model utilizes a skeleton member and a splicing member to splice the filter block into a whole. The arrangement of the skeleton member and the splicing member makes the entire structure more stable. Moreover, the splicing of the filter block in the skeleton member and the splicing member can also avoid contact and friction between the filter block and other components, thereby ensuring the stable performance of the filter.
