Description

Technical Field

[0001] This utility model relates to the field of filter metal mesh technology, specifically a high-efficiency filter metal mesh. Background Technology

[0002] Metal filters utilize metal mesh, also known as metal mesh filters. The filter element typically consists of multiple layers of corrugated aluminum or stainless steel mesh. The aluminum or stainless steel mesh is formed into a corrugated shape and then overlapped at the correct angles, causing airflow to change direction multiple times as it passes through the mesh. The mesh is arranged with varying densities and pore sizes, from coarse to fine, creating a highly efficient air filter that generates static electricity, achieving low airflow resistance and increasing dust collection capacity and efficiency. Both aluminum and stainless steel filter meshes are safe, robust, and heat-resistant, and are easy to clean and maintain. Long-term use can reduce the overall operating cost of the air filter.

[0003] A high-temperature resistant high-efficiency filter with patent number CN208911675U is configured with an outer frame, a metal mesh and a filter element. The metal mesh and the filter element are installed inside the outer frame. The metal mesh has two sides and the filter element is sandwiched between the two sides of the metal mesh. The filter element is a filter material made of glass fiber filter paper folded into shape.

[0004] However, research has shown that existing high-efficiency filter metal mesh still has the following drawbacks:

[0005] Currently, most commercially available metal filter meshes are fixed using multiple clips or bolts during installation, which is cumbersome. Furthermore, when installing the top part, two workers are required, reducing manpower utilization. Therefore, technological innovation and design optimization are needed to achieve a more efficient metal filter mesh. Utility Model Content

[0006] Currently, commercially available metal filter meshes are typically fixed using multiple clips or bolts during installation, which is cumbersome. Furthermore, installing the top part requires two workers, reducing manpower utilization. To address these issues, this application provides a high-efficiency metal filter mesh. A cylindrical clamp compresses four limiting posts located inside a cross-shaped plate, allowing these posts to insert into limiting holes within the fixed frame. Simultaneously, under the action of a spring and a sliding plate, the limiting posts reset, separating the filter frame from the fixed frame and enabling quick assembly and disassembly. Furthermore, a single cylindrical clamp controls all four limiting posts to simultaneously fix the filter frame and fixed frame. During operation, the worker simply holds the filter frame with one hand and tightens the threaded post with the other, making it simple and convenient.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0008] A high-efficiency filter metal mesh, comprising:

[0009] Mounting rack;

[0010] A filter frame, wherein a cross plate is fixed inside the filter frame, and a filter metal mesh body is fixed between the cross plate and the filter frame;

[0011] A limiting mechanism, located inside the cross plate, is used to fix the filter frame and the mounting bracket.

[0012] In one possible implementation, the mounting bracket includes a fixed frame located outside the filter frame, a square frame fixed to the outside of the fixed frame, a fixed frame provided on the square frame, a baffle fixed inside the fixed frame, and a fixing hole provided on the square frame to facilitate fixing the mounting bracket by passing bolts through the fixing hole.

[0013] In one possible implementation, a sealing gasket is fixed on the baffle, and the outer side of the filter frame matches the inner side of the fixed frame. The sealing gasket can seal the space between the baffle and the filter frame to prevent gas from passing through the gap between them.

[0014] In one possible implementation, the limiting mechanism includes a limiting hole on the inner side of the fixed frame, a cylindrical cavity at the center of the cross plate, and four moving slots arranged in a circular array inside the cross plate. Each of the four moving slots has a limiting post sliding inside it. The cylindrical cavity is connected to the moving slots, and the limiting post can pass through the moving slots and the through hole and be inserted into the limiting hole to limit the filter frame and the mounting bracket.

[0015] In one possible implementation, the filter frame has a through hole at the position of the moving groove, the through hole is connected to the moving groove, and the limiting post can pass through the through hole and be inserted into the limiting groove, so that the limiting post can be inserted into the limiting hole.

[0016] In one possible implementation, a cylinder is provided inside the cylindrical cavity, and a threaded column is threadedly connected to the cross plate. The threaded column is fixedly connected to the cylinder, and a rotating block is fixed on the threaded column. By rotating the threaded column through the rotating block, the threaded column drives the cylinder to slide inside the cylindrical cavity. The cylinder will squeeze the limiting column, causing the limiting column to move in the moving groove and finally insert into the limiting hole.

[0017] In one possible implementation, the limiting post is provided with an inclined surface at the end near the cylinder, and the inclined surface faces the cylinder, so that the cylinder can squeeze the limiting post.

[0018] In one possible implementation, a sliding cavity is provided inside the moving groove, a spring is provided inside the sliding cavity, a sliding plate slides inside the sliding cavity, the sliding plate is fixedly connected to the limiting post, and the spring is sleeved outside the limiting post. When the limiting post moves due to compression by the cylinder, the limiting post will drive the sliding plate to compress the spring. When the cylinder is no longer compressing the limiting post, the limiting post will move out of the limiting hole and reset under the action of the spring.

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] 1. By pressing the four limiting posts inside the cross plate with the cylinder, the limiting posts can be inserted into the limiting holes inside the fixed frame. At the same time, under the action of the spring and the sliding plate, the limiting posts can be reset. At this time, the filter frame and the fixed frame can be separated, thus completing the quick assembly and disassembly of the fixed frame and the filter frame.

[0021] 2. By setting a single cylinder, four limiting columns can be controlled to simultaneously fix the filter frame and the fixed frame around their perimeter. During operation, the operator only needs to hold the filter frame with one hand and turn the threaded column with the other, which is quite simple and convenient. Attached Figure Description

Detailed Implementation

[0029] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] This embodiment describes the specific structure of a high-efficiency filter metal mesh, as detailed in the following reference. Figures 1-6 As shown, a high-efficiency filter metal mesh includes:

[0031] Mounting rack;

[0032] Filter frame 9, a cross plate 5 is fixed inside the filter frame 9, and a filter metal mesh body 4 is fixed between the cross plate 5 and the filter frame 9.

[0033] The limiting mechanism is located inside the cross plate 5 and is used to fix the filter frame 9 and the mounting bracket.

[0034] Currently, the common metal filter meshes on the market are usually fixed by multiple clips or bolts during installation, which is relatively troublesome in terms of operation. In addition, when it is necessary to install the top part, two workers are required to work together, which reduces the utilization rate of personnel.

[0035] The mounting bracket includes a fixed frame 1 located outside the filter frame 9, a square frame 7 fixed to the outside of the fixed frame 1, a fixed frame 1 on the square frame 7, a baffle 2 fixed inside the fixed frame 1, and a fixing hole 3 on the square frame 7 to facilitate fixing the mounting bracket by passing bolts through the fixing hole 3.

[0036] To prevent air leakage from the gaps, a sealing gasket 10 is fixed on the baffle 2. The outer side of the filter frame 9 matches the inner side of the fixed frame 1. The sealing gasket 10 can seal the gap between the baffle 2 and the filter frame 9 to prevent gas from passing through the gap between them.

[0037] Furthermore, the limiting mechanism includes a limiting hole 8 opened inside the fixed frame 1, a cylindrical cavity 13 opened at the center of the cross plate 5, and four moving slots 14 arranged in a circular array inside the cross plate 5. Each of the four moving slots 14 has a limiting post 11 sliding inside. The cylindrical cavity 13 is connected to the moving slot 14. The limiting post 11 can pass through the moving slot 14 and the through hole 12 and be inserted into the limiting hole 8 to limit the filter frame 9 and the mounting bracket.

[0038] In addition, a through hole 12 is provided on the filter frame 9 at the position of the moving groove 14. The through hole 12 is connected to the moving groove 14. The limiting post 11 can pass through the through hole 12 and be inserted into the limiting groove, so that the limiting post 11 can be inserted into the limiting hole 8.

[0039] More specifically, the cylindrical cavity 13 has a cylinder 16 inside, and a threaded post 17 is threadedly connected to the cross plate 5. The threaded post 17 is fixedly connected to the cylinder 16, and a rotating block 6 is fixed on the threaded post 17. By rotating the threaded post 17 through the rotating block 6, the threaded post 17 drives the cylinder 16 to slide inside the cylindrical cavity 13. The cylinder 16 will squeeze the limiting post 11, so that the limiting post 11 moves in the moving groove 14 and finally inserts into the limiting hole 8.

[0040] It should be noted that the end of the limiting post 11 near the cylinder 16 is set with an inclined surface, and the inclined surface faces the cylinder 16, so that the cylinder 16 can squeeze the limiting post 11.

[0041] At the same time, when the cylinder 16 no longer presses against the limiting post 11, the limiting post 11 needs to move out of the limiting hole 8. The moving groove 14 has a sliding cavity 19 inside, and a spring 18 is provided inside the sliding cavity 19. A sliding plate 15 slides inside the sliding cavity 19. The sliding plate 15 is fixedly connected to the limiting post 11. The spring 18 is sleeved on the outside of the limiting post 11. When the limiting post 11 moves due to the pressure of the cylinder 16, the limiting post 11 will drive the sliding plate 15 to press the spring 18. When the cylinder 16 no longer presses against the limiting post 11, the limiting post 11 will move out of the limiting hole 8 and reset under the action of the spring 18.

[0042] When the staff needs to install the filter frame 9, first fix the mounting bracket to the mounting location with bolts, then align the filter frame 9 with the fixed frame 1 on the mounting bracket and insert it. Then, rotate the threaded post 17 by rotating the block 6, so that the threaded post 17 drives the cylinder 16 to move. The cylinder 16 will squeeze the limiting post 11, and the limiting post 11 will slide in the moving groove 14 and insert into the limiting hole 8 inside the fixed frame 1. At the same time, the limiting post 11 will drive the sliding plate 15 to squeeze the spring 18, thus completing the installation of the filter frame 9. Rotating the threaded post 17 in the opposite direction can remove the filter frame 9 from the fixed frame 1. The operation is simple and takes little time.

[0043] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
