Description

Technical Field

[0001] This utility model relates to the field of cleanroom purification technology, specifically to a painted mesh structure on the outside of a filter screen. Background Technology

[0002] To ensure a clean environment, cleanrooms typically install filters to filter the air. Inside these filters, to facilitate the filtration of impurities in the air, a filter screen is usually used. This filter screen is made of painted mesh. Currently available painted mesh screens generally come with a corresponding installation mechanism, which is used to install them inside the filter and fix their position. However, during use, a large amount of dust accumulates on the outside of the painted mesh and cannot be removed. Traditional methods using scrapers to move the painted mesh only reposition the dust and impurities; the displaced dust and impurities still accumulate on the mesh. Therefore, over time, the accumulation of impurities on the surface of the painted mesh affects its normal filtration efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a painted mesh structure for the outside of a filter screen, in order to solve the problem mentioned in the background art that when painted meshes on the market are used, a large amount of dust accumulates on their surface and cannot be removed. Traditionally, a scraper is set on the painted mesh to scrape it, which can only move the dust and impurities to a different location. However, the moved dust and impurities will still accumulate on the painted mesh and cannot be removed. Therefore, when painted meshes are used for a long time, a large amount of impurities accumulate on their surface, which will affect their normal filtration efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a paint-coated mesh structure for the outside of a filter screen, comprising a fixing body, which is a rectangular frame structure used for installing the paint-coated mesh;

[0005] The painted mesh mechanism is located in the middle of the fixed body and is installed inside the filter through the fixed body for filtration.

[0006] Also includes;

[0007] The shaking mechanism includes a rotating trigger block, a trigger plate, a mounting column, and a compression spring. The rotating trigger block rotates and contacts the trigger plate, causing the trigger plate to drive the paint mesh mechanism mounted at its bottom to shake up and down along the outside of the mounting column under the action of the compression spring, thus completing the shaking of impurities and dust.

[0008] Preferably, the fixing body includes an upper frame, a lower frame, a connecting rod, and an intermediate cylinder. The upper frame and the lower frame are both rectangular frame structures and are arranged one above the other.

[0009] Two connecting rods are symmetrically arranged at the bottom of the lower frame, and an intermediate cylinder is integrally installed between the two connecting rods.

[0010] Preferably, the bottom of the upper frame and the top of the lower frame are each provided with four rectangularly distributed threaded grooves, and the threaded grooves on the upper frame and the lower frame correspond to each other. A mounting post is threaded between the two corresponding threaded grooves on the upper and lower frames.

[0011] The top bearing of the intermediate cylinder is connected to the mounting cylinder. A rotating trigger block is integrally mounted on the outside of the mounting cylinder. A polygonal groove is embedded inside the mounting cylinder for connecting with an external drive device. The bottom of the rotating trigger block is evenly distributed with bristles, and its bottom engages with the mesh on the uncompressed and lowered paint-coated mesh mechanism.

[0012] Preferably, the paint-coated mesh mechanism includes a paint-coated mesh plate and a central perforation. The paint-coated mesh plate is arranged in an arc shape, and its cross-sectional dimension is larger than that of the internal hollow structure of the fixing body. A central perforation is provided in the middle of the paint-coated mesh plate for the installation of the cylinder through the hole.

[0013] The top of the paint-coated screen is provided with a mesh that engages with the bristles at the bottom of the rotating trigger block.

[0014] Preferably, the outer side of the painted mesh plate is further provided with four mounting posts arranged in a rectangular shape. The position of the connecting cylinder corresponds to the position of the mounting posts, and a trigger plate is integrally installed at the upper part of the connecting cylinder. The connecting cylinder is sleeved on the outside of the mounting posts.

[0015] Preferably, a compression spring is also fitted around the lower outer surface of the mounting column, and a connecting cylinder is provided at the top of the compression spring.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The painted mesh structure on the outside of the filter screen is equipped with a shaking mechanism. Connecting the top of the entire mounting cylinder to the external driving mechanism causes the rotating trigger block to rotate. When rotating, it squeezes the trigger plate, causing the trigger plate to drive the connecting cylinder at its top to shake up and down under the action of the compression spring. Since the bottom of the connecting cylinder is connected to the painted mesh plate, the painted mesh plate will also shake continuously. During the shaking, the brush bristles at the bottom of the trigger plate continuously clean and disperse dust and impurities, allowing the dispersed dust and impurities to fall to the outside through the painted mesh plate, preventing them from accumulating on the painted mesh plate for a long time. The continuous shaking of the painted mesh plate also separates impurities from the mesh, thus ensuring that the painted mesh plate can perform continuous and efficient filtration.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model provides a technical solution: a paint-coated mesh structure for the outside of a filter screen, including a fixing body 1, which is a rectangular frame structure used for installing the paint-coated mesh;

[0025] The paint-coated mesh mechanism 2 is located in the middle of the fixed body 1 and is installed inside the filter through the fixed body 1 for filtration.

[0026] Also includes;

[0027] The shaking mechanism includes a rotating trigger block 3, a trigger plate 4, a mounting column 5, and a compression spring 6. The rotating trigger block 3 rotates and contacts the trigger plate 4, causing the trigger plate 4 to drive the paint mesh mechanism 2 installed at its bottom to shake up and down along the outside of the mounting column 5 under the action of the compression spring 6, thus completing the shaking work of impurities and dust.

[0028] This application provides a painted mesh structure with a shaking mechanism on the outside of the filter screen. Specifically, in use, the painted mesh mechanism 2 is first installed inside the fixed body 1. Then, by installing the fixed body 1 inside the filter, dust and impurities can be filtered through the painted mesh mechanism 2. During filtration, when impurities accumulate on the painted mesh mechanism 2, the rotating trigger block 3 can be controlled to rotate. When rotating, it will continuously contact the trigger plate 4, thereby squeezing the trigger plate 4. Since the painted mesh mechanism 2 is provided at the bottom of the trigger plate 4, the trigger plate 4 and the painted mesh mechanism 2 at its bottom will continuously shake at the top of the compression spring 6, thereby preventing impurities from clogging the mesh holes on the painted mesh mechanism 2 and achieving a continuous and efficient filtration effect.

[0029] Among them, according to Figure 1-4 As shown, the fixing body 1 includes an upper frame 11, a lower frame 12, a connecting rod 13 and an intermediate cylinder 14. The upper frame 11 and the lower frame 12 are both rectangular frame structures and are arranged one above the other.

[0030] Two connecting rods 13 are symmetrically arranged at the bottom of the lower frame 12, and an intermediate cylinder 14 is integrally installed between the two connecting rods 13.

[0031] The bottom of the upper frame 11 and the top of the lower frame 12 are provided with four rectangularly distributed threaded grooves, and the threaded grooves on the upper frame 11 and the lower frame 12 correspond to each other. A mounting post 5 is threadedly connected between the two corresponding threaded grooves on the upper and lower frames.

[0032] The top bearing of the intermediate cylinder 14 is connected to the mounting cylinder 31. The rotating trigger block 3 is integrally mounted on the outside of the mounting cylinder 31. The interior of the mounting cylinder 31 is inlaid with polygonal grooves for connecting with external drive equipment. The bottom of the rotating trigger block 3 is evenly distributed with bristles, and its bottom engages with the mesh on the uncompressed and lowered paint-coated mesh mechanism 2.

[0033] The paint-coated mesh mechanism 2 includes a paint-coated mesh plate 21 and a central perforation 22. The paint-coated mesh plate 21 is arranged in an arc shape, and its cross-sectional dimension is larger than the internal hollow structure of the fixed body 1. A central perforation 22 is passed through the middle of the paint-coated mesh plate 21 for the installation of the cylinder 31 through the hole.

[0034] The top of the painted mesh plate 21 is provided with mesh holes that engage with the brush bristles at the bottom of the rotating trigger block 3;

[0035] The outer side of the painted mesh plate 21 also has four mounting posts 5 arranged in a rectangle. The position of the connecting cylinder 7 corresponds to the position of the mounting posts 5. A trigger plate 4 is also integrally installed on the upper part of the connecting cylinder 7. The connecting cylinder 7 is sleeved on the outside of the mounting posts 5.

[0036] A compression spring 6 is also fitted on the lower outer side of the mounting column 5, and a connecting cylinder 7 is provided at the top of the compression spring 6.

[0037] Specifically, when installing the paint-coating mesh mechanism 2 and the fixed body 1, the mounting post 5 between the upper frame 11 and the lower frame 12 needs to be rotated first to separate it from the upper frame 11 and the lower frame 12. Then, the compression spring 6 and the connecting cylinder 7 are respectively sleeved on the bottom of the mounting post 5. After that, the side of the mounting post 5 with the compression spring 6 is threaded to the lower frame 12, and the other side is threaded to the upper frame 11. This completes the installation of the fixed body 1 and the paint-coating mesh mechanism 2. After that, the fixed body 1 is installed with the external filter and can be used.

[0038] In use, firstly, the internal groove of the mounting cylinder 31 is connected to the drive motor and other components, causing the mounting cylinder 31 to rotate. This rotation drives the rotating trigger block 3 at its top to rotate, causing it to contact the trigger plate 4 on the outside of the connecting cylinder 7. This causes the trigger plate 4 to be pressed, which in turn compresses the compression spring 6 of the connecting cylinder 7 at its top. When the rotating trigger block 3 separates from the trigger plate 4, the compression spring 6 returns to its original position, causing the connecting cylinder 7, trigger plate 4, and painted mesh plate 21 to vibrate and reset, thus achieving a vibration effect. As the rotating trigger block 3 rotates continuously, the bristles at its bottom continuously scrape and disperse impurities on the painted mesh plate 21, ensuring that small impurities fall and are discharged, while large impurities are continuously shaken and separated from the mesh, ensuring that the mesh on the painted mesh plate 21 remains open, thereby achieving a high-efficiency filtration effect. Content not described in detail in this specification is prior art known to those skilled in the art.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
