Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter technology with diaphragms, and more particularly to a high-efficiency filter with diaphragms. Background Technology
[0002] High-efficiency particulate air (HEPA) filters with separators are a common type of air purification equipment, primarily used to filter airborne dust particles in cleanrooms and dust-free workshops. They are widely used at the very end of cleanroom filtration systems in industries such as electronics and optics, medical and pharmaceutical, biological laboratories, food and beverage, daily chemicals and semiconductors, and touchscreen LEDs. They are also used in high-cleanliness environments such as aviation, aerospace, electronics, semiconductors, wafer manufacturing, biopharmaceuticals, hospitals, and the food industry, and can be used as terminal filters in air conditioning and ventilation systems.
[0003] However, most existing filter filters with baffles are fixed with sealant, making the baffles impossible to remove. As a result, when the baffles have been used for a long time, they can only be replaced instead of cleaned, which reduces the usability of the resources and increases unnecessary waste. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a high-efficiency filter with a partition.
[0005] This utility model is achieved by the following technical solution: a high-efficiency filter with a partition, including a fixed frame, a placement groove is provided on the inner wall of the fixed frame, and a filter partition is provided on the inner wall of the fixed frame; both ends of the filter partition are provided with disassembly components.
[0006] The disassembly assembly includes a frame, the inner wall of which has a sliding groove and a limiting groove. A spring is fixedly connected to the left end of the inner wall of the limiting groove. A connecting post is fixedly connected to the end of the spring away from the limiting groove. A limiting block is fixedly connected to the end of the connecting post away from the spring. A limiting post is slidably connected to the inner wall of the sliding groove. A limiting groove is formed on the surface of the limiting post. A spring is fixedly connected to the bottom of the inner wall of the sliding groove. A sliding plate is fixedly connected to the end of the spring away from the sliding groove.
[0007] By pressing the limiting post, the limiting post pushes the sliding plate to compress the spring again. The limiting block, through the connecting post, pushes the spring one to compress again, causing the limiting block to slide out from the inside of the limiting groove two. Then, the limiting post is rotated 90 degrees, thereby pulling out the limiting post, thus releasing the fixation between the frame and the fixed frame, and then pulling the filter plate out from the inside of the fixed frame for cleaning. This reduces resource waste and increases the practicality of the filter.
[0008] As a further improvement to the above scheme, the number of springs is set to two, and the two springs are symmetrically distributed around the limiting post.
[0009] With the above technical solution, by setting spring one, after the limiting post is pulled out from the sliding groove, spring one pushes the connecting post to make the limiting block return to its original position, thus facilitating the insertion and fixing of the limiting post next time.
[0010] As a further improvement to the above solution, the surface of the connecting column is slidably connected to the inner wall of the limiting groove.
[0011] By using the above technical solution, a spring is set so that pressing the limiting post causes the sliding plate to push the spring to compress, and then rotating the limiting post pulls it out, thus facilitating the pulling of the limiting post out of the sliding groove.
[0012] As a further improvement to the above solution, the surface of the limiting block is slidably connected to the inner wall of the limiting groove.
[0013] As a further improvement to the above solution, the surface of the limiting post is slidably connected to the inner wall of the fixing frame.
[0014] As a further improvement to the above solution, the surface of the sliding plate is slidably connected to the inner wall of the sliding groove.
[0015] As a further improvement to the above solution, two placement slots are provided, and the two placement slots are symmetrically distributed with the fixed frame as the center.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This utility model incorporates a disassembly assembly. Specifically, pressing the limiting post causes it to push the sliding plate, compressing the spring again. The limiting block, via the connecting post, further compresses the spring, causing it to slide out of the limiting groove. The limiting post is then rotated 90 degrees to remove it, thus releasing the connection between the frame and the fixed frame. This allows the filter plate to be pulled out from the fixed frame for cleaning, reducing resource waste and increasing the filter's practicality. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] Example:
[0027] Please combine Figure 1-5 This embodiment provides a high-efficiency filter with a partition, a fixed frame 1, an inner wall of the fixed frame 1 with a placement groove 2, and a filter partition 3 on the inner wall of the fixed frame 1; both ends of the filter partition 3 are provided with a disassembly component 4.
[0028] The disassembly assembly 4 includes a frame 401. A sliding groove 402 is formed on the inner wall of the frame 401. A limiting groove 403 is formed on the inner wall of the frame 401. A spring 404 is fixedly connected to the left end of the inner wall of the limiting groove 403. A connecting post 405 is fixedly connected to the end of the spring 404 away from the limiting groove 403. A limiting block 406 is fixedly connected to the end of the connecting post 405 away from the spring 404. A limiting post 407 is slidably connected to the inner wall of the sliding groove 402. A limiting groove 408 is formed on the surface of the limiting post 407. A spring 409 is fixedly connected to the bottom of the inner wall of the sliding groove 402. A sliding plate 410 is fixedly connected to one end of the sliding groove 402. Pressing the limiting post 407 causes the limiting post 407 to push the sliding plate 410 to compress the spring 409 again. The limiting block 406 pushes the spring 404 again through the connecting post 405, thereby causing the limiting block 406 to slide out from the inside of the limiting groove 408. Then, the limiting post 407 is rotated 90 degrees, thereby pulling out the limiting post 407, thereby releasing the fixation between the frame 401 and the fixed frame 1, and then pulling the filter plate 3 out from the inside of the fixed frame 1 for cleaning, thereby reducing resource waste and increasing the practicality of the filter.
[0029] There are two springs 404, and the two springs 404 are symmetrically distributed with the limiting post 407 as the center.
[0030] The surface of the connecting column 405 is slidably connected to the inner wall of the limiting groove 403.
[0031] The surface of the limiting block 406 is slidably connected to the inner wall of the limiting groove 408.
[0032] The surface of the limiting post 407 is slidably connected to the inner wall of the fixed frame 1.
[0033] The surface of the sliding plate 410 is slidably connected to the inner wall of the sliding groove 402.
[0034] There are two placement slots 2, which are symmetrically distributed with the fixed frame 1 as the center.
[0035] The implementation principle of a high-efficiency filter with a partition in this embodiment is as follows: When using the filter with a partition, firstly, a frame 401 is placed over one end of the filter partition 3, and then placed inside the fixed frame 1. Next, four limiting posts 407 are inserted into the sliding groove 402, causing two limiting blocks 406 to push the connecting post 405 to compress the first spring 404. During the slow pushing of the limiting posts 407, the limiting posts 407 push the sliding plate 410, causing the spring 409 to compress accordingly. Then, the first spring 404 extends, pushing the connecting post 405 to push the limiting block 406 into the second limiting groove 408, thereby fixing the limiting post 407 in the sliding groove 402, and thus fixing the fixed frame 1 and the frame 401. Then, another frame 401 is placed over the filter partition. At the other end of the baffle 3, the same operation as above is performed, so that the filter baffle 3 can be firmly fixed inside the fixed frame 1. When the filter baffle 3 needs to be cleaned after a long period of use, first press the four limiting posts 407 on one of the frame 401, so that the limiting posts 407 push the sliding plate 410 to compress the spring 409 again. The limiting block 406 pushes the spring 404 again through the connecting post 405, and then the limiting block 406 slides out from the inside of the limiting groove 408. Then rotate the limiting post 407 90 degrees, so as to pull out the limiting post 407, thereby releasing the fixation between the frame 401 and the fixed frame 1, and then pull the filter baffle 3 out from the inside of the fixed frame 1 for cleaning, thereby reducing resource waste and increasing the practicality of the filter.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
