Description

Technical Field

[0001] This utility model belongs to the field of bag filtration technology, and more specifically, it relates to a high-efficiency pleated bag filtration device. Background Technology

[0002] With the rapid advancement of industrialization, environmental standards are becoming increasingly stringent. The large amounts of dust pollutants generated by various industrial production activities face stricter emission limits. To ensure that the dust in emissions meets these standards, a high-efficiency pleated bag filter is needed. Existing high-efficiency pleated bag filters have optimized the bag structure, using pleats to increase the filtration area and effectively improve filtration efficiency and precision. During gas filtration, dust-laden gas enters the housing through the inlet. Due to the sudden expansion of the airflow cross-section, some larger dust particles settle within the housing under the influence of gravity and inertia. Fineer, less dense dust particles enter the filtration chamber with the airflow, where, through Brownian diffusion and sieving, the dust is trapped on the surface of the pleated bags. Clean gas then passes through the inside of the filter bags into the clean air chamber and is finally discharged through the exhaust pipe by a fan.

[0003] This utility model, with application number CN202222107395.8, relates to the field of filter bag technology and discloses a pleated filter bag with good sealing performance. It includes a filter bag body, with a fixing mechanism installed on one side of the outer wall of the filter bag body. The fixing mechanism includes a clamp, a sealing plate, a hinge, a fixing plate, and a fixing bolt. The clamp is engaged and installed on the outer wall of the filter bag body. This well-sealed pleated filter bag, by incorporating the clamp, sealing plate, hinge, fixing plate, and fixing bolt, allows the filter bag body to be connected to other equipment via a connecting pipe. By adjusting the size of the clamp, the hinge rotates, clamping and fixing the filter bag body onto the connecting pipe. Rotating the fixing bolt tightens the fixing plate, thus securing the filter bag body with the clamp. This results in a better sealing effect during use, preventing leakage and improving the overall performance of the filter bag, meeting user needs.

[0004] Based on the above, existing high-efficiency pleated bag filter devices involve attaching the pleated bag to the outside of the support frame and then securing it using clamps, binding ropes, bolts, etc., before installing it into the filter housing for filtration. While these fixing methods ensure a tight installation and guarantee filtration efficiency, the installation process is quite cumbersome. Moreover, when disassembling and maintaining the pleated bag is required, each fixing component must be removed individually, consuming considerable time and manpower, increasing maintenance costs and difficulty.

[0031] The specific usage and function of this embodiment are as follows:

[0032] The pleated bag body 1 is fitted onto the outside of the support frame 2. The limiting ring 301 limits the position of the support ring 101. The outside of the guide ring 401 pushes one end of the multiple sets of limiting blocks 5 out from the inside of the multiple sets of guide grooves 302, so that the support ring 101 is engaged in the middle position between the multiple sets of limiting blocks 5 and the limiting ring 301. The sealing gasket set at the bottom of the limiting ring 301 plays a sealing role between the limiting ring 301 and the support ring 101.

[0033] Example 2: Based on Example 1, as follows Figures 1 to 7 As shown, it also includes: a socket assembly, which is disposed inside the mounting ring 3.

[0034] The socket assembly includes a spring groove 304 and a second elastic member 6. The spring groove 304 is formed on the top of the mounting ring 3. The end of the second elastic member 6 is fixedly installed inside the spring groove 304, and the top of the second elastic member 6 is fixedly installed on the bottom of the pressing plate 4.

[0035] The socket assembly further includes: a limiting slide groove 303, a transmission plate 501, and a first elastic element 502. Multiple sets of limiting slide grooves 303 are arranged in a circumferential array inside the mounting ring 3, and the multiple sets of limiting slide grooves 303 and multiple sets of guide slide grooves 302 are interconnected. Multiple sets of transmission plates 501 are arranged, slidably connected inside the multiple sets of limiting slide grooves 303, and fixedly connected to the top of the multiple sets of limiting blocks 5. Multiple sets of first elastic elements 502 are arranged, with one end fixedly connected inside the multiple sets of limiting slide grooves 303, and the other end fixedly connected to the inner side of the multiple sets of transmission plates 501.

[0037] The specific usage and function of this embodiment are as follows:

[0038] When the main body 1 of the pleated bag needs to be disassembled for replacement or maintenance, press the pressing plate 4. The pressing plate 4 drives the guide ring 401 to slide inside the mounting ring 3 and compresses the second elastic element 6 into the spring groove 304. The movement of the guide ring 401 drives the annular groove 402 to the position of the limiting block 5, which is aligned with the guide slide 302. The first elastic element 502 resets under the elastic action. The first elastic element 502 drives the transmission plate 501 to slide inside the limiting slide 303. The limiting slide 303 plays a guiding and limiting role when the transmission plate 501 moves, and further limits the position of the limiting block 5. The movement of the transmission plate 501 drives the limiting block 5 to move. The movement of the limiting block 5 causes the end to enter the annular groove 402 and the beginning to be hidden inside the guide slide 302. This allows the limiting block 5 to release the limitation on the supporting ring 101, making it convenient to disassemble or replace the main body 1 of the pleated bag.

[0039] When the pressing plate 4 is released, the second elastic element 6 resets under the elastic action. The second elastic element 6 drives the pressing plate 4 and the guide ring 401 to reset. The movement of the guide ring 401 drives the annular groove 402 and the inclined groove 403 to move. The inclined structure of the inclined groove 403 pushes the limiting block 5 out of the annular groove 402, so that one end of the limiting block 5 is pushed out of the guide slide 302, and the supporting ring 101 is locked and limited.
