Description
Technical Field
[0001] This utility model belongs to the technical field of filter bags, specifically a self-cleaning, anti-static, high-temperature resistant filter bag. Background Technology
[0002] Filter bags are a key component in the operation of baghouse dust collectors. Cylindrical filter bags are typically suspended vertically inside the dust collector. Filter bags can work continuously in high-temperature environments. The fabric and design of filter bags should strive for high-efficiency filtration, easy dust removal, and durability.
[0003] In pulse and air-box type pulse dust collectors, high-temperature resistant filter bags are installed at the path where gas and dust flow out. After the dust and gas pass through the filter bag, the dust is filtered and captured on the outer surface of the filter bag, while the clean gas enters the inside of the filter bag through the filter material and flows out from the inside of the filter bag. The cage inside the filter bag is used to support the filter bag and prevent the filter bag from collapsing.
[0004] After working inside a dust collector for a long time, a filter cake layer composed of dust particles gradually accumulates on the outer surface of the filter bag. The pores of the filter cake layer are finer than the filter bag fibers, which can further trap micron-sized or even submicron-sized dust particles. However, as the filter cake layer accumulates thicker, it leads to excessive dust filtration resistance, requiring regular cleaning of the filter cake layer. Current technology generally involves blowing airflow into the filter bag to deform it and shake off the filter cake layer accumulated on the outer surface. However, because the filter bag is equipped with a support cage inside, the deformation of the filter bag is limited, and it is impossible to completely shake off the filter cake layer accumulated on the outer surface. The filter bag still needs to be removed by the staff for manual cleaning, which is inefficient in cleaning the filter cake layer on the outer surface of the filter bag. Therefore, to address the above problems, a self-cleaning, anti-static, high-temperature resistant filter bag is proposed. Utility Model Content

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-7As shown, a self-cleaning, anti-static, high-temperature resistant filter bag includes a support cage 1, a connecting sleeve 2 fixedly installed on the top of the support cage 1, a slide 21 opened on the inner wall of the connecting sleeve 2, a circular rotating ring 3 slidably installed inside the slide 21, a fixing sleeve 31 fixedly installed on the outer surface of the circular rotating ring 3, a filter bag body 4 snapped into the inside of the fixing sleeve 31, a cleaning component 41 installed at the bottom of the connecting sleeve 2, and a rotating component 5 installed at the top of the fixing sleeve 31.
[0030] Furthermore, by attaching the head end of the filter bag body 4 to the inside of the fixing sleeve 31, and then installing the fixing sleeve 31 into the inside of the connecting sleeve 2, the fixing sleeve 31 can rotate within the slide 21 opened on the inner wall of the connecting sleeve 2 by means of the circular rotating ring 3 fixedly installed on its outer surface. Thus, the fixing sleeve 31 can drive the filter bag body 4 to rotate, and the support cage 1 is placed inside the filter bag body 4 to support the shape of the filter bag body 4. Then, the cleaning component 41 is installed on the outside of the filter bag body 4, so that by rotating the rotating component 5 on the top of the fixing sleeve 31, the outer surface of the filter bag body 4 can be cleaned by the cleaning component 41.
[0031] It should be noted that the slide 21 is opened on the inner wall of the connecting sleeve 2, and the bottom of the inner wall of the slide 21 penetrates the bottom of the connecting sleeve 2, so that the fixing sleeve 31 can be inserted into the interior of the connecting sleeve 2 for installation and removal. The filter bag body 4 is made of conductive fiber and filter fiber material blended or interwoven in a certain proportion, which can effectively achieve anti-static treatment.
[0032] First, considering the issue of how to clean the filter plate layer that is connected to the outer surface of the filter bag body 4, the following is presented: Figures 2-7 The specific structure of the cleaning component 41 is disclosed. The cleaning component 41 includes a fixing ring 401 fixedly installed at the bottom of the connecting sleeve 2. An arc-shaped plate 402 is fixedly installed at the bottom of the fixing ring 401. A fixing ring 403 is fixedly installed at the bottom of the arc-shaped plate 402. A connecting rod 404 is fixedly installed on the side of the arc-shaped plate 402 near the support cage 1. A cleaning brush head 405 is installed on the side of the connecting rod 404 away from the arc-shaped plate 402.
[0033] A backing plate 11 is fixedly installed on the outer surface of the support cage 1, and the backing plate 11 is located inside the filter bag body 4. There are two connecting rods 404 and cleaning brush heads 405, which are arranged in a circumferential array on the outer surface of the filter bag body 4.
[0034] Furthermore, a fixing sleeve 31 is installed inside the connecting sleeve 2, thus dividing the bottom of the connecting sleeve 2 into two circular bottom surfaces. The circular bottom surface located inside the filter bag body 4 is fixedly installed on the top of the support cage 1, and a fixing ring 401 is fixedly installed on the bottom of the circular bottom surface located outside the filter bag body 4. This allows the arc-shaped plate 402 to be fixedly installed on the bottom of the fixing ring 401 and to be fixedly connected to the fixing ring 403, so that the arc-shaped plate 402 is installed on the outer surface of the filter bag body 4. A cleaning brush head 405 is installed on the side of the arc-shaped plate 402 near the filter bag body 4. Thus, when the fixing sleeve 31 rotates inside the connecting sleeve 2, it can carry... The filter bag body 4 passes through the cleaning brush head 405, which can clean the filter cake layer on the outer surface of the filter bag body 4. When the cleaning brush head 405 comes into contact with the filter bag body 4, the filter bag body 4 is a deformable structure, which may cause the cleaning brush head 405 to push the filter bag body 4 and fail to clean it. A backing plate 11 is installed on the outer surface of the support cage 1, so that the backing plate 11 can be in the same position as the cleaning brush head 405 inside the filter bag body 4. The backing plate 11 can prevent the filter bag body 4 from deforming. The backing plate 11 and the filter bag body 4 work together to thoroughly clean the outer surface of the filter bag body 4, achieving the effect of self-cleaning the outer surface of the filter bag body 4.
[0035] It should be noted that the cleaning brush head 405 needs to be placed on the outside of the filter bag body 4 and operate in a high-temperature environment. The brush head of the cleaning brush head 405 is made of ceramic sponge material, which is not affected by the high-temperature environment and can avoid scratching the filter bag body 4 when cleaning it.
[0036] Secondly, considering the issue of how to rotate the fixing sleeve 31 inside the connecting sleeve 2, a diagram is provided. Figure 1 and Figure 5 The specific structure of the rotating component 5 is disclosed. The rotating component 5 includes an arc-shaped slide groove 501 opened on the top of the connecting sleeve 2. A sliding column 502 is slidably installed inside the arc-shaped slide groove 501. The bottom of the sliding column 502 passes through the arc-shaped slide groove 501 and is fixedly installed on the top of the fixed sleeve 31. A limit block 503 is installed on the top of the sliding column 502. A fastening cap 504 is threadedly connected to the outer surface of the sliding column 502.
[0037] The inner wall of the circular swivel ring 3 has a through-hole, and the inside of the through-hole is connected to a fixing bolt 6.
[0038] Furthermore, an arc-shaped groove 501 is formed at the top of the connecting sleeve 2, with its bottom extending into the interior of the connecting sleeve 2. The sliding post 502 is rotatably installed into the arc-shaped groove 501, allowing its bottom to be fixedly installed onto the top of the fixing sleeve 31 inside the connecting sleeve 2. A fastening cap 504 is then threaded onto the outer surface of the sliding post 502. Rotating the fastening cap 504 against the top of the connecting sleeve 2 limits and fixes the sliding post 502 within the arc-shaped groove 501, and similarly limits and fixes the fixing sleeve 31 to the connecting sleeve 2. Inside, the limiting block 503 is installed on the top of the sliding column 502 to prevent the fastening cap 504 from dislodging from the sliding column 502 and causing the fixing sleeve 31 to fall off from the connecting sleeve 2. When cleaning the filter bag body 4, the fastening cap 504 is rotated to loosen it, which can pull the limiting block 503 to drive the sliding column 502 to rotate inside the arc-shaped sliding groove 501. Then the fixing sleeve 31 and the filter bag body 4 can rotate together and pass through the cleaning component 41 for cleaning, achieving the effect of rotating the filter bag body 4 and limiting the installation of the fixing sleeve 31 and the filter bag body 4 inside the connecting sleeve 2.
[0039] It should be noted that the filter bag body 4 may fall off when it is snapped into the inside of the fixing sleeve 31. A through hole is opened in the inner wall of the circular rotating ring 3 so that the fixing bolt 6 can be threaded into the inside of the through hole. Then, one end of the fixing bolt 6 can pass through the through hole and press against the head end of the filter bag body 4, thus limiting and fixing the filter bag body 4 into the inside of the fixing sleeve 31.
[0040] Finally, considering the issue of dust leakage from the interface between the connecting sleeve 2 and the filter port when the connecting sleeve 2 and the filter bag body 4 are placed inside the filter port, a [details omitted] is provided. Figure 7 A retaining ring 7 is fixedly installed on the outer surface of the connecting sleeve 2, and a sealing gasket 71 is installed at the bottom of the retaining ring 7 for sealing the filter bag body 4.
[0041] Furthermore, a retaining ring 7 is fixedly installed on the outer surface of the connecting sleeve 2, and a sealing gasket 71 is installed at the bottom of the retaining ring 7. When the connecting sleeve 2 is inserted into the filter port of the dust collector, the retaining ring 7 can be locked onto the outside of the filter port, and the sealing gasket 71 can make the filter port and the connecting sleeve 2 more tightly connected, which can prevent dust leakage.
[0042] In summary, the working principle of this utility model is as follows:
[0043] When using the filter bag body 4, place the head end of the filter bag body 4 into the inside of the fixing sleeve 31, and rotate the fixing bolt 6 inside the through-hole so that the fixing bolt 6 holds the filter bag body 4 against the inside of the fixing sleeve 31 for fixed installation. Then, insert the fixing sleeve 31 into the inside of the connecting sleeve 2, with the circular rotating ring 3 aligned with the inside of the slide rail 21. The sliding post 502 at the top of the fixing sleeve 31 passes through the bottom of the arc-shaped slide groove 501 to the top of the connecting sleeve 2. Thread the fastening cap 504 from the top of the connecting sleeve 2 to the outer surface of the sliding post 502, and install the limiting block 503 on the top of the sliding post 502. Rotate the fastening cap 504 against the top of the connecting sleeve 2 to fix and limit the fixing sleeve 31 and the filter bag body 4 inside the connecting sleeve 2. When connected to the connecting sleeve 2, the filter bag body 4 has already fitted the support cage 1 inside, so that the support cage 1 and the abutment plate 11 are supported inside the filter bag body 4. The arc plate 402 is also installed on the outer surface of the filter bag body 4. After the filter bag body 4 is placed inside the dust collector, it is sealed by the retaining ring 7 and the sealing gasket 71, so that the filter bag body 4 can work and filter dust. When dust accumulates on the outer surface of the filter bag body 4 and needs to be cleaned, the fastening cap 504 is loosened, and the sliding column 502 is pulled to rotate inside the arc groove 501, which drives the filter bag body 4 to rotate together. Then the outer surface of the filter bag body 4 will be swept by the cleaning brush head 405 to remove the dust accumulated on the outer surface of the filter bag body 4, achieving the effect of self-cleaning of the filter bag body 4.
