Description

Technical Field

[0001] This utility model relates to the field of long filter bag technology, and in particular to an anti-movement mechanism for long filter bags. Background Technology

[0002] Filter bags possess excellent chemical stability and heat resistance, representing the highest performance in the filter media industry and the most advanced type of commonly used filter materials. They achieve high levels in filtration efficiency and precision. There are many types of filter bags, one of which is the long filter bag.

[0003] Long filter bags require special attention to prevent movement in industrial dust removal systems, primarily due to the following technical reasons and practical impacts: friction between the filter bag and the cage leads to wear on the base fabric (e.g., the coefficient of friction of PPS fiber reaches 0.35-0.45 at 260℃), and long-term movement can shorten the filter bag's lifespan by 30%-50%. Therefore, there is an urgent need for an anti-movement mechanism for long filter bags to change this situation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-movement mechanism for long filter bags. Its advantages include providing excellent fixation, preventing the long filter bags from shifting during operation, reducing wear and tear, and extending their service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An anti-movement mechanism for long filter bags includes a frame, a filter bag being sleeved on the outside of the frame, and the filter bag being mounted on the frame by a limiting component.

[0007] The limiting assembly includes an upper limiting half ring and a lower limiting half ring, which are connected by limiting bolts. The top of the lower limiting half ring has a contraction groove, and the inner wall of the contraction groove is connected to a sliding plate by a compression spring. The sliding plate can slide in the contraction groove. The top of the sliding plate is provided with a connecting post, which is connected to the upper limiting half ring.

[0008] The above technical solution involves placing the filter bag over the frame during use, fitting the limiting component over the frame opening, and then tightening the limiting bolts. The limiting bolts cause the upper and lower limiting half-rings to move closer together, firmly pressing and fixing the filter bag to the frame surface. This provides a good fixing effect, preventing the long filter bag from shifting during operation, reducing wear and tear on the long filter bag, and extending its service life.

[0009] The present invention is further provided that the opening of the skeleton is provided with a plurality of anti-slip ribs, and the anti-slip ribs are integrally formed with the skeleton.

[0010] The above technical solutions, including the anti-slip ribs, increase the friction between the frame and the filter bag, thereby improving the stability of the filter bag installation.

[0011] The present invention is further configured such that the cross-section of the anti-slip rib is semi-circular.

[0012] The above technical solution, with its semi-circular cross-section, ensures a smooth surface for the anti-slip ribs, preventing the filter bag from being worn through.

[0013] The present invention is further configured such that the inner walls of the upper limit semi-ring and the lower limit semi-ring are provided with pressure strips, and the pressure strips can enter into the gaps of the anti-slip ribs.

[0014] The above technical solution, with its pressure strip, allows the filter bag to be easily squeezed into the gap between the two anti-slip ribs, further improving the stability of the filter bag installation.

[0015] The present invention is further provided that the inner wall of the pressure strip is provided with anti-slip protrusions, and the anti-slip protrusions are integrally formed with the pressure strip.

[0016] The above technical solutions, including the anti-slip protrusions, increase the friction between the pressure strip and the filter bag, further improving the stability of the filter bag installation.

[0017] The present invention is further configured such that the pressure strip is made of rubber.

[0018] Through the above technical solutions: the pressure strip made of rubber has good elasticity, which makes it easy to firmly fix the filter bag in the gap between the two anti-slip ribs, and prevent the filter bag from moving around during operation.

[0019] The present invention is further configured such that an inner groove is provided at the middle position of the outer wall of the upper limit half ring and the lower limit half ring on opposite sides, and an extrusion block is connected to the inner groove by a compression spring, and the extrusion block can slide in the inner groove.

[0020] Through the above technical solution: when the limiting component fixes the filter bag and the frame, the squeezing block, under the action of the compression spring, firmly presses the filter bag onto the surface of the frame, improving the stability of the filter bag installation.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This anti-movement mechanism for long filter bags works by placing the filter bag over the frame, fitting the limiting component over the frame opening, and then tightening the limiting bolts. The limiting bolts cause the upper and lower limiting half-rings to move closer together, firmly pressing and fixing the filter bag to the frame surface. This provides a good fixing effect, preventing the long filter bag from moving during operation, reducing wear and tear, and extending the service life of the long filter bag.

[0023] 2. The anti-slip mechanism for long filter bags features anti-slip ribs that increase friction between the frame and the filter bag, improving the stability of the filter bag installation. The semi-circular cross-section design ensures a smooth surface for the anti-slip ribs, preventing the filter bag from being worn through.

[0024] 3. The anti-slip mechanism for long filter bags features a pressure strip that easily compresses the filter bag into the gap between two anti-slip ribs, further improving the stability of the filter bag installation; the anti-slip ribs increase the friction between the pressure strip and the filter bag, further enhancing the firmness of the filter bag installation.

[0030] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0031] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0032] Example 1

[0033] Reference Figure 1-4 An anti-movement mechanism for long filter bags includes a frame 1, with a filter bag 2 sleeved on the outside of the frame 1, characterized in that the filter bag 2 is mounted on the frame 1 by a limiting component.

[0034] The limiting assembly includes an upper limiting half ring 3 and a lower limiting half ring 4, which are connected by limiting bolts 5. A shrinkage groove 6 is provided at the top of the lower limiting half ring 4. A sliding plate 8 is connected to the inner wall of the shrinkage groove 6 by a compression spring 7. The sliding plate 8 can slide in the shrinkage groove 6. A connecting post 9 is provided at the top of the sliding plate 8, and the connecting post 9 is connected to the upper limiting half ring 3.

[0035] In this embodiment, a plurality of anti-slip ribs 10 are provided at the opening of the frame 1. The anti-slip ribs 10 are integrally formed with the frame 1. The anti-slip ribs 10 can increase the friction between the frame 1 and the filter bag 2, thereby improving the stability of the filter bag 2 installation. The cross-section of the anti-slip ribs 10 is semi-circular. The semi-circular cross-section of the anti-slip ribs 10 can make the surface of the anti-slip ribs 10 smooth, thus preventing the filter bag 2 from being worn through.

[0036] Furthermore, the inner walls of both the upper limit semi-ring 3 and the lower limit semi-ring 4 are provided with pressure strips 11. The pressure strips 11 can enter the gaps between the anti-slip ribs 10. The pressure strips 11 can easily squeeze the filter bag 2 into the gap between the two anti-slip ribs 10, further improving the stability of the filter bag 2 installation. The inner wall of the pressure strip 11 is provided with anti-slip protrusions 12, which are integrally formed with the pressure strip 11. The anti-slip protrusions 12 can increase the friction between the pressure strip 11 and the filter bag 2, further improving the firmness of the filter bag 2 installation. The pressure strip 11 is made of rubber. The rubber pressure strip 11 has good elasticity, which makes it easy to firmly fix the filter bag 2 in the gap between the two anti-slip ribs 10, preventing the filter bag 2 from moving around during operation.

[0037] Working principle: When in use, the filter bag 2 is placed on the outside of the frame 1, and the limiting component is placed on the opening of the frame 1. Then, by tightening the limiting bolt 5, the limiting bolt 5 causes the upper limiting half ring 3 and the lower limiting half ring 4 to move closer to each other. The upper limiting half ring 3 and the lower limiting half ring 4 firmly press and fix the filter bag 2 to the surface of the frame 1, which achieves a good fixing effect, prevents the long filter bag from moving around during operation, reduces the wear of the long filter bag during operation, and improves the service life of the long filter bag.

[0038] Example 2

[0039] This second embodiment is based on the first embodiment, and is more specific, such as... Figure 3 As shown, an inner groove 13 is provided at the middle position of the outer wall of the upper limit half ring 3 and the lower limit half ring 4 on opposite sides. The inner groove 13 is connected to a squeezing block 15 through a compression spring 14. The squeezing block 15 can slide in the inner groove 13. When the limiting component fixes the filter bag 2 and the frame 1, the squeezing block 15 presses the filter bag 2 firmly onto the surface of the frame 1 under the action of the compression spring 14, which improves the stability of the filter bag 2 installation.
