[0027] Example 1

[0028] like Figure 1-5As shown, this is the first embodiment of the present invention. This embodiment provides a support structure for a dust collector filter bag, including a housing 1. Arc-shaped grooves 10 are evenly distributed on the bottom surface of the inner cavity of the housing 1. A fixing ring 6 is disposed above the arc-shaped grooves 10. The structure also includes:

[0029] Buffer mechanism 4 is located near the top of the inner cavity of the arc-shaped groove 10;

[0030] The support positioning mechanism 5 is located at the bottom of the housing 1.

[0031] like Figure 1-5 As shown, the buffer mechanism 4 is located near the top of the inner cavity of the arc-shaped groove 10. It can absorb and disperse the impact force of the airflow on the filter bag, reduce the direct friction between the filter bag body 13 and the support and positioning mechanism 5, thereby reducing wear. At the same time, the support and positioning mechanism 5 ensures the stable positioning of the filter bag body 13, preventing displacement caused by vibration or wind pressure changes, thereby reducing the accumulation of dust on the support and positioning mechanism 5, effectively avoiding blockage, thus effectively improving the service life of the filter bag body 13, and also ensuring the efficient and stable operation of the dust removal system, reducing maintenance frequency and cost. By setting the buffer mechanism 4 and the support and positioning mechanism 5 in the housing 1 and at the bottom, the wear and blockage problems can be effectively solved.

[0032] Example 2

[0033] Reference Figure 1 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] In this embodiment, the buffer mechanism 4 includes a support plate 401, a guide plate 402, a first vent 403, a ventilation arc plate 404, a second vent 405, a damping shock absorber 406, and a buffer washer 407. The guide plate 402 is evenly distributed around the top of the support plate 401. The first vent 403 is evenly opened on the top of the support plate 401. The ventilation arc plate 404 is fixedly connected to the top of the guide plate 402. The second vent 405 is evenly distributed around the top of the ventilation arc plate 404. The damping shock absorber 406 is fixedly installed at the center of the top of the ventilation arc plate 404. The buffer washer 407 is fixedly installed on the top of the damping shock absorber 406. A ventilation duct 2 is fixedly installed on the right side of the housing 1. The ventilation duct 2 is interconnected with the housing 1. A fixing frame 3 is fixedly installed on the right side of the ventilation duct 2. Support members 8 are fixedly installed at the diagonals around the housing 1.

[0035] like Figure 1 and Figure 5As shown, the combination of the support plate 401 and the guide plate 402 ensures uniform airflow distribution and reduces the direct impact of airflow on the filter bag, thereby reducing wear. The setting of the first vent 403 and the second vent 405 optimizes the airflow path, helps prevent dust accumulation on the support structure, and effectively solves the clogging problem. The arc design of the ventilation arc plate 404 further smooths the airflow and reduces the generation of eddies. The addition of the damping shock absorber 406 and the buffer washer 407 provides additional buffering and shock absorption effects, protects the filter bag body 13 from vibration and impact, and extends the service life of the filter bag body 13.

[0036] Example 3

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0038] In this embodiment, the support and positioning mechanism 5 includes a limiting rod 501, a supporting top ring 502, a supporting bottom ring 503, a supporting column 504, a supporting ring sleeve 505, and an arc-shaped groove 506. The top end of the supporting column 504 is fixedly connected to the bottom of the supporting top ring 502, and the end of the supporting column 504 is fixedly connected to the top of the supporting bottom ring 503. The supporting ring sleeve 505 is fixedly fitted onto the outer surface of the supporting column 504. The arc-shaped grooves 506 are evenly distributed on the outer surface of the supporting ring sleeve 505. The limiting rod 501 is engaged in the inner cavity of the arc-shaped groove 506 and is located on the outer surface of the support and positioning mechanism 5. The outer surface of the support and positioning mechanism 5 is fitted with a filter bag body 13. The bottom of the supporting bottom ring 503 is fixedly installed with an air outlet sleeve 9. The inner cavity of the arc-shaped groove 10 is provided with threaded holes 12 around its perimeter, and a ventilation hole 11 is provided at the center of the inner cavity of the arc-shaped groove 10. Fastening bolts 7 are evenly distributed around the top of the fixing ring 6, and the fastening bolts 7 are threadedly connected to the threaded holes 12.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the cooperation between the limiting rod 501 and the arc-shaped groove 506 ensures the accurate position of the filter bag body 13 during installation, preventing the filter bag body 13 from shifting or twisting, thereby ensuring the effective filtration area and filtration efficiency of the filter bag body 13. The top support ring 502 and the bottom support ring 503 are connected by the pillar 504 to form a stable support frame, providing uniform support force for the filter bag body 13, reducing stress concentration caused by wind pressure or vibration, and extending the service life of the filter bag body 13. The setting of the support ring sleeve 505 further enhances the stability of the structure, while facilitating the installation and disassembly of the filter bag body 13, improving the positioning accuracy of the filter bag body 13, enhancing the overall performance and reliability of the dust removal system, and reducing maintenance needs and operating costs caused by improper positioning of the filter bag body 13.

[0040] In summary, the buffer mechanism 4 can absorb and disperse the impact of airflow on the filter bag, reducing the direct friction between the filter bag body 13 and the support and positioning mechanism 5, thereby reducing wear. At the same time, the support and positioning mechanism 5 ensures the stable positioning of the filter bag body 13, preventing displacement caused by vibration or wind pressure changes, thereby reducing dust accumulation on the support and positioning mechanism 5 and effectively avoiding blockage. This effectively improves the service life of the filter bag body 13, ensures the efficient and stable operation of the dust removal system, and reduces maintenance frequency and costs. By setting the buffer mechanism 4 and the support and positioning mechanism 5 inside the housing 1 and at the bottom, the problems of wear and blockage can be effectively solved.
