Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, specifically a tension regulator for filter bags in negative pressure baghouse dust collectors. Background Technology

[0002] Negative pressure baghouse dust collectors, as highly efficient air purification equipment, are widely used in industrial production fields such as steel, cement, chemical, and power industries. Their main function is to filter dust-laden gas through filter bags, trapping dust on the surface of the filter bags and allowing the purified gas to be discharged. This achieves the goals of reducing air pollution, protecting the environment, and meeting the clean air requirements of production processes. However, in actual operation, the tension state of the filter bags has a crucial impact on the performance of the dust collector and the service life of the filter bags.

[0003] Some existing filter bag tension adjustment devices use simple mechanical structures, such as adjusting the tension of the filter bags by tightening bolts. This method is not only cumbersome, requiring manual adjustment of each filter bag individually, but also difficult to guarantee in terms of adjustment accuracy. Due to the lack of precise measurement and feedback mechanisms, operators often have to rely on experience to make adjustments, making it difficult to adjust the tension of all filter bags to a consistent and suitable level. This results in uneven tension across the entire filter bag assembly, affecting the stable operation of the dust collector. Utility Model Content

[0016] Please see Figure 1-4 As shown, the filter bag tension regulator for a negative pressure bag filter dust collector includes a connecting ring 1, and also includes: a turntable 2 slidably installed inside the connecting ring 1, a limit groove 3 on the turntable 2, a connecting seat 4 fixedly installed on the connecting ring 1, a support component 5 for adjusting the tension of the filter bag installed on the connecting seat 4, an installation component 6 connected to the filter bag installed on the support component 5, and a transmission component 7 for moving the support component 5 on the connecting ring 1.

[0017] It should be noted that the transmission component 7 drives the expansion component 5 to move. The expansion component 5 is connected to the filter bag through the mounting component 6, thereby realizing the adjustment of the filter bag tension. The overall structure provides a basic framework for filter bag tension adjustment. The components work together to realize flexible adjustment of filter bag tension and ensure the normal operation of the dust collector.

[0018] The expansion assembly 5 includes a movable rod 51 slidably mounted on the connecting ring 1. A limiting rod 52 is fixedly installed inside the movable rod 51, and a groove 53 is formed inside the movable rod 51, in which the turntable 2 slides. Three limiting grooves 3 are provided and evenly distributed on the turntable 2. A through groove 8 is formed inside the connecting seat 4, in which the turntable 2 slides. When the turntable 2 rotates, the three evenly distributed limiting grooves 3 on it can make the movable rod 51 bear force evenly, ensuring the tension balance during the adjustment of the filter bag. The sliding design of the turntable 2 in the groove 53 and the through groove 8 makes the movement of the expansion assembly 5 stable and improves the adjustment accuracy. The limiting groove 3 cooperates with the limiting rod 52 in the movable rod 51. At the same time, the turntable 2 slides in the groove 53 of the movable rod 51 and the through groove 8 of the connecting seat 4, so that the movable rod 51 slides along the connecting ring 1, thereby expanding or contracting the filter bag.

[0019] The mounting assembly 6 includes a connecting plate 61 fixedly mounted on the movable rod 51. The connecting plate 61 has a clamping groove 62 inside and a connecting bolt 63 installed on the connecting plate 61. The edge of the filter bag is placed into the clamping groove 62, and the filter bag is fixed to the connecting plate 61 by the connecting bolt 63, so that the filter bag is connected to the spreading assembly 5. When the spreading assembly 5 moves, it drives the filter bag to change its tension. The design of the clamping groove 62 and the connecting bolt 63 makes the installation and disassembly of the filter bag convenient and quick, and the connection is firm. It can effectively transmit the force of the spreading assembly 5 and ensure the effectiveness of the filter bag tension adjustment.

[0020] An opening is provided on the connecting ring 1. The transmission assembly 7 includes a fixed plate 71 rotatably mounted on the opening, a worm gear 72 rotatably mounted on the fixed plate 71, and a worm wheel tooth 74 provided on the turntable 2. A motor 73 is mounted on the connecting ring 1, and the output end of the motor 73 is fixedly connected to the worm gear 72. A fixed sleeve 9 is fixedly mounted on the connecting ring 1, and the motor 73 is fixedly mounted on the fixed sleeve 9. When the motor 73 starts, its output end drives the worm gear 72 to rotate. The worm gear 72 and the worm wheel tooth 74 on the turntable 2 are driven by the worm gear 72 and the worm wheel tooth 74, which has a self-locking function to ensure that the turntable 2 is fixed in position after adjustment, so as to stabilize the filter bag tension. The fixed plate 71 and the fixed sleeve 9 provide stable support for the motor 73 and the worm gear 72, ensuring the reliable operation of the transmission assembly 7. The worm wheel tooth 74 meshes and drives the turntable 2 to rotate within the connecting ring 1, thereby driving the expansion assembly 5 to move and realize the adjustment of the filter bag tension.

[0021] Working Principle: The filter bag tension regulator of the negative pressure baghouse dust collector uses the connecting ring 1 as its basic frame and the transmission component 7 as its power source, driving the expansion component 5 to move. The expansion component 5 is connected to the filter bag through the mounting component 6, ultimately achieving flexible adjustment of the filter bag tension and ensuring the normal operation of the dust collector. The motor 73 starts, causing the turntable 2 to rotate inside the connecting ring 1 via the transmission component 7. When the turntable 2 rotates, the three evenly distributed limiting grooves 3 on it cooperate with the limiting rods 52 inside the moving rod 51. Simultaneously, the turntable 2 slides in the groove 53 of the moving rod 51 and the through groove 8 of the connecting seat 4. This design allows the moving rod 51 to slide along the connecting ring 1. Since the moving rod 51 of the expansion component 5 is connected to the mounting component 6, it drives the filter bag to expand or contract, thereby adjusting the filter bag tension. Furthermore, the three evenly distributed limiting grooves 3 ensure uniform force distribution on the moving rod 51, guaranteeing tension balance during filter bag adjustment. The sliding design of the turntable 2 within the groove 53 and through groove 8 stabilizes the movement of the expansion assembly 5, improving adjustment accuracy. The connecting plate 61 of the mounting assembly 6 is fixedly mounted on the moving rod 51. When installing the filter bag, the edge of the filter bag is placed into the clamping groove 62 inside the connecting plate 61, and then the filter bag is firmly fixed to the connecting plate 61 using the connecting bolts 63. In this way, when the expansion assembly 5 moves, the tension of the filter bag can be changed through the connecting plate 61. The design of the clamping groove 62 and the connecting bolts 63 makes filter bag installation and disassembly convenient and quick, and the connection is firm, effectively transmitting the force of the expansion assembly 5 and ensuring the effectiveness of filter bag tension adjustment. An opening is provided on the connecting ring 1, and the fixing plate 71 is rotatably mounted on the opening, while the worm gear 72 is rotatably mounted on the fixing plate 71. A motor 73 is fixedly mounted on the connecting ring 1 via a fixing sleeve 9. The output end of the motor 73 is fixedly connected to the worm gear 72, and the turntable 2 is provided with worm gear teeth 74. After the motor 73 starts, its output end drives the worm gear 72 to rotate. The worm gear 72 meshes with the worm gear teeth 74 on the turntable 2, thereby causing the turntable 2 to rotate within the connecting ring 1. The transmission method using the worm gear 72 and worm gear teeth 74 has a self-locking function, which can ensure that the turntable 2 is fixed in position after adjustment, thus stabilizing the filter bag tension. The fixing plate 71 and the fixing sleeve 9 provide stable support for the motor 73 and the worm gear 72, ensuring the reliable operation of the transmission assembly 7.
