Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, and more specifically, it relates to a dust collector filter bag that is easy to assemble and disassemble. Background Technology

[0002] In the daily maintenance of industrial dust collection systems, filter bags, as the core filtration element, need to be replaced regularly. Existing filter bag installation structures mostly use bolt fastening or clamp connection methods, which require special tools for disassembly and assembly. The operation steps are cumbersome and time-consuming, and are particularly inconvenient to operate in the narrow internal space of the dust collector, which seriously affects maintenance efficiency.

[0003] During the high-speed operation of dust removal equipment, the filter bags are subjected to continuous airflow impact and vibration. Existing fixing structures are mostly single locking methods, lacking multiple locking designs. After long-term use, they are prone to loosening and falling off, resulting in gaps between the filter bags and the installation port, causing dust leakage and affecting the dust removal effect.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a dust collector filter bag that is easy to assemble and disassemble, and has the following beneficial effects:

[0017] 1. This device achieves quick locking by having the limiting block on the vertical rod, driven by a rotating plate, engage with the limiting groove on the outer wall of the limiting sleeve. With the help of a push spring, the positioning block automatically springs into the positioning hole on the inner wall of the positioning sleeve to complete the positioning. During disassembly and assembly, only rotating the rotating plate is needed to complete the locking and unlocking operations, without the need for special tools, which greatly simplifies the operation process and improves the efficiency of filter bag replacement.

[0018] 2. This device achieves primary locking by having a locking block engage with the slot on the outer wall of the fixing ring. The locking plate at the top of the locking block simultaneously abuts against the outer wall of the fixing ring to form secondary locking. The limiting block is inserted into the limiting slot to lock the limiting sleeve and prevent it from sliding, forming tertiary protection. The multiple locking structures work together to effectively prevent the filter bag from loosening and falling off under the impact of airflow and vibration, ensuring the sealing performance of the dust removal system.

[0019] 3. This device achieves radial positioning by abutting the inner side of the fixed sleeve with the outer wall of the fixed sleeve. The guide block on the inner side of the limiting sleeve slides with the guide groove on the outer wall of the fixed sleeve to ensure accurate and smooth axial movement. At the same time, the pulley on the outer wall of the locking block rolls with the inner side of the limiting sleeve to effectively reduce sliding friction and wear, reduce fatigue wear of moving parts, and extend the service life of the equipment.

[0029] Please see Figures 1-5A dust collector filter bag that is easy to assemble and disassemble includes a fixing sleeve 1. The outer wall of the fixing sleeve 1 has an installation groove 2. The installation groove 2 is provided with multiple sets, and each set has a rotating shaft 3 fixed inside. Each set of rotating shafts 3 has a locking block 4 rotatably mounted on its outer wall. The fixing sleeve 1 has a fixing ring 5 inside. The outer wall of the fixing ring 5 has a locking groove 6. Each set of locking grooves 6 has multiple sets and abuts against each set of locking blocks 4. The bottom surface of the fixing ring 5 is fixed with a cage 7. The filter bag body 8 is connected to the cage 7. The outer wall of the fixing sleeve 1 is slidably provided with a limiting sleeve 9. A tension spring 10 is connected between the limiting sleeve 9 and the fixing sleeve 1. The outer wall of the limiting sleeve 9 has a limiting groove 11. The top of the fixing sleeve 1 is rotatably provided with a rotating plate 12. The bottom surface of the rotating plate 12 is fixed with a longitudinal rod 13. Each set of longitudinal rods 13 has a limiting block 14 fixed on its outer wall. The top surface of the rotating plate 12 is fixed with a positioning sleeve 15.

[0030] In this embodiment, the operator first keeps the limiting sleeve 9 in the upward pull state, so that the multiple sets of locking blocks 4 are kept in an outward flipped posture under the action of the torsion spring 26. Then, the fixing ring 5, which connects the cage bone 7 and the filter bag body 8, is aligned with the inner side of the fixing sleeve 1 and placed downward into the fixing sleeve 1, so that the outer wall of the fixing ring 5 abuts and is positioned against the abutting ring 21 on the inner side of the fixing sleeve 1. Then, the limiting sleeve 9 is pushed to stretch the tension spring 10. The limiting sleeve 9 slides downward and resets along the cooperation direction of the guide block 23 and the guide groove 24. The inner side of the limiting sleeve 9 abuts against the pulley 27 on the outer wall of the multiple sets of locking blocks 4. The rotation of the pulley 27 effectively reduces the sliding friction. Under the push of the limiting sleeve 9, the multiple sets of locking blocks 4 flip inward around the rotating shaft 3, overcoming the torsional force of the torsion spring 26, so that the locking blocks 4 are locked into the multiple sets of locking grooves 6 on the outer wall of the fixing ring 5. At the same time, the locking plate 22 at the top of the locking block 4 abuts against the outer wall of the fixing ring 5, so as to achieve a stable locking of the fixing ring 5. Subsequently, the rotating plate 12 is rotated, causing the limiting blocks 14 on the multiple sets of longitudinal rods 13 on the bottom surface of the rotating plate 12 to rotate and insert into the limiting grooves 11 on the outer wall of the limiting sleeve 9, locking the limiting sleeve 9 to prevent it from sliding up and down. Multiple sets of push springs 18 push multiple sets of positioning blocks 19 to abut against the positioning holes 20 to position the rotating plate 12, thus completing the installation of the filter bag body 8.

[0031] Please see Figures 3-5 As a further implementation of the overall equipment: a mounting plate 16 is fixedly provided on the top surface of the fixed sleeve 1, a mounting block 17 is fixedly provided on the top surface of the mounting plate 16, multiple sets of mounting blocks 17 are provided and push springs 18 are connected to the outer wall of each set of push springs 18, a positioning block 19 is fixedly provided at the top of each set of push springs 18, a positioning hole 20 is provided on the inner wall of the positioning sleeve 15, multiple sets of positioning holes 20 are provided and abut against multiple sets of positioning blocks 19 respectively.

[0032] An abutment ring 21 is fixedly provided on the inner side of the fixed sleeve 1, and the fixed ring 5 abuts against the outer wall of the abutment ring 21. Locking plates 22 are fixedly provided on the top of the multiple sets of locking blocks 4.

[0033] A guide block 23 is fixedly provided on the inner side of the limiting sleeve 9, and a guide groove 24 is provided on the outer wall of the fixing sleeve 1. Multiple sets of guide blocks 23 and guide grooves 24 are provided and are slidably connected.

[0034] Each of the multiple sets of mounting blocks 17 has a sliding hole 25, and each of the multiple sets of positioning blocks 19 is slidably connected to the sliding hole 25.

[0035] The top of the multiple positioning blocks 19 and the outer side of the multiple positioning holes 20 are all provided with rounded corners.

[0036] Each set of locking blocks 4 is connected to the rotating shaft 3 by a torsion spring 26.

[0037] The outer walls of multiple sets of locking blocks 4 are equipped with pulleys 27 that rotate. Multiple sets of pulleys 27 are provided and abut against the inner side of the limiting sleeve 9.

[0038] More specifically, when the filter bag needs to be disassembled and replaced, the rotating plate 12 is rotated. As the rotating plate 12 rotates, it drives multiple sets of mounting blocks 17 to rotate. The rounded corners on the outer sides of the multiple sets of positioning grooves abut against the top of the positioning blocks 19, causing the multiple sets of positioning blocks 19 to disengage from the positioning holes 20 and compress the push spring 18. As the rotating plate 12 continues to rotate, the multiple sets of positioning blocks 19 continue to slide along the inner wall of the positioning sleeve 15, causing the multiple sets of longitudinal rods 13 on the bottom surface of the rotating plate 12 to drive the limiting blocks 14 on them to rotate. The limiting block 14 is disengaged from the limiting groove 11 on the outer wall of the limiting sleeve 9, thus releasing the locking of the limiting sleeve 9. Then, the tension spring 10 is reset and pulls the limiting sleeve 9. The inner side of the limiting sleeve 9 is disengaged from the pulley 27 on the outer wall of the multiple sets of locking blocks 4. Under the torsional force of the torsion spring 26, the multiple sets of locking blocks 4 are rotated outward around the rotating shaft 3, causing the locking blocks 4 to disengage from the locking groove 6 on the outer wall of the fixing ring 5. At the same time, the locking plate 22 at the top of the locking block 4 also disengages from the outer wall of the fixing ring 5, releasing the fixing of the filter bag body 8.

[0039] In summary, during the use or operation of the overall equipment: the operator first keeps the limiting sleeve 9 in the upward position, so that the multiple sets of locking blocks 4 are kept in an outward flipped posture under the action of the torsion spring 26. Then, the fixing ring 5, which connects the cage bone 7 and the filter bag body 8, is aligned with the inside of the fixing sleeve 1 and placed downward into the fixing sleeve 1, so that the outer wall of the fixing ring 5 abuts against the abutting ring 21 on the inner side of the fixing sleeve 1 for positioning. Then, the limiting sleeve 9 is pushed to stretch the tension spring 10. The limiting sleeve 9 slides downward and resets along the cooperation direction of the guide block 23 and the guide groove 24. The inner side of the limiting sleeve 9 abuts against the pulley 27 on the outer wall of the multiple sets of locking blocks 4. The rotation of the pulley 27 effectively reduces sliding friction. Under the push of the limiting sleeve 9, the multiple sets of locking blocks 4 flip inward around the rotating shaft 3, overcoming the torsional force of the torsion spring 26, so that the locking blocks 4 are locked into the multiple sets of locking grooves 6 on the outer wall of the fixing ring 5. At the same time, the locking plate 22 at the top of the locking block 4 abuts against the outer wall of the fixing ring 5, realizing the stable locking of the fixing ring 5. Subsequently, the rotating plate 12 is rotated, causing the limiting blocks 14 on the multiple sets of longitudinal rods 13 on the bottom surface of the rotating plate 12 to rotate and insert into the limiting grooves 11 on the outer wall of the limiting sleeve 9, locking the limiting sleeve 9 to prevent it from sliding up and down. Multiple sets of push springs 18 push multiple sets of positioning blocks 19 to abut against the positioning holes 20 to position the rotating plate 12, thus completing the installation of the filter bag body 8.

[0040] When the filter bag needs to be disassembled and replaced, rotate the rotating plate 12. When the rotating plate 12 rotates, it drives multiple sets of mounting blocks 17 to rotate. The rounded corners on the outer side of the multiple sets of positioning grooves abut against the top of the positioning blocks 19, causing the multiple sets of positioning blocks 19 to disengage from the positioning holes 20 and squeeze the push spring 18. When the rotating plate 12 continues to rotate, the multiple sets of positioning blocks 19 continue to slide along the inner wall of the positioning sleeve 15. At the same time, the multiple sets of vertical rods 13 on the bottom surface of the rotating plate 12 drive the limit blocks 14 on them to rotate, causing the limit blocks 14 to disengage from the limit grooves 11 on the outer wall of the limit sleeve 9, releasing the lock on the limit sleeve 9. Then, the tension spring 10 returns to its original position and pulls the limit sleeve 9. The inner side of the limit sleeve 9 disengages from the pulleys 27 on the outer wall of the multiple sets of locking blocks 4. Under the torsional force of the torsion spring 26, the multiple sets of locking blocks 4 rotate outward around the rotating shaft 3, causing the locking blocks 4 to disengage from the locking grooves 6 on the outer wall of the fixing ring 5. At the same time, the locking plate 22 at the top of the locking block 4 also disengages from the outer wall of the fixing ring 5, releasing the fixation on the filter bag body 8.

These will not be elaborated on here. For all the fixed connections mentioned above, welding is the preferred option.
