[0002] The pulse jet filter cartridge dust collector is a high-efficiency dry dust removal device mainly used in the field of industrial dust filtration. It separates dust particles in dust-laden gas through three stages: "filtration-cleaning-collection". Its core component is the filter cartridge, which captures fine dust particles by relying on the dense sieve structure on its surface. The equipment uses pulse jet cleaning technology for automatic cleaning.

[0003] However, existing pulse jet cartridge dust collectors require multiple bolts for alignment and installation during cartridge replacement, which takes a considerable amount of time. Therefore, those skilled in the art have provided a cartridge replacement structure for pulse jet cartridge dust collectors to solve the problems mentioned in the background section. Utility Model Content

[0012] This utility model provides a filter cartridge replacement structure for a pulse jet filter cartridge dust collector, which has the following advantages compared with the prior art: 1. This design provides a filter cartridge replacement structure for a pulse jet filter cartridge dust collector. By incorporating a locking mechanism, the screw support sleeve can be easily released from its compression limit on the locking block mounting bracket during filter cartridge body replacement. One end of the locking block mounting bracket retracts, allowing the locking block on the outside of the mounting bracket to disengage from the positioning mounting sleeve, thus releasing the lock on the filter cartridge body. A new filter cartridge body can then be replaced. This convenient locking and unlocking of the positioning mounting sleeve simplifies the filter cartridge body replacement operation and enables quick disassembly and installation.

[0013] 2. The filter cartridge replacement structure for a pulse jet dust collector designed in this paper features a positioning connection mechanism. Both the positioning threaded rod and the connecting plate serve to reinforce and limit the movement, preventing the filter cartridge body from being installed crookedly or loosely. At the same time, after the limit nut and the positioning threaded rod are threaded together, the corresponding surface of the limit nut is tightly against the mounting pad, ensuring that the filter cartridge body and the pulse jet dust collector mounting plate are aligned. This provides uniform and sufficient clamping force to the sealing gasket, ensuring a good sealing effect, and the disassembly and replacement are simple to operate. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This utility model provides a filter cartridge replacement structure for a pulse jet filter cartridge dust collector, including a pulse jet filter cartridge dust collector mounting plate 1, connecting brackets 2 fixed on both sides of the pulse jet filter cartridge dust collector mounting plate 1, a mounting pad 3 fixed on the top of the pulse jet filter cartridge dust collector mounting plate 1, a locking mechanism 4 provided on the top of the mounting pad 3, a positioning mounting sleeve 7 connected to the bottom outer side of the locking mechanism 4, a filter cartridge body 5 fixed to the bottom of the positioning mounting sleeve 7, and a positioning connection mechanism 6 provided on the top of the filter cartridge body 5; The locking mechanism 4 includes a fixed housing 41, a rotating frame 42 rotatably connected inside the fixed housing 41, a rotating threaded rod 45 fixed at the bottom of the rotating frame 42, a threaded support sleeve 46 threadedly connected to the outside of the rotating threaded rod 45, a support slider 47 fixed to the outside of the threaded support sleeve 46, a locking block mounting bracket 43 fixed at the bottom of the fixed housing 41, a fixed limiting sleeve 44 installed at the bottom of the fixed housing 41, a limiting groove opened inside the fixed limiting sleeve 44, the size of the groove being adapted to the size of the support slider 47, the fixed housing 41 and the mounting pad 3 being fixedly connected, a locking groove adapted to the size of the locking block mounting bracket 43 being opened inside the positioning mounting sleeve 7, the positioning mounting sleeve 7 being fixed to the top of the filter cartridge body 5, and a connecting groove adapted to the size of the positioning mounting sleeve 7 being opened inside the pulse filter cartridge dust collector mounting plate 1.

[0018] The positioning connection mechanism 6 includes a positioning threaded rod 61, with a limit nut 62 threadedly connected to the outer side of the positioning threaded rod 61. A positioning handle pad 63 is fixed to the outer side of the limit nut 62. A connecting plate 64 is fixed to the top of the outer side of the filter cartridge body 5. A limit frame 66 is fixed to the outer side of the pulse filter cartridge dust collector mounting plate 1. A positioning frame 65 is installed on the outer side of the limit frame 66. The positioning threaded rod 61 and the filter cartridge body 5 are fixedly connected. The corresponding surface of the positioning frame 65 is in contact with the connecting plate 64. Both the pulse filter cartridge dust collector mounting plate 1 and the mounting pad 3 have through holes inside, and the size of the through holes is adapted to the size of the positioning threaded rod 61.

[0019] The working principle of this utility model is as follows: With the locking mechanism 4, when replacing the filter cartridge body 5, the user can insert a flathead screwdriver into the groove on the top surface of the rotating frame 42, rotating the rotating frame 42 to drive the rotating threaded rod 45 to rotate. The threaded support sleeve 46 on the outside of the rotating threaded rod 45 can rise and fall, allowing the support slider 47 on the outside of the threaded support sleeve 46 to move vertically within the fixed limiting sleeve 44. Since the locking block mounting bracket 43 is an elastic element, the locking block on the outside of the locking block mounting bracket 43 can engage with the positioning mounting sleeve 7 because the threaded support sleeve 46 limits the inner wall of the locking block mounting bracket 43. Therefore, when the threaded support sleeve 46 moves upward, the squeezing limitation of the threaded support sleeve 46 on the locking block mounting bracket 43 can be released, and one end of the bottom of the locking block mounting bracket 43 retracts, allowing the locking block on the outside of the locking block mounting bracket 43 to disengage from the positioning mounting sleeve 7, releasing the lock on the filter cartridge body 5. Then, a new filter cartridge body 5 can be replaced, and the locking and unlocking of the positioning mounting sleeve 7 can be easily completed. This design simplifies the replacement of the filter cartridge body 5, enabling quick disassembly and installation. With the positioning connection mechanism 6, when the filter cartridge body 5 is installed at the bottom of the pulse jet filter dust collector mounting plate 1, the corresponding surface of the connecting plate 64 on the outside of the filter cartridge body 5 aligns with the corresponding surface of the positioning frame 65. Furthermore, the positioning threaded rod 61 at the top of the connecting plate 64 can penetrate the pulse jet filter dust collector mounting plate 1 and the mounting pad 3. Then, a limit nut 62 is threadedly connected to the positioning threaded rod 61. A positioning handle pad 63 is provided on the outside of the limit nut 62 for easy operation. Both the positioning threaded rod 61 and the connecting plate 64 serve to reinforce and limit the position, preventing the filter cartridge body 5 from being installed crookedly or loosely. Simultaneously, after the limit nut 62 and the positioning threaded rod 61 are threadedly connected, the corresponding surface of the limit nut 62 is tightly against the mounting pad 3, ensuring that the filter cartridge body 5 and the pulse jet filter dust collector mounting plate 1 are properly aligned. This provides uniform and sufficient clamping force to the sealing gasket, ensuring a good sealing effect and simplifying disassembly and replacement.

[0020] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
