[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0041] like Figures 1-4 As shown, this embodiment provides a pulse valve airflow regulating device, including a pulse valve body 1. The pulse valve body 1 adopts existing technology, so it will not be described in detail. Refer to publication number CN222315959U - Chinese Utility Model Patent for an Electromagnetic Pulse Valve or publication number CN222559326U - Chinese Utility Model Patent for an Electromagnetic Pulse Valve. The pulse valve body 1 has an air outlet pipe 11. The end of the air outlet pipe 11 away from the pulse valve body 1 passes through the circumference of the partition plate 2 of the bag filter and has a first external thread 110. The partition plate 2 divides the inner cavity of the dust collector into a clean chamber and a dirty chamber. The pulse valve body 1 is located in the clean chamber. Figure 2 , Figure 3As shown, the pulse valve gas flow regulating device further comprises a flow guiding mechanism 3. The flow guiding mechanism 3 comprises a first ring 31, a second ring 32 and a third ring 33, which are coaxially connected in sequence by a fastener 4. The first ring 31, the second ring 32 and the third ring 33 are circumferentially arranged coaxially and each are provided with a plurality of through holes 30. The fastener 4 comprises a plurality of second bolts 41, which correspond one-to-one with the plurality of through holes 30. The second bolts 41 are sequentially threaded through the through holes 30 of the third ring 33, the through holes 30 of the second ring 32 and the through holes 30 of the first ring 31, and are screwed with a third nut. The inner diameters of the first ring 31, the third ring 33 and the second ring 32 increase in sequence, and the inner circumference of the first ring 31 is provided with a first internal thread (not shown), which is screwed with the first external thread 110. The inner circumference of the second ring 32 and one side wall of the first ring 31 and one side wall of the third ring 33 form an annular groove 34. The annular groove 34 is embedded with a rotating ring 35, and the inner circumference of the rotating ring 35 is coaxially provided with a vertical pipe 350, which is connected with at least one L-shaped pipe 36. The L-shaped pipe 36 comprises a horizontal pipe 361, an outer pipe 362 and an L-shaped pipe 363. One end of the horizontal pipe 361 is connected with the vertical pipe 350, and the other end of the horizontal pipe 361 is circumferentially provided with a fifth external thread 3610. One end of the L-shaped pipe 363 is circumferentially provided with a sixth external thread 3631, and the inner wall of the outer pipe 362 is circumferentially provided with a third internal thread (not shown), which is screwed with the fifth external thread 3610 and the sixth external thread 3631, respectively. The length of one end of the L-shaped pipe 36 is adjusted as a whole.

[0042] One end of the air outlet pipe 11 penetrates the partition plate 2 of the cloth bag dust collector and is firmly mounted thereon, the first external thread 110 is tightly screwed with the first internal thread, ensuring that the drainage mechanism 3 can be conveniently disassembled and assembled on the air outlet pipe 11. The air outlet port of the vertical pipe 350 is accurately positioned directly above one filter cartridge and maintains a proper distance, the inner ring of the rotating ring 35 is coaxially arranged with the vertical pipe 350, and the vertical pipe 350 is at least connected with one L-shaped pipe 36. The L-shaped pipe 36 can be flexibly rotated until its air outlet port is aligned directly above another filter cartridge, also maintaining a certain distance, and the number of L-shaped pipes 36 can be flexibly increased according to the actual layout of the filter cartridges. When the pulse valve is driven to operate, it will instantaneously release high-pressure gas, which will pass through the air outlet pipe 11, the vertical pipe 350 or the L-shaped pipe 36 in turn and be sprayed out. The spraying of high-pressure gas not only causes the cloth bag on the filter cartridge to vibrate and swing, thereby achieving the cleaning of the cloth bag, but also drives the surrounding gas to flow into the filter cartridge at the moment when the high-pressure gas is sprayed out of the vertical pipe 350 or the L-shaped pipe 36. Compared with the prior art, the structure has the following advantages: a single pulse valve can realize the distribution of air flow through the rotatable vertical pipe 350 and L-shaped pipe 36, can cover multiple filter cartridges at the same time, can significantly reduce the number of pulse valves used, and can thereby reduce the cost of equipment and the complexity of maintenance. In addition, the ingenious design of the rotating ring 35, the vertical pipe 350 and the L-shaped pipe 36 makes the blowing angle freely adjustable, ensuring that the air flow can be accurately aligned with the filter cartridges at different positions and perfectly adapt to various dust collector layouts.

[0043] The side wall of the third ring 33 is provided with a threaded hole (not shown) along the axial direction, and the first bolt 37 (not shown) is screwed into the threaded hole and abuts against the rotating ring 35. By tightening the first bolt 37 to abut against the rotating ring 35, the blowing direction of the vertical pipe 350 or the L-shaped pipe 36 can be locked, avoiding angle deviation caused by air flow impact or vibration, and ensuring that the dust removal air flow is always aligned with the center of the filter bag. The pulse valve body 1 also has an air inlet pipe 12, one end of which away from the pulse valve body 1 is connected with an air tank (not shown). The air tank adopts the prior art, and a large amount of compressed air needs to be instantaneously released when the pulse valve blows. The air tank as an energy storage buffer container can avoid direct consumption of the pressure of the main gas source pipeline, preventing the system pressure from suddenly dropping. When multiple pulse valves work at the same time or alternately, the air tank can maintain stable pressure, ensuring that the blowing force of each valve is consistent and avoiding incomplete dust removal due to insufficient air pressure. For example Figure 4As shown, the pulse valve gas flow regulating device further comprises a receiving pipe 5 and a first nut 51, one side of the first nut 51 coaxially butts against a limiting ring 52. A second internal thread (not shown) is circumferentially arranged on the inner wall of the air inlet pipe 12. A third external thread 53 and a fourth external thread 54 are circumferentially arranged on the outer wall of the two ends of the receiving pipe 5, respectively. The third external thread 53 is screwed with the second internal thread. The gas pocket has a first connecting pipe 6, and the outer wall of one end of the first connecting pipe 6 coaxially abuts against a ring 61. The first nut 51 is sleeved on the first connecting pipe 6, and the first nut 51 is screwed with the fourth external thread 54, and the ring 61 is embedded between the limiting ring 52 and one end of the receiving pipe 5. By screwing the third external thread 53, the fourth external thread 54 and the first nut 51, the assembly or disassembly of the gas pocket and the pulse valve can be completed without welding or complex tools, and the difficulty of manual operation is reduced. The pulse valve gas flow regulating device further comprises a flexible ring 62, which is arranged between the limiting ring 52 and one end of the receiving pipe 5. The pulse valve gas flow regulating device further comprises a threaded flange 7 and a second nut 71. The air outlet pipe 11 has a stepped structure 111, the threaded flange 7 is screwed with the first external thread 110, the threaded flange 7 abuts against the partition plate and the stepped structure 111, respectively, and the second nut is screwed with the first external thread and abuts against the partition plate
