DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: a pulse valve of bag dust collector, including pulse valve base 1 and the pulse valve upper cover 2 of insertion in pulse valve base 1, multiple drive gears 3 are rotationally connected in pulse valve base 1, installation tooth ring 4 is rotationally connected in pulse valve base 1, the drive gear 3 is engaged with installation tooth ring 4, and the side of drive gear 3 is engaged with limit rack 5, with the rotation of drive gear 3, limit rack 5 moves towards the position of the center of pulse valve base 1, and limit groove is opened in the pulse valve upper cover 2 and is adapted with limit rack 5.

[0025] Specific implementation, when installing pulse valve, pulse valve upper cover 2 is aligned with pulse valve base 1 and is inserted.This time, multiple drive gears 3 in pulse valve base 1 are in initial state.

[0026] When pulse valve upper cover 2 and pulse valve base 1 need to be fixed, one of drive gears 3 is rotated.Drive gear 3 is engaged with installation tooth ring 4, and the rotation of drive gear 3 will drive installation tooth ring 4 to rotate, and limit rack 5 engaged with installation tooth ring 4 starts to move.Limit rack 5 moves towards the position of the center of pulse valve base 1, and when limit rack 5 moves to certain position, it will cooperate with the limit groove opened in pulse valve upper cover 2.

[0027] The limiting rack 5 is inserted into the limiting groove, which plays a role in fixing the pulse valve upper cover 2 and the pulse valve base 1, preventing the two from separating during operation. When the pulse valve needs to be disassembled, the drive gear 3 is only needed to be rotated in the reverse direction, so that the limiting rack 5 is withdrawn from the limiting groove, and the pulse valve upper cover 2 can be removed from the pulse valve base 1.

[0028] With reference to Figure 2 , a plurality of drive gears 3 are distributed in a circular array at equal intervals with the central axis of the pulse valve base 1 as the center.

[0029] In specific implementation, the arrangement is convenient for fixing the pulse valve upper cover 2 in multiple directions.

[0030] With reference to Figure 5 , one of the drive gears 3 is connected with a drive shaft 6, one end of the drive shaft 6 extends to the outside of the pulse valve upper cover 2, the pulse valve upper cover 2 is connected with a mounting frame 7, the mounting frame 7 is rotatably connected with a connecting ratchet 8, the connecting ratchet 8 is connected with the drive shaft 6, the mounting frame 7 is rotatably connected with a limiting pawl 9, the limiting pawl 9 is meshed with the connecting ratchet 8, the mounting frame 7 is connected with a compression spring 10, and the other end of the compression spring 10 is connected with the limiting pawl 9.

[0031] In specific implementation, when one of the drive gears 3 is rotated to realize the fixing process of the pulse valve upper cover 2 and the pulse valve base 1 through the drive shaft 6, the drive shaft 6 connected with the drive gear 3 is rotated. One end of the drive shaft 6 extends to the outside of the pulse valve upper cover 2 and is connected with the connecting ratchet 8 in the mounting frame 7, thereby driving the connecting ratchet 8 to rotate. During the rotation of the connecting ratchet 8 driven by the drive shaft 6, the connecting ratchet 8 can only rotate in one direction. This is because when the connecting ratchet 8 tries to rotate in the reverse direction, the limiting pawl 9 will be clamped in the tooth groove of the connecting ratchet 8, preventing it from rotating in the reverse direction. In this way, it is ensured that the drive gear 3 will not be reversed due to accidental external force or vibration after completing the fixing operation of the pulse valve upper cover 2 and the pulse valve base 1, thereby ensuring that the limiting rack 5 is always in a fixed state matched with the limiting groove of the pulse valve upper cover 2.

[0032] With reference to Figure 5 , the limiting pawl 9 is connected with a connecting shaft 11, and one end of the connecting shaft 11 extends to the outside of the mounting frame 7.

[0033] In specific implementation, the connecting shaft 11 is arranged to facilitate the rotation of the limiting pawl 9 and the application of force to the limiting pawl 9.

[0034] With reference to Figure 5 , the connecting shaft 11 is connected with a first force applying plate 12, and an anti-skid sleeve is sleeved on the outside of the first force applying plate 12.

[0035] In specific implementation, the first force applying plate 12 is arranged to facilitate the rotation of the connecting shaft 11.

[0036] Reference Figure 5 One end of the drive shaft 6 extends to the outside of the mounting frame 7 and is connected with the second force plate 13, and the second force plate 13 is integrally formed with anti-skid lines.

[0037] Specifically, the second force plate 13 is arranged to facilitate the rotation of the drive shaft 6, so that the drive shaft 6 can rotate better.

[0038] Reference Figure 1 A plurality of limiting grooves are formed on the outside of the pulse valve base 1, and the size of the limiting grooves is adapted to the limiting rack 5.

[0039] In specific implementation, the limiting grooves are arranged to facilitate the sliding of the limiting rack 5.

[0040] Reference Figure 5 The thickness of the drive gear 3 is equal to the sum of the thicknesses of the mounting tooth ring 4 and the limiting rack 5.

[0041] In specific implementation, this arrangement facilitates the drive gear 3 to drive both the mounting tooth ring 4 and the limiting rack 5.

[0042] Working principle: when installing the pulse valve, the pulse valve cover 2 is aligned with the pulse valve base 1 for insertion. At this time, the plurality of drive gears 3 in the pulse valve base 1 are in the initial state.

[0043] When it is necessary to fix the pulse valve cover 2 and the pulse valve base 1, one of the drive gears 3 is rotated. Since the drive gear 3 is connected with the mounting tooth ring 4 in meshing, the rotation of the drive gear 3 will drive the mounting tooth ring 4 to rotate, and the limiting rack 5 meshing with the mounting tooth ring 4 starts to move. The limiting rack 5 moves to a position close to the center of the pulse valve base 1. When the limiting rack 5 moves to a certain position, it cooperates with the limiting groove formed on the pulse valve cover 2;

[0044] After the limiting rack 5 is inserted into the limiting groove, it plays a role in fixing the pulse valve cover 2 and the pulse valve base 1, preventing them from separating during work. When it is necessary to disassemble the pulse valve, the drive gear 3 is only needed to be rotated in the opposite direction to make the limiting rack 5 exit from the limiting groove, so that the pulse valve cover 2 can be removed from the pulse valve base 1;

[0045] When one of the driving gears 3 is rotated to fix the pulse valve cover 2 and the pulse valve base 1, the driving shaft 6 connected to the driving gear 3 is rotated. One end of the driving shaft 6 extends to the outside of the pulse valve cover 2 and is connected to the connecting ratchet 8 in the mounting frame 7, thereby rotating the connecting ratchet 8. During the rotation of the connecting ratchet 8 by the driving shaft 6, the connecting ratchet 8 can only rotate in one direction. This is because when the connecting ratchet 8 tries to rotate in the opposite direction, the limiting pawl 9 will be clamped in the tooth groove of the connecting ratchet 8, preventing it from rotating in the opposite direction. In this way, it is ensured that the driving gear 3 will not be reversed after completing the fixing operation of the pulse valve cover 2 and the pulse valve base 1 due to accidental external force or vibration, thereby ensuring that the limiting rack 5 is always in a fixed state of cooperation with the limiting groove of the pulse valve cover 2.
