The opening and closing of each pulse valve are individually controlled, and all pulse valves are made to work synchronously by adjusting the opening and closing delay time of each pulse valve, so as to achieve the same blowing effect as that of a single large-diameter pulse valve. A large-diameter pulse valve is replaced by a combination of multiple small-diameter submerged pulse valves, and the investment cost is low because the small-diameter submerged pulse valve is cheap. Moreover, the technology of small-diameter submerged pulse valves is mature, the pulse valve has a long life, and the cost of replacing the diaphragm is low.

[0030] When assembling the pulse valve 6, fit the mounting plate 13 to both sides of the upper part of the gas distribution box 7, and use the fixing bolts 14 to fix the connection through the internal threads. Set the blowing pipe 11 at the lower part of the pulse valve 6, and ensure that it correctly penetrates the upper part of the dust removal box 1; externally fix the connecting piece 8 to the pulse valve 6, and the connecting plate 9 is sleeved on the outside of the blowing pipe 11. By setting the connecting piece 8, the pulse valve 6 and the blowing pipe 11 can be quickly installed;

[0031] By setting a mounting plate 13 on the air distribution box 7 and fixing the mounting plate 13 by fixing bolts 14, a close fit with the air distribution box 7 can be achieved, thereby shortening the installation time. By setting a sealing ring at the junction of the blowing pipe 11 and the air distribution box 7, the sealing of the device is ensured, and the blowing effect is good.

[0032] Reference Figure 1 and Figure 3 The dust removal assembly includes a nozzle 17, which is fixedly connected to the lower part of the blowing pipe 11. A spring 15 is provided inside the blowing pipe 11, and a sliding disk 20 is provided at the lower part of the spring 15. A blowing rod 16 is fixedly connected to the lower part of the sliding disk 20. The top of the sliding disk 20 is connected to the inner wall of the blowing pipe 11 through the spring 15, and the outer side of the sliding disk 20 is slidably connected to the inner wall of the nozzle 17;

[0033] A filter plate 18 is fixedly connected to the inside of the dust removal box 1, and the bottom of the nozzle 17 passes through the filter plate 18. A dust bag 19 corresponding to the nozzle 17 is fixedly connected to the lower part of the filter plate 18, and both ends of the filter plate 18 are connected to the inner wall of the dust bag 19;

[0034] When dust removal is required, the device first allows the dust to enter the dust removal box 1 through the dust inlet pipe 3, and removes dust through the dust bag 19 in the dust removal box 1, so that the dust removed enters the ash hopper 10, and then compresses the gas in the air bag 5 on the fixed plate 4 through the pulse valve 6, so that the gas enters the nozzle 17 through the blowing pipe 11; the pressure of the gas will drive the sliding disk 20 to move downward in the nozzle 17, and the downward movement of the sliding disk 20 will drive the blowing rod 16 to enter the dust bag 19, and then the gas enters the through hole in the blowing rod 16 through the vent 21;

[0035] The gas is sprayed to various parts of the dust bag 19 through the jet holes, so as to remove the dust on the dust bag 19, and then the sliding plate 20 drives the blowing rod 16 to enter the nozzle 17 through the elastic force of the spring 15, and finally the excess gas is discharged through the clean air outlet, so that the bag dust collector can be fully dusted.

[0036] Reference Figure 1 , Figure 3 and Figure 4The left part of the dust removal box 1 is fixedly connected with a dust inlet pipe 3, the blowing rod 16 is slidably connected to the inside of the nozzle 17, the four corners of the bottom of the dust removal box 1 are fixedly connected with a bracket 2, the right side of the pulse valve 6 is fixedly connected with a detector 12, the inside of the blowing rod 16 is provided with a vent hole 21, and the air distribution box 7 is arranged on the left side of the dust removal box 1;

[0037] By setting up the dust inlet pipe 3, the dust enters the dust removal box 1, and the blowing rod 16 slides inside the nozzle 17, so that the blowing rod 16 can enter the dust bag 19, and then the gas enters the through hole in the blowing rod 16 through the air vent 21, and the gas is sprayed to various parts of the dust bag 19 through the jet hole, and the dust removal box 1 is supported by setting the bracket 2, and the pulse valve 6 is detected by setting the detector 12, and the air vent 21 is set to allow the gas to enter the through hole in the blowing rod 16 through the air vent 21; the gas is sprayed to various parts of the dust removal bag 19 through the jet hole, and the dust-containing airflow entering the dust collector can be guided by the air distribution box 7 on the left side of the dust removal box 1, ensuring that the dust removal operation can be carried out efficiently.

[0038] Working principle: When using this device, fit the mounting plate 13 to both sides of the upper part of the gas distribution box 7, and use the fixing bolts 14 to fix the connection through the internal threads. Set the blowing pipe 11 at the lower part of the pulse valve 6 and ensure that it correctly penetrates the upper part of the dust removal box 1. The external fixed connection connector 8 is connected to the pulse valve 6, and the connecting plate 9 is set on the outside of the blowing pipe 11 to ensure a firm connection.

[0039] During operation, dust enters the dust removal box 1 through the dust inlet pipe 3, and is first removed by the dust removal bag 19 in the dust removal box 1, so that the removed dust enters the ash hopper 10, and then the gas in the air bag 5 is compressed by the pulse valve 6, and then the gas enters the nozzle 17 through the blowing pipe 11;

[0040] The pressure of the gas drives the sliding plate 20 to move downward in the nozzle 17, and then the sliding plate 20 drives the blowing rod 16 to enter the dust bag 19, and the gas enters the through hole in the blowing rod 16 through the vent hole 21; the gas is sprayed to various parts of the dust bag 19 through the spray hole to remove the dust on the dust bag 19;

[0041] The elastic force of the spring 15 causes the sliding disk 20 to drive the blowing rod 16 into the nozzle 17, and the over-settled gas is discharged through the clean air outlet, so that the bag dust collector can be fully dust-removed, thereby improving the dust removal effect.
