[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model can solve the problem that the pulse cleaning is too strong or insufficient and the size cannot be adjusted to achieve the appropriate impact by setting an adjustable nozzle mechanism. Excessive cleaning may cause additional energy consumption and more particulate matter to be released in the air, resulting in increased dust accumulation on the surface of the filter bag and affecting the performance of the system. The air flows into the interior through the internal duct of the outer shell, and then the filter bag at the bottom is pulse-cleaned through the air outlet at the bottom. When adjustment is needed, the hydraulic rod is controlled to be extended and retracted through the external air pump and the control end to push the rotating disk to rotate. During rotation, the top of the internal connecting column slides in the card groove on the rotating disk, and then the bottom end of the connecting column is installed in the slide groove on the base plate to slide to adjust the gas flow rate to clean the filter bag, thereby effectively improving the cleaning of the filter bag, increasing the gas injection area, and facilitating improving work efficiency.

[0016] 2. The vibration cleaning mechanism and telescopic tube can solve the problem that dust is likely to remain at the bottom of the filter bag during cleaning, which causes dust on the bottom surface of the filter bag to accumulate faster, resulting in increased resistance, affecting the performance of the dust collector, and possibly shortening the service life of the filter bag. The connecting block on the telescopic end of the electric push rod is connected to the connecting plate to drive the connecting plate to move up and down. When moving, it will be fixed by the annular card plate on the outer side of the inner tube of the telescopic tube, and then connected by the joint plate between the two annular card plates to fix it with the outer connecting plate, which can better drive multiple groups of telescopic tubes to slide up and down to improve the unified lifting and lowering, and the nozzle is lowered to the temporal part of the filter bag for precise cleaning. While descending, the first support plate will be driven to press down through the fixed block at the bottom of the connecting plate. After pressing down, it will rebound through the spring on the second support plate to generate vibration to clean the internal filter bag, and shake off the firm particles and dust, thereby effectively improving the bottom that cannot be washed away by the pulse for another cleaning, so as to improve the cleaning of the filter bag.

[0017] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] By fixing the electric push rod 501 on the top wall of the dust removal box 1, the bottom device can be driven to slide better, and the connecting block 502 fixed at the bottom of the dust removal box 1 is connected to the connecting plate 503, and then the bottom end of the inner cylinder of the telescopic tube 12 is fixed by the annular clamping plate 504, and then the joint plate 505 is fixed to the inside of the two annular clamping plates 504 to achieve unified fixation, and the outer side of the annular clamping plate 504 is fixed to the inner side wall of the connecting plate 503, and the adjustable nozzle mechanism 4 is driven to rise and fall through the telescopic tube 12, and extends into the inside of the filter bag 6 to clean, so as to adjust the cleaning area.

[0037] It should be noted that the utility model is a pulse cleaning structure for a bag dust collector. First, gas is pumped into the interior of the air bag 9 through an external air pump. During cleaning, the gas will be transferred to the interior of the delivery pipe 3 through the adapter 8 at the top. During the transfer, the electromagnetic pulse valve 7 will be opened through the outer control end to allow the gas to enter the interior of the delivery pipe 3. The gas will enter the interior of the adjustable nozzle mechanism 4 through the telescopic tube 12 at the bottom to clean the filter bag 6.

[0038] When adjusting the gas, it is necessary to start the hydraulic rod 409 through the external control end to extend and retract.
