[0040] like Figures 1 to 6As shown in the figure, the ash bucket connecting assembly 41 of this utility model includes a pressure relief valve 410, an air pipe 412, and an ash bucket sealing end pipe 44; one end of the pressure relief valve 410 is connected to the outlet of the funnel 40 through a first flange 411, and the other end of the pressure relief valve 410 is connected to one end of the air pipe 412 through a second flange 413; the ash storage bucket 42 includes a bucket body 421 and a bucket cover 420 detachably connected thereto, the bucket cover 420 is provided with an inlet, the bucket cover 420 inside the inlet is provided with an ash bucket sealing end pipe 44, the outer wall of the ash bucket sealing end pipe is provided with at least two rings of ash bucket protrusions 440, and an ash bucket clamp 441 is provided between the two ash bucket protrusions 440 to fix one end of the dust collection bag 45; and the other end of the air pipe 412 extends into the dust collection bag 45 from the inlet and the ash bucket sealing end pipe 44. In this embodiment, the ash storage device 4 also includes a counterweight, which is placed inside the dust collection bag 45 to ensure that the dust collection bag 45 does not move arbitrarily.

[0041] In a preferred embodiment, a handle 4200 is provided on the outer side of the bucket lid 420; a dust bucket hanging plate 43 is provided on the movable bracket 1, on which the handle 4200 is hung; furthermore, the dust bucket hanging plate 43 is detachably mounted on the movable bracket 1 so that the position of the dust bucket hanging plate 43 can be adjusted according to actual needs, making the replacement of the dust collection bag 45 more convenient. Specifically, the dust bucket hanging plate 43 includes a hanging plate body, one end of which is provided with a U-shaped hook, and through holes are provided on the hanging plate body to reduce weight.

[0042] When replacing the dust collection bag 45, first close the pressure relief valve 410 to seal the device. Then, lift the ash storage bin 42 and place it on the ground. Next, open the buckle 422 connecting the bin cover 420 and the bin body 421, and hang the handle 4200 on the bin cover 420 on the ash bin hanging plate 43. At this time, the dust collection bag 45 is in the unfolded state. When replacing it, first remove the dust collection bag 45 from the bin body 421, then remove the rubber strip, loosen the ash bin clamp 441, and remove the dust collection bag 45 while putting on a new dust collection bag 45. This ensures the sealing of the dust collection bag 45 during replacement and prevents dust from flying out of the dust collection bag 45.

[0043] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the dust removal equipment of this utility model also includes a pulse cleaning device 5. The pulse cleaning device 5 includes a back-blowing horn 53, a compressed air tank 50 located outside the filter cartridge, a differential pressure transmitter 52, and a pulse controller 51. The back-blowing horn 53 is located inside the filter cartridge chamber 10 near the filter cartridge outlet 102. The compressed air tank 50 is connected to the filter cartridge chamber 10 and electrically connected to the pulse controller 51. The pulse controller 51 is also electrically connected to the differential pressure transmitter 52. The differential pressure transmitter 52 is used to detect the pressure difference between the inner wall and the surface of the filter. When the pressure difference is greater than a preset value, the pulse controller 51 opens the compressed air tank 50 and releases compressed gas to back-blow the filter cartridge 8 to remove dust from the surface of the filter cartridge 8. In addition, the differential pressure transmitter 52 can be conveniently and quickly connected via a differential pressure quick-connect air pipe connector.

[0044] like Figures 1 to 6 As shown in the figure, when the dust removal equipment for pharmaceutical machinery of this utility model is used, it can be connected to a dust removal system. Under the negative pressure drive of the fan of the user's dust removal system, the dust-laden gas is drawn into the filter cartridge chamber 10 through the air inlet 101 of the filter cartridge. Larger dust particles settle directly into the funnel 40 due to gravity. The remaining fine dust particles are purified through the deep surface of the filter cartridge 8. The clean air passes through the inside of the filter cartridge 8, the clean room where the venturi tube 9 is located, the air inlet hood 12 of the high-efficiency filter 7, the high-efficiency filter 7, and finally the purified air flows out of the dust collector.

[0045] When the dust on the surface of the filter cartridge 8 accumulates to a certain amount, and the pressure difference between the surface and the interior of the filter cartridge 8 reaches a preset value, the pulse controller 51 is triggered to control the air jet system, which instantly releases the compressed air in the compressed air tank 50 to backflush the filter cartridge 8, causing the dust on the surface of the filter cartridge 8 to fall into the funnel 40. Users only need to periodically operate the manual pressure relief valve to clean the dust in the funnel 40 and the ash storage bin 42.

[0046] In summary, this utility model adopts a mobile integrated structure design, making it flexible and convenient to install, with a small footprint and a reasonable dust collection airflow layout design. The two-stage purification of the filter cartridge 8 and the high-efficiency filter 7 meets the dust collection requirements. The bag-in-bag-out replacement method of the filter cartridge 8 and the high-efficiency filter 7 achieves a good sealing effect. The setting of the ash bucket hanging plate 43 facilitates the replacement of the dust collection bag 45 and enables online cleaning of the ash storage bucket 42. It effectively solves the problems of difficult dust isolation and collection in the pharmaceutical machinery industry, easy leakage when replacing the dust collection bag 45, and complex design of the high-efficiency filter sealing mechanism.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
