[0030] Working principle: Before using this pulse bag dust collector with dust removal components, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6As shown, by sliding the top plate 104 inside the shell 101, the top plate 104 is located at the outside of the support rod 103 and slides. When the bag tube 105 is installed, the staff pulls the two sets of extrusion frames 202 with both hands. At this time, the extrusion frames 202 drive the movement of the movable plate 204, thereby causing the first contraction spring 203 to contract.
