At this time, 70% of the powder is intercepted on the surface of the filter element by the detachable pleated filter element 4, wherein the filtration accuracy of the pleated filter element 4 is 5 microns, and then the powder gas with a small amount of fine powder enters the pulse dust collector 5, which is equipped with a coated filter bag 12 with a filtration accuracy of 1 micron, to remove the fine powder, and then back-blow the filter bag to clear it, and the powder falls into the receiving hopper 11 and accumulates;
