[0038] At the same time, after adjusting the position of the closed hemisphere 702, the handle 607 is pulled upward, and the pull rod 605 is held to move the pull rod 605 vertically along the inner wall of the handle 607, and the wedge block 603 is driven inward by the traction rope 604 to separate the wedge block 603 from the inner wall of the limiting plate 608, thereby achieving the purpose of quickly releasing the fixing effect of the cover body 602 and the drying cylinder 2, and the cover body 602 and the filter cylinder 8 are taken out upward along the top, so as to achieve the effect of quickly taking out and replacing the filter cylinder 8, thereby improving the maintenance efficiency.
