Detailed Description

The present invention will be further explained with reference to the accompanying drawings, as shown in fig. 1, a bag-type dust collector comprises a box 1, a middle box 2 and an ash bucket 3, wherein a filter bag 5, a flue gas inlet 7 and a flue gas outlet 8 are arranged in the middle box 2, a vertical fiber filter plate 64 is arranged near the flue gas inlet 7, a filter plate 4 is arranged at the junction of the middle box 2 and the ash bucket 3, the filter plate 4 is horizontally arranged, the fiber filter plate 64 is vertically arranged on the filter plate 4, wherein a gap is left between the fiber filter plate 64 and the wall of the middle box 2 and between the filter plate 4 and the flue gas inlet 7, the filter plate 64 filters the flue gas, a part of the filtered fiber falls into the ash bucket 3 from a blanking channel 12, wherein a lifting device is arranged on the fiber filter plate 64, and can take out the fiber filter plate 64 from the box, is convenient to clean.

Further, as shown in the top view of fig. 2, the side edges of both sides of the fiber filtering plate 64 are respectively provided with a clamping block 16 and a rack 19, a clamping groove is arranged inside the dust collector, the clamping groove is as long as the fiber filtering plate 64, the clamping block 16 is clamped in the clamping groove for fixing, a gear 18 is arranged at the position, close to the wall top, of the upper box body 1, and the gear 18 is meshed with the rack 19, so that the rack 19 is taken out.
