Special fiber dust filtration series air suction equipment

The utility model relates to the field of air suction filtering equipment, in particular to special fiber dust filtration series air suction equipment which comprises a bottom plate, side plates are arranged at the two ends of the upper surface of the bottom plate, an upper cover plate is arranged at the upper ends of the two side plates, supporting columns are arranged on the outer surfaces of the two side plates, and lifting mechanisms are arranged between the two supporting columns. And a fan mechanism is arranged at the rear end of the lifting mechanism. By adopting the lifting mechanism, the filter cloth can be easily taken out for replacement operation, so that the normal operation of dust filtration work is facilitated. The filter cloth clamping mechanism adopts a fixing bolt to cooperate with a clamping block to press downwards, so that the filter cloth is fixed between the clamping block and a clamping plate. The sealing cover arranged on the upper cover plate can be flexibly lifted and rotated along
