The invention discloses a shaft dust removal device of an anti-explosion elevator. The shaft dust removal device comprises a dust removal box, a dust suction unit and a dust blocking unit. A middle concave plate is mounted at the upper end in the dust removal box; the dust collection unit comprises dust stopping inclined plates, a non-return seat, a non-return arc plate, a torsional spring and a dust collection fan, the dust stopping inclined plates are installed on the left side and the right side in the dust collection box, the non-return seat is installed at the lower end of each dust stopping inclined plate, a non-return shaft is rotationally connected to the middle of each non-return seat, the lower end of each non-return arc plate is connected with the corresponding non-return shaft, and the torsional spring is connected to the middle of the corresponding non-return shaft in a sleeving mode. One end of the torsion spring is connected with the non-return seat, the other end of the torsion spring is connected with the non-return arc plate, and four corners of the four dust collection fans are in threaded connection with the upper sides of the inclined plates at the left end and the right end of the dust removal box through fan fixing bolts respectively. According to the elevator shaft, external dust can be prevented from entering the shaft, the dust entering the shaft can be extracted, the environment in the shaft is guaranteed, and the using effect is better.
