[0017] The present invention is further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0018] A novel explosion-proof bucket elevator comprises a head 1 and a tail 2, a plurality of standard barrel sections 3 and a connecting section 4 are arranged between the head 1 and the tail 2, a plurality of standard barrel sections 3 form a group, the connecting section 4 is located between two adjacent groups of standard barrel sections 3, the connecting section 4 can balance the airflow pressure difference of the pipe walls on both sides, enhance the structural strength of the pipe wall of the elevator, make the elevator run more smoothly, fill the bucket more fully, and increase the lifting capacity of the elevator, a reciprocating bucket belt 5 and a bucket 6 are arranged in the head 1, the tail 2, the standard barrel 3 and the connecting section 4, a dust collecting pipe 7 is respectively connected to the top of the tail 2 and the connecting section 4, the end of the dust collecting pipe 7 extends to the outside of the standard barrel 3 and is connected to a dust removal fan 8, and the dust in the tail 2 and the connecting section 4 is sucked out through the dust collecting pipe.

[0019] Furthermore, a dust filter 9 is provided between the dust removal fan 8 and the dust collecting pipe 7 , and the dust filter 9 filters the gas sucked out by the dust removal fan 8 .
