Abstract

Disclosed is an explosion-proof fan with a detachable connecting portion, the explosion-proof fan comprising a main air drum (10), wherein the middle of the main air drum (10) is provided with an explosion-proof electric motor (11); an impeller (12) is fixed on an output shaft of the explosion-proof electric motor (11); an inner connecting plate (13) abuts against an inner side wall of a wall plate of both the left side and the right side of the main air drum (10), and an outer connecting plate (14) abuts against an outer side wall of the wall plate of both the left side and the right side of the main air drum (10); and the inner connecting plates (13) and the wall plates of the main air drum (10) are connected and fixed to the corresponding outer connecting plates (14) by means of fixing bolts (15). Connecting elongated plates (141) and extending connecting frames (20) are mounted at the side walls of the main air drum (10) for connection on the vertical wall faces, so as to achieve convenient connection. Moreover, bottom installation can be achieved by means of a bottom connecting base (19) as required, such that the installation modes thereof are varied, thus meeting different installation requirements.

Description

technical field [0001] The invention relates to the technical field of fan processing equipment, and more particularly to an explosion-proof fan with a detachable connection part. Background technique [0002] Existing axial flow fans generally use outriggers welded at the bottom of the main cylinder, and the outriggers are welded on the brackets or fixed to the brackets by bolts. The installation method is simple and can only be fixed by the bottom of the outriggers. The axial flow fan cannot be fixedly installed on the vertical wall of the bracket, and cannot meet the installation requirements of some specific environments. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide an explosion-proof fan with a detachable connection part, which is connected to the vertical wall surface by installing and connecting the long plate and the extension connecting frame on the side wall of the main air du...
