Variable air duct dust remover convenient to maintain

Abstract

The invention relates to a variable air duct dust remover convenient to maintain. The dust remover comprises an external air duct and a middle connecting air duct. The external air duct comprises an air inlet pipe, an exhaust pipe and a filter pipe set, the middle connecting air duct comprises a collecting pipe, and the filter pipe set is connected to the collecting pipe in an annular array mode;the filter pipe group comprises a filter pipe shell, an air inlet pipe is arranged at one axial end of the filter pipe shell, and a filter bag A is connected to the tail end of the air inlet pipe; anexhaust nozzle is connected to the inner wall of the other axial end of the filter shell, and an air valve A is connected to the necking end of the exhaust nozzle; the outer wall of the filter pipe shell is vertically connected with a connecting pipe used for being communicated with the collecting pipe, and a filter bag B is arranged at the end part of the connecting position of the connecting pipe and the filter pipe shell; an openable access cover is also arranged on the wall surface of the filter pipe shell; an auxiliary ventilation pipe is further connected between the front-end air inletpipe and the air inlet pipe of the shell of the second group of filter pipes in the array, and an air valve C is connected to the auxiliary ventilation pipe.

Description

technical field [0001] The invention relates to a variable air duct dust collector which is easy to maintain and belongs to the field of dust removal equipment. Background technique [0002] Dust removal equipment is a kind of filter equipment that needs to work for a long time. Traditional dust removal equipment generally adopts a fixed structure of multi-filter bag arrays. Each filter bag is placed in a filter cavity. , it needs to be shut down, and the filter bag will be disassembled after the shutdown, so production will be shut down during the filter bag replacement process, which will affect the benefits of the enterprise. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the technical problems in the prior art and provide a variable air duct dust collector which is easy to maintain. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] An easy-to-mai...
