A suspension type air inlet filter cotton fixing structure and fixing method

Abstract

The invention discloses a suspension type air inlet filter cotton fixing structure and a fixing method. The fixing structure includes an air inlet plate, a grille plate, a first overturned pressing plate assembly, a second overturning pressing plate assembly, filter cotton and two stoppers , the grille plate is located at the lower part of the air inlet plate, the filter cotton is located between the grille plate and the air inlet plate, the upper end of each limiting member is fixedly connected to the air inlet plate, and the lower end passes through the grille plate, the first overturning platen assembly One end of the second turning platen assembly is rotatably connected to the lower end of the corresponding stopper, and the other ends of the first turning platen assembly and the second turning platen assembly are detachably connected to the lower surface of the air inlet plate. The invention adopts the specially designed overturning pressure plate assembly to cooperate with the air inlet plate and the grille plate, and the fixing, disassembly and replacement of the filter cotton can be quickly realized by rotating the overturning pressure plate assembly, without the need to disassemble the structural parts as a whole, which can effectively reduce the maintenance and replacement time .

Description

technical field [0001] The invention belongs to the technical field of gas filtration, and in particular relates to a suspension type air inlet filter cotton fixing structure and a fixing method. Background technique [0002] The rail transit industry currently uses a large number of filter mechanisms made of superimposed layers of stainless steel wire mesh. It is only aimed at special areas (such as Nanjing) where there are many rail vehicles. Cleaning the filter screen once brings cumbersome cleaning work and frequent vehicle scheduling. The most simple and reliable structure is multi-bolt fixing. This structure is simple and reliable, but it takes a long time to operate. Remove multiple bolts, replace the filter cotton, and then restore the installation, and do anti-loosening for the re-fixed bolts. Marking is complex and inefficient. Contents of the invention [0003] The object of the present invention is to provide a suspension type air inlet filter cotton fixing s...
