Problems solved by technology

[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, complex operation, low efficiency

Abstract

The invention discloses a suspension type air inlet filter cotton fixing structure and a fixing method. The fixing structure comprises an air inlet plate, a grating plate, a first overturning pressingplate assembly, a second overturning pressing plate assembly, filter cotton and two limiting pieces. The grating plate is positioned at the lower part of the air inlet plate; the filter cotton is positioned between the grating plate and the air inlet plate; the upper end of each limiting piece is fixedly connected to the air inlet plate, the lower end of each limiting piece penetrates out of thegrating plate, one end of the first overturning pressing plate assembly and one end of the second overturning pressing plate assembly are rotationally connected with the lower ends of the corresponding limiting pieces, and the other end of the first overturning pressing plate assembly and the other end of the second overturning pressing plate assembly are detachably connected to the lower surfaceof the air inlet plate. The overturning pressing plate assembly which is specially designed is adopted to be matched with the air inlet plate and the grating plate, so the filter cotton can be rapidlyfixed, disassembled, assembled and replaced by rotating the overturning pressing plate assembly, structural parts do not need to be integrally disassembled, and the maintenance and replacement time can be effectively shortened.

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...
