Problems solved by technology

[0003] In the prior art, the existing air-supply devices for civil air defense projects are simple in structure, only have a simple air-supply function, and do not have the ability to filter air. Because the external air will be mixed with some ammunition and shell dust during wartime, once these mixed air If it is absorbed by the human body for a long time, it will cause great damage to human health. Now there is an urgent need for an air supply filter device for civil air defense engineering to solve the above problems

Abstract

The invention provides an air supplying and filtering device for civil air defense engineering. The device comprises an interwoven fabric filter plate, a multilayer sintered metal filter plate, an alloy protective screen plate, a main supporting roller, a driving baffle, sealing rubber sheets and a connecting rod, wherein the sintered metal plate is clamped on the right side of the interwoven fabric filter plate; the alloy protective screen plate is mounted on the right end surface of a filtering shell. By means of the design, the problem that an original air supply structure for civil air defense engineering does not have filtering and purifying capacity is solved. The main supporting roller is installed on the upper side of the inner wall of an adjusting shell the driving baffle is clamped on the annular side surface of the main supporting roller, the connecting rod is inserted into the rear side in the driving baffle and the sealing rubber sheets are symmetrically clamped on the front and rear ends of the driving baffle, and therefore the problems that an original air supply structure for civil air defense engineering is inconvenient in air volume adjustment, complex in structure and easy to damage can be solved. Compared with the prior art, the air supplying and filtering device is reasonable in structure, facilitates air filtration and purification, facilitates air supplyvolume adjustment and is convenient to install and fix.

Description

technical field [0001] The invention is an air supply filter device for civil air defense engineering, which belongs to the technical field of civil air defense engineering. Background technique [0002] Civil air defense projects, also known as civil air defense fortifications, refer to underground protective buildings built separately to protect personnel and material shelter, civil air defense command, and medical rescue in wartime, as well as basements that can be used for air defense in wartime built in combination with ground buildings. The civil air defense project is an important facility to prevent sudden enemy attacks, effectively cover personnel and materials, and preserve war potential; it is an engineering guarantee to persist in urban combat and long-term support for anti-aggression wars until victory. [0003] In the prior art, the existing air-supply devices for civil air defense projects are simple in structure, only have a simple air-supply function, and do...
