Ventilation equipment for subway construction

Abstract

The invention relates to the field of ventilation in construction, and discloses ventilation equipment for subway construction in order to solve the problem that existing ventilation equipment for construction does not have an automatic cleaning function for a filter screen during use. The ventilation equipment for subway construction comprises a box body; a first air suction part is installed on the outer wall of one side of the box body; an air inlet part is installed on the other side of the box body; and a partition plate is installed on the inner wall of the box body. When the equipment is used, an air guide cover guides air to enable airflow to be blown to side wings, and the air guide cover is of a Venturi tube structure, so that it is guaranteed that the speed of the airflow blown to the side wings is high, and the side wings and a rotating part are blown to rotate; and meanwhile, an air suction mechanism sucks air at the construction position into the box body, a third filtering part filters the air entering the box body, the rotating part drives a dust removal part to rotate to clean the third filtering part, and part of the airflow enters the rotating part through an air inlet and is sprayed out through an air outlet while the airflow is blown to the side wings, so that the cleaning effect on the third filtering part is improved.

Description

technical field [0001] The invention relates to the technical field of construction ventilation, in particular to a subway construction ventilation equipment. Background technique [0002] The subway is a fast, large-capacity, electric traction rail transit built in the city. The train runs on a fully enclosed line. The lines located in the central urban area are basically located in underground tunnels, and the lines outside the central urban area are generally located in viaducts. Or on the ground, where a large amount of dust and harmful gas will be generated inside the tunnel during the construction of the subway in the underground tunnel. [0003] In order to ensure the health of construction workers, it is necessary to ensure effective ventilation in the tunnel. The existing subway construction ventilation equipment does not have the function of automatically cleaning the filter screen during use. Contents of the invention [0004] The purpose of the present inventi...
