Negative pressure filtering device for shelter hospital

Abstract

The invention discloses a shelter hospital negative pressure filtering device which comprises an air inlet assembly, a control assembly and an exhaust assembly, a fixing rod is arranged in a wall body, one side of the bottom end of the fixing rod is fixedly connected with a first support, and one side of the middle section of the wall body is fixedly connected with a second support. By arranging the air inlet assembly, air is filtered during air inlet so as to remove salt mist and impurity particles in the air, and impurities are collected in a scraping mode so as to guarantee the continuous filtering effect of the device; by arranging the control assembly, the negative pressure value in the square cabin can be freely adjusted to meet the use requirements of the device in different scenes, and then the application degree of the device is improved; the exhaust assembly is arranged and matched with the air inlet assembly to control the negative pressure environment of the shelter, meanwhile, exhausted air is disinfected, and the risk of pathogen diffusion is further reduced.
