Air curtain isolating device

Abstract

The invention discloses an air curtain isolating device, and belongs to the technical field of air curtain devices. The air curtain isolating device is installed on one side of a door frame, and the door frame comprises two stand columns which are arranged oppositely and a cross beam which is erected at the top ends of the stand columns; the air curtain isolating device comprises a mechanical valve which is installed on one of the stand columns and fixed on the face, opposite to the other stand column, of the stand column, the middle of the cross beam is provided with a tee joint, two transverse connectors of the tee joint are each connected with one end of an air curtain short pipe which is horizontally arranged, the other end of each air curtain short pipe is connected with the top end of an air curtain long pipe, each air curtain long pipe is vertically installed on one stand column, and the bottom ends of the air curtain long pipe are closed; a longitudinal connector of the tee joint is connected with one end of a straight pipe, the other end of the straight pipe is communicated with an air outlet of the mechanical valve through a metal hose, and an air inlet of the mechanical valve is connected with an externally air supply device through a metal hose. According to the air curtain isolating device, harmful components can be prevented from entering an office area along with opening of an isolation door.

Description

technical field [0001] The invention relates to the technical field of air curtain devices, in particular to an air curtain isolation device. Background technique [0002] In chemical laboratories, rescue chambers, and toxic gas test chambers, it is necessary to isolate harmful components (hazardous gases and dust, etc.) outside the office area to ensure the safety of staff in the office area.
