Problems solved by technology

The mask with filter cotton layer has been used for a long time, which will cause dust to block the filter cotton layer and cause poor air supply, and can not remove harmful poisonous gas. The mask with special filter and adsorption material has a good effect, but after a period of time (some (even only a few tens of minutes), it is necessary to replace the special filter adsorption material, which is very uneconomical for long-term application

Embodiment Construction

[0010] Every working environment with dust and poisonous gas has a certain space range, and the air inlets at both ends of the air supply main pipe (1) of this system device that isolates dust and poisonous gas (only one end can also be used as required, The other end is closed) placed in an air-clean and safe place outside the environmental range with dust and poisonous gas. The diameter of the air supply main pipe (1) depends on the number of users. Set the manual air distribution on the main pipe (1) The switch valve (2) is connected with the branch pipe (3), and the branch pipe (3) is connected with the mask (7) with a soft leather tube (4), which can move within a certain range. Pneumatic switching valve (6), its effect is that suction is opened, and exhalation is closed. The exhaust pipe (9) of mask (7) is also equipped with one-way pneumatic switching valve, and its effect is to open when exhaling and let the exhaled gas flow out, close when inhaling, do not allow dust ...

Abstract

The present invention relates to a dust and poisonous gas isolating device for person in dusty and poisonous environment to inhale clean air. The device includes air pipeline comprising main pipe, manual valve, branches and monoway pneumatic valve; and mask with monoway pneumatic valve and exhaust pipe. The main pipe has inlet extending to outside the dusty and poisonous environment for take clean air and the exhausted air from inside the mask is exhausted in the site. The monoway pneumatic valves in the air inlet pipe and the air exhaust pipe ensures the air intake from the air pipeline and air exhaust via the exhaust pipe.

Description

technical field [0001] The invention is a system device for separating dust and poisonous gas for people who work for a long time in an environment with dust or poisonous gas to inhale harmless air. Background technique [0002] At present, the dust and anti-virus protection of personnel who work for a long time in an environment with dust or toxic gas is to wear a mask with a filter cotton layer or a special filter and adsorption material. The mask with filter cotton layer has been used for a long time, which will cause dust to block the filter cotton layer and cause poor air supply, and can not remove harmful poisonous gas. The mask with special filter and adsorption material has a good effect, but after a period of time (some Even only in tens of minutes), it is necessary to replace the special filter adsorption material, which is very uneconomical for long-term application. Contents of the invention [0003] The purpose of the present invention is to provide a system ...
