Fig. 1-4 show a specific embodiment of the present invention, which is a mining heading face self-blowing respirator device, and the embodiment is composed of a box body 10, a gas circuit control system, an air filter 6 and a breathing mask 9.

The embodiment is applied to the position of a mine heading face, and the box body 10 is mainly used for installing various equipment parts and placing the breathing mask 9 to prevent dust and coal slag from entering; the gas path control system controls gas supply of a gas source, the gas enters the oil-water separator 5 firstly, most of oil mist and water vapor in the gas supply can be filtered out, and then the gas passes through the air filter 6. The internal structure of the air filter 6 is divided into two layers, wherein one layer is an active carbon adsorption layer and can adsorb various toxic and harmful gases in the air; one layer is an imported air filtering cotton layer and has the characteristics of high air permeability, low pressure loss, high dust accumulation, hygroscopicity, acid and alkali filtering, pressure resistance, long service life and the like. After the two layers of filtering, the air becomes clean, which is beneficial to the health of the respiratory system. And finally, the dust-proof breathing mask is connected to the dust-proof breathing mask through a pipeline. The structure of the breathing mask adopts a totally-enclosed structure, the part above the neck is completely covered, and the dust and other particles on the tunneling surface are prevented from being attached to the face.

This implement the whole device outside and adopted the stainless steel as the shell, can effectively block the entering of filths such as cinder dust in the environment, guaranteed the inside clean and tidy of equipment. Meanwhile, the box body is provided with the door lock, so that the door lock can be locked when the equipment is not used, and the integral integrity of the equipment is ensured.

In the gas circuit control system of this embodiment, pneumatic valve 3 can control user's air feed, is in the closed condition under the state of not using, can effectually save the inside conveying gas of mine, saves the resource. The gas in this embodiment has firstly passed through oil water separator 5, gets rid of most oil mist and aqueous vapor in the air supply of air supply, impurity and filth in can the effectual reduction air, can adjust the pressure of air feed simultaneously. It is important to adjust the amount of intake air by the pipe throttle 4, and the adjustment of the amount of intake air is particularly important because a negative pressure state may occur during the working of the excavation face under the mine.

The specific work flow of this embodiment is as follows:

when a worker is in a heading face in a mine to carry out related work, the breathing mask 9 can be taken out of the box body 10 of the respirator and taken to the head, then the pneumatic valve 3 in the box body is opened, and meanwhile, the gas flow can be adjusted according to the requirement, so that the breathing mask 9 carried by the worker can work in the mine comfortably. When the respirator is not used, the respirator 9 can be taken down, the pneumatic valve 3 is closed, and the respirator is put into the box and locked.

Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
