Abstract
The utility model discloses an underground positive pressure dustproof breathing mask, which comprises a mask main body; one end of the mask main body is connected with the oil-water separator through an elastic device; one side of the oil-water separator is connected with an underground working surface pressure reducing valve; the pressure reducing valve of the underground working surface is arranged on a pipeline; the pipeline is provided with a filter; one side of the pipeline is connected with an air storage tank for supplying air; one side of the gas storage tank is connected with an air compressor. Beneficial effect is that the utility model relates to a repeated many times's dust mask filters the air that gets into through setting up devices such as oil water separator, filter, prevents that the dust from getting into, simultaneously, utilizes the air compressor machine to carry out the circulation motion to the air, and the supply amount of wind greatly increases and ensures that personnel remain the face guard inside throughout at the in-process of breathing and be the malleation, and outside air and dust can not get into in the face guard.
Description
Technical Field
The utility model relates to a dustproof respirator of malleation in pit belongs to the labor protection field.
Background
Dust generated in the construction processes of underground rock drilling, slurry spraying, tunneling of a fully mechanized excavating machine and the like of a mine greatly damages the body of workers. At present, the main protective article used by operators is a dust mask. The dust mask is mostly a disposable article, and the dust-proof effect is not good under the condition that the dust is big.
SUMMERY OF THE UTILITY MODEL
Problem to above-mentioned prior art exists, the utility model provides a malleation respirator that prevents dust in pit for solve the dust mask in the past and prevent the unsatisfactory problem of dust effect when great dust situation.
In order to realize the purpose, the utility model discloses a technical scheme is: a downhole positive pressure dustproof breathing mask comprises a mask body; one end of the mask main body is connected with the oil-water separator through a spring hose; one side of the oil-water separator is connected with an underground working surface pressure reducing valve; the pressure reducing valve of the underground working surface is arranged on a pipeline; the pipeline is provided with a filter; one side of the pipeline is connected with an air storage tank for supplying air; one side of the gas storage tank is connected with an air compressor.
Furthermore, the spring hoses are connected with the mask main body.
The utility model has the advantages that: the utility model discloses an utilize dustproof respirator of malleation in pit of air compressor machine air feed, it is dustproof effectual, and can practice thrift the cost. Each underground working face is provided with a compressed air pipeline air supply system, so that air supply is convenient, and the air quantity can be ensured to meet the requirements. The air that gets into is filtered through setting up devices such as oil water separator, filter, prevents that the dust from getting into, simultaneously, utilizes the air compressor machine to carry out the circulation motion to the air, and the air feed volume is big to be increased and ensures that personnel remain the inside malleation that is of face guard all the time at the in-process of breathing, and outside air and dust can not get into in the face guard.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: 1. the mask comprises a mask body, 2 parts of a spring hose, 3 parts of an oil-water separator, 4 parts of a pressure reducing valve of an underground working surface, 5 parts of a filter, 6 parts of an air storage tank, 7 parts of an air compressor.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail through the accompanying drawings and embodiments. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
As shown in fig. 1, the underground positive pressure dustproof breathing mask comprises a mask body 1; one end of the mask main body 1 is connected with an oil-water separator 3 through a spring hose 2; one side of the oil-water separator 3 is connected with a downhole working surface pressure reducing valve 4; the pressure reducing valve 4 of the underground working face is arranged on a pipeline; the pipeline is provided with a filter 5; one side of the pipeline is connected with an air storage tank 6 for air supply; one side of the air storage tank 6 is connected with an air compressor 7.
The number of the spring hoses is multiple, and the spring hoses 2 are connected with the mask main body 1.
The utility model discloses mainly be 7 amount of wind of air compressor machine arrive the working face in the pit after through the air feed pipeline, connect working face relief pressure valve 4, oil water separator 3 in the pit in proper order at the pipeline end, pass through many spring hose 2 of tube coupling through filterable air and provide fresh air for the 1 inside cavity of a plurality of face masks main part. The mask body 1 has a connector that can be connected directly to the spring hose 2. The air supply quantity of the air compressor 7 at the tail end of the spring hose 2 is 2-3 times of the breathing oxygen demand, and the filter 5 and the oil-water separator 3 ensure that the inside of the mask is always kept at positive pressure in the breathing process of people, and external air and dust cannot enter the mask main body 1.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
