Abstract
The invention discloses a positive pressure respiratory system, comprising a filtering device, a water tank, an air supply valve and a face mask, which are connected through pipelines in sequence. The positive pressure respiratory system is simple in structure and convenient to use, and enables a user to breath more comfortably; and besides, outside harmful gas is prevented from entering the respiratory organ of the user, and the application safety factor is high.
Description
Technical field
The present invention relates to a kind of anti-dust respiratory system, particularly a kind of positive pressure respiration system.
Background technology
At present, development machine when work, especially during stone drifting, can produce a large amount of dust, harm operator's respiratory function, serious in addition can influence the driving personnel healthy, therefore need have the respiratory system of face shield.In the prior art, the supply gas pressure of traditional respiratory system is not very stable, always needs continuous adjusting, and not only operating efficiency is low, also may influence health of operators; On the other hand, traditional respiratory system is not malleation, enters face shield thereby can not stop hazardous substances such as dust, thereby is damaged in operating personnel's suction body.
Summary of the invention
The purpose of this invention is to provide a kind of positive pressure respiration system, simple in structure, easy to use, the wearer breathes and feels happier; And, can intercept the respiratory apparatus that extraneous pernicious gas is invaded the wearer, use the safety coefficient height.
In order to realize above purpose, the present invention is achieved by the following technical solutions:
A kind of positive pressure respiration system comprises: link to each other by pipeline successively: filter, water tank, steam supply valve and face shield.
Described filter comprises first order filter, second level filter, the third level filter that connects successively; Described first order filter links to each other with outside atmosphere by pipeline; Described third level filter links to each other with water tank by pipeline.
Described third level filter is charcoal filter.
Described face shield is the demifacet cover.
The gas pressure scope that described steam supply valve is exported to face shield is 3 ~ 10bar.
The present invention compared with prior art has the following advantages:
1, simple in structure, easy to use, the wearer breathes and feels happier;
2, can intercept the respiratory apparatus that extraneous pernicious gas is invaded the wearer, use the safety coefficient height.
Description of drawings
Fig. 1 is the structural representation of a kind of positive pressure respiration of the present invention system.
The specific embodiment
Below in conjunction with accompanying drawing, by describing a preferable specific embodiment in detail, the present invention is further elaborated.
As shown in Figure 1, a kind of positive pressure respiration system comprises: link to each other by pipeline 1 successively: filter 2, water tank 3, steam supply valve 4 and face shield 5.
As shown in Figure 1, in the present embodiment, filter 2 is selected tertiary filter for use, and wherein, this tertiary filter comprises first order filter 21, second level filter 22, the third level filter 23 that connects successively; First order filter 21 links to each other with outside atmosphere by pipeline 1; Third level filter 23 links to each other with water tank 3 by pipeline 1.Wherein, first order filter 21 is the coagulation type accurate filter, and second level filter 22 is coagulation type ultraprecise filter, and this two-stage filter is used for liquid profit, the solid contaminant that filtering compressed air contains; Third level filter 23 is charcoal filter, is used for residual gaseous state oil and the peculiar smell of absorption compressed air, ensures compressed-air actuated cleaning.Greasy dirt in the compressed air after tertiary filter filters is residual≤0.003mg/m
3Thereby, make clean air after the filtration satisfy the requirement of breathe air standard.In the present embodiment, the particle size that first order filter 21 can filtering is 1 micron, handles back compressed air oil content＜0.1mg/m
3 Second level filter 22 can filtering particle size be 0.01 micron, handle back compressed air oil content＜0.01mg/m
3
In the present embodiment, face shield 5 is the demifacet cover, and the gas that this Open architecture makes the user of service breathe out directly can directly enter atmospheric environment, makes to breathe to feel happier.
Owing to adopted steam supply valve 4, adjustable gas pressure, in the present embodiment, steam supply valve 4 is selected VERG-10 type balanced type steam supply valve for use, thereby, the gas pressure scope of steam supply valve 4 outputs that face shield 5 receives is 3 ~ 10bar, comes atmospheric pressure need not reduce pressure in 3 ~ 10bar scope, has avoided the frequent adjusting that causes because of the supply gas pressure shakiness, this air pressure is also all the time greater than the atmospheric pressure in the external world, thereby the formation malleation makes extraneous pernicious gas can't invade wearer's respiratory apparatus, uses the safety coefficient height; And throughput is big and stable, feels happier when the user of service breathes.
When using, by pipeline 1 compressed air is sucked, after filter 2 filtrations, the compressed air of cleaning is passed through water tank 3 humidifications, to guarantee air humidity, clean air behind the humidification is given face shield 5 air feed through steam supply valve 4, thereby has both ensured user of service's eupnea gas, has also guaranteed user of service's health.
In sum, a kind of positive pressure respiration of the present invention system, simple in structure, easy to use, the wearer breathes and feels happier; And, can intercept the respiratory apparatus that extraneous pernicious gas is invaded the wearer, use the safety coefficient height.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
