Abstract
The utility model discloses a pneumatic supercharging positive-pressure respirator. The pneumatic supercharging positive-pressure respirator is characterized by comprising a skeleton air drum (1), a pneumatic supercharging device (2), a filtering device (3), an air flow guide pipe (4), an air flow branch pipe (5) and a mask (6) which are connected in sequence, wherein the skeleton air drum (1) is connected on an underground main air drum (7) so as to introduce fresh air flow; and at least one group of air flow branch pipe (5) and mask (6) are arranged. The pneumatic supercharging positive-pressure respirator disclosed by the utility model has the advantages that the fresh air flow of the underground air drum is directly utilized, the problem of an air flow supplying source is solved, the simple and convenient effects are achieved, the cost of the equipment is low and the popularization is easy; and by the supercharged and filtered air, the use of workers on site can be ensured and the injury of the high-dust environment to the workers can be avoided.
Description
Technical field
The utility model relates to a kind of pneumatic supercharging positive pressure respirator, and being mainly used in provides fresh breathing distinguished and admirable respirator for the staff in the high dust working environment.
Background technology
The colliery downhole powder dust refers to the fine coal dust that produces and the general name of rock dirt in coal production.The colliery downhole powder dust has following characteristic: dust adsorption one deck air film, hinder between dust or the flocking settling between water droplet and dust; The decentralization of dust increases, and is adsorbed on its surperficial oxygen molecule and increases, and has accelerated the dust oxidation decomposition course; Trickle rock dirt is because surface area increases, and the free silicon dioxide in the rock dirt dissolves readily in the Human Lung cell; The fresh dust that getting working face produces is easily charged than the dust in the air-return duct.Because dust has these characteristics and has determined following harm: easily cause pneumoconiosis; Easily cause burning and blast; High concentrate dust can wear and tear by acceleration mechanical, shortens the service life of precision instrument; In down-hole coal excavation, driving, reprinting, the transportation, produce a large amount of dust, the severe contamination subsurface environment.
Must administer because downhole powder dust pollutes, existing improvement method mainly is: the treating flour dust that carries out for the operation place of this colliery dust-producing amount maximum of coal-face; Mainly contain radially mist screen depositing dust of coal-winning machine; Coal-winning machine high pressure external spraying depositing dust; The improvement of disintegrating machine transfer point dust; The methods such as improvement of milling coal hole dust.Single protection tool for the coal mining personnel then mainly is mouth mask and mask; because the Dust Capacity concentration short time can't disappear; therefore; mouth mask and mask all can not really be protected coal mining personnel's breathing safety; the mining face under mine operating personnel need to a kind ofly can provide fresh distinguished and admirable breathing instrument with isolating dust, but have no report in the prior art.
Summary of the invention
In order to solve the problems of the prior art, the purpose of this utility model provides and a kind ofly can provide fresh distinguished and admirable pneumatic supercharging positive pressure respirator under high dust atmosphere.
For achieving the above object, the technological means of employing described in the utility model is: a kind of pneumatic supercharging positive pressure respirator, comprise the skeleton air duct, pneumatic supercharging device, filter, distinguished and admirable conduit, distinguished and admirable arm, the face shield that connect successively, wherein the skeleton air duct is connected on the main wind tube of down-hole, imports fresh distinguished and admirable; Described distinguished and admirable arm and face shield arrange one group at least.
Operation principle: main wind tube is fresh distinguished and admirable for what come; import pneumatic supercharging device by the skeleton air duct; after carrying out further supercharging; after device filters after filtration; by the face shield that is connected to distinguished and admirable supravasal distinguished and admirable arm supply individual and wears; breathe for staff in the high dust atmosphere, realize the isolation of people and dust, the Protection personnel's is healthy.
The beneficial effects of the utility model are: this respirator directly utilizes the fresh distinguished and admirable of down-hole air duct, has solved distinguished and admirable source of supply problem, and simple and convenient, equipment manufacturing cost is low, is easy to promote; Air through after supercharging and the filtration can guarantee field personnel's use, has avoided high dust atmosphere to staff's injury.
Description of drawings
Below in conjunction with accompanying drawing the technical solution of the utility model is described.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, skeleton air duct, 2, pneumatic supercharging device, 3, filter, 4, distinguished and admirable conduit, 5, distinguished and admirable arm, 6, face shield, 7, main wind tube.
The specific embodiment
A kind of pneumatic supercharging positive pressure respirator as shown in Figure 1, comprise the skeleton air duct 1, pneumatic supercharging device 2, filter 3, distinguished and admirable conduit 4, distinguished and admirable arm 5, the face shield 6 that connect successively, wherein skeleton air duct 1 is connected on the down-hole main wind tube 7, imports fresh distinguished and admirable; Described distinguished and admirable arm 5 and face shield 6 arrange one group at least.
Use the scene, the quantity of distinguished and admirable arm 5 and face shield 6 can be installed arbitrarily according to field condition, guaranteeing distinguished and admirable pressure by pneumatic supercharging device 2.
Skeleton air duct 1 supplies the pneumatic supercharging device 2 of fresh distinguished and admirable importing of coming with main wind tube 7; after carrying out further supercharging; installing after filtration 3 filters; filtering material uses absorbent charcoal material to satisfy the demand; the face shield 6 that the distinguished and admirable distinguished and admirable arm 5 supply individuals by being connected on the distinguished and admirable conduit 4 of air after the filtration wear; breathe for staff in the high dust atmosphere, realize the isolation of people and dust, the Protection personnel's is healthy.
