Abstract
The utility model discloses a mine dust protective cover for underground workers, which comprises a protective cover body (1). A vent-hole area (2) with a seal door (8) is arranged at the center of the protective cover body (1). Activated carbon is placed inside the vent-hole area (2). A guide tube (3) is connected to the vent-hole area (2), and the lower end of the guide tube (3) extends into an oxygen bottle (4). A valve switch is disposed on the guide tube (3). The activated carbon is disposed in the vent-hole area to absorb mine duct and protect the underground workers from mine dust invasion. In case of a danger, the vent-hole area can be closed to discharge carbon dioxide into the oxygen bottle, and oxygen can be sucked by a user from the oxygen bottle to maintain vitals while the user awaits rescue. In addition, owing to pores on the mine dust protective cover, hearing of the workers cannot be affected.
Description
Technical field
The utility model relates to a kind of protective cover, is specifically related to underground labour's mine dust protective cover of a kind of underground labour of being applicable to.
Background technology
Coal is as China's one big nonmetal energy, and its purposes can not be ignored.Yet in the manufacturing process of coal, All Jobs can both produce mine dust, and the dust burden that produces during wherein with mining work serves as at most, accounts for 80% of whole mine dusts; With regard to coal dust, having no under the dust prevention condition, general every generation round the clock approximates the 0.25%-1.0% of producing coal amount, even up to 3%.Its great majority all are that suspended state exists, and miner's health safety in serious harm.In all kinds of occupational diseases of China, the pneumoconiosis patient has reached 80%, causes tens huge loss every year.So be necessary to design the safety that a kind of protective cover is protected the miner.
The utility model content
The utility model discloses a kind of underground labour's mine dust protective cover, this protective cover can effectively prevent the suction of mine dust, when meeting with danger, oxygen can be provided simultaneously, earns a bare living.
For solving the problems of the technologies described above, the structure of the utility model comprises protecting cover, and the ventilative porose area in that the central authorities of protecting cover are provided with the band hermatic door is placed with active carbon in the ventilative porose area; Be connected with conduit on the ventilative porose area, the lower end of conduit is stretched in the oxygen cylinder; On conduit, be provided with valve switch.
There is the district of coating the both sides of described protecting cover, coat in the district and have the hole.
The utility model has been placed active carbon at ventilative porose area, and in order to the absorption mine dust, the protection underground labour avoids the infringement of mine dust.When causing danger, then can close ventilative porose area, carbon dioxide is entered oxygen cylinder, and from oxygen cylinder, draw oxygen, to earn a bare living, wait for rescue.And the utility model guarantees that through the hole is set workman's hearing is unaffected.
Description of drawings
Fig. 1 is the structural representation of the utility model when not connecting oxygen cylinder;
Structural representation when Fig. 2 is the utility model connection oxygen cylinder.
The specific embodiment
The embodiment of the utility model: like Fig. 1, shown in Figure 2, the structure of the utility model comprises protecting cover 1, and the ventilative porose area 2 in that the central authorities of protecting cover 1 are provided with band hermatic door 8 is placed with active carbon in the ventilative porose area 2; Be connected with conduit 3 on the ventilative porose area 2, the lower end of conduit 3 is stretched in the oxygen cylinder 4; On conduit 3, be provided with valve switch 6.The district of coating 7 is arranged in the both sides of protecting cover 1, unaffected in order to guarantee workman's hearing after wearing this protective cover, in coating district 7, have hole 9.
When wearing the protective cover of the utility model at ordinary times, hermatic door 8 is opened, and valve switch 6 is closed, and oxygen cylinder 4 can connect also and can not connect this moment.Institute's inhaled air filters through the charcoal absorption in the ventilative porose area 2, has guaranteed the cleaning of the air that sucks.When danger takes place, close hermatic door 8 (being arranged to the form of stretched), open valve switch 6, this moment, the lower end of conduit 3 will be inserted in the oxygen cylinder 4.Can be drawn to oxygen.
Depositing some in the oxygen cylinder 4 can get final product with the solid that carbon dioxide reaction generates oxygen, and such as like Fig. 1, potassium superoxide 5 shown in Figure 2, the molecular formula of potassium superoxide is KO
2, the chance reaction that carbon dioxide took place is:
4KO
2+2CO
2＝2K
2CO
3+3O
2↑
Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technician in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
