Abstract
The utility model relates to a mine fire door which comprises a door body, a door hinge and a latch. The mine fire door is characterized in that the door body consists of a door frame, a mesh door panel, a fixing bracket and a fire isolation layer; the mesh door panel is made from metal material or composite material; the mesh density of the mesh door panel is 210-250 holes per square centimeters; packing used for absorbing harmful gases is filled into the fire isolation layer; and the fixing bracket is used for fixing the mesh door panel and enables the packing to be uniformly filled. When the flame area in tunnels reaches the mine fire door, the small holes formed by the mesh door panel and the fire isolation layer can prevent the flame from spreading, and the packing in the fire isolation layer can absorb the harmful and poisonous gases in the air. As the mesh door panel and the fire isolation layer of the mine fire door can ventilate, the mine fire door maintains the circulation of the air flow, avoids forming a closed space, reduces the accumulation of the combustible gas, and avoids generating the explosion in the closed space. The mine fire door can prevent the flame from spreading, absorb a certain amount of poisonous and harmful gases, and reduce the possibility of injury or death of personnel and explosion.
Description
Technical field
The utility model relates to a kind of mining fire protection equipment, a kind of mining fire-separated door of more specifically saying so.
Background technology
Along with increasing of middle and small scale coal mine, the coal-mine fire accident happens occasionally, and the safety problem in colliery has more and more caused people's attention.At present, during the down-hole breaking out of fire, it is commonly used that to avoid fire spread and gas explosion measure be to pile up fire dam, this kind method is in construction and demolishing process, the preparation amount is big, high material consumption, enforcement required time are long, and can form confined space in the process of piling up, and causes the hazardous gas gathering and then causes more serious blast, therefore these methods can not satisfy the needs of controlling the condition of a disaster quickly and effectively, can not provide rescue and relief for disasters and emergencies for mine and race against time.
Summary of the invention
The purpose of this utility model provides a kind of mining fire-separated door, and not only fire prevention, heat insulation can also reach the effect of avoiding the confined space blast and absorbing certain toxic and harmful.
The purpose of this utility model can realize in the following manner: a kind of mining fire-separated door, constitute by door body, door-hinge, bolt, and its characteristics are: the door body is made of doorframe, wire side door-plate, fixed mount, refuge floor; The wire side door-plate is that metal material or composite material are made, and its mesh density is every square centimeter 210～250 hole; The chemicals that refuge floor is filled some graininess fine sand grains, little bead, iron filings and is used to absorb pernicious gas, the filler particle diameter of refuge floor are all greater than the mesh aperture of wire side door-plate; Fixed mount is used for fixing the wire side door-plate, fills well-balanced to guarantee the filler in the refuge floor.
In each tunnel of mine this mining fire-separated door is installed all, when mine is produced, mining fire-separated door is opened, do not influence normal ventilation requirement; When taking place, fire closes mining fire-separated door rapidly, when the flame front in the tunnel arrives mining fire-separated door, utilize gap flame arrest principle, many nonlinearities fine pore that wire side door-plate and refuge floor form will stop spreading of flame, and the chemicals in the refuge floor can absorb toxic and harmfuls a large amount of in the air simultaneously.In addition,, kept the circulation of air-flow, avoided the formation of confined space, reduced the fuel gas gathering, and then avoided the generation of confined space implode because the wire side door-plate and the refuge floor of this mining fire-separated door are ventilated.
The utility model compared with prior art has following advantage: under the prerequisite that effectively prevents flame propagation, can absorb the toxic and harmful that a certain amount of scene of fire produces, reduce casualties and atmosphere pollution, the particles filled thing of wire side door-plate and refuge floor has the space simultaneously, kept certain circulation of air, avoid confined space, reduced the possibility of blast.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 3 is the local enlarged diagrams of wire side door-plate.
Among the figure: 1-door body, 2-door-hinge, 3-bolt, 4-doorframe, 5-wire side door-plate, 6-fixed mount, 7-refuge floor.
The specific embodiment
As follows with reference to accompanying drawing: a kind of mining fire-separated door of the utility model, constitute by door body 1, door-hinge 2, bolt 3, its characteristics are: door body 1 is made of doorframe 4, wire side door-plate 5, fixed mount 6, refuge floor 7; Wire side door-plate 5 is made for metal material or composite material, and the mesh density of wire side door-plate 5 is every square centimeter 210～250 hole; The chemicals that refuge floor 7 is filled some granular fine sand grains, little bead, iron filings and is used to absorb pernicious gas, the filler particle diameter of refuge floor 7 is all greater than the mesh aperture of wire side door-plate 5, fixed mount 6 is used for fixing wire side door-plate 5, fills well-balanced to guarantee the filler in the refuge floor 7.
In each tunnel of mine this mining fire-separated door is installed all, when mine is produced, mining fire-separated door is opened, do not influence normal ventilation requirement; When taking place, fire closes mining fire-separated door rapidly, when the flame front in the tunnel arrives mining fire-separated door, utilize gap flame arrest principle, many nonlinearities fine pore that wire side door-plate 5 and refuge floor 7 form will stop spreading of flame, and the chemicals in the refuge floor 7 can absorb toxic and harmfuls a large amount of in the air simultaneously.In addition,, kept the circulation of air-flow, avoided the formation of confined space, reduced the fuel gas gathering, and then avoided the generation of confined space implode because the wire side door-plate 5 and the refuge floor 7 of this mining fire insulation curtain door are ventilated.
