Fireproof door for preventing and controlling mine fire

Abstract

The invention discloses a fireproof door for preventing and controlling a mine fire. The fireproof door comprises a door body and a manhole penetrating through the door body, wherein two sliding doorsare arranged in the door body, and the sliding doors are parallel to the door body and are slidably connected to the bottom of the manhole; the tops of the two sides of the door body are jointly connected to an air flow adjusting device and a pressure relief device; the two sliding doors are respectively arranged on the two sides of the door body, each sliding door communicates with a flow adjusting chamber on the same side of the door body and hermetically communicates with an airflow channel, and the joint of each airflow channel and the corresponding flow adjusting chamber is located in aspace below a partition plate in the corresponding flow adjusting chamber. According to the fireproof door for preventing and controlling the mine fire, two airflow flowing effects are formed by the air flow adjusting device and the pressure relief device, and the flow rates of the air flow adjusting device and the pressure relief device are different, so that a stable airflow flowing trend is formed in a plane, smoke and heat flow impact the fireproof door, flows in a direction parallel to the fireproof door and then flows out to form an airflow circulating process, the smoke is fully in contact with an activated carbon layer to absorb harmful substances, the airflow is guided conveniently, and fire extinguishing is facilitated.

Description

technical field [0001] The invention relates to the technical field of mine fire prevention and control, in particular to a fire door for mine fire prevention and control. Background technique [0002] All fires that occur underground in coal mines, as well as fires that endanger underground safety near the wellhead, are called mine fires. Mine fires are divided into internal fires and external fires. Fires caused by external fire sources, such as lights, matches, smoking Fires caused by open flames such as furnaces, blasting guns, mechanical friction, electric welding, and current short circuits are called exogenous fires. Fires caused by coal spontaneous combustion are called internal fires. Internal fires account for about 75% of the total number of mine fires. When a fire occurs, due to the existence of corner-connected air passages, the air flow is relatively disordered, which is not conducive to fire handling. [0003] The mine fire door is a safety facility to preven...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the mine fire door in the prior art only has the function of cutting off the air flow, and it is inconvenient for the staff to extinguish the fire and even cause personal injury, and proposes a mine fire prevention and control fire door
