Safe ventilation device for coal mine and working method

Abstract

The invention discloses a safety ventilation device for a coal mine and a working method, and particularly relates to the technical field of coal mine ventilation equipment. The safety ventilation device comprises a base installed at a mine outlet, a flow guide driving mechanism is arranged at the top of the base, a flow division air outlet mechanism is arranged at the top of the flow guide mechanism, and the flow guide driving mechanism comprises an installing base installed at the top of the base. According to the safe ventilation device, through corresponding cooperative use of all structures, the stability of a structure during installation can be ensured, when air is sprayed out, conveyed airflow is blocked through an aeration head, dust inside a mine is prevented from being diffused due to the airflow, through the design of the arc-shaped cross sections of guide vanes and the cross section shape of a guide air bellow, the effeiciency of air extraction of the device is increased, meanwhile, cold air generated by a refrigeration sheet can be brought into all corners of the mine through mutual cooperation of a flow dividing filter box, a flow dividing pipe and the aeration head during air conveying, the interior of the mine is cooled, and potential safety hazards are avoided.

Description

technical field [0001] The invention relates to the technical field of coal mine ventilation equipment, more specifically, the invention relates to a coal mine safety ventilation device and a working method. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the distance to the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. [0003] Among them, in the process of underground coal mine mining, people need to go down to the mine for mining. Because the air inside the mine is relatively thin, there is a lot of dust inside the mine, and a large amount of dust will accumulate in the coal mine, which may be inhaled by the operators. , which affects people's lungs, ventilation equipment is usually installed in the mine to extract and transpor...

[0003] Among them, in the process of underground coal mine mining, people need to go down to the mine for mining. Because the air inside the mine is relatively thin, there is a lot of dust inside the mine, and a large amount of dust will accumulate in the coal mine, which may be inhaled by the operators. , which affects people's lungs, ventilation equipment is usually installed in the mine to extract and transport the air inside the mine. If the air flow is directly transported to the mine, the dust inside the mine will be due to the impact force of the air transport. Dust is generated, and due to the deep inside of the mine, the air is thin and the air flow cannot circulate, resulting in a high temperature inside the mine, which is relatively stuffy, and long-term mining work is likely to make the staff faint. Therefore, a kind of Coal mine safety ventilation device
