Ventilation device for coal mine operation

Abstract

The invention relates to the technical field of equipment for coal mines, and discloses a ventilation device for coal mine operations, which includes a mounting frame, an air outlet box is fixedly installed on the left side of the installation frame, and a main exhaust fan is fixedly installed inside the air outlet box. The side of the main exhaust fan is fixedly installed with a working time calculation device, the bottom of the main exhaust fan is fixedly connected with a first ventilation pipe, and the side of the first ventilation pipe is fixedly connected with a first lateral communication pipe. The other end of the first lateral communication pipe is fixedly connected with an auxiliary exhaust fan. The coal mine operation ventilation device, by setting the air outlet box, the first ventilation pipe, the second ventilation pipe, and the dust treatment box, makes the ventilation device change the original exhaust mode of the coal mine roadway, thereby ensuring the rapid discharge of dust and gas , to ensure the safety inside the mine, and by setting up a gas collection device, it can ensure that the gas in the coal mine is utilized and the rational use of resources is ensured.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to a coal mine operation ventilation device. Background technique [0002] Ventilation is a technology that uses natural or mechanical methods to make the wind pass through without hindrance, and reach the room or sealed environment to create a hygienic, safe and other suitable air environment. Regular ventilation can improve indoor air quality and is beneficial to health, especially in coal mines. Ventilation is more important, which is beneficial to reduce the accumulation of gas and prevent explosions. [0003] The coal mine ventilation devices currently used mainly use coal mine roadways as ventilation channels, which makes it impossible to collect and process dust during the ventilation process, and when in use, harmful gases such as gas may not be effectively discharged, and When it is discharged, it directly leads to the outside air. If there is an open flame at ...

AI Technical Summary

Problems solved by technology

[0003] The coal mine ventilation devices currently used mainly use coal mine roadways as ventilation channels, which makes it impossible to collect and process dust during the ventilation process, and when in use, harmful gases such as gas may not be effectively discharged, and When it is discharged, it directly leads to the outside air. If there is an open flame at the air outlet, it may cause an explosion, and when it is ventilated, a large amount of dust may accumulate in the coal mine, and it is impossible to clean the dust. Settlement treatment may be inhaled by operators, which will affect people's lungs. If dust is inhaled outside the mine, it will act on the fan, which will cause damage to the fan for a long time

[0004] During the operation of the fan, a single machine is generally used for operation, which shortens the life of the fan. If the single machine is damaged for a long time, it will cause unfavorable ventilation in the coal mine, which will cause insufficient ventilation in the mine, and even cause the entire mine to be damaged. stop operations, resulting in economic losses
