Coal mine operation ventilation device

Abstract

The invention relates to the technical field of coal mine equipment, and discloses a coal mine operation ventilation device which comprises a mounting frame. An air outlet box is fixedly mounted on the left side face of the mounting frame, a main exhaust fan is fixedly mounted in the air outlet box, a working time calculation device is fixedly mounted on the side face of the main exhaust fan, thebottom of the main exhaust fan fixedly communicates with a first ventilation pipe, the side face of the first ventilation pipe fixedly communicates with a first lateral communication pipe, and the other end of the first lateral communication pipe fixedly communicates with an auxiliary exhaust fan. According to the coal mine operation ventilation device, by arranging the air outlet box, the first ventilation pipe, a second ventilation pipe and a dust treatment box, an original air exhaust mode of a coal mine roadway is changed through the ventilation device, then it is guaranteed that dust andgas are rapidly exhausted, and the safety in a mine is guaranteed; and a gas collecting device is arranged, so that gas of the coal mine can be utilized, and reasonable utilization of resources is guaranteed.

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
