Problems solved by technology

Therefore, underground staff working in this environment for a long time will not only affect their health, but even suffocate them.
Especially when the content of methane and coal dust in the air exceeds the specified value, it may cause a gas and coal dust explosion with serious consequences
In order to ensure the health and safe production of underground workers, it is necessary to continuously exchange the dirty air in the underground roadway and working face with the fresh air on the ground, and use a centrifugal mine ventilator to improve working conditions. However, the existing ventilation device Most are fixed and cannot move

Abstract

The invention discloses a movable mine ventilation device. The movable mine ventilation device comprises a ventilation device body, a base, a spraying room, a low-frequency silencing layer and a high-frequency silencing layer. The ventilation device body is installed on the base. A frequency converter is arranged on the ventilation device body. A draught fan is arranged on the left portion of the interior of the ventilation device body. An air inlet pipe port is formed in the right end of the ventilation device body. A filter screen is arranged on the air inlet pipe port. An air outlet pipe port is formed in the left end of the ventilation device body. A water return pipe is arranged at the bottom of the spraying room. A diffusion plate is arranged at the left end of the air outlet pipe port. The low-frequency silencing layer and the high-frequency silencing layer are arranged in the diffusion plate. The low-frequency silencing layer and the high-frequency silencing layer are made of waterproof centrifugal glass wool. According to the movable mine ventilation device, through the arrangement of the spraying room, the air humidity can be increased, and the content of dust in air can be reduced, so that the air quality in a mine roadway is improved; and through the arrangement of the low-frequency silencing layer and the high-frequency silencing layer, noise can be lowered.

Description

technical field [0001] The invention relates to the field of mine electromechanical equipment, in particular to a movable mine ventilation device. Background technique [0002] At present, in coal mines, due to the impact of gas gushing, coal dust flying, personnel breathing, and pit wood decay, harmful and toxic gases continue to increase; at the same time, with the increase of well depth, the underground temperature will also rise. . Therefore, underground staff working in this environment for a long time will not only affect their health, but even suffocate them. Especially when the content of methane and coal dust in the air exceeds the specified value, it may cause a gas and coal dust explosion with serious consequences. In order to ensure the health and safe production of underground workers, it is necessary to continuously exchange the dirty air in the underground roadway and working face with the fresh air on the ground, and use a centrifugal mine ventilator to imp...
