Environment-friendly ventilation device for air in mining environment

Abstract

The invention relates to an environment-friendly ventilation device for air in a mining environment. The environment-friendly ventilation device for the air in the mining environment comprises a ventilation pipe, two filtering parts are telescopically inserted on the ventilation pipe, the ventilation pipe is provided with an adjusting part connected with the two filtering parts, the ventilation pipe is provided with a cleaning part, one end of the cleaning part extends into the ventilation pipe and is in contact with the filtering parts, and the ventilation pipe communicates with a transmission part which is connected with the cleaning part and is used for driving the cleaning part to move along the vertical direction; a filtering device in the ventilation process in the mine is improved, the adjusting part is connected with the two filtering parts, the two filtering parts can alternately filter the ventilation pipe, in other words, the filtering parts can be replaced in the operation process of the ventilation device, the replacement process can be completed only by driving a winding cylinder to rotate through a driving part, a worker only needs to clean and replace the pulled-out filtering part, so that the replacement process of the filtering device is accelerated, a machine does not need to be shut down, and the coal mining efficiency is improved.

Description

technical field [0001] The invention relates to the field of mining ventilation technology, in particular to an environment-friendly ventilation device for the air in the mining environment. 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] The vast majority of coal mines in my country belong to underground coal mines, and in underground coal mines, ventilation systems are usually required to supply enough fresh air underground to meet the needs of personnel for oxygen, and to dilute toxic and harmful gases and dust underground to ensure safety. Production. [0004] However, during the long-term use of the existing coal mine ventilation device, more dust and ...

Problems solved by technology

[0004] However, during the long-term use of the existing coal mine ventilation device, more dust and fine cinders in the air will usually accumulate inside the flow channel of the ventilation, and subsequent manual cleaning or replacement of the filter components is required. The process is inconvenient, and the filter part needs to be disassembled. During the disassembly process, the ventilation device needs to be shut down before operation. After the ventilation device is shut down, the coal mining efficiency will be directly reduced.
