Underground coal mine oxygen conveying device capable of replacing air through airflow

Abstract

The invention discloses an underground coal mine oxygen conveying device capable of replacing air through airflow. The underground coal mine oxygen conveying device comprises a device shell, a main piston, a flow dividing fan blade, a movable plate and a side piston. A driving motor is welded and fixed to the device shell, a rotating disc is welded and fixed to the bottom end of a driven shaft, a connecting block is welded and fixed to the rotating disc, a limiting rod is rotationally connected to the connecting block, a supporting rod is rotationally connected to the limiting rod, a movable plate is movably connected to the supporting rod, the movable plate is movably connected to a fixed plate, and the fixed plate is connected into the device shell through screws. According to the underground coal mine oxygen conveying device capable of replacing the air through the airflow, the movable plate is arranged, the supporting rod can drive the movable plate to reciprocate up and down on the fixed plate, at the moment, fresh air and gas air can be rapidly mixed through the fixed plate, furthermore, the gas concentration in the coal mine can be rapidly and effectively diluted, and the use efficiency of the device is improved.

Description

technical field [0001] The invention relates to the technical field of coal mine safety mining, in particular to an oxygen delivery device for underground coal mines capable of air replacement through air flow. Background technique [0002] Coal mines are areas where human beings mine coal resources in coal-rich mining areas. Since most of the coal mines in our country are located underground and belong to underground coal mines, it is necessary to dig roadways underground, and then the staff need to carry out coal mining in the roadways. General coal mines The roadways are all high-gas roadways. During the construction stage of the coal mine tunneling face, the gas concentration of the working face is very high. Therefore, during the working process of the coal mine roadway, it is necessary to use an oxygen delivery device to transport fresh air into the coal mine roadway. At the same time, it is necessary to use an exhaust fan Combined with the air duct, the air diluted wi...
