Abstract

The invention discloses a mine exploring ventilation device which comprises a ventilation rack. A ventilation cavity is formed in the middle of the inside of the ventilation rack, one end of the ventilation cavity is fixedly connected with a pressurizing device, the ventilation cavity is positioned on the inner side of the pressurizing device and fixedly connected with a filter net, a fan fixing frame is fixedly connected in the middle of the inside of the ventilation cavity, a power motor is fixedly connected with one side of the inside of the fan fixing frame, an output shaft of the power motor is rotatably connected with an impeller rotating shaft, impellers are mounted on the outer wall of the impeller rotating shaft, a first adjuster is mounted at the bottom of the inner wall of the fan fixing frame, and a control device is fixedly connected at a position, between the ventilation rack and the ventilation cavity, of the bottom of the inner side of the ventilation rack. The invention relates to the technical field of mine machinery. The mine exploring ventilation device achieves the objective of ventilating a mining area, ventilation efficiency and controllability of an air inlet are improved, air quality of the mining area is improved, and personnel safety is ensured more effectively.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a mine mining ventilation device. Background technique [0002] Rock drilling and blasting are generally used in mining. Pneumatic rock drills generate a lot of dust and make a lot of noise when drilling holes. In order to improve working conditions and ensure the health of workers, it is necessary to take ventilation and dust removal measures on the rock drilling face. At present, the most commonly used method of ventilation and dust removal in mines at home and abroad is local fan ventilation. It uses a motor to drive a local fan to perform extraction, press-in or mixed ventilation and dust removal on the excavation face through the fan. The disadvantage of local fan ventilation is that it is noisy, consumes electric energy, and it is inconvenient to install and move the local fan. It cannot be used in many places such as the patio operation of the climbing tank meth...
