Ventilation device for mining

Abstract

The invention discloses a ventilation device for mining, which comprises a first ventilation duct, the bottom of the first ventilation duct communicates with a second ventilation duct, a blower is fixedly connected to the right side of the first ventilation duct, and the inner wall of the blower is The top of the motor is fixedly connected with a motor, the output end of the motor is fixedly connected with a fan blade, the bottom of the motor is fixedly connected with a power regulator, and the left side of the second ventilation duct is fixedly connected with an oxygen concentration detector. The left side of the second ventilation duct and the bottom of the oxygen concentration detector are fixedly connected with a micro power supply, and the right side of the second ventilation duct is fixedly connected with an air compression box. Through the cooperation of the blower, oxygen concentration detector, air compression box, electric valve and manual knob, the present invention solves the problem that the traditional ventilation device cannot continue to provide oxygen for the underground workers after a mining accident occurs, causing most of the victims to die due to suffocation The problem.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a ventilation device for mining. Background technique [0002] Mining is the technology and science of mining mineral resources from the earth's crust and surface. In a broad sense, mining also includes the mining of coal and oil. The mining industry is an important raw material industry. Metal ore is the main raw material for the smelting industry, and non-metallic ore is an important Chemical raw materials and building materials. Mining machinery is directly used for mineral mining and enrichment operations. During the mining process, because it needs to go deep into the ground, in order to ensure the normal breathing of the workers, it is necessary to ventilate the underground. Traditional ventilation Tools are prone to leaks, leading to fires. The Chinese invention CN206093236U proposes a fire-proof ventilation duct for the mining field. Although this invention solve...

Problems solved by technology

[0003] The purpose of the present invention is to provide a ventilation device for mining, which has the advantages of still supplying oxygen to the underground after the ventilation pipe is damaged, greatly improving the survival probability of the victims, and solving the problem that the traditional ventilation device cannot continue to provide underground operation after a mining disaster occurs. Oxygen is provided to personnel, causing the majority of those affected to die from suffocation
