A metal mine underground ventilation device

Abstract

The invention discloses an underground ventilation device for metal mines, comprising a main fan, the output end of the main fan is connected with an air inlet pipe, and one end of the air inlet pipe is connected with an underground ventilation assembly capable of ventilating underground in multiple directions to achieve uniform ventilation. And the bottom of the downhole ventilation component is connected with a metal dust treatment component that screens and treats the downhole metal dust. The present invention realizes rotating ventilation through the set ventilation component, and the multiple ventilation pipes in this solution realize rotating ventilation while performing rotation ventilation. , through the rotation component, a single ventilation pipe is driven to rotate and ventilate at the same time, which is convenient for the ventilation pipe to fully contact with the underground air during the ventilation process, which is convenient to improve the ventilation efficiency. Sieving the metal dust after falling dust is beneficial to the centralized collection and treatment of the metal dust.

Description

technical field [0001] The invention relates to the technical field of mine ventilation equipment, in particular to an underground ventilation device for metal mines. Background technique [0002] The basic tasks of mine ventilation are: to supply enough fresh air underground to meet the oxygen needs of personnel; to dilute harmful gases and dust underground to ensure safe production; to adjust the underground climate and create a good working environment. In order to distribute the underground air flow along the designated route, it is necessary to build structures that guide and control the air flow in certain roadways, that is, ventilation facilities, which are divided into facilities that guide the air flow and block the air flow. The ventilation system of new large-scale mines is mainly of diagonal type and partition type, and the production mine of reconstruction and expansion is mainly of mixed type. For the ventilation in metal mines, it is necessary to consider that...

Problems solved by technology

[0003] When the existing mechanical method is used to ventilate the underground of metal mines, through the main fan connected to the outside of the mine, the main fan passes the outside wind into the mine, and the air in the mine is ventilated and replaced. At the same time, through the processing equipment of the air pump, Exhaust the waste gas in the mine out of the mine, but in the ventilation process, the mouth of the mine is ventilated. Since the ventilation pipe has a certain length, it is only ventilated through the mouth of the pipe, and the air from the outside is relatively slow. It is not conducive to the outside ventilation air to fully contact with the air in the mine after entering the mine, and it is not convenient to fully and quickly ventilate the underground air of the metal mine, and to ventilate through the nozzle, the metal dust mixed in the underground air is concentrated in the pipe It is not conducive to the collection and treatment of metal dust distributed in the ventilation ducts. Therefore, we propose a metal mine underground ventilation device
