Real-time dust falling device for mineral exploitation, and operation method thereof

Abstract

The invention belongs to the technical field of mineral exploitation, and particularly relates to a real-time dust falling device for mineral exploitation, and an operation method thereof.The real-time dust falling device comprises a movable base and an annular water pipe, the outer wall of the annular water pipe is fixedly connected with flow dividing pipes at equal intervals, the outer wall of each flow dividing pipe is provided with a spraying assembly, and the flow dividing pipes are communicated with the annular water pipe. The spraying assembly is arranged, the spraying assembly is composed of the annular water pipe, the flow dividing pipes, a long pipe and an extending pipe, when dust falling operation is conducted on mineral exploitation, an air cylinder is adjusted to adjust the extending pipe to the proper height, then water is sprayed through spraying holes in the extending pipe, the extending pipe is in a step shape, and the spraying holes are annularly distributed in the outer wall of the extending pipe, so that when water is sprayed, the water is sprayed out from the spraying holes at different angles to form independent coverage surfaces which are diffused outwards, the coverage area of the water is expanded to the maximum, and maximum dust falling is realized.

Description

technical field [0001] The invention relates to the technical field of mineral mining, in particular to a real-time dust suppression device and operation method for mineral mining. Background technique [0002] Minerals generally refer to all natural mineral or rock resources buried underground (or distributed on the surface, or weathered rocks, or rock deposits) available for human use; minerals can be divided into metals, non-metals, combustible organics, etc. It is a non-renewable resource; in the process of mineral mining, a large amount of dust and impurities are generated due to the work of mining equipment, and dust suppression devices are required at this time. [0003] A large amount of dust and impurities will be produced in the existing mining process, which will cause great harm to the staff working in the mine. Therefore, it is necessary to carry out dust reduction treatment through the dust reduction device. The existing dust reduction device The dust is adsor...

AI Technical Summary

Problems solved by technology

[0003] A large amount of dust and impurities will be produced in the existing mining process, which will cause great harm to the staff working in the mine. Therefore, it is necessary to carry out dust reduction treatment through the dust reduction device. The existing dust reduction device The dust is adsorbed and dropped by spraying the water body. During the spraying process of the water body, its trajectory in the air falls in a parabola, which limits the dust reduction range and effect of the water body. At the same time, the water body is sprayed at a high speed. , the airflow generated will drive the dust away from the dust-falling point, resulting in further weakening of the dust-falling effect and strengthening the pollution of the dust to the environment
