Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to dust removal equipment used in open-pit mines. Background Art

[0002] A large amount of dust will be generated during the open-pit mining process. The dust flies into the air and pollutes the air around the mining site, reducing the surrounding air quality and affecting the lives of people around. The dust is inhaled by the miners, which will damage their health. At the same time, the dust floating in the air will also affect the line of sight. Therefore, it is necessary to use a dust removal device to deal with the dust, so it is necessary to use dust removal equipment for open-pit mining. The existing dust removal equipment for open-pit mining generally adopts the form of spraying, that is, the sprayed water adsorbs the dust in the air. Due to the effect of gravity, the water droplets move downward and take away the dust in the air. After the air with dust is sprayed with water, the sprayed water falls directly and cannot be reused. However, when used around the open-pit mine, due to the large spatial range of the mine, a large amount of water resources are required, which in turn causes a large waste of water resources. Therefore, in view of the above problems, a dust removal equipment for open-pit mining is proposed. Utility Model Content

[0032] Working principle: water is added to the water cavity through the water adding pipe 6, and then the fan 11 is started through the controller 4. The operation of the fan 11 forms a negative pressure inside the dust collecting pipe 9, so that the dust around the mine enters the dust collecting pipe 9 through the dust collecting cover 10, and then enters the dust removal box. The water in the water cavity is pumped to the inside of the connecting pipe 153 through the connecting pipe 152 by the water pump 151, and then sprayed to the gas with dust through the rotating nozzle 154, so that the dust in the air can be sprayed down, and the remaining large particles of dust and impurities are filtered through the filter plate 13. The used sewage is guided to a place of the through hole 16 through the inclined plate 14, and the sewage enters the water cavity through the through hole 16.

[0033] When the dust-carrying gas is collected by the dust collecting hood 10, it will first be filtered by the second filter 20. The second filter 20 can remove large stones in the air to prevent the stones from damaging the fan 11. When the second filter 20 is blocked, the second filter 20 is rotated so that the block 30 rotates inside the annular groove 31 until the block 30 corresponds to the position of the groove, and then the second filter 20 is pulled outward so that the second filter 20 is taken out for cleaning or replacement, thereby preventing the second filter 20 from being blocked and improving the filtering effect of the second filter 20 on stones.

[0034] When the equipment is not used or is used at a fixed point, it is inconvenient to park because the ground in the open-pit mine is uneven. It can be fixed by the fixing mechanism 2. First, the crank 22 is turned to drive the bidirectional threaded rod 21 to rotate, so that the threaded sleeves 24 on both sides move relative to each other. The connecting rod 25 can drive the mounting plate 26 to move up and down, so that the fixing cone 27 can penetrate into the ground or move away from the ground, thereby fixing the equipment.
