[0002] Open-pit mines are mineral resources mined by open-pit mining. According to the terrain and burial conditions of the ore deposits, open-pit mines can be divided into hillside open-pit mines and sunken open-pit mines. According to the mining process, they can be divided into mechanical mining and hydraulic mining. Hydraulic mining is only used for mining soft ore deposits, while mechanical mining is widely used. In mechanically mined open-pit mines, the ore rock is divided into horizontal layers of a certain thickness, and stripping and mining are carried out layer by layer from top to bottom. The general term for the mining pits, steps and open-pit ditches formed by mining is called an open-pit mine. The main machinery used in open-pit mines are punchers, excavators, cars, electric locomotives, bulldozers, etc.

[0003] During open-pit mining, large-scale dust will appear. In order to reduce its impact on the surrounding environment and the physical and mental health of workers, it is necessary to set up multiple dust removal devices around the mining area. The existing dust removal device is mainly a fog cannon, and dust will be continuously generated. The fog cannon needs to run for a long time, and the atomized water will accumulate on the ground of the working area, causing the ground to be muddy, which is not conducive to the walking of transport vehicles and mining personnel.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to provide a water-collecting open-pit mining dust reduction device to solve the shortcomings of the existing technology. Utility Model Content

[0023] In this embodiment, refer to the attached Figure 1-2 The water-collecting open-pit mining dust reduction device comprises a dust reduction box body 1 and a water collection box body 2. The dust reduction box body 1 and the water collection box body 2 are connected through a water inlet pipe 3 and a sewage discharge pipe 4. A dust suction channel 5 is installed at the top center of the dust reduction box body 1. A swirl fan 6 is installed inside the dust suction channel 5. A dust reduction cleaning system 7 is installed inside the dust reduction box body 1.

[0024] The present application is used to reduce dust in an open-pit mining work area. First, the dust suction channel 5 on the top of the dust reduction box 1 is aligned with the work area, so that the dust is sucked into the interior of the dust reduction box 1 through the dust suction channel 5 by the action of the swirl fan 6, and then the dust is reduced through the dust reduction cleaning system 7. The atomized dust after treatment enters the water collecting box 2 for filtration, and the water collecting box 2 provides a water source for atomized dust reduction.

[0025] The dust reduction and cleaning system 7 includes an annular spray disc 71, which is fixedly mounted on the top of the dust reduction box 1 and surrounds the dust suction channel 5. The inner bottom of the dust reduction box 1 is provided with a spherical box bottom 72. A driving motor 73 and a reducer 74 are installed below the dust reduction box 1. The driving motor 73 and the reducer 74 cooperate with each other. A rotating shaft 75 is fixedly mounted on the output end of the reducer 74. The top end of the rotating shaft 75 rotates through the spherical box bottom 72 and is fixedly mounted with an arc-shaped cleaning plate 76. An arc-shaped cleaning surface 77 is provided on the arc-shaped cleaning plate 76, and the arc-shaped cleaning surface 77 fits the spherical box bottom 72.

[0026] The dust reduction and cleaning system 7 sprays atomized water through the annular spray disc 71 to atomize the open-pit mining dust sucked into the dust suction channel 5, and then scrapes and cleans the atomized open-pit mining dust attached to the spherical box bottom 72 through the arc-shaped cleaning plate 76. The spherical box bottom 72 facilitates the sliding of the atomized dust. At the same time, the arc-shaped cleaning surface 77 fits the spherical box bottom 72, and the driving motor 73 and the reducer 74 drive the rotating shaft 75 and the arc-shaped cleaning plate 76 to rotate, so that the entire spherical box bottom 72 can be cleaned without manual cleaning.

[0027] A plurality of nozzles 8 are installed at the bottom of the annular spraying disc 71 , and the water outlet ends of the nozzles 8 are all inclined toward the dust suction channel 5 .

[0028] The water sprayed from the nozzle 8 can be used to atomize and dust-relieve the dust sucked into the dust-relief passage 5 around the dust-relief passage 5, thereby achieving a higher dust-relief efficiency.

[0029] A sealing sheet 9 is installed on the arc-shaped cleaning plate 76 at the intersection with the rotating shaft 75 and the spherical box bottom 72. The sealing sheet 9 can prevent the atomized liquid from leaking through the gap between the spherical base and the rotating shaft 75.

[0030] A circulation valve 10 is installed on the circulation water pipe, and the circulation valve 10 can control whether the liquid inside the filter box is circulated.

[0031] The water collecting box 2 includes a filter box 21 and a water storage box 22, a partition plate 23 is provided between the filter box 21 and the water storage box 22, a filter layer 24 is installed inside the filter box 21, the bottom of the dust reduction box 1 is connected to the filter box 21 through a sewage pipe 4, a circulating water pump 25 is installed inside the filter box 21, and the circulating water pump 25 is connected to the water storage box 22 through a circulating water pipe, and a water inlet pump 26 is installed inside the water storage box 22, and the water inlet pump 26 is connected to the annular spray plate 71 through the water inlet pipe 3.

[0032] The filter box 21 is connected to the bottom of the dust reduction box 1 through the sewage pipe 4, and the atomized open-pit mining dust cleaned by the arc cleaning plate 76 is sent to the filter layer 24 inside the filter box 21 for filtration. The filtered liquid can be pumped to the inside of the water storage tank 22 by the circulating water pump 25 for continued circulation. The water storage tank 22 sends the water source in the box to the annular spray plate 71 for dust reduction spraying through the water inlet pump 26 and the water inlet pipe 3.

[0033] The utility model uses the dust reduction and cleaning system 7 to atomize and reduce dust from open-pit mining, thereby preventing atomized water from accumulating on the ground in the working area and causing the ground to be muddy. Then, the atomized dust on the spherical box bottom 72 is scraped and cleaned by the arc-shaped cleaning plate 76, so that the atomized dust enters the interior of the filter box 21 for filtration. The filtered water can still be collected and recycled, thereby achieving the effect of water collection and circulation and saving water resources.
