Description

Technical Field

[0001] The present invention relates to the technical field of metal mining, and in particular to a dust reduction device and a dust reduction method thereof based on open-pit mining of metal mines. Background Art

[0002] Open-pit mining is a process of removing the covering on the ore body to obtain the required minerals. Open-pit mining can be divided into open-pit metal ore mining, open-pit coal mining, and open-pit iron ore mining. The former mainly mines non-ferrous metals, the middle mainly mines coal and some non-metallic minerals, and the latter mainly mines iron ore. Open-pit mining is a method of stripping rocks and mining ore using a certain mining process and a certain mining sequence. Open-pit mining technology is divided into intermittent, continuous and semi-continuous according to the continuity of the operation. Intermittent mining technology is suitable for various geological and rock conditions; continuous technology has high labor efficiency and is easy to realize production process automation, but can only be used for soft ore and rock; semi-continuous technology has the characteristics of both of the above, but in hard rock, it is necessary to add a mechanical rock crushing link. The mining sequence is the mutual coordination of mining and stripping in time and space. In the process of open-pit mining of metal mines, a large amount of dust will be generated due to blasting, excavation, transportation and other operations. This dust not only affects the health of the operators, but also may pollute the surrounding environment.

[0003] Traditional dust reduction methods usually use water spraying equipment to carry out dust reduction treatment. However, the nozzle of this water spraying equipment is generally installed at the highest point and can only perform simple rotation. It cannot be raised or lowered according to the actual situation and needs of the site, resulting in poor overall dust reduction effect and unable to meet the needs of open-pit mining of metal mines.

[0004] To this end, we propose a dust reduction device and a dust reduction method based on open-pit mining of metal mines. Summary of the invention

[0014] A dust reduction method based on a dust reduction device for open-pit mining of a metal mine, comprising the above-mentioned dust reduction device for open-pit mining of a metal mine, specifically comprising the following steps:

[0015] Step 1: When the automatic recognition camera detects that there is a lot of dust in the air, it automatically turns on the switch of the water pump in the water tank device. The water pump draws the water in the water tank into the lifting and rotating spline metal water pipe through the telescopic hose. The lifting and rotating spline metal water pipe transports the water to the spray nozzle and sprays it out through the spray nozzle in atomization;

[0016] Step 2: By turning on the switch of the second servo motor, the output end of the second servo motor drives the second pulley to start rotating, the second pulley drives the first pulley to start rotating through the driving belt, the first pulley drives the lifting and rotating spline metal water pipe to start rotating, the lifting and rotating spline metal water pipe drives the spray nozzle to start rotating spraying;

[0018] Step 4: While the spray nozzle is performing rotary spraying, the rotation speed and lifting speed of the spray nozzle can be accurately adjusted by controlling the rotation speed of the first servo motor and the second servo motor, so that the coverage range and spray volume of the spray can be adjusted according to different dust reduction requirements and environmental conditions to achieve the best dust reduction effect;

[0019] Step 5: During the dust reduction process, the fine and uniform water mist particles sprayed by the spray nozzle can effectively capture and settle the dust particles in the air. Due to the use of atomization spray technology, the utilization rate of water is significantly improved, while reducing the adverse effects on operators and the surrounding environment;

[0020] Step 6: When the dust reduction operation is completed, the spraying and lifting and rotating actions can be stopped by turning off the switches of the water pump, the first servo motor and the second servo motor. At this time, the spray nozzle stops spraying, the lifting and rotating spline metal water pipe and the limit lifting plate return to the initial position, and the entire dust reduction device is in standby state, ready for the next dust reduction operation.

[0022] 1. The dust reduction device and dust reduction method based on open-pit mining of metal mines realizes the precise lifting and rotation of the spray nozzle by setting an automatic lifting and rotating spray mechanism, so that the dust situation can be automatically, quickly and accurately identified according to the actual mining environment and dust distribution, and the spray range, spray direction and spray time can be flexibly adjusted, which significantly improves the dust reduction efficiency and effect. Through the coordinated work of the first servo motor and the second servo motor, the multi-angle and all-round spraying of the spray nozzle can be realized, effectively covering every corner of the open-pit mine, ensuring the uniformity and comprehensiveness of the dust reduction effect, realizing the full automation of the spray process, reducing the need for manual operation, improving working efficiency and safety, and being able to adapt to open-pit mines of different heights and sizes, with good versatility and adaptability.

A dust suppression method based on a dust suppression device for open-pit mining of metal mines, characterized in that: The dust suppression device based on open-pit mining of a metal mine comprises any one of claims 1 to 8, specifically The following steps are involved: Step 1: When the automatic recognition camera (26) detects that there is a lot of dust in the air, the water pump in the water tank device (14) is automatically turned on, and the water pump draws water in the water tank through the telescopic hose (15) into the lifting and rotating spline metal water pipe (20), and the lifting and rotating spline metal water pipe (20) transports the water to the spray nozzle (21) and sprays it out through the spray nozzle (21); Step 2: By turning on the switch of the second servo motor (25), the output end of the second servo motor (25) drives the second pulley (24) to start rotating, the second pulley (24) drives the first pulley (22) to start rotating through the driving belt (23), the first pulley (22) drives the lifting and rotating spline metal water pipe (20) to start rotating, and the lifting and rotating spline metal water pipe (20) drives the spray nozzle (21) to start rotating spraying; Step 3: By turning on the switch of the first servo motor (17), the output end of the first servo motor (17) drives the driving screw (18) to start rotating, the driving screw (18) drives the limit lifting plate (19) to start rising or falling along the guide fixed column (12), the limit lifting plate (19) drives the lifting and rotating spline metal water pipe (20) to start rising or falling, and the lifting and rotating spline metal water pipe (20) drives the spray nozzle (21) to start rising or falling, thereby achieving the purpose of adjusting the height of the spray nozzle (21), or achieving the effect of lifting and rotating the spray nozzle (21) to spray; Step 4: while the spray nozzle (21) is performing rotary spraying, the rotation speed and the lifting speed of the spray nozzle (21) can be accurately adjusted by controlling the rotation speed of the first servo motor (17) and the second servo motor (25), so that the coverage range and the spray volume of the spray can be adjusted according to different dust reduction requirements and environmental conditions to achieve the best dust reduction effect; Step 5: During the dust reduction process, the fine and uniform water mist particles sprayed by the spray nozzle (21) can effectively capture and settle the dust particles in the air. Due to the use of atomization spray technology, the utilization rate of water is significantly improved, while reducing the adverse effects on operators and the surrounding environment; Step 6: After the dust reduction operation is completed, the spraying and lifting and rotating actions can be stopped by turning off the water pump, the first servo motor (17) and the second servo motor (25). At this time, the spray nozzle (21) stops spraying, the lifting and rotating spline metal water pipe (20) and the limit lifting plate (19) return to the initial position, and the entire dust reduction device is in a standby state, ready for the next dust reduction operation.
