Description

Technical Field

[0001] This utility model relates to the field of dust removal technology in mineral mining, specifically a dust removal device for open-pit mining. Background Technology

[0002] During open-pit mining, a large amount of dust is generated during the processes of ore extraction, crushing, screening, and transportation. This poses a serious threat to the environment, equipment, and workers' health. Therefore, dust removal devices are needed to remove the dust, and fog cannons are the most commonly used dust removal devices.

[0003] Existing fog cannons cannot adjust the spray volume according to the size of dust particles on site, which increases water consumption and cannot guarantee dust removal effect. Furthermore, the size of the water mist particles cannot be adjusted, which cannot guarantee the best dust removal effect, thus presenting limitations.

[0004] The reason for this problem is that excessive spray volume increases water consumption and makes dust particles too wet to settle, while insufficient spray volume cannot effectively cover all dust particles, resulting in poor dust removal. The size of the water mist particles cannot be adjusted. When facing large dust particles, the smaller water mist particles will evaporate too quickly and lose their dust-suppressing effect. When facing small dust particles, large water mist particles will splash up fine dust particles during the settling process, causing secondary pollution. Therefore, we propose a dust removal device for open-pit mines to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dust removal device for open-pit mining. It solves the problems of existing fog cannons being unable to adjust the spray volume according to the size of dust particles on site, which increases water consumption and fails to guarantee dust removal effect. Furthermore, the size of the water mist particles cannot be adjusted, which also fails to guarantee the best dust removal effect, thus presenting limitations.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a dust removal device for open-pit mining, comprising a body, a water tank inside the body, a sprayer above the body, and an adjustable unit for controlling the spray size on one side of the sprayer, the adjustable unit comprising a first nozzle, a second nozzle, and a solenoid valve;

[0007] The first nozzle has a smaller nozzle diameter; the second nozzle is located on one side of the first nozzle and has a larger nozzle diameter; the first nozzle and the second nozzle are connected to the water tank; the solenoid valve is located on one side of the water tank and is used to control the fluid entering the interior of the first nozzle or the second nozzle.

[0008] Preferably, the sprayer includes a mounting frame, a motor, and a fan;

[0009] The mounting bracket is fixedly assembled inside the sprayer; the motor is fixedly assembled on one side of the mounting bracket; the fan is located on one side of the motor, and the output shaft of the motor is fixedly assembled with the fan.

[0010] Preferably, a water inlet pipe is provided on one side of the machine body, and a booster pump is provided on one side of the water inlet pipe. One side of the booster pump is connected to the water inlet pipe, and the other side of the booster pump is connected to the water tank.

[0011] Preferably, a first conduit is provided on one side of the water tank, and a first annular pipe is provided at the end of the first conduit.

[0012] Preferably, the first nozzle is disposed inside the first annular tube, and the first nozzle is distributed in a ring array.

[0013] Preferably, a second conduit is provided below the first conduit, one end of the second conduit is connected to the water tank, and the other end of the second conduit is provided with a second annular pipe.

[0014] Preferably, the second nozzle is disposed inside the second annular tube, and the second nozzle is distributed in a ring array.

[0015] Preferably, the ends of the first annular tube and the second annular tube are provided with fixing blocks, and the fixing blocks are fixedly connected to the sprayer.

[0016] Preferably, the solenoid valve includes a first solenoid valve and a second solenoid valve;

[0017] The first solenoid valve is located inside the connection between the water tank and the first conduit, and is used to control whether fluid enters the first conduit; the second solenoid valve is located inside the connection between the water tank and the second conduit, and is used to control whether fluid enters the second conduit.

[0018] This utility model discloses a dust removal device for open-pit mining, which has the following beneficial effects:

[0019] The device uses a combination of a first nozzle and a second nozzle. Because the water mist particles sprayed by the first nozzle and the second nozzle are of different sizes, it can remove dust from particles of different sizes. Furthermore, the combination of the first conduit, the second conduit, and the solenoid valve can control the amount of spray, ensuring the dust removal effect and meeting the user's needs.
