Description

Technical Field

[0001] This utility model belongs to the field of dust control technology, specifically relating to a dust control device for open-pit mines. Background Technology

[0002] During open-pit mining, drilling, blasting, loading, transportation, and crushing operations all generate large amounts of dust. This dust spreads over a wide area and lasts for a long time, posing a serious threat to the ecological environment and the health of workers. Traditional dust control technologies mainly rely on fixed sprinkler systems or mobile water trucks, but these have significant limitations. Fixed equipment has fixed nozzle positions, making it difficult to adapt to the dynamically changing operating scenarios in open-pit mines (such as moving loaders or blasted piles at different heights), leading to localized dust concentrations exceeding standards. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dust control equipment for open-pit mines, which aims to solve the problem that the existing traditional dust control technology mainly relies on fixed spray systems or mobile sprinkler trucks, but has significant limitations. Fixed equipment has fixed nozzle positions, which makes it difficult to adapt to the dynamic and changing operating scenarios of open-pit mines.

[0005] (2) Technical solution

[0006] To address the aforementioned technical problems, this utility model provides a dust control device for open-pit mines, comprising a mobile frame, a spray plate, and a support frame. Two sets of symmetrically distributed support frames are positioned above the mobile frame, spaced apart, with a spray plate slidably mounted between them. A drive back plate protrudes from the back of each spray plate. Inner sliding plates are vertically slidably mounted inside each support frame, located on either side of the drive back plate. The drive back plate and the upper positions of the inner sliding plates are rotatably connected. A rotating groove is formed on the surface of any one set of inner sliding plates facing the drive back plate, and a rotating shaft is rotatably mounted inside the rotating groove. The end of the rotating shaft is fixedly connected to the drive back plate. The spray plate's lifting range covers the typical operating height of open-pit mines, adapting to different dust generation locations in scenarios such as loading, blasting, and crushing, avoiding localized exceedances caused by fixed nozzles. The rotating spray plate can quickly align with the dust diffusion direction, improving the contact efficiency between water mist and dust and reducing resource waste.

[0007] Preferably, a threaded column is vertically rotatably mounted inside the support frame, a drive motor is fixed at the bottom of the support frame, the output shaft of the drive motor is connected to the threaded column, and a threaded hole adapted to the threaded column is vertically opened inside the inner slide plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This specific embodiment is a dust control device for open-pit mines, and its structural schematic diagram is shown below. Figure 1 As shown, it includes a mobile frame 1, a spray plate 4 and a support frame 3. Two sets of symmetrically distributed support frames 3 are provided on the top of the mobile frame 1. The two sets of support frames 3 are spaced apart and the spray plate 4 is slidably installed between them. A drive back plate 10 protrudes from the back of the spray plate 4.

[0024] Reference Figure 1 , Figure 3 , Figure 4 An inner sliding plate 7 is vertically slidably installed inside the support frame 3. The inner sliding plate 7 is located on both sides of the drive back plate 10, and the drive back plate 10 and the inner sliding plate 7 are rotatably connected to each other at their upper positions. A rotating groove 14 is opened on the surface of any one set of inner sliding plates 7 facing the drive back plate 10. A rotating shaft 12 is rotatably installed inside the rotating groove 14, and the end of the rotating shaft 12 is fixedly connected to the drive back plate 10. A threaded column 8 is vertically rotatably installed inside the support frame 3. A drive motor is fixed at the bottom of the support frame 3, and the output shaft of the drive motor is connected to the threaded column 8. A threaded hole 13 adapted to the threaded column 8 is vertically opened inside the inner sliding plate 7. Multiple sets of limiting holes 11 are distributed around the outer wall of the rotating shaft 12. A limiting screw 9 is vertically inserted into the upper surface of the support frame 3, and the bottom of the limiting screw 9 is inserted into the limiting hole 11. A transmission pipe 2 is vertically installed on the side wall of the spray plate 4. Multiple sets of inner pipes are horizontally spaced inside the spray plate 4, and the inner pipes are connected to the transmission pipe 2.

[0025] Reference Figure 1 , Figure 2 The bottom of the transmission pipe 2 is connected to the liquid inlet pipe 5. The surface of the spray plate 4 is equipped with multiple sets of nozzles, which are connected to the inner pipe. The bottom of the mobile frame 1 is equipped with casters.

[0026] Working principle: After the drive motor starts, it drives the threaded column 8 inside the support frame 3 to rotate. The inner slide plate 7 engages with the threaded column 8 through the internal threaded hole 13. When the threaded column 8 rotates, it slides vertically along the support frame 3. During the sliding process of the inner slide plate 7, the spray plate 4 is driven to rise and fall synchronously through the drive back plate 10, so as to realize the flexible adjustment of the spray height from low to high position, matching the dust generation position of different operation scenarios, such as the loader working face and the top of the blasting pile.

[0027] The rotating shaft 12 is installed in the rotating groove 14 of the inner slide plate 7, and its end is fixedly connected to the drive back plate 10.

[0028] When the rotating shaft 12 is manually driven to rotate, it drives the drive back plate 10 and the spray plate 4 to rotate around the axis of the rotating shaft 12, thereby adjusting the spray angle. The current angle of the spray plate 4 is fixed by inserting the limit screw 9 through the support frame 3 and into the limit hole 11 of the rotating shaft 12, preventing the angle from shifting due to vibration or wind during operation.

[0029] The liquid inlet pipe 5 is connected to a water source (tap water) or a dust suppressant storage tank. A pump (not shown in the figure) delivers the liquid to the transmission pipe 2. The liquid is then diverted through the transmission pipe 2 to multiple sets of horizontal inner pipes inside the spray plate 4, and finally atomized and sprayed out from the surface nozzles to form a dust suppressant mist covering the target area. The bottom of the mobile frame 1 is equipped with wheels, which can be manually pushed or driven by a motor to achieve rapid transfer of the equipment in the mining area. After reaching the working position, the rigid connection between the support frame 3 and the mobile frame 1 ensures the stability of the equipment and adapts to the complex terrain of open-pit mines (such as slopes and potholes).
