[0025] To better understand the purpose, structure, and function of this utility model, the following detailed description of a dust removal device for open-pit mining is provided in conjunction with the accompanying drawings.

[0026] like Figure 1-4As shown, this utility model discloses a dust removal device for open-pit mining, comprising a base frame 1, with casters 2 at each of the four corners of the bottom of the base frame 1. A water tank 3 and a sewage treatment tank 4 are sequentially arranged on the upper surface of the base frame 1. A dust guide pipe 5 is installed on the top of the water tank 3 via a support base. A dust suction hood 6 is provided at one end of the dust guide pipe 5, and a dust removal box 7 is connected to the other end. A suction pipe 8 is connected to the other side of the dust removal box 7. A fan 9 is provided at the end of the suction pipe 8. A dustproof net 30 is provided at the connection between the dust removal box 7 and the suction pipe 8. The dustproof net 30 can effectively prevent dust from entering the suction pipe 8. The dust collector 7 and the fan 9 are fixedly connected to both sides of the sewage treatment tank 4 via brackets. The inner cavity of the sewage treatment tank 4 is provided with a first partition 10 and a second partition 11. The first partition 10 and the second partition 11 divide the inner cavity of the sewage treatment tank 4 into a dust collection area 12, a sedimentation area 13 and a clear water area 14. The clear water area 14 is connected to a first water guide pipe 15 via a first water pump 16. The outlet of the first water guide pipe 15 is connected to the water tank 3. The clear water treated by the sewage treatment tank 4 will be transported to the water tank 3 for use through the first water pump 16 and the first water guide pipe 15, thereby realizing water recycling and greatly saving water resources. A dust collection box 22 is installed in the dust collection area 12, and a sedimentation box 23 is installed in the sedimentation area 13. Both the dust collection box 22 and the sedimentation box 23 are equipped with a drain pipe 26 extending to the bottom of the base frame 1, and a control valve is installed on the drain pipe 26. A drain pipe 21 is installed at the bottom of the dust collection box 7, and the drain pipe 21 extends into the inner cavity of the dust collection box 22. The dust collection box 22 has an inverted cone shape, and multiple evenly and orderly distributed drain outlets 27 are provided on the upper four sides of the dust collection box 22. When the water level in the dust collection box 22 overflows the drain outlets 27, the water will flow into the outside of the dust collection box 22, i.e., into the dust collection area 12. The side walls of the first partition 10 and the second partition 11 are respectively provided with a first notch 24 and a second notch 25. The second notch 25 is lower than the first notch 24. The sedimentation tank 23 has a funnel-shaped structure, and the two side walls of the sedimentation tank 23 are respectively provided with a third notch 28 and a fourth notch 29 corresponding to the first notch 24 and the second notch 25. When the water level in the dust collection area 12 overflows the first notch 24, the water will flow into the sedimentation tank 23 through the first notch 24. When the water level in the sedimentation tank 23 is higher than the fourth notch 29 and the second notch 25, the water will flow into the clear water area 14.

[0027] The dust collector 7 has a serpentine tube 19 at the top of its inner cavity and multiple atomizing nozzles 20 arranged in an orderly manner along its path at the bottom of the serpentine tube 19. The water tank 3 is connected to a second water guide pipe 17 via a second water pump 18. The second water guide pipe 17 is connected to the serpentine tube 19 and water is supplied to the serpentine tube 19 through the second water pump 18 and the second water guide pipe 17.

[0028] The working principle of this dust removal device for open-pit mining is as follows: When in use, the device is moved to the location where dust removal is needed. The moving wheels 2 are equipped with locking devices (existing technology, not detailed here). These locking devices secure the device. Then, the fan 9 is started, and dust enters the dust guide pipe 5 through the dust suction hood 6. The dust then enters the dust collection box 7 through the dust guide pipe 5. The second water pump 18 is activated, causing the atomizing nozzles 20 to spray water mist onto the dust. The dust comes into contact with the water mist and falls under gravity. The bottom of the dust collection box 7 has a conical structure, which facilitates water flow through the drain pipe 21 into the dust collection box 22. At this point, the dust will be at the bottom of the dust collection box 22. The water level in the dust collection box 22 will gradually rise. When the water level in the dust collection box 22 overflows the drain outlet 27, the water will flow into the outer side of the dust collection box 22, i.e., the dust collection area 12. When the water level in the dust collection area 12 overflows the first gap 24, the water will flow into the sedimentation box 23 through the first gap 24, so that some dust will settle in the sedimentation box 23. When the water level in the sedimentation box 23 is higher than the fourth gap 29 and the second gap 25, the water will flow into the clean water area 14. At this time, the clean water will be transported to the water tank 3 for use through the first water pump 16 and the first water guide pipe 15, thus realizing water recycling and greatly saving water resources. The dirt in the dust collection box 22 and the sedimentation box 23 can be discharged by opening the control valve.

[0029] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
