Description

Technical Field

[0001] This utility model belongs to the field of dust suppression technology in mineral exploration, specifically relating to a dust suppression device for mineral exploration engineering. Background Technology

[0002] Dust is generated during mineral exploration. Drilling, pit exploration and other construction activities will generate a lot of dust due to mechanical operations and ore crushing. This dust may spread with the air and pollute the construction site and the surrounding environment.

[0003] Vertical drilling is the most common type of drilling when drilling rocks. A lot of dust is generated during the drilling process. In order to prevent dust from polluting the construction site, a protective cover is usually placed at the drilling site. Due to the unevenness of the rock surface, there are large gaps between the protective cover and the rock surface. These gaps will cause dust to overflow, resulting in poor dust suppression.

[0004] Therefore, a dust suppression device for mineral exploration engineering is proposed. Summary of the Invention

[0005] This utility model provides a dust suppression device for mineral exploration engineering, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a dust suppression device for mineral exploration, including a dust cover; a cover located near the top of the inner wall of the dust cover; a drill bit through hole located at the center of the top of the cover; a through hole located at the bottom of the dust cover; and an overflow drainage component located in the through hole. The overflow drainage component includes: a movable column passing through the through hole; a lower rectangular channel located at the center of the bottom end of the movable column; an upper rectangular channel located at the center of the top inside the lower rectangular channel; an outer channel located on the outer wall of the movable column near the upper rectangular channel; a baffle sliding on the inner wall of the lower rectangular channel; a columnar airbag located on the outer wall of one side of the baffle; and a limiting rod located at the top of the movable column.

[0007] A water spray hole is provided on one inner wall of the dust cover near the through hole, and an atomizing nozzle is provided on one outer wall of the dust cover near the water spray hole. A branch water pipe is provided at one end of the atomizing nozzle, and a main water pipe is provided at one end of the branch water pipe. A water inlet pipe is provided on one outer wall of the main water pipe.

[0008] Furthermore, both the lower rectangular through groove and the outer through groove are connected to the upper rectangular through groove, and both the lower rectangular through groove and the upper rectangular through groove are slidably connected to the baffle.

[0009] By adopting the above technical solution, it is ensured that the baffle moves inside the lower rectangular through groove and the upper rectangular through groove, and gaps are avoided between the lower rectangular through groove and the upper rectangular through groove and the baffle, thus preventing dust from overflowing.

[0010] Furthermore, the interior of the columnar airbag is filled with gas, and the columnar airbag is located on the outside of the movable column;

[0011] By adopting the above technical solution, the columnar airbag is guaranteed to have sufficient buoyancy.

[0012] Furthermore, the baffle is made of foam board, and the baffle is adapted to the lower rectangular through groove and the upper rectangular through groove;

[0013] By adopting the above technical solution, the baffle made of lightweight foam board can move upward under the buoyancy of water, avoiding the baffle's excessive weight from being unable to float, and ensuring that the baffle moves smoothly in the lower rectangular channel and the upper rectangular channel.

[0014] Furthermore, a total of thirty-six through holes are provided, and the thirty-six through holes are axially spaced at equal intervals at the bottom of the dust cover;

[0015] By adopting the above technical solution, the through holes are evenly distributed, which facilitates the installation of multiple movable columns, thereby shielding the space between the bottom of the dust cover and the rock surface and preventing dust leakage.

[0016] Furthermore, the atomizing nozzle and the main water pipe are both connected to the branch water pipe, and the main water pipe is connected to the inlet water pipe;

[0017] By adopting the above technical solution, external water can pass through the inlet pipe, main water pipe and branch water pipe in sequence and enter the atomizing nozzle. Finally, it is atomized and sprayed out to the inside of the dust cover through the atomizing nozzle, thereby reducing dust on the inside of the dust cover.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention utilizes multiple adaptive lifting and moving movable columns on a dust cover to fill the unevenness of the rock surface, reducing the gap between the dust cover and the rock surface and minimizing dust overflow. Atomized water droplets adsorb the dust generated during drilling, effectively reducing dust. The water used for dust suppression accumulates to a certain height, and the buoyancy of the water pushes a baffle upwards, exposing the space below the lower rectangular channel for easy drainage of wastewater generated during dust suppression. The drainage outlet is located in water, preventing dust overflow and maximizing dust suppression.

The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] Reference Figure 1-6This utility model provides a dust suppression device for mineral exploration, including a dust cover 1. A cover 2 is located on the inner wall of the dust cover 1 near the top. A drill bit through-hole 3 for a mineral exploration drill bit is located at the top of the cover 2. Thirty-six through-holes 4 are located at the bottom of the dust cover 1, axially spaced evenly to ensure uniform spacing. This facilitates the installation of multiple movable columns 51, which shield the space between the bottom of the dust cover 1 and the rock surface, preventing dust leakage. Movable columns 51 from an overflow drainage assembly 5 pass through the inside of the through-holes 4. A lower rectangular through-slot 52 is located at the center of the bottom of the movable column 51, and an upper rectangular through-slot 53 is located at the center of the top of the lower rectangular through-slot 52. An outer through-slot 54 is located on one side of the outer wall of the movable column 51 near the inner side of the dust cover 1. A baffle 55 is slidably connected inside the lower rectangular through-slot 52. Both the lower rectangular through groove 52 and the outer through groove 54 are connected to the upper rectangular through groove 53, and both the lower rectangular through groove 52 and the upper rectangular through groove 53 are slidably connected to the baffle 55. This ensures that the baffle 55 moves within the lower rectangular through groove 52 and the upper rectangular through groove 53, and prevents gaps between the lower rectangular through groove 52 and the upper rectangular through groove 53 and the baffle 55, thus preventing dust from overflowing. The baffle 55 is made of foam board, and the baffle 55 is adapted to the lower rectangular through groove 52 and the upper rectangular through groove 53, using lightweight materials. The baffle 55 of the foam board can move upward under the buoyancy of water, preventing the baffle 55 from being too heavy to float, and ensuring that the baffle 55 can move smoothly in the lower rectangular through groove 52 and the upper rectangular through groove 53. A columnar air bladder 56 is provided on one outer wall of the baffle 55. The columnar air bladder 56 is filled with gas and is located outside the movable column 51 to ensure that the columnar air bladder 56 has sufficient buoyancy. A limit rod 57 is provided at the top of the movable column 51.

[0031] A water spray hole 6 is provided on one inner wall of the dust cover 1 near the through hole 4, and an atomizing nozzle 7 is provided on one outer wall of the dust cover 1 near the water spray hole 6. A branch water pipe 8 is provided at one end of the atomizing nozzle 7, and a main water pipe 9 is provided at one end of the branch water pipe 8. A water inlet pipe 10 is provided on one outer wall of the main water pipe 9. The atomizing nozzle 7 and the main water pipe 9 are both connected to the branch water pipe 8, and the main water pipe 9 is connected to the water inlet pipe 10, so that external water can pass through the water inlet pipe 10, the main water pipe 9 and the branch water pipe 8 in sequence and enter the atomizing nozzle 7. Finally, the water is atomized and sprayed out through the atomizing nozzle 7 to the inside of the dust cover 1, thereby reducing dust on the inside of the dust cover 1.

[0032] The specific implementation method is as follows: When performing dust suppression operation during the exploration drilling process, the dust cover 1 is placed on the rock surface of the required drilling hole. Under the action of gravity, the movable column 51 contacts the rock surface and fills the depressions on the rock surface through the movable column 51. When the dust cover 1 fully protects the rock at the exploration drilling hole, the outlet of the external water pump is connected to the inlet pipe 10. The external water pump draws water into the inlet pipe 10. The water passes through the main water pipe 9 and the branch water pipe 8 in sequence and enters the atomizing nozzle 7. Finally, it is atomized and sprayed out through the atomizing nozzle 7 to the inside of the dust cover 1 to achieve dust suppression of the dust inside the dust cover 1.

[0033] After the drill bit passes through the drill bit hole 3, drilling is performed on the rock. As the water mixed with dust gradually increases in the dust cover 1, the water in the dust cover 1 accumulates to a certain height. Under the buoyancy of the baffle 55 and the columnar airbag 56, the baffle 55 moves along the lower rectangular through groove 52 to the upper rectangular through groove 53. After the baffle 55 moves upward, the space below the baffle 55 in the lower rectangular through groove 52 is exposed. At this time, the water at the top of the rock and in the dust cover 1 flows out through the exposed space, realizing drainage. Since the drainage point is in the water, dust is difficult to overflow, maximizing dust reduction.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
