Description

Technical Field

[0001] This utility model belongs to the technical field of dust control devices, specifically relating to a dust control device for underground mining in metal mines. Background Technology

[0002] A mine is an independent production and operation unit that extracts ore. A mine mainly includes one or more mining workshops (or pitheads, open-pit mines, etc.) and some auxiliary workshops. Most mines also include ore dressing plants. During the mining process, a large amount of dust is generated, which can easily cause environmental pollution. Therefore, dust control is necessary.

[0003] Patent application number 202222909065.0 discloses a dust control device for mining operations, including a base, a water storage tank fixedly connected to the upper end of the base, a water pump box fixedly connected to one side of the upper end of the water storage tank, a dust suppression component fixedly connected inside the water pump box, a cover plate connected to the upper end of the water pump box by screw threads, a support rod fixedly connected to one side of the upper end of the cover plate, and an electric push rod fixedly connected to the other side of the upper end of the cover plate.

[0004] The aforementioned dust control device for mining uses water pumps and nozzles to spray water mist to adsorb and remove dust from the air. Although it can effectively treat dust in the air in the short term, once the moisture in the dust dries, the dust on the ground will still float due to being trampled by mining equipment or personnel. It cannot eliminate the amount of dust in the mining environment and has poor long-term dust treatment effect. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a dust control device for underground mining of metal mines. This device aims to solve the technical problem that, under existing technologies, even after the moisture in the dust has dried, the dust on the ground will still float due to being trampled by mining equipment or personnel, making it impossible to eliminate the amount of dust in the mining environment and resulting in poor long-term dust treatment effects.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a dust control device for underground mining of metal mines. The dust control device includes a water storage tank and an air circulation box installed on the top of the water storage tank. A first drainage frame and a second drainage frame are respectively installed at both ends of the air circulation box, and a fan is embedded in the air circulation box. A filter screen corresponding to the second drainage frame is embedded and fixed in the air circulation box. A sludge storage tank corresponding to the inclined surface of the filter screen is provided on the bottom wall of the air circulation box. Atomizing pipes are installed at equal intervals on both sides of the inner wall of the first drainage frame.

[0009] When using this technical solution, an air circulation box is installed at the top of the water storage tank. After the fan in the air circulation box is started, it draws in air containing dust. The dust in the air is filtered by the filter plate and discharged from one side of the first drainage frame. The airflow generated by the air sprays atomized water from the atomizing pipe, which adsorbs the dust in the outside air. By adsorbing the dust in the air through the blown atomized water, the dust in the air can be quickly treated in a short period of time. At the same time, the dust in the air is adsorbed and blocked by the filter plate, reducing the amount of dust in the mining environment and improving the long-term treatment effect of dust. By installing a sludge storage tank at the bottom of the water storage tank, the dust on the inclined surface of the filter screen falls into the sludge storage tank due to gravity. Water from the second drainage frame is discharged from the flushing pipe through the water supply pipe to wash the dust adsorbed in the filter screen. The washed dust flows into the sludge storage tank, which facilitates the treatment and collection of dust in the filter screen and improves the treatment effect of dust in the filter screen.

[0010] Preferably, a base is fixedly installed at the bottom of the water storage tank, and multiple rollers are installed in a rectangular array at the bottom of the base, and a push rod is fixedly installed at the top of the base.

[0011] Furthermore, water pipes are installed on the side walls of both the first and second drainage racks, and the bottom ends of both water pipes extend into the water storage tank where water pumps are installed.

[0012] Furthermore, a water inlet pipe is installed at the top of the water storage tank, and a one-way valve is embedded in the water inlet pipe.

[0013] Furthermore, protective nets are embedded in both ends of the fan, and the inner wall of the air circulation box is fixed with protrusions that fit against the filter screen.

[0014] Furthermore, the hollow cavities of both the first and second drainage racks are configured as conveying channels, and flushing pipes are installed at equal intervals on the top wall of the second drainage rack.

[0015] Furthermore, each of the multiple flushing pipes corresponds to the inclined surface of the filter screen, and both the flushing pipe and the atomizing pipe are threaded with nozzles.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention features an air circulation box at the top of a water storage tank. When the fan in the air circulation box is started, it draws in air containing dust. The dust in the air is filtered by the filter plate and discharged from one side of the first drainage frame. The airflow generated by the air sprays atomized water from the atomizing tube to adsorb dust in the external air. By adsorbing dust in the air with the blown-out atomized water, the dust in the air can be quickly processed in a short period of time. At the same time, the dust drawn in is adsorbed and blocked by the filter plate, reducing the amount of dust in the mining environment and improving the long-term dust treatment effect.

[0019] By setting a sludge storage tank at the bottom of the water storage tank, the dust on the inclined surface of the filter screen falls into the sludge storage tank due to gravity. Water from the second drainage rack is discharged through the water supply pipe to wash the dust adsorbed in the filter screen. The washed dust flows into the sludge storage tank, which facilitates the treatment and collection of dust in the filter screen and improves the dust treatment effect of the filter screen.

Detailed Implementation

[0026] 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.

[0027] This specific embodiment is a dust control device for underground mining in metal mines, and its structural schematic diagram is shown below. Figure 1 and Figure 2 As shown, the dust control device for underground mining of metal mines includes a water storage tank 2 and an air circulation box 6 installed at the top of the water storage tank 2. A first drainage frame 3 and a second drainage frame 4 are installed at both ends of the air circulation box 6, and a fan 9 is embedded in the air circulation box 6. A filter screen 12 corresponding to the second drainage frame 4 is embedded and fixed in the air circulation box 6. A sludge storage tank 16 corresponding to the inclined surface of the filter screen 12 is provided on the bottom wall of the air circulation box 6. Atomizing pipes 10 are installed at equal intervals on both sides of the inner wall of the first drainage frame 3.

[0028] A base 1 is fixedly installed at the bottom of the water storage tank 2. Multiple rollers 8 are installed in a rectangular array at the bottom of the base 1, and a push rod 5 is fixedly installed at the top of the base 1. Water pipes 7 are installed on the side walls of the first drainage frame 3 and the second drainage frame 4. The bottom ends of the two water pipes 7 extend into the water storage tank 2 and are equipped with water pumps. A water inlet pipe 14 is installed at the top of the water storage tank 2. A one-way valve 15 is embedded in the water inlet pipe 14. After the fan 9 in the air circulation box 6 is started, it draws in air containing dust. The dust in the air is filtered by the filter plate and discharged from one side of the first drainage frame 3. The airflow generated by the air sprays out the atomized water in the atomizing pipe 10 to adsorb the dust in the outside air. The blown atomized water adsorbs the dust in the air and quickly processes the dust in the air in a short period of time. At the same time, the dust in the air is adsorbed and blocked by the filter plate, reducing the amount of dust in the mining environment.

[0029] Protective nets 11 are embedded in both ends of the blower 9. The inner wall of the air circulation box 6 has protrusions that fit against the filter screen 12, blocking the flushing water and allowing it to flow into the sludge storage tank 16. The hollow cavities of the first drainage frame 3 and the second drainage frame 4 are both configured as conveying channels 17. Flushing pipes 13 are equidistantly installed on the top wall of the second drainage frame 4, with each flushing pipe 13 corresponding to the inclined surface of the filter screen 12. Both the flushing pipes 13 and the atomizing pipe 10 are threaded with nozzles 18. Dust on the inclined surface of the filter screen 12 falls into the sludge storage tank 16 due to gravity. Water from the second drainage frame 4 is discharged through the flushing pipes 13 via the water supply pipe 7 to flush the dust adsorbed in the filter screen 12. The flushed dust then flows into the sludge storage tank 16.

[0030] Working principle: When using the device of this technical solution, the fan 9 in the air circulation box 6 draws in air containing dust after starting. The dust in the air is filtered by the filter plate and discharged from one side of the first drainage frame 3. The airflow generated by the air sprays the atomized water in the atomizing pipe 10 to adsorb the dust in the external air. The blown atomized water adsorbs the dust in the air and quickly processes the dust in the air in a short period of time. At the same time, the dust in the air is adsorbed and blocked by the filter plate, reducing the amount of dust in the mining environment. The dust on the inclined surface of the filter screen 12 falls into the sludge storage tank 16 under the influence of gravity. When cleaning the filter screen 12, the water pump water pipe 7 is started to discharge the water in the second drainage frame 4 from the flushing pipe 13 to wash the dust adsorbed in the filter screen 12. The washed dust flows into the sludge storage tank 16, which facilitates the treatment and collection of dust in the filter screen 12 and improves the treatment effect of dust in the filter screen 12.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
