Description

Technical Field

[0001] This utility model relates to the field of atomization dust removal technology, and in particular to an atomization dust removal device for underground mining. Background Technology

[0002] Atomized dust removal is a technology that captures and removes dust from the air by atomizing water. It is widely used in industries such as industry, construction, and mining. When conducting underground mining operations, a large amount of smoke and dust is generated in the mining area. When using existing atomized dust removal devices to remove dust, water mist is sprayed at the dust source, and then a dust suction mechanism adsorbs the dust with water droplets attached. However, because the dust covers a large area, the suction power of the dust suction device alone is insufficient to collect the dust, resulting in a small dust removal area and low dust removal efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that directly use atomizing nozzles to suppress dust, resulting in limited atomization area and low dust treatment efficiency. Therefore, this invention proposes an atomizing dust removal device for underground mining.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a dust suppression device for underground mining, including a base platform and a support ring fixedly connected to the base platform. A gear ring is rotatably connected to the base platform, and a drive mechanism for driving the gear ring to rotate is fixedly connected to the base platform. A conical gear disk is fixedly connected to the surface of the gear ring. Several rotating shafts are evenly rotatably connected to the support ring. A conical gear is fixedly connected to the circumferential side of each rotating shaft. The conical gear meshes with the conical gear disk. A fan blade is fixedly connected to the end of each rotating shaft near the center of the base platform. A water supply pipe is fixedly connected to the support ring, and a dust suppression component is connected to the end of the water supply pipe.

[0006] Preferably, the dust suppression component includes a ring pipe connected to a water supply pipe, and a plurality of water supply rings are connected to the circumferential side of the ring pipe, each of the water supply rings being coaxially arranged with a corresponding rotating shaft.

[0007] Preferably, a plurality of atomizing nozzles are uniformly connected on the water conveying ring, and a flow guide is fixedly connected between the atomizing nozzles.

[0008] Preferably, the flow guide is provided with openings at both ends, and the opening near the center of the base is larger than the opening on the other side.

[0009] Preferably, a gathering bucket is fixedly connected to the base platform, a filter plate is fixedly connected to the gathering bucket, a flexible hose is connected to the gathering bucket, and a fan is connected to the flexible hose.

[0010] Preferably, the driving mechanism includes a drive motor, and a drive gear is fixedly connected to the output end of the drive motor, the drive gear meshing with a gear ring.

[0011] The beneficial effects of the atomizing dust removal device for underground mining proposed in this utility model are as follows: This utility model uses a conical toothed disc to rotate, which drives a conical gear to rotate. The rotation of the conical gear drives each fan blade to rotate. The rotation of the fan blades creates a negative pressure, which guides the dust outside the base to the axis of the base through a guide shroud. When the dust passes through the guide shroud, it is sprayed and reduced by the atomizing nozzle. Compared with the direct spray dust reduction method, this method has a stronger dust handling capacity and better dust reduction ability. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1

[0022] Reference Figure 1-6This utility model is a dust removal device for underground mining, including a base platform 1 and a support ring 2 fixedly connected to the base platform 1. A toothed ring 4 is rotatably connected to the base platform 1. A drive mechanism for driving the toothed ring 4 to rotate is fixedly connected to the base platform 1. A conical toothed disk 5 is fixedly connected to the surface of the toothed ring 4. Several rotating shafts 6 are evenly rotatably connected to the support ring 2. A conical gear 7 is fixedly connected to the circumferential side of the rotating shaft 6. The conical gear 7 meshes with the conical toothed disk 5. A fan blade 8 is fixedly connected to the end of the rotating shaft 6 near the axis of the base platform 1. A water supply pipe 9 is fixedly connected to the support ring 2. A dust suppression component is connected to the end of the water supply pipe 9.

[0023] The dust suppression component includes a ring pipe 10, which is connected to a water supply pipe 9. Several water supply rings 11 are connected to the circumference of the ring pipe 10. Each water supply ring 11 is coaxially arranged with the corresponding rotating shaft 6. Several atomizing nozzles 13 are evenly connected to the water supply rings 11. A guide shroud 12 is fixedly connected between the atomizing nozzles 13. The guide shroud 12 has openings at both ends. The opening of the guide shroud 12 near the center of the base 1 is larger than the opening on the other side.

[0024] The drive mechanism includes a drive motor, and a drive gear 3 is fixedly connected to the output end of the drive motor. The drive gear 3 meshes with the gear ring 4.

[0025] The operation process of this embodiment is as follows: The base platform 1 is placed at the dust source of mining. When in use, the drive motor drives the drive gear 3 to rotate. The drive gear 3 drives the gear ring 4 to rotate. The rotation of the gear ring 4 drives the conical gear disk 5 to rotate. Since the conical gear disk 5 and the conical gear 7 mesh with each other, as the conical gear disk 5 rotates, multiple conical gears 7 rotate in the same direction around the rotating shaft 6. The rotation of the rotating shaft 6 drives the fan blades 8 to rotate. The fan blades 8 are distributed around the circumference of the base platform 1, and the axis of each rotating shaft 6 is perpendicular to the axis of the base platform 1. The rotation of the fan blades 8 creates negative pressure, which guides the external dust from the outside to the inside of the base platform 1. During the dust removal process, the negative pressure created by the rotation of multiple sets of fan blades 8 guides the air with dust on the outside of the base platform 1 to the inside of the base platform 1, thereby completing the dust collection and increasing the dust treatment area of ​​the device.

[0026] Dust-laden air enters the base 1 from the outside. The rotating fan blades 8 cause the dust to pass through the inlet of the guide shroud 12 and then exit through its outlet. The water supply pipe 9 is connected to a water source, and a water pump continuously pumps water from the source into the pipe 9. The water flows through the pipe 9 into the ring pipe 10, then into the water supply ring 11, and is sprayed out through the atomizing nozzle 13. The atomizing nozzle 13 is positioned perpendicular to the axis of the guide shroud 12 and on the other side of the fan blades 8. When dust is attracted... After the negative pressure generated by the rotation of the fan blade 8, the dust flows from the inlet of the guide shroud 12 toward the outlet. Water is sprayed onto the passing dust through the atomizing nozzle 13, causing water droplets to adhere to the dust. This atomizing water spray increases the weight of the dust flowing through the guide shroud 12, causing it to settle. During operation, the device continuously draws the dust outside the base 1 to the outlet of the guide shroud 12 and sprays the flowing dust to suppress dust. This effectively suppresses dust generated during mining operations.

[0027] Example 2

[0028] Although the atomizing nozzle 13 can spray and suppress dust, the dust particles that come into contact with the water mist remain at the center of the base platform 1. Therefore, although dust is suppressed by spraying, it is not collected. For this reason, please refer to... Figure 1-2 Based on the first specific embodiment, a gathering bucket 14 is fixedly connected to the base 1, a filter plate is fixedly connected to the gathering bucket 14, and a flexible hose 15 is connected to the gathering bucket 14, with an external fan connected to the flexible hose 15.

[0029] The operation process of this embodiment is as follows: After the dust is sprayed to reduce dust, it gathers at the axial position of the base platform 1. By connecting the fan to the hose 15, the gathering bucket 14 is located at the axial position of the base platform 1. The fan creates negative pressure and draws in the air in this area to collect the gathered dust. The collected dust is stored in the gathering bucket 14. The gathered dust and air can be drawn into the gathering bucket 14, which further improves the dust removal effect of the device.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
