Description

Technical Field

[0001] This utility model relates to the technical field of coal cleaning and dust removal devices, specifically to a coal cleaning and dust removal device. Background Technology

[0002] The main sources of coal mine dust are the mining, transportation, and screening processes. Coal mine dust is abundant and not only harms miners but also impacts the daily lives of residents in the surrounding areas. When the dust concentration in the air reaches a certain threshold, it may explode upon contact with an open flame or heat source, causing significant damage to the coal mine and surrounding areas, and potentially leading to serious safety accidents. Therefore, effective dust control during coal mining and transportation is crucial to ensure safe production, protect the safety of surrounding residents, and reduce the incidence of various dangerous accidents.

[0003] To reduce coal ash generated during mining and transportation, existing technologies employ spray atomization for dust suppression and removal, aiming to reduce dust pollution of the surrounding environment and ensure coal mining safety. For example, the public announcement (CN202704478U) discloses a water spray dust suppression device and coal conveying equipment using the water spray dust suppression device. However, a single nozzle is used in each dust suppression area, resulting in poor dust suppression through spray atomization. Furthermore, the single nozzle has a single spray direction, which cannot adapt to the dust suppression of coal mining and transportation under different geological conditions.

[0004] Therefore, a coal cleaning and dust removal device is needed. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention provides a coal cleaning and dust removal device, which aims to solve the technical problems mentioned above.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a coal cleaning and dust removal device, including a belt conveyor, with drive motors evenly distributed on both sides of the conveying direction of the belt conveyor, a key shaft installed between the drive motor and the bearing seat, a connecting sleeve evenly distributed on the key shaft, a support plate set on the upper part of the connecting sleeve, and fixed plug-in seats symmetrically arranged on the upper part of the support plate, with plug rods installed on the fixed plug-in seats by spring locks, the top ends of the two plug rods connected by a nozzle mounting base, nozzles evenly distributed on the front surface of the nozzle mounting base facing the belt conveyor, and a conduit connected to the back surface of the nozzle mounting base.

[0007] Preferably, the nozzle mounting base is designed with an arc-shaped plate structure.

[0008] Preferably, four rows of nozzles are evenly distributed on the front surface of the nozzle mounting base, with three nozzles in each row.

[0009] Preferably, two sets of coupling sleeves are evenly distributed on the key shaft, and a nozzle mounting base is installed on each set of coupling sleeves.

[0010] Preferably, the key shafts on both sides of the belt conveyor are distributed in an alternating structure.

[0011] Preferably, the key shafts on both sides of the belt conveyor are arranged horizontally and symmetrically.

[0012] In summary, this utility model provides a coal cleaning and dust removal device. This utility model patent uses the rotation of a belt conveyor to drive the rotation of the connecting sleeve, so as to adjust the angle of the insert rod 1 and the nozzle mounting base 2 upward or downward. The upward angle is used to achieve the effect of rapid dust reduction in coal mines, and the downward adjustment is used to achieve a higher dust concentration and rapid downward spraying to quickly achieve the dust reduction effect.

[0013] In order to achieve coal dust suppression under different geological conditions, when the coal quality is poor and the dust volume is large, the key shafts on both sides of the belt conveyor are arranged horizontally and symmetrically to increase the number of nozzles used and improve the dust suppression effect.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 As shown:

[0018] This utility model is a coal cleaning and dust removal device, designed to address the shortcomings of existing coal spraying technology, such as poor dust removal efficiency and the limitation of single-direction spraying, which makes it unsuitable for coal mine dust removal under various geological conditions. The device utilizes the following equipment: a Tongli coal mine belt conveyor, a ZP-12C mine dust suppression sensor, a GWSD100 / 100 coal mine temperature and humidity sensor, and a KXJ1-20 / 1140(660) explosion-proof and intrinsically safe programmable control box. The coal cleaning and dust removal device includes a belt conveyor 1. Drive motors 2 are evenly distributed on both sides of the conveying direction. A key shaft 3 is installed between the drive motor 2 and the bearing seat. A connecting sleeve 4 is evenly distributed on the key shaft 3. The upper part of the connecting sleeve 4 is set as a support plate 5. A fixed plug seat 6 is symmetrically arranged on the upper part of the support plate 5. The fixed plug seat 6 is equipped with a plug rod 11 through a spring lock 7. The top ends of the two plug rods 11 are connected through a nozzle mounting base 12. Nozzles 13 are evenly distributed on the front surface of the nozzle mounting base 12 facing the belt conveyor 1. A conduit is connected to the back surface of the nozzle mounting base 12.

[0019] The specific dust removal principle is as follows: An intelligent control box (not shown in the figure) controls the belt conveyor 1, drive motor 2, and water booster pump (not shown in the figure). Dust sensor 14 and humidity sensor 15 monitor the dust concentration and atomized humidity around the belt conveyor 1. During coal transportation, the monitoring data is transmitted to the control box, which controls the increase or decrease of the water booster pump to achieve atomized dust reduction of coal dust. When the spray humidity is high, the humidity sensor 15 monitors the data and feeds it back to the intelligent control box, which controls the water booster pump to reduce the booster pressure, thereby reducing the atomization of the nozzle 13 and lowering the humidity around the belt conveyor 1.

[0020] The spray angle of the nozzle mounting base 12 is adjustable to adapt to the coal dust concentration under different geological conditions. The angle adjustment method is as follows: drive motors 2 and key shafts 3 are distributed on both sides of the belt conveyor 1. The key shafts 3 are equipped with coupling sleeves 4. The belt conveyor 1 rotates to drive the coupling sleeves 4 to rotate, so as to adjust the angle of the insert rod 11 and the nozzle mounting base 12 upward or downward. The upward angle is used to achieve the effect of rapid dust reduction in coal mines, and the downward adjustment is used to achieve the effect of rapid downward spraying when the dust concentration is high.

[0021] In at least one embodiment, in order to increase the dust suppression spray area, the nozzle mounting base 12 of this embodiment adopts an arc-shaped plate structure to achieve dust suppression spraying in three directions: upper, middle and lower, so as to achieve a more thorough dust suppression effect.

[0022] In at least one embodiment, in order to increase the dust suppression area, four rows of nozzles 13 are evenly distributed on the front surface of the nozzle mounting base 12, with three nozzles in each row, so as to achieve dust suppression by spraying in the middle and lower three directions, thereby solving the problem of poor dust suppression effect of the single spraying method in the prior art.

[0023] In at least one embodiment, to achieve a more thorough spraying effect, two sets of connecting sleeves 4 are evenly distributed on the key shaft 3, and a nozzle mounting base 12 is installed on each set of connecting sleeves 4, so that multiple sets of nozzles 13 can simultaneously perform dust suppression and provide dust removal function.

[0024] In at least one embodiment, in order to achieve coal dust suppression under different geological conditions, when the coal quality is good and the dust emission is low, the key shafts 3 on both sides of the belt conveyor 1 are arranged in an interlaced structure to reduce the number of nozzles 13 installed while still achieving the dust suppression effect.

[0025] In at least one embodiment, in order to achieve coal dust suppression under different geological conditions, when the coal quality is poor and the amount of dust is large, the key shafts 3 on both sides of the belt conveyor 1 are arranged horizontally and symmetrically to increase the number of nozzles 13 used and improve the dust suppression effect.

[0026] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
