Description

Technical Field

[0001] This utility model relates to the field of coal transportation technology, and more specifically to a dust suppression device for conveyor belt transport of coal blocks. Background Technology

[0002] Belt conveyor coal transport refers to a mechanized transportation method that uses continuously operating belt conveyors to efficiently transport coal from mining sites, coal storage yards, or processing points to loading points, boilers, or designated locations. Its characteristics include large capacity, long distance transport, high speed, and low cost. It can be arranged horizontally or at an incline and is widely used in coal mines, power plants, ports, and other scenarios to achieve automated coal logistics transfer.

[0003] During coal transportation, when large pieces of coal fall from the upper conveyor belt to the lower conveyor belt, the resulting impact can cause dust to spread. To suppress dust spread and collect dust, fixed dust suppression devices are usually installed on the conveyor frame. However, because these devices are fixed in position and cannot be flexibly adjusted, it is difficult to adjust them to the actual point where the coal pieces fall, resulting in poor dust suppression effect.

The dust removal component includes an anti-diffusion frame and a dust suction pipe connected to the anti-diffusion frame. The input end of the dust suction pipe is located above the conveying surface of the lower belt. The anti-diffusion frame is detachably fixed to the conveyor frame of the lower belt by bolts.

[0009] As a preferred technical solution, a connecting frame extending towards the conveyor frame of the lower belt is fixedly connected to the anti-diffusion frame. The lower belt conveyor frame has multiple linear slots distributed along the length of the conveyor frame. The connecting frame is connected and fastened to the slots by bolts.

[0010] As a preferred technical solution, the top of the conveyor frame of the lower belt is also fixedly connected with a pair of limiting plates, and the pair of limiting plates form a track that is compatible with the anti-spreading frame.

[0011] As a preferred technical solution, the dust removal component also includes a horizontal pipe connected to the suction pipe. A motor is fixedly connected inside the horizontal pipe, and the output end of the motor is connected to the dust removal fan blades, which can drive the dust removal fan blades to rotate around its axis.

[0012] As a preferred technical solution, the dust removal component also includes a filter box, and the horizontal pipe is connected to the external pipeline through the filter box.

[0013] As a preferred technical solution, a material drop plate for guiding coal blocks is fixedly installed between the two fixed blocks, and a stop block for limiting the buffer plate is fixedly installed on the surface of the fixed block.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See Figure 1A dust suppression device for conveying coal blocks by belt includes a conveying mechanism 100 and a dust suppression mechanism 200. The dust suppression mechanism 200 is detachably and fixedly connected to the conveying surface of the conveying mechanism 100. In this embodiment, the dust removal component 210 of the dust suppression mechanism 200 is detachably and fixedly connected to the conveying surface of the conveying mechanism 100. The conveying mechanism 100 includes an upper belt 110 and a lower belt 120. The upper belt 110 is located upstream of the lower belt 120, and the conveying surface of the upper belt 110 is above the conveying surface of the lower belt 120. Both the upper belt 110 and the lower belt 120 are equipped with conveyors. The dust removal component 210 is slidably connected to the top of the lower belt 120. In this embodiment, the dust removal component 210 is slidably connected to the top of the conveyor frame of the lower belt 120. The dust removal component 210 includes an anti-diffusion frame 211 and a dust suction pipe 213 communicating with the anti-diffusion frame 211. The input end of the dust suction pipe 213 is located above the conveying surface of the lower belt 120. The anti-diffusion frame 211 is detachably fixed to the conveyor frame of the lower belt 120 by bolts, so that the position of the dust suction pipe 213 of the dust removal component 210 can be adjusted according to the landing point of the coal blocks on the lower belt 120 in different conveying sections.

[0028] The anti-diffusion frame 211 is provided with a position adjustment component 220, which includes a connecting frame 221, a wing bolt 222, a slot 223, and a limiting plate 224. The connecting frame 221 extending towards the conveyor frame of the lower belt 120 is fixedly connected to the anti-diffusion frame 211. The connecting frame 221 has an L-shaped structure. Its horizontal section extends along the width direction of the conveying surface of the lower belt 120 and is fixed perpendicularly to the conveyor frame of the lower belt 120. Its vertical section extends downward along the height direction of the conveyor frame of the lower belt 120. Multiple linear slots 223 are provided on the conveyor frame of the lower belt 120 and distributed along the length direction of the conveyor frame of the lower belt 120. The connecting frame 221 is connected and fastened to the slots 223 by bolts. In this example, the bolts can be wing bolts 222.

[0029] The top of the conveyor frame of the lower belt 120 is also fixedly connected with a pair of limiting plates 224. The limiting plates 224 can also be set on the side wall of the top of the conveyor frame. The pair of limiting plates 224 form a track that is compatible with the anti-diffusion frame 211. The anti-diffusion frame 211 is a portal structure that spans the conveyor frame of the lower belt 120. In this embodiment, two pairs of limiting plates 224 are provided, and each pair of limiting plates 224 includes two oppositely arranged limiting plates 224.

[0030] The suction pipe 213 is vertically arranged. In this embodiment, three suction pipes 213 are arranged linearly along the width direction of the lower belt 120, perpendicular to the conveying surface of the lower belt 120, so as to ensure that the suction area can cover the conveying surface of the lower belt 120. Of course, other numbers of suction pipes 213 can also be set, such as two, four, five, etc., and the number is not limited to this.

[0031] See Figure 1 , Figure 4 A buffer component is also provided between the conveying surfaces of the lower belt 120 and the upper belt 110. The buffer component can guide and buffer the coal blocks, thereby reducing the impact when the coal blocks fall from the conveying surface of the upper belt 110 to the conveying surface of the lower belt 120 and reducing dust. The buffer component includes a guide plate 230 and a buffer plate 233. The guide plate 230 is inclined from the conveying surface of the upper belt 110 toward the conveying surface of the lower belt 120 to guide the coal blocks. At least one fixing block 231 is fixedly connected to the conveyor frame of the upper belt 110. In this embodiment, two fixing blocks 231 are fixedly connected to the front end of the conveyor frame of the upper belt 110. The two fixing blocks 231 are fixedly connected to both ends of the guide plate 230, thereby providing connection support for the guide plate 230.

[0032] Rotating rods 232 are rotatably connected to two fixed blocks 231. Support plates are fixedly connected to the ends of the rotating rods 232 that pass through the fixed blocks 231. In this embodiment, the two ends of the rotating rods 232 pass through the two fixed blocks 231 respectively, so a support plate is provided at each end of the rotating rods 232. A torsion spring 234 is provided between a support plate and a fixed block 231. The torsion spring 234 is used to provide counterclockwise torque to the rotating rods 232. A buffer plate 233 is fixedly connected to the rotating rods 232. The buffer plate 233 is located downstream of the fixed blocks 231. When the coal block falls to the top of the buffer plate 233, it can overcome or partially overcome the torque of the torsion spring 234, driving the buffer plate 233 and the rotating rod 232 to rotate slightly counterclockwise, thereby buffering the coal block.

[0033] The guide plate 230 and the buffer plate 233 can be arranged continuously or discontinuously. When the guide plate 230 and the buffer plate 233 are arranged continuously, in order to allow the buffer plate 233 to rotate, the end of the guide plate 230 connected to the rotating rod 232 is formed with a spherical groove, and the end size of the buffer plate 233 is the same as the diameter of the rotating rod 232.

[0034] When the guide plate 230 and the buffer plate 233 are discontinuously arranged, a gap is left between the guide plate 230 and the buffer plate 233. The bottom of the guide plate 230 and the top of the buffer plate 233 are connected by a rubber belt to cover the gap, thereby preventing coal blocks from falling into the gap. In order to improve the buffering and dust suppression effect, the tilt angle of the guide plate 230 is smaller than the tilt angle of the buffer plate 233. This tilt angle is the angle between the guide plate 230 and the vertical plane of the anti-diffusion frame 211. Of course, the tilt angle of the guide plate 230 can also be set to be greater than the tilt angle of the buffer plate 233 according to the size of the coal block and the height difference between the upper belt 110 and the lower belt 120. A stop block 235 is provided at the opposite end of the two fixed blocks 231. The stop block 235 is used to limit the buffer plate 233.

[0035] See Figure 1 , Figure 3 The dust removal component 210 also includes a horizontal pipe 212 connected to the suction pipe 213 and a filter box 214. The horizontal pipe 212 is connected to an external pipeline through the filter box 214. A motor 215 is fixedly connected inside the horizontal pipe 212. The motor 215 can be a commercially available dual-shaft motor. The motor 215 is fixed to the top inner wall of the middle part of the horizontal pipe 212. The output end of the motor 215 is connected to a dust removal fan blade 216. The output end of the motor 215 can drive the dust removal fan blade 216 to rotate around its axis, which generates negative pressure inside the horizontal pipe 212, improving the dust collection effect. The air is filtered through the filter box 214, improving the dust suppression effect.
