Description

Technical Field

[0001] This utility model belongs to the field of mining equipment, and in particular relates to a conveying device for mining. Background Technology

[0002] In the mining, mineral processing, and aggregate manufacturing industries, the material transfer link from the crusher outlet to the belt conveyor inlet is the core area for dust generation. Materials here typically exhibit characteristics of high drop, large impact force, and wide particle size distribution. When materials fall freely and impact the conveyor belt or buffer rollers, kinetic energy is converted into airflow turbulence, entraining fine particles and forming a jet-like dust cloud. In traditional single-stage chute designs, material directly impacts the bottom of the chute, causing secondary crushing and exacerbating dust generation. Furthermore, vibration issues also exist in the middle and end sections of the conveyor due to material transfer, thus also contributing to a small amount of dust. To address these problems, this application proposes a new device. Utility Model Content

[0019] like Figure 1-5 As shown, a mining conveying device includes a feeding component 1, a conveyor belt 3, a discharge corridor 4, and a negative pressure component 5. The feeding component 1 has a feeding chamber 102, and a stepped chute 101 is provided within the feeding chamber 102. Several guide plates 6 are provided along the length of both sides of the stepped chute 101. A negative pressure component 5, connecting to the feeding chamber 102, is provided through one side of the feeding component 1. The end of the stepped chute 101 connects to the input end of the conveyor belt 3, and the output end of the conveyor belt 3 connects to the discharge corridor 4. Support frames 2 are symmetrically provided on both sides of the conveyor belt 3 for support. Ore falling from the crusher outlet enters the feeding port 103, slides through the stepped chute 101 into the conveyor belt 3, and finally falls into the discharge corridor 4 to enter the next process. Dust generated by impact in the feeding chamber 102 is discharged through the negative pressure component 5. Ore dust on the conveyor belt 3 falls into the arc-shaped trough 202 through the dust collection port 301. Ore dust in the discharge corridor 4 is intercepted by spraying.

[0020] like Figure 2 As shown, the feed chamber 102 has a feed inlet 103 and a discharge outlet 104 at both ends. The feed inlet 103 is located at the top of the feed component 1, and the discharge outlet 104 is located at one end of the feed component 1. The stepped chute 101 connects the feed inlet 103 and the discharge outlet 104. Rubber curtains 7 are vertically installed on the feed inlet 103 and the discharge outlet 104. The stone material exiting the crusher outlet falls into the feed inlet 103, and then falls down the stepped chute 101 from the feed inlet 103 to the discharge outlet 104, and then into the conveyor belt 3. The two rubber curtains 7 make the space inside the feed chamber 102 relatively sealed, avoiding the diffusion of dust generated by impact. The stepped chute 101 adopts a multi-stage inclined structure, with the inclination angle gradually decreasing from top to bottom. The middle part has a horizontal section, which is used to achieve the slow descent of ore and reduce initial dust. Wear-resistant material lining plates are laid on the stepped chute 101.

[0021] The guide plate 6 includes a plate body 602 and a spring 601. The spring 601 is detachably mounted on the side wall of the feed chamber 102, and the plate body 602 is rotatably mounted on the side wall of the feed chamber 102, with the plate body 602 abutting against the spring 601. The guide plate 6 is mainly used to constrain the width of the material flow, prevent splashing, absorb impact energy, and extend the service life of the stepped chute 101. The plate body 602 and the spring 601 are not directly connected. When the material flow pushes the plate body 602 to both sides, it will naturally compress the spring 601. To prevent the spring 601 from shifting, a guide post can also be provided for the spring 601. At the same time, a slot along the length direction is provided on the plate body 602, and the guide post is slidably mounted in the slot to achieve the same effect.

[0022] like Figure 5 As shown, the negative pressure component 5 includes a connecting pipe 501, a dust collection box 502, a filter cloth 503, and a fan 504. The connecting pipe 501 connects the feed chamber 102 and the interior of the dust collection box 502. The fan 504 is detachably mounted on one side of the dust collection box 502, and the filter cloth 503 is detachably mounted on the side of the dust collection box 502 near the fan 504. The negative pressure component 5 can draw the floating dust in the feed chamber 102 into the dust collection box 502 through negative pressure. The filter cloth 503 is made of PTFE membrane material and allows gas to pass through. The floating dust is trapped in the dust collection box 502. The side wall of the dust collection box 502 has an openable opening, which can be opened to remove the deposited floating dust in the dust collection box 502 or to replace the filter cloth 503. The filter cloth 503 can be set in the dust collection box 502 by a clamping component or a pin.

[0023] like Figure 1-2As shown, a drive shaft 303 is rotatably provided through both ends of the two support frames 2. The two drive shafts 303 are respectively connected to both ends of the conveyor belt 3. The drive shafts 303 are used to drive the conveyor belt 3 to rotate. Several partition plates 302 are arranged along the length direction on the outer side of the conveyor belt 3. The partition plates 302 divide the space of the conveyor belt 3 into a grid to prevent the ore above from moving. Dust collection ports 301 are arranged along the length direction on the conveyor belt 3. The dust collection ports 301 are narrow and can allow small dust particles to pass through. The dust particles fall from the dust collection ports 301 into the arc-shaped groove 202. The inner side of the conveyor belt 3 is provided with a support roller 304. The support roller 304 is set at the bottom of the upper conveyor belt. The two ends of the support roller 304 are rotatably connected to the two support frames 2. A V-shaped plate 10 is provided on the inner side of the conveyor belt 3, and an arc-shaped groove 202 is provided in the support frame 2. A through groove 201 is provided along the length direction on the side of the two support frames 2 near the conveyor belt 3. The through groove 201 connects to the top of the arc-shaped groove 202.

A conveying pipe 203 is provided through the bottom of the support frame 2, and the conveying pipe 203 connects to the bottom of the arc-shaped groove 202. The V-shaped plate 10 is located between the upper and lower layers of the conveyor belt 3. Dust falling from the dust collection port 301 slides down from the V-shaped plate 10 to both sides into the arc-shaped groove 202. The dust in the arc-shaped groove 202 can be conveyed to the dust collection bin for other uses through the conveying pipe 203. The output end of the conveying pipe 203 can be equipped with a ventilation device to create negative pressure to suck up the dust.

[0024] like Figure 2 As shown, the discharge corridor 4 is equipped with ultrasonic dry fog nozzles 8 and active foaming agent nozzles 9, and rubber curtains 7 are vertically installed at both ends of the discharge corridor 4. The ultrasonic dry fog nozzles 8 spray liquid that comes into contact with floating dust to form larger particles that settle, while the active foaming agent nozzles 9 act directly on the ore surface to prevent dust from flying.
