Description

Technical Field

[0001] This invention relates to the field of ore processing, and more particularly to an apparatus for ore sorting and separation. Background Technology

[0002] After existing ore and rock are crushed, the ore needs to be separated from the waste rock. This is often done manually, which is not only labor-intensive and inefficient, but also prone to personal injury accidents. Even with simple sorting and separation devices, it is difficult to intelligently separate the ore and waste rock. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the purpose of this invention is to provide an ore processing and separation device for use in the field of ore processing, including an ore feeding device, a vertical speed-increasing conveyor, a horizontal conveyor, a vision-based mineral processing conveyor, a vision recognition system, and a waste separation device; the ore feeding device is located at one end of the horizontal conveyor, and the vision-based mineral processing conveyor is located at the other end of the horizontal conveyor; a vision recognition system is installed above the vision-based mineral processing conveyor, and the waste separation device is located at the outlet end of the vision-based mineral processing conveyor; Multiple sets of vertical speed-increasing conveyors are suspended above both sides of the horizontal conveyor. Each set of vertical speed-increasing conveyors has a different angle with the horizontal conveyor in the conveying direction, which increases from small to large along the conveying direction, using the speed difference to increase the spacing between the ore.

[0004] The vertical speed-increasing aligning conveyor consists of three sets. The first set of vertical speed-increasing aligning conveyors has a conveying direction angle of 20 degrees with the horizontal conveyor, while the other two sets of vertical speed-increasing aligning conveyors have a conveying direction angle of 30 degrees with the horizontal conveyor.

[0005] The visual ore sorting conveyor operates at a higher speed than the horizontal conveyor, further increasing the spacing between ore particles.

[0006] Vertical rollers are installed below the frame of the vertical speed-increasing conveyor. A drive roller and a driven roller are installed at both ends of the vertical rollers respectively. The speed-increasing belt is installed between the drive roller and the driven roller. The roller surfaces of the drive roller and the driven roller are higher than the vertical rollers to ensure that the vertical rollers do not contact the speed-increasing belt when running under no-load. When working under load, the ore squeezes the speed-increasing belt, and the speed-increasing belt contacts the surface of the vertical roller, driving the vertical roller to rotate together. The speed-increasing belt has a V-shaped belt tooth inside and a synchronous belt tooth outside, and the two are integrated into one structure.

[0007] A horizontal fixed frame is installed on the frame of the sorting and separating device, and the vertical speed-increasing and aligning conveyor is fixed between the fixed frame and the frame of the sorting and separating device by bolts.

[0008] The beneficial effects of this invention are as follows: This invention relates to a vertical speed-increasing conveyor for ore alignment, featuring a unique layout, high alignment efficiency, and strong specialization. The speed-increasing belt contains a group of vertical rollers that do not contact the belt during no-load operation. Under load, the ore compresses the belt, bringing it into contact with the vertical rollers. The speed-increasing belt drives the vertical rollers to rotate together, with the rollers bearing the pressure from the ore, thus preventing excessive wear or damage to the speed-increasing belt. The speed-increasing belt has a V-shaped belt tooth profile inside and a synchronous belt tooth profile outside, forming an integrated structure. This structure features a V-shaped belt with high transmission efficiency, a compact structure, and stable operation, free from belt tipping or shaking, exhibiting strong lateral rigidity and low vibration at high speeds. The synchronous belt tooth profile outside increases friction between the ore and the belt surface, further enhancing the alignment effect. The ore sorting and separation device is controlled by a PLC, achieving automated control of the entire device's operation, making it highly practical and automated. Attached Figure Description

[0010] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the preferred embodiments of the present invention, and not all of the embodiments.

[0011] As shown in the figure, the present invention includes an ore feeding device 1, a vertical speed-increasing conveyor 2, a horizontal conveyor 3, a vision-based mineral processing conveyor 4, a vision recognition system 5, and a waste separation device 6. The ore feeding device 1 is located at one end of the horizontal conveyor 3, and the vision-based mineral processing conveyor 4 is located at the other end of the horizontal conveyor 3. The vision recognition system 5 is located above the vision-based mineral processing conveyor 4, and the waste separation device 6 is located at the outlet end of the vision-based mineral processing conveyor 4. The invention also includes a controller, such as a PLC, which is connected to the ore feeding device 1, the vertical speed-increasing conveyor 2, the horizontal conveyor 3, the vision-based mineral processing conveyor 4, the vision recognition system 5, and the waste separation device 6.

[0012] Multiple sets of vertical speed-increasing conveyors 2 are suspended above both sides of the horizontal conveyor 3. Each set of vertical speed-increasing conveyors 2 has a different angle with the horizontal conveyor 3 in the conveying direction, which increases from small to large along the conveying direction, using the speed difference to widen the gap between the ore.

[0013] Preferably, the vertical speed-increasing and aligning conveyor 2 consists of three groups. The first group of vertical speed-increasing and aligning conveyors 2 has a conveying direction angle α of 20 degrees with the horizontal conveyor 3, while the other two groups have a conveying direction angle b of 30 degrees with the horizontal conveyor 3. This speed difference widens the gap between the ore particles, and the working surface of the conveyor belt guides and rotates the ore to correct its posture, thus aligning the ore into a longitudinal column along the conveying direction to avoid stacking. After speed-increasing and aligning, the ore is output in an orderly longitudinal column from the tail outlet, directly connecting to the vision sorting conveyor. Here, the first group is calculated starting from the group closest to the ore feeding device 1.

[0014] The visual mineral processing conveyor 4 operates at a higher speed than the horizontal conveyor 3, which can further increase the spacing between ore particles.

[0015] A vertical roller 202 is installed below the frame 201 of the vertical speed-increasing conveyor 2. A drive roller 203 and a driven roller 204 are respectively installed at both ends of the vertical roller 202. A speed-increasing belt 207 is installed between the drive roller 203 and the driven roller 204. The roller surfaces of the drive roller 203 and the driven roller 204 are higher than the vertical roller 202 to ensure that the vertical roller 202 does not contact the speed-increasing belt 207 when running under no-load. When under load, the ore squeezes the speed-increasing belt 207, and the speed-increasing belt 207 contacts the surface of the vertical roller 202, causing the speed-increasing belt 207 to drive the vertical roller 202 to rotate together. The speed-increasing belt 207 has a V-shaped combined belt tooth shape inside and a synchronous belt tooth shape on the outside, and the two are integrated into one structure.

[0016] A belt tensioning device 205 is provided at the end of the frame 201 to adjust the position of the drive roller and adjust the tension of the speed-increasing belt 207.

[0017] The drive roller 203 is driven by the motor 206.

[0018] A horizontal fixed frame 701 is provided on the frame 7 of the sorting and separating device, and the vertical speed-increasing aligning conveyor 2 is fixed between the fixed frame 701 and the frame 7 of the sorting and separating device by bolts.

[0019] The ore feeding device 1 is provided with periodic excitation force by a vibrating motor, which drives the feed trough to perform simple harmonic vibration (up and down vibration). The ore in the feed trough is subjected to the combined action of inertial force, gravity and friction. When the inertial force causes friction between the ore and the feed trough, the material is thrown forward or slides along the trough, forming a continuous and uniform ore flow.

[0020] The vertical speed-increasing aligning conveyor consists of 3 groups. The angle between the first group of vertical speed-increasing aligning conveyors and the horizontal conveyor 3 is 20° (the angle between the second and third groups is 30°). The conveyor belt of the horizontal conveyor is made of four layers of wear-resistant PVC-coated rubber, which has good wear resistance and high strength, and meets the needs of ore conveying. The belt tensioning device 205 adopts an integrated structure, which is convenient to install. Both the tensioning device bearing and the drive roller bearing use UCP type self-aligning bearings, which can realize automatic self-alignment and ensure smooth operation of the conveyor belt.

[0021] The visual mineral processing conveyor has a compact structure and a higher operating speed than the horizontal conveyor, which can further increase the spacing between ore particles. It also serves as the carrier device for the visual recognition system.

[0022] The purpose of further increasing the spacing between ore particles is to facilitate the accurate identification of ore and waste rock by the visual recognition system.

[0023] The visual recognition system can identify ore and waste rock and send recognition signals to the PLC control system.

[0024] The mineral waste separation device receives instructions from the PLC control system and uses a cylinder to push a swing plate to strike the ore, separating the ore and waste rock and sending them to different storage areas. The aforementioned ore feeding device, vertical speed-increasing conveyor, horizontal conveyor, vision-based mineral processing conveyor, vision recognition system, and mineral waste separation device together constitute the mineral processing and separation device.

[0025] The principle of this invention is: After the ore enters the feeding hopper, it is conveyed by a vibrating feeder and initially aligned. Upon reaching the horizontal conveyor belt, the ore undergoes a second alignment process via three sets of vertical speed-increasing conveyors, ultimately forming a regular column. The ore then enters the horizontal conveyor belt of the vision recognition system for acceleration, increasing the spacing between ore particles before entering the system's recognition area. After analysis and comparison, the system outputs a signal identifying either ore or waste rock. The ore then enters the waste rock separation device, where the oscillating and tapping action of cylinder-driven baffles separates the ore and waste rock into two different storage areas. This system features intelligent identification and separation of ore and waste rock, employing a touch-screen intelligent control interface to adapt to various operating conditions.
