Description

Technical Field

[0001] The invention belongs to the technical field of raw coal and gangue separation, and particularly relates to a raw coal and gangue separation system with a heating mechanism. Background Art

[0002] Coal preparation is a crucial step in the coal production process. Excessive gangue mixed into the raw coal can degrade coal quality. Through coal preparation, different qualities of coal can be obtained, leading to comprehensive utilization of the coal. Currently, traditional coal preparation methods include manual sorting, wet separation, and X-ray separation. Wet separation is further divided into heavy medium separation and jigging.

[0003] Manual sorting methods have drawbacks such as high labor intensity, poor working environment, and low sorting efficiency. While heavy medium coal preparation methods offer high sorting efficiency and ease of large-scale coal removal, they place high demands on the performance of materials used in equipment such as pipes and chutes. While jigging coal preparation methods offer a simple process flow and high processing capacity, the equipment used occupies a large area of ​​the main plant, requiring high capital investment. Because both heavy medium and jigging coal preparation methods are wet separation methods, they require a large amount of water and can also cause water pollution. While X-ray coal preparation methods offer simple installation and a small size, their sorting capacity is limited, and X-rays can be harmful to the human body.

[0055] Additionally, the present invention provides a method for using a raw coal and gangue separation system with a heating mechanism, comprising the following steps:

[0056] 1) First, start the two vibration motors 404 so that the two vibration motors 404 drive the first screen plate 407 and the second screen plate 408 to start vibrating at the same time. At this time, the material is added through the feed box 402, the first screen plate 407 screens the large-sized raw coal and coal gangue, and the small-sized raw coal and coal gangue are screened by the second screen plate 408. The remaining coal slag passes through the second screen plate 408 and is discharged through the discharge box 409 and transported by the first conveyor belt 2 for subsequent processing;

[0057] 2) Start the two fan boxes 502 to make the two fan boxes 502 run simultaneously. Through the arrangement of the two air outlet pipes 503 and the two air inlet pipes 501, the two fan boxes 502 can extract the air mixed with smoke and dust from the sub-screening box 401 and transport it to the inside of the filter box 504. After being filtered by the two filter screens 505, the air is discharged through the exhaust pipe 508. Further, through the arrangement of the fixing plate 507 and the pulling block 506 and the arrangement of the slots, the limiting grooves and the limiting blocks, the two filter screens 505 can be pulled out of the interior of the filter box 504 by pulling the two pulling blocks 506, which is convenient for the staff to replace the filter screens 505 without stopping the machine.

[0058] 3) The power supply box 603 can be used to power the two heating boxes 605 so that the two heating tubes 606 can electrically heat the raw coal and the gangue, allowing the raw coal and the gangue to absorb heat simultaneously, facilitating the subsequent scanning process;

[0059] 4) Start the dual-axis motor 704 so that the dual-axis motor 704 drives the two rotating rods 705 to rotate, further drives the two driving gears 706 to rotate, and at the same time drives the two driven gears 707 to rotate. The rotation of the two driven gears 707 drives the two screws 708 to rotate, and then through the setting of the first thread groove, the first slide groove, the first slider, and the first moving groove, the two first moving blocks 709 can move up and down following the two screws 708, and finally drive the two first infrared scanning boxes 711 to move up and down, so as to simultaneously perform infrared scanning on the raw coal and coal gangue on the second conveyor belt 10 and the third conveyor belt 11, so as to facilitate thermal imaging.

[0060] 5) Start the two transmission motors 804 to make them run, and the threaded shaft 805 is driven to rotate by the rotation of the transmission motor 804. Further, due to the setting of the second threaded groove, the second slide groove, the second movable groove, and the second slider, the second movable block 806 can move left and right following the rotation of the threaded shaft 805. The left and right movement of the second movable block 806 drives the second connecting block 809 to move, further drives the two mounting plates 810 to move, and drives the two cylinder boxes 811 to move at the same time. When sorting needs to start, the electric box 807 drives the electric telescopic rod 808 to extend and retract, and then the cylinder box 811 drives the pneumatic rod 812 to move, and the movement of the pneumatic rod 812 drives the clamping plate 813 to move, thereby forming a clamping, and the coal gangue of different sizes is sorted.

[0061] In summary, the raw coal and gangue sorting system with a heating mechanism, by setting up a screening mechanism 4, enables the screening equipment to have multiple types of screening functions, and can effectively screen two kinds of raw coal and gangue and coal slag of different sizes. After the coal slag is screened out, it is transported separately for subsequent processing. A filtering mechanism 5 is further set up, which can strongly adsorb a large amount of smoke and dust generated when screening inside the screening box 401, and filter the adsorbed smoke and dust at the same time. The filtered air is discharged again, and the two filter plates 505 have the function of convenient replacement, so that the staff can quickly replace them. A heating mechanism 6 is further set up, which can quickly heat the raw coal and gangue after preliminary screening, so that the raw coal and gangue absorb heat at the same time. Since the raw coal and gangue have different heat absorption degrees, In this way, the gangue absorbs less heat, which makes it easier to distinguish them later. An infrared scanning mechanism 7 is further provided to scan the raw coal and gangue that have absorbed heat in all directions. Thermal imaging of the raw coal and gangue is performed by the infrared scanning equipment. At this time, the raw coal that absorbs more heat will appear dark hole color, and the gangue that absorbs less heat will appear light red. At the same time, by moving the two first infrared scanning boxes 711 up and down, two layers of raw coal and gangue of different sizes can be effectively scanned at the same time. Further, a sorting mechanism 8 is provided to enable the raw coal and gangue to be sorted instead of manually after infrared thermal imaging. The staff can quickly sort the light red gangue on the thermal imaging through the operating mechanism, and the sorted gangue is transported respectively through the fourth conveyor belt 12 and the fifth conveyor belt 13.

[0062] Furthermore, by setting up a screening mechanism 4, a filtering mechanism 5, a heating mechanism 6, an infrared scanning mechanism 7, and a sorting mechanism 8, the screening equipment has a more comprehensive screening function, and can perform screening according to different needs. At the same time, in the screening process, it avoids the need to use a large amount of water resources and energy in traditional screening methods, effectively saving water resources and other energy consumption, and also absorbs and filters the dust and smoke generated during screening, effectively reducing environmental pollution. Through infrared thermal imaging technology, it replaces traditional X-ray and other screening methods, which not only protects workers from radiation damage, but also allows for accurate identification. Finally, the setting of the sorting mechanism 8 can effectively replace manual sorting, avoids manual sorting on site, effectively protects workers, and also reduces the cost of labor and production costs. Compared with traditional sorting equipment, it is more practical and has better use effect.
