A ferrochrome smelting slag recovery device

Abstract

This invention discloses a waste slag recycling device for ferrochrome smelting, relating to the field of ferrochrome smelting technology. It includes a base plate, with cylinders fixedly connected to the top of the base plate near both sides. A horizontal plate is fixedly connected to the top of each cylinder, and a cylinder is fixedly connected between the two horizontal plates. A handle drives an arc-shaped plate to rotate, pouring the waste slag into the cylinder. A second motor drives a cone crusher to rotate, grinding and crushing the waste slag. Small particles of the crushed waste slag pass through a filter screen and are discharged into the cylinder, while larger particles remain on top of the filter screen. The cylinder moves up and down via the horizontal plates, allowing the larger particles to continue contacting the cone crusher for further grinding and crushing. The filtered waste slag falls onto the surface of a magnetic drum, which adsorbs the iron slag within it. A first motor drives the magnetic drum to rotate, thereby expanding the magnetic drum's adsorption area for the iron slag.

Description

[0001] This invention relates to the field of ferrochrome smelting technology, specifically to a ferrochrome smelting waste slag recycling device. Background Technology

[0002] Ferrochrome is an iron alloy composed of chromium and iron, and is an important alloying additive in steelmaking. Ferrochrome is classified into high-carbon ferrochrome, medium-carbon ferrochrome, low-carbon ferrochrome, micro-carbon ferrochrome, and ultra-micro-carbon ferrochrome according to its carbon content. Waste slag is generated during the smelting process of soldering iron, and the waste slag needs to be recycled.

[0017] Working principle: When the device starts working, the handle 30 drives the arc plate 29 to flip, pouring the waste residue into the cylinder 4. The waste residue will be located at the top of the filter screen 31 and will be in contact with the surface of the cone crusher 23. The second motor 19 is started, which drives the transmission rod 20 to rotate. The transmission rod 20 drives the rotating plate 21 to rotate, which in turn drives the connecting rod 22 to rotate. The connecting rod 22 drives the cone crusher 23 to rotate, and the cone crusher 23 will grind and crush the waste residue. The crushed small particles of waste residue will pass through the filter screen 31 and be discharged into the cylinder 4, while the large particles of waste residue will remain at the top of the filter screen 31. At this time, the cylinder 2 is started, and the cylinder 2 drives the cylinder through the horizontal plate 3. As body 4 moves up and down, large particles of waste residue will continue to contact the cone crusher 23, which will grind and crush them. The filtered waste residue will fall onto the surface of the magnetic drum 6, which will adsorb the iron slag in the waste residue. The first motor 8 is started, and the first motor 8 drives the first fixed column 13 to rotate through the cross rod 9. The first fixed column 13 drives the magnetic drum 6 to rotate, which in turn drives the second fixed column 14 and the fixed disk 15 to rotate, thereby expanding the adsorption area of ​​the magnetic drum 6 for the iron slag. Non-magnetic waste residue will accumulate at the bottom of the inner cavity of the connecting frame 5. If it is necessary to discharge non-magnetic waste residue, the operator stands in front of the connecting frame 5 and rotates the connecting frame 5. The top of the connecting frame 5 opens. When the opening is rotated to the rear, the non-magnetic waste residue inside will be discharged. If it is necessary to collect and recycle the iron slag on the magnetic drum 6, the scraper 16 is flipped, the first magnet 17 and the second magnet 18 move away from each other, the scraper 16 is attached to the surface of the magnetic drum 6, and the first motor 8 controls the magnetic drum 6 to rotate. The scraper 16 will scrape the iron slag on the surface of the magnetic drum 6, thereby collecting and recycling it. The first motor 8 is detachable. The movable plate 11 is moved to the left, and the movable plate 11 drives the slider 12 to move to the left. The movable plate 11 drives the first motor 8 to move to the left through the fixed block 10, moving the cross bar 9 out of the first fixed column 13 and moving the first motor 8 upward. The first motor 8 drives the cross bar 9 to move to the left. Once the rod 9 and the fixing block 10 are moved away from the movable plate 11, they can be disassembled. If it is necessary to disassemble the filter screen 31, first rotate the threaded rod 32 to move the threaded rod 32 downward. The threaded rod 32 drives the support plate 33 to move downward, and the electric telescopic rod 35 is activated. The electric telescopic rod 35 drives the flipping plate 34 to rotate. The flipping plate 34 rotates through the hinge. The flipping plate 34 drives the threaded rod 32 and the support plate 33 to rotate, so that the filter screen 31 can be taken out from the inside of the cylinder 4. Rotate the bolt 27 to remove the bolt 27 from the cylinder 4 and the clamping plate 26. Then move the second motor 19 upward. The second motor 19 can drive the cone crusher 23 to move upward, thereby performing the disassembly work.
