Description

Technical Field

[0001] This invention belongs to the field of iron and steel smelting technology, and specifically relates to a treatment device and method for iron and steel smelting waste slag. Background Technology

[0002] Modern ironmaking mostly uses blast furnaces, while steelmaking mainly uses pig iron produced in blast furnaces, sponge iron produced by direct reduction ironmaking, and scrap steel as raw materials to produce steel using different methods. During the iron and steel smelting process, a large amount of waste slag is generated, which contains iron metal blocks and has a certain recycling value. When screening ferrous metal blocks in waste residue, the waste residue usually needs to be crushed. Current technology typically uses magnetic attraction during waste residue transfer to screen the ferrous metal blocks. However, when a large number of ferrous metal blocks are simultaneously attracted to the magnetic attraction components, it can cause blockages in the waste residue transfer process, resulting in a large accumulation of waste residue on the magnetic attraction. When collecting the magnetically attracted ferrous metal blocks, other waste residue may mix in, affecting subsequent processing and reducing work efficiency. Furthermore, the ferrous metal blocks in the waste residue vary in size. After collection, to facilitate subsequent processing, different sizes of ferrous metal blocks need to be processed differently, such as crushing larger blocks into smaller ones, requiring further screening, which also reduces work efficiency.

[0012] A method for treating waste slag from iron and steel smelting, using the aforementioned waste slag treatment equipment, includes the following steps; When processing steel smelting waste slag, the waste slag is fed into the waste slag treatment box. The coarse crusher performs preliminary crushing of the waste slag. The transfer conveyor belt transfers the pre-crushed waste slag to the vibrating screen plate. The vibrating screen plate vibrates and screens out the smaller waste slag pieces, which fall onto the discharge conveyor belt. The waste slag that does not pass the screening slides into the transfer trough. The rotating magnetic separation plate magnetically attracts the iron metal blocks in the waste slag in the transfer trough. As the magnetic separation plate rotates, the waste slag that is not magnetically attracted falls into the fine crusher during the transfer process. When there are only magnetically attracted iron metal blocks in the transfer trough, the discharge pusher plate moves to push the iron metal blocks out of the transfer trough. The fine crusher further crushes the initially crushed waste slag blocks. After being crushed again, the waste slag blocks fall onto the discharge conveyor belt. The magnetic separation conveyor belt can magnetically attract the iron metal blocks of the waste slag being transported on the discharge conveyor belt. The cleaning scraper scrapes the iron metal blocks adsorbed on the top surface of the magnetic separation conveyor belt into the collection box. The moving push plate moves to push the iron metal blocks out of the collection box. The waste slag blocks that are not magnetically attracted by the magnetic separation conveyor belt are transported out by the discharge conveyor belt.

[0013] Compared with the prior art, the present invention provides a treatment device and method for steel smelting waste slag, which has the following beneficial effects: 1. Waste residue is fed into the waste residue treatment box. The coarse crusher performs preliminary crushing of the waste residue. The transfer conveyor belt transfers the pre-crushed waste residue to the vibrating screen plate. The vibrating screen plate vibrates, screening out smaller waste residue pieces, which fall onto the discharge conveyor belt. Waste residue that does not pass the screening slides into the transfer trough. The rotating magnetic separator magnetically attracts the iron metal blocks in the waste residue in the transfer trough. As the magnetic separator rotates, the waste residue that is not magnetically attracted falls into the fine crusher during the transfer process. When there are only magnetically attracted iron metal blocks in the transfer trough, the discharge push plate moves to push the iron metal blocks out of the transfer trough. Magnetic attraction sorting is used when coarsely crushed waste residue is transferred in batches to avoid the accumulation of large iron metal blocks that block the transfer of waste residue when a large amount of waste residue is magnetically attracted at the same time. It also prevents other waste residue from being discharged together when iron metal blocks are removed, which would affect the subsequent processing of iron metal blocks and reduce work efficiency.

[0014] 2. The fine crusher further crushes the initially crushed waste slag. The crushed waste slag falls onto the discharge conveyor belt, where the magnetic separation conveyor belt magnetically attracts the ferrous metal blocks in the waste slag being transported. The cleaning scraper scrapes the ferrous metal blocks adsorbed on the top surface of the magnetic separation conveyor belt into the collection box. The moving push plate pushes the ferrous metal blocks out of the collection box. Waste slag blocks not magnetically attracted by the magnetic separation conveyor belt are transported out by the discharge conveyor belt. The finely crushed waste slag is magnetically attracted again to magnetically separate smaller ferrous metal blocks. This equipment magnetically separates ferrous metal blocks of different sizes in the waste slag, reducing subsequent screening processes and improving work efficiency.

[0015] 3. The fine crusher further crushes the initially crushed waste slag. The crushed waste slag falls onto the discharge conveyor belt, which moves the waste slag. The cleaning motor drives the magnetic separation conveyor belt to rotate, magnetically attracting the ferrous metal blocks of the waste slag being transported on the discharge conveyor belt. The cleaning scraper scrapes off the ferrous metal blocks adsorbed on the top surface of the magnetic separation conveyor belt. The rotating cleaning brush sweeps the ferrous metal blocks on the cleaning scraper into the collection box, preventing the accumulation of too many ferrous metal blocks on the cleaning scraper, which would affect subsequent scraping and discharge operations.

The transfer conveyor belt 202 can transfer the coarsely crushed waste residue to the vibrating screen plate 203. The vibrating screen plate 203 can vibrate to screen the waste residue. The rotating magnetic separation plate 204 has a transfer trough 206. Waste residue that does not pass the screening enters the transfer trough 206. The rotating magnetic separation plate 204 magnetically attracts the iron metal blocks in the waste residue. The rotating magnetic separation plate 204 can rotate to transfer the waste residue that is not magnetically attracted. The discharge push plate 205 can push the iron metal blocks attracted by the rotating magnetic separation plate 204 out of the transfer trough 206. The fine processing component 3 includes a fine crusher 301, a discharge conveyor belt 302, a magnetic separation conveyor belt 303, a collection box 304, a cleaning scraper 305, and a moving pusher plate 306.

The discharge conveyor belt 302 discharges and transports the finely crushed waste slag and the waste slag screened by the vibrating screen plate 203. The magnetic separation conveyor belt 303 can magnetically attract the iron metal blocks in the waste slag transported by the discharge conveyor belt 302. The cleaning scraper 305 can scrape the iron metal blocks attracted by the magnetic separation conveyor belt 303 into the collection box 304. The moving push plate 306 can push out the iron metal blocks in the collection box 304. In operation, when processing steel smelting waste slag, the waste slag is fed into the waste slag treatment box 1. The coarse crusher 201 performs preliminary crushing of the waste slag. The transfer conveyor belt 202 transfers the pre-crushed waste slag to the vibrating screen plate 203. The vibrating screen plate 203 vibrates, screening out smaller waste slag pieces, which fall onto the discharge conveyor belt 302. Waste slag that does not pass the screening slides into the transfer trough 206. The rotating magnetic separation plate 204 magnetically attracts the ferrous metal blocks in the waste slag in the transfer trough 206. As 204 rotates, the waste residue not magnetically attracted falls into the fine crusher 301 during the transfer process. When there are only magnetically attracted iron metal blocks in the transfer trough 206, the discharge push plate 205 moves to push the iron metal blocks out of the transfer trough 206. Magnetic attraction sorting is performed when the coarsely crushed waste residue is transferred in batches to avoid a large number of large iron metal blocks piling up together and blocking the transfer of waste residue when a large amount of waste residue is magnetically sorted at the same time. It also avoids other waste residue being discharged together when the iron metal blocks are removed, which would affect the subsequent processing of iron metal blocks and reduce work efficiency. The fine crusher 301 further crushes the initially crushed waste slag. The crushed waste slag falls onto the discharge conveyor belt 302. The magnetic separation conveyor belt 303 magnetically attracts the ferrous metal blocks of the waste slag being transported on the discharge conveyor belt 302. The cleaning scraper 305 scrapes the ferrous metal blocks adsorbed on the top surface of the magnetic separation conveyor belt 303 into the collection box 304. The moving pusher 306 moves to push the ferrous metal blocks out of the collection box 304. The waste slag blocks that are not magnetically attracted by the magnetic separation conveyor belt 303 are transported out by the discharge conveyor belt 302. The finely crushed waste slag is magnetically attracted again to magnetically separate the smaller ferrous metal blocks. This equipment performs magnetic separation on ferrous metal blocks of different sizes in the waste slag, reducing the subsequent screening process and improving work efficiency.

[0031] A method for treating waste slag from iron and steel smelting, using the aforementioned waste slag treatment equipment, includes the following steps; When processing steel smelting waste slag, the waste slag is fed into the waste slag treatment box 1. The coarse crusher 201 performs preliminary crushing of the waste slag. The transfer conveyor belt 202 transfers the pre-crushed waste slag to the vibrating screen plate 203. The vibrating screen plate 203 vibrates, screening out smaller waste slag pieces. The smaller waste slag pieces fall onto the discharge conveyor belt 302. The waste slag that does not pass the screening slides into the transfer trough 206. The rotating magnetic separation plate 204 magnetically attracts the iron metal pieces in the waste slag in the transfer trough 206. As the magnetic separation plate 204 rotates, the waste slag that is not magnetically attracted falls into the fine crusher 301 during the transfer process. When there are only magnetically attracted iron metal pieces in the transfer trough 206, the discharge push plate 205 moves to push the iron metal pieces out of the transfer trough 206. The fine crusher 301 further crushes the initially crushed waste slag blocks. After being crushed again, the waste slag blocks fall onto the discharge conveyor belt 302. The magnetic separation conveyor belt 303 can magnetically attract the iron metal blocks of the waste slag being transported on the discharge conveyor belt 302. The cleaning scraper 305 scrapes the iron metal blocks adsorbed on the top surface of the magnetic separation conveyor belt 303 into the collection box 304. The moving pusher 306 moves to push out the iron metal blocks in the collection box 304. The waste slag blocks that are not magnetically attracted by the magnetic separation conveyor belt 303 are transported out by the discharge conveyor belt 302.
