Description

Technical Field

[0001] The present invention relates to the technical field of foam slag recovery, and specifically to an efficient foam slag separation and extraction device for a converter. Background Technique

[0002] Foam slag refers to the situation during the blowing process where the total volume of small bubbles dispersed in the molten slag exceeds the volume of the molten slag itself. The molten slag becomes a thin film that wraps and separates the bubbles, causing the molten slag to foam and expand, forming foam slag. A converter generally refers to a tilting cylindrical oxygen-blowing steelmaking vessel with a cylindrical furnace body mounted on a horizontal axle and capable of rotation. After converter steelmaking is completed, the foam slag contained therein needs to be recovered and smelted.

[0003] However, during the current foam slag recovery, due to the relatively simple treatment method, a large amount of non-usable substances are mixed in the recovered materials, resulting in the need to consume a lot of time and materials to remove them during smelting. Moreover, the input recovered materials are not refined, resulting in too large raw materials and the inability to quickly heat up and smelt inside, affecting the smelting speed.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is scientific and reasonable, and it is safe and convenient to use:

[0025] 1. A combined screening component is provided. The impact hydraulic cylinder and the impact crushing plate cooperate to fix the treatment tank, and the rolling hydraulic cylinder and the rolling block cooperate to fix the operation tank to crush and refine the foam slag. Then, the magnetic adsorption fixing plate and the separation fan are used to separate and screen the crushed slag. By screening, the recyclable crushed slag is retained, reducing the overall content of the crushed slag, which facilitates subsequent treatment. Moreover, the crushed slag is refined to reduce the space occupied by the crushed slag and facilitate the transportation and movement of the crushed slag. The ball mill cylinder drives the crushed slag to rotate continuously to further refine the crushed slag, and through left and right swinging, it cooperates with the magnetic adsorption separation plate and the treatment fan to screen the crushed slag again, so as to fully process the foam slag and treat the non-recyclable crushed slag. Through multiple operations carried out simultaneously and through step-by-step crushing and refinement, while cooperating with multiple-step screening carried out simultaneously, it enables the full treatment of the crushed slag during the recycling of the crushed slag, avoiding the consumption of excessive energy and materials during subsequent smelting due to the mixing of a large amount of useless impurities. And through refinement treatment, it is convenient for rapid melting during subsequent smelting, thus accelerating the smelting speed and reducing the operation cost of smelting;

[0026] The feeding speed is controlled by the limiting fixed valve and the feeding storage box. The treatment electric push rod drives the treatment moving pipe to slide along the discharge fixed pipe, so that when discharging is required, the feeding time and the feeding amount can be controlled according to the actual operation situation, avoiding the occurrence of incomplete treatment due to material overlap. At the same time, the cleaning scraper, the discharge electric push rod and the discharge operation plate are used to clean and discharge during the treatment, and the materials are discharged centrally, avoiding the accumulation of a large amount of materials at the treatment position and affecting the production efficiency, thus ensuring the stability and speed of production;

[0027] The remaining hard foam slag is discharged through the linkage electric push rod and the blocking sliding block, and the magnetic adsorption separation mesh box is finally screened for the foam slag by the screening motor and the screening spring, so that the effective foam slag can be fully recycled during the recycling, reducing the loss rate and ensuring the quality and effect of the recycling.

[0028] 2. An outlet transportation component is provided. The discharge hydraulic cylinder drives the discharge fitting plate, and the discharge electric push rod drives the discharge fitting plate to push the recycled materials in the treatment fixed barrel and the magnetic adsorption separation mesh box into the storage concentration box. The lifting electric slide rail drives the support fixing plate, the placement linkage plate and the storage concentration box to lift, so that rapid operation can be carried out during collection. The discharge motor drives the placement linkage plate to rotate, so as to put the recycled materials into the centralized fixed hopper, enabling rapid operation during recycling and putting the recycled materials into the next-stage treatment position, thus realizing continuous linkage operation. The flow-limiting valve controls the discharge of the recycled materials in the centralized fixed hopper and the discharge of the coke powder raw materials in the storage dispersion barrel, so as to mix the recycled materials and the coke powder, enabling rapid completion of the mixing operation during treatment and facilitating subsequent smelting operations.

[0029] 3. A dispersion blowing component is provided. Oxygen is injected into the dispersion combination cylinder through an auxiliary blower, an air inlet box, and an auxiliary pipe. At the same time, the mixture is pushed towards the position of the injection fixed pipe. The flow-blocking electric push rod drives the flow-blocking closing plate to move and open the injection fixed pipe or the direct blowing pipe. The raw materials are sprayed into the smelting electric furnace through the U-shaped injection fixed pipe, and oxygen is blown into the interior through the direct blowing pipe, so that the raw materials can be fully dispersed and melted during smelting, thereby avoiding the accumulation of raw materials from affecting the melting speed and accelerating the smelting speed. Then, auxiliary materials are injected through the auxiliary pipe and melted in cooperation with the recycled materials, thereby realizing the blowing and recycling of the raw materials.

[0030] In summary, through the mutual cooperation of the combined screening component and the discharging and transporting component, the recycled materials can be quickly recycled after screening and mixed with auxiliary materials such as coke, which is convenient for subsequent smelting and recycling. Through the mutual cooperation of the discharging and transporting component and the dispersion blowing component, the materials can be quickly mixed during smelting, and refined and dispersed by means of air intake, so that the mixture can be evenly distributed during smelting, accelerating the smelting speed and avoiding the situation where the temperature drops due to the accumulation at a single position, which affects the smelting speed and quality. Through the mutual cooperation of multiple components, the full recycling and utilization of the foam slag are ensured, and the waste rate of iron is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] The working principle and usage process of the present invention: After the converter steelmaking is completed, the slag in the converter is discharged. The slag contains foamed slag. Since the foamed slag generally contains iron compounds, the foamed slag needs to be recycled and smelted. The staff puts the recycled foamed slag into the inner side of the fixed treatment tank 201 through the feeding fixed hopper 202. The lower pressing electric push rod 208 drives the blocking impact plate 209 to press down and embed into the inner side of the fixed treatment tank 201. The impact hydraulic cylinder 203 and the impact crushing plate 204 drive the foamed slag to move and impact and fit to the side end of the blocking impact plate 209. Through the extrusion force provided by the impact hydraulic cylinder 203 and the impact crushing plate 204, and with the limit and block of the blocking impact plate 209, the large pieces of foamed slag are extruded and crushed into small pieces of foamed slag, so as to refine the foamed slag. After the refinement is completed, the lower pressing electric push rod 208 drives the blocking impact plate 209 to rise, and then the impact hydraulic cylinder 203 drives the impact crushing plate 204 to push the refined foamed slag into the inner side of the feeding storage box 205, so as to realize rapid discharging and continuous treatment of the foamed slag.

[0064] After the foamed slag enters the blanking storage tank 205, the blanking of the foamed slag is controlled by the limiting fixed valve 206, so that the foamed slag enters the inside of the fixed operation tank 207. The lower piezoelectric push rod 208 drives the blocking impact plate 209 to be embedded in the inside of the fixed operation tank 207. The rolling hydraulic cylinder 213 drives the rolling block 214 to further pressurize and crush the refined foamed slag, so as to further refine it. After the extrusion is completed, the rolling hydraulic cylinder 213 drives the rolling block 214 to reset, and the lower piezoelectric push rod 208 drives the blocking impact plate 209 to reset. The magnetic adsorption fixed plate 217 is started, and the separation fan 212 drives the further refined foamed slag to move along the fixed operation tank 207 by wind power. At this time, the processing push rod 238 drives the processing moving pipe 239 to rise, so as to block and limit the discharge fixed pipe 216. The refined foamed slag moves towards the slag discharge square pipe 215 under the action of wind power. The iron-containing crushed slag is adsorbed on the side end of the magnetic adsorption fixed plate 217, and the remaining crushed slag is discharged along the slag discharge square pipe 215 under the action of wind power. After the crushed slag screening is completed, the rolling hydraulic cylinder 213 drives the rolling block 214 to seal and limit the slag discharge square pipe 215, the magnetic adsorption fixed plate 217 is closed, and the discharge electric slide rail 210 drives the discharge scraper 211 to push the remaining crushed slag to move. At the same time, the processing push rod 238 drives the processing moving pipe 239 to be inserted into the inside of the processing fixed barrel 218 and embedded in the inside of the ball mill cylinder 221, and pushes the inlet and outlet closing plate 225 to rotate inwards. The crushed slag is discharged into the inside of the ball mill cylinder 221 along the discharge fixed pipe 216 and the processing moving pipe 239. After the discharging is completed, the processing push rod 238 drives the processing moving pipe 239 to reset, and the limiting spring 224 drives the inlet and outlet closing plate 225 to reset. The inlet and outlet closing plate 225 is adsorbed and fixed by the fixed electromagnet 226;

[0065] After the slag enters the ball mill cylinder 221, the ball mill cylinder 221 is driven by the drive motor 220 and the reduction gearbox 219 to rotate along the processing fixed barrel 218. The slag is crushed by rolling in the ball mill cylinder 221. The fully crushed slag is discharged into the inner side of the processing fixed barrel 218 along the ball mill cylinder 221. The iron-containing slag in the slag is adsorbed and fixed by the magnetic separation plate 228. The linkage electric push rod 233 drives the blocking slider 234 to press down. The remaining slag is discharged along the processing fixed barrel 218 under the action of the wind force of the processing fan 229. After both processes are completed, the blocking electric push rod 222 drives the blocking sealing plate 223 to open the ball mill cylinder 221. The connecting electromagnet 231 adsorbs and fixes the discharge operation plate 232. The discharge electric push rod 230 drives the connecting electromagnet 231 and the discharge operation plate 232 to push the remaining hard slag in the ball mill cylinder 221 to be discharged to the position of the magnetic separation mesh box 236. After the discharge is completed, the blocking electric push rod 222 drives the blocking sealing plate 223 to reset. The discharge electric push rod 230 drives the connecting electromagnet 231 and the discharge operation plate 232 to reset. The magnetic separation plate 228 is closed. The drive motor 220 and the reduction gearbox 219 drive the ball mill cylinder 221 to rotate again, thereby driving the cleaning scraper 227 to clean the side end of the processing fixed barrel 218 and scrape off the slag;

[0066] The slag falling into the magnetic separation mesh box 236 is adsorbed by the magnetic separation mesh box 236, and the screening motor 237 and the screening spring 235 drive the magnetic separation mesh box 236 to vibrate, so as to discharge the non-iron-containing impurities, thereby realizing the full treatment of the foam slag;

[0067] The opening and closing motor 318 drives the opening and closing plate 319 to rotate to open the processing fixed barrel 218. The discharge hydraulic cylinder 312 drives the discharge fitting plate 313 to push the slag in the processing fixed barrel 218 into the storage concentration box 306. The discharge electric push rod 314 drives the discharge fitting plate 315 to push the raw material to be discharged into the storage concentration box 306 along the position of the blocking reset plate 316. The reciprocating electric slide rail 305 drives the storage concentration box 306 to move and fit to the side end of the lifting positioning frame 301. The lifting electric slide rail 317 drives the support fixed plate 302 to rise. When it rises to the position of the centralized fixed hopper 307, the discharge motor 303 drives the placement linkage plate 304 to rotate, thereby driving the storage concentration box 306 to put the slag into the inner side of the centralized fixed hopper 307. The storage dispersion barrel 310 storing coke powder is fixed to the side end of the dispersion combination barrel 308 through the threaded pipe 309, thereby realizing feeding;

[0068] After the feeding is completed, the auxiliary operation pipe 404 is opened through the solenoid valve 405, oxygen is discharged into the auxiliary operation pipe 404 from the outside, and then the storage dispersion barrel 310 and the centralized fixed hopper 307 are opened through the flow-limiting valve 311. The oxygen driven by the auxiliary blower 402 pushes the foamed slag and coke powder to move towards the position of the smelting electric furnace 401. The flow-blocking electric push rod 408 drives the flow-blocking closing plate 409 to open the injection fixed pipe 406 along the dispersion combination cylinder 308, and the mixed powder is conveyed into the smelting electric furnace 401 through the U-shaped structure. And through the gas feeding, it is refined, so as to accelerate its smelting speed. After the feeding is completed, the flow-blocking electric push rod 408 drives the flow-blocking closing plate 409 to reset, and the feeding is stopped. At the same time, the flow-blocking electric push rod 408 located at the top of the direct blowing pipe 407 drives the flow-blocking closing plate 409 to open the direct blowing pipe 407 again, so as to realize continuous oxygen supply. The smelting is carried out through the smelting electric furnace 401, and other required raw materials are provided through the auxiliary inlet pipe 410, so as to realize the recovery of iron in the foamed slag.
