Description

Technical Field

[0001] The invention belongs to the technical field of scrap steel feeding, and specifically relates to a scrap steel feeding process, scrap steel feeding equipment and a feeding method after a furnace. Background Art

[0002] Steel resources, as the "second mining industry" of the steel industry, have the advantages of saving energy, reducing pollution, protecting the environment, and recycling, and are widely used. Accordingly, efficient scrap steel processing equipment is urgently needed. Conventionally, scrap steel is used for electric furnace steelmaking to make secondary use of scrap steel. Before the scrap steel enters the electric furnace, it needs to be fed into the electric furnace through feeding equipment. Therefore, the feeding equipment plays a decisive role in the post-furnace fast adding scrap steel process. The post-furnace fast adding cold steel system is suitable for the EAF electric arc furnace equipment process structure that has been rapidly developed in China in recent years. Shorten the smelting cycle, save energy and reduce consumption, and improve the recovery rate.

[0003] Chinese invention patent CN116812583A discloses a scrap steel transportation device, which solves the technical problem of the long blast furnace scrap steel transportation process and the large space required in the prior art. The scrap steel transportation device includes a scrap steel pool, a first feeder, a scrap steel conveying mechanism, a weighing mechanism and a blast furnace conveying mechanism. A first feed port is provided on the top of the scrap steel pool and a first discharge port is provided on the bottom. The scrap steel transportation equipment has low transportation efficiency and poor transportation effect.

[0004] Chinese invention patent CN111071821A discloses a scrap steel slope hopper, a discharge assembly and a support assembly. The discharge assembly includes a plate frame, a discharge plate, a baffle, a fixed plate and a reinforcement assembly. Baffles are welded to the bottom of both sides of the plate frame, and the two ends of the fixed plate are respectively welded to one side of the two baffles; the feeding equipment is difficult to operate and has low operating efficiency, and cannot meet the needs of mass production and processing.

[0005] The existing processes and schemes for adding scrap steel in electric furnace steelmaking have the disadvantages of complex equipment, high investment cost, high secondary heating fuel cost, and uneven molten steel composition. During the electric furnace steelmaking process, if the amount of steel retained in each furnace increases, the amount of steel produced will inevitably decrease. Adding scrap steel during the smelting process after the electric furnace steel is completed will increase the smelting time. The existing processes and schemes for adding scrap steel in electric furnace steelmaking have the disadvantages of complex equipment, high investment cost, high secondary heating fuel cost, and uneven molten steel composition.

[0006] When the above scrap steel feeding equipment is actually used, since the scrap steel falls down along the lower hopper to the inside of the feeding bin for subsequent unloading, the scrap steel is easily accumulated at the gathering point between the feeding bin and the lower hopper, thereby reducing the unloading rate and stability of subsequent scrap.

[0007] At the same time, when the material discharge rate inside the feeding bin needs to be increased, simply increasing the inclination angle of the feeding bin cannot meet the actual material discharge demand, and it is also easy to cause the gap between the feeding bin and the discharge hopper to decrease and cause blockage.

[0008] Since there are a lot of dust and impurities inside the scrap steel, if they are not filtered and recovered, it will easily affect the subsequent re-refining of the scrap steel in the ladle. The filter plate is easily blocked by dust and impurities, thereby reducing the subsequent filtering and recovery effect of dust and impurities in the scrap steel. After long-term use, the inner wall of the feeding bin is prone to adhesion of dust and impurities in the scrap steel. If it is not cleaned after feeding is completed, it is easy to cause pollution to the subsequent feeding of waste materials. Manual cleaning operations are difficult, have low cleaning efficiency, and have high risk factors. Summary of the invention

[0026] The feeding method of the scrap steel feeding device as described above comprises the following steps:

[0027] S1, scrap steel falls along the lower hopper onto the filter plate inside the feed bin, and the feed bin vibrates and causes the scrap steel to slide and discharge continuously;

[0028] S2. When the feed bin drives the inclined block to move up and down, the distance between the top of the inclined block and the bottom of the lower hopper changes, the vertical rod moves up and down along the top groove, the gas inside the top groove circulates with the inside of the side groove, the sliding plate moves laterally along the side groove, the sliding plate reciprocates and scrapes the filter plate laterally and pushes the scrap steel inside the lower hopper to discharge vertically and reciprocates;

The gas inside the top groove enters the side groove and drives the multiple sliding plates to extend outward at different distances. The reciprocating lateral sliding positions of the multiple sliding plates are different, and the ventilation volumes of the side holes and bottom holes outside the multiple side grooves are different.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The present invention further limits the process of adding scrap steel quickly after the furnace, increases the use of scrap steel, greatly reduces power consumption and retains alloy components, increases the amount of steel retained in the electric furnace, shortens the electric furnace smelting cycle, speeds up the steelmaking rhythm, adds cold scrap steel while tapping, and the flushing of high-temperature liquid molten steel in the process of tapping the steel from the electric furnace can make the cold scrap steel heat up and melt evenly and not easy to stick together, so that the scrap steel components are evenly added to the entire ladle of molten steel, the feeding speed can be adjusted according to actual needs, the feeding is uniform, the scrap steel does not stick to block the ladle air vent, and the output of steelmaking is increased without changing the size of the electric furnace, bringing about production increase benefits, low equipment investment cost, no secondary heating fuel cost, low investment and operation costs, and high comprehensive benefits.

[0033] 2. The present invention sets the mutual cooperation of components such as feeding assembly, adjustment assembly, driving assembly and cleaning assembly. The scrap steel feeding equipment is simple to operate, safe and stable, can realize the feeding of scrap steel in one time, is fast and efficient, is convenient for the feeding process of large quantities of scrap steel, and can meet different actual production and processing needs. It has stronger adaptability, higher stability, better cleanliness and stronger structure. At the same time, it can also realize the movement and up and down vibration of the feeding bin, which is convenient for adjusting the feeding rate.

[0034] 3. The present invention sets the mutual cooperation of the components such as the feeding bin, the vertical rod and the matching block. When the feeding bin inside the scrap steel feeding equipment vibrates up and down, it cooperates with the lower hopper to realize the reciprocating lateral movement of the sliding plate and the scraper block, thereby not only improving the feeding efficiency and feeding stability of the scrap steel inside the lower hopper, but also realizing the wind-powered clearing effect of the filter holes with the help of the circulation of gas inside the multiple side holes and the bottom holes, with stronger dredging performance and better cleaning performance.

[0035] 4. The present invention sets the first electric push rod and the second electric push rod and other components to cooperate with each other. When it is necessary to improve the unloading efficiency, the inclination angle of the feeding bin is correspondingly increased, and the position of the unloading hopper is kept stationary, so that the moving positions of multiple sliding plates and scrapers are different, and the adaptive adjustment of the scrap steel unloading rate is further improved, ensuring that the cleaning effect of the filter plate and the dredging efficiency of the unloading hopper match the scrap steel unloading rate, with stronger integrity and better controllability.

[0036] 5. The present invention sets the cooperation between the sliding plate, the scraper block and other components. When the feeding bin is finished unloading, the feeding bin is raised to the maximum distance, and then the up and down vibration of the feeding bin is coordinated to realize the collision between the two corresponding scraper blocks, thereby improving the cleaning effect of the internal structure of the feeding bin, reducing the cleaning difficulty, and effectively avoiding contamination of the subsequent scrap steel feeding.

[0037] 6. The present invention further defines the scrap steel adding process after the furnace, fully utilizes the characteristics of the EAF electric arc furnace process structure layout, and if the original process structure is intervened at an early stage, the modification cost investment is very small. By using this set of process equipment for adding cold steel after the furnace, the smelting cycle can be shortened, the utilization rate of EAF electric arc furnace smelting supporting equipment can be improved, the depreciation cost of supporting equipment per unit time can be reduced, and the recovery rate of scrap steel alloy can be improved. By using this process for adding cold steel after the furnace, arc heating and oxygen blowing alloy consumption in smelting can be avoided. This process for adding cold steel after the furnace fully utilizes the scouring and stirring of scrap steel particles by molten steel flow during steel tapping, and the temperature and composition are uniform.

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] First embodiment

[0052] like Figure 1 As shown, the post-furnace quick scrap steel adding process includes the following steps:

[0053] S1. Scrap from the scrap yard is loaded onto a mobile dump truck through electromagnetic cranes and other loading tools. When the set value is reached, the loading stops. The mobile dump truck crosses the span from the scrap yard and walks to the unloading station on the platform behind the furnace to wait for unloading.

[0054] S2. When the ladle moves to the steel-out station of the electric furnace, the scrap steel feeding equipment moves forward to the feeding station;

[0055] S3. When the electric furnace tilts 15 degrees to discharge steel, the scrap steel feeding equipment and the mobile dump truck are intelligently linked and the scrap steel is discharged by the mobile dump truck through the transition chute to the scrap steel feeding equipment on the steel discharge platform. The scrap steel feeding equipment adds scrap steel to the ladle at the steel receiving position evenly and quickly.

[0056] The main process flow is as follows: the scrap steel from the scrap steel yard is loaded onto the mobile dump truck through electromagnetic crane and other loading tools. The loading is stopped after reaching the set value. The mobile dump truck crosses the span from the scrap steel yard and walks to the unloading station on the platform behind the furnace to wait for unloading. When the ladle moves to the electric furnace tapping station, the scrap steel feeding equipment moves forward to the feeding station. When the electric furnace tilts 15° for tapping, the scrap steel feeding equipment and the mobile dump truck are intelligently linked and opened. The scrap steel is unloaded by the mobile dump truck through the transition chute to the scrap steel feeding equipment on the tapping platform. The scrap steel feeding equipment evenly and quickly adds scrap steel to the ladle at the receiving position.

[0057] Since this process is an online fast scrap steel adding process, the scrap steel adding and the electric furnace steel tapping are carried out simultaneously, and the scrap steel adding time is no longer than the electric furnace steel tapping time, so the original electric furnace smelting cycle is not increased.

[0058] The cost of molten steel = scrap steel + electricity consumption + raw and auxiliary material consumption. Scrap steel consumes electricity during the smelting process, and high-temperature smelting will also cause alloy loss of raw and auxiliary materials. Directly adding scrap steel into the ladle and using the temperature of the molten steel in the ladle to melt the scrap steel can greatly reduce electricity consumption and retain alloy components; at the same time, it can shorten the smelting cycle and improve the yield.

[0059] It can also reduce the amount of steel produced per furnace, increase the amount of steel retained in the electric furnace, shorten the electric furnace smelting cycle, increase the use of scrap steel, and save energy and reduce consumption.

[0060] Therefore, the present invention increases the usage of scrap steel, greatly reduces power consumption and retains alloy components, increases the amount of steel retained in the electric furnace, shortens the electric furnace smelting cycle, speeds up the steelmaking rhythm, adds cold scrap steel while tapping steel, and the flushing of high-temperature liquid molten steel in the process of tapping steel from the electric furnace can make the cold scrap steel heat up and melt evenly and not easy to stick together, so that the scrap steel components are evenly distributed in the entire ladle of molten steel, the feeding speed can be adjusted according to actual needs, the feeding is uniform, the scrap steel does not stick to block the ladle air vent, and the output of steelmaking is increased without changing the size of the electric furnace, bringing increased production benefits, low equipment investment cost, no secondary heating fuel cost, low investment and operation costs, and high comprehensive benefits.

The protective shell 308 wraps and protects the eccentric blocks 310. An elastic rod 303 is provided at the inner bottom of the splicing frame 301. The top of the other end of the elastic rod 303 passes through the splicing frame 301 and is hinged to the bottom of the swing plate 302. Therefore, when the eccentric block 310 drives the feeding bin 101 to move upward, the transmission belt 303 is used to move the feeding bin 101 upward. 06 connects the driving wheel 305 and the driven wheel 307, the driving motor 304 swings upward on the swing plate 302, and the swing plate 302 stretches the elastic rod 303 to swing upward, and when the central shaft 309 drives the eccentric block 310 to continue to rotate and reach the downward position, the eccentric block 310 drives the feeding bin 101 to move downward, and drives the swing plate 302 to rotate downward and return to its original position under the elastic action of the elastic rod 303, and the swing plate 302 drives the driving motor 304 to swing downward and return to its original position, further ensuring the tensioning transmission stability of the driving wheel 305 and the driven wheel 307 at the output end of the driving motor 304 to the transmission belt 306, and the inner top of the splicing frame 301 is connected with a power line 311, and the power line 311 is used to energize the equipment.

[0068] The cleaning component 4 includes an inclined block 401, and a plurality of inclined blocks 401 are provided. The side walls of the inclined blocks 401 are fixedly connected to the inner walls of the feed bin 101, and the bottom of the inclined blocks 401 is in contact with the top of the filter plate 104. The side walls of adjacent inclined blocks 401 fit together. Therefore, the scrap steel inside the lower hopper 102 first falls upward on the plurality of inclined blocks 401, and is then concentratedly guided by the inclined blocks 401 to fall above the filter plate 104 inside the feed bin 101, thereby further improving the concentration and stability of the scrap steel discharge.

[0069] A top groove 402 is provided at the top of the inclined block 401, and a vertical rod 403 is connected to the inside of the top groove 402 in a sealed sliding manner. The vertical rod 403 can slide up and down in a sealed manner inside the top groove 402. A plurality of connecting springs 406 are evenly arranged at the bottom of the vertical rod 403. The bottom of the connecting spring 406 is fixedly connected to the inner bottom of the top groove 402. The setting of the connecting spring 406 further improves the elastic reset effect of the vertical rod 403. The top of the vertical rod 403 is swung and connected to a movable plate 405 through a hinge seat 404. The top of the movable plate 405 matches the bottom of the lower hopper 102. When the feeding bin 101 vibrates upward, the feeding bin 101 drives the multiple inclined blocks 401 to move upward. Since the position of the lower hopper 102 does not change, the distance between the top of the inclined block 401 and the bottom of the lower hopper 102 decreases. The lower hopper 102 applies a downward force to the movable plate 405. The movable plate 405 drives the vertical rod 403 to move downward along the top groove 402 through the hinge seat 404 to squeeze the connecting spring 406.

[0070] A side groove 407 is provided on the side of the inclined block 401 away from the feeding bin 101, and the top groove 402 is connected to the side groove 407. When the vertical rod 403 moves upward along the top groove 402, the gas inside the top groove 402 is squeezed and enters the side groove 407. A sliding plate 408 is slidably connected inside the side groove 407. The air pressure inside the side groove 407 increases and drives the sliding plate 408 to move outward. A sealing ring 410 is provided at the inner wall end of the side groove 407. The inner wall of the sealing ring 410 is sealingly and slidably connected to the outer surface of the sliding plate 408. The setting of the sealing ring 410 ensures the sealing of the gas inside the side groove 407 and the stability of the sliding of the sliding plate 408.

[0071] A matching block 411 is provided on one side of the sliding plate 408 located inside the side groove 407, and a return spring 412 is provided at the other end of the matching block 411. The other end of the return spring 412 is fixedly connected to the inner wall of the side groove 407. The setting of the return spring 412 improves the elastic return performance of the matching block 411. The outer wall of the matching block 411 is sealed and slidably connected to the inner wall of the side groove 407. Therefore, when the air pressure inside the side groove 407 increases, an extrusion force is applied to the matching block 411, and the matching block 411 stretches the return spring 412 and drives the sliding plate 408 to move outward.

[0072] One end of the sliding plate 408 away from the matching block 411 passes through the side groove 407 and is provided with a scraper block 409. The side walls of adjacent scraper blocks 409 fit together, and the bottom of the scraper block 409 matches the top of the filter plate 104. When the sliding plate 408 moves, it simultaneously drives the scraper block 409 to move. The scraper block 409 moves on the top of the filter plate 104 and scrapes and cleans the scrap steel on the top of the filter plate 104. At the same time, when the sliding plate 408 drives the scraper block 409 to move, the sliding plate 408 and the scraper block 409 apply extrusion force to the scrap steel inside the lower hopper 102, thereby facilitating the subsequent scrap steel to reach the top of the filter plate 104 downward.

[0073] A transition hole 417 is provided inside the sliding plate 408, and gas flows inside the transition hole 417. A plurality of side holes 413 are evenly provided on the side wall of the transition hole 417, and a plurality of bottom holes 414 are evenly provided on the bottom of the transition hole 417. Then, the gas flows along the plurality of side holes 413 and the bottom holes 414. A sieve plate 415 is provided inside the side holes 413 and the bottom holes 414. A plurality of sieve holes 416 are evenly provided inside the sieve plate 415. Impurities are filtered and screened by means of the sieve holes 416. The other ends of the bottom holes 414 and the side holes 413 away from the transition hole 417 pass through the sliding plate 408 and are connected to the outside. Therefore, when the sliding plate 408 moves outward, the side holes 413 and the bottom holes 414 are connected to the outside. The gas inside the groove 407 and between the sealing ring 410 and the matching block 411 is squeezed and enters the transition hole 417 along the multiple side holes 413 and the bottom hole 414 inside the side groove 407, while the gas inside the transition hole 417 circulates and is discharged to the outside along the multiple side holes 413 and the bottom hole 414 outside the side groove 407, which not only effectively improves the wind discharge efficiency of the scrap steel inside the feeding bin 101 and the lower hopper 102, but also can clear the filter holes 105 inside the filter plate 104 by wind, further improving the filtering permeability of the filter holes 105 for impurities in the scrap steel, and avoiding the scrap steel blocking the filter holes 105 and reducing the filtering effect during long-term use.

[0074] When the above scrap steel feeding equipment is actually used, since the scrap steel falls downward along the lower hopper 102 to the inside of the feeding bin 101 for subsequent unloading, the scrap steel is easily accumulated at the collection point between the feeding bin 101 and the lower hopper 102, thereby reducing the unloading rate and unloading stability of the subsequent scrap steel; at the same time, when it is necessary to increase the unloading rate inside the feeding bin 101, simply increasing the inclination angle of the feeding bin 101 cannot meet the actual unloading demand, and it is also easy to cause the gap between the feeding bin 101 and the lower hopper 102 to decrease and cause blockage; since the scrap steel There are a large number of dust and impurities inside. If they are not filtered and recovered, it will easily affect the subsequent re-refining of the scrap steel in the ladle. The filter plate 104 is easily blocked by dust and impurities, thereby reducing the subsequent filtering and recovery effect of dust and impurities in the scrap steel. After long-term use, the inner wall of the feeding bin 101 is prone to adhere to dust and impurities in the scrap steel. If it is not cleaned after feeding is completed, it is easy to cause pollution to the subsequent feeding of waste materials. Manual cleaning operations are difficult, have low cleaning efficiency, and have high risk factors.

[0075] Therefore, when scrap steel feeding is required, the controller first controls the electric slide 208 to start and move along the slide rail 207, the electric slide 208 drives the top movable seat 201 to move, the movable seat 201 drives the upper feeding bin 101 to move, and at the same time, since the position of the lower hopper 102 does not change, the feeding bin 101 drives multiple inclined blocks 401 to move when it moves, and the inclined blocks 401 drive multiple movable plates 405 to move. When the feeding port 109 of the feeding bin 101 is directly above the ladle of subsequent electric furnace steelmaking, the tops of the multiple movable plates 405 are all squeezed and contacted with the lower hopper 102.

[0076] Afterwards, the mobile weighing dump truck moves along the fixed platform 103 to above the lower hopper 102, and the mobile weighing dump truck starts and pours the scrap steel inside into the lower hopper 102. The scrap steel inside the lower hopper 102 continues to move downward and reaches the inside of the feeding bin 101, and is gathered in the middle position of the top of the filter plate 104 under the inclined guidance of multiple inclined blocks 401, thereby facilitating the subsequent unloading and filtering and screening process of the scrap steel.

[0077] At the same time, the controller controls the drive motor 304 to start and the output end drives the driving wheel 305 to rotate, the driving wheel 305 drives the driven wheel 307 to rotate through the transmission belt 306, the driven wheel 307 drives the central axis 309 to rotate inside the middle hole 312, and the central axis 309 synchronously drives the two eccentric blocks 310 to rotate, when the eccentric block 310 swings upward, the feeding bin 101 is driven to swing upward by the inertia of the eccentric block 310, and when the feeding bin 101 swings upward, the transmission belt 306 is driven to swing upward through the central axis 309 and the driven wheel 307, the transmission belt 306 drives the driving wheel 305 to swing upward, and the driving wheel 305 drives the swing plate 302 to stretch the elastic rod 303 to swing upward through the drive motor 304.

[0078] When the central shaft 309 continues to drive the two eccentric blocks 310 to rotate and swing downward, the eccentric blocks 310 drive the feeding bin 101 to swing downward by virtue of the inertia of the eccentric blocks 310. At this time, the elastic force of the elastic rod 303 drives the swing plate 302 to swing downward and return to its original position. The swing plate 302 drives the driving wheel 305 to swing downward and return to its original position through the driving motor 304. The driving wheel 305 drives the driven wheel 307 to swing downward and return to its original position through the transmission belt 306. The driven wheel 307 drives the feeding bin 101 to swing downward and return to its original position through the central shaft 309. While the feeding bin 101 vibrates up and down and discharges the scrap steel inside, the tension state of the driving wheel 305 and the driven wheel 307 on the transmission belt 306 is further guaranteed, thereby improving the rotation stability and transmission efficiency of the central shaft 309 and the eccentric block 310.

[0079] When the feeding bin 101 vibrates up and down, the feeding bin 101 drives the internal filter plate 104 to vibrate up and down synchronously, and the filter plate 104 drives the scrap steel above to vibrate up and down, which not only effectively improves the vibration discharge efficiency of the scrap steel above the filter plate 104, but also can vibrate and clean the dust and impurities inside the scrap steel, so that the dust and impurities can move downward along the filter holes 105 to the inside of the impurity box 106 for recovery.

[0080] When the feeding bin 101 swings upward, the feeding bin 101 drives the inclined block 401 to move upward, and the distance between the top of the inclined block 401 and the bottom of the lower hopper 102 is reduced, and the top of the movable plate 405 and the bottom of the lower hopper 102 squeeze and collide with each other. With the help of this collision force, a vibration effect can be applied to the bottom of the lower hopper 102, thereby avoiding the blockage of scrap steel inside the lower hopper 102, and effectively improving the unloading efficiency of the scrap steel inside the lower hopper 102. When the movable plate 405 is subjected to a downward squeezing force, the movable plate 405 drives the vertical rod 403 to move downward along the top groove 402 through the hinge seat 404 to squeeze the connecting spring 406. As the squeezing pressure of the vertical rod 403 on the internal air pressure of the top groove 402 increases, the gas inside the top groove 402 flows along the bottom of the top groove 402 to the inside of the side groove 407, and the internal air pressure of the side groove 407 increases and drives the matching block 411 to stretch the reset spring 412 and move outward away from the end of the top groove 402, and the matching block 411 drives the sliding plate 408 to move outward along the side groove 407, and the sliding plate 408 drives the scraper block 409 to move synchronously, and the scraper block 409 scrapes the top of the filter plate 104 laterally, thereby further improving the clearing effect of the filter holes 105 inside the filter plate 104, and ensuring the dredging and filtering properties of the filter holes 105 inside the filter plate 104.

[0081] When the sliding plate 408 drives the scraper block 409 to move, the sliding plate 408 and the scraper block 409 exert a lateral thrust on the bottom of the scrap steel between the lower hopper 102 and the filter plate 104. Then, under the action of the lateral thrust, the scrap steel is pushed upward along the lower hopper 102 on the top of the filter plate 104, thereby improving the fluidity of the scrap steel between the lower hopper 102 and the feed bin 101. When the matching block 411 moves along the side groove 407, the gas between the matching block 411 and the sealing ring 410 is squeezed, so that part of the gas flows along the multiple side holes 413 and the bottom holes 414 in the side groove 407. 14 enters the transition hole 417, and the gas in the transition hole 417 is finally discharged along the multiple side holes 413 and the bottom hole 414 outside the side groove 407, further improving the feeding efficiency of the scrap steel above the filter plate 104, and with the help of the wind force, the dust and impurities in the filter hole 105 can be cleared by wind to ensure the filterability and unblockability of the filter hole 105. At the same time, the discharge of the gas to the outside can also reversely clear the multiple sieve holes 416 in the sieve plate 415 by wind force, avoiding the clogging of the sieve holes 416 and reducing the filtering and screening effect during long-term use.

[0082] As the central axis 309 rotates and drives the eccentric blocks 310 on both sides to swing downward, the feeding bin 101 swings downward, and the feeding bin 101 drives multiple inclined blocks 401 to move downward. The distance between the inclined blocks 401 and the lower hopper 102 continues to increase, and the vertical rod 403 is driven to move upward along the top groove 402 under the elastic force of the connecting spring 406. The vertical rod 403 drives the movable plate 405 to move upward through the hinge seat 404, and the movable plate 405 fits against the bottom of the lower hopper 102 to prevent the scrap steel inside the lower hopper 102 from falling to the top of the inclined block 401 and affecting the subsequent unloading stability.

[0083] When the vertical rod 403 moves upward along the top groove 402, the volume at the bottom of the top groove 402 increases and the pressure decreases. Under the action of negative pressure, a suction force is applied to the matching block 411 inside the side groove 407, and the elastic force of the connecting spring 406 drives the matching block 411 to move closer to the end of the top groove 402. The matching block 411 drives the sliding plate 408 to move inward along the side groove 407 simultaneously, and the sliding plate 408 drives the scraper block 409 to move closer to the end of the inclined block 401. The lateral supporting force exerted by the sliding plate 408 and the inclined block 401 on the scrap steel between the filter plate 104 and the lower hopper 102 is reduced, and the scrap steel slides down rapidly along the lower hopper 102 under the action of its own gravity, further improving the unloading efficiency of the scrap steel inside the lower hopper 102.

[0084] And when the matching block 411 moves, the volume between the matching block 411 and the sealing ring 410 increases and the pressure decreases. Under the action of negative pressure, suction force is applied to the transition hole 417 through the multiple side holes 413 and the bottom hole 414 inside the side groove 407. Under the action of the suction force, the side holes 413 and the bottom holes 414 outside the side groove 407 apply suction force, which not only improves the wind suction and clearing effect on the filter holes 105 and the sieve holes 416, but also can apply suction force to the scrap steel, thereby improving the scrap steel unloading efficiency.

[0085] At the same time, when it is necessary to increase the unloading rate of the feeding bin 101, the controller controls the multiple first electric push rods 202 to start and the output end is extended, and the first electric push rods 202 drive the feeding bin 101 to move upward near the lower hopper 102 end through the mounting seat 204 and the spring seat 205, the inclination angle of the feeding bin 101 increases, and the unloading rate of the scrap steel inside the feeding bin 101 increases accordingly, and because the feeding bin 101 is tilted upward near the side of the lower hopper 102, the gap between the top of the multiple inclined blocks 401 on this side and the lower hopper 102 is reduced, and the lower hopper 102 squeezes the movable plate 405 to move downward, and the movable plate 405 drives the vertical rod 403 to squeeze the connecting spring 406 along the top groove 402 through the hinge seat 404 to move downward, and the inside of the top groove 402 enters the side groove 407 As the amount of gas in the upper part increases, the matching block 411 initially drives the sliding plate 408 and the scraper block 409 to move outward to increase the distance, and the length of the sliding plate 408 extending outward from the side hole 413 and the bottom hole 414 increases. The distances at which the multiple sliding plates 408 extend outward along the side groove 407 are different, and gradually decrease from the lower hopper 102 end to the feeding port 109 end. Therefore, when the feeding bin 101 continuously vibrates up and down, the positions and amounts of gas discharged from the side holes 413 and the bottom holes 414 inside the multiple sliding plates 408 are different, which further improves the wind clearing effect of the blockage inside the filter hole 105, and at the same time improves the lateral movement of the scrap steel inside the lower hopper 102 and the wind unloading efficiency, to ensure that the scrap steel inside the lower hopper 102 can be unloaded stably and efficiently.

[0086] After the unloading of scrap steel is completed, the controller controls the first electric push rod 202 and the second electric push rod 203 to start and reach the maximum value, then the first electric push rod 202 and the second electric push rod 203 drive the feeding bin 101 to move upward to the maximum distance through the mounting seat 204 and the spring seat 205, the feeding bin 101 drives multiple inclined blocks 401 to move upward to the maximum distance, the distance between the top of the inclined block 401 and the bottom of the lower hopper 102 reaches the minimum value, the vertical rod 403 moves downward along the top groove 402 to the minimum value, the corresponding top groove 402 The internal gas volume entering the side groove 407 reaches the maximum value, and under the action of the internal air pressure of the side groove 407, it drives the matching block 411 to move away from the top groove 402 to the maximum value, the matching block 411 drives the sliding plate 408 and the scraper block 409 to move outward to the maximum value, and the feeding bin 101 vibrates up and down. When the vibration squeezing force of the movable plate 405 and the lower hopper 102 reaches the maximum value, the vibration squeezing force applied to the scrap steel inside the lower hopper 102 can reach the maximum value by means of the vibration squeezing force, thereby further improving the vibration cleaning effect on the scrap steel inside the lower hopper 102, and the matching block 411 drives the sliding plate 408 and the scraper block 409 to reciprocate along the side groove 407 to reach the maximum value, and the two facing scraper blocks 409 collide with each other, thereby further improving the vibration cleaning effect on the dust and impurities attached to the outer surfaces of the scraper blocks 409 and the sliding plates 408, and the vibration is transmitted to the filter plate 104, thereby driving the filter plate 104 to vibrate inside the feeding bin 101, thereby achieving the vibration cleaning effect on the filter plate 104 and the inner wall of the feeding bin 101, and the outer surface of the inclined block 401, thereby improving the cleaning effect and effectively avoiding contamination of the subsequent scrap steel feeding.

[0087] The two sliding plates 408 facing each other at this time are both extended the longest distance along the side grooves 407, and the two sliding plates 408 are matched with the top of the filter plate 104. The scrap steel and dust impurities remaining on the top of the filter plate 104 can be scraped and cleaned with the lateral reciprocating movement of the two sliding plates 408, thereby ensuring the cleanliness of the filter plate 104. Moreover, the gas inside the side grooves 407 enters the transition holes 417 along the multiple side holes 413 and the bottom holes 414 inside the side grooves 407, and the gas inside the transition holes 417 continuously circulates along the multiple side holes 413 and the bottom holes 414 outside the side grooves 407, and the multiple side holes 413 and the bottom holes 414 outside the side grooves 407 are directly facing the multiple filter holes 105 inside the filter plate 104. With the help of the wind force, the filter holes 105 can be thoroughly and effectively cleaned by wind, thereby further improving the dredging and filtering properties of the filter holes 105, and avoiding affecting the subsequent vibration filtering and feeding of scrap steel.

[0088] After the cleaning of the inside of the feeding bin 101 is completed, the controller controls the driving motor 304 to stop working, and at the same time the electric slide 208 starts in the reverse direction and moves in the reverse direction along the slide rail 207 to return to the original position, and then waits for the subsequent unloading of scrap steel.

[0089] The equipment is simple to operate, safe and stable, can feed scrap steel at one time, is fast and efficient, is convenient for feeding large quantities of scrap steel, meets different actual production and processing needs, has stronger adaptability, higher stability, better cleanliness and stronger structure, and can also realize the movement and up and down vibration of the feeding bin 101, so as to facilitate the adjustment of the feeding rate; and when the feeding bin 101 vibrates up and down, it cooperates with the lower hopper 102 to realize the reciprocating lateral movement of the sliding plate 408 and the scraper block 409, thereby not only improving the feeding efficiency and feeding stability of the scrap steel inside the lower hopper 102, but also realizing the wind-powered clearing effect of the filter hole 105 with the help of the circulation of gas inside the multiple side holes 413 and the bottom hole 414, so that the dredging performance is stronger and the cleanliness is better; and when it is needed To improve the unloading efficiency, the inclination angle of the feeding bin 101 is correspondingly increased, and the position of the unloading hopper 102 is kept stationary, so that the multiple sliding plates 408 and the scraper blocks 409 move to different positions, further improving the adaptive adjustment of the scrap steel unloading rate, ensuring that the cleaning effect of the filter plate 104 and the dredging efficiency of the unloading hopper 102 match the scrap steel unloading rate, with stronger integrity and better controllability; when the feeding bin 101 completes unloading, the feeding bin 101 is raised to the maximum distance, and then the up and down vibration of the feeding bin 101 is coordinated to realize the collision of the corresponding two scraper blocks 409, thereby improving the cleaning effect of the internal structure of the feeding bin 101, reducing the cleaning difficulty, and effectively avoiding contamination of the subsequent scrap steel feeding.

[0090] The feeding method of the scrap steel feeding device as described above comprises the following steps:

[0091] S1. Scrap steel falls along the lower hopper 102 onto the filter plate 104 inside the feeding bin 101. The feeding bin 101 vibrates and causes the scrap steel to slide and discharge continuously.

[0092] S2. When the feeding bin 101 drives the inclined block 401 to move up and down, the distance between the top of the inclined block 401 and the bottom of the lower hopper 102 changes, the vertical rod 403 moves up and down along the top groove 402, the gas inside the top groove 402 circulates with the inside of the side groove 407, the sliding plate 408 moves laterally along the side groove 407, the sliding plate 408 reciprocates and scrapes the filter plate 104 laterally and pushes the scrap steel inside the lower hopper 102 to discharge vertically and reciprocates.

[0093] S3. The gas inside the side groove 407 flows inside the transition hole 417 along the multiple side holes 413 and the bottom hole 414 inside the side groove 407, and the gas inside the transition hole 417 flows inside the multiple side holes 413 and the bottom hole 414 outside the side groove 407. The gas flowing through the side holes 413 and the bottom holes 414 exerts a reciprocating wind force on the scrap steel on the filter plate 104 and the dust and impurities inside the filter plate 104.

[0094] S4. When the feeding rate needs to be increased, the inclination angle of the feeding bin 101 increases, and the multiple vertical rods 403 move downward along the top groove 402 at different distances, and gradually decrease from one end of the lower hopper 102 to the other end. The internal gas of the top groove 402 enters the side groove 407 and drives the multiple sliding plates 408 to extend outward at different distances. The reciprocating lateral sliding positions of the multiple sliding plates 408 are different, and the ventilation volumes of the side holes 413 and the bottom holes 414 outside the multiple side grooves 407 are different.

[0095] By further limiting the feeding method, the feeding rate can be increased and the feeding effect can be guaranteed.
