Description

Technical Field

[0001] This invention relates to the field of steel slag treatment technology, and in particular to a dust removal mechanism and method for treating steel slag. Background Technology

[0002] Steel slag is an industrial solid waste, the slag discharged from steelmaking. Depending on the furnace type, it is classified as converter slag, open-hearth furnace slag, and electric furnace slag. The main mineral phases are tricalcium silicate, dicalcium silicate, calcium magnesium olivine, calcium magnesium rhodochrosite, calcium aluminoferrite, and solid solutions formed by oxides of silicon, magnesium, iron, manganese, and phosphorus. It also contains small amounts of free calcium oxide, metallic iron, and fluorapatite. In some regions, due to the presence of titanium and vanadium in the ore, steel slag may also contain trace amounts of these components. The content of various components in steel slag varies considerably depending on the type of steelmaking furnace, the steel grade, and the stage of smelting for each heat. The processing of steel slag generates a large amount of dust, thus requiring dust collection and treatment by a dust removal system.

[0003] Existing dust collection systems for steel slag processing only collect dust generated during various steel slag operations. However, after processing, some dust and impurities adhere to the surface of the steel slag and cannot be removed due to their high adhesion. This results in a significant amount of dust being generated in subsequent operations, thus reducing the value of the dust collection system. Summary of the Invention

[0004] This invention discloses a dust removal mechanism for processing steel slag, aiming to solve the technical problem that existing dust removal mechanisms for processing steel slag only collect dust generated during various operations of steel slag. However, after processing, some dust and impurities adhere to the surface of the steel slag and cannot be removed due to their high adhesion. This leads to the continued generation of a lot of dust in subsequent operations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust removal mechanism for processing steel slag includes a dust collection box. A reverse scraping assembly is located near the top of the dust collection box. The reverse scraping assembly includes a bottom plate. Two mounting brackets are fixedly connected to the outer side of the bottom plate, and both mounting brackets are fixedly connected to the inside of the dust collection box. An annular sliding groove is formed at the top of the bottom plate, and an annular sliding rod is slidably connected inside the annular sliding groove. A rotating frame is fixedly connected to the top of the annular sliding rod. A driven gear is fixedly connected near the middle of the rotating frame. An outer ring frame is fixedly connected to the outer side of the rotating frame near the bottom end, and partitions are fixedly connected at equal intervals on the inner side of the rotating frame. The inner side of the outer ring frame between every two adjacent partitions is fixedly connected to... The dust collector has a hydraulic cylinder, and an ejector plate is fixedly connected to the output end of the hydraulic cylinder. A drive motor is fixedly connected to the top of the dust collector, and a rotating shaft is fixedly connected to the output shaft of the drive motor via a coupling. Inner connecting rods are distributed in a ring on the outer side of the rotating shaft near the bottom. The outer side of multiple inner connecting rods is fixedly connected to the same sealing inner cylinder. Scrapers are fixedly connected at equal intervals on the outer side of the sealing inner cylinder. The sealing inner cylinder and the bottom plate form a cavity except for the opening at the top. A second drive motor is fixedly connected to the top of one of the mounting brackets, and a drive shaft is fixedly connected to the output shaft of the second drive motor via a coupling. A drive gear is fixedly connected to the outer side of the drive shaft, and the drive gear and the driven gear mesh with each other.

[0007] Equipped with a reverse scraping component, once the steel slag is introduced into the rotating frame, both drive motor one and drive motor two start, rotating in opposite directions. During the rotation of the frame, the hydraulic cylinder periodically adjusts to drive the ejector plate, pushing the steel slag into contact with the counter-rotating scraper. The scraper removes dust and impurities from the outside of the steel slag. The impact force between the reverse scraper and the steel slag is significant, and the repeated operation of the scraper effectively removes dust and impurities from the outside of the steel slag, maximizing the removal of these contaminants. Simultaneously, dust pump two is activated, collecting the scraped dust and impurities through suction holes in the top hollow suction plate and directing them into the dust collection box, thereby improving the dust removal efficiency during steel slag processing.

[0008] In a preferred embodiment, the bottom end plate has an ejection hole at its bottom and an installation hole at its top. A feeding frame is fixedly connected to the inner wall of the installation hole. The feeding frame is located between the sealed inner cylinder and the rotating frame. A top hollow dust collection plate is fixedly connected to the top inner wall of the dust collection box. The top hollow dust collection plate is staggered from the feeding frame. Two dust collection holes are equidistantly opened at the bottom of the top hollow dust collection plate.

[0009] In a preferred embodiment, two grounding frames are fixedly connected to the outside of the dust collection box, and a dust collection box is fixedly connected to the top of one of the grounding frames. A second dust collection pump is fixedly connected to the top of the dust collection box. The suction end of the second dust collection pump is connected to the inside of the top hollow suction plate through a pipe. The dust conveying end of the second dust collection pump is fixedly connected to a conveying pipe, and the other end of the conveying pipe is inserted into the inside of the dust collection box.

[0010] In a preferred embodiment, a guide frame is fixedly connected inside the ejection hole, and the guide frame is located at the center of the dust collection box. A random impact detachment component is provided below the guide frame, and the random impact detachment component includes a mounting ring rod.

[0011] In a preferred embodiment, two connecting brackets are fixedly connected to the outer side of the mounting ring rod, and both connecting brackets are fixedly connected to the inside of the dust collector box. Curved impact rods are distributed in a ring on the outer side of the mounting ring rod.

[0012] In a preferred embodiment, the guide frame is fixedly connected to two shaft plates on both sides near the bottom, and a drive motor is fixedly connected to the outer side of one of the shaft plates. The output shaft of the drive motor is fixedly connected to a drive shaft through a coupling. The other end of the drive shaft is connected to the outer side of another shaft plate through a bearing. Disordered rods are distributed in a ring on the outer side of the drive shaft, and the disordered rods are located between multiple bending impact rods.

[0013] By incorporating a staggered impact detachment component, after passing through the reverse scraping component, the steel slag falls along the guide frame into the staggered rods. The drive motor three is then activated, causing each staggered rod to rotate and impact the steel slag, thus accelerating the removal of dust and impurities from the outside of the steel slag. Simultaneously, the presence of the curved impact rods increases the probability of the steel slag being impacted, ensuring that most of the steel slag undergoes the impact and detachment process, thereby further improving the dust removal effect.

[0014] In a preferred embodiment, the dust collection box is provided with a bottom receiving buffer assembly on the inner side near the bottom end, and the bottom receiving buffer assembly includes a conical guide frame. The top of the conical guide frame is connected to a pressure buffer plate at equal intervals by hinges. The bottom of each pressure buffer plate is fixedly connected to a buffer spring rod, and the other end of the buffer spring rod is fixedly connected to the outer side of the conical guide frame.

[0015] In a preferred embodiment, a support ring plate is fixedly connected to the bottom inner wall of the dust collector, and shock-absorbing spring rods are distributed in a ring on the top of the support ring plate. A conical guide frame is fixedly connected to the top of multiple shock-absorbing spring rods. A guide ring plate is fixedly connected to the inner side of the dust collector near the conical guide frame. Two discharge holes are opened at the bottom of the dust collector located between the guide ring plate and the conical guide frame.

[0016] By incorporating a bottom-feeding buffer assembly, after the steel slag undergoes dust removal treatment, it falls inside the dust collector. During its descent, the steel slag first impacts the various downward-pressing buffer plates, where it is initially buffered by the buffer spring rods below. The remaining force of the steel slag then impacts the conical guide frame, where the shock-absorbing spring rods below provide secondary buffering. This ensures that the steel slag can be smoothly discharged through the discharge hole, preventing the falling steel slag from affecting the stability of the dust collector and reducing damage to the dust collector.

[0017] In a preferred embodiment, the dust collection box is provided with a through-type dust collection component on the inner side outside the reverse scraping component and the random impact detachment component. The through-type dust collection component includes an annular connecting pipe. The annular connecting pipe has a connecting hole on its downward-facing outer side. A through-type pipe is fixedly connected inside each connecting hole. A dust collection hole is opened at equal intervals on the outer side of each through-type pipe. Two mounting blocks are fixedly connected to the outer side of the annular connecting pipe. Both mounting blocks are fixedly connected to the inner side of the dust collection box. A dust pump is fixedly connected to the top of the grounding frame. A dust collection pipe is fixedly connected to the dust collection end of the dust pump. The other end of the dust collection pipe is inserted into the inside of the annular connecting pipe. A dust guide pipe is fixedly connected to the dust collection end of the dust pump. The other end of the dust guide pipe is inserted into the inside of the dust collection box.

[0018] By incorporating a through-type dust collection component, after the steel slag undergoes dual dust removal operations via a reverse scraping component and a random impact detachment component, dust and impurities on the outside of the steel slag are removed. Then, dust pump one is activated, collecting dust and impurities from top to bottom of the dust collection box through the suction holes on each through-type pipe. This ensures that the amount of dust and impurities inside the dust collection box is minimized, preventing dust and impurities from being discharged into the atmosphere through the discharge port or the upper feed frame, thus improving the usability of the dust collection mechanism.

[0019] A dust removal method for treating steel slag, using a dust removal mechanism for treating steel slag as described above, the dust removal method comprising the following steps:

[0020] Step 1: After the steel slag is introduced into the rotating frame, both drive motor 1 and drive motor 2 are started. Drive motor 1 and drive motor 2 rotate in opposite directions. During the rotation of the rotating frame, the hydraulic cylinder is periodically adjusted to drive the push plate to push the steel slag, so that it comes into contact with the scraper rotating in the opposite direction. The scraper scrapes off the dust and impurities on the outside of the steel slag. The impact force between the scraper and the steel slag is greater. During the repeated operation of the scraper, the dust removal operation on the outside of the steel slag is achieved. The second dust pump is started. The second dust pump collects the scraped dust and impurities through the dust suction hole 2 on the top hollow dust suction plate and puts them into the dust collection box.

[0021] Step 2: After passing through the reverse scraping component, the steel slag falls into the disordered rods along the guide frame. The drive motor 3 is started, and the drive motor 3 drives each disordered rod to rotate the steel slag, so that the steel slag hits each curved impact rod. The impact accelerates the removal of dust and impurities from the outside of the steel slag.

[0022] Step 3: After the steel slag undergoes dual dust removal operations by the reverse scraping component and the random impact detachment component, the dust and impurities on the outside of the steel slag are removed. Then, start the first dust pump. The first dust pump collects dust and impurities from top to bottom of the dust collection box through the dust suction holes on each through pipe, ensuring that the amount of dust and impurities inside the dust collection box is minimized.

[0023] Step 4: After the steel slag has undergone dust removal treatment, it falls inside the dust removal box. During the fall, the steel slag first impacts each of the downward pressure buffer plates, and the buffer spring rods below them achieve initial buffering. The remaining force of the steel slag impacts the conical guide frame, and the shock-absorbing spring rods below the conical guide frame achieve secondary buffering, thereby ensuring that the steel slag can be smoothly discharged through the discharge hole.

[0024] As can be seen from the above, the dust removal mechanism for processing steel slag provided by the present invention has the following characteristics: when the steel slag is introduced into the rotating frame, both drive motor one and drive motor two are started. Drive motor one and drive motor two rotate in opposite directions. During the rotation of the rotating frame, the hydraulic cylinder is periodically adjusted to drive the push plate to push the steel slag, so that it comes into contact with the counter-rotating scraper. The scraper scrapes off the dust and impurities on the outside of the steel slag. The impact force between the counter-rotating scraper and the steel slag is relatively large. During the repeated operation of the scraper, the dust removal operation on the outside of the steel slag is realized, and the technical effect of scraping off the dust and impurities on the outside of the steel slag to the greatest extent is achieved.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] The dust removal mechanism for steel slag processing disclosed in this invention is mainly applicable to existing dust removal mechanisms for steel slag processing. These mechanisms simply collect dust generated during various operations on the steel slag. However, after processing, some dust and impurities adhere to the surface of the steel slag and cannot be removed due to their high adhesion. This results in a situation where a lot of dust is still generated in subsequent operations.

[0037] Reference Figures 1-9 A dust removal mechanism for processing steel slag includes a dust collection box 1. A reverse scraping assembly 5 is provided near the top of the dust collection box 1. The reverse scraping assembly 5 includes a bottom plate 520. Two mounting brackets 511 are fixedly connected to the outer side of the bottom plate 520, and both mounting brackets 511 are fixedly connected to the inside of the dust collection box 1. An annular sliding groove is formed at the top of the bottom plate 520, and an annular sliding rod 519 is slidably connected inside the annular sliding groove. A rotating frame 514 is fixedly connected to the top of the annular sliding rod 519. A driven gear plate 507 is fixedly connected near the middle of the rotating frame 514. An outer ring frame 508 is fixedly connected to the outer side of the rotating frame 514 near the bottom end, and partitions 505 are fixedly connected at equal intervals on the inner side of the rotating frame 514. A hydraulic cylinder 509 is fixedly connected to the inner side of the outer ring frame 508 between every two adjacent partitions 505. The output end of the hydraulic cylinder 509 is fixedly connected to the push plate 506. The top of the dust collector 1 is fixedly connected to the drive motor 501, and the output shaft of the drive motor 501 is fixedly connected to the rotating shaft 515 through a coupling. The outer side of the rotating shaft 515 near the bottom end has inner connecting rods 522 distributed in a ring. The outer side of multiple inner connecting rods 522 is fixedly connected to the same sealing inner cylinder 518. The outer side of the sealing inner cylinder 518 is fixedly connected to scrapers 516 at equal intervals. The sealing inner cylinder 518 and the bottom plate 520 form a cavity except for the opening at the top end. The top of one of the mounting brackets 511 is fixedly connected to the drive motor 510, and the output shaft of the drive motor 510 is fixedly connected to the drive shaft 513 through a coupling. The outer side of the drive shaft 513 is fixedly connected to the drive gear 512, and the drive gear 512 and the driven gear 507 mesh with each other.

[0038] In a specific application scenario, after the steel slag is introduced into the rotating frame 514, both drive motor 1 501 and drive motor 2 510 are started. Drive motor 1 501 and drive motor 2 510 rotate in opposite directions. During the rotation of the rotating frame 514, the hydraulic cylinder 509 is periodically adjusted to drive the push plate 506 to push the steel slag, so that it comes into contact with the counter-rotating scraper 516. The scraper 516 scrapes off the dust and impurities on the outside of the steel slag. The impact force between the counter-rotating scraper 516 and the steel slag is relatively large. During the repeated operation of the scraper 516, the dust removal operation on the outside of the steel slag is achieved, and the dust and impurities on the outside of the steel slag are scraped off to the greatest extent. At the same time, the dust pump 2 502 is started. The dust pump 2 502 collects the scraped dust and impurities through the dust suction hole 2 517 on the top hollow dust suction plate 504 and introduces them into the dust collection box 4, thereby improving the dust removal effect in the steel slag processing.

[0039] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4In a preferred embodiment, the bottom plate 520 has an ejection hole 521 at its bottom and an installation hole at its top. A feed frame 6 is fixedly connected to the inner wall of the installation hole. The feed frame 6 is located between the sealed inner cylinder 518 and the rotating frame 514. A top hollow dust collection plate 504 is fixedly connected to the top inner wall of the dust collection box 1. The top hollow dust collection plate 504 is staggered from the feed frame 6. Dust collection holes 517 are equidistantly opened at the bottom of the top hollow dust collection plate 504. Two grounding brackets 2 are fixedly connected to the outside of the dust collection box 1. A dust collection box 4 is fixedly connected to the top of one of the grounding brackets 2. A second dust collection pump 502 is fixedly connected to the top of the dust collection box 1. The dust collection end of the second dust collection pump 502 is connected to the inside of the top hollow dust collection plate 504 through a pipe. The dust conveying end of the second dust collection pump 502 is fixedly connected to a conveying pipe 503. The other end of the conveying pipe 503 is inserted into the inside of the dust collection box 4.

[0040] Reference Figure 1 , Figure 2 and Figure 6 In a preferred embodiment, a guide frame 8 is fixedly connected inside the ejection hole 521, and the guide frame 8 is located at the center of the dust collection box 1. A disordered impact release assembly 9 is provided below the guide frame 8. The disordered impact release assembly 9 includes a mounting ring rod 901. Two connecting brackets 903 are fixedly connected to the outer side of the mounting ring rod 901, and both connecting brackets 903 are fixedly connected to the inside of the dust collection box 1. Bending impact rods 904 are distributed in a ring on the outer side of the mounting ring rod 901. Shaft plates 906 are fixedly connected to both sides of the guide frame 8 near the bottom. A drive motor 905 is fixedly connected to the outer side of one of the shaft plates 906. The output shaft of the drive motor 905 is fixedly connected to a drive shaft 902 through a coupling. The other end of the drive shaft 902 is connected to the outer side of another shaft plate 906 through a bearing. Disordered rods 907 are distributed in a ring on the outer side of the drive shaft 902, and the disordered rods 907 are located between multiple bending impact rods 904.

[0041] It should be noted that after the steel slag passes through the reverse scraping component 5, it falls along the guide frame 8 into the disordered rods 907. The drive motor 905 is activated, and the drive motor 905 drives each disordered rod 907 to rotate the steel slag, causing the steel slag to collide with each curved impact rod 904. Through the impact, the dust and impurities on the outside of the steel slag are accelerated to fall off. At the same time, the presence of the curved impact rods 904 increases the probability of the steel slag being impacted, ensuring that most of the steel slag will pass through the impact and fall off stage, thereby further improving the dust removal effect of the steel slag.

[0042] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8In a preferred embodiment, a bottom receiving buffer assembly 10 is provided on the inner side of the dust collector 1 near the bottom end. The bottom receiving buffer assembly 10 includes a conical guide frame 1001. A downward pressure buffer plate 1005 is connected at equal intervals above the conical guide frame 1001 via hinges. A buffer spring rod 1006 is fixedly connected to the bottom of each downward pressure buffer plate 1005. The other end of the buffer spring rod 1006 is fixedly connected to the outer side of the conical guide frame 1001. A support ring plate 1002 is fixedly connected to the inner wall of the bottom of the dust collector 1. Shock-absorbing spring rods 1003 are distributed in a ring on the top of the support ring plate 1002. The conical guide frame 1001 is fixedly connected to the top of the multiple shock-absorbing spring rods 1003. A guide ring plate 1004 is fixedly connected to the inner side of the dust collector 1 near the conical guide frame 1001. Two discharge holes 7 are opened at the bottom of the dust collector 1 between the guide ring plate 1004 and the conical guide frame 1001.

[0043] Specifically, after the steel slag undergoes dust removal treatment, it falls inside the dust collector 1. During the fall, the steel slag first impacts each of the downward pressure buffer plates 1005, and is initially buffered by the buffer spring rods 1006 below them. The remaining force of the steel slag impacts the conical guide frame 1001, and the shock-absorbing spring rods 1003 below the conical guide frame 1001 provide secondary buffering. This ensures that the steel slag can be smoothly discharged through the discharge hole 7, preventing the falling steel slag from affecting the stability of the dust collector 1, and reducing the damage to the dust collector 1.

[0044] Reference Figure 1 , Figure 2 and Figure 9 In a preferred embodiment, a through-type suction assembly 3 is provided on the inner side of the dust collection box 1 outside the reverse scraping assembly 5 and the random impact detachment assembly 9. The through-type suction assembly 3 includes an annular connecting pipe 303. The annular connecting pipe 303 has a connecting hole on its downward-facing outer side. A through-type pipe 304 is fixedly connected inside each connecting hole. Suction holes 305 are equally spaced on the outer side of each through-type pipe 304. Two mounting blocks 307 are fixedly connected to the outer side of the annular connecting pipe 303. Both mounting blocks 307 are fixedly connected to the inner side of the dust collection box 1. A suction pump 301 is fixedly connected to the top of the grounding frame 2. A suction pipe 302 is fixedly connected to the suction end of the suction pump 301. The other end of the suction pipe 302 is inserted into the inside of the annular connecting pipe 303. A dust guide pipe 306 is fixedly connected to the dust conveying end of the suction pump 301. The other end of the dust guide pipe 306 is inserted into the inside of the dust collection box 4.

[0045] Specifically, after the steel slag undergoes dual dust removal operations via the reverse scraping component 5 and the random impact detachment component 9, the dust and impurities on the outside of the steel slag are removed. The dust suction pump 301 is then activated. The dust suction pump 301 collects dust and impurities from top to bottom of the dust collection box 1 through the dust suction holes 305 on each through-pipe 304, ensuring that the amount of dust and impurities inside the dust collection box 1 is minimized. This prevents the dust and impurities inside the dust collection box 1 from being discharged into the atmosphere through the discharge hole 7 or the upper feed frame 6, thus improving the usability of the dust removal mechanism.

[0046] A dust removal method for treating steel slag, using a dust removal mechanism for treating steel slag as described above, includes the following steps:

[0047] Step 1: After the steel slag is introduced into the rotating frame 514, both drive motor 1 501 and drive motor 2 510 are started. Drive motor 1 501 and drive motor 2 510 rotate in opposite directions. During the rotation of the rotating frame 514, the hydraulic cylinder 509 is periodically adjusted to drive the push plate 506 to push the steel slag, so that it comes into contact with the scraper 516 rotating in the opposite direction. The scraper 516 scrapes off the dust and impurities on the outside of the steel slag. The impact force between the scraper 516 and the steel slag is relatively large. During the repeated operation of the scraper 516, the dust removal operation on the outside of the steel slag is achieved. The dust pump 2 502 is started. The dust pump 2 502 collects the scraped dust and impurities through the dust suction hole 2 517 on the top hollow dust suction plate 504 and introduces them into the dust collection box 4.

[0048] Step 2: After passing through the reverse scraping component 5, the steel slag falls into the disordered rod 907 along the guide frame 8. The drive motor 3 905 is started, and the drive motor 3 905 drives each disordered rod 907 to rotate the steel slag, so that the steel slag hits each curved impact rod 904. The impact accelerates the removal of dust and impurities from the outside of the steel slag.

[0049] Step 3: After the steel slag undergoes the dual dust removal operation of the reverse scraping component 5 and the random impact detachment component 9, the dust and impurities on the outside of the steel slag are removed. The dust suction pump 301 is started. The dust suction pump 301 collects the dust and impurities from top to bottom of the dust collection box 1 through the dust suction holes 305 on each through pipe 304, ensuring that the amount of dust and impurities inside the dust collection box 1 is minimized.

[0050] Step 4: After the steel slag has undergone dust removal treatment, it falls inside the dust removal box 1. During the fall, the steel slag first impacts each of the downward pressure buffer plates 1005, and the buffer spring rods 1006 below them achieve initial buffering. The remaining force of the steel slag impacts the conical guide frame 1001, and the shock-absorbing spring rods 1003 below the conical guide frame 1001 achieve secondary buffering, thereby ensuring that the steel slag can be smoothly discharged through the discharge hole 7.

7. A dust removal method for treating steel slag, using a dust removal mechanism for treating steel slag as described in claim 6, characterized in that, The dust removal method includes the following steps: Step 1: After the steel slag is introduced into the rotating frame (514), both drive motor 1 (501) and drive motor 2 (510) are started. Drive motor 1 (501) and drive motor 2 (510) rotate in opposite directions. During the rotation of the rotating frame (514), the hydraulic cylinder (509) is periodically adjusted to drive the push plate (506) to push the steel slag, so that it comes into contact with the scraper (516) rotating in the opposite direction. The scraper (516) scrapes off the dust and impurities on the outside of the steel slag. The scraper (516) in the opposite direction impacts the steel slag. During the repeated operation of the scraper (516), the dust removal operation on the outside of the steel slag is realized. The dust pump 2 (502) is started. The dust pump 2 (502) collects the scraped dust and impurities through the dust suction hole 2 (517) on the top hollow dust suction plate (504) and introduces them into the dust collection box (4). Step 2: After passing through the reverse scraping component (5), the steel slag falls into the disordered rod (907) along the guide frame (8). The drive motor three (905) is started. The drive motor three (905) drives each disordered rod (907) to rotate the steel slag, so that the steel slag hits each curved impact rod (904). The impact accelerates the removal of dust and impurities from the outside of the steel slag. Step 3: After the steel slag undergoes dual dust removal operations by the reverse scraping component (5) and the random impact detachment component (9), the dust and impurities on the outside of the steel slag are removed. The first dust pump (301) is started. The first dust pump (301) collects the dust and impurities from top to bottom of the dust collection box (1) through the dust suction holes (305) on each through pipe (304), ensuring that the amount of dust and impurities inside the dust collection box (1) is minimized. Step 4: After the steel slag has been treated by dust removal, it falls inside the dust removal box (1). During the fall, the steel slag first hits each of the downward pressure buffer plates (1005), and the buffer spring rod (1006) below it achieves initial buffering. The remaining force of the steel slag hits the conical guide frame (1001), and the shock-absorbing spring rod (1003) below the conical guide frame (1001) achieves secondary buffering, thereby ensuring that the steel slag is discharged smoothly along the discharge hole (7).
