Description

Technical Field

[0001] This application relates to the field of steel outlet cleaning technology, and in particular to a hydraulically driven steel outlet cleaning device and its positioning method. Background Technology

[0002] In steel containers (commonly ladles, electric arc furnace bodies, etc.), steel is typically tapped from the lower tapping port. After the tapping port is opened, the molten steel flows into the designated process. After the container finishes tapping, unmelted waste, slag, heavy residue, waste graphite blocks, etc., may clog the tapping port. When adding guiding sand to the tapping port during reuse, these substances can cause uneven filling of the sand, resulting in localized empty pipes. During the next smelting process, loose sand may fall out, potentially causing steel penetration accidents. Therefore, the tapping port needs to be cleaned before the next use, requiring the use of specialized cleaning equipment.

[0003] Patent CN114260267B discloses a cleaning device for the outlet of a molten steel container. This prior art avoids the possibility of slag and molten steel splashing and causing high-temperature damage due to manual close approach to the outlet for cleaning, shortens equipment downtime, improves work efficiency, and indirectly increases economic benefits.

[0004] However, the aforementioned existing technologies have the following technical defects: First, the existing technology simply relies on the cleaning rod to be moved inside the steel outlet to clean impurities. However, the diameter of the cleaning rod is smaller than the diameter of the steel outlet, so the cleaning rod cannot make complete contact with the inner wall of the outlet during the cleaning process, making it difficult to completely clean the impurities from the steel outlet.

[0005] Second, the impurities removed by this existing technology are not collected and are allowed to fall freely. This not only pollutes the environment when they fall into the workshop, but the free-falling impurities will also bounce off and spread everywhere, making later cleaning very troublesome. Furthermore, if they bounce off and hit the workers, the high-temperature impurities will burn them.

[0006] Therefore, existing technologies still have room for improvement in terms of enhancing the ability of devices to clean steel outlets and preventing impurities from rebounding everywhere. As a result, those skilled in the art have proposed a hydraulically driven steel outlet cleaning device and its positioning method. Summary of the Invention

[0007] To address the aforementioned problems, firstly, this application provides a hydraulically driven steel outlet cleaning device, employing the following technical solution: It includes a drive mechanism, which includes a hydraulic slewing arm with the drive end facing downward. A hydraulic telescopic arm is installed at the drive end of the hydraulic slewing arm, and a cantilever is installed at the lower end of the hydraulic telescopic arm.

[0008] A cleaning mechanism is installed at the end of the cantilever. The cleaning mechanism includes an L-shaped seat. A main rod facing upward is installed at the upper center of the L-shaped seat. Multiple sets of evenly distributed mounting seats are axially installed on the side of the main rod. Multiple mounting seats in each set are evenly installed on the side of the main rod in the circumferential direction. Each set of mounting seats is set with the same deflection angle as the previous set of mounting seats. A hook plate parallel to the main rod is hinged on the mounting seat. An electric cylinder is installed on the lower side of the L-shaped seat.

[0009] The cleaning mechanism also includes a deployment component.

[0010] It also includes a receiving mechanism, which includes a receiving box that is sleeved on the main rod and rotatably connected to the upper side of the L-shaped seat. One side of the receiving box is open. A fixed seat is installed on the telescopic arm of the electric cylinder. A connecting rod 2, whose upper end is hinged to the lower side of the receiving box, is hinged to the side of the fixed seat.

[0011] Preferably, the unfolding assembly includes a circular groove in the center of the main rod, an inner rod whose end is connected to the end of a telescopic arm of the electric cylinder is slidably disposed in the circular groove, and a frustum-shaped cleaning head with a lower surface diameter larger than the overall width of each set of hook plates is installed at the end of the main rod.

[0012] Preferably, a set of movable sleeves is slidably provided on one side of each set of hook plates on the surface of the main rod, and a connecting rod with the end hinged to the side of the corresponding movable sleeve is provided on both sides of the hook plate, and multiple evenly distributed protrusions are provided on the side of the hook plate near the main rod.

[0013] Preferably, the side of the main rod has a set of sliding grooves communicating with the circular groove on one side of each movable sleeve, and each sliding groove has a connecting block whose two ends are respectively connected to the corresponding movable sleeve and the inner rod.

[0014] Preferably, the receiving mechanism also includes two arc-shaped racks disposed on both sides of the receiving box, and a set of L-shaped frames fixedly connected to the L-shaped seat is installed on the side of the arc-shaped racks.

[0015] Preferably, a gear is rotatably mounted on both sides of the receiving box, meshing with an arc-shaped rack on the same side, and a straight rack is slidably disposed on the side of the receiving box, meshing with the gear on the same side.

[0016] Preferably, a baffle is hinged at the opening of the receiving box, and the hinge point is located on the upper edge of the baffle. A connecting frame is installed at one end of the straight rack near the baffle. A sliding groove is provided on the side of the connecting frame, and a sliding component connected to the baffle is slidably disposed in the sliding groove.

[0017] Preferably, a set of slide bars is installed on the side of the receiving box below each straight rack, and a slider connected to the straight rack on the same side is slidably arranged on each set of two slide bars.

[0018] Preferably, the drive mechanism also includes a hydraulic rod installed on the side of the hydraulic telescopic boom, with a pin installed at the lower end of the hydraulic rod, and a pin cylinder adapted to the pin installed on the side of the hydraulic boom. When the hydraulic boom drive rod is aligned with the steel outlet, the pin is aligned with the pin cylinder.

[0019] On the other hand, this application also discloses a positioning method for a hydraulically driven steel outlet cleaning device: the method includes the following steps: S1. Align the steel outlet by using a drive mechanism to align the cleaning mechanism with the steel outlet.

[0020] S2. Device positioning: Insert the pin into the pin cylinder to position the cantilever.

[0021] S3. Structure unfolding: Insert the main rod into the steel outlet and then unfold the hook plate.

[0022] S4. Impurity removal: The hydraulic telescopic arm extends to use the cleaning mechanism to remove impurities from the steel outlet.

[0024] In summary, this application includes at least one of the following beneficial technical effects: I. This application features a deployable cleaning mechanism. When the hook plates are not deployed, the cleaning mechanism can easily enter the steel outlet. Once fully inside the outlet, it is deployed. At this point, the overall width of each set of hook plates is the same as the diameter of the steel outlet. As the hook plates move out, they can hook off the impurities adhering to the steel outlet. Furthermore, the multiple sets of hook plates are evenly distributed circumferentially from a top view perspective. This allows all the impurities adhering to the inner wall of the steel outlet to be hooked off at once, reducing time consumption. Thus, this mechanism can clean most of the impurities in a single operation while ensuring complete cleaning of the impurities adhering to the steel outlet, thereby accelerating the cleaning efficiency.

[0025] Second, this application also includes a receiving mechanism. When cleaning impurities, the receiving mechanism collects the hooked impurities to prevent them from falling onto the workshop floor and bouncing back up, which would make them difficult to clean. It also prevents them from bouncing back onto workers, protecting their lives and safety and preventing contamination. Furthermore, by cooperating with the cleaning mechanism, the receiving box is tilted and its opening is opened during the closing of the hook plate by the cleaning mechanism, allowing the collected impurities to automatically slide from the tilted receiving box into the trash can, thus automatically cleaning the impurities in the receiving box and realizing the integration of impurity collection and disposal.

[0041] The following combination Figure 1 - Figure 13 The embodiments of this application will be described in detail.

[0042] This application discloses a hydraulically driven steel outlet cleaning device and its positioning method. The device features an expandable cleaning mechanism. When the hook plates are not fully expanded, the cleaning mechanism easily enters the steel outlet. Once fully inside, it expands, with each set of hook plates having the same overall width as the steel outlet diameter. This allows the hook plates to remove impurities adhering to the steel outlet during their removal. Furthermore, the multiple sets of hook plates are evenly distributed circumferentially from a top-view perspective, enabling the removal of all adhering impurities from the inner wall of the steel outlet in one go, reducing time consumption. This mechanism ensures complete cleaning of impurities adhering to the steel outlet while allowing for the removal of most impurities in a single operation, thus accelerating cleaning efficiency.

[0043] Example 1: like Figure 1 and Figure 2 As shown, the device includes a drive mechanism 1, which includes a hydraulic rotary arm 101 with the drive end facing downward. A hydraulic telescopic arm 102 is installed at the drive end of the hydraulic rotary arm 101, and a cantilever 103 is installed at the lower end of the hydraulic telescopic arm 102. A cleaning mechanism 2 is installed at the end of the cantilever 103. The device is installed at the steel outlet. Then, the hydraulic rotary arm 101 drives the hydraulic telescopic arm 102 to rotate. The cantilever 103 drives the cleaning mechanism 2 to align with the circular steel outlet. Then, the hydraulic telescopic arm 102 continues to extend and retract, and the cleaning mechanism 2 cleans the impurities adhering to the steel outlet.

[0044] like Figure 2 and Figure 3As shown, the drive mechanism 1 also includes a set of rectangular seats 104 installed on the side of the hydraulic telescopic arm 102. The two rectangular seats 104 in the set are jointly inserted with pins 105. A hydraulic rod 106 with its lower end connected to the pin 105 is installed on the side of the hydraulic telescopic arm 102 above the pin 105. A pin cylinder 107 adapted to the pin 105 is installed on the side of the hydraulic rotating arm 101. When the hydraulic rotating arm 101 drives the hydraulic telescopic arm 102 to rotate, it will also drive the pin 105 and the hydraulic rod 106 to move. When the cleaning mechanism 2 is aligned with the steel outlet, the pin 105 is aligned with the pin cylinder 107. Then the hydraulic rod 106 extends and drives the pin 105 to insert into the pin cylinder 107 to position the cantilever 103.

[0045] like Figure 2 and Figure 3 As shown, an infrared generator is mounted on the side of the hydraulic swivel arm 101, and an infrared receiver is mounted on the side of the hydraulic telescopic arm 102. A controller is also mounted on the hydraulic swivel arm 101. The controller is electrically connected to the hydraulic swivel arm 101, the hydraulic telescopic arm 102, the hydraulic rod 106, the infrared generator, and the infrared receiver. When the hydraulic swivel arm 101 drives the hydraulic telescopic arm 102 to rotate until the cleaning mechanism 2 is aligned with the steel outlet, the infrared generator is aligned with the infrared receiver. The infrared receiver receives the infrared light from the infrared generator and sends a signal to the controller, which then controls the hydraulic swivel arm 101 to close.

[0046] like Figures 4-6 As shown, the cleaning mechanism 2 includes an L-shaped seat 201. A main rod 203 facing upward is installed at the upper center of the L-shaped seat 201. A frustum-shaped cleaning head 210 is installed at the end of the main rod 203. The cleaning head 210 can squeeze out impurities from the inner wall of the steel outlet to ensure that the main rod 203 with components can be smoothly inserted into the steel outlet.

[0047] like Figure 6 and Figure 7 As shown, multiple sets of evenly distributed mounting seats 205 are axially installed on the side of the main rod 203. In each set, multiple mounting seats 205 are evenly installed circumferentially on the side of the main rod 203. The upper and side of the mounting seats 205 are provided with mounting grooves. Hook plates 206 parallel to the main rod 203 are hinged in the mounting grooves. The overall width of the four hook plates 206 in each set is smaller than the diameter of the lower surface of the cleaning head 210. Therefore, when the hook plates 206 are parallel to the main rod 203, they will not come into contact with impurities in the steel outlet when they enter the outlet. When the hook plates 206 are perpendicular to the main rod 203, the overall width of the hook plates 206 in the set is the same as the diameter of the outlet. The outwardly moving main rod 203 uses the hook plates 206 to hook out the impurities adhering to the outlet.

[0048] like Figures 6-8As shown, each set of hook plates 206 is set with a 15-degree deflection angle relative to the previous set of hook plates 206. The side of the hook plate 206 near the main rod 203 is provided with multiple evenly distributed protrusions 207. The 15-degree deflection angle allows the multiple sets of hook plates 206 to be evenly distributed circumferentially from the top view perspective and to cover the inner wall of the steel outlet without any dead angles. In this way, multiple sets of hook plates 206 can be used to hook out a large number of impurities adhering to the inner wall of the steel outlet at once. The protrusions 207 can increase the friction coefficient of the side of the hook plate 206.

[0049] like Figure 6 and Figure 8 As shown, a U-shaped frame 204 is installed on the lower side of the L-shaped base 201, and an electric cylinder 202 is installed on the lower side of the U-shaped frame 204. A circular groove is opened in the center of the main rod 203. An inner rod 211 with its end connected to the end of the telescopic arm of the electric cylinder 202 is slidably arranged in the circular groove. During the extension and retraction of the electric cylinder 202, the inner rod 211 is driven to slide in the circular groove.

[0050] like Figure 7 and Figure 8 As shown, a set of movable sleeves 209 are slidably disposed on one side of each set of hook plates 206 on the surface of the main rod 203. Both sides of the hook plate 206 are hinged with connecting rods 208 whose ends are hinged to the sides of the corresponding movable sleeves 209. When the movable sleeves 209 move closer to the hook plates 206, they drive the hook plates 206 to deflect around the hinge point with the mounting base 205 through the connecting rods 208 until they are perpendicular to the main rod 203. When the movable sleeves 209 move in the opposite direction, they drive the hook plates 206 to deflect in the opposite direction and become parallel to the main rod 203.

[0051] like Figure 8 As shown, the side of the main rod 203 has a set of sliding grooves 212 connected to the circular groove on one side of each movable sleeve 209. Each sliding groove 212 has a connecting block 213 with its two ends connected to the corresponding movable sleeve 209 and the inner rod 211 respectively. The extended electric cylinder 202 drives the inner rod 211 to move, and the main rod 203 drives the movable sleeve 209 to move toward the hook plate 206. When the hook plate 206 is perpendicular to the main rod 203, the movable sleeve 209 covers the corresponding sliding groove 212 to prevent impurity particles from entering it. When the electric cylinder 202 shortens, it also drives the inner rod 211 and the movable sleeve 209 to move in the opposite direction.

[0052] In summary, the hydraulic boom 101 operates until the main rod 203 is aligned with the steel outlet. Then, the hydraulic rod 106 extends, causing the pin 105 to insert into the pin cylinder 107, positioning the cantilever 103. Next, the hydraulic telescopic boom 102 shortens, inserting the main rod 203 into the steel outlet until all hook plates 206 are in place. Then, the electric cylinder 202 extends, moving the inner rod 211 towards the cleaning head 210, and also moving each moving sleeve 209 towards its corresponding hook plate 206. The connecting rod 208 deflects the hook plate 206. When the inner rod 21... When the end of the device moves to the end of the circular groove, the hook plate 206 is exactly at a 90-degree angle to the main rod 203. Then, the hydraulic telescopic arm 102 extends and drives the main rod 203 to move out of the steel outlet. Multiple sets of hook plates 206 are used to hook out the impurities adhering to the inner wall of the steel outlet. When all the hook plates 206 have been moved out, the electric cylinder 1 202 shortens and drives the hook plates 206 to deflect in the opposite direction. When it is shortened to the shortest length, the hook plates 206 are exactly parallel to the main rod 203. The staff observes the cleaning of impurities at the steel outlet. If there are still residues, the device repeats the above operation until the impurities are completely cleaned.

[0053] like Figure 4 , Figure 5 and 10 As shown, it also includes a receiving mechanism 3, which includes a receiving box 301 that is sleeved on the main rod 203 and rotatably connected to the upper side of the L-shaped seat 201. One side of the receiving box 301 is open. A fixed seat 303 is installed on the telescopic arm of the electric cylinder 202. A connecting rod 304 is hinged to the side of the fixed seat 303, and its upper end is hinged to the lower side of the receiving box 301. The hooked impurities fall into the receiving box 301 for collection. Then, during the shortening process of the electric cylinder 202, the fixed seat 303 will also be driven to descend. The connecting rod 304 pulls the receiving box 301 to deflect around the rotatable connection, so that the opening tilts downward and the garbage bin is placed in the opening position. Then the collected impurities slide into the garbage bin from the opening, thus achieving cleaning.

[0054] like Figure 10 and Figure 11 As shown, a through hole 313 is provided at the center of the upper side of the receiving box 301 for the main rod 203 to pass through. A high-temperature resistant metal rubber ring is filled between the through hole 313 and the main rod 203. A high-temperature resistant metal rubber pad is laid on the upper side of the receiving box 301. The high-temperature resistant metal rubber ring is used to prevent impurities from leaking out of the gap between the through hole 313 and the main rod 203. At the same time, its flexibility also makes it easy for the receiving box 301 to change its shape when tilted. The high-temperature resistant metal rubber pad can dampen the impurities falling into the receiving box 301 and prevent them from rebounding and flying out of the receiving box 301.

[0055] like Figure 10As shown, an arc-shaped rack 305 is provided on both sides of the receiving box 301. A set of L-shaped brackets 306 fixedly connected to the L-shaped seat 201 is installed on the side of the arc-shaped rack 305. Gears 307 that mesh with the arc-shaped racks 305 on the same side are rotatably installed on both sides of the receiving box 301. A straight rack 308 that meshes with the gears 307 on the same side is slidably provided on the side of the receiving box 301. When the receiving box 301 is tilted, it will also drive the gears 307 to move. The arc-shaped racks 305 cause the gears 307 to rotate during the movement. The rotating straight rack 308 moves in the direction of the opening, and vice versa.

[0056] like Figure 10 As shown, a baffle 302 is hinged at the opening of the receiving box 301, and the hinge point is located on the upper edge of the baffle 302. A connecting frame 309 is installed at the end of the straight rack 308 near the baffle 302. A sliding groove is provided on the side of the connecting frame 309, and a sliding member 310 connected to the baffle 302 is slidably disposed in the sliding groove. When the straight rack 308 moves in the direction of the opening, it drives the connecting frame 309 to move in the same direction. The sliding member 310 pushes the baffle 302 to deflect around the rotating connection point, so that the opening opens and facilitates the discharge of impurities. At the same time, the sliding member 310 also slides in the sliding groove. When the straight rack 308 moves in the opposite direction, it drives the baffle 302 to deflect in the opposite direction and close the opening.

[0057] like Figure 10 As shown, a set of slide bars 311 is installed on the side of the receiving box 301 below each straight rack 308. A slider 312 connected to the straight rack 308 on the same side is slidably arranged on each set of two slide bars 311. The moving straight rack 308 drives the slider 312 to slide on the slide bar 311, which enhances the stability of the straight rack 308 when it moves.

[0058] It should be noted that both sides of the receiving box 301 are provided with dust covers that together wrap around the arc-shaped rack 305, gear 307, and straight rack 308 to prevent impurities from falling on them and causing jamming. At the same time, the slide rod 311 and the inside of the slide groove are coated with a smooth layer to ensure that the slider 312 slides normally on the slide rod 311 and the slider 310 slides normally in the slide groove without jamming.

[0059] Meanwhile, the cleaning mechanism uses the deflection of the receiving box 301 and the gear transmission principle to deflect the baffle 302 to open the opening. Since the cleaning mechanism needs to frequently enter the steel outlet, the electric cylinder 202 needs to frequently extend and retract to open and close the cleaning mechanism, which in turn causes the receiving box 301 to tilt frequently. The gear transmission has no elastic delay and is more suitable for this high-frequency action. Moreover, as long as the gear transmission is well lubricated, its wear is slow and its service life is long. At the same time, it only needs to be lubricated periodically, making maintenance simple.

[0060] In summary, after the hook plate 206 hooks out the impurities adhering to the steel outlet, the impurities fall freely into the collection box 301 for collection. During the closing process of the hook plate 206 being completely removed, the waste bin is placed below the opening of the collection box 301. The retracting electric cylinder 202 also causes the fixed base 303 to descend, pulling the collection box 301 around the rotating connection point via the connecting rod 304, causing the opening to tilt downwards. The tilting of the collection box 301 also drives the gear 307 to move, which in turn moves the arc-shaped rack 3... 05. Gear 307 rotates during movement, and the rotating straight rack 308 moves towards the opening. The moving straight rack 308 drives the connecting frame 309 to move in the same direction. Through the slider 310, the baffle 302 is pushed to deflect around the rotating connection, opening the opening. Then, the impurities in the tilted collection box 301 slide into the garbage bin from the opening. When the electric cylinder 202 extends, it will also drive the collection box 301 to deflect in the opposite direction to return to its original position, and the baffle 302 will close the opening again.

[0061] Example 2: Based on Example 1, such as Figure 11 and Figure 13 As shown, it also includes a guiding mechanism 4, which includes two guide plates 401 symmetrically arranged inside the receiving box 301 and in close contact with its inner wall. The ends of the guide plates 401 away from the baffle 302 are hinged to the inner wall of the receiving box 301, allowing the two guide plates 401 to deflect around the hinge, tilting the two guide plates 401 and bringing the ends near the opening closer to each other until the distance between the two ends is the same as the width of the top opening of the garbage bin. Then, the two guide plates 401 can be used to guide the impurities in the receiving box 301, allowing the impurities to enter the garbage bin accurately, making the device compatible with various models of garbage bins.

[0062] like Figure 12 As shown, a gear 404 is rotatably mounted on the lower side of the receiving box 301. Two straight racks 405 are arranged around the gear 404 and are slidably connected to the lower side of the receiving box 301. An electric cylinder 406 is installed on the lower side of the receiving box 301, with the end of the telescopic arm connected to one of the straight racks 405. The electric cylinder 406 extends and drives the straight rack 405 connected to it to move. Then, the gear 404 drives the other straight rack 405 to move in the opposite direction, so that the two straight racks 405 move towards each other, and vice versa.

[0063] like Figure 11 and Figure 12As shown, the side of the receiving box 301 has a groove on one side of each guide plate 401. A crossbar 402 is installed on the side of the guide plate 401 in the groove on the same side. A slide block 403 is slidably arranged on the crossbar 402. A connecting frame 407 is installed at the end of the straight rack 405. One end of the connecting frame 407 is rotatably connected to the slide block 403 on the same side. The two straight racks 405 moving in opposite directions drive the two connecting frames 407 to move closer to each other. Then, the slide block 403 pushes the guide plate 401 on the same side to deflect. At the same time, it also drives the slide block 403 to slide on the baffle 302. When the electric cylinder 406 shortens and the two straight racks 405 move in opposite directions, it drives the two connecting frames 407 to move away from each other. It also drives the guide plate 401 to deflect in the opposite direction.

[0064] In summary, when the garbage bin is placed at the opening of the receiving box 301, the electric cylinder 406 extends, causing the connected straight rack 405 to move. Then, the gear 404 drives another straight rack 405 to move in the opposite direction, causing the two straight racks 405 to move towards each other. This causes the two connecting frames 407 to move closer together, and then the slide 403 pushes the guide plate 401 on the same side to deflect until the distance between the two ends is the same as the width of the top opening of the garbage bin. Then, the two guide plates 401 can be used to guide the impurities in the receiving box 301, allowing the impurities to enter the garbage bin accurately. This allows the device to be adapted to garbage bins with various top opening widths.

[0065] This application also discloses a positioning method for a hydraulically driven steel outlet cleaning device, the steps of which are as follows: S1. Align the steel outlet. The cleaning mechanism 2 is aligned with the steel outlet by the drive mechanism 1. Specifically, the hydraulic swivel arm 101 drives the hydraulic telescopic arm 102 and the cantilever 103 to rotate and move the cleaning mechanism 2. When the cleaning mechanism 2 is aligned with the steel outlet, the infrared generator is aligned with the infrared receiver. The infrared receiver receives the infrared light from the infrared generator and sends a signal to the controller. The controller controls the hydraulic swivel arm 101 to close.

[0066] S2. Device positioning: Insert the pin 105 into the pin cylinder 107 to position the cantilever 103. Specifically, when the hydraulic telescopic arm 102 rotates, it will also drive the pin 105 to rotate. When the cleaning mechanism 2 is aligned with the steel outlet, the pin 105 is aligned with the pin cylinder 107. Then, the hydraulic rod 106 extends and drives the pin 105 to descend and insert into the pin cylinder 107 to position the cantilever 103.

[0067] S3. The structure unfolds. After inserting the main rod 203 into the steel outlet, the hook plates 206 unfold. Specifically, the hydraulic telescopic arm 102 shortens the main rod 203 into the steel outlet until all hook plates 206 are in. Then, the electric cylinder 202 extends and moves the inner rod 211 toward the cleaning head 210, and also moves each moving sleeve 209 toward the corresponding hook plate 206. The hook plate 206 is deflected by the connecting rod 208. When the end of the inner rod 211 moves to the end of the circular groove, the hook plate 206 is exactly at a 90-degree angle to the main rod 203.

[0068] S4. Impurity Cleaning: The hydraulic telescopic arm 102 extends to clean impurities at the steel outlet using the cleaning mechanism 2. Specifically, the extension of the hydraulic telescopic arm 102 drives the main rod 203 to move out of the steel outlet. Multiple sets of hook plates 206 hook out the impurities adhering to the inner wall of the steel outlet. When all hook plates 206 have been moved out, the electric cylinder 1 202 shortens, causing the hook plates 206 to deflect in the opposite direction. When it is at its shortest length, the hook plates 206 are exactly parallel to the main rod 203. The operator observes the cleaning of impurities at the steel outlet. If there are still residues, the device repeats the above operation until the impurities are completely cleaned.

[0069] S5. Impurity Collection: The collecting mechanism 3 collects the hooked-out impurities. During the shortening of the electric cylinder 202, the collecting mechanism 3 is cleaned of impurities. Specifically, after the hook plate 206 hooks out the impurities adhering to the steel outlet, the impurities fall freely into the collecting box 301 for collection. When the hook plate 206 is completely removed and closed, the waste bin is placed below the opening of the collecting box 301. The retracting electric cylinder 202 also causes the fixed base 303 to descend, pulling the collecting box 301 around the rotating connection point via the connecting rod 304, causing the opening to tilt downwards. When the receiving box 301 tilts, it also drives the gear 307 to move. The arc rack 305 causes the gear 307 to rotate during the movement. The rotating straight rack 308 moves towards the opening. The moving straight rack 308 drives the connecting frame 309 to move in the same direction. The slider 310 pushes the baffle 302 to deflect around the rotating connection, opening the opening. Then, the impurities in the tilted receiving box 301 slide into the garbage bin from the opening. When the electric cylinder 202 extends, it also drives the receiving box 301 to return to its original position and causes the baffle 302 to close the opening again.
