Description

Technical Field

[0001] This application relates to the field of dephosphorization of wire rod, and in particular to an environmentally friendly dephosphorization machine for whole coil wire rod. Background Technology

[0002] During the production or storage of wire rods, impurities such as phosphorus oxide scale often accumulate on their surface. If not treated promptly, this can lead to pitting on the wire rod surface, severely affecting its quality. A descaling machine is specifically designed to remove phosphorus oxide scale from the surface of wire rods.

[0003] Related technologies disclose equipment for descaling entire coils of wire rod. This equipment mainly includes a descaling chamber, a rotatable rotating door on one side of the chamber, a horizontally rotatable cantilever mounted on the rotating door, and multiple shot throwers located within the descaling chamber for projecting steel shot towards the rotating door. During operation, the entire coil of wire rod to be descaled is stretched into a long coil and suspended from the cantilever. The rotating door then rotates, causing the entire coil to rotate into the descaling chamber. Simultaneously, the rotating door closes the descaling chamber. Then, the rotating cantilever rotates, causing the entire coil to rotate. As the cantilever rotates, the multiple shot throwers project steel shot onto the entire coil, striking it and achieving descaling of the entire coil.

[0004] However, when using the aforementioned technology to perform dephosphorization of whole coils of wire rod, a significant problem was found: the surface facing the direction of the thrower was often better at dephosphorization, while the surface in the other direction was slightly worse. This resulted in uneven dephosphorization of the whole coil, making it difficult to guarantee the quality of dephosphorization of the whole coil. Summary of the Invention

[0005] In order to achieve uniform dephosphorization of the entire coil of wire rod and improve the dephosphorization quality of the entire coil of wire rod, this application provides an environmentally friendly dephosphorization machine for the entire coil of wire rod.

[0006] This application provides an environmentally friendly descaling machine for whole coil wire rods, which adopts the following technical solution: An environmentally friendly descaling machine for whole coils of wire rod includes: Phosphorus removal chamber; A revolving door, rotatably mounted on one side of the dephosphorization chamber, can open or close the chamber. A cantilever, horizontally rotatable, is installed on at least one side of the revolving door; Multiple forward and reverse-rotating projectiles are located on the same plane and surround the revolving door on three sides in the descaling chamber, used to project steel shot towards the revolving door.

[0007] By adopting the above technical solution, during operation, the entire coil of wire rod to be dephosphorized is stretched and extended into a long coil shape and suspended on a cantilever. Then, the rotating door rotates, driving the entire coil of wire rod to rotate into the dephosphorization chamber. At the same time, the rotating door also closes the dephosphorization chamber. Then, the rotating cantilever rotates, driving the entire coil of wire rod to rotate. At this time, the shot throwers, which are set on the same plane and surround the rotating door on three sides, will achieve three-sided coverage of the entire coil of wire rod suspended on the rotating door cantilever. Since each shot thrower can achieve forward and reverse rotation, the direction of its shot throwing can be changed. In this way, multiple shot throwers surrounding the entire coil of wire rod on three sides, together with the ability to throw steel shot in both forward and reverse directions, can achieve full coverage dephosphorization of the entire coil of wire rod during the rotation of the entire coil of wire rod on the cantilever, achieving uniform dephosphorization of the entire coil of wire rod and improving the dephosphorization quality of the entire coil of wire rod.

[0008] Optional, also includes: The drive module is used to drive each launcher to rotate forward and backward. The timing module is used to preset the time period and send a signal when the time period arrives; The control module receives signals from the timing module and controls the drive module to switch between forward and reverse rotation for each launcher.

[0009] By adopting the above technical solution, during operation, the timing module and the control module work together to enable the drive module to control the throwing device to rotate forward and backward after a certain period of time, thereby changing the throwing direction of the throwing device and achieving full impact on the entire coil of wire rod to complete the descaling operation.

[0010] Optional, also includes: The material collection trough is located below the phosphorus removal chamber and is connected to the phosphorus removal chamber. The screw conveyor is horizontally installed in the trough to collect the steel shot in the trough to one side of the trough. The elevator is vertically installed on one side of the descaling chamber and is used to transport the steel shot collected in the trough upwards. The sand separation chamber, located above the descaling chamber, is used to receive the steel sand lifted by the hoist and separate it before sending it to each throwing device.

[0011] By adopting the above technical solution, when the thrower throws steel shot onto the coil of wire rod, it will fall directly into the accumulation trough. Then, the screw conveyor can send the steel shot in the accumulation trough to the elevator position. The elevator can directly lift the steel shot upward and send it to the sand and debris separation chamber. After the lifted steel shot is sent to the sand and debris separation chamber, the steel shot will be separated from other impurities and debris. Then, the separated steel shot can enter the thrower to continue the descaling operation, realizing the cycle.

[0012] Optionally, the sand separation chamber includes: silos; The feeding cylinder is horizontally fixed to the vertical side of the hopper and is used to connect with the elevator; The screw feeder is coaxially mounted inside the feeding cylinder, with one end extending into the hopper. A mesh cylinder is fixed inside the hopper and coaxially sleeved on the outside of the screw conveyor. The mesh aperture of the mesh cylinder is not less than the diameter of the steel shot and less than twice the diameter of the steel shot. A guide plate is fixed inside the hopper along the length of the mesh cylinder, and the guide plate is inclined to the horizontal plane; A sand discharge trough is located below the guide plate corresponding to the hopper, and a chip extraction zone is formed between the sand discharge trough and the guide plate; The dust extraction unit, connected to the hopper, is used to remove impurities from the chip extraction area.

[0013] By adopting the above technical solution, during operation, after the steel shot enters the feed cylinder, the screw feeder transports the steel shot and waste chips to the mesh cylinder inside the hopper. As the steel shot and waste chips are transported to the mesh cylinder, they can flow down through the mesh holes. Since the mesh cylinder's aperture allows one steel shot to flow out, the steel shot will flow in a relatively uniform curtain-like manner onto the guide plate. Then, the steel shot is buffered and guided by the guide plate before falling from the chip extraction area into the sand discharge trough. During this process, the dust extraction component can remove the waste chips from the chip extraction area. Furthermore, because the chip extraction area is relatively small, the airflow velocity when passing through the chip extraction area can be increased, thereby increasing the negative pressure suction and ensuring complete chip extraction.

[0014] Optionally, the guide plate includes: An inclined plate is fixed to the lower side of the corresponding material cylinder in the hopper. A horizontal plate is fixed to the lower end of the inclined plate.

[0015] By adopting the above technical solution, after the steel shot falls from the mesh cylinder, it will first fall onto the inclined plate for the first buffering and dispersion. Then, with the flow of the steel shot, it will fall onto the horizontal plate for the second buffering. After falling, it will pass through the chip extraction zone and finally fall into the discharge chute, reducing the impact potential energy of the steel shot and ensuring that the waste chips in the steel shot can be completely extracted.

[0016] Optionally, a first baffle is provided on the upper side of the guide plate corresponding to the hopper; A first material drop gap is formed between the first baffle and the guide plate, and the height of the first material drop gap is the same as the diameter of the steel shot.

[0017] By adopting the above technical solution, the first baffle and the guide plate can be used together to further realize the curtain-like distribution of steel shot, thereby limiting the amount of steel shot falling from the chip extraction area at the same time, so as to facilitate the complete extraction of impurities in the steel shot.

[0018] Optionally, a second baffle is vertically provided above the lower end of the guide plate corresponding to the hopper; A second material discharge gap is formed between the second baffle and the guide plate, and the distance of the second material discharge gap is not less than the diameter of the steel shot and less than twice the diameter of the steel shot; The second baffle is equipped with a vibration element.

[0019] By adopting the above technical solution, the second material drop gap left between the second baffle and the lower end of the guide plate can make the steel sand flow down evenly, ensuring the discharge of waste. Moreover, due to the vibration element, the second baffle can vibrate, avoiding steel sand blockage and ensuring the smooth flow of steel sand.

[0020] Optionally, a drive component is fixed to one end of each cantilever of the revolving door to drive the cantilever to rotate in both directions; A protective cover is fixed to the outside of the drive component of the revolving door to protect the drive component.

[0021] By adopting the above technical solution, during operation, the drive component can drive the rotating arm to rotate in both directions, thereby achieving descaling of the entire coil of wire rod, while the protective cover can effectively prevent damage to the drive component.

[0022] Optionally, the revolving door is provided with an arc-shaped rebound pad corresponding to the cantilever; The revolving door is surrounded by multiple layers of plastic curtains along its thickness direction.

[0023] By adopting the above technical solution, the arc-shaped rebound pad can effectively rebound the steel sand ejected onto the revolving door, so that the steel sand can hit the coiled wire rod on the cantilever again for descaling. The multi-layered rubber curtain can effectively prevent the steel sand from being ejected between the revolving door and the descaling chamber after the revolving door is closed, thus avoiding leakage of steel sand.

[0024] In summary, this application includes at least one of the following beneficial technical effects: During operation, the entire coil of wire rod to be dephosphorized is stretched into a long coil and suspended from the cantilever. Then, the rotating door drives the entire coil of wire rod to rotate into the dephosphorization chamber. At the same time, the rotating door also closes the dephosphorization chamber. Then, the rotating cantilever drives the entire coil of wire rod to rotate. At this time, the shot throwers, which are set in the same plane and surround the rotating door on three sides, will achieve three-sided coverage of the entire coil of wire rod suspended on the rotating door cantilever. Since each shot thrower can be rotated in both directions, the direction of its shot throwing can be changed. In this way, multiple shot throwers surrounding the entire coil of wire rod on three sides, together with the ability to throw steel shot in both directions, can achieve full coverage dephosphorization of the entire coil of wire rod during the rotation of the entire coil of wire rod on the cantilever, achieving uniform dephosphorization of the entire coil of wire rod and improving the dephosphorization quality of the entire coil of wire rod.

[0025] By coordinating the timing module and the control module, the thrower can be controlled to rotate forward and backward after a certain period of time via the drive module. This changes the direction of the thrower's sand-throwing, ensuring thorough impact on the entire coil of wire rod to complete the descaling operation.

[0026] During operation, after the steel shot enters the feed cylinder, the screw feeder transports the steel shot and waste chips to the mesh cylinder inside the hopper. As the steel shot and waste chips are transported into the mesh cylinder, they can flow down through the mesh holes. Since the mesh cylinder's aperture allows one steel shot to flow out at a time, the steel shot will flow in a relatively uniform curtain-like manner onto the guide plate. Then, the steel shot is buffered and guided by the guide plate before falling from the chip extraction zone into the sand discharge trough. During this process, the dust extraction component can remove the waste chips from the chip extraction zone. Furthermore, because the chip extraction zone is relatively small, it can increase the airflow velocity when passing through the chip extraction zone, thereby increasing the negative pressure suction and ensuring complete chip extraction.

[0029] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0030] This application discloses an environmentally friendly dephosphorization machine for whole coil wire rods.

[0031] Example 1: Reference Figure 1 An environmentally friendly descaling machine for whole coil wire rod includes: a descaling chamber 1, a material accumulation trough 2 disposed on the lower side of the descaling chamber 1, a sand and debris separation chamber 3 disposed on the upper side of the descaling chamber 1, and a hoist 4 disposed on the rear side of the descaling chamber 1 and connecting the material accumulation trough 2 and the sand and debris separation chamber 3.

[0032] Reference Figure 1 During the dephosphorization operation, the entire coil of wire rod is placed in the dephosphorization chamber 1 for dephosphorization. The steel shot and wire rod scale thrown during the dephosphorization operation will fall into the accumulation trough 2. Then, the steel shot and wire rod scale will be lifted together by the elevator 4 to the sand and debris separation chamber 3. The steel shot and wire rod scale and other waste debris will be separated in the sand and debris separation chamber 3. Then, the steel shot will be put back into the dephosphorization chamber 1 for recycling.

[0033] Reference Figure 1 Specifically, the dephosphorization chamber 1 has a box-like structure. A feed inlet is vertically formed on one side along the length of the chamber. A rotating door 11 is located at the feed inlet, and the rotating door 11 is the same size as the feed inlet. A rotating shaft 111 is vertically fixed in the middle of the rotating door 11 along its length. Both ends of the rotating shaft 111 extend from the rotating door 11 and are rotatably connected to the dephosphorization chamber 1. A rotating element is also fixed above the rotating door 11 in the dephosphorization chamber 1. This rotating element can be a servo motor, stepper motor, or other component capable of driving the rotating shaft 111 to rotate. Thus, by rotating the rotating door 11, the feed inlet can be opened or closed via the rotating door 11.

[0034] Reference Figure 1 To further improve the sealing performance of the descaling chamber 1 and the rotating door 11, multiple layers of rubber curtains 112 can be fixed around the periphery of the rotating door 11. The rubber curtains 112 are all made of wear-resistant rubber and are arranged along the thickness direction of the rotating door 11. The multiple layers of rubber curtains 112 are staggered. In this way, when the feed inlet of the descaling chamber 1 is closed by the rotating door 11, the multiple layers of rubber curtains 112 can effectively seal the periphery of the descaling chamber 1 and the rotating door 11 to prevent steel shot from being ejected between the rotating door 11 and the descaling chamber 1.

[0035] Reference Figure 1 Both vertical sides of the revolving door 11 are provided with cantilever arms 12 along their length direction, and the length direction of the cantilever arms 12 is the same as that of the revolving door 11. A drive element, such as a reciprocating motor, is fixed to one end of the revolving door 11 corresponding to the cantilever arm 12. A protective cover 13 is also provided on the outside of the drive element of the revolving door 11 to protect the drive element.

[0036] During operation, the entire coil of wire rod is placed on the cantilever 12 and stretched appropriately so that the entire coil of wire rod fully covers the cantilever 12. After the entire coil of wire rod is fixed in the cantilever 12, the cantilever 12 containing the wire rod is rotated into the descaling chamber 1 by the rotating door 11. Then, the cantilever 12 is rotated by the drive element, which can drive the entire coil of wire rod to rotate in the forward or reverse direction to facilitate the descaling operation of the wire rod.

[0037] In another embodiment of this application, the cantilever 12 may also be configured as follows: Reference Figure 2 The cantilever 12 is formed by two sets of disc-shaped bodies 121 with multiple axes offset from each other. Both sets of disc-shaped bodies 121 are fixed at intervals along the axial direction of the cantilever 12, and a partition disc 122 protruding from the two sets of disc-shaped lifting surfaces is fixed between adjacent disc-shaped bodies 121. Both ends of the cantilever 12 are also fixed with a baffle 123 with a diameter larger than the diameter of the partition disc 122.

[0038] Thus, after the entire coil of wire is extended and fitted onto the cantilever 12, the multiple dividing discs 122 can prevent the entire coil of wire from retracting along its axial direction, and the baffle 123 prevents the wire from detaching from the cantilever 12. Furthermore, during rotation, the misaligned discs 121 keep the wire separated and improve the descaling effect of the wire by rising and falling.

[0039] The dephosphorization chamber 1 is equipped with multiple projectiles 14 located on the same plane. The axes of each projectile 14 are vertically arranged, and the multiple projectiles 14 surround the rotating door 11 on three sides, for projecting steel shot toward the cantilever 12 of the rotating door 11.

[0040] Reference Figure 3Specifically, the throwing device 14 includes a first throwing device 14 and a second throwing device 14. Four first throwing devices 14 are arranged along the length of the cantilever 12 within the descaling chamber 1. Similarly, four second throwing devices 14 are arranged in pairs, opposite each other, at positions corresponding to the two ends of the cantilever 12 within the descaling chamber 1. The arrangement direction of the two second throwing devices at the same end of the cantilever 12 is inclined to the axial direction of the cantilever 12, thus forming an arc-like shape facing the cantilever 12. A throwing motor 141 is fixed at one end of the axial direction of each throwing device 14 within the descaling chamber 1, used to drive the throwing device 14 to rotate intermittently in both forward and reverse directions, thereby throwing steel shot.

[0041] Reference Figure 1 Above the dephosphorization chamber 1, there is also a shot chamber 15, which is connected to the dephosphorization chamber 1 and is used to store steel shot and send the steel shot to multiple throwers 14.

[0042] In this way, after the steel shot is fed into the shot chamber 15 into the thrower 14, it can be thrown onto the rotating wire rod on the cantilever 12 by the thrower motor 141, thereby achieving descaling on the surface of the wire rod. In addition, since the multiple throwers 14 surround the cantilever 12 on three sides and each thrower 14 can achieve forward and reverse rotation, the direction of its steel shot can be changed. In this way, the entire coil of wire rod can be fully covered and uniformly descaled during the rotation of the wire rod.

[0043] Furthermore, in another embodiment of this application, the control components for the forward and reverse rotation of the launcher 14 are described in detail below: Reference Figure 4 The control components mainly include a drive module, a timing module, and a control module. The drive module is the throwing motor 141. The timing module and control module are integrated into the controller and electrically connected to the throwing motor 141. The timing module is used to preset a time period and send a signal when the time period arrives. The control module receives the signal from the timing module and controls the drive module to switch the forward and reverse rotation of each throwing device 14. Thus, through the cooperation of the timing module and the control module, the throwing devices 14 can be controlled to rotate forward and reverse after a certain period of time, thereby changing the throwing direction of the throwing devices 14 and achieving sufficient impact on the entire coil of wire rod to complete the descaling operation.

[0044] Reference Figure 1 and Figure 5The collection trough 2 is located below the descaling chamber 1 and is connected to the descaling chamber 1. In actual construction, the collection trough 2 can be installed underground. There are two collection troughs 2, which are arranged side by side below the descaling chamber 1 along its length. The length of both collection troughs 2 is perpendicular to the length of the descaling chamber 1, and the cross-section of both collection troughs 2 is V-shaped. A screw conveyor 21 is installed on the bottom surface of each collection trough 2 along its length. The screw conveyor 21 is used to deliver steel shot to one end of the collection trough 2.

[0045] Reference Figure 1 and Figure 5 There are two sand and dust separation chambers 3, located on both sides above the descaling chamber 1. The lower ends of the sand and dust separation chambers 3 are connected to the sand shot chamber 15 on the same side. The elevator 4 is vertically fixed to the rear side of the descaling chamber 1. The lower end of the elevator 4 is connected to the screw conveyor 21 of the material accumulation trough 2, and the upper end of the elevator 4 is connected to the sand and dust separation chamber 3. When the thrower 14 throws steel shot onto the whole coil of wire rod, it will fall directly into the material accumulation trough 2. Then, the screw conveyor 21 can send the steel shot in the material accumulation trough 2 to the elevator 4. The elevator 4 can then directly lift the steel shot upward and send it to the sand and dust separation chamber 3. After the lifted steel shot is sent to the sand and dust separation chamber 3, the steel shot will be separated from other impurities and debris. Then, the separated steel shot can enter the thrower 14 to continue the descaling operation, realizing a cycle.

[0046] In another embodiment of this application, a specific structure of a sand separation chamber 3 is provided, which will be described in detail below.

[0047] Reference Figure 6 The sand and dust separation chamber 3 includes a hopper 31. A feeding cylinder 32 is horizontally fixed to the upper vertical side of the hopper 31. The feeding cylinder 32 is connected to the upper end of the elevator 4, and a screw feeder 33 is coaxially arranged inside the feeding cylinder 32. One end of the screw feeder 33 passes through the feeding cylinder 32 and extends into the hopper 31. A mesh cylinder 34 is coaxially fixed inside the hopper 31 corresponding to the outer side of the screw feeder 32. The mesh cylinder 34 is made of metal such as stainless steel. The mesh aperture of the mesh cylinder 34 is not less than the diameter of the steel sand and less than twice the diameter of the steel sand. Preferably, the mesh aperture of the mesh cylinder 34 is the same as the diameter of the steel sand.

[0048] Reference Figure 6 A guide plate 35 is fixed on the lower side of the corresponding mesh cylinder 34 of the hopper 31. The guide plate 35 is inclined to the horizontal plane. Specifically, the guide plate 35 includes an inclined plate 351 located below the material cylinder and extending downward at its lower end, and a horizontal plate 352 fixed to the lower end of the inclined plate 351.

[0049] Reference Figure 6The lower end of the guide plate 35 corresponding to the hopper 31 is formed with a sand discharge groove 36, which is used to communicate with the sand shot chamber 15. A certain distance is formed between the upper side of the sand discharge groove 36 and the lower end of the guide plate 35, which serves as the chip extraction zone 361. A dust extraction pipe is provided on the rear side of the hopper 31, and a dust extraction component 5, such as a pulse dust collector, is also fixed on the rear side of the dephosphorization chamber 1.

[0050] Reference Figure 6 During operation, after the steel shot enters the feed cylinder, the screw feeder 33 transports the steel shot to the mesh cylinder 34 inside the hopper 31. Then, the waste and steel shot are discharged simultaneously through the mesh holes. Since the mesh cylinder 34 only allows one steel shot to flow out at a time, the steel shot can flow in a curtain-like form onto the guide plate 35. After being buffered and guided by the guide plate 35, the steel shot falls from the chip extraction zone 361 into the sand discharge trough 36. During this process, the dust extraction component 5 can remove the waste from the chip extraction zone 361. Since the chip extraction zone 361 is small, the airflow velocity when passing through the chip extraction zone 361 can be increased, and the negative pressure suction can be increased to ensure the removal of waste from the steel shot.

[0051] Reference Figure 6 Furthermore, in order to reduce the flow rate of the steel shot and improve the flow uniformity of the steel shot, a first baffle 37 is provided on the upper side of the inclined plate 351 in the guide plate 35 inside the hopper 31. A first material drop gap is formed between the first baffle 37 and the guide plate 35. The distance of the first material drop gap is not less than the diameter of the steel shot and less than twice the diameter of the steel shot. Preferably, the first material drop gap is also the same as the diameter of the steel shot.

[0052] Reference Figure 6 A second baffle 38 is vertically arranged above the horizontal plate 352 of the guide plate 35 in the hopper 31. A second material drop gap is formed between the second baffle 38 and the guide plate 35. The distance of the second material drop gap is not less than the diameter of the steel grit and less than twice the diameter of the steel grit. Preferably, the second material drop gap is also the same as the diameter of the steel grit. A vibration element 381 is also fixed on the side of the second baffle 38 away from the guide plate 35.

[0053] Reference Figure 6 Thus, by using the first baffle 37 and the second baffle 38 in conjunction with the guide plate 35, the amount of steel shot falling from the chip extraction zone 361 at the same time can be limited, the steel shot can flow down evenly, and the waste material can be discharged. Furthermore, due to the vibration element 381, the second baffle 38 can be vibrated to prevent the steel shot from clogging and ensure the smooth flow of the steel shot.

[0054] In summary, the principle of an embodiment of an environmentally friendly descaling machine for whole coil wire rods according to this application is as follows: First, the coil of wire rod to be descaled is extended and hung on the cantilever 12. Then, the coil is placed in the descaling chamber 1 by rotating the rotating door 11. Next, the throwing devices 14 are turned on. Driven by the forward and reverse rotation of the throwing motor 141, multiple throwing devices 14 throw steel shot onto the rotating wire rod on the cantilever 12 in both forward and reverse directions, thus achieving the descaling operation on the surface of the wire rod. When the thrower 14 throws steel shot onto the coil of wire rod, it will fall directly into the accumulation trough 2. Then, the screw conveyor 21 will send the steel shot in the accumulation trough 2 to the position of the elevator 4. The elevator 4 will then directly lift the steel shot upward and send it to the sand and debris separation chamber 3. After the lifted steel shot is sent to the sand and debris separation chamber 3, the steel shot will be separated from other impurities and debris. Then, the separated steel shot can enter the thrower 14 to continue the dephosphorization operation and realize the cycle.

[0055] Example 2: An environmentally friendly descaling machine for whole coils of wire rod differs from Example 1 in that: Both vertical sides of the revolving door 11 are equipped with curved rebound pads 113 corresponding to the cantilever 12, and the curved rebound pads 113 are all made of elastic rubber.

[0056] Compared with Example 1, the arc-shaped rebound pad 113 provided on the revolving door 11 in Example 2 can effectively rebound the steel shot that is ejected onto the revolving door 11, so that the steel shot can hit the coiled steel bar on the cantilever 12 again to remove phosphorus.

[0057] Example 3: Reference Figure 8 An environmentally friendly descaling machine for whole coils of wire rod differs from Embodiment 1 in that, to facilitate the installation and disassembly of the whole coils of wire rod on the cantilever 12, a different cantilever 12 structure is adopted in this embodiment, which is described in detail below: Reference Figure 8 The cantilever 12 includes two baffles 123 and a plurality of disc-shaped bodies 121 disposed between the two baffles 123. The disc-shaped bodies 121 located at both ends of the cantilever 12 are respectively fixed to the two baffles 123. The plurality of disc-shaped bodies 121 are arranged along the axial direction of the cantilever 12, and the sides of adjacent disc-shaped bodies 121 are slidably disposed relative to each other along a direction perpendicular to the axial direction of the cantilever 12. A push spring 124 is fixed between adjacent disc-shaped bodies 121. The push spring 124 can push the adjacent disc-shaped bodies 121 to maintain the axial misalignment state, thereby making the plurality of disc-shaped bodies 121 of the cantilever 12 arranged in a connected concave-convex structure.

[0058] Reference Figure 8A winch 16 is fixed to one end of the cantilever 12 away from the drive element. Each disc 121 and baffle 123 has a through hole 125 at its axial position. The wire rope of the winch 16 passes through each through hole 125 and is fixed to the disc 121 of the cantilever 12 near the drive element. As the winch 16 drives the wire rope to tighten, it can drive each baffle 123 to slide until the through hole 125 is in the same straight line.

[0059] Reference Figure 8 Thus, during the loading of the entire coil of wire rod, the winch 16, with its steel rope, rewinds the coil, causing multiple discs 121 to slide relative to each other onto the same axis. This allows the entire coil of wire rod to be easily loaded onto the cantilever 12, extending and spreading out on it. After loading, the winch 16 releases the wire, and the springs 124 between adjacent discs 121 activate, causing them to shift and maintain a continuous, convex-concave shape. With the cantilever 12 rotating via the drive element, the wire rod can rotate continuously on the cantilever 12. Because the cantilever 12 has a continuous concave-convex structure, it can create more space between the inner side of the wire rod and the cantilever 12. Furthermore, due to the push spring 124, the wire rod can bounce when rotating, thus achieving a thorough descaling effect. After the descaling operation is completed, the winch 16 pulls the steel cable to keep the multiple discs 121 coaxial, making it easy to remove the steel bar from the cantilever 12.

[0060] Reference Figure 8 Furthermore, one end of the winch 16 on the cantilever 12 is rotatably connected to a rotating cover 161 that can cover the winch 16. A slot 162 is provided on one side of the rotating cover 161, and a bolt 163 with its end that can be inserted into the slot 162 is also threadedly connected to it. A support arm 17 is horizontally rotatably connected to the revolving door 11. The support arm 17 can be rotatably inserted into the slot 162 of the rotating cover 161. One end of the rotating arm that can be inserted into the slot 162 also has a socket 171. After the support arm 17 is rotated into the slot 162, the bolt 163 is rotated until it is inserted into the socket 171, thereby fixing the support arm 17 to the rotating cover 161 and thus supporting the cantilever 12. When it is necessary to remove the wire rod, the bolt 163 is rotated in the opposite direction to disengage the bolt 163 from the socket 171, and then the support arm 17 is rotated to disengage from the slot 162 of the rotating cover 161, so that the wire rod can be easily removed.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
