Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0018] like Figures 1 to 11 As shown, an embodiment of the present invention provides a cooling device for hot-dip galvanizing of alloy steel, including a storage frame 1 and two support rollers 4 rotatably disposed within the storage frame 1. A steel mesh belt 5 is sleeved on the outer side of the two support rollers 4. A motor 6 is fixed to the outer wall of the storage frame 1, and the drive end of the motor 6 is axially connected to one of the support rollers 4 through a shaft seal penetrating the storage frame 1. A support frame 7 is fixed on the storage frame 1, and a fan 8 is disposed through the upper end of the support frame 7. Multiple branch pipes 10 are disposed through the inside of the support frame 7, and nozzles 11 are disposed on the outer side of the branch pipes 10 perpendicular to the steel mesh belt 5. The device also includes: The suction section is located outside the support frame 7, with its upper end on the fan 8 and its lower end above the steel mesh belt 5. It includes an absorber located outside the support frame 7 and connected to the fan 8, as well as a collection member that penetrates the absorber to absorb dust and zinc dross on the steel using the wind power of the fan 8. The cleaning section is located outside the collection section and between the collection section and the steel mesh belt 5. It includes a drive support fixed to the outer wall of the absorber and the drive support movably passes through the storage frame 1, and a wiping member connected to the drive support. The wiping member is located between the absorber and the steel mesh belt 5 to separate impurities adhering to the steel. The cooling section is located inside the storage frame 1 and connected to the cleaning section. It includes a cooling member that is rotatably connected to the inner wall of the storage frame 1 and is located between two support rollers 4, and a accumulator that is connected to the cooling member. The accumulator passes around one of the support rollers 4 and is connected to the rubbing member so that the rubbing member drives the cooling member to reciprocate to cool the steel on the steel mesh belt 5.

[0019] Specifically, the storage frame 1 is fixed with support legs 2 at its bottom, and connecting pipes 3 are connected through both ends of the storage frame 1. A flange pipe 9 is fixed to the outer wall of the support frame 7, and the flange pipe 9 is connected to the branch pipe 10. The support legs 2 provide stable support for the storage frame 1. The storage frame 1 provides storage space and a flow channel for cooling water. The connecting pipes 3 provide a connection point with the pipeline transporting cooling water, allowing cooling water to enter the storage frame 1 through the connecting pipes 3 and exit to the outside through the connecting pipes 3. The storage frame 1 provides rotational support for the support rollers 4, and the support rollers 4 provide support for the steel mesh belt 5. The motor 6 can... Supported by frame 1, the drive end drives the support roller 4 to rotate, so that the support roller 4 can support the steel mesh belt 5 and use friction to drive the steel mesh belt 5 to rotate. The shaft seal can play a sealing role between the drive end of motor 6 and storage frame 1 to prevent water from leaking out of storage frame 1. The support frame 7 can provide support for flange pipe 9, fan 8 and branch pipe 10 under the support of storage frame 1. Fan 8 can accelerate the blowing of outside air towards steel mesh belt 5. Flange pipe 9 can provide a channel for cooling water to enter branch pipe 10. Branch pipe 10 can provide support for nozzle 11. Nozzle 11 can atomize and spray water in branch pipe 10.

[0020] In practical application, the operator can start the motor 6 to drive the steel mesh belt 5 to rotate and start the fan 8 to draw in outside air and blow it downwards onto the steel mesh belt 5. At the same time, the cooling water pipeline is connected to the flange pipe 9 using fixed components, allowing the cooling water to pass through the flange pipe 9 into the branch pipe 10 and fill the branch pipe 10. Under the action of water pressure, the water can pass through the nozzle 11 and be atomized and sprayed out. At the same time, the air blown downwards by the fan 8 will carry the water mist and move it onto the steel mesh belt 5. Then, the operator can arrange the hot-dip galvanized alloy steel that needs to be cooled onto the steel mesh belt 5. The steel mesh belt 5 will use its rotation to transport the alloy steel from left to right to the inside of the support frame 7 and through the support frame 7 to the next process. During the process of passing through the support frame 7, the alloy steel will come into contact with the air and water mist that are accelerating towards the steel mesh belt 5, so that the water mist and air work together to cool the alloy steel.

[0021] In a preferred embodiment of the present invention, the absorbent element includes: The five-pointed star tube 12 has a five-pointed star outline, an opening at the bottom, and is fixed to the upper end of the fan 8. The ventilation duct 13 is installed with one end penetrating one side of the five-star duct 12 and the other end extending above the steel mesh belt 5; The absorption component is connected to the lower end of the air duct 13.

[0022] Specifically, the five-star cylinder 12 can evenly cover part of the intake port of the fan 8, and can provide support for the air duct 13 under the support of the fan 8. The air duct 13 can provide a channel for air to enter the five-star cylinder 12. After the fan 8 is started, it will suck out the air in the five-star cylinder 12 and blow it into the support frame 7, so that a vacuum is formed inside the five-star cylinder 12.

[0023] The absorbing components include: Connecting cylinder 14 is fixed to the lower end of air duct 13; Corrugated cylinder 15 is connected to the lower end of connecting cylinder 14; The suction port 16 is conical, fixed to the lower end of the corrugated cylinder 15, and perpendicular to the steel mesh belt 5.

[0024] Specifically, the air duct 13 can provide support for the connecting tube 14, the connecting tube 14 can stably support the corrugated tube 15, the corrugated tube 15 can expand and contract under the action of external force, and can provide support for the suction port 16. After the inner side of the five-star tube 12 is vacuumed, the air in the air duct 13 will flow into the five-star tube 12, the air in the connecting tube 14 will enter the air duct 13, and the air in the suction port 16 will enter the connecting tube 14. Outside air will enter the suction port 16, thereby generating suction at the lower end of the suction port 16.

[0025] The collection includes: Frame 45, installed above the ventilation duct 13; The dust collection bag 40 is set inside the air duct 13 and extends into the five-star tube 12, and is located above the fan 8, with one end fixedly connected to the frame 45. Two inclined plates 41 are symmetrically fixed inside the frame 45 and inclined towards the dust collection bag 40. The sealing component is located above the dust collection bag 40 and is connected to the air duct 13.

[0026] Specifically, the air duct 13 provides a through channel and positioning support for the frame 45, and also provides support for the dust collection bag 40. The dust collection bag 40 provides a through channel for air and can intercept and store impurities. The frame 45 provides support for the inclined plate 41, and the inclined plate 41 provides a guiding function for impurities to pass through the frame 45 and enter the dust collection bag 40.

[0027] The tight-fitting components include: The cover plate 42 is fixed to the upper end of the frame 45 and is located above the air duct 13; The sealing ring 43 is fixed on the side of the cover plate 42 near the air duct 13, and is located on the outside of the frame 45 and fits against the outer wall of the air duct 13; A bolt is installed through the inside of the cover plate 42, and the bolt is threadedly connected to the air duct 13 to fix the cover plate 42 and compress the sealing ring 43.

[0028] Specifically, the frame 45 can provide support for the cover plate 42, the cover plate 42 can stably support the sealing ring 43, the sealing ring 43 can play a sealing role when it is tightly fitted with the air duct 13, the bolts can fasten the cover plate 42 to the air duct 13, so that the cover plate 42 and the air duct 13 cooperate to squeeze the sealing ring 43, and the outer wall of the connecting cylinder 14 is fixed with a support plate 25, and the support plate 25 is connected to the support frame 7 to stably support the connecting cylinder 14.

[0029] In practical application, when the fan 8 and motor 6 are started, the alloy steel material is conveyed and moved near the steel mesh belt 5. During the movement, the alloy steel material gradually moves and passes under the suction port 16. Air and impurities (dust, zinc dross) on the alloy steel material are accelerated and sucked into the inside of the suction port 16. The impurities entering the suction port 16 are carried by the airflow through the corrugated cylinder 15 into the connecting cylinder 14, and then through the connecting cylinder 14 into the air duct 13. Subsequently, guided by the air duct 13, the impurities pass through the air duct 13 and the frame 45 and connect with the inclined plate 41. The air is touched and guided by the inclined plate 41 into the dust collection bag 40, which provides a passage for air and intercepts impurities on its inner side. The air then passes through the dust collection bag 40 into the inner side of the five-star cylinder 12 and into the fan 8. The arrangement of the five-star cylinder 12 keeps the exposed area of ​​the fan 8 uniform, reducing the stress effect of uneven airflow position on the fan blades of the fan 8. This facilitates the use of the driving force of the fan 8 to adsorb and collect impurities on the alloy steel, preventing impurities from affecting the cooling of the alloy steel.

[0030] In a preferred embodiment of the present invention, the drive support member includes: The electric pole 19 has its fixed end connected to the outside of the air duct 13 via a fixing component; Fixed plate 20 is fixed to the outside of the telescopic end of electric pole 19; Motor 21 is connected to the bottom of fixed plate 20 by a fixing component and is located outside storage frame 1.

[0031] Specifically, the storage frame 1 has a through opening 17, and the outer wall of the air duct 13 is connected to an N plate 18 by a fixing component. The N plate 18 is fixedly connected to the electric rod 19. The N plate 18 can provide support for the electric rod 19 under the support of the air duct 13. The electric rod 19 can stably support the motor 21 through the fixing plate 20. The motor 21 can drive the rotating rod 23 to rotate by the drive end.

[0032] The rotary friction element includes: Support plate 22 is symmetrically fixed at the lower end of suction port 16; The rotating rod 23 rotates through the support plate 22 and moves through the storage frame 1; The brush roller 24 is fixed to the outside of the rotating rod 23 and is located between the suction port 16 and the steel mesh belt 5; The drive end of motor 21 is axially connected to the rotary rod 23.

[0033] Specifically, the suction port 16 can provide stable support for the support plate 22, the support plate 22 can provide rotational support for the rotating rod 23, the rotating rod 23 can provide support for the brush roller 24, and can use external force to drive the brush roller 24 to rotate together. When the brush roller 24 comes into contact with the alloy steel, it can use rotational power to peel off the impurities adhering to the alloy steel.

[0034] In practical application, before starting the motor 6, the operator can place the alloy steel on the steel mesh belt 5, positioning it between the brush roller 24 and the steel mesh belt 5. Then, the electric rod 19 is extended, causing it to push the motor 21 up and down via the fixed plate 20. The motor 21, through its drive end, drives the rotating rod 23 to adjust the height along the opening 17. Simultaneously, the rotating rod 23 moves the brush roller 24 and the support plate 22 together. The support plate 22, under external force, moves the suction port 16, allowing the suction port 16 to squeeze or stretch the corrugated cylinder 15, thus... 15. With the support of the connecting cylinder 14, the brush roller 24 is adjusted by external force following the extension and retraction of the lifting rod, so that it can be adjusted to the position of contact with the upper surface of the alloy steel. At the same time, the distance between the suction port 16 and the alloy steel is sufficient to absorb impurities. Then, the motor 6, fan 8 and motor 21 are started, so that the motor 21 can drive the brush roller 24 to rotate at a low speed through the rotating rod 23. The brush roller 24 uses rotational power to peel off the impurities on the alloy steel, which are then sucked into the suction port 16 for collection. This prevents the impurities adhering to the alloy steel from forming a protective layer during cooling, which would affect the cooling effect and improve the cooling efficiency and effect.

[0035] As a preferred embodiment of the present invention, the splash-proof component includes: Multiple connecting plates 26 are evenly fixed to the inner wall of the storage frame 1 by fixing components; Side plate 29 is fixed to one side of connecting plate 26 and is rotatably connected to the other end of spring 31; Multiple splash plates 28 are rotatably mounted on the connecting plate 26 and located between two support rollers 4; Grooves 33 are evenly distributed on the splash plate 28; Spring 31 is rotatably connected at one end to splash plate 28 and at the other end to side plate 29.

[0036] Specifically, a rotating rod 27 is fixed on the connecting plate 26, and a splash plate 28 is rotatably disposed on the outside of the rotating rod 27. A spring seat 30 is rotatably disposed on the side plate 29, and another spring seat 30 is rotatably connected to the side of the splash plate 28 near the side plate 29. A spring 31 is connected between the two spring seats 30 to achieve a rotatable connection with the splash plate 28 and the side plate 29. The connecting plate 26 provides stable support for the rotating rod 27, the rotating rod 27 provides rotational support for the splash plate 28, and the splash plate 28 provides support for the groove 33. The groove 33 provides space for water to be temporarily stored, and the connecting plate 26 can stably support the side plate 29. The side plate 29 and the splash plate 28 can provide rotational support for the spring seat 30. The spring seat 30 can provide support for the spring 31. The spring 31 is elastic. In its natural state, it can use its elasticity to keep the splash plate 28 in an inclined state under the support of the side plate 29 and the spring seat 30. It can also be pulled and deformed by external force, so that the splash plate 28 can rotate counterclockwise around the rotating rod 27 into the cooling water in the storage frame 1.

[0037] The accumulator includes: The end of the splash plate 28 that is away from the connecting plate 26 extends outward toward the steel mesh belt 5; The hanging ring 32 is fixed on the splash plate 28 and is located outside the steel mesh belt 5; Multiple retaining rings 34 are evenly fixed to the inner bottom wall of the storage frame 1; A pull cord 35 is set through the retaining ring 34, with one end extending to the bottom of the splash plate 28 furthest from the suction port 16. The rotating part is set on the rotating rod 23 and one of the support rollers 4.

[0038] Specifically, the splash plate 28 provides support for the hanging ring 32, the hanging ring 32 provides support for the connecting rope 36, and the retaining ring 34 provides a passage and a blocking function for the pull rope 35 and the connecting rope 36.

[0039] The rotary drawing parts include: The connecting rope 36 has multiple parts, one end of which is connected to the hanging ring 32, and the other end is connected to the pull rope 35; Pulley 44 is rotatably mounted on the outside of one of the support rollers 4; The other end of the rope 35 is U-shaped and passes around the pulley 44 to connect with the winding wheel 37; The swivel 37 is sleeved on the outside of the rotating rod 23; The first arc block 38 is fixed on the inner side of the circumferential wheel 37; The second arc block 39 is fixed on the outside of the rotating rod 23 and is adjacent to the first arc block 38.

[0040] Specifically, the support roller 4 provides rotational support for the pulley 44, allowing the pulley 44 to remain stationary under external force and rotate around the support roller 4 under external force, thus making the pull rope 35 move more smoothly. The first arc block 38 provides a blocking effect for the second arc block 39, allowing the rotating rod 23 to push the first arc block 38 and the wheel 37 to rotate together through the second arc block 39. The first arc block 38 and the second arc block 39 are elastic and can deform under external force and after the spring 31 has reached its limit of compression, allowing the second arc block 39 to bypass the first arc block 38 and release the push on the first arc block 38.

[0041] In practical application, after the motor 21 starts, it drives the second arc block 39 and the brush roller 24 to rotate clockwise together via the rotating rod 23. This allows the second arc block 39 to contact the first arc block 38 during rotation, and the rotational power pushes the first arc block 38 to rotate together. The first arc block 38 then drives the winding wheel 37 to rotate together, allowing the winding wheel 37 to continuously wind and wrap the pull rope 35 during rotation. As the pull rope 35 moves under external force, friction pushes the pulley 44 to rotate smoothly under the support of the support roller 4. As the clock hands rotate, the pull rope 35 moves through the retaining ring 34 during the winding process, pulling the connecting rope 36 to move together and pass through the retaining ring 34. This allows the connecting rope 36 to move closer to the retaining ring 34 under external force, enabling it to pull the splash plate 28 through the hanging ring 32. The splash plate 28 then rotates counterclockwise around the rotating rod 27, and during this counterclockwise rotation, it works in conjunction with the spring seat 30 to compress the spring 31. Simultaneously, the spring seat 30 will press against the side plate 29 and the splash plate 28 during the rotation of the splash plate 28. Supported by the rotation, the spring 31 can be compressed to its limit. At this time, the splash plate 28 will move into the cooling water in the storage frame 1 (submerged). Then, as the rotating rod 23 continues to rotate, the rotating rod 23 uses its rotational power to drive the second arc block 39 to squeeze the first arc block 38, thereby causing the second arc block 39 and the first arc block 38 to contract and deform, allowing the second arc block 39 to bypass the first arc block 38, thus releasing the drive on the rotating wheel 37. At the same time, the tension received by the spring 31 will disappear, and the spring 31 will then utilize... Supported by the spring seat 30, the rebound force pushes the splash plate 28 to rotate clockwise around the rotating rod 27 to reset. At the same time, the splash plate 28 will pull the connecting rope 36 and the pull rope 35 together through the hanging ring 32, so that the wound pull rope 35 can pull the wheel 37 to rotate in the opposite direction to release the wound pull rope 35. Then, the splash plate 28 can use the rebound force in conjunction with the groove 33 to splash cooling water onto the bottom of the alloy steel conveyed on the steel mesh belt 5, thereby simultaneously cooling the bottom of the alloy steel and improving the cooling efficiency of the alloy steel.

[0042] Then, as the lever 23 continues to rotate, the above operation is repeated.

[0043] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
