Description

Technical Field

[0001] This utility model relates to the field of steel plate heat treatment technology, specifically a heat treatment equipment for stainless steel coils. Background Technology

[0002] Stainless steel coils possess high dimensional accuracy and excellent mechanical properties, making them suitable for a wide range of applications. Stainless steel coils are generally formed through cold rolling, a process known for its high production efficiency and ease of subsequent processing, thus being widely used in the forming of stainless steel coils.

[0003] In the production process, stainless steel coils need to be annealed using a continuous annealing furnace. During the heat treatment process using a continuous annealing furnace, cooling is required. Existing cooling methods mostly involve setting air jets on the side of the steel coils, and the cold air ejected from the air jets cools the steel coils. This results in the steel coils near the air jets cooling down faster, while those farther away from the air jets cool down slower, leading to uneven cooling and reducing the stability of the annealing heat treatment process. Therefore, a stainless steel coil heat treatment device is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A stainless steel coil heat treatment equipment of this utility model includes a continuous annealing furnace. A conveying box is connected to the outside of the continuous annealing furnace. A conveying assembly is provided inside the conveying box. Steel coils are slidably connected to both the inside of the continuous annealing furnace and the inside of the conveying box. The conveying assembly and the steel coils are used in conjunction. A water tank is fixedly connected to the outside of the conveying box. A water pump is fixedly connected to the inside of the water tank. A cooling pipe is connected to the outside of the water tank. The cooling pipe and the water pump are used in conjunction. A first motor is fixedly connected to the outside of the cooling pipe. A first positive and negative threaded screw is fixedly connected to the output end of the first motor. A sealing block is slidably connected to the inside of the cooling pipe. A connecting plate is fixedly connected to the outside of the sealing block. The connecting plate and the first positive and negative threaded screw are threadedly connected. A first heat-conducting plate is fixedly connected to the inner side of the sealing block. The first heat-conducting plate works in conjunction with the steel coil. This step involves setting up a cooling pipe, a first threaded screw, a sealing block, and a first heat-conducting plate. In use, a water pump injects coolant from the inside of the water tank into the inside of the cooling pipe. The coolant cools down the multiple first heat-conducting plates. Then, a first motor drives the first threaded screw to rotate, which in turn moves the sealing block and the first heat-conducting plate. When the sealing block slides, its elasticity allows it to stably seal the connection between the cooling pipe and the sealing block, making it difficult for the coolant to overflow. One end of the first heat-conducting plate is close to the wide surface of the steel coil, thus uniformly cooling the same position on the steel coil. This makes the annealing heat treatment of the device more stable and improves the stability of the device.

[0006] Preferably, a second threaded screw is threaded onto the inner side of the connecting plate. Synchronous gears are fixedly connected to the outer side of the second threaded screw and the output end of the first motor. A toothed plate meshes with the outer side of the synchronous gear, and the toothed plate is slidably connected to the cooling pipe. This step, by setting up the second threaded screw, synchronous gear, and toothed plate, ensures that when the first threaded screw rotates, one side of the synchronous gear drives the toothed plate to move, which in turn drives the other side of the synchronous gear to rotate. This allows the second threaded screw to rotate synchronously with the first threaded screw, enabling the second threaded screw to further drive the other end of the connecting plate to move. This makes the movement of the connecting plate, sealing block, and first heat-conducting plate more stable, improving the stability of the device.

[0007] Preferably, a second heat-conducting plate is fixedly connected to the inner side of the water tank, and a cooling fan is fixedly connected to the outer side of the conveying box. The cooling fan and the second heat-conducting plate work together. By setting up the second heat-conducting plate and the cooling fan, when the coolant inside the water tank circulates, the coolant can be further cooled by the second heat-conducting plate, and the second heat-conducting plate can be cooled by the cooling fan. This allows the heat brought by the coolant flowing back inside the water tank to be quickly removed, making the cooling of the coolant more stable and improving the stability of the device.

[0008] Preferably, a second motor is fixedly connected to the outside of the water tank, and a stirring rod is fixedly connected to the output end of the second motor. By setting up the second motor and the stirring rod, after the coolant flows back, the second motor can drive the stirring rod to rotate, and the stirring rod can mix the coolant, so that the heat carried by the flowing coolant can be quickly dispersed, further improving the stability of the device's heat dissipation.

[0009] Preferably, a limiting plate is fixedly connected to the outside of the cooling pipe, and the limiting plate and the toothed plate are slidably connected. This step, by setting the limiting plate and cooperating with the cooling pipe, further restricts the range of motion of the toothed plate, making the movement of the toothed plate more stable and improving the stability of the device.

[0010] Preferably, a brush is fixedly connected to the inside of the conveyor box. The brush works in conjunction with the steel coil. By setting up the brush, the surface of the steel coil is cleaned after it cools down, making it easier for subsequent processing and improving the convenience of using the device.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a cooling pipe, a first positive and negative threaded screw, a sealing block, and a first heat-conducting plate, allows for the use of a water pump to inject coolant from the inside of the water tank into the cooling pipe. The coolant then cools the multiple first heat-conducting plates. A first motor drives the first positive and negative threaded screw to rotate, which in turn moves the sealing block and the first heat-conducting plate. As the sealing block slides, its elasticity allows it to stably seal the connection between the cooling pipe and the pipe, preventing coolant from overflowing. Furthermore, one end of the first heat-conducting plate is close to the wide surface of the steel coil, resulting in uniform cooling of the same location on the steel coil. This makes the annealing heat treatment of the device more stable and improves the overall stability of the device.

[0013] 2. By setting a second positive and negative threaded screw, a synchronous gear, and a toothed plate, when the first positive and negative threaded screw rotates, the synchronous gear on one side will drive the toothed plate to move, and the toothed plate will drive the synchronous gear on the other side to rotate, so that the second positive and negative threaded screw rotates synchronously with the first positive and negative threaded screw. This allows the second positive and negative threaded screw to further drive the other end of the connecting plate to move, making the movement of the connecting plate, sealing block, and first heat-conducting plate more stable and improving the stability of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5As shown, a stainless steel coil heat treatment device includes a continuous annealing furnace 1. A conveyor box 2 is connected to the outside of the continuous annealing furnace 1. A conveying assembly 3 is installed inside the conveyor box 2. Steel coils 4 are slidably connected to both the inside of the continuous annealing furnace 1 and the inside of the conveyor box 2. The conveying assembly 3 and the steel coils 4 work together. A water tank 5 is fixedly connected to the outside of the conveyor box 2. A water pump 6 is fixedly connected to the inside of the water tank 5. A cooling pipe 7 is connected to the outside of the water tank 5. The cooling pipe 7 and the water pump 6 work together. A first motor 8 is fixedly connected to the outside of the cooling pipe 7. A first threaded screw 9 is fixedly connected to the output end of the first motor 8. A sealing block 10 is slidably connected to the inside of the cooling pipe 7. A connecting plate 11 is fixedly connected to the outside of the sealing block 10. The connecting plate 11 and the first threaded screw 9 are threadedly connected. A second threaded screw 9 is fixedly connected to the inside of the sealing block 10. A heat-conducting plate 12 is used in conjunction with the steel coil 4. This step involves setting up a cooling pipe 7, a first threaded screw 9, a sealing block 10, and the first heat-conducting plate 12. In use, a water pump 6 injects coolant from the inside of the water tank 5 into the inside of the cooling pipe 7, which cools the multiple first heat-conducting plates 12. Then, a first motor 8 drives the first threaded screw 9 to rotate, which in turn moves the sealing block 10 and the first heat-conducting plate 12. When the sealing block 10 slides, its elasticity allows it to stably seal the connection between the cooling pipe 7 and the steel coil 4, preventing coolant from overflowing. One end of the first heat-conducting plate 12 is close to the wide surface of the steel coil 4, thus uniformly cooling the same position of the steel coil 4. This makes the annealing heat treatment of the device more stable and improves the stability of the device.

[0024] Furthermore, such as Figure 1 and Figure 4 As shown, a second threaded screw 13 is threaded onto the inner side of the connecting plate 11. A synchronous gear 14 is fixedly connected to both the outer side of the second threaded screw 13 and the output end of the first motor 8. A toothed plate 141 meshes with the outer side of the synchronous gear 14. The toothed plate 141 is slidably connected to the cooling pipe 7. This step, by setting the second threaded screw 13, synchronous gear 14, and toothed plate 141, ensures that when the first threaded screw 9 rotates, one synchronous gear 14 drives the toothed plate 141 to move, and the toothed plate 141 drives the other synchronous gear 14 to rotate. This allows the second threaded screw 13 to rotate synchronously with the first threaded screw 9, enabling the second threaded screw 13 to further drive the other end of the connecting plate 11 to move. This makes the movement of the sealing block 10 and the first heat-conducting plate 12 by the connecting plate 11 more stable, improving the stability of the device.

[0025] Furthermore, such as Figure 2 and Figure 5As shown, a second heat-conducting plate 15 is fixedly connected to the inner side of the water tank 5, and a cooling fan 16 is fixedly connected to the outer side of the conveying box 2. The cooling fan 16 and the second heat-conducting plate 15 work together. By setting the second heat-conducting plate 15 and the cooling fan 16, when the coolant inside the water tank 5 circulates, the coolant can be further cooled by the second heat-conducting plate 15, and the second heat-conducting plate 15 can be cooled by the cooling fan 16. This allows the heat brought by the coolant flowing back inside the water tank 5 to be quickly removed, making the cooling of the coolant more stable and improving the stability of the device.

[0026] Furthermore, such as Figure 2 and Figure 5 As shown, a second motor 17 is fixedly connected to the outside of the water tank 5, and a stirring rod 18 is fixedly connected to the output end of the second motor 17. By setting the second motor 17 and the stirring rod 18, after the coolant flows back, the second motor 17 can drive the stirring rod 18 to rotate, and the stirring rod 18 can mix the coolant, so that the heat carried by the flowing coolant can be quickly dispersed, further improving the stability of the device's heat dissipation.

[0027] Furthermore, such as Figure 3 As shown, a limiting plate 19 is fixedly connected to the outside of the cooling pipe 7. The limiting plate 19 and the toothed plate 141 are slidably connected. This step, by setting the limiting plate 19, and by cooperating with the cooling pipe 7, further restricts the range of motion of the toothed plate 141, making the movement of the toothed plate 141 more stable and improving the stability of the device.

[0028] Furthermore, such as Figure 1 As shown, a brush 20 is fixedly connected to the inner side of the conveyor box 2. The brush 20 is used in conjunction with the steel coil 4. In this step, by setting the brush 20, after the steel coil 4 has cooled, the brush 20 contacts the steel coil 4 to clean its surface, so as to facilitate its subsequent processing and improve the convenience of using the device.

[0029] Working principle: During use, the coolant inside the water tank 5 is injected into the cooling pipe 7 by the water pump 6. The coolant cools down the multiple first heat-conducting fins 12. Then, the first motor 8 drives the first positive and negative thread screw 9 to rotate. The first positive and negative thread screw 9 drives the synchronous gear 14 to rotate. The synchronous gear 14 drives the toothed plate 141 to move. The toothed plate 141 drives the other synchronous gear 14 to rotate, so that the second positive and negative thread screw 13 rotates synchronously with the first positive and negative thread screw 9. This causes the connecting plate 11 to move. The connecting plate 11 drives the sealing block 10 and the first heat-conducting fins 12 to move, so that the first heat-conducting fins 12 are close to the steel coil 4. Then, the water pump 6 injects the coolant inside the water tank 5 into the cooling pipe 7. The coolant cools down the multiple first heat-conducting fins 12, and the first heat-conducting fins 12 cool down the steel coil 4.
