Description

Technical Field

[0001] This utility model relates to the field of metallurgical machining technology, and in particular to an environmentally friendly cooling device for processing guide plates of metallurgical rolling mills. Background Technology

[0002] In the metallurgical industry, rolling mills are extremely critical equipment, and guide plates, as important components of rolling mills, play an indispensable role in guiding the rolled workpiece, preventing it from deviating, and ensuring rolling accuracy during the rolling process. During the processing of guide plates, especially after hot working processes such as forging, welding, and heat treatment, they are in a high-temperature state. At this time, effective cooling becomes a key link to ensure the quality and performance of guide plates.

[0003] Traditional cooling methods for guide plates have many drawbacks. For example, some simple water cooling methods simply spray water directly onto the surface of the guide plate through water pipes. Although this method can remove heat to some extent, it requires a large amount of cooling water during long-term cooling operations, which does not conform to the current concept of environmental protection and water conservation. Moreover, because the distribution of water flow is difficult to control precisely, it often leads to excessively rapid cooling in some parts of the guide plate while other parts are not cooled enough. This results in large thermal stress inside the guide plate, and the accumulation of thermal stress can easily cause quality defects such as deformation and cracking of the guide plate, which seriously affects the service life and rolling accuracy of the guide plate.

[0004] Therefore, there is an urgent need to provide an environmentally friendly cooling device for the processing of guide plates in metallurgical rolling mills to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an environmentally friendly cooling device for processing guide plates of metallurgical rolling mills.

[0006] To solve the above-mentioned technical problems, the present invention provides an environmentally friendly cooling device for processing guide plates of metallurgical rolling mills, including a cooling box, wherein the front end of the cooling box is provided with a placement hole and an operating table.

[0007] The cooling box is equipped with a conveying mechanism, which in turn is equipped with multiple clamping mechanisms. Each clamping mechanism has a high-temperature plate installed inside. Two pre-cooling air groups are fixedly connected to the bottom of the cooling box. The cooling box is also equipped with an atomizing cooling mechanism. Multiple drying air groups are fixedly connected to the top of the cooling box. A drain outlet is provided at the bottom of the cooling box. Multiple racks are fixedly connected to the inside of the cooling box.

[0008] The present invention is further configured such that: the conveying mechanism includes two motor housings installed inside the cooling box, each motor housing has a drive motor installed inside, the output ends of each drive motor are fixedly connected to a drive gear plate, a driven gear plate corresponding to the drive gear plate is rotatably connected inside the cooling box, a synchronizing rod is installed between each of the two drive gear plates and the two driven gear plates, and a chain is installed between each of the drive gear plate and the driven gear plate.

[0009] With the above technical solution, the drive motor installed in the motor housing inside the cooling box starts to work. The drive gear plate fixedly connected to its output end will rotate with the rotation of the motor shaft. The synchronizing rod installed between the two drive gear plates and the two driven gear plates plays the role of synchronous rotation, ensuring the stability and synchronicity of the entire transmission system. When the drive gear plate rotates, the chain will circulate with the rotation of the gear to carry out the transmission motion.

[0010] The present invention is further configured such that the operating table is electrically connected to the drive motor, the pre-cooling air group and the drying air group via wires.

[0011] Through the above technical solution, the control panel is connected to the drive motor, pre-cooling air group and drying air group by wires. The operator can centrally control these different equipment components from a single position on the control panel. By simply operating the corresponding buttons, knobs or touch screens on the control panel, the operator can simultaneously or separately control the speed of the drive motor to adjust the conveying speed, the air volume and speed of the pre-cooling air group and the operating status of the drying air group, which greatly improves the convenience and efficiency of operation.

[0012] The present invention is further configured such that: the clamping mechanism includes a fixing block installed on the inner side of two chains, a rotating gear is rotatably connected inside the two fixing blocks, a rotating plate is fixedly connected between the two rotating gears, a placement groove corresponding to the high-temperature plate is opened inside the rotating plate, a fixing rod is fixedly connected to both sides of the front end of the rotating plate, a rotating block is rotatably connected to the outer wall of the two fixing rods, an operating hole is opened at the front end of the two rotating blocks, and a limiting rod corresponding to the rotating block is fixedly connected to the front end of the rotating plate.

[0013] With the above technical solution, when cooling of the high-temperature plate is required, the high-temperature plate is placed in the placement groove inside the rotating plate using a specialized placement tool. The size of the placement groove is adapted to the high-temperature plate, providing initial positioning. When clamping the high-temperature plate is needed, external force is applied to the rotating blocks through the operating holes. The two rotating blocks clamp the high-temperature plate simultaneously from both sides, firmly fixing it in the placement groove and preventing displacement during subsequent conveying and cooling processes. The limiting rod at the front end of the rotating plate restricts the rotation range of the rotating blocks. When the rotating blocks clamp the high-temperature plate, once they rotate to a certain angle, they will contact the limiting rod. The limiting rod acts as a stop, preventing the rotating blocks from rotating excessively and no longer limiting the clamping of the high-temperature plate, thus preventing the plate from falling off during subsequent operations.

[0014] The present invention is further configured such that the rotating gear meshes with the corresponding rack.

[0015] With the above technical solution, when the rotating gear and the rack mesh with each other, since the tooth pitch of the rack is fixed, the rotating gear will rotate a certain angle every time it turns one tooth, thus realizing the rotation of the clamping mechanism.

[0016] The present invention is further configured such that: the atomizing cooling mechanism includes a water storage tank installed inside the cooling box; a water supply pipe is fixedly connected inside the water storage tank; a booster pump corresponding to the water supply pipe is fixedly connected to the top of the water storage tank; a water distribution pipe is fixedly connected to the outer wall of the water supply pipe; and mounting plates are fixedly connected to the other ends of both the water supply pipe and the water distribution pipe; and multiple atomizing nozzles are fixedly connected to the inner sides of both mounting plates.

[0017] Through the above technical solution, the water tank serves as the storage container for the coolant. The booster pump pressurizes the coolant in the water supply pipe. When the booster pump starts, it draws coolant from the water tank and increases its pressure so that the coolant can smoothly pass through the subsequent piping system and form an atomization effect at the nozzle. When the pressurized coolant reaches the atomizing nozzle through the water supply pipe and the distribution pipe, the atomizing nozzle breaks the coolant into tiny droplets. These tiny droplets have a large surface area, enabling them to fully exchange heat with the high-temperature plate. When the droplets come into contact with the surface of the high-temperature plate, they quickly absorb heat and vaporize, thereby carrying away the heat from the high-temperature plate and achieving the purpose of cooling. Because the droplets are very small, they can more evenly cover the surface of the high-temperature plate, avoiding the problems of local over-cooling or under-cooling, and improving the cooling effect.

[0018] The present invention is further configured such that the plurality of atomizing nozzles are fixedly connected at 45° to the inside of the mounting plate.

[0019] With the above technical solution, when the atomizing nozzle is fixed at a 45° angle to the inside of the mounting plate, the sprayed atomized coolant can cover the high-temperature guide plate at an inclined angle. The inclined spraying method can make the droplets cover a wider range on the surface of the guide plate, improve the cooling efficiency, and enable the guide plate to cool down faster.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model, through the design of a clamping mechanism, initially fixes the position of the high-temperature plate after it is placed in the placement slot, reducing the possibility of significant displacement of the high-temperature plate during subsequent operations. The rotating block rotatably connected to the fixing rod can be operated through the operating hole to rotate the rotating block towards the high-temperature plate, so that the two rotating blocks limit the high-temperature plate from both sides, preventing it from shifting due to factors such as the impact of coolant and the vibration of the conveying mechanism during the cooling process. It does not require complicated operating steps or special equipment, reducing the difficulty of the operator's work.

[0022] 2. This utility model, through the design of an atomizing cooling mechanism, uses multiple atomizing nozzles at 45° angles to enable coolant droplets to diffuse in both horizontal and vertical directions. This allows the droplets to better cover all surfaces of the high-temperature guide plate, including the front, side, and top edges, ensuring that the entire guide plate is in contact with the coolant droplets and avoiding cooling blind spots, thereby achieving a more uniform cooling effect.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0030] Please see Figure 1 and Figure 2 An environmentally friendly cooling device for processing guide plates in metallurgical rolling mills includes a cooling box 1, with a placement hole 2 and an operating table 3 installed at the front end of the cooling box 1.

[0031] like Figure 3As shown, a conveying mechanism 4 is installed inside the cooling box 1. The conveying mechanism 4 includes two motor housings 401 installed inside the cooling box 1. Each of the two motor housings 401 houses a drive motor 402. The operating console 3 is electrically connected to the drive motors 402, the pre-cooling air group 7, and the drying air group 9 via wires. By connecting the operating console 3 to the drive motors 402, the pre-cooling air group 7, and the drying air group 9 via wires, the operator can centrally control these different equipment components from a single location on the operating console 3. By operating the corresponding buttons, knobs, or touch screens on the operating console 3, the operator can simultaneously or separately control the speed of the drive motors 402 to adjust the conveying speed, the air volume and speed of the pre-cooling air group 7, and the operating status of the drying air group 9, greatly improving the convenience and efficiency of operation. The output ends of the two drive motors 402 are fixedly connected to the drive gear plates 403. The interior of the cooling box 1 is rotatably connected to the driven gear plates 404 corresponding to the drive gear plates 403. Synchronizing rods 405 are installed between the driving gear plate 403 and the two driven gear plates 404. A chain 406 is installed between each driving gear plate 403 and the driven gear plate 404. When the drive motor 402 installed in the motor housing 401 inside the cooling box 1 starts to work, the driving gear plate 403 fixedly connected to its output end will rotate with the rotation of the motor shaft. The synchronizing rods 405 installed between the two driving gear plates 403 and the two driven gear plates 404 play a role in synchronizing rotation, ensuring the stability and synchronization of the entire transmission system. When the driving gear plate 403 rotates, the chain 406 will circulate with the rotation of the gears to perform transmission motion.

[0032] like Figure 4 As shown, the conveying mechanism 4 has multiple clamping mechanisms 5 inside. Each clamping mechanism 5 includes a fixing block 501 installed inside two chains 406. A rotating gear 502 is rotatably connected inside each fixing block 501. The rotating gear 502 meshes with a corresponding rack 11. When the rotating gear 502... When meshing with the rack 11, since the tooth pitch of the rack 11 is fixed, the rotating gear 502 will rotate a certain angle every time it rotates one tooth, realizing the rotation of the clamping mechanism 5. A rotating plate 503 is fixedly connected between the two rotating gears 502. The interior of the rotating plate 503 is provided with a placement groove 504 corresponding to the high temperature plate 6. Fixed rods 505 are fixedly connected to both sides of the front end of the rotating plate 503. Rotating blocks 506 are rotatably connected to the outer walls of the two fixed rods 505. Operating holes 507 are provided at the front ends of the two rotating blocks 506. A limiting rod 508 corresponding to the rotating block 506 is fixedly connected to the front end of the rotating plate 503. High temperature plates 6 are installed inside the multiple clamping mechanisms 5. Two pre-cooling air groups 7 are fixedly connected to the bottom of the interior of the cooling box 1.

[0033] like Figure 4 As shown, when the high-temperature plate 6 needs to be cooled, it is placed in the placement groove 504 inside the rotating plate 503 using a special placement tool. The size of the placement groove 504 is adapted to the high-temperature plate 6, which can play a preliminary positioning role for the high-temperature plate 6. When it is necessary to clamp the high-temperature plate 6, an external force is applied to the rotating block 506 through the operating hole 507. The two rotating blocks 506 clamp the high-temperature plate 6 from both sides at the same time, so that the high-temperature plate 6 is firmly fixed in the placement groove 504, preventing the high-temperature plate 6 from shifting during subsequent conveying and cooling. The limiting rod 508 at the front end of the rotating plate 503 is used to limit the rotation range of the rotating block 506. When the rotating block 506 is clamping the high-temperature plate 6, once it rotates to a certain angle, it will contact the limiting rod 508. The limiting rod 508 plays a blocking role, preventing the rotating block 506 from rotating excessively and no longer limiting the high-temperature plate 6, so that the high-temperature plate 6 will fall off in subsequent work.

[0034] like Figure 5 As shown, the cooling box 1 is equipped with an atomizing cooling mechanism 8. The atomizing cooling mechanism 8 includes a water storage tank 801 installed inside the cooling box 1. A water supply pipe 802 is fixedly connected inside the water storage tank 801. A booster pump 803 corresponding to the water supply pipe 802 is fixedly connected to the top of the water storage tank 801. A water distribution pipe 804 is fixedly connected to the outer wall of the water supply pipe 802. The other ends of the water supply pipe 802 and the water distribution pipe 804 are both fixedly connected to mounting plates 805. Multiple atomizing nozzles 806 are fixedly connected to the inner sides of the two mounting plates 805. The multiple atomizing nozzles 806 are fixedly connected to the inner sides of the mounting plates 805 at a 45° angle. When the atomizing nozzles 806 are fixed at a 45° angle to the inner sides of the mounting plates 805, the sprayed atomized coolant can cover the high-temperature guide plate at an inclined angle. The inclined spraying method can make the atomized droplets cover a wider range on the surface of the guide plate, improve the cooling efficiency, and make the guide plate more effective. The system allows for faster cooling. The water tank 801 is a storage container for the coolant. The booster pump 803 pressurizes the coolant in the water supply pipe 802. When the booster pump 803 starts, it draws coolant from the water tank 801 and increases its pressure so that the coolant can smoothly pass through the subsequent piping system and form an atomization effect at the nozzle. When the pressurized coolant reaches the atomizing nozzle 806 through the water supply pipe 802 and the distribution pipe 804, the atomizing nozzle 806 breaks the coolant into tiny droplets. These tiny droplets have a large surface area and can fully exchange heat with the high-temperature plate 6. When the droplets come into contact with the surface of the high-temperature plate 6, they quickly absorb heat and vaporize, thereby carrying away the heat from the high-temperature plate 6 and achieving the purpose of cooling. Because the droplets are very small, they can more evenly cover the surface of the high-temperature plate 6, avoiding the problem of local over-cooling or under-cooling and improving the cooling effect.

[0035] like Figure 2 and Figure 5 As shown, multiple drying air units 9 are fixedly connected to the top of the interior of the cooling box 1, and a drain outlet 10 is provided at the bottom of the cooling box 1. Multiple racks 11 are fixedly connected to the interior of the cooling box 1.

[0036] When using this invention, if cooling of the high-temperature plate 6 is required, the operator needs to use a special holding tool to clamp the high-temperature plate 6 and place it in the placement groove 504 inside the rotating plate 503. External force is applied to the rotating blocks 506 through the operating hole 507, and the two rotating blocks 506 simultaneously clamp the high-temperature plate 6 from both sides, firmly fixing it in the placement groove 504. The rotating plate 503, having completed the clamping operation, will move along the chain 406, advancing towards different positions in the cooling box 1. When it reaches the position with the pre-cooling air group 7, the two pre-cooling air groups 7 will start operating to perform preliminary cooling treatment on the high-temperature plate 6. As the chain 406 continues to move... The operation causes the rotating plate 503 carrying the high-temperature plate 6 to reach the interior of the atomizing cooling mechanism 8. At this time, the rotating gear 502 begins to contact the rack 11. Since the tooth pitch of the rack 11 is fixed, the rotation of the rotating gear 502 will drive the rotating plate 503 carrying the high-temperature plate 6 to rotate, thus enabling the rotating plate 503 carrying the high-temperature plate 6 to rotate on its own axis. At this time, the atomizing cooling mechanism 8 will start to operate and begin to spray tiny droplets onto the rotating plate 503 carrying the high-temperature plate 6. Because the droplets are very small, they can more evenly cover the surface of the high-temperature plate 6 for cooling. Finally, the high-temperature plate 6, after cooling, will be dried by the drying air group 9 and then removed by the staff at the placement hole 2.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
