Description

Technical Field

[0001] This invention relates to the field of cooling technology in special steel production, specifically to a water-cooling device for rapid cooling of special steel production lines. Background Technology

[0002] Cooling is a crucial step in the production of special steels, as it directly affects not only the mechanical properties of the steel but also its microstructure and final quality. Special steels typically have unique chemical compositions and performance requirements, necessitating more precise control of their cooling process to ensure superior mechanical properties, corrosion resistance, and high-temperature resistance.

[0003] A rapid cooling device for a medium-sized special steel production line (Announcement No.: CN207507988U) includes a high-pressure water hose, a main water pipe, a support plate, a connecting hose, a guide groove, and a "duckbill" shaped nozzle. The high-pressure water hose is connected to the inlet of one end of the main water pipe, and the outlet of the other end of the main water pipe is connected to the "duckbill" shaped nozzle via the connecting hose. The "duckbill" shaped nozzle sprays water through the guide groove to cool the high-temperature special steel. The support plate is located below the main water pipe and above the guide groove to support the main water pipe. The outlet of the other end of the main water pipe is fixed to the connecting hose with a clamp. The "duckbill" shaped nozzle consists of four nozzles, three of which are installed on the guide groove, and the fourth nozzle is installed on the side of the guide groove.

[0004] The aforementioned patent achieves a small footprint and convenient construction through the cooperation of components such as the main water pipe and support plate. The rapid cooling device further reduces production costs, increases the profit margin of manufacturing enterprises, and reduces energy consumption. However, it cannot achieve a better uniform distribution and intense disturbance of cooling water in the circumferential and axial directions of the steel. On the one hand, it greatly enhances heat exchange efficiency and rapidly breaks down the steam insulation film, solving the problem of single cooling intensity in traditional water-cooling processes. Therefore, we propose a water-cooling device for rapid cooling of special steel production lines. Summary of the Invention

[0005] This invention proposes a water-cooling device for rapid cooling of special steel production lines.

[0006] The technical solution of the present invention is as follows: A water-cooling device for rapid cooling of a special steel production line includes a transport seat, a transport belt is provided on the inner side of the transport seat, a cooling chamber is provided on the top of the transport seat, and a rapid water-cooling device is provided on the top of the cooling chamber. The rapid water cooling device includes a fixed plate, the bottom of which is fixedly connected to the top of the cooling chamber. A motor is fixedly connected to the side of the fixed plate, and a reciprocating lead screw is fixedly connected to the output shaft of the motor. A threaded sleeve is threadedly connected to the circumferential surface of the reciprocating lead screw. A cooling water pump box is fixedly connected to the top of the cooling chamber. A force-bearing rod A is slidably connected to one end of the cooling water pump box, and a main water pipe is fixedly connected to the other end of the cooling water pump box. A circular water distribution plate is fixedly connected to the bottom end of the main water pipe. A water spray pipe is fixedly connected to the circumferential surface of the circular water distribution plate, and a water spray branch pipe is fixedly connected to the circumferential surface of the water spray pipe. A push rod A is fixedly connected to the circumferential surface of the threaded sleeve, and a limit rod A is fixedly connected to the side of the fixed plate. By rationally distributing the cooling water flow, the steel is cooled rapidly, avoiding quality problems caused by uneven cooling. The cooling water is sprayed out through the motor drive and the reciprocating motion of the lead screw, reducing manual intervention. This rapid water cooling device is mainly designed to improve the cooling efficiency of the steel, ensure uniform cooling, and improve production efficiency through an automated control system.

[0007] A return spring A is fixedly connected to the circumferential surface of the force-bearing rod A, and one end of the return spring A is fixedly connected to one end of the cooling water pump box. This ensures that the entire cooling system operates efficiently and stably, accurately controls the flow rate and spraying effect of the cooling water, and ultimately achieves uniform cooling of the steel.

[0008] One end of the force-bearing rod A is located on the displacement trajectory of the push rod A, and the circumferential surface of the threaded sleeve is slidably connected to the circumferential surface of the limiting rod A. This design is to ensure precise matching and synchronous movement between the push rod A and the force-bearing rod A, while limiting and adjusting the range of movement through the sliding connection between the threaded sleeve and the limiting rod A.

[0009] A water inlet pipe is installed on the top of the cooling water pump box, and a rubber stopper is inserted into the inner side of the water inlet pipe. The design of the rubber stopper inserted into the inner side of the water inlet pipe is mainly used to seal the water inlet and prevent water leakage.

[0010] A coolant circulation device is installed on the inner bottom of the transport seat. The coolant circulation device includes a circulating water pump box, the bottom of which is fixedly connected to the inner bottom of the transport seat. One end of the circulating water pump box is fixedly connected to a water inlet pipe, and the other end is fixedly connected to a concave water collection tank. A force-bearing rod B is slidably connected to the other end of the circulating water pump box. A belt A is installed on the circumferential surface of the reciprocating lead screw, and a belt shaft A is driven to the circumferential surface of the reciprocating lead screw via belt A. A connecting rod A is fixedly connected to the side of the cooling chamber, and one end of the connecting rod A is rotatably connected to the circumferential surface of the belt shaft A. Next, a belt B is mounted on the circumferential surface of the belt shaft A, and the belt shaft B is connected to the circumferential surface of the belt shaft A via the belt B drive. A reciprocating threaded groove is formed on the circumferential surface of one end of the belt shaft B, and a movable sleeve is threadedly connected to the reciprocating threaded groove of the belt shaft B. A push rod B is fixedly connected to the circumferential surface of the movable sleeve. A connecting rod B is fixedly connected to the side of the transport seat. One end of the connecting rod B is rotatably connected to the circumferential surface of the belt shaft B, and a limit rod B is rotatably connected to the other end of the connecting rod B. A water supply pipe is fixedly connected to the side of the circulating water pump box, and the other end of the water supply pipe is fixedly connected to the side of the cooling water pump box. This design allows the coolant sprayed from the rapid water cooling device to be collected and transported back to the cooling water pump box for reuse, achieving a reuse and environmentally friendly effect.

[0011] The circumferential surface of the limiting rod B is slidably connected to the circumferential surface of the movable sleeve, and one end of the force-bearing rod B is located on the displacement trajectory of the push rod B. The design and cooperation of the limiting rod B and the force-bearing rod B can effectively control the force and limit the displacement while ensuring the stable operation of the system, thus ensuring the efficient and safe operation of the entire mechanical system.

[0012] A one-way valve A is fixedly connected to the circumference of the water supply pipe, and a one-way valve B is fixedly connected to the circumference of the water receiving pipe. A return spring B is fixedly connected to the circumference of the force-bearing rod B, and one end of the return spring B is fixedly connected to the other end of the circulating water pump box. The cooperation of these components ensures the unidirectional flow of water, prevents backflow, and enables the system to self-regulate and recover through the return spring B, ensuring the stability and normal operation of the water pump and pipeline system under different working conditions.

[0013] A cooling optimization device is installed on the top of the cooling chamber. This device includes a slot on the top of the cooling chamber. A fixed housing is fixedly connected to the inner side of the cooling chamber, and a motor is fixedly connected to the inner side of the fixed housing. A fan blade is fixedly connected to the output shaft of the motor. Air vents A and B are located at the bottom of the fixed housing. Through the cooperation of the slot, motor, and fan blades, a strong airflow is provided, increasing heat dissipation. The overall layout of the cooling optimization device improves the system's cooling efficiency, ensuring the equipment remains within a suitable temperature range during operation, thereby improving the equipment's stability and lifespan.

[0014] The fan blades direct the airflow vertically downwards, and there is a gap between the circumferential surface of the fan blades and the side of the fixed shell. This directly propels the air downwards, enhancing the heat dissipation effect.

[0015] The air vents A and B face opposite directions, and multiple air vents A and B are arranged in a linear array along the bottom of the fixed shell. This ensures uniform airflow within the cooling chamber, avoids dead zones and stagnant air areas, improves cooling efficiency, and makes the cooling system not only highly efficient but also more energy-saving.

[0016] The working principle and beneficial effects of this invention are as follows: 1. This invention, through the coordinated operation of components such as a motor and a cooling water pump box, ensures uniform distribution and intense disturbance of cooling water in the circumferential and axial directions of the steel. On the one hand, it greatly enhances heat exchange efficiency and quickly breaks down the steam insulation film; on the other hand, it allows the steel to bear uniform cooling force and thermal stress throughout its body, fundamentally solving the deformation defects such as bending and warping of steel caused by uneven cooling, ensuring excellent straightness and geometric accuracy of the product, and dynamically adjusting the water pressure and flow rate of each cooling section, effectively solving the problem of single cooling intensity in traditional water-cooling processes.

[0017] 2. This invention achieves efficient utilization of water resources and thermal energy by integrating a highly efficient water circulation and thermal management system. It recycles, purifies, and cools the cooling water, continuously providing a stable, clean, and appropriately temperature-controlled cooling medium for the water-cooling device. This significantly reduces the consumption of fresh water and wastewater discharge during production, solves the problems of high resource waste and high operating costs associated with traditional direct-discharge cooling systems, ensures the long-term stability and reliability of the cooling process, and achieves a green and environmentally friendly effect.

[0018] 3. This invention achieves powerful airflow and enhances heat dissipation through the cooperation of components such as fan blades and air vents A. The layout of the entire cooling optimization device improves the cooling efficiency of the system, ensuring that the equipment remains within a suitable temperature range during operation, thereby improving the stability and lifespan of the equipment.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1 like Figures 1 to 7 As shown, this embodiment proposes a water-cooling device for rapid cooling of a special steel production line, including a transport seat 1, a transport belt 2 provided on the inner side of the transport seat 1, a cooling chamber 3 provided on the top of the transport seat 1, and a rapid water-cooling device 4 provided on the top of the cooling chamber 3. The rapid water cooling device 4 includes a fixed plate 41, the bottom of which is fixedly connected to the top of the cooling chamber 3. A motor 42 is fixedly connected to the side of the fixed plate 41. A reciprocating screw 43 is fixedly connected to the output shaft of the motor 42. A threaded sleeve 44 is threadedly connected to the circumferential surface of the reciprocating screw 43. A cooling water pump box 45 is fixedly connected to the top of the cooling chamber 3. A force rod A46 is slidably connected to one end of the cooling water pump box 45. A main water pipe 47 is fixedly connected to the other end of the cooling water pump box 45. A circular water distribution plate 48 is fixedly connected to the bottom end of the main water pipe 47. A water spray pipe 49 is fixedly connected to the circumferential surface of the circular water distribution plate 48. A water spray branch pipe 410 is fixedly connected to the circumferential surface of the water spray pipe 49. A push rod A411 is fixedly connected to the circumferential surface of the threaded sleeve 44. A limit rod A412 is fixedly connected to the side of the fixed plate 41. By rationally distributing the cooling water flow, the steel is cooled down quickly, avoiding quality problems caused by uneven cooling. The cooling water is sprayed out by the motor 42 and the reciprocating screw 43, reducing manual intervention. This rapid water cooling device 4 is mainly used to improve the cooling efficiency of the steel, ensure uniform cooling, and improve production efficiency through the automated control system.

[0025] A return spring A413 is fixedly connected to the circumferential surface of the force-bearing rod A46, and one end of the return spring A413 is fixedly connected to one end of the cooling water pump box 45. This ensures that the entire cooling system operates efficiently and stably, accurately controls the flow rate and spraying effect of the cooling water, and ultimately achieves uniform cooling of the steel.

[0026] One end of the force-bearing rod A46 is located on the displacement trajectory of the push rod A411, and the circumferential surface of the threaded sleeve 44 is slidably connected to the circumferential surface of the limiting rod A412. This design is to ensure precise matching and synchronous movement between the push rod A411 and the force-bearing rod A46, while limiting and adjusting the range of movement through the sliding connection between the threaded sleeve 44 and the limiting rod A412.

[0027] A water inlet pipe 414 is provided on the top of the cooling water pump box 45, and a rubber plug 415 is inserted into the inner side of the water inlet pipe 414. The insertion design of the rubber plug 415 into the inner side of the water inlet pipe 414 is mainly used to seal the opening of the water inlet pipe 414 to prevent water leakage.

[0028] In this embodiment, the operator adds coolant to the cooling water pump box 45 through the water inlet pipe 414. After starting the motor 42, the motor 42 drives the reciprocating screw 43 to rotate. The rotation of the reciprocating screw 43 causes the threaded sleeve 44 to reciprocate horizontally under the restriction of the limiting rod A412. The reciprocating motion of the threaded sleeve 44 causes the push rod A411 to also move horizontally, thereby pushing the force rod A46 to perform a piston-like reciprocating motion within the cooling water pump box 45. The movement of the force rod A46 propels the coolant smoothly to the main water pipe 47, and then flows into the circular water distribution plate 48 through the main water pipe 47. The design of the circular water distribution plate 48 allows the coolant to be evenly dispersed and delivered into multiple water spray pipes 49, and then further dispersed into the water spray branch pipes 410 through these water spray pipes 49, thereby achieving precise control, uniform distribution, and efficient rapid cooling of the rolled high-temperature special steel. During the cooling process, when the force-bearing rod A46 stops moving due to loss of thrust, the return spring A413 automatically resets the force-bearing rod A46 using its own elasticity, ensuring the system returns to its original state and facilitating the next cooling operation. The entire process, through precise mechanical coordination and liquid flow control, ensures stable and uniform temperature changes on the steel surface during cooling, thereby effectively improving steel quality and production efficiency.

[0029] Example 2 like Figures 1 to 7As shown, based on the same concept as Embodiment 1 above, a coolant circulation device 5 is provided on the inner bottom of the transport seat 1. The coolant circulation device 5 includes a circulating water pump box 51, the bottom of which is fixedly connected to the inner bottom of the transport seat 1. One end of the circulating water pump box 51 is fixedly connected to a water inlet pipe 52, and the other end of the water inlet pipe 52 is fixedly connected to a concave water collection tank 53. The other end of the circulating water pump box 51 is piston-slidably connected to a force-bearing rod B54. A belt A55 is provided on the circumferential surface of the reciprocating screw 43, and a belt shaft A56 is driven and connected to the circumferential surface of the reciprocating screw 43 through the belt A55. A connecting rod A57 is fixedly connected to the side of the cooling chamber 3, and one end of the connecting rod A57 rotates with the circumferential surface of the belt shaft A56. The belt shaft A56 is connected to a belt B58 on its circumference. A belt shaft B59 is connected to the circumference of belt shaft A56 via belt B58. One end of the circumference of belt shaft B59 has a reciprocating threaded groove 510. A movable sleeve 511 is threaded into the reciprocating threaded groove 510 of belt shaft B59. A push rod B512 is fixedly connected to the circumference of movable sleeve 511. A connecting rod B513 is fixedly connected to the side of transport seat 1. One end of connecting rod B513 is rotatably connected to the circumference of belt shaft B59, and the other end of connecting rod B513 is rotatably connected to a limit rod B514. A water supply pipe 515 is fixedly connected to the side of circulating water pump box 51, and the other end of water supply pipe 515 is fixedly connected to the side of cooling water pump box 45. This design allows the coolant sprayed from the rapid water cooling device 4 to be collected and transported back to cooling water pump box 45 for reuse, achieving reuse and environmental protection.

[0030] The circumferential surface of the limiting rod B514 is slidably connected to the circumferential surface of the movable sleeve 511, and one end of the force-bearing rod B54 is located on the displacement trajectory of the push rod B512. The design and cooperation of the limiting rod B514 and the force-bearing rod B54 can effectively control the force and limit the displacement while ensuring the stable operation of the system, thus ensuring the efficient and safe operation of the entire mechanical system.

[0031] A one-way valve A516 is fixedly connected to the circumference of the water supply pipe 515, a one-way valve B517 is fixedly connected to the circumference of the water inlet pipe 52, and a return spring B518 is fixedly connected to the circumference of the force-bearing rod B54. One end of the return spring B518 is fixedly connected to the other end of the circulating water pump box 51. The cooperation of these components ensures the one-way flow of water, prevents backflow, and enables the system to self-regulate and recover through the return spring B518, ensuring the stability and normal operation of the water pump and pipeline system under different working conditions.

[0032] In this embodiment, when the reciprocating screw 43 rotates, it first drives the belt A55 to rotate. The rotation of the belt A55 further drives the belt shaft A56 to rotate. As the belt shaft A56 rotates, the belt B58 also begins to rotate, and the rotation of the belt B58 in turn drives the belt shaft B59 to rotate. The rotation of the belt shaft B59 ultimately causes the movable sleeve 511 at the reciprocating thread groove 510 to reciprocate under the restriction of the limiting rod B514. The reciprocating motion of the movable sleeve 511 drives the push rod B512 to reciprocate horizontally through mechanical transmission. The movement of the push rod B512 pushes the force rod B54 to reciprocate in a piston-like manner within the circulating water pump box 51, thereby pushing the coolant connected through the water inlet pipe 52 to be delivered to the water supply pipe 515, ensuring that the coolant flows into the cooling water pump box 45 and can be recycled again.

[0033] Example 3 like Figures 1 to 7 As shown, based on the same concept as Embodiment 1 above, a cooling optimization device 6 is provided on the top of the cooling chamber 3. The cooling optimization device 6 includes a slot 61, which is formed on the top of the cooling chamber 3. A fixed shell 62 is fixedly connected to the inner side of the cooling chamber 3, and a motor 63 is fixedly connected to the inner side of the fixed shell 62. A fan blade 64 is fixedly connected to the output shaft of the motor 63. An air guide port A65 and an air guide port B66 are formed at the bottom of the fixed shell 62. Through the cooperation of the slot 61, the motor 63, and the fan blade 64, a strong airflow is provided, increasing the heat dissipation effect. The layout of the entire cooling optimization device 6 improves the cooling efficiency of the system, ensuring that the equipment is kept within a suitable temperature range during operation, thereby improving the stability and lifespan of the equipment.

[0034] The fan blade 64 directs the airflow vertically downwards, and there is a gap between the circumferential surface of the fan blade 64 and the side of the fixed shell 62. This directly propels the air downwards, enhancing the heat dissipation effect.

[0035] The air vents A65 and B66 face opposite directions and are not aligned. Multiple air vents A65 and B66 are provided and arranged in a linear array along the bottom of the fixed shell 62. This ensures uniform airflow within the cooling chamber 3, avoids dead zones and stagnant air areas, improves cooling efficiency, and makes the cooling system not only highly efficient but also more energy-efficient.

[0036] In this embodiment, after the motor 63 is started, the output shaft of the motor 63 begins to rotate, thereby driving the fan blade 64 to rotate at high speed. As the fan blade 64 rotates, air is rapidly drawn in and blown out through the air guide port A65 and air guide port B66. The ingenious design of the air guide ports A65 and B66 allows the airflow to be widely diffused within the cooling chamber 3, ensuring that every corner of the cooling chamber 3 receives uniform airflow, thus effectively avoiding dead zones that may occur during the cooling process, making the airflow-assisted cooling effect more significant. At the same time, the airflow pushes the water mist particles in the air to further exchange heat with the high-temperature steel surface.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
