[0026] It is understandable that, referring to Figures 1 to 3The steel material cooling device of the utility model comprises a conveying mechanism 100, a water cooling mechanism 200 and an air cooling mechanism 300. The conveying mechanism 100 comprises a driving roller 110 and a plurality of guide rollers 120. The driving roller 110 is used for winding the steel material, and the plurality of guide rollers 120 cooperate to guide the movement of the steel material. The water cooling mechanism 200 comprises a cooling box 210 and a plurality of nozzles 220. The cooling box 210 is provided with an inner cavity 211 for accommodating the steel material. The plurality of nozzles 220 are all arranged in the inner cavity 211. The nozzles 220 are used for spraying cooling water to the steel material. The air cooling mechanism 300 comprises a collecting box 310, a fan 320 and two scrapers 330. The scrapers 330 and the fan 320 are arranged along the conveying direction of the steel material. The two scrapers 330 are respectively arranged on both sides of the steel material. The collecting box 310 is arranged below the scrapers 330 to receive cooling water. The fan 320 is used for conveying airflow to the steel material.

[0027] The steel is output to the guide roller 120, the guide roller 120 receives the steel, and the guide rollers 120 guide the steel to the driving roller 110, and the driving roller 110 drives the steel to move, so that the steel can pass through the inner cavity 211, and the steel can be wound into a steel coil. Multiple nozzles 220 are arranged in the inner cavity 211, and the steel can pass through the inner cavity 211, so that the nozzles 220 can spray cooling water to the steel, thereby absorbing the heat of the steel and accelerating the heat dissipation of the steel. The two scrapers 330 They are arranged on both sides of the steel respectively, and the scraper 330 is arranged to abut against the surface of the steel so that the scraper 330 can scrape off the cooling water on the surface of the steel, and the cooling water scraped off by the scraper 330 can be collected by the collection box 310, and then the fan 320 transports airflow to the steel, which can accelerate the circulation of air, speed up the heat dissipation of the steel, and avoid blowing away the cooling water on the surface of the steel, so as to facilitate the reuse of cooling water, reduce the consumption of cooling water, improve the heat dissipation efficiency of the steel, facilitate the winding of the steel, and improve the packaging efficiency.

[0028] It should be noted that the inner bottom wall of the collection box 310 is arranged to be inclined and is connected to a joint so that the cooling water in the collection box 310 can easily move to the joint, thereby facilitating the discharge of the cooling water in the collection box 310 through the joint, facilitating the reuse of the cooling water and reducing the cost of use.

[0029] It is understandable that, referring to Figure 1 and Figure 3The cooling box 210 is provided with two sets of guide assemblies 230, which are respectively arranged at the input end and the output end of the inner cavity 211, and the guide assemblies 230 include two guide rollers 231, which are respectively arranged at both sides of the steel. The two sets of guide assemblies 230 are respectively arranged at the input end and the output end of the inner cavity 211, and the guide assemblies 230 include two guide rollers 231, which can clamp the steel together, and the position of the steel can be conveniently limited by the two sets of guide assemblies 230, and the steel can pass through the inner cavity 211 smoothly, avoiding the collision between the steel and the inner wall of the inner cavity 211, and improving the transportation stability of the steel.

[0030] Specifically, refer to Figure 1 and Figure 3 The inner bottom wall of the cooling box 210 is set as an inclined surface to guide the cooling water to the guide roller 231 near the output end of the inner cavity 211. The inner bottom wall of the cooling box 210 is set as an inclined surface so that the cooling water in the cooling box 210 can flow along the inner wall of the cooling box 210, thereby guiding the cooling water to the guide roller 231 near the output end of the inner cavity 211, and then the cooling water can be transported to the surface of the steel through the guide roller 231, so that the cooling water can continuously cool the steel and improve the cooling efficiency of the steel. Moreover, the cooling water can be evenly distributed on the surface of the steel, reducing the splashing of cooling water, reducing the consumption of cooling water, and accelerating the cooling speed of the steel.

[0031] It is understandable that, referring to Figure 3 The upper end of the cooling box 210 is provided with a plurality of through holes 212, and the plurality of through holes 212 are arranged at intervals. The plurality of through holes 212 are arranged at intervals at the upper end of the cooling box 210. By providing the through holes 212, the air pressure of the inner cavity 211 and the outside can be balanced, the deformation of the cooling box 210 can be reduced, and the reliability of the cooling box 210 can be improved. In addition, the water vapor in the inner cavity 211 can be conveniently discharged through the through holes 212, the temperature of the inner cavity 211 can be reduced, and the cooling efficiency of the steel can be improved.

[0032] It should be noted that the temperature of the steel is relatively high. When the nozzle 220 sprays cooling water onto the steel, the cooling water can evaporate into water vapor. By setting the through hole 212, the water vapor can be discharged to avoid the accumulation of water vapor in the inner cavity 211, thereby reducing the temperature of the inner cavity 211 and accelerating the cooling speed of the steel.

[0033] It is understandable that, referring to Figure 1 and Figure 2The air cooling mechanism 300 further includes a connecting frame 340, and the scraper 330 is rotatably connected to the connecting frame 340. A spring 350 is provided between the connecting frame 340 and the scraper 330. The spring 350 is used to drive the scraper 330 to rotate so that the scraper 330 can abut against the steel material. The scraper 330 is rotatably connected to the connecting frame 340 so that the scraper 330 can rotate around the hinge point, so that the position of the scraper 330 can be easily adjusted. One end of the spring 350 abuts against the connecting frame 340, and the other end of the spring 350 abuts against the scraper 330. The spring 350 can drive the scraper 330 to rotate in a direction close to the steel material, so that the scraper 330 can abut against the surface of the steel material, and then the scraper 330 can scrape the cooling water on the surface of the steel material, so as to prevent the fan 320 from blowing away the cooling water on the surface of the steel material, so as to facilitate the reuse of cooling water, reduce the consumption of cooling water, and reduce costs.

[0034] Specifically, refer to Figure 1 and Figure 2 The scraper 330 is connected with a plurality of heat dissipation fins 331, and the plurality of heat dissipation fins 331 are arranged at intervals. The scraper 330 is connected with a plurality of heat dissipation fins 331, and the plurality of heat dissipation fins 331 are arranged at intervals so that the heat in the steel can be transferred to the scraper 330, and then the plurality of heat dissipation fins 331 accelerate the heat dissipation of the scraper 330, and avoid the heat accumulation in the scraper 330, so as to facilitate the heat dissipation of the steel and improve the cooling efficiency of the steel.

[0035] It should be noted that since the spring 350 drives the scraper 330 to abut against the surface of the steel, the scraper 330 easily generates heat due to friction with the steel, and the heat in the steel is also easily transferred to the scraper 330. By providing a plurality of heat dissipation fins 331 arranged at intervals on the scraper 330, the heat dissipation of the scraper 330 can be accelerated, thereby accelerating the cooling of the steel.

[0036] It is understandable that, referring to Figure 1 and Figure 2 The end of the scraper 330 is configured to be semi-cylindrical. By configuring the end of the scraper 330 to be semi-cylindrical, the contact area between the scraper 330 and the steel material can be reduced, the wear between the scraper 330 and the steel material can be reduced, the temperature of the scraper 330 can be reduced, the cooling of the steel material can be facilitated, and the cooling efficiency of the steel material can be improved.

[0037] It is understandable that, referring to Figure 1The fan 320 is connected to an air guide cover 323, and the cross section of the air guide cover 323 gradually decreases in the direction away from the fan 320. The fan 320 is connected to the air guide cover 323, and the cross section of the air guide cover 323 is gradually reduced in the direction away from the fan 320, so that the speed of the airflow output by the fan 320 can be gradually increased from the input end to the output end of the air guide cover 323, so that the airflow can accelerate the heat dissipation of the steel and improve the cooling efficiency of the steel.

[0038] It should be noted that the fan 320 includes a motor 321 and fan blades 322, the fan blades 322 are fixedly connected to the output end of the motor 321, and the fan blades 322 are located at the input end of the air guide hood 323. The fan blades 322 are driven to rotate by the motor 321, so that the fan blades 322 can drive the air to move in the air guide hood 323, thereby enabling the airflow to be output from the air guide hood 323.

[0039] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
