[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example

[0026] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 4, 5, and 6, a rapid cooling device for steel rolling includes a base 10. A cooling box 11 is fixedly installed on one side of the top of the base 10, and a condenser 12 is installed on the other side of the top of the base 10. Multiple bottom brush rollers 13 are rotatably installed at the bottom of the cooling box 11. Multiple first side brush rollers 14 are rotatably installed on one side of the interior of the cooling box 11, and multiple second side brush rollers 15 are movably installed on the other side of the interior of the cooling box 11. An installation plate 16 is suspended at the top of the interior of the cooling box 11. A lifting component 17 is provided at the top of the cooling box 11 to connect to the installation plate 16. Multiple top brush rollers 18 are rotatably suspended at the bottom of the installation plate 16. A spray component 19 is installed at the top of the condenser 12. Two connecting gears 131 are provided at one end of the bottom brush rollers 13, and one connecting gear 131 is provided at one end of the first and last bottom brush rollers 13. Adjacent connecting gears 131 is alternately connected by toothed belt 132. The base 10 is equipped with a first motor 133 on the top and the first motor 133 is connected to the central shaft of a bottom brush roller 13. The cooling box 11 has anti-leakage sealing plates 111 at both ends. The first side brush roller 14 and the second side brush roller 15 are aligned front and back. The top brush roller 18 and the middle multiple bottom brush rollers 13 are aligned vertically. The first side brush roller 14 and the bottom brush roller 13 are staggered left and right. The spray component 19 includes a pump 191 installed on the top of the condenser 12. The pump 191 has a first water guide pipe 192 connected to the water outlet of the condenser 12 at the input end. The bottom of one end of the condenser 12 has a second water guide pipe 193 connected to the bottom of the cooling box 11. Multiple spray heads 194 are installed at the bottom of the mounting plate 16. The pump 191 has a third water guide pipe 195 connected to each spray head 194 at the output end.

[0027] As described above, the alternating connection of each connecting gear 131 via toothed belt 132 enhances the stability of the gear connection and prevents the intermediate bottom brush roller 13 from disengaging due to insufficient driving force. Steel is fed into the cooling box 11 from one end via an external device. The first motor 133 starts, driving one bottom brush roller 13 to rotate. Through the alternating connection of each connecting gear 131 and toothed belt 132, all bottom brush rollers 13 rotate synchronously, thus propelling the steel forward. Cold water, slightly lower than the top of the bottom brush roller 13, accumulates at the bottom of the cooling box 11. This cold water is sealed at the bottom of the cooling box 11 by a leak-proof sealing plate 111 to prevent leakage. As the bottom brush roller 13 rotates, propelling the steel forward, it simultaneously circulates into the cold water, coating the bottom of the steel. The bottom of the steel is cooled rapidly. At the same time, the pump 191 draws freshly condensed water from inside the condenser 12. The water pressure causes the water accumulated at the bottom of the cooling box 11 to enter the condenser 12 through the second water pipe 193 for condensation. The pump 191 sprays the drawn cold water into the cooling box 11 through the third water pipe 195 using multiple spray nozzles 194. While cooling the steel, the first side brush roller 14, the second side brush roller 15, and the top brush roller 18 are simultaneously soaked, so that the cold water is evenly applied to both sides and the top of the steel, achieving rapid cooling of the steel from multiple sides at the same time. Excess cold water falls into the bottom of the cooling box 11. When the water level of the cold water accumulated at the bottom of the cooling box 11 drops, it can be directly replenished into the cooling box 11 by external scooping.

[0028] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 3 and 5, the upper and lower ends of the second side brush roller 15 are rotatably connected to a C-shaped frame 151. The side plate of the C-shaped frame 151 slides through the side wall of the cooling box 11. A first threaded sleeve 152 is fixedly provided in the middle of the C-shaped frame 151. The first threaded sleeve 152 is connected to a first threaded rod 153 by a nut inside. One end of the first threaded rod 153 is rotatably installed on the side wall of the cooling box 11, and the other end is fixedly installed with a rotating handle 154. The lifting component 17 includes a second motor 171 installed at one end of the top of the cooling box 11. The actuating end of the second motor 171 is connected to a double-output gear reducer 172. The two output ends of the double-output gear reducer 172 are connected to two... A second threaded rod 173 is fixedly mounted on the other end of the top of the cooling box 11, and a limit plate 174 is fixedly installed on the other end of the second threaded rod 173. The other end of the second threaded rod 173 is rotatably mounted on the limit plate 174. A scissor lift 161 is mounted on the top of the mounting plate 16. The top and bottom of one end of the scissor lift 161 are respectively hinged to the bottom of the limit plate 174 and the top of the mounting plate 16. The bottom of the other end of the scissor lift 161 is slidably mounted on the top of the mounting plate 16. Two second threaded cylinders 162 are hinged to the top of the other end of the scissor lift 161. The second threaded cylinders 162 are connected to the second threaded rod 173 with nuts. Two strip grooves 163 for the operation of the scissor lift 161 are opened on the top of the cooling box 11.

[0029] When the steel materials of different sizes need to be rapidly cooled, the rotating handle 154 can be twisted in sequence, the first threaded sleeve 152 can be driven to move by the first threaded rod 153, the C-shaped frame 151 can slide in the middle of the cooling box 11, the distance between the second side brush roller 15 and the first side brush roller 14 can be adjusted, the width of the steel material that can be brushed on both sides at the same time can be adjusted, the second motor 171 is started, the double-output gear reducer 172 drives the two second threaded rods 173 to rotate synchronously, the one end top of the scissors frame 161 is driven to move forward and backward by the thread nut, the scissors frame 161 is driven to fold and separate, the mounting plate 16 is driven to lift, the multiple top brush rollers 18 are adjusted to lift, the relative height between the top brush roller 18 and the bottom brush roller 13 is changed, and the thickness of the steel material that can be brushed up and down at the same time is adjusted.

[0030] The above examples only illustrate the technical idea of the present application, and cannot limit the protection scope of the present application. Any modification made on the basis of the technical idea of the present application and the technical scheme falls within the protection scope of the present application.
