It is mainly used in the manufacture of mechanical parts, automotive components, and building structural parts. The circular cross-section of round steel strip gives it good performance in terms of bearing pressure and tension. During the production process of round steel strip, some structural defects, such as banded structures, may be encountered.

[0003] In existing technologies, high-pressure water is often used to quickly cool hot-rolled steel strips. However, when the high-pressure water comes into contact with the surface of the steel strip, the water source will splash, which means that the water source cannot be continuously maintained on the surface of the steel strip. In addition, the heat of the steel strip itself will also cause the water to evaporate quickly, affecting the cooling efficiency.

[0004] Therefore, it is necessary to propose an efficient cooling system to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency cooling system to solve the problem that in the prior art, high-pressure water is often used to quickly cool hot-rolled steel strips, but when the high-pressure water comes into contact with the surface of the steel strip, the water source will splash, which makes it impossible to maintain the water source on the surface of the steel strip continuously, and the heat of the steel strip itself will also cause the water to evaporate quickly, affecting the cooling efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency cooling system, comprising a conveying unit, a detection unit, a controller, and a rapid cooling unit, wherein the detection unit, the controller, and the rapid cooling unit are all mounted on the conveying unit, and the detection unit and the controller are signal-connected, and the controller and the rapid cooling unit are signal-connected.

[0007] The conveying unit includes a conveying frame, and multiple conveying rollers are rotatably connected inside the conveying frame along its length. The rapid cooling unit includes a protective plate, which is fixed to both sides inside the conveying frame and positioned above the conveying rollers. A gap is left between the conveying rollers and the protective plate for the steel strip to pass through.

[0008] The top of the protective plate has a through groove, and a rotating plate is rotatably connected in the through groove. Multiple first nozzles are installed at the bottom of the rotating plate, and a scraper is telescopically installed on one side of the bottom of the protective plate.

[0009] Preferably, an electric push rod is fixedly connected to the top of the rotating plate, and a telescopic end is provided at the bottom of the electric push rod. The telescopic end passes through the protective plate and is fixedly connected to the bottom of the passing end and the top of the scraper.

[0010] Preferably, a bottom support plate is provided between two adjacent conveying rollers, and a plurality of second nozzles are provided at the top of the bottom support plate. The height of the plurality of second nozzles is lower than the height of the conveying rollers, and the bottom support plate is fixed to both sides inside the conveying frame.

[0011] Preferably, an air trough is provided on one side of the bottom end of the conveyor frame, and a fan is fixed at the bottom end of the air trough.

[0012] Preferably, multiple rapid cooling units are provided, and the multiple rapid cooling units are distributed at equal distances along the length direction of the conveyor frame.

[0013] Preferably, the detection unit includes a temperature sensor and a humidity sensor.

[0014] Preferably, the top of the rotating plate is connected to a connecting pipe, the connecting pipe is connected to multiple first nozzles, and the top of the conveyor frame is provided with a protective cover.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. In the actual operation of this utility model, when the steel strip passes through the protective plate, the top of the steel strip is protected by the blocking effect of the protective plate, preventing the steel strip from bending and bulging. At the same time, multiple first nozzles spray high-pressure water to cool the surface of the steel strip. The water is sprayed at an inclined angle onto the surface of the steel, effectively removing the vapor film and residual water on the surface of the steel, allowing the fresh water to come into direct contact with the high-temperature steel strip and forming an orderly wall flow on the surface of the steel. This greatly improves the heat exchange efficiency and uniformity between the steel strip and the cooling water, effectively increasing the cooling rate. At the same time, thanks to the blocking effect of the protective plate, water splashing is prevented, keeping the water on the surface of the steel strip. Since multiple rapid cooling units are provided.

[0017] 2. Furthermore, as the steel strip continues to move, the cooled surface of the steel strip will come into contact with the scraper, thereby removing excess moisture and impurities. Simultaneously, the scraper prevents high-pressure water from splashing outwards, effectively intercepting the water source.

[0018] 3. In the actual operation of this utility model, the conveying unit is used to convey steel strips, but when the steel strips that need to be cooled are moved and transported in the conveying frame, the detection unit detects the temperature of the steel strips and controls the fast cooling unit to quickly cool the steel strips through the controller.

[0019] 4. Multiple second nozzles can cool the lower surface of the steel strip, maintaining the stability of the steel strip cooling. An air trough is provided on one side of the bottom of the conveyor frame, and a fan is fixed at the bottom of the air trough to accelerate the cooling of the steel strip and the evaporation of excess moisture.

The controller and rapid cooling unit 6 are signal connected. The conveying unit includes a conveying frame 1, and multiple conveying rollers 3 are rotatably connected inside the conveying frame 1 along the length direction. The detection unit includes a temperature sensor and a humidity sensor.

[0026] In the actual operation of this utility model, the conveying unit is used to convey steel strips, but when the steel strips that need to be cooled are moved and transported in the conveying frame 1, the detection unit detects the temperature of the steel strips and controls the fast cooling unit 6 to quickly cool the steel strips through the controller.

[0027] Multiple rapid cooling units 6 are provided, and the multiple rapid cooling units 6 are distributed at equal distances along the length direction of the conveyor frame 1.

[0028] Since multiple rapid cooling units 6 are set on the moving path of the steel strip, the cooling speed can be accelerated by increasing the number of them.

[0029] The rapid cooling unit 6 includes a protective plate 7, which is fixed to both sides inside the conveyor frame 1 and is positioned above the conveyor roller 3. A gap is left between the conveyor roller 3 and the protective plate 7 for the steel strip to pass through.

[0031] In the actual operation of this utility model, when the steel strip passes through the protective plate 7, the top of the steel strip is protected and blocked by the protective plate 7, preventing the steel strip from bending and bulging. At the same time, multiple first nozzles 10 spray high-pressure water to cool the surface of the steel strip. The water is sprayed at an inclined angle onto the surface of the steel, effectively removing the vapor film and residual water on the surface of the steel. This allows the fresh water to come into direct contact with the high-temperature steel strip and forms an orderly wall flow on the surface of the steel, thereby greatly improving the heat exchange efficiency and uniformity between the steel and the cooling water. At the same time, thanks to the blocking effect of the protective plate 7, water splashing is prevented, and the water is always kept on the surface of the steel strip.

[0032] Furthermore, as the steel strip continues to move, the cooled surface of the steel strip will come into contact with the scraper 11, thereby removing excess moisture and impurities. Simultaneously, the scraper 11 prevents high-pressure water from splashing outwards, effectively intercepting the water source.

[0033] An electric push rod 12 is fixedly connected to the top of the rotating plate 9. The bottom of the electric push rod 12 is provided with a telescopic end. The telescopic end passes through the protective plate 7 and is fixedly connected to the bottom of the end and the top of the scraper 11. The extension and retraction of the electric push rod 12 can control the scraper 11 to go up and down.

[0034] A bottom support plate 13 is provided between two adjacent conveyor rollers 3. Multiple second nozzles 14 are provided at the top of the bottom support plate 13. The height of the multiple second nozzles 14 is lower than the height of the conveyor rollers 3. The bottom support plate 13 is fixed to both sides inside the conveyor frame 1. The multiple second nozzles 14 can cool the lower surface of the steel strip and maintain the stability of the cooling of the steel strip.

[0035] A duct 4 is provided on one side of the bottom of the conveyor frame 1, and a fan 5 is fixed at the bottom of the duct 4 to accelerate the cooling of the steel belt and the evaporation of excess moisture.

[0036] The top of the rotating plate 9 is connected to a connecting pipe 15, which is connected to multiple first nozzles 10. The top of the conveyor frame 1 is equipped with a protective cover 2, which is used to protect the top of the conveyor 1 and at the same time prevents excess water from splashing out, protects the steel belt, and prevents personnel from directly contacting the steel belt.
