[0002] In the production process of hot-dip galvanized aluminum-magnesium sheet and strip, the cooling process is a crucial step. A suitable cooling process can effectively control the microstructure and properties of the sheet and strip, ensuring product quality.
[0003] Currently, existing cooling devices for hot-dip galvanized aluminum-magnesium sheet and strip suffer from uneven cooling and low cooling efficiency during mass production. For example, uneven distribution of cooling air within the cooling chamber leads to inconsistent cooling rates in different parts of the sheet and strip, affecting the flatness and surface quality of the sheet and strip. Furthermore, the cooling parameters cannot be flexibly adjusted according to the actual conditions of the sheet and strip during the cooling process, making it difficult to meet the cooling requirements of different sheet and strip specifications, thus reducing production efficiency and product qualification rate.
[0004] Therefore, a batch hot-dip galvanized aluminum-magnesium upward air outlet cooling device is proposed to address the above problems. Utility Model Content
[0005] To address the problems mentioned in the background art, this utility model provides a batch hot-dip galvanized aluminum-magnesium sheet cooling device to solve the problems of uneven cooling, low cooling efficiency, and inability to flexibly adjust cooling parameters in existing cooling devices, thereby achieving efficient and uniform cooling of hot-dip galvanized aluminum-magnesium sheets and strips, and improving product quality and production efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a batch hot-dip galvanized aluminum-magnesium sheet upward air outlet cooling device, comprising a cooling box, an air inlet, an air outlet, a flow distribution component, an air inlet component, and cooling nozzles. The cooling box is rectangular in shape, with a protruding cavity at the bottom and an opening at the top. An air inlet is provided on one side of the cooling box, and an air outlet is provided on the other side. Multiple sets of cooling nozzles are installed at the lower part of the cooling box. The cooling nozzles are arranged at equal intervals along the conveying direction of the zinc-aluminum-magnesium sheet.

[0008] Preferably, a frequency converter is installed on the drive mechanism of the fan.
[0009] Preferably, a thickness detection sensor is also installed inside the cooling box, and the thickness detection sensor is electrically connected to the frequency converter and the flow control valve.
[0010] Preferably, the flow distribution assembly includes a flow distribution plate and multiple flow distribution channels. The flow distribution plate is inclined and fixedly connected to the inner wall of the cooling box. Multiple flow distribution channels are formed on the surface of the flow distribution plate, and the diameter of the flow distribution channels gradually decreases from the end near the air inlet pipe to the end away from the air inlet pipe.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 4 As shown, this utility model provides a batch hot-dip galvanized aluminum-magnesium sheet upward air outlet cooling device, including a cooling box 1, an air inlet 2, an air outlet 3, a flow distribution component 4, an air inlet component 5, and cooling nozzles 6. The cooling box 1 is rectangular in shape, with a protruding cavity at the bottom and an opening at the top. An air inlet 2 is provided on one side of the cooling box 1, and an air outlet 3 is provided on the other side. Multiple sets of cooling nozzles 6 are installed at the lower part of the interior of the cooling box 1. The cooling nozzles 6 are arranged at equal intervals along the conveying direction of the zinc-aluminum-magnesium sheet. Each cooling nozzle 6 is connected to an independent liquid supply pipeline, and a flow control valve is provided on the liquid supply pipeline. The flow distribution component 4 is located inside the cooling box 1 and at the air inlet. The air inlet component 5 is located outside the air inlet of the cooling box 1.
[0023] The cooling box 1 is rectangular in shape, with a protruding cavity at the bottom and an opening at the top. This structural design facilitates the conveying of the strip and the flow of the cooling medium. An air inlet 2 is provided on one side of the cooling box 1, and an air outlet 3 is provided on the other side, forming a flow channel for cooling air. Multiple sets of cooling nozzles 6 are installed at the lower part of the interior of the cooling box 1. These cooling nozzles 6 are arranged at equal intervals along the conveying direction of the zinc-aluminum-magnesium sheet and strip. Each cooling nozzle 6 is connected to an independent liquid supply pipeline, and a flow control valve is installed on the liquid supply pipeline. The flow control valve can precisely control the liquid supply of each cooling nozzle, thereby achieving precise adjustment of the cooling intensity of different parts of the sheet and strip. In conjunction with the flow distribution component 4, this design enables the cooling air entering the cooling box 1 to be evenly distributed according to the change of the diameter of the flow distribution channel 42 under the action of the flow distribution plate 41, ensuring the uniform distribution of cooling air in the cooling box 1, thereby achieving uniform cooling of the sheet and strip. The air inlet component 5 is added, and the fan 51 sends the outside air into the cooling box 1 to provide a cooling air source for the cooling process.
[0024] like Figures 1 to 4As shown, the air intake assembly 5 includes a fan 51 and an air intake pipe 52. The fan 51 is installed outside the cooling box 1. One end of the air intake pipe 52 is connected to the air outlet of the fan 51, and the other end of the air intake pipe 52 passes through the air inlet and communicates with the inside of the cooling box. The fan 51 draws in outside air and sends it into the cooling box 1 through the air intake pipe 52, providing a cooling air source for the cooling process.
[0025] It should be noted that a frequency converter 7 is installed on the drive mechanism of the fan 51. The speed of the fan 51 can be adjusted by the frequency converter 7, thereby controlling the cooling air volume entering the cooling box 1 to meet different cooling needs.
[0026] The cooling box 1 is also equipped with a thickness detection sensor 8. The thickness detection sensor 8 is electrically connected to the frequency converter 7 and the flow control valve. The thickness detection sensor 8 can detect the thickness of the strip in real time. According to the change in the thickness of the strip, the signal is transmitted to the frequency converter 7 and the flow control valve. The frequency converter 7 automatically adjusts the fan speed, and the flow control valve automatically adjusts the liquid supply of the cooling nozzle 6, so as to realize the automatic and precise adjustment of the cooling parameters and ensure that strips of different thicknesses can get the best cooling effect.
[0027] like Figures 1 to 4 As shown, the flow distribution assembly 4 includes a flow distribution plate 41 and multiple flow distribution channels 42. The flow distribution plate 41 is inclined and fixedly connected to the inner wall of the cooling box 1. Multiple flow distribution channels 42 are opened on the surface of the flow distribution plate 41. The diameter of the flow distribution channels 42 gradually decreases from the end near the air inlet pipe to the end away from the air inlet pipe. This design enables the cooling air entering the cooling box 1 to be evenly distributed according to the change in the diameter of the flow distribution channels 42 under the action of the flow distribution plate 41, ensuring the uniform distribution of cooling air in the cooling box 1, thereby enabling the plate and strip to be uniformly cooled.
[0028] Working principle and process: In practical applications, the hot-dip galvanized aluminum-magnesium sheet to be cooled is fed into the cooling box 1 through the top opening, and the sheet moves inside the cooling box 1 along the conveying direction. The fan 51 is started, and the fan 51 sends outside air into the cooling box 1 through the air inlet pipe 52. When the air passes through the diversion component 4, it is evenly distributed inside the cooling box 1 under the action of the diversion plate 41 and the diversion channel 42.
[0029] After the thickness sensor detects the thickness of the strip, it transmits the signal to the frequency converter 7 and the flow control valve. If the strip is thicker and requires stronger cooling, the frequency converter 7 will automatically increase the speed of the fan 51 to increase the cooling airflow, while the flow control valve will increase the liquid supply of the cooling nozzle 6. Conversely, if the strip is thinner, the frequency converter 7 will reduce the speed of the fan 51 to reduce the cooling airflow, and the flow control valve will reduce the liquid supply of the cooling nozzle.
[0030] The cooling air and the coolant sprayed from the cooling nozzles 6 work together to cool the strip. The cooled hot air and coolant are then discharged from the cooling chamber, completing the cooling process for the hot-dip galvanized aluminum-magnesium strip. Throughout the cooling process, real-time monitoring and automatic adjustment ensure that the strip receives efficient and uniform cooling to meet production requirements.
