Technical Field

[0001] The utility model relates to the technical field of hot-rolled leather material cooling, in particular to a hot-rolled leather material rapid cooling device. Background Art

[0002] When aluminum sheets are rolled on a hot rolling mill, the final temperature of the rolled sheets will reach over 300°C. Due to the special properties of aluminum, it will soften at high temperatures, which makes it easy for adhesion to occur during the subsequent sawing process, causing the saw blade to get stuck and affecting the quality of the cut. Therefore, the sheet temperature needs to be cooled to below 150°C within a 200-meter conveyor roller. A hot-rolled sheet rapid cooling device is proposed.

[0003] In the existing technology, electric valves are not designed for segmented control, which easily causes unnecessary energy waste, is inconvenient to adjust the position and angle of the air outlet, and is not convenient to achieve a large flow of air, resulting in a waste of electric energy. In addition, in the existing technology, air supply ducts are made on the upper and lower sides of a 50-meter-long roller conveyor, which easily leads to high subsequent maintenance costs and poor practicality. Summary of the Invention

At the same time, the air amplifier uses the Coanda effect and uses a small amount of compressed air as a power source to drive the surrounding air flow to form a high-pressure, high-speed airflow. The flow rate is 50 times the air consumption. After the compressed air enters the annular cavity through the compressed air inlet 2, it flows through the annular nozzle at high speed. This airflow is adsorbed on the contour surface, thus forming a low-pressure area in the cavity, so that a large amount of surrounding air is sucked in from one side of the air amplifier and merged with the compressed air to form a high-speed, high-capacity airflow flowing out from the outlet, increasing the air flow, thereby taking away more heat and achieving rapid cooling, avoiding the production of air supply ducts on the upper and lower sides of the 50-meter-long roller conveyor, which easily leads to high maintenance costs in the later stage.
