Description

Technical Field

[0001] This utility model belongs to the field of rolling fluid cooling technology, and in particular relates to a temperature control and stirring device for aluminothermic rolling fluid. Background Technology

[0002] In the hot rolling process of aluminum, the rolling fluid plays a crucial role in lubrication, cooling, cleaning, and protecting the surface quality of the rolled parts. Its temperature stability directly affects the rolling process accuracy, equipment lifespan, and the final quality of aluminum products. As the aluminum processing industry develops towards higher precision and higher efficiency, the requirements for temperature control of the rolling fluid are becoming increasingly stringent. The rolling fluid must be maintained within a specific temperature range for a long period of time to ensure its effectiveness.

[0003] The inventors discovered that at least the following problems remain unresolved in the existing technology: Firstly, traditional cooling equipment often employs a fixed heat exchange structure, which can easily lead to localized stagnation of the rolling fluid within the temperature control container. This results in insufficient contact between the heat exchange tubes and the rolling fluid, leading to low cooling efficiency and significant temperature differences in different areas of the rolling fluid within the container, affecting the stability of subsequent rolling processes. Secondly, the existing devices have a simple coolant circulation path design, enabling only single-pass heat exchange. The coolant, after absorbing heat, cannot be promptly discharged and replenished with low-temperature liquid, causing the temperature difference between the inside and outside of the heat exchange tubes to rapidly decrease, resulting in a continuous decline in cooling effect. Furthermore, in some devices, the drive mechanism and circulation components are independent, resulting in a complex structural design and increased energy consumption during operation.

[0004] Therefore, we propose a temperature-controlled stirring device for hot aluminum rolling liquid, which can solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a temperature-controlled stirring device for hot aluminum rolling liquid, which has a compact structure, sufficient heat exchange, and high cooling efficiency.

[0006] In view of this, the present invention provides a temperature control and stirring device for hot alumina rolling liquid, including a temperature control cylinder, wherein a heat exchange tube is vertically arranged inside the temperature control cylinder for cooling the rolling liquid inside the temperature control cylinder, and a driving mechanism is arranged above the inside of the temperature control cylinder for stirring the rolling liquid inside the temperature control cylinder. The drive mechanism is equipped with a circulation component for the circulation of the rolling fluid inside the heat exchange tube.

[0007] Furthermore, the driving mechanism includes a servo motor for driving the heat exchange tubes to rotate, and a first connecting pipe and a second connecting pipe horizontally fixedly installed at the top and bottom of the heat exchange tubes. The heat exchange tubes are equidistantly distributed between the first connecting pipe and the second connecting pipe. A first liquid guide pipe is vertically fixedly installed in the middle of the upper surface of the first connecting pipe. The shaft end of the servo motor is fixedly connected to the top end of the first connecting pipe.

[0008] Furthermore, the upper end of the inner wall of the temperature control cylinder is fixedly connected to the outer side of the fixed base through four sets of fixed pipes, and the servo motor is fixedly connected to the upper surface of the fixed base. The dimensions of the first connecting pipe, the second connecting pipe and the heat exchange pipe are matched with the dimensions of the temperature control cylinder.

[0009] Furthermore, the circulation assembly includes an inlet pipe for conveying coolant and an annular heat exchange groove formed inside the wall of the temperature control cylinder. A first liquid guide groove is formed inside the fixed base. A second liquid guide pipe is vertically fixedly installed in the middle of the bottom side of the second connecting pipe. A second liquid guide groove is formed in the middle of the bottom wall of the temperature control cylinder. The end of the second liquid guide pipe away from the second connecting pipe is connected to the second liquid guide groove. The inlet pipe is fixedly installed in the middle of the bottom end of the temperature control cylinder. The outlet end of the inlet pipe is connected to the second liquid guide groove.

[0010] Furthermore, the two ends of the heat exchange tube are respectively connected to the first connecting pipe and the second connecting pipe, the first connecting pipe and the second connecting pipe are respectively connected to the first liquid guiding pipe and the second liquid guiding pipe, and liquid guiding ports are equidistantly opened on the outer side of the first liquid guiding pipe.

[0011] Furthermore, one end of the fixed tube that is fixedly connected to the fixed seat is connected to the first liquid guiding groove, and the other end of the fixed tube that is away from the fixed seat is connected to the heat exchange groove inside the temperature control cylinder wall.

[0012] Furthermore, the first liquid guide tube is rotatably connected to the inner wall of the first liquid guide groove via a sealed bearing, and the second liquid guide tube is rotatably connected to the second liquid guide groove via a sealed bearing.

[0013] Furthermore, a recovery pipe is fixedly installed at the bottom of one side of the temperature control cylinder, and the liquid inlet end of the recovery pipe is connected to the bottom of the heat exchange tank. A discharge pipe is installed through one side of the inner wall of the bottom of the temperature control cylinder, and valves are installed inside the liquid inlet pipe, the recovery pipe and the discharge pipe.

[0014] The beneficial effects of this utility model are: 1. A heat exchange tube is vertically installed inside the temperature control cylinder. The tube body is in full contact with the high-temperature rolling liquid inside the temperature control cylinder. Heat exchange is achieved through the temperature difference between the inside and outside of the tube, transferring the heat of the rolling liquid to the cooling liquid flowing inside the tube, completing the initial cooling of the rolling liquid. A drive mechanism at the top of the temperature control cylinder can drive the heat exchange tube to rotate, causing the rolling liquid in different areas of the temperature control cylinder to flow, avoiding insufficient heat exchange due to prolonged stagnation of the rolling liquid in some areas. The circulation component is driven by power or pressure to make the cooling liquid continuously flow inside the heat exchange tube, which can replenish the low-temperature cooling liquid. Through the annular heat exchange groove opened inside the temperature control cylinder wall, the rolling liquid in the temperature control cylinder can be cooled a second time in the cooling liquid circulation path.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1 to 4 A temperature-controlled stirring device for aluminothermic rolling liquid includes a temperature control cylinder 1, with a heat exchange tube 11 vertically arranged inside the temperature control cylinder 1 for cooling the rolling liquid inside the temperature control cylinder 1. A driving mechanism is arranged above the inside of the temperature control cylinder 1 for stirring the rolling liquid inside the temperature control cylinder 1. The driving mechanism is equipped with a circulation component for circulating the rolling liquid inside the heat exchange tube 11.

[0018] A heat exchange tube 11 is vertically installed inside the temperature control cylinder 1. The tube body is in full contact with the high-temperature rolling fluid inside the cylinder 1, and heat exchange is achieved through the temperature difference between the inside and outside of the tube. The heat of the rolling fluid is transferred to the cooling fluid flowing inside the tube, completing the initial cooling of the rolling fluid. A drive mechanism located at the top inside the temperature control cylinder 1 rotates the heat exchange tube 11, causing the rolling fluid in different areas of the cylinder 1 to flow. This prevents insufficient heat exchange due to prolonged stagnation in some areas, ensuring that all rolling fluid is in contact with the surface of the heat exchange tube 11, improving the overall cooling uniformity. During the heat exchange process with the rolling fluid, the cooling fluid inside the heat exchange tube 11 absorbs heat, causing its temperature to rise. If the cooling fluid stagnates, the cooling effect will rapidly decrease. A circulation component, driven by power or pressure, continuously circulates the cooling fluid inside the heat exchange tube 11, promptly discharging the cooled fluid after heat absorption and replenishing it with low-temperature cooling fluid, maintaining a stable temperature difference between the inside and outside of the heat exchange tube 11, and ensuring that the cooling efficiency does not decrease.

[0019] Furthermore, the driving mechanism includes a servo motor 14 for driving the heat exchange tube 11 to rotate, and a first connecting pipe 12 and a second connecting pipe 13 horizontally fixedly installed at the top and bottom of the heat exchange tube 11. The heat exchange tubes 11 are equidistantly distributed between the first connecting pipe 12 and the second connecting pipe 13. A first liquid guide pipe 15 is vertically fixedly installed in the middle of the upper surface of the first connecting pipe 12. The shaft end of the servo motor 14 is fixedly connected to the top end of the first connecting pipe 12.

[0020] When the servo motor 14 is powered on, it can drive the first connecting pipe 12 to rotate around its own axis. When the first connecting pipe 12 is driven to rotate by the servo motor 14, it will drive the second connecting pipe 13 to rotate synchronously through the traction of the heat exchange pipe 11, and finally realize the stable rotation of the entire frame unit in the temperature control cylinder 1. The rotating heat exchange pipe 11 will directly agitate the rolling liquid in the temperature control cylinder 1, forming a spiral or vortex-like fluid movement, solving the problem of rolling liquid stratification.

[0021] Furthermore, the upper end of the inner wall of the temperature control cylinder 1 is fixedly connected to the outer side of the fixed base 18 through four sets of fixed pipes 17, and the servo motor 14 is fixedly connected to the upper surface of the fixed base 18. The dimensions of the first connecting pipe 12, the second connecting pipe 13 and the heat exchange pipe 11 are matched with the dimensions of the temperature control cylinder 1.

[0022] The four sets of fixing tubes 17 are symmetrically distributed, with one end fixedly connected to the upper end of the inner wall of the temperature control cylinder 1 and the other end fixedly connected to the outer side of the fixing seat 18. This allows the fixing seat 18 to be stably suspended above the inside of the temperature control cylinder 1, preventing the fixing seat 18 from shifting or shaking due to the vibration of the servo motor 14 during operation.

[0023] Furthermore, the circulation assembly includes an inlet pipe 23 for conveying coolant and an annular heat exchange groove 24 formed inside the wall of the temperature control cylinder 1. A first liquid guide groove 2 is formed inside the fixed base 18. A second liquid guide pipe 16 is vertically fixedly installed in the middle of the bottom side of the second connecting pipe 13. A second liquid guide groove 22 is formed in the middle of the bottom wall of the temperature control cylinder 1. The end of the second liquid guide pipe 16 away from the second connecting pipe 13 is connected to the second liquid guide groove 22. The inlet pipe 23 is fixedly installed in the middle of the bottom end of the temperature control cylinder 1. The outlet end of the inlet pipe 23 is connected to the second liquid guide groove 22.

[0024] When the external supply equipment is started, the low-temperature coolant will be continuously delivered to the second liquid guide tank 22 through the liquid inlet pipe 23 to complete the initial input of coolant; the low-temperature coolant in the second liquid guide tank 22 will flow into the second connecting pipe 13 through the second liquid guide pipe 16 under the action of external pressure.

[0025] Furthermore, the two ends of the heat exchange tube 11 are respectively connected to the first connecting tube 12 and the second connecting tube 13. The first connecting tube 12 and the second connecting tube 13 are respectively connected to the first liquid guiding tube 15 and the second liquid guiding tube 16. Liquid guiding ports 21 are equidistantly opened on the outer side of the first liquid guiding tube 15. The liquid guiding ports 21 are placed in the first liquid guiding groove 2. The first liquid guiding groove 2 is connected to the first liquid guiding tube 15 through the liquid guiding ports 21.

[0026] When the coolant flows from the first connecting pipe 12 into the first liquid guide pipe 15, it will flow out radially through the liquid guide port 21 under pressure and enter the first liquid guide tank 2, completing the transfer of the coolant from the first liquid guide pipe 15 to the first liquid guide tank 2, preparing it for subsequent entry into the heat exchange tank 24.

[0027] Furthermore, one end of the fixed tube 17, which is fixedly connected to the fixed seat 18, is connected to the first liquid guiding groove 2, and the other end of the fixed tube 17, which is away from the fixed seat 18, is connected to the heat exchange groove 24 inside the wall of the temperature control cylinder 1.

[0028] A dedicated channel for coolant to flow from the first guide channel 2 to the heat exchange tank 24 is constructed via a fixed pipe 17, allowing the coolant in the first guide channel 2 to continuously flow into the heat exchange tank 24 under pressure through the fixed pipe 17. The annular heat exchange tank 24, located inside the wall of the temperature control cylinder 1, serves as a secondary heat exchange space within the coolant circulation path. Its annular structure surrounds the entire wall of the temperature control cylinder 1. When subsequent coolant flows from the first guide channel 2 into the heat exchange tank 24, the annular design ensures that the coolant is evenly distributed inside the cylinder wall, allowing for secondary heat exchange with the rolling fluid within the temperature control cylinder 1 (i.e., heat transfer through the cylinder wall), further enhancing the cooling effect. Furthermore, the first liquid guide tube 15 is rotatably connected to the inner wall of the first liquid guide groove 2 via a sealed bearing, and the second liquid guide tube 16 is rotatably connected to the second liquid guide groove 22 via a sealed bearing.

[0029] On the one hand, it can improve the rotational stability of the first liquid guide tube 15 and the second liquid guide tube 16, and on the other hand, it can prevent the coolant from leaking through the gap between the first liquid guide groove 2 and the second liquid guide groove 22 and the first liquid guide tube 15 and the second liquid guide tube 16.

[0030] Furthermore, a recovery pipe 26 is fixedly installed at the bottom of one side of the temperature control cylinder 1. The liquid inlet end of the recovery pipe 26 is connected to the bottom of the heat exchange tank 24. A discharge pipe 25 is installed through one side of the inner wall of the bottom of the temperature control cylinder 1. Valves 27 are provided inside the liquid inlet pipe 23, the recovery pipe 26 and the discharge pipe 25.

[0031] After the coolant completes secondary heat exchange in the heat exchange tank 24, the valve 27 inside the recovery pipe 26 is opened, and the coolant will flow out of the device through the recovery pipe 26 under pressure. It can be transported to external refrigeration equipment for cooling treatment, and then input back into the device through the liquid inlet pipe 23 to realize the recycling and reuse of the coolant and reduce operating costs. After the rolling liquid in the temperature control cylinder 1 reaches the preset temperature after a period of stirring and cooling, the valve 27 inside the discharge pipe 25 is opened, and the qualified rolling liquid will flow out through the discharge pipe 25 and can be transported to the aluminum hot rolling production line for continued use.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
