Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron alloy production, and in particular to a cooling device for neodymium iron boron alloy production. Background Technology

[0002] Neodymium iron boron (NdFeB) alloy is a high-performance permanent magnet material with extremely high magnetic energy product and coercivity, and is widely used in electronics, machinery, automotive, aerospace and other fields. In the production process of NdFeB alloys, the cooling of the molten alloy is crucial.

[0003] Traditional cooling methods typically employ simple water or air cooling, but these methods suffer from low cooling efficiency, inaccurate temperature control, and the tendency for impurities to accumulate in the cooling pipes, resulting in poor cooling performance and impacting alloy performance and production efficiency.

[0004] Therefore, it is necessary to propose a cooling device for the production of NdFeB alloys to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for the production of NdFeB alloys, which solves the problems of traditional cooling methods, which usually use simple water cooling or air cooling, but these methods have problems such as low cooling efficiency, inaccurate temperature control, and easy accumulation of impurities in the cooling pipes, resulting in poor cooling effect and affecting the performance of the alloy and production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for the production of NdFeB alloys, comprising:

[0007] Support frame;

[0008] A fixing frame is provided on one side of the support frame;

[0009] The top of the support frame is equipped with a heat dissipation mechanism;

[0010] The fixing frame has an outer pipe for conveying coolant inside, and an inner pipe for conveying alloy liquid is provided inside the outer pipe. The two ends of the outer pipe are sealed, and the outer sides of the two ends of the outer pipe are respectively connected to the liquid inlet and the liquid outlet.

[0011] Preferably, a lead screw is rotatably connected between the two ends inside the fixing frame, and a movable scraper is threaded onto the outer side of the lead screw;

[0012] The top and bottom of the fixed frame are provided with sliding grooves along the length direction, and the upper and lower ends of the movable scraper are fixed with sliders, which slide and engage in the corresponding sliding grooves respectively.

[0013] Preferably, a second motor is fixed to one side of the fixing frame, and the drive shaft of the second motor is fixedly connected to one end of the lead screw.

[0014] Preferably, the heat dissipation mechanism includes a first motor, which is fixed to the top of the support frame, and fan blades are connected to the outside of the drive shaft of the first motor.

[0015] The fan blades face the fixed frame.

[0016] Preferably, the outer tube is bent back and forth and disposed between the two sides inside the fixing frame.

[0017] Preferably, the movable scraper has a sliding hole for the outer tube to slide through.

[0018] Preferably, a temperature sensor is fixed inside the mounting bracket.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] 1. The outer tube, bent back and forth, is positioned between the two sides inside the fixed frame, increasing the contact area and heat exchange path between the coolant and the alloy liquid, thus improving cooling efficiency and making the device more compact. The inner tube is used to transport the NdFeB alloy liquid. A certain gap exists between the inner and outer tubes, allowing the coolant to flow within this gap, thereby achieving effective cooling of the alloy liquid.

[0021] 2. When the lead screw rotates, it can drive the moving scraper to move along the length of the fixed frame. When the second motor starts, the moving scraper moves and can clean the outer wall of the inner tube during the movement. This prevents impurities or residues generated during the cooling process of the alloy liquid from adhering to the tube wall, or water vapor from adhering to the outer wall during the heat exchange process, which would affect the heat exchange effect and subsequent production process.

[0022] 3. The fan blades rotate, generating airflow to assist in cooling the outer tube and coolant inside the mounting frame. This helps to further reduce the coolant temperature, improve the overall cooling effect of the cooling device, and ensure that the NdFeB alloy liquid can be cooled and solidified at a suitable temperature.

[0028] This utility model provides, for example Figures 1-4 A cooling device for the production of neodymium iron boron alloys is shown, comprising: a support frame 1, made of a high-strength metal material, such as steel, to ensure that it can withstand a certain weight and external force.

[0029] The fixing frame 4 is located on one side of the support frame 1. The top of the support frame 1 is equipped with a heat dissipation mechanism. The support frame 1 is used to support the heat dissipation mechanism.

[0030] The frame 4 has an outer pipe 10 for conveying coolant inside. The outer pipe 10 has an inner pipe 11 for conveying alloy liquid inside. The two ends of the outer pipe 10 are sealed, and the outer sides of the two ends of the outer pipe 10 are respectively connected to the liquid inlet 12 and the liquid outlet 5.

[0031] The outer tube 10 is sealed at both ends to ensure that the coolant will not leak. The outer sides of both ends are connected to the inlet 12 and the outlet 5, respectively. The coolant enters the outer tube 10 from the inlet 12, and after heat exchange with the alloy liquid in the inner tube 11, it is discharged from the outlet 5, carrying away the heat.

[0032] The inner tube 11 is used to transport NdFeB alloy liquid. There is a certain gap between it and the outer tube 10, which allows the coolant to flow in the gap, thereby achieving effective cooling of the alloy liquid.

[0033] The outer tube 10 is bent back and forth between the two sides inside the fixed frame 4, which increases the contact area and heat exchange path between the coolant and the alloy liquid, improves the cooling efficiency, and also makes the structure of the device more compact.

[0034] A lead screw 9 is rotatably connected between the two ends inside the fixed frame 4. A movable scraper 8 is threaded on the outside of the lead screw 9. When the lead screw 9 rotates, it can drive the movable scraper 8 to move along the length of the fixed frame 4. When the second motor 6 is started, the movable scraper 8 moves. During the movement, it can clean the outer wall of the inner tube 11 to prevent impurities or residues generated during the cooling process of the alloy liquid from adhering to the tube wall, or water vapor from adhering to the outer wall during the heat exchange process, which would affect the heat exchange effect and subsequent production process.

[0035] The top and bottom of the fixed frame 4 are provided with sliding grooves 7 along the length direction. The upper and lower ends of the movable scraper 8 are fixed with sliders, and the two sliders slide and engage in the corresponding sliding grooves 7 respectively.

[0036] A second motor 6 is fixed to one side of the fixed frame 4, and the drive shaft of the second motor 6 is fixedly connected to one end of the lead screw 9.

[0037] The heat dissipation mechanism includes a first motor 2, which is fixed to the top of the support frame 1. A fan blade 3 is connected to the outside of the drive shaft of the first motor 2, and the fan blade 3 faces the fixed frame 4.

[0038] When the first motor 2 is working, it drives the fan blades 3 to rotate, generating airflow that assists in cooling the outer tube 10 and the coolant inside the mounting frame 4. This helps to further reduce the temperature of the coolant, improve the overall cooling effect of the cooling device, and ensure that the NdFeB alloy liquid can be cooled and solidified at a suitable temperature.

[0039] The movable scraper 8 has sliding holes for the outer tube 10 to slide through. A temperature sensor is fixed inside the fixed frame 4 to monitor the temperature of the outer tube 10 in real time. By connecting the temperature sensor to an external control system, the operating status of the first motor 2 and the second motor 6 can be automatically adjusted based on the monitored temperature data, or the flow rate of the coolant can be controlled, thereby achieving precise control of the cooling process and ensuring the quality of NdFeB alloy production.
