Description

Technical Field

[0001] This utility model relates to the field of atomizing nozzles, and in particular to an atomizing nozzle for preparing magnets. Background Technology

[0002] In the magnet manufacturing process, the atomizing nozzle is a key piece of equipment for atomizing raw materials, and its performance directly affects the microstructure and final properties of the magnet. Traditional atomizing nozzles have many problems in application and cannot meet the requirements for high-quality magnet manufacturing.

[0003] In terms of heat dissipation, traditional nozzles rely heavily on natural cooling, which is inefficient. During magnet manufacturing, the nozzle generates a significant amount of heat during high-pressure, high-speed material injection. If this heat cannot be dissipated in time, it can lead to excessively high nozzle temperatures, causing deformation, accelerated wear, and shortening the nozzle's lifespan. Furthermore, localized overheating can affect the atomization of the raw material, resulting in uneven atomized particles and ultimately impacting the consistency of the magnet's performance.

[0004] Therefore, it is necessary to propose an atomizing nozzle for preparing magnets to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an atomizing nozzle for preparing magnets, in order to solve the problem that during the preparation of magnets, the nozzle head generates a lot of heat during the high-pressure, high-speed material injection process. If the heat cannot be dissipated in time, it will lead to excessively high nozzle head temperature, which in turn will cause nozzle head deformation and accelerated wear.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an atomizing nozzle for preparing magnets, comprising a nozzle head and a connecting pipe, wherein the nozzle head and the connecting pipe are connected, a heat-conducting sleeve is fixed to the outside of the nozzle head, and a supporting shell is provided on the outside of the connecting pipe;

[0007] The supporting housing is rotatably connected to a U-shaped seat on the side near the nozzle head. The heat-conducting sleeve is disposed inside the U-shaped opening of the U-shaped seat, and a cooling fan is fixed on the side of the U-shaped seat away from the nozzle head. A ventilation opening is provided inside the U-shaped opening, and the ventilation opening is connected to the air outlet of the cooling fan.

[0008] Preferably, a rotating gear is rotatably connected to the outside of the nozzle head, and a connecting rod is fixed to the side of the rotating gear away from the connecting pipe. One end of the connecting rod is connected to a U-shaped seat, and the rotating gear cooperates with the drive mechanism.

[0009] Preferably, the driving mechanism includes a rotating shaft, which is rotatably connected to the support housing. One end of the rotating shaft near the heat-conducting sleeve extends out of the support housing, and a driving gear is fixed to the outside of the extended end.

[0010] A drive motor is fixed to the other side of the supporting housing. The drive shaft of the drive motor is connected to the rotating shaft, and the drive gear meshes with the rotating gear.

[0011] Preferably, the outer side of the heat-conducting sleeve is provided with multiple heat dissipation grooves, which penetrate the inner side of the heat-conducting sleeve.

[0012] Preferably, the air outlet of the cooling fan is oriented towards the heat-conducting jacket.

[0013] Preferably, a temperature sensor is embedded in the side of the U-shaped seat facing the heat-conducting sleeve.

[0014] Preferably, the outer side of the nozzle head and the inner ring of the rotating gear are connected by a bearing.

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

[0016] 1. A heat-conducting sleeve is fixed to the outside of the nozzle head. The heat-conducting sleeve is made of copper and has multiple heat dissipation grooves on its outer side, which penetrate the inner side of the heat-conducting sleeve. This allows the heat generated by the nozzle head during operation to be quickly transferred to the surface of the heat-conducting sleeve through the heat dissipation grooves, while also protecting the outside of the nozzle head.

[0017] 2. When the drive motor starts, it can drive the rotating gear to rotate, thereby causing the U-shaped seat to rotate around the heat-conducting sleeve. This allows the airflow from the cooling fan to be evenly distributed around the heat-conducting sleeve, improving heat dissipation efficiency. At the same time, it can prevent nozzle head deformation caused by local overheating. The rotating U-shaped seat can form a protective layer on the outside of the heat-conducting sleeve, forming a double layer of protection with the heat-conducting sleeve to prevent dust and foreign objects from entering. In addition, the U-shaped structure can concentrate the airflow and prevent airflow from overflowing and being wasted. Attached Figure Description

The nozzle head 10 and the connecting pipe 2 are connected. One end of the connecting pipe 2 is welded to the rear end of the nozzle head 10. The other end of the connecting pipe 2 is provided with an external threaded interface, which can be sealed to the feeding pipeline. The connection is made of a high-pressure resistant sealing gasket to ensure no leakage when the working pressure is 10-15MPa.

[0022] A heat-conducting sleeve 3 is fixed to the outside of the nozzle head 10. The heat-conducting sleeve 3 is made of copper, and multiple heat dissipation grooves 11 are opened on the outside of the heat-conducting sleeve 3, which penetrate the inside of the heat-conducting sleeve 3. This allows the heat generated by the nozzle head 10 during operation to be quickly transferred to the surface of the heat-conducting sleeve 3 through the heat dissipation grooves 11.

[0023] A support shell 1 is provided on the outside of the connecting pipe 2. A U-shaped seat 5 is rotatably connected to the side of the support shell 1 near the nozzle head 10. A heat-conducting sleeve 3 is provided inside the U-shaped opening of the U-shaped seat 5. A cooling fan 6 is fixed on the side of the U-shaped seat 5 away from the nozzle head 10. A ventilation opening is provided inside the U-shaped opening. The ventilation opening is connected to the air outlet of the cooling fan 6.

When the drive motor 9 starts, it can drive the rotating gear 4 to rotate through the drive gear 8, thereby causing the U-shaped seat 5 to rotate around the heat-conducting sleeve 3. This allows the airflow from the cooling fan 6 to be evenly blown around the heat-conducting sleeve 3, improving the heat dissipation efficiency. At the same time, it can prevent the nozzle head from deforming due to local overheating. The rotating U-shaped seat 5 can form a protective layer on the outside of the heat-conducting sleeve 3 to prevent dust and foreign objects from entering. At the same time, the U-shaped structure can concentrate the airflow and prevent the airflow from overflowing and being wasted.
