Description

Technical Field

[0001] The utility model relates to the preparation of metal powders, and specifically refers to an ultrasonic device for preparing high-melting-point metal powders. Background Art

[0002] The ultrasonic metal powder preparation technology is a process that uses ultrasonic vibration to vibrate the metal melt and atomize the metal melt into powders. Currently, the ultrasonic metal powder preparation process is mainly used for low-melting-point metals and alloys such as tin alloys with a melting point below 400 degrees Celsius. However, for metals with a melting point above 400 degrees Celsius, there is a lack of feasible process solutions. In traditional solutions, a plasma flame is used to melt the wire and then ultrasonic vibration is used to powder the melt. However, the temperature control accuracy of the flame is poor, and the combustion area is large. A large combustion area is likely to heat the tool head, resulting in the temperature rise of the tool head. Once the tool head temperature rises too high, it will affect the normal use of the ultrasonic device. At the same time, the plasma flame occupies a large volume and consumes a large amount of power. Therefore, an ultrasonic device for preparing high-melting-point metal powders is proposed. Content of the Utility Model

[0014] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture as shown in the accompanying drawings. If this specific posture changes, then the directional indication will also change accordingly.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0016] Refer to Figure 1-2As shown in the figure, an ultrasonic device for preparing high-melting-point metal powder includes an atomization chamber 1; it is characterized in that it further includes an ultrasonic device 2 installed on the atomization chamber 1, an ultrasonic tool head 21 installed on the ultrasonic device 2 and located inside the atomization chamber 1, a laser 3 installed on the atomization chamber 1 corresponding to the position of the ultrasonic tool head 21, and a wire feeder 4 connected to the atomization chamber 1 with one end located inside the atomization chamber 1. The port of the wire feeder 4 at the end inside the atomization chamber 1 is located at the ultrasonic tool head 21;

[0017] By using laser as the heat source for heating the metal wire, the metal wire can be quickly melted through laser focusing, improving the melting efficiency of the metal wire, having better safety and being able to prepare metal powder with a melting point above 400 degrees. And by melting the metal wire in the way of laser focusing, the focusing method will not cause the temperature rise of the ultrasonic tool head 21, will not affect the service life of the ultrasonic tool head 21, and the melting rate of the metal wire can be well controlled by using the laser melting method, and the atomization process can be terminated at any time;

[0018] The laser 3 can be placed inside the atomization chamber 1 or installed outside the atomization chamber 1. When installed outside the atomization chamber 1, only the atomization chamber 1 or the position corresponding to the laser 3 needs to be set as transparent. Installing the laser 3 outside the atomization chamber 1 can also prevent the prepared powder from adhering to the laser 3, and the position of the focus point can be adjusted in real time during the operation of the equipment.

[0019] In one embodiment, it further includes a primary cyclone separator 5 connected to the atomization chamber 1 through a pipeline, a secondary cyclone separator 6 connected to the primary cyclone separator 5 through a pipeline, and a vortex blower 7 connected to the secondary cyclone separator 6 through a pipeline.

[0020] A primary collection barrel 51 is installed below the primary cyclone separator 5, and a secondary collection barrel 61 is installed below the secondary cyclone separator 6;

[0021] The metal powder made by ultrasonic first enters the primary cyclone separator 5 for preliminary separation. Part of the coarse powder falls into the primary collection barrel 51 at the bottom, and the fine powder then enters the secondary cyclone separator 6 through the pipeline and is filtered by the secondary cyclone separator 6. The fine powder falls into the secondary collection barrel 61 to complete the classified storage of the metal powder. Then the filtered gas enters the vortex blower 7 through the pipeline, and the vortex blower 7 blows the gas back into the atomization chamber 1 through the air outlet channel.

[0022] In one embodiment, a pressure adjustment device 9 is further installed on the secondary cyclone separator 6 to ensure the stable operation of the cyclone separator through the pressure adjustment device 9.

[0023] When the utility model is in use: the metal wire is sent to the ultrasonic tool head 21 of the ultrasonic device 2 through the wire feeder 4, and then the metal wire at the ultrasonic tool head 21 is heated and melted by the laser 3. Then, the ultrasonic tool head 21 vibrates and atomizes the melted metal melt. The atomized metal powder drifts in the atomization chamber 1. Through the suction of the vortex fan 7, the metal powder in the atomization chamber 1 enters the primary cyclone separator 5 through the pipeline. After being separated by the primary cyclone separator 5, part of the coarse powder will fall into the primary collection barrel 51, and the finer powder will enter the secondary cyclone separator 6 through the pipeline. After being filtered by the secondary cyclone separator 6, the fine powder will fall into the secondary collection barrel 61. Then, the clean gas will enter the vortex fan 7 through the pipeline and return to the atomization chamber 1 through the air outlet pipeline 8.

[0024] The protection scope of the utility model is not limited to the above embodiments and their transformations. Routine modifications and replacements made by those skilled in the art based on the content of this embodiment all fall within the protection scope of the utility model.
