Description

Technical Field

[0001] The utility model relates to the technical field of spherical alloy powder preparation, and more specifically, to a device for preparing spherical alloy powder. Background Art

[0002] Metal powder is formed by partial or complete alloying of two or more components. Alloy powders are mainly classified into iron alloy powder, copper alloy powder, nickel alloy powder, cobalt alloy powder, aluminum alloy powder, titanium alloy powder and precious metal alloy powder according to their components. Atomization powder making method is a powder making method that uses fast-moving fluid (atomizing medium) to impact or otherwise break metal or alloy liquid into fine droplets, and then condenses them into solid powder.

[0003] In copper indium gallium alloy, due to the different melting points and the surface energy between the materials, when they are directly atomized and collected through an atomizer, the particles gather together and produce mutual forces, which easily lead to mutual attraction between the particles, thereby causing agglomeration effect, resulting in small satellite balls attached to the surface of the alloy powder particles. In view of this, it is particularly important to provide a preparation device that can increase the flow between particles and reduce the particle agglomeration effect. In view of this, we propose a preparation device for spherical alloy powder. Utility Model Content

[0024] like Figures 1 to 5 As shown, the utility model relates to a spherical alloy powder preparation device, comprising an atomizer 1, characterized in that a mist exhaust port is arranged at the lower end of the atomizer 1, and a mist exhaust component 2 is arranged in the mist exhaust port;

[0025] The demisting assembly 2 includes a demisting pipe 201, the surface of the demisting pipe 201 is rotatably connected to the lower end of the atomizer 1, a plurality of through holes are evenly spaced on the surface of the demisting pipe 201, a cavity is provided inside the demisting pipe 201, the demisting pipe 201 is connected to the demisting port of the atomizer 1 through the cavity, a fan blade 202 is fixedly connected to the cavity through a connecting rod, the demisting pipe 201 includes a connecting portion 2011 and a protruding portion 2012, the connecting portion 2011 is in a hemispherical shape, the protruding portions 2012 are evenly arranged on the spherical surface of the connecting portion 2011, the protruding portions 2012 are in a conical shape that is contracted and protruded outward from the connecting portion 2011, the interior of the protruding portion 2012 is connected to the through hole, a processing chamber 3 is provided at the lower end of the atomizer 1, and the lower end of the processing chamber 3 is threadedly connected to the processing chamber 3. It is connected to a collecting tank 6. By setting the fan blades 202, when the atomizer 1 sprays the atomized particles, a force can be generated on the surface of the fan blades 202, so that the fan blades 202 can drive the mist exhaust component 2 to rotate, so that the atomized particles can be evenly sprayed in the treatment chamber 3 through the rotating mist exhaust pipe 201. At the same time, by setting the connecting part 2011 in the mist exhaust component 2, its spherical semi-section can be utilized to make the atomized particles evenly and dispersedly sprayed on the surface of the treatment chamber 3, thereby improving the comprehensiveness of the spraying angle of the atomizer 1. Through the raised part 2012, its conical shape can be utilized to make the shape of the atomized particles more uniform and smooth after formation and spraying, thereby reducing the situation where the atomized particles stick to each other when spraying.

[0026] In an embodiment of the utility model, an annular tube 4 is arranged on the inner wall of the processing chamber 3, and a plurality of nozzles 401 are evenly distributed on the surface of the annular tube 4. An air pipe 402 is fixedly connected to one end of the annular tube 4, and the end of the air pipe 402 is connected to a spray tank filled with inert gas. By setting the air pipe 402, the air pipe 402 can be used to transport the inert gas, and the inert gas can be used to spray the surface of the atomized particles, thereby reducing the flow rate of the atomized particles and reducing the collision between the particles. At the same time, by setting the annular tube 4, its annular surface can be used to enable the inert gas to be fully sprayed inside the processing chamber 3 and in all-round contact with the particles, which can improve the use effect of the inert gas and reduce the generation of satellite balls.

[0027] In an embodiment of the utility model, a valve channel 5 is fixedly arranged on the inner wall of the processing chamber 3, and the valve channel 5 is arranged at the lower end of the annular tube 4. By setting the valve channel 5, the inclined surface of the valve channel 5 can be used to guide the travel direction of the atomized particles so that they can flow into the collection tank 6, and the collected atomized particles are limited by the channel characteristics of being wide at the top and narrow at the bottom, so that the opening for the atomized particles at the bottom to flow upward is narrowed, which can effectively collect the atomized particles and prevent the atomized particles from flowing back and rising.

[0028] Working principle: This embodiment provides a device for preparing spherical alloy powder. When in use, after the particles are atomized by the atomizer 1, the atomized particles are first discharged into the cavity through the mist exhaust component 2, and the flow rate generates an impact force on the fan blade 202, so that the fan blade 202 drives the mist exhaust component 2 to rotate. Then, during the rotation process, the atomized particles first contact the inner wall of the through hole, and then are rotated and sprayed into the processing chamber 3 through the protrusion 2012. Then, the inert gas is transported to the annular tube 4 through the air pipe 402 and sprayed into the processing chamber 3 to contact the atomized particles, so as to passivate the flow rate of the atomized particles and reduce the adhesion between the particles. Then, the atomized particles are guided at the wide mouth of the valve channel 5 to divert the atomized particles, so that the atomized particles are collected in the collection tank 6. When the atomized particles need to be taken, the collection tank 6 can be rotated clockwise to drive the collection tank 6 to separate from the lower end of the processing chamber 3.
