[0002] High entropy alloy is an alloy formed by five or more equal or approximately equal amounts of metals, and has excellent mechanical properties, corrosion resistance, high temperature stability, etc. The Chinese invention patent with patent number CN221182349U provides a mixing device for the preparation of high entropy alloys, which uses a staggered spiral distribution of feed pipes between the top and bottom of the cylinder, effectively ensuring the cyclonic high-speed mixing of the alloy metal material when it falls from the second feed port, and significantly improving the mixing uniformity of the alloy metal material. However, when the device mixes the materials, it can only mix them layer by layer. When too much material is accumulated at the bottom of the conical collection barrel, it will cause difficulty in discharging the feed pipe, and it is difficult to stir and mix the accumulated materials, so that the uniformity cannot be further improved, highlighting the shortcomings of the prior art.

When the material gradually blocks the penetration point at the bottom of the lower barrel 9, the lower barrel 9 and the main stirring plate 10 can be moved downward by controlling the electric push rod 7 to extend the push rod. At this time, the mixing barrel 1 drags the material to move, so that the material can be stirred and mixed to make the mixture more uniform.
