[0002] An alloy is a substance with metallic properties that is synthesized by mixing two or more metals or non-metals through melting, cooling and solidification. Zirconium-hafnium alloy is a solid solution of zirconium, hafnium or other metals. Both zirconium and hafnium have good corrosion resistance. The main use of zirconium-hafnium alloy is in the field of nuclear technology, such as fuel rods in nuclear reactors.

The extraction device for producing zirconium-hafnium alloy according to claim 8, characterized in that: The outer wall of the rack (1203) is fixedly connected to a support plate 1 (1212), the outer wall of the support plate 1 (1212) is fixedly connected to a spring (1213), one end of the spring (1213) away from the support plate 1 (1212) is fixedly connected to a support plate 2 (1214), and the support plate 2 (1214) is fixedly connected to the top surface of the base (1).

10. An extraction method for producing zirconium-hafnium alloy, using the extraction device for producing zirconium-hafnium alloy as claimed in claim 9, characterized in that: The steps include: Step 1: adding extractant into the extractant cylinder (7) through the liquid inlet pipe (813), driving the second drive motor (801), and as the liquid level in the extractant cylinder (7) changes, the liquid outlet pipe (811) and the liquid level sensor (809) rise with the liquid level, so as to avoid splashing when adding the extractant and affecting the metering accuracy; Step 2: When the pointer (805) points to the required scale of the scale bar (806), the second drive motor (801) is turned off, and the extraction agent is continued to be added until the liquid level sensor (809) contacts the liquid surface, thereby achieving quantitative addition of the extraction agent; Step 3: Continue to drive the second drive motor (801) to move the liquid level sensor (809) and the liquid outlet pipe (811) to the top of the extractant cylinder (7), drive the first drive motor (501) to transfer the extractant cylinder (7) containing the extractant to the top of the extraction cylinder (11), control the control valve (10) to guide the extractant in the extractant cylinder (7) into the extraction cylinder (11), and at the same time, move another extractant cylinder (7) to the bottom of the liquid level sensor (809), and repeat the above operation to continue to add different types of extractants; Step 4: driving the driving motor 3 (1201) to make the extraction cylinder (11) reciprocate and shake in the horizontal direction, so that the extractant and the zirconium-hafnium alloy liquid are fully mixed to achieve extraction.
