Description

Technical Field

[0001] The utility model relates to the technical field of zirconium-hafnium centrifugal separation, and more specifically, to a centrifugal extraction separator for separating zirconium and hafnium. Background Art

[0002] Zirconium and hafnium are the names of chemical elements, located at positions 40 and 72 in the periodic table respectively. Zirconium is one of the more common elements in the earth's crust and mainly exists in minerals such as zircon. Zircon is commonly used in fields such as manufacturing ceramics, alloys, and catalysts. Hafnium is also an element in the earth's crust and often exists together with zircon. It is mainly used as a structural material in nuclear reactors.

[0003] Separating zircon and hafnium usually requires the use of different chemical methods, such as centrifugal separation. A centrifugal extraction separator is a device used to separate components in a mixture. It can separate according to the density difference of substances. When separating zircon and hafnium, the method of heavy liquid separation can be used to separate them according to their density differences in a centrifuge. Through the centrifugal extraction separator, zircon and hafnium can be separated to different positions during the high-speed rotation of the centrifuge, thereby achieving their effective separation.

[0004] The existing centrifugal extraction separator for separating zirconium and hafnium usually uses an electric motor to drive the drum to rotate at a high speed. The light and heavy phase solutions enter the interior of the housing through the light phase inlet and the heavy phase inlet respectively according to a certain ratio. Then, the rotation of the electric motor drives the drum to rotate at a high speed, and the solution is separated by means of centrifugal force. However, when in use, the solution usually needs to be mixed. The existing extraction method only simply allows the heavy phase solution and the light phase solution to naturally mix, and the mixing efficiency and mixing effect are not ideal. If zircon and hafnium in the sample are not fully mixed and have poor dispersion, it may cause zircon and hafnium in the sample not to fully contact, thereby reducing the separation efficiency. Moreover, there will be local high-concentration and low-concentration regions, which will cause the separated substances to be unevenly distributed during the centrifugation process, extremely affecting the accuracy of separation;

[0005] And when cleaning the centrifugal extraction separator, regular cleaning is often required. The existing cleaning method usually requires the overall disassembly of the separator to clean the internal drum, heavy phase collection chamber, and light phase collection chamber, which undoubtedly reduces the cleaning efficiency of the personnel and is very cumbersome, causing many inconveniences to the actual use.

[0006] In view of this, we propose a centrifugal extraction separator for separating zirconium and hafnium. Content of the Utility Model

[0007] 1. Technical Problems to be Solved

[0008] The purpose of the present utility model is to provide a centrifugal extraction separator for separating zirconium and hafnium, so as to solve the problems of poor mixing uniformity and inconvenient cleaning mentioned in the above background technology.

[0009] 2. Technical solution

A mixing chamber, a sandwich chamber, a heavy-phase collection chamber and a light-phase collection chamber are arranged inside the housing. An ultrasonic generator and a controller are arranged on the front outer wall of the housing. An ultrasonic vibration rod I and a motor are arranged on the top of the fixed table. The output end of the motor is connected to a rotating drum.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present utility model are as follows: When extraction and separation are required, the motor can be used to drive the rotating drum to rotate at a high speed. The light and heavy phase solutions enter the mixing chamber from the light-phase inlet and the heavy-phase inlet respectively according to a certain ratio. Then, while the rotating drum rotates at a high speed, the mixing rod I and the mixing rod II are driven to mix the light and heavy phase solutions. During this mixing process, the ultrasonic vibration rod II can be used to cooperate with the mixing rod I and the mixing rod II to further mix the light and heavy phase solutions, thereby enabling zirconium and hafnium to fully contact and improve the separation efficiency, and making the light and heavy phase solutions more evenly distributed, improving the separation accuracy;

[0019] When it is necessary to clean the centrifugal extractor, cleaning water can enter the mixing chamber through the light-phase inlet and the heavy-phase inlet. Rotate the drum in the same way. During the rotation, use ultrasonic vibration rod 1 and ultrasonic vibration rod 2 to perform ultrasonic vibration on the cleaning water, so that the shear force generated by the rupture of tiny bubbles is used to clean the inner walls of the drum, the mixing chamber, the heavy-phase collection chamber, and the light-phase collection chamber, effectively improving the cleaning efficiency and reducing the labor burden that requires personnel to disassemble for cleaning.

The above all belong to the prior art.

[0032] Specifically, a plurality of first ultrasonic vibrators 290 extend through the light-phase collection chamber 270, the interlayer chamber 240, and the heavy-phase collection chamber 250 into the interior of the mixing chamber 230.

[0041] Working principle: When extraction and separation are required, the motor 300 can be used to drive the drum 310 to rotate at a high speed. The light and heavy phase solutions enter the mixing chamber 230 from the light phase inlet 210 and the heavy phase inlet 220 respectively according to a certain ratio. Then, while the drum 310 rotates at a high speed, the mixing rod one 350 and the mixing rod two 360 are driven to mix the light and heavy phase solutions. During this mixing process, the ultrasonic vibration rod two 340 can be used in cooperation with the mixing rod one 350 and the mixing rod two 360 to further mix the light and heavy phase solutions, so as to make zirconium and hafnium fully contact to improve the separation efficiency, and make the light and heavy phase solutions more evenly distributed to improve the separation accuracy. When the centrifugal extractor needs to be cleaned, the cleaning water can enter the mixing chamber through the light phase inlet 210 and the heavy phase inlet 220, and the drum 310 is rotated in the same way. During the rotation process, the ultrasonic vibration rod one 290 and the ultrasonic vibration rod two 340 are used to perform ultrasonic vibration on the cleaning water, so that the shearing force generated by the rupture of the micro-bubbles is used to clean the inner walls of the drum 310, the mixing chamber 230, the heavy phase collection chamber 250 and the light phase collection chamber 270, effectively improving the cleaning efficiency and reducing the labor burden that requires personnel to disassemble for cleaning.
