The plurality of MO source cylinders 3 are placed in the water bath 1 through a supporting assembly, and a first vibration assembly is detachably installed on both sides of the water bath 1, and a second vibration assembly is fixedly arranged inside the water bath 1;

[0021] The first vibration assembly includes two first end plates 4, which are symmetrically fixed on the top of both sides of the water bath 1. The first vibration assembly also includes two accommodating boxes 5, and the tops of the two accommodating boxes 5 are fixed with second end plates 6. The two second end plates 6 correspond to the two first end plates 4 one by one, respectively. The first end plates 4 and the corresponding second end plates 6 are fixedly connected by fixing bolts 7. Specifically, the user can control the disassembly and assembly between the first end plates 4 and the second end plates 6 by disassembling and assembling the fixing bolts 7, so that the accommodating box 5 and the water bath 1 can have a disassembly and assembly function. The accommodating box 5 can be used to store the MO source cylinder 3, and it should be noted that the inner diameter of the accommodating box 5 is larger than the diameter of the MO source cylinder 3 to ensure that the MO source cylinder 3 can shake in the accommodating box 5;

[0022] The inner wall of the container box 5 is fixed with a rubber lining 8, which can effectively protect the MO source cylinder 3, effectively prevent the MO source cylinder 3 from excessively colliding with the inner wall of the container box 5 during the knocking and vibration process, and reduce noise. A C-shaped connecting plate 9 is fixed to one end of the container box 5 away from the water bath 1, and an electric push rod 10 is transversely fixed to the end of the C-shaped connecting plate 9. It should be noted that the electric push rod is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. A hammer head 11 is fixed to the output end of the electric push rod 10. 10 are electrically connected to the control panel 2, a first through hole 12 is provided on one side of the receiving box 5 away from the water bath 1, a second through hole 13 is provided on one side of the rubber lining 8 away from the water bath 1, and the hammer head 11 can pass through the first through hole 12 and the second through hole 13 in sequence. Specifically, when the electric push rod 10 is running, it can drive the hammer head 11 to move back and forth laterally, so that the hammer head 11 can pass through the first through hole 12 and the second through hole 13 in sequence, thereby automatically knocking and vibrating the MO source cylinder 3 placed in the receiving box 5, saving time and effort;

[0023] The support assembly includes several groups of support frames 14, each group of support frames 14 is fixed with a limiting ring 15 at the top, and each group of support frames 14 is fixed with an annular bottom plate 16 in the middle. The bottom of the MO source cylinder 3 passes through the limiting ring 15, and the bottom of the MO source cylinder 3 is placed on the top of the annular bottom plate 16. It should be noted that the inner ring diameter of the limiting ring 15 is larger than the diameter of the MO source cylinder 3 to ensure that the MO source cylinder 3 can shake in the water bath 1. Specifically, under the action of the support frame 14, the limiting ring 15 and the annular bottom plate 16, the required MO source cylinder 3 is placed in the water bath 1 without contacting the inner wall of the water bath 1.

The plurality of first ultrasonic oscillators 17 and the second ultrasonic oscillators 18 are electrically connected to the control panel 2. Specifically, under the action of the plurality of first ultrasonic oscillators 17 and the second ultrasonic oscillators 18, the microbubbles generated by the water in the water bath 1 can maintain the vibration source bottle in different directions under the action of sound waves, thereby realizing the function of ultrasonic oscillation, so that the MO source cylinder 3 is continuously in an ultrasonic oscillation state during the distillation process, effectively avoiding the agglomeration of the Mg source after long-term storage, which is beneficial to the distillation and purification effect.

[0025] The use process of the utility model is as follows: the user can first store the MO source cylinder 3 required for the solid crystal distillation purification of the solid MO source into the storage box 5, and then turn on the electric push rod 10 through the control panel 2. When the electric push rod 10 is running, it can drive the hammer head 11 to move back and forth horizontally, so that the hammer head 11 can pass through the first through hole 12 and the second through hole 13 in sequence, so as to automatically knock and vibrate the MO source cylinder 3 placed in the storage box 5, saving time and labor. Then the user puts the MO source cylinder 3 after knocking and vibration into the annular bottom film 16 on the inner side of the support frame 14 in the water bath 1, so that the required MO source cylinder 3 is placed in the water bath 1 without contacting the inner wall of the water bath 1, and then the solid crystals of the solid MO source are distilled and purified. During the distillation process, the user can turn on the first ultrasonic oscillators 17 and the second ultrasonic oscillators 18 through the control panel 2. Under the action of the first ultrasonic oscillators 17 and the second ultrasonic oscillators 18, the microbubbles generated by the water in the water bath 1 can maintain the vibration source bottle in different directions under the action of sound waves, thereby realizing the function of ultrasonic oscillation, so that the MO source cylinder is continuously in an ultrasonic oscillation state during the distillation process, effectively avoiding the agglomeration of the Mg source after long-term storage, which is beneficial to the distillation and purification effect.
