Description

Technical Field

[0001] The utility model belongs to the field of ultrasonic magnetic stirring, in particular to an ultrasonic magnetic stirring device. Background Art

[0002] Commonly used stirring devices include magnetic stirrers, ultrasonic dispersers, etc. The advantages of magnetic stirrers are that the container is easy to seal, easy to use, easy to clean, and highly efficient. It has become a standard in many fields. The disadvantage is that the power is limited and it is only suitable for rough dispersion and dissolution of low-viscosity liquids, and cannot achieve ultrafine dispersion. The advantages of ultrasonic dispersers are high efficiency, high power density, and can achieve rapid emulsification or dispersion. It is especially suitable for ultrafine dispersion processes, safe and easy to clean. The disadvantage is that the lack of a stirring paddle makes it difficult for the material to form macroscopic convection, and the effect is greatly affected by the overall uniformity and viscosity of the material.

[0003] In addition, the Chinese patent with the announcement number CN205412858U discloses a magnetic stirrer with ultrasonic waves, including: an ultrasonic tank, which is a tank structure with an opening on the upper part; an ultrasonic part, which is arranged on the outer wall of the ultrasonic tank to crush the solute; a magnetic stirring device, which includes a magnet, a motor and a rotor, wherein the magnet is arranged on the outer wall of the bottom of the ultrasonic tank and is connected to the motor, the motor drives the magnet to move, and the rotor is arranged in the ultrasonic tank and moves with the magnet to stir the solute. The defects are as follows: 1. The liquid must be sufficient and the liquid level must be higher than the transducer, otherwise the transducer is prone to burnout and damage; 2. The ultrasonic transducer must be fixed on a plane, that is, there must be a flat part on the side of the container, and the magnetic stirrer generally requires the container to be round, so that the material can form a good flow and avoid turbulent dead corners, which are contradictory; 3. The energy output direction of the ultrasonic transducer is horizontal, which cannot take into account all positions, which is not conducive to the ultrasonic dispersion effect.

[0004] In summary, designing a new stirring device becomes the subject faced by the present utility model. Utility Model Content

[0022] In this embodiment: the main unit 2 includes a main body 201, and a limiting platform 202 is arranged on the upper surface of the main body 201. The limiting platform is used to hold the stirring container 4. The limiting platform can be a table with a circular hole. An ultrasonic transducer 203 is arranged below the bottom surface of the stirring container 4. The ultrasonic transducer 203 is a sheet structure. The stirring container 4 is a barrel flat bottom structure for holding a magnetic rod and raw materials. The ultrasonic transducer 203 generates ultrasound to dissolve the raw materials.
