Electromagnetic stirring type ultrasonic water bath device

Abstract

The invention relates to an electromagnetic stirring type ultrasonic water bath device which comprises a water bath kettle, an ultrasonic transducer, a rectangular electromagnet, a temperature controller, an ultrasonic generation controller and an electromagnetic stirring controller, wherein the rectangular electromagnet is arranged on the water bath kettle; the temperature controller, the ultrasonic generation controller and the electromagnetic stirring controller are respectively used for controlling the water bath, ultrasound and the electromagnetic mixing; the rectangular electromagnet is arranged around a water bath slot in the water bath kettle, and is provided with two groups of coils; and each group of coils comprise two opposite coils which have the same current direction. According to the electromagnetic stirring type ultrasonic water bath device, changed direct current is generated in the electromagnetic stirring controller, so that an electromagnetic field with regular rotation is generated in the water bath slot defined by the rectangular electromagnet, and permanent magnet stirrers in a plurality of samples arranged at any positions of the water bath slot are driven to rotate; and therefore, the defect that only the single sample arranged in the center of an area is stirred by the electromagnetic stirring can be overcome, and the electromagnetic stirring efficiency is improved.

Description

technical field [0001] The invention belongs to an ultrasonic water bath device, in particular to an electromagnetic stirring ultrasonic water bath device capable of simultaneously performing electromagnetic stirring treatment on a plurality of samples. Background technique [0002] As an ultrasonic device, the ultrasonic water bath device has a wide range of uses in the laboratory. For example, ultrasonic cleaners, in addition to cleaning glassware and other experimental utensils in the laboratory, are often used in other experimental occasions that require ultrasonic treatment to investigate the impact of ultrasound on test materials and results. In some experiments, the test material often needs to be stirred continuously while being in an ultrasonic water bath. The stirrer and the traditional magnetic stirring device can only stir a single sample, which greatly limits the improvement of the processing efficiency of the test material by the ultrasonic water bath device. ...

AI Technical Summary

Problems solved by technology

Therefore, a magnetic stirring device can only drive a single permanent magnetic stirring bar to process a single sample, which affects the efficiency of stirring and processing the test material.
