A laboratory multi-chamber ultrasonic grinding mixer

Abstract

The invention proposes a multi-bin ultrasonic grinding mixer for a laboratory. The mixer comprises at least two sets of grinding balls for matched grinding, and a grinding mixing tank; the grinding balls include ball bodies and neck rods arranged at the upper ends of the ball bodies; sleeves are fixedly arranged at the upper parts of the neck rods; the neck rods below the sleeves are inserted in a bearing plate connected with a base; a driving motor is arranged at the upper end of the base; an output shaft of the driving motor is connected with a transmission machine piece through a transmission shaft; the transmission machine piece is connected with the top ends of the neck rods; the driving motor drives the grinding balls to rotationally grind in the grinding mixing tank; the bottom end of the base is connected with a frame through an air valve lifting table; a water tank for bearing the grinding mixing tank is fixedly arranged on the frame below the grinding mixing tank, and is connected with an ultrasonic emitter through a transducer; and ultrasonic waves are transferred into the grinding mixing tank to vibrate materials through a water medium. The mixer realizes fast and efficient grinding and mixing through grinding and ultrasonic vibration to improve the sample uniformity and speediness.

Description

technical field [0001] The invention relates to the field of grinding and mixing, in particular to a laboratory-used multi-compartment ultrasonic grinding and mixing machine. Background technique [0002] In the existing laboratory, the powder mixture samples (1-100g) are manually ground and mixed by traditional mortar grinding method. Depending on the material, shape and size of the material, the grinding time of a single sample is less than half an hour. to 1 hour; when grinding, it is necessary to use grinding balls of different materials and sizes, and during the grinding process, the material will stick to the wall of the grinding ball or the inner wall of the mortar and is not easy to fall off, resulting in uneven mixing, and Quantitative experiments cannot be carried out due to material loss; in order to ensure sufficient material circulation, it is necessary to scrape lightly with a medicine spoon several times, so the operation is time-consuming and labor-intensive....

AI Technical Summary

Problems solved by technology

At present, there is no grinding machine for grinding and mixing powder mixture samples of 1-100g

[0004] In addition, whether it is manual grinding with a mortar or most laboratory micro-grinders, only one sample can be ground at a time, and there are many inconveniences

Although individual laboratory micro-grinders can process 2-6 samples at the same time, in order to maintain balance, the weight of the samples is required to be equal, and it cannot handle samples with large differences in weight.
