Abstract
The present invention discloses a multi-dimensional vibration grinding cavity body. By adjusting amplitudes (power) and frequencies of the multi-dimensional ultrasonic vibration source, such that the multi-directional macroscopic flow is formed in the cavity body while keeping the vibration medium to have the original characteristics to improve the performance of grinding of slurry.
Claims9
A multi-dimensional vibration grinding cavity body, comprising:
- a cylindrical cavity body, configured to contain an abrasive slurry;
- at least four ultrasonic vibration sources, disposed uniformly around a sidewall of the cylindrical cavity body, wherein the plurality of ultrasonic vibration sources deliver shock waves toward an interior of the cylindrical cavity body, and directions of the plurality of shock waves, delivered by the plurality of ultrasonic vibration sources, form an angle with a direction of a tangent plane of the sidewall, on which the ultrasonic vibration sources are disposed, wherein the angle is 15°-45°, and the plurality of shock waves, delivered by the plurality of ultrasonic vibration sources, make a convolutional flow pattern of the abrasive slurry in the cylindrical cavity body;
- and
- a turntable disc, disposed inside a bottom of the cylindrical cavity body, wherein the turntable disc rotates in a direction cooperating with directions of the shock waves to enhance performance of the convolutional flow of the abrasive slurry in the cylindrical cavity body.
