SU148709A1 - Vibratory hopper - Google Patents

Description

BASIC Auth. St. No. 137381 describes a vibratory hopper, the vibrating bowl of which is made in the form of a vibrating cylinder with a screw tray fixed on its inner surface and a fixed or vibrating bottom from a separate drive.

The proposed vibratory bunker differs from the known one in that the vibrator (for example, electromagnetic) of the thickener circle and the cylinder vibrator are arranged in such a way that the base at each time point is exposed to two reactive moments of forces that are directed in opposite directions, resulting in the base's reactive oscillations mutually quench. As a consequence, the required base mass can be reduced.

The drawing shows the layout of the vibrators (electromagnets) in the vibratory hopper.

On the base / vibratory hopper are located vibrators 2 cylinders and vibrators 5 round the bottom of the bowl. The arrows indicate the direction of the thrust generated by the vibrators.

Subject invention

Vibration bun on aut. St. No. 137381, characterized in that, in order to reduce the required base mass by reducing its reactive vibrations, the inner circle of the bottom of the thickener is driven by, for example, an electromagnetic vibrator, the direction of the disturbing vibrations of which is opposite to the direction of the disturbing vibrations of the cylinder vibrator.
