Abstract

An ultrasonic vibrating screen includes a bottom frame, at least two screen cylinders, and a vibrating mechanism. An elastic body is provided on the bottom frame; the screen cylinders are arranged in sequence from bottom to top, each screen cylinder is provided with a screen, and one of the screen cylinders is connected with the bottom frame through the elastic body. The vibrating mechanism includes a vibrating frame and at least two ultrasonic transducers, the screen cylinders are all fixed to the vibrating frame, the ultrasonic transducers are fixed to the vibrating frame, and the ultrasonic transducers drive the vibrating frame to vibrate. By fixing all the screen cylinders with the vibrating frame, the amplitudes and frequencies of all ultrasonic transducers which are originally unsynchronized are unified to be the same amplitude and the same frequency as much as possible.

First claim

The invention claimed is:

1. An ultrasonic vibrating screen, comprising:
a bottom frame, wherein an elastic body is provided on the bottom frame;
at least two screen cylinders, wherein the screen cylinders are arranged from bottom to top in sequence, each of the screen cylinders is provided with a screen, and one of the screen cylinders is connected to the bottom frame via the elastic body;
a vibrating mechanism, wherein the vibrating mechanism comprises a vibrating frame, at least two ultrasonic transducers, and a connecting piece; wherein the screen cylinders are all fixed to the vibrating frame, the ultrasonic transducers are fixed to the vibrating frame, and the ultrasonic transducers are configured to drive the vibrating frame to vibrate, wherein the vibrating frame comprises at least two vibrating rings and a plurality of brackets, the vibrating rings are in one-to-one correspondence with the screen cylinders; wherein each of the vibrating rings is sleeved on an outer side surface of the corresponding screen cylinder and is fixed to the corresponding screen cylinder, and the vibrating rings are fixed with each other by the bracket;
wherein each of the brackets extends from top to bottom, each of the brackets is fixed with at least one of the ultrasonic transducers, and the brackets are distributed at intervals around outer surfaces of the screen cylinders, wherein the connecting piece is an arc-shaped rod, and each two of the brackets are fixed with each other by the connecting piece; and
at least one positioning block, wherein the positioning block is slidably sleeved on the connecting piece, the positioning block is connected with one of the screen cylinders, the positioning block comprises a top block, a body and a telescopic block, wherein the connecting piece is sandwiched between the top block and the body; and wherein the telescopic block is located at a side of the body away from the top block, and the telescopic block abuts against the one of the screen cylinders; and the top block is provided with a threaded through hole, the body is provided with a penetration hole corresponding to the threaded through hole, and a clamping rod is arranged in the penetration hole; an adjusting screw is screwed in the threaded through hole, the adjusting screw abuts against one end of the clamping rod, and the other end of the clamping rod away from the adjusting screw abuts against the telescopic block.

2. The ultrasonic vibrating screen according to claim 1 , wherein the ultrasonic transducers are distributed at intervals around the outer surfaces of the screen cylinders and are arranged on the brackets.

3. The ultrasonic vibrating screen according to claim 1 , further comprising a counterweight block, wherein the counterweight block is connected with the vibrating frame or the connecting piece.

4. The ultrasonic vibrating screen according to claim 3 , wherein the counterweight block has an annular shape, and the counterweight block is slidably sleeved on the connecting piece; wherein a threaded hole is provided on a side surface of the counterweight block, a fixing screw is screwed into the threaded hole, and the fixing screw passes through the threaded hole and abuts against the connecting piece.
