an ultrasonic airflow sieve comprises a machine body, a blanking disc, a screen, an ultrasonic mechanism, a negative pressure mechanism and a material recovery mechanism, wherein the upper end of the machine body is open, and a cavity is formed in the machine body; the blowing mechanism comprises a hollow shaft, a blowing blade and a blowing groove, wherein the bottom of the hollow shaft is communicated with the cavity and is connected with the blanking disc through a bearing, the blowing blade is arranged on the upper surface of the blanking disc, one end of the blowing blade is connected to the top of the hollow shaft, and the blowing groove is communicated with the hollow shaft and has an inclination angle.

The blowing blades are arranged along the radius direction of the blanking disc, and the blowing grooves are formed along the length direction of the blowing blades.

The negative pressure mechanism further comprises a pipeline filter, and the pipeline filter is arranged outside the machine body and connected to a pipeline between the vacuum fan and the separator.

And a material receiving bottle is arranged at the bottom of the discharge hole.

The separator is a conical cyclone separator.

The ultrasonic airflow screen has the following advantages that:

1. the materials are screened by ultrasonic waves, negative pressure blanking is combined, and the materials can be screened rapidly and effectively.

2. Through the vacuum pumping of negative pressure mechanism, make the gas in the cavity upwards blow off from the mechanism of blowing, blow the material on the screen cloth and float, can effectively avoid the material to reunite, be favorable to the quick accurate screening of material.

3. The blowing blade adopts an inclined blowing groove, and when air flow passes through the blowing groove, a component force for driving the blade to rotate is generated, so that the blowing blade can be driven to rotate, the blowing is free of dead angles, and the screening effect can be better due to blowing and stirring air flow.

4. The negative pressure mechanism is arranged in the machine body and integrated with the screening instrument machine body into a whole structure.
