Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, in particular to an ultrasonic vibration screen. Background Art

[0002] Ultrasonic vibrating screen superimposes a high-frequency and low-amplitude ultrasonic vibration wave on the screen. The ultra-fine powder is subjected to huge ultrasonic acceleration, so that the material on the screen surface always remains in suspension, thereby suppressing factors such as adhesion, friction, flattening, wedging and other blocking factors, thereby solving the screening problems such as strong adsorption, easy agglomeration, high static electricity, high fineness, high density, and light specific gravity, making the screening of ultra-fine powder no longer a difficult task. It is especially suitable for users of high-quality and fine powders, so it is more commonly used in starch, protein, and fiber related processing.

[0003] Publication No. CN211134604U discloses an ultrasonic vibrating screen, which relates to the technical field of mechanical equipment. The ultrasonic vibrating screen includes a screen and a blowing mechanism, wherein the air jet of the blowing mechanism faces the screen. When in use, the material is continuously conveyed to the screen. Due to the uneven output of the material during the conveying process, the screen cannot pass the material in time, and slowly accumulates. At this time, according to the accumulation of the material, the blowing mechanism is started. Since the air jet of the blowing mechanism faces the screen, the material accumulated on the screen will be blown up by the gas ejected from the air jet. Subsequently, the material falls to different positions of the screen by its own gravity and passes through the screen again, thereby removing the accumulated material, increasing the material processing capacity, reducing the load of the screen, preventing damage to the screen, improving production efficiency, and reducing production costs. However, the patent still has the following problems in actual use:

[0004] The ultrasonic vibrating screen reduces the accumulation of materials on the screen by providing a blower. However, since the ultrafine powder in the ultrasonic vibrating screen is blown during screening, dust is easily generated when the ultrafine powder is discharged from the discharge port. Therefore, the ultrasonic vibrating screen is not convenient to use. Moreover, when the ultrasonic vibrating screen is used, the screen is easily blocked when screening a small number of materials with poor drying effect, thereby affecting the screening efficiency and service life of the screen, resulting in the ultrasonic vibrating screen being not very practical.

[0005] An ultrasonic vibrating screen is proposed to solve the above problems. Utility Model Content
