Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical screening technology, specifically to an ultrasonic linear vibration screening device for pharmaceutical screening. Background Technology
[0002] An ultrasonic vibrating screen is a device that uses an ultrasonic transducer to cause the screen to vibrate, creating a high-frequency, low-amplitude ultrasonic wave on the screen surface. When ultrafine powders approach the screen surface, they receive ultrasonic acceleration, increasing the dispersion of the material as it passes through the screen. This keeps the material suspended on the screen surface. Particles larger than the screen mesh are screened to the discharge port, while particles smaller than the mesh fall through the mesh. It is particularly suitable for screening ultrafine powders and can also be used for pharmaceutical screening. However, existing ultrasonic linear vibrating screens do not provide good screening accuracy and are prone to secondary contamination and damage to the material due to the use of cleaning nets. Furthermore, existing ultrasonic linear vibrating screens generate significant noise during operation, which can cause discomfort.
[0003] To address the aforementioned issues, an ultrasonic linear vibration screening device for pharmaceutical screening is proposed. Utility Model Content
