Ultrasonic vibration screen and method for filtering and screening powder by using same

Abstract

The invention relates to an ultrasonic vibration screen. The ultrasonic vibration screen comprises a bracket, a screen and an ultrasonic vibration head, wherein the screen is arranged on the bracket; the ultrasonic vibration head is arranged on the outer side of the bracket; the ultrasonic vibration head is provided with a vibration-transmitting shaft; a shaft hole is formed on the bracket; the vibration-transmitting shaft is inserted into the shaft hole from the outer side of the bracket and the end part of the vibration-transmitting shaft passes through the shaft hole; the end part of the vibration-transmitting shaft is connected with a vibration ring; and the vibration ring is close to the surface of the screen. A method for filtering and screening powder by using the ultrasonic vibration screen is characterized in that: the ultrasonic vibration head separated from the screen transmits vibration generated by the ultrasonic vibration head to the vibration ring through the vibration-transmitting shaft; and the vibration ring acts on the screen, so that the screen is vibrated up and down, large-particle powder is isolated by the screen, small-particle powder penetrates the screen, and the powder can be filtered and screened. By the ultrasonic vibration screen and the method for filtering and screening the powder by using the same, working efficiency is high; the screen is easy to clean and is difficult to break through vibration; and service life is long.

Description

Technical field: [0001] The invention relates to an ultrasonic vibrating screen and a method for filtering and screening powder. Background technique: [0002] The existing ultrasonic vibrating screen generally includes a support 01, a screen 02 with a mesh on the support 01, and an ultrasonic vibrating head 03 located at the center of the screen 02. The ultrasonic vibrating head 03 is provided with a power supply Connect the wire 04 as shown in picture 1. The ultrasonic vibrating screen has the following defects when filtering and screening powder: 1. Because the ultrasonic vibrating head and the electric wires connected to it are exposed above the screen, so when filtering and screening powder, the ultrasonic vibrating head and the electric wires connected to it will be powdered Covering, not easy to clean; 2. The ultrasonic vibrating head will heat up during the working process, resulting in solidification of the powder and low work efficiency; 3. The ultrasonic vibratin...
