Product Introduction
Ultrasonic test sieve is different from ordinary test sieve, which can carry out particle size inspection on extremely fine and difficult-to-screen material particles. It is a kind of screening equipment used in laboratories and scientific research rooms for particle size analysis of small amounts of materials. An ultrasonic system is added to the original test sieve to complete the screening of fine powder materials. It is widely used in laboratories in the pharmaceutical, metallurgical, chemical, mineral processing, and food industries.
Structure Composition
The
ordinary test sieve is composed of two parts: the test sieve frame and the test sieve host, while the ultrasonic test sieve is based on these two parts with an additional ultrasonic system. It is composed of three parts: the screen frame, the host and the ultrasonic system.
Working Principle
The ultrasonic system is connected to the screen frame through an external ultrasonic transducer, and the high-frequency electric oscillation generated by the ultrasonic vibration power supply is uniformly transmitted to the screen surface by the oscillator. The material on the screen is subjected to low-frequency three-dimensional vibration and superimposed on ultrasonic vibration, which can prevent the mesh from blocking the mesh and improve the screening output and quality.
Steps For Usage
1. Adjust the screening time according to the screening needs. There is a time relay on the host panel that can be accurate to the second, and the timing time can be adjusted within 0-99 minutes and 59 seconds.
2. The principle of the screen frame from top to bottom from coarse to fine to prevent the screen frame, up to 8 screen frames can be placed, and the material to be screened is placed on the top layer.
3. Put the sieve frame into the main machine and lock the nuts on the top and both sides. The specific method is: first loosen the vibrating machine and the four lock nuts on both sides, so that the two uprights on both sides can fall freely and fall on the standard test sieve that has been placed, and then lock the two sides The nuts are locked, and finally the two nuts on the top of the screen are locked. Note that the nuts on the top and sides must be tightened.
4. After placing the screen frame, it can be turned on and used. Press the green button on the main unit and turn on the ultrasonic system to set the screening time. The screening of materials can be automatically controlled. If you need to pause in the middle, you can also directly press the red button. End screening with one click.
