Description
Technical field
The invention belongs to disperser field more particularly to a kind of non-contact high-frequency ultrasonic dispersers.
Background technique
Disperser avoids the formation of aggregate, precipitating for the little particle dispersion in dispersing liquid.Existing disperser type
More, the immediate prior art is ultrasonic dispersers, it is used to contain the container of liquid using one, and in bulk container interpolation
Enter a hollow bar, is provided with ultrasonic generator in hollow bar.Ultrasonic wave occurs for ultrasonic generator, and passes to appearance by hollow bar
In device, and then ultrasonic vibration is generated to the liquid in container, with the little particle in dispersing liquid, avoids the formation of aggregate, precipitating,
After completing dispersion, then that liquid poured out container is spare.
There are two the main disadvantages of this ultrasonic dispersers: one, be contact type structure, i.e., hollow bar can in container
Liquid contact, and hollow bar may be chemically reacted with liquid, thus can contaminated fluid, can not make so as to cause liquid
With.Two, after completing dispersion, then liquid is poured out to little particle after container is spare, and the liquid after dispersing stands a period of time and is held very much
Easily assemble again, forms aggregate, precipitating again, the meaning of dispersion is thus lost, because there is the liquid of aggregate, precipitating
It can not be available completely in some industries.Three, can not be within certain working range to the liquid insulating after dispersion, this is asked
Topic is unable to satisfy some workplaces.
