Triple-frequency ultrasonic extraction device and using method thereof

The present invention discloses a three-frequency ultrasonic extraction apparatus includes an ultrasonic extraction tank, ultrasonic generator, a condenser, a cooler and a water separator, ultrasonic extraction upper tank is provided with mist eliminators, mist eliminators are sequentially and the condenser via conduit , a cooler and a water separator connected to the bottom of the oil-water separator is connected to the tank via conduit ultrasonic extraction, ultrasonic extraction intermediate tank provided with six-sided cartridge oscillator, piercing wire from a stainless steel tube connected to the ultrasonic generator, ultrasonic extraction tank of circular configuration, is attached to an upper feed opening, a lower opening for the slag; side portion is provided with a solenoid valve and the circulation pump. The present invention also discloses a method of using the three-frequency ultrasonic extraction device, the extraction device so that the multi-frequency ultrasonic extraction technique applied to industrial production can be achieved. Compared with the single-frequency ultrasonic extraction, extraction of good uniformity, the extraction rate, lower temperature requirements, the extraction time is shortened, further reducing the required solvent.
