Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, but limited the utility model never in any form, any change done based on the utility model training centre or improvement, all belong to protection domain of the present utility model.
As shown in Figure 1, the utility model comprises liquid outlet 1, lower cone 3, extractant input pipe 6, cylindrical shell 7, upper cover 13, Pressure gauge 9, thermometer 10 and material inlet 11, place of bottom centre in cylindrical shell 7 is provided with a jet pipe 16 straight up, the bottom of jet pipe 16 is connected with extractant input pipe 6, top is sealed by blind plate 14, extractant input pipe 6 is provided with high-pressure pump 5, the middle part of cylindrical shell 7 is also provided with the ultrasonic processing apparatus 15 be made up of supersonic generator and ultrasonic transducer, lower cone 3 is provided with the metal filter screen 19 of 2 ~ 3 layers with the junction of cylindrical shell 7, cylindrical shell 7 on the upside of metal filter screen 19 is provided with the dumping pit 17 of 1 ~ 2, described liquid outlet 1 is arranged on the bottom of lower cone 3, described material inlet 11 is arranged on upper cover 13, described extractant input pipe 6 is arranged on the bottom of cylindrical shell 7, described upper cover 13 is ellipsoidal head, butterfly end socket or flat cover.
The utility model in use, first in tank, raw material is added by material inlet 11, adopt force (forcing) pump 5 to input extractant by extractant input pipe 6 simultaneously, extractant is penetrated by jet pipe 16, described jet pipe 16 can be cylindrical or conical, extractant is under the effect of vibration of ultrasonic processing apparatus 15, with raw material mixed at high speed, the collision of input, put forward high molecular kinergety, make its extractive reaction more thorough, after extraction, open tapping valve 2, discharge extract, filter residue is then discharged from dumping pit 17.
Further, the downside of the inherent metal filter screen 19 of described lower cone 3 is also provided with three layer filtration plate 4, described filter 4 is processed with the filter bores of several inclination, the aperture of described metal filter screen 19 and filter 4 reduces from top to bottom successively, be because three layer filtration plate 4 can form unique eddy current air chamber on the one hand, be conducive to carrier gas, material effectively can be contacted with extractant, the further effect strengthening extraction is that filter effect is better on the other hand.
In order to ensure equipment safety, stable operation within the time of extractive reaction, described upper cover 13 is also provided with safety valve.
Further, described cylindrical shell 7 being provided with peep hole 8, is the material reaction situation for the ease of observing in cylindrical shell 7, and the foreign material in cleaning cylindrical shell 7.
Further, described upper cover 13 is also provided with extractant interpolation mouth 12 is conveniently add extractant and other the raw material needed for extraction.
Discharge plate 18 is movably installed with in described dumping pit 17, because if dumping pit 17 does not arrange baffle plate 18, charge and discharge 17 hole is opened once needs, a large amount of material slags likely can be caused to gush out from dumping pit 17, be not easy to reclaim, two is because catalyst directly contacts with the sealing original paper of dumping pit 17, likely can cause corrosion to sealing original paper, cause leakage, thus the effect of impact extraction.
