The utility model solves the technical scheme that its technical problem adopts: a kind of continuous contra-flow extraction device with heater, comprises frame, reductor, dog-house, sample tap, cylindrical shell, spiral propeller, solvothermal device, liquid outlet, slag-drip opening; Described reductor is fixed in frame, is connected with spiral propeller by shaft coupling; Spiral propeller is placed in cylinder lumen; Cylindrical shell is arranged in frame, and top, the cylindrical shell face of cylinder is provided with dog-house near the side of reductor, and opposite side is provided with solvothermal device, is provided with sample tap in the middle part of cylindrical shell; Side near reductor bottom the cylindrical shell face of cylinder is provided with liquid outlet, and opposite side is provided with slag-drip opening.
Described cylinder body outer wall is wrapped in ribbon heater, to control the temperature in leaching process.
Described spiral propeller is made up of rotating shaft, spiral plate, and spiral plate is arranged in rotating shaft.
Described spiral plate is 70mm near the pitch of feed end, and interlude pitch is 60mm, and discharge end pitch is 50mm, and material is progressively squeezed in progradation, is conducive to extract in cell and extrudes.
The feed end of described spiral plate, the spiral rotating direction of interlude are dextrorotation, and the spiral rotating direction of the spiral plate of discharge end is left-handed, can effectively prevent material in the accumulation of discharging section.
Described spiral plate is provided with uniform liquid pass hole, distributes in equilateral triangle; Be convenient to solution smooth flow in pipeline.
Described solvothermal device is exported formed by overcoat, inner ring, agitator, water-bath import, inlet, water-bath; Inner ring is set in overcoat, forms confined space; Overcoat side is provided with water-bath import, and opposite side is provided with water-bath outlet, and water-bath outlet is positioned at the top of water-bath import; Inner ring center is provided with agitator, and bottom surface is provided with inlet.
The utility model, a kind of continuous contra-flow extraction device with heater, when extracting material, can reach the heating-up temperature of solvent by controlling bath temperature.The bottom of solvothermal device has an inlet to communicate with cylindrical shell, the outflow of solvent is controlled by the valve installed, controlled the flow of solution simultaneously by control valve, flow directly into the cylindrical shell of continuous dynamic countercurrent extraction equipment from solvothermal device solution out.During extraction, material enters extractor by gravity from feed end, is carried by the helical axis forward end of centre; In leaching process, the moving direction of raw material and solvent is contrary, and the two contacts fully under the effect of transmission mechanism, thus completes extraction.When extraction completes, material slag is constantly separated with extract, discharges respectively, and then achieve Continuous Countercurrent Extraction from equipment two ends.
A kind of continuous contra-flow extraction device with heater of the utility model, its beneficial effect is:
1) continuous contra-flow extraction device of this band heater adopts full-automatic function mode, and operating platform is easily understood, and only needs a common staff to train the just independent operation on duty of energy a little;
2) continuous contra-flow extraction device of this band heater has hygiene, compact, easy for installation, long service life, low-cost advantage;
3) continuous contra-flow extraction device of this band heater has higher recovery rate and extraction efficiency, and solvent load is few.
