The invention belongs to the technical field of extraction kettles, and more specifically relates to a
supercritical carbon dioxide fluid extraction kettle. The
supercritical carbon dioxide fluid extraction kettle comprises a pedestal, a placing cavity, a sliding plate, elastic rubber columns, springs, supporting legs, supporting cylinders, fixing bolts, placing shells, electric push rods, connecting plates, fixing shafts, rollers, an extraction kettle body, a heating shell, a heating wire, an air outlet
pipe, an air outlet valve, a mounting base, a top cover, a fixing base, fastening bolts, an air inlet
pipe, a connecting main
pipe and connecting
branch pipes. According to the
supercritical carbon dioxide fluid extraction kettle, the supercritical
carbon dioxide fluid extraction kettle can be automatically supported; it is convenient for workers to move and adjust the placement position of the supercritical
carbon dioxide fluid extraction kettle; labor intensity of workers is reduced;during use, under the action of an adopted clamping damping mechanism, the extraction kettle main body placed on the surface of the pedestal can be conveniently and stably clamped and fixed, meanwhile, the damping effect of the extraction kettle main body in the moving process can be conveniently improved, and under the action of an adopted heating mechanism, the extraction kettle can be conveniently assisted to effectively increase the temperature in the extraction kettle.
