Description
Technical field
The present invention relates to a kind of Gutta extraction device, specifically refer to spiral, annular two-stage series gutta-percha leaching device.
Background technology
Gutta-percha is present in folium cortex eucommiae, skin and fruit.Gutta-percha is identical with chemistry of natural rubber composition, but molecular structure is different, and gutta-percha is using trans-polyisoprene, and natural rubber is cis-polyisoprene.Because gutta-percha molecule of the same race is because vulcanization is different, not only can present rubbery state but also can present different plastics states, thereby gutta-percha has very important using value, be a kind of emerging and functional material of serving many purposes.
Gutta-percha is soluble in the non-polar solvens such as benzinum, after adopting the non-polar solvens such as benzinum to extract, lower the temperature to freeze again and analyse and gutta-percha crystal can be separated out to separation, but the extraction of gutta-percha belongs to new industry, the proterties of bark of eucommia material is also comparatively unique, almost there is no mature experience and the technology that can use for reference, it is feasible with the benzinum of 60-90 ℃ of boiling range, gutta-percha being carried out to hot dipping goes out, but the solubility of gutta-percha in benzinum is less, and be easy to form the infiltration that affects solvent as nasal mucus shape, material is tied as soft board, has been difficult to leaching operation; If take conventional grease leaching system, exist the series such as high, the difficult infiltration of little, the molten consumption of solid-liquid ratio, difficult precipitation, difficulty are evaporated, easy obstruction difficult, the industrialization leaching that realize gutta-percha operates, the brand-new gutta-percha leaching device of necessary design.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, provides a kind of perfect in shape and function, leaching effect is good, energy consumption is lower, can realize spiral, annular two-stage series gutta-percha leaching device that serialization is produced.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
A kind of spiral, annular two-stage series gutta-percha leaching device, comprise spiral infuser and loop type extractor, it is characterized in that: spiral infuser is tilted to placement, between two infusers, being provided with materail tube is connected with solvent pump, the low side of spiral infuser is connected with inlet valve, and loop type extractor is provided with leached mud outlet; The low side of spiral infuser connects the temporary tank of overflow leachate through valve, the temporary tank of overflow leachate connects solvent pump through valve, solvent delivery side of pump connects ratio evaporation concentrator, ratio evaporation concentrator connects to freeze through valve on the one hand analyses separator, freeze and analyse separator through the tube side of valve connection tubular heat exchanger, the tube side of tubular heat exchanger connects spiral infuser; Ratio evaporation concentrator also connects the tube side of another tubular heat exchanger on the other hand through valve, the tube side of tubular heat exchanger connects loop type extractor through valve.
