Description
Technical field
The present invention relates to a kind of Gutta-percha freeze-out device, specifically refer to the device be separated from the organic solvent dissolving gutta-percha by gutta-percha.
Background technology
Gutta-percha is a kind of emerging and functional materials served many purposes, there is important using value, the non-polar solvents such as usual employing sherwood oil extract from the plant tissue of the bark of eucommia, the non-polar solvents such as the sherwood oil of heat are soluble in due to gutta-percha, in the non-polar solvents such as cold sherwood oil, solubleness is very low, therefore, frozen cooling is carried out to the solution having extracted gutta-percha, gutta-percha can crystallization, but adopt common dividing wall type frozen cooling that gutta-percha can be made slowly to separate out, viscosity promotes rapidly, cannot transmission of heat by convection, heat transmission resistance can be increasing, lower the temperature very slow, the gutta-percha of separating out forms cotton-shaped suspended substance in the solution gradually, be difficult to be separated completely with organic solvent, even if separation also can cause the loss of a large amount of organic solvent reluctantly, not only waste resource but also contaminate environment, this has seriously perplexed the industrialization production process of gutta-percha.
It is slow that existing general freezer equipment and tripping device cannot solve cooling in gutta-percha Crystallization Process, the gutta-percha of separating out forms cotton-shaped suspended substance in the solution, gutta-percha and organic solvent are difficult to the technical problem be separated, and thus, prior art can not meet the demand that gutta-percha industrialization is produced.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, and provide a kind of perfect in shape and function, heat exchange efficiency is high, and cooling rate is fast, and the gutta-percha after crystallization is easy to be separated, the Gutta-percha freeze-out device that solvent loss is few.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
A kind of Gutta-percha freeze-out device, comprise freezing and analyse tank and water tank, it is characterized in that: freeze and analyse tank and be provided with into gutta-percha solvent valve, freeze to analyse in tank and be provided with multiple nozzle, freeze to analyse tank upper end and water tank upper end and freeze and analyse tank lower end and water tank lower end realizes UNICOM respectively by equilibrium valve and coupling cock, UNICOM can make the pressure equilibrium on two tank body tops, and the water of tank body lower part also can flow on demand; Water tank lower end forms water-flow circuit through pump, interchanger and water tank upper end, and interchanger and frozen water machine form water for cooling loop, by arranging the lesser temps that these two loops can make the water of water tank reach required; Water tank lower end through pump, spray control valve, freeze and analyse nozzle in tank and coupling cock forms upper spray loop, water tank lower end also forms lower gusher loop through pump, end spray control valve and coupling cock, and the water through upper spray loop and the ejection of lower gusher loop is analysed coupling cock between tank and water tank be back to water tank by being frozen; Freeze and analyse tank top through centrifugal filter, skimmer and water tank UNICOM, unicom pipeline is arranged solvent refluxing valve, frozen water reverse flow valve and other valve, both convenient operation, the organic solvent after separatory and water can be recycled again.
The pipeline in described water-flow circuit, water for cooling loop, upper spray loop and lower gusher loop can arrange multiple valve as required, be convenient to actually operating.
Described skimmer, freeze and analyse tank and water tank can be provided with wash water valve, be convenient to carry out blowdown process.
Described skimmer, freeze and analyse tank and water tank can be provided with liquidometer, be convenient to check liquid level.
The skimmer that in system, temperature is lower, interchanger, freeze and analyse tank, water tank and pipeline and carry out reasonable isothermal holding.
Compared with prior art, beneficial effect of the present invention is: by arranging the pump circulation mode in upper spray loop and lower gusher loop, realize gutta-percha solution and refrigerated water direct contact heat transfer and fast cooling crystallization, avoid the suspended substance that gutta-percha solution makes because temperature slowly declines the gutta-percha of precipitation become cotton-shaped, be conducive to the loss that follow-up gutta-percha is separated and reduces solvent; Because the non-polar solvent such as water and sherwood oil is immiscible, and the density of water is greater than the density of the non-polar solvents such as sherwood oil, therefore, after gutta-percha crystallization completes, water can be in the lowest layer, freeze and analyse glue and to mediate layer, and the non-polar solvent such as sherwood oil after resolving occupy the superiors, the present invention is by arranging centrifugal filter and skimmer, the separation completely of water, solvent and gutta-percha can be realized very easily, again by arranging solvent refluxing valve and other multiple valve, achieve recycling of the water after separation and solvent.
Apparatus of the present invention are integrated by above multifunction module, achieve quick, the efficient crystallization of gutta-percha, and after gutta-percha crystallization, can easily gutta-percha, water and organic solvent be effectively separated and recycle, sepn process can accomplish that organic solvent is substantially lossless, function is very perfect, and device structure is also relatively simple, and commercial application has a extensive future.
