Description
Technical field
The utility model relates to a kind of being used for the continuous crystallisation in enormous quantities of materials such as chemical and fine chemicals, medicine, food or the crystallizer of gap batch crystallization, is specifically related to a kind of hollow plate cooling of wall type continuous crystallisation machine of efficiently scraping.
Background technology
As everyone knows, the crystallisation by cooling of material is a medicine, and the crucial unit operations of industries such as chemical industry, food, directly influences the output and the quality of product at the quality of crystallization.
At present with the most use is the kettle type crystallization device, this equipment is to add cooling jacket at the kettle that a band stirs to come material is carried out crystallisation by cooling, or, in still, add cooling coil etc. again material is carried out crystallisation by cooling except adding at kettle cooling jacket cools off.Though this legacy equipment can solve common crystallisation problems, also has many shortcomings:
1. owing to adopt the chuck cooling, crystallization makes crystalline thing at first tie at the still wall at first from the still wall, can form thick crystalline thing on the still wall when serious, influences heat transfer efficiency greatly; Though can reduce the problem of crystallization on the still wall by the method that improves speed of agitator, but crystallization also is subjected to the restriction of speed of agitator under many circumstances, speed of agitator is too fast, the particle diameter of crystal grain is reduced greatly, influence next step filtration washing drying process, and obtain the occasion of crystal grain greatly for hope, improper especially.Still formula stirred crystallization in addition, paddle generally are difficult to accomplish to scrape wall and stir, and so just the crystal grain of tying on the still wall can not be scraped, thereby influence heat-transfer effect.
2. common crystallization kettle is often better at the crystallization effect near external refrigeration still wall, and very slow in the material crystallization near the still center, causes that crystal grain is inhomogeneous, and whole crystallization rate is slower.
3. in still, adding the crystallization kettle of cooling coil,,, outside static coil pipe, form crystallization earlier, have a strong impact on heat-transfer effect because cooling coil is static though can improve film-cooled heat greatly.Add the mixing effect that can influence crystallization kettle behind the coil pipe greatly in addition, scrape wall and stir and to accomplish that especially after forming more crystalline thing on the still wall and on the coil pipe, heat-transfer effect is poorer, and slurry can not successfully be discharged fully.
4. the bottom owing to crystallization kettle often is a standard elliptical head, thereby higher for material concentration, the crystallization kettle that crystalline solid is more, and often discharge is not thorough, and the partially crystallizable solid can remain in the interior row of still and not go out, and influences output and energy consumption.
Shortcoming at above-mentioned common kettle type crystallization machine existence, research institution had once developed horizontal interior disk crystallisation by cooling machine, horizontal interior commentaries on classics comb crystallisation by cooling machine, horizontal interior commentaries on classics ribbon crystallisation by cooling machine, the pusher continuous crystallisation by cooling machine of horizontal cored screw, vertical interior commentaries on classics comb crystallisation by cooling machine, the vertical interior ribbon crystallisation by cooling machine etc. that changes of changeing in the industry, crystalline rate is increased, saved energy consumption and reduced crystallization time.
Above-mentioned crystallizer is compared with common kettle type crystallization machine, though efficient increases, but in the process of crystallization, the cooling surface of rotating moving part still has crystal to bear, in case cooling surface has crystal to form, even the thinlyyest also can influence cooling effect, occasion to gap operating, this phenomenon is also very not outstanding, because the crystallized stock of next group heat adds fashionable meeting this layer crystalline solid dissolved, but to the situation of continuous crystallisation, above-mentioned this situation will be very outstanding, because the crystalline solid of cooling surface is can be long-pending more thick more and can't remove and have a strong impact on cooling effect.For this reason, demand urgently developing and a kind ofly can cooling surface be remained totally, thereby improve the crystallizer of crystalline rate.
