Description
Technical field
The utility model relates in analyses such as petrochemical industry, metallurgy, medicine, biology, environment, geology technology and the research and development technical field realizes a kind of filter that solid-liquid separates mutually fast, particularly a kind of under the heat tracing state realization solid-liquid a kind of filter of separation fast mutually continuously.
Background technology
Filtration is a kind of method of the solid matter that is insoluble to liquid with the liquid phase separation, is to realize the most general conventional unit process of Separation of Solid and Liquid application in commercial production and the research and development field.Exist multiple important solidliquid mixture in the commercial production,, need carry out carrying out constituent analysis mensuration after the Separation of Solid and Liquid, realize industrial quality control it like various waste water, plating bath, lysate, zymotic fluid, mud, sedimentation liquid etc.In the research and development field; The solid crude product of separating from organic synthesis often contains unreacted raw material, accessory substance and impurity; Separation and purification in addition; Some the interior technical process that are prepared in that comprise solvent extraction, solvent recrystallization, analytic sample all relate to Separation of Solid and Liquid, and one of method that the realization Separation of Solid and Liquid is the most frequently used is exactly to filter.
According to the difference of the character of each composition in the mixture, distinct methods such as common filter method can be divided into that normal pressure filters, filtration under diminished pressure (being suction filtration) or heat filtering, heat filtering are divided into again that ordinary hot is filtered and two kinds of decompression heat filterings.Heat filtering and suction filtration are to realize one of solid-liquid fast separating process, have overcome the shortcoming that the normal pressure rate of filtration is slow, fractional dose is little, and not only separating rate is fast but also separative efficiency is higher relatively for it.If adopt conventional method to filter, then the rate of filtration very slowly prolongs filtration time, so the experimenter generally is ready to adopt the mode of heating or suction filtration.Some filter operation also must be adopted the mode of suction filtration in addition, because suction filtration not only can accelerated filtration, shortens filtration time, can also inhale sediment relatively drylier, reduces water capacity, and is dry easily.Then must under heat tracing, carry out like solvent extraction, solvent recrystallization process in some aspects, separate out, cause product loss otherwise filter process has crystallization, metering or to analyze data inaccurate, filtering velocity slows down etc.
Common suction filtration device comprises: Buchner funnel, bottle,suction, safety flack and air-extractor.Earlier filter paper is placed in the Buchner funnel and wetting it, again Buchner funnel is placed in the water-bath with hot water or Steam Heating, perhaps in baking oven after the heating, completion filter operation under vacuum pressure then.But because filter operation is a natural temperature-fall period, in many cases (if any crystallization separate out, high condensation point material or comparison ropy material system) even adopt the suction filtration mode still can not meet the demands, do not reach the filter effect of anticipation.
At present, it is that common funnel is placed in the copper heat leak bucket that ordinary hot is filtered, and in the copper heat leak bucket hot water is housed, to keep necessary temperature.Water filling from water injection hole thermotropism filter tunnel interlayer during operation, the heated funnel side pipe makes the water temperature in the funnel reach requirement, filters and under hot water thermal insulating, carries out.This mode can only atmospheric operation, and filtration temperature can not be controlled, and can only handle easy filtration and measure few material system.
No matter be that common filtration, ordinary hot are filtered or suction filtration, all can only partly solve the problem that runs in the Separation of Solid and Liquid process.In some occasion; Under the situation that reduction of feed volume is big, solid content granularity viscosity tiny, feed liquid is big of filtering, perhaps when carrying out filtration experiment, need stable filtercondition (especially temperature) when measuring the rate of filtration, then need keep long filtration time; In addition when filtering hot saturated solution or approaching saturated solution; Often cause in funnel or its neck is separated out crystal, make to filter difficulty takes place, at this moment will carry out heat filtering because of cooling.For some material system, even adopt the heat filtering effect also undesirable.Because the filter process variation of temperature is difficult to obtain comparatively ideal results.In order further to improve the rate of filtration and the filtration filtration problem that solves the material system that is difficult to filter; Make liquid and solids leave fully; Obtain filter effect preferably, then consider filtered off with suction and heat filtering are combined, decompress filter and heat filtering are also used simultaneously; Both heat filterings under the vacuum condition is to reach the separation purpose of expection.
At present, the Bu Shi that domestic and international chemical laboratory generally uses leaks meter and conventional bottle,suction, at recrystallization process; Particularly in the synthetic recrystallization process of semimicro; Although vessel are preheating in advance, in the heat filter owing to cool off very soon by air, cause Lou count in the too early crystallization of hot saturated solution; Stop up filter opening, reduce yield.Simultaneously, also because of early being analysed by the air cooling, be difficult for inclining the saturated solution that leaches in the bottle,suction.To the drawback that exists on the at present existing filtering technique equipment, Chinese patent CN91226168.4 has proposed a kind of novel filtration and suction filtration device, and the utility model has been set up a water filling heating interlayer, thereby has improved yield greatly.Conversely, utilize interlayer to inject that cold water can make crystallization at low temperatures and the product that under higher temperature, can dissolve is avoided losing.The conventional Bu Shi that uses of the utility model leaks meter and bottle,suction, and filter effect improves, but its structure is comparatively complicated, and pottery and glass material processing acquire a certain degree of difficulty; On the other hand, once adding hot water can only keep the short period, along with the carrying out of filter process; Temperature is more and more lower; Speed is more and more slower, and during filtration time that especially the filter material amount is big or the tiny needs of solid content granularity are long, the improvement of filter effect is just not obvious.
Laboratory shopping guide's net (http://www.labguide.cn/goods-707.html) discloses a kind of heating jacket that is applicable to the matching used TM of various funnels series, and the temperature that it can the real-time ensuring hopper walls has solved the transmission problem of high condensation point liquid.Can select annular support, and be fixed on receiving vessel top to this heating jacket.This heating jacket can satisfy the needs of heat filtering to a certain extent; But to be equipped with support in addition; Use not very conveniently, the main problem of existence is not have temperature control system, causes overtemperature easily; And the filter process temperature fluctuation is bigger, and situation about will aspire for stability for temperature sensitive material or filtration temperature is difficult to meet the demands.
Remove the above, also do not see the heat filtering device of other type at present.
