Description
Technical field
The utility model relates to a kind of biochemical separator; the tangential flow filtration that belongs to the molecular weight level; especially relate to a kind of employing membrane separation technique; usually molecular cut off is 1-1000KD, is widely used in the tangential flow ultra-filtration unit of bioengineering, bio-pharmaceuticals, chemistry, papermaking, Food Science, ocean engineering and field of environment protection.
Background technology
Ultrafiltration claims hyperfiltration again, is to be one of membrane separation technique of motive force with pressure, utilizes film surface mechanical grading, fenestra retardance and the adsorbing comprehensive effect of film surface fenestra, and reaching big molecule and little molecular separation is purpose.In ultra-filtration process, the aqueous solution film surface of flowing through under pressure promotes sees through rete less than solvent and the little molecule solute of fenestra, becomes cleaner liquid; Solute and the solute group bigger than fenestra are trapped, and discharge with solvent, become concentrate.Ultra-filtration process is dynamic filtration, separation process is finished under flow regime, have easy and simple to handle, with low cost, need not increase the experiment condition gentleness of advantage, the especially hyperfiltration technique of any chemical reagent, compare the variation that does not have phase with evaporation, freeze drying, and do not cause the variation of temperature, PH, thereby can prevent sex change, inactivation and the self-dissolving of large biological molecule.But ultrafiltration also has certain limitation, and it can not directly obtain dry powder formulations.For protein solution, generally can only obtain 10%～50% concentration.
Cross-flow ultrafiltration (Tangential flow ultrafiltration) refers to liquid flow direction and filtering direction ultrafiltration form in vertical direction.The flow direction of traditional vertical its liquid of filtration is consistent with filtering direction, along with the carrying out of filtering, cake layer or gel layer thickness that filter membrane surface forms increase gradually, and flow velocity reduces gradually, so the ability of the processing feed liquid of dead-end filtration is subjected to certain restriction.And cross-flow ultrafiltration produces shearing force on the filter medium surface in the liquid flow process, has reduced the accumulation of filter cake or gel layer, has guaranteed the stable rate of filtration, and this has important role concerning whole filter process.
The key of hyperfiltration technique is film, and film has various type and specification, can select for use according to requirements of one's work.Early stage film is isotropic uniform films, i.e. Chang Yong microporous membrane, and its aperture is 0.05mm and 0.025mm normally.In recent years, some anisotropic asymmetric milipore filters have appearred on the market, a kind of anisotropy diffusion barrier, porous " skin layer " with certain pore size extremely thin by one deck wherein, relative heavy back with one deck many easier to be logical that ooze, form as " spongy layer " that support usefulness.Skin layer has determined the selective of film, and spongy layer has increased mechanical strength.Because skin layer is extremely thin, therefore efficient, permeability is good, flow is big, and be difficult for being blocked by solute and cause flow velocity to descend.Film commonly used generally is to be made by the two mixture of acetate fiber or cellulose nitrate or this.For adapting to the needs of sterilizing in pharmacy and the food industry, developed the anisotropic membrane of non-fibrous type, for example PS membrane, polysulfonamides film and polyacrylonitrile film etc. in recent years.This film all is stable in PH1～14, and can be 90 ℃ of following operate as normal.
Ultrafiltration originated from 1748, but until the sixties in 20th century, proposition along with the molecular level concept, beginning of modern hyperfiltration technique development at last, the seventies and the eighties are the develop rapidly stages of hyperfiltration technique, external hyperfiltration technique just has been tending towards ripe after the nineties, and the diversification of market ultrafiltration commodity is widely used in every field.China is later to this technical research, still is in the research time limit seventies, the end of the eighties, just enter suitability for industrialized production and application stage, technical development at present is in good condition, and many product qualities are not second to external product, but product use still have many worth raisings aspect.
Cross-flow ultrafiltration equipment is mainly based on imported product in the market, the domestic product that has some producers that small-sized or easy cross-flow ultrafiltration are arranged.Film product as technological core has abundant product resource in market, but because developer's difference, model difference between the different film products, need different separately adapting appts, limited the idea that the user wants to carry out abundanter application to a certain extent, therefore, develop one's own moulding cross-flow ultrafiltration product and can accomplish that compatible domestic and international various different film products become a project that receives much concern in this field.
Summary of the invention
In order to overcome the existing domestic moulding cross-flow ultrafiltration equipment that still do not have, the situation of import equipment costliness, the utility model provides a kind of novel tangential flow ultra-filtration unit, this device is in conjunction with the present market demand to cross-flow ultrafiltration equipment, multiple cross-flow ultrafiltration functional part is become one, and with micro computer whole device is monitored, whole cross-flow ultrafiltration process is quantized, visual straight control, easy and simple to handle, the temperature and pressure sensor that carries provides the pressure and temperature data in real time, warning line can be set report to the police automatically, and is safe and reliable; Pipeline junctional membrane bag is directly used in the film chamber, can adaptive various film bag, and it is convenient to change, and maximizes compatible various experimental program.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of tangential flow ultra-filtration unit comprises device case, the LED control flow, the magnetic agitation unit, pump unit, pressure sensitive unit, temperature sensing unit, film chamber, sample jar, circuit board is formed, and the LED control flow is positioned at the housing left side, and sample jar is positioned at the housing right side, be the magnetic agitation unit in the sample jar bottom shell, the pump unit is positioned at enclosure interior, and an end connects sample jar bottom outlet, and an end junctional membrane chamber arrives the film bag; The film chamber is positioned at the instrument rear, and each unit interlock circuit is directly connected on the circuit board of central authorities, by LED control flow and the common regulation and control that realize each unit of circuit board.
Described pump unit adopts the membrane pump of anti-deep-etching, and pump housing size is little, and it is non-maintaining not have oil, quiet microseismic activity during running, and auto-pumping can be done running, and running speed is controlled in real time by the LED control flow.
Described magnetic agitation unit is positioned at the housing of sample jar bottom, adopts slim motor, and running speed is controlled in real time by the LED control flow, evenly rotates by sample liquids in the magneticaction drive sample jar, reaches to make the stable purpose of each component of sample liquid.
