Description

分离介质浆料储罐
本发明的技术领域
根据权利要求1，3和7的前序部分，本发明涉及用于使分离介质浆料悬浮的方法和储罐。
发明背景
分离介质例如可以是层析介质和密度梯度介质。该介质例如可以是基于自然聚合物粒子或合成聚合物粒子或无机材料的树脂。对于层析技术，需要将分离介质提供至层析柱中。对于分离介质输送到例如柱中，首先需要使介质悬浮在均质的介质浆料混合物中。分离介质通常悬浮在液体，例如水、缓冲剂或溶剂中。这种悬浮的介质通常被称为介质浆料。当将要利用来自存储容器的介质浆料填充柱时，使用浆料在其中混合成均质混合物的中间储罐。在储罐中，介质浆料时常被手动搅拌，并且关于不同大小的粒子在介质中的分布，重要的是使介质浆料变成均质的混合物。当然手动搅拌是不方便的，特别是当有大量的介质浆料有待搅拌时。用介质浆料填充柱还可能发费相当长的时间，并且在整个时间内都需要搅拌介质浆料。有时使用的用来混合浆料的另一方式是使储罐来回摇晃或倾斜。这对于小的储罐和少量的浆料可能是有利的，但其难以执行并且不适用于大的重的储罐。
在例如EP0515955或JP4323557中已经提出了解决方案，其中使用了永久的电动搅拌器(也称为推动器)。然而其存在与这种推动器相关联的不同的问题。如果推动器不运转，那么在介质浆料处于储罐内部的整个时间内，浆料将沉积，并且将难以在沉积的介质中起动推动器。这需要更加大型的发动机。当在沉积的介质中起动推动器时，介质粒子可能由于推动器提供的剪切力而受损。为了最大限度地减小可能由推动器造成的对粒子的损伤，可优选不使推动器在整个时间内都运转。
概述
本发明的一个目的是提供一种用于在将介质浆料输送到例如其中所述介质中的粒子不会受损的柱之前使所述分离介质浆料悬浮的改进的方法和储罐。
这通过根据权利要求1所述的方法和根据权利要求3所述的储罐以及根据权利要求7所述的储罐系统来实现。
因而推动器不需要在厚实的沉积的介质中起动(其具有损坏介质中的粒子的风险)，并且推动器不需要在分离介质处于储罐内部的整个时间内都运转。由喷嘴进行的液体喷洒使介质从储罐的底部开始重新-悬浮，并且当介质已经充分重新悬浮时可起动推动器。此外，来自已经开始沉积的介质浆料的液相的液体被喷嘴用于喷洒，并因而不需要添加新的液体，且从而可使浆料浓度保持恒定。
在从属权利要求中描述了另外的合适的实施例。
图纸简要说明
图1是根据本发明的分离介质浆料罐的示意图。
图2是描述该方法步骤的流程图。
实施例的详细描述
图1是根据本发明的分离介质浆料罐1的示意图。如果从介质存储容器将介质供给至柱，则首先将介质从存储容器传送至根据本发明的介质储罐。
这可通过将管道从存储容器连接至结合介质浆料罐一起提供的泵3上来实现。所述泵还连接在具有设于储罐1内部的开口端6的可调管道5上。以下将进一步描述所述可调管道5。因此，可将介质浆料从介质存储容器泵送至储罐中。或者可利用另一泵和某些其它管道或管件而将介质从存储容器传送至储罐。
当介质已经被传送至储罐中时，其立即开始沉积。设于储罐内部的推动器7可从开始时就起动，并在整个时间内保持搅拌介质浆料，直至介质已经被传送至柱中，在柱中介质将用于例如层析，但根据本发明，如以下将进一步描述的，推动器不需要在整个时间内都运行。在储罐的高度方向上优选将推动器7设计成线圈，这种推动器也称为螺旋带。然而其它设计，例如形成锚件的双叶或三叶螺旋桨或推动器也是可行的。图1中显示了双叶螺旋桨7。此外，推动器适合提供为使其最下端接近于储罐的底部8。
根据本发明，还提供了从储罐的底部8突入到储罐中的喷嘴9。该喷嘴连接在泵3上，泵3又如上所述连接在可调管道5上。一旦介质浆料开始沉积，就可将可调管道5调整为使其开口端6处于沉积的介质上方所提供的液相中。根据本发明，泵3从液相中泵送液体，使液体通过可调管道5并进一步泵送至喷嘴9。泵对喷嘴中的液体施加压力，并将喷嘴设计成使得液体以某一速度从储罐的底部8引入到(例如喷洒到)沉积的介质中。这具有使储罐中的沉积介质将开始重新悬浮的优势。优选的是，推动器直至沉积的介质已通过喷嘴的喷洒而充分地重新悬浮时才起动。因而起动推动器将比如果推动器必须在厚实的沉积的介质内起动时更为容易，并且最大限度地减小了损坏介质粒子的风险。此外，来自沉积的介质浆料的液相的液体由喷嘴用于喷洒，其意味着不需要提供额外的液体，并可使介质浆料的浓度保持恒定。
在介质浆料已充分搅拌和混合时，可将其通过管道11而从储罐1的底部传送至柱中。
当将介质从柱传送至存储容器中时，也可使用根据本发明的储罐。可能较为合适的是首先将介质传送至储罐中，根据之前所述的内容使介质充分悬浮，且之后将介质浆料传送至存储容器中。
现在将参照图2中的流程图进一步描述根据本发明的一个实施例的通过储罐而将介质浆料从存储容器传送到柱的方法。这些步骤按以下顺序进行描述。
S1：首先将介质浆料从存储容器传送至根据本发明的储罐。这可通过利用泵和管道或管件来实现。可能的是，连接在储罐和储罐的可调管道5上的泵3可用于介质浆料从存储容器至储罐的这种传送。一旦介质浆料已进入储罐，其就开始沉积-实际上其在一定程度上已经沉积，因为在存储容器中没有执行搅拌，即介质将沉积在储罐的底部8上，并且液相(也可能包含某些粒子)将累积在沉积的介质上。
在将介质浆料传送至储罐中之后，不需要立即执行方法步骤S2-S11。但当是时候将介质浆料传送至柱中时，需要将介质浆料混合成均质的介质浆料，且之后将执行步骤S2-S11。
S2：将可调管道5调整为使得其开口端6处于储罐中的液相中。
S3：接下来的步骤是通过利用泵3将来自液相的液体泵送通过可调管道5。
S5：然后通过泵3将液体输送至喷嘴9中。
S7：通过由泵3对喷嘴9施加压力，液体从储罐底部(8)中从喷嘴9中喷出而进入到沉积的介质中。
S9：当靠近储罐底部8的沉积的介质已经被充分地重新悬浮时，推动器7起动。推动器7被驱动，直至获得介质浆料的均质混合物。
S11：当介质浆料得以充分地混合时，将其传送至柱。
如果根据本发明的方法将应用于介质浆料的逆向传送，即从柱传送至存储容器，则遵循相同的步骤S1-S11而仅有如下变化：即存储容器替换柱，且柱替换存储容器。
