Description

一种多功能提取设备 技术领域
本发明涉及中草药提取技术领域，尤其涉及一种提取设备。
背景技术
目前，大多数中药制药厂或中草药制品厂家，提取中草药应用的仍是传统的提取罐，并采用提取罐夹套通蒸汽的方式对料液进行加热，这种加热方式会导致夹套温度波动较大，不稳定。而且，传统的提取罐，罐体的容体较大，多为2m 3～10m 3，因而在提取固体物料时，不适合机械搅动，通常是采取罐体外对流的方式使料液缓慢对流，很难获得搅动效果，而且耗时长，能耗大，提取效率低，热源消耗大，提取过程中逸出废气，污染环境。有些厂家对提取罐采用机械搅动料液，但在提取过程中，常发生搅动桨卡料，物液打旋现象，提取效果低。另外，传统的提取罐，在物料提取完毕后，不能有效回收物料吸附的有机溶剂，一方面造成溶剂的损耗较大，另一方面直接排放沾有有机溶剂的物料会造成环境污染。
此外，上述传统的提取罐的提取功能也比较单一，对提取的物料种类有一定限制，可提取的物料种类较少。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
如前文所述，现有技术中用于中草药的提取设备，在使用过程中或多或少存在一定的功能缺陷，因此本发明提出了一种性能更优化的提取设备300。图1示出了本发明的提取设备300的结构示意图。
如图1所示，提取设备300包括适于提取物料的提取模块100，提取模块100适于对物料与溶剂混合后的料液进行提取，以形成提取液并储存。需要说明的是，本发明中的物料例如可以是中草药等，但不限于此。提取物料所采用的溶剂可以是纯水或自来水，也可以是甲醇溶液或乙醇溶液，但不限于此。
根据一个实施例，如图1所示，提取模块100包括提取罐110以及与提取罐110连通的第一冷凝器120。提取罐110包括罐体111，罐体110内适于装入物料与溶剂混合后的料液，罐体111的壁部设有夹套112。罐体111的顶部和底部分别设有第一导气管113和第二导气管114，第一导气管113、第二导气管114均分别与蒸汽管和空压气管连接，且蒸汽管和空压气管上分别设有阀门，从而通过控制阀门的开关控制蒸汽、空压气体向第一导气管113、第二导气管114导入，并由第一导气管113和第二导气管114向罐体111内导入蒸汽和/或空压气体。另外，罐体111顶部的第一导气管113还设有喷气管119，喷气管119由第一导气管113向下延伸至罐体111的下部，从而由第一导气管113导入的蒸汽或空压气体，能通过喷气管119从罐体111的下部流入罐体111内。
在提取过程中，先通过第一导气管113或第二导气管114导入蒸汽直接对料液进行加热，并将料液加热到提取温度，以便在提取温度对料液进行提取得到提取液。需要说明的是，提取液是通过在提取温度下持续通过空压气体搅动料液，使物料与溶剂充分、均匀混合后，物料中的有效成分被提取到溶剂中所得到的提取溶液。其中，提取温度、加热时间等参数可以由本领域技术人员自行设置，本发明对此不做限制。
进而，在通过蒸汽将料液加热到提取温度后，停止导入蒸汽，并向提取罐110的夹套112内循环通入预定温度的热水，对使罐体111内的料液辅助加热，使维持在稳定的提取温度。这样，在蒸汽直接对料液加热到提取温度后，通过循环热水对提取罐110的夹套112进行辅助加热，有利于稳定地控制提取温度，而且节约能量。应当指出，在加热过程中，还通过第一导气管113从罐体110的顶部导入空压气体，或者通过第二导气管114从罐体110的底部导入空压气体，通过导入空压气体对料液进行搅动，从而使料液的空间温度均匀，同时使提取物料中的有效成分充分进入提取液中，获取更高的提取效率。
具体地，提取设备300包括蒸汽加热器160，蒸汽加热器160通过蒸汽管分别与第一导气管113、第二导气管114连通，以便向罐体111内导入蒸汽为料液提供热量。蒸汽加热器160可以为电热炉。
如图1所示，提取设备300还包括水循环温度控制机170，夹套112上设 有进水口和出水口。水循环温度控制机170通过热水管分别与夹套112的进水口和出水口连通，从而形成密封循环的加热体系，向夹套112内通入循环热水，对罐体内的料液进行辅助加热，使料液处于稳定的提取温度。水循环温度控制机170可以是微控数值化加热设备，其可以按需求设置水温且水循环温度控制机170上设有数字化显示的进水温度、出水温度、当前水温度以及设置水温度，从而能自动调控加热温度或者停止加热。可选地，水循环温度控制机170的加热温控范围为25～98℃。
提取设备300还包括空气储罐140和空压机145，空压机145与空气储罐145连接，空压机145适于压缩气体，以形成空压气体通入到空气储罐中储存。空气储罐140通过空压气管分别与第一导气管113、第二导气管114连通，从而由空压气管输出的空压气体可通过第一导气管113或第二导气管114导入至罐体111内。空压气体可包括空气、氮气、惰性气体等。
进一步地，空气储罐140还连接有空气油水分离器141。由于空压机145压缩空气会产生含油废水，通过设置空气油水分离器141，能过滤空气储罐140输出的空压气体夹带的含油废水，从而净化空压气体，提高通入至罐体111内的空压气体的纯净度。
另外，如图2和图3所示，罐体111的底部设有排渣口101，排渣口101处设有适于封堵排渣口的排渣口盖102。根据一种实施方式，提取罐110还包括气动装置105，并适于通过该气动装置105控制排渣口盖102打开或关闭，排渣口盖102的开启动力源是空压气体。
根据一个实施例，如图1所示，罐体111的顶部设有排气口115，罐体111内导入的空压气体会通过排气口115排放。该排气口115与第一冷凝器120之间连接有排气管117，从而，第一冷凝器120与罐体111通过该排气管117连通。由于空压气体在排放时会夹带溶剂蒸汽，通过设置与罐体111连通的第一冷凝器120，使空压气体与夹带的溶剂蒸汽均通过排气管117进入第一冷凝器120，并通过第一冷凝器120对溶剂蒸汽冷凝后回收，从而能防止提取罐110内的溶剂损失。
进一步地，如图1所示，第一冷凝器120的下方设有集液器125。集液器125的顶部(进液口)与冷凝器用管连通，集液器125的底部(出液口)与罐 体111连通。空压气体夹带的溶剂蒸汽在第一冷凝器120内冷凝后，会流入集液器125内回收，并能从集液器125的出液口回流至罐体111内提取物料。这样，随空压气体排放的溶剂能重新被利用，一方面减少了溶剂的流失，另一方面防止溶剂排放到大气中污染环境。
如图1所示，提取模块100还包括水箱130，水箱130与集液器125连通。未经第一冷凝器120冷凝的空压气体以及少部分未冷凝的溶剂蒸汽，在进入集液器125后，会继续流经水箱130水洗后排出，进一步防止溶剂蒸汽直接排放到大气中污染环境。
另外，如图1所示，排气管117上还连接有进水管，该进水管上设有手动阀，以便通过手动阀控制进水管开启后，能向排气管117内通入水流，从而清洗排气管117内的物料残渣。此外，排气管117上靠近排气口115的一端还设有滤网装置116，滤网装置116能拦截空压气体排放时夹带的物料颗粒，防止物料颗粒随空压气体进入第一冷凝器120内。
需要说明的是，在对料液提取完成后，还可继续向罐体111内导入空压气体和水蒸气，空压气体和水蒸气可形成合力，并携带走物料残渣吸附的溶剂从排气口115排出、并进入第一冷凝器120冷凝，冷凝后的溶剂进入集液器125，未冷凝的气体则流经水箱130水洗后排放。这样，能实现对物料残渣吸附的溶剂进行回收，降低溶剂的损耗，也避免了溶剂直接排放而污染环境。
根据一个实施例，本发明的提取设备300还能通过蒸馏法从植物香料中提取香油。植物香料例如可以是植物花瓣、植物枝叶、根皮等，但不限于此。具体地，提取罐110还包括筛板118，筛板118可拆卸地安装于罐体111内。当需要通过蒸馏法从植物香料中提取香油时，通过将筛板118安装在罐体111内，在筛板118上放置要提取的植物香料。通过第二导气管114从罐体111的底部导入蒸气，从而，植物香料中的有效成分随蒸汽蒸馏形成蒸馏气，实现对植物香料中的有效成分进行蒸馏提取。
进一步地，如图1至图3所示，提取模块100还包括油水分离器160，油水分离器160与第一冷凝器120连通。植物香料中的有效成分随蒸汽蒸馏形成的蒸馏气由排气管117流入第一冷凝器120，并通过第一冷凝器120冷凝形成蒸馏液，进而，蒸馏液流入油水分离器160，并在油水分离器160内进行油 水分离，从而提取香油。另外，油水分离器160上还设有出油口161，从而将提取的香油从出油口161导出。
需要说明的是，在通过蒸馏法从植物香料中提取香油时，也可以通过第一导气管113或第二导气管114向罐体111内导入空压气体，从而空压气体和水蒸气可形成合力，有助于更快速、充分地对植物香料中的有效成分进行蒸馏提取。
此外，如图1所示，提取模块100还包括储液罐150和过滤器155，储液罐150适于储存提取完成后的提取液。具体地，罐体111的底部连接有提取液管151，并通过提取液管151与过滤器155的进液口连通，过滤器155的出液口与储液罐150连通。这样，过滤器155分别与罐体111和储液罐150连接，当罐体111内的料液提取完成后，通过开启提取液管151，将提取液从罐体111内导出并进入过滤器155过滤，进而，过滤后的提取液再导入储液罐150。
根据一个实施例，提取设备300还包括浓缩器200，浓缩器200适于对提取液进行浓缩。可选地，浓缩器200为单效浓缩器或多效浓缩器。
根据一种实施方式，如图1所示，浓缩器200为单效浓缩器，该单效浓缩器包括加热室210、蒸发室220、第二冷凝器230以及收液罐240。
其中，加热室210可与储液罐150连通，从而储液罐150内的提取液可导入加热室210内，且加热室210通过蒸汽管与蒸汽加热器160连接，从而加热室210可通入蒸汽对提取液进行加热。需要说明的是，加热室210与储液罐150之间也可以是不连通的独立状态，储液罐150内的提取液可通过药液泵抽入加热室210内，并在加热室210内通过蒸汽进行加热。
另外，加热室210的上部与下部分别通过循环管与蒸发室220连通，蒸发室220的顶部与第二冷凝器230连通，收液罐240位于第二冷凝器230下方并与第二冷凝器230通过导管连接。这样，提取液经加热室210加热，并借助抽真空外力从上部的循环管流入蒸发室220，并在蒸发室220分离为二次蒸汽和提取液。经蒸发室220分离后的提取液可通过下部的循环管回流到加热室210内，再次经加热室210加热后流入蒸发室220，形成对提取液的循环加热和蒸发，实现提取液的浓缩。而经蒸发室220分离后的二次蒸汽会进入 第二冷凝器230冷凝为液体，并通过导管导入收液罐240内。
根据一种实施方式，如图4所示，收液罐240为双层结构，包括上下两层，且上下两层通过导液管245连通，收液罐240上层的液体可通过导液管245导入至下层，导液管245上设有阀门。这样，当下层液体收集到一定量时，可关闭导液管245阀门，将下层的液体排出，进而再打开阀门，使收液罐240的上下两层连通，上层液体又能通过导液管245导入至下层。可见，本发明通过浓缩器200能对提取液中的溶剂不断蒸发并冷凝回收到收液罐240内，进而实现对提取液持续的浓缩。
如图1所示，蒸发室220的壁部也设有蒸发室夹套222，该蒸发室夹套222与水循环温度控制机170也通过热水管连通，从而通过向蒸发室夹套222内通入循环热水，为蒸发室220内分离后的提取液提供热量，保证循环进入加热室210的提取液具有较高的温度，提高浓缩效率。
此外，如图1所示，提取设备300还包括抽真空装置250，抽真空装置250与第二冷凝器230连接，能抽取蒸发室220中蒸发的气体。换言之，蒸发室220中蒸发的气体流入第二冷凝器230中，并被抽真空装置250抽走。具体地，抽真空装置250包括第三冷凝器251、真空缓冲罐252和真空泵253，真空泵253可以是水环真空泵，但不限于此。第三冷凝器251分别通过抽真空管与第二冷凝器230和真空泵253连接。真空缓冲罐252位于第三冷凝器251下方并与第三冷凝器251连通。这样，通过真空泵253能将蒸发室220中蒸发的气体(经过第二冷凝器230)抽取至第三冷凝器251中进一步冷凝，并将第三冷凝器251中未冷凝的气体抽走；经第三冷凝器251冷凝后的液体则进入真空缓冲罐252中。
应当理解，真空泵253可将蒸发室220、第二冷凝器230及第三冷凝器251均抽成真空状态。通过抽真空装置250抽取蒸发室220中蒸发的气体，能使浓缩器200内处于负压环境，使提取液在负压环境下更快速地达到浓缩要求。另外，通过设置第三冷凝器251和真空缓冲罐252，对第二冷凝器230中未冷凝的气体进一步冷凝，从而使浓缩器200内达到稳定的真空度，而且能缓冲浓缩罐内外的压力差，防止倒灌。
根据一个实施例，提取设备300还可以设置萃取罐(图中未示出)，通 过将萃取罐与浓缩器200连通，具体可与加热室210的出口连通，从而，在浓缩器200中的提取液浓缩完成后，通过对浓缩器200加压、或者对萃取罐减压，使浓缩器200与萃取罐之间产生压力差，从而便于将浓缩器200中的浓缩流体导入萃取罐内，并在萃取罐内对浓缩液进行萃取。
