液體傳輸設備用於將液體從一個地方傳輸到另一個地方,常見於工廠或實驗室。傳統的液體傳輸設備藉由閥門來控制液體的導入。然而,上一次傳輸的液體可能殘留管線中,特別是殘留於閥門。閥門也可能被腐蝕而污染液體。 Liquid transfer equipment is used to transfer liquids from one place to another, usually in factories or laboratories. Conventional liquid delivery devices use valves to control the introduction of liquids. However, the liquid from the last transfer may remain in the line, especially in the valve. Valves can also corrode and contaminate the liquid.
在一些領域中,需要嚴格要求液體不受汙染。例如,檢測化學品的純度的實驗室。若送檢測的化學品受液體傳輸設備汙染,檢測就失去了準確度。 In some fields, it is strictly required that the liquid be free from contamination.

It should be noted that the present invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of the present invention. The following embodiments will be described in further detail
The related technical content of the present invention, but the disclosed content is not intended to limit the scope of the patent application of the present invention. The description is as follows: As shown in FIG. 1A , the
輸出端裝置1包括一第一儲存容器11及一第一加壓構件12。第一儲存容器11具有一液體注入口111及一液體輸出口112。液體輸出口112較佳地為設置在靠近第一儲存容器11的底部,以利液體傳輸。液體注入口111較佳地為設置在第一儲存容器11的頂端,或至少高於液體輸出口112,然而本發明不限於此。
The
第一加壓構件12連通第一儲存容器11以對第一儲存容器11灌注高壓氣體。第一加壓構件12例如是工廠的高壓氣體源、高壓氣瓶或高壓氣體增壓泵浦,用以提供高壓的氮氣或惰性氣體。第一加壓構件12選擇性地具有一第一單向進氣閥121。當第一儲存容器11內部的氣壓小於設定的氣壓值,第一單向進氣閥121開啟使第一加壓構件12對第一儲存容器11灌注高壓氣體。較佳地,第一加壓構件12常態性地連通第一儲存容器11,並使第一儲存容器11內部的氣壓保持在三標準大氣壓。然而本發明不限於此,第一儲存容器11內部的氣壓可以為其他數值,並且第一加壓構件12可配置為需要加壓的時候才連接第一儲存容器11。
The first pressurizing
接收端裝置2包括一第二儲存容器21及一氣壓調節構件22。第二儲存容器21具有一液體接收口213。氣壓調節構件22連通第二儲存容器21以調整第二儲存容器21內部的氣壓。
The receiving
在本實施例中,氣壓調節構件22包括一第二加壓構件221及一降壓構件222。第二加壓構件221連接第二儲存容器21以對第二儲存容器21灌注高壓氣體。第二加壓構件221可具有第二單向進氣閥221a。第二加壓構件221的構造、原理與第一加壓構件12相同,不再贅述。
In this embodiment, the air
降壓構件222包括一降壓室222a、一降壓管路222b及一降壓閥222c。降壓室222a內部的氣壓小於第一儲存容器11內部的氣壓及第二加壓構件221的氣壓,較佳地為大於一標準大氣壓(在本實施例中為二標準大氣壓)。降壓管路222b連通於降壓室222a及第二儲存容器21之間。降壓閥222c設置於降壓管路222b。
The
當第二加壓構件221與第二儲存容器21之間為導通,第二加壓構件221對第二儲存容器21灌注高壓氣體,使第二儲存容器21內部的氣壓上升。當第二加壓構件221與第二儲存容器21之間不導通,且降壓室222a藉由降壓管路222b連通於第二儲存容器21,第二儲存容器21的高壓氣體流向降壓室222a,而使得第二儲存容器21內部的氣壓降低。
When the
然而本發明不限於此,在其他實施例中,氣壓調節構件22可以藉由其他方式調節第二儲存容器21內部的氣壓。
However, the present invention is not limited thereto, and in other embodiments, the air
連通管路3連接液體輸出口112及液體接收口213,用以將第一儲存容器11內部的液體輸送至第二儲存容器21。
The
控制裝置4訊號連接氣壓調節構件22,透過氣壓調節構件22調節第二儲存容器21內部的氣壓。控制裝置4例如是控制晶片或控制電路。在本實施例中,控制裝置4分別訊號連接第二加壓構件221及降壓閥222c。
The
接下來說明本發明的液體傳輸設備100如何輸送液體。
Next, it will be explained how the
如圖1A所示,一個外部的給料裝置S經由液體注入口111向第一儲存容器11注入液體。由於第一儲存容器11可能常態地保持高氣壓,因此給料裝置S可藉由針頭或其他加壓給料的方式向第一儲存容器11注入液體。給料裝置S可以為固定於液體注入口111的裝置,也可以為可插拔的裝置。第一加壓構件12可以在給料前或給料後對第一儲存容器11灌注高壓氣體,使第一儲存容器11保持在三標準大氣壓。可以由一個氣壓感測器16感測第一儲存容器11內部的氣壓,進而決定是否啟動第一加壓構件12。第一加壓構件12的啟動可以是手動操作,也可以是藉由控制裝置4自動操作。
As shown in FIG. 1A , an external feeding device S injects liquid into the
當液體注入第一儲存容器11後,液體表面的液體壓力與第一儲存容器11內部的氣壓達成平衡,也就是三標準大氣壓。液體底部的壓力為三大氣壓加上液體高度產生的壓力(液體的密度、重力加速度與液體高度的乘積)。然而在本實施例中,液體表面只需要達到液體輸出口112的高度即可。因此液體高度產生的額外壓力很小,可忽略不計。因此液體壓力也是大約等於三標準大氣壓。
After the liquid is injected into the
如圖1A所示,液體傳輸設備100於非傳輸狀態下,為了要讓液體不經由連通管路3進入第二儲存容器21,控制裝置4藉由氣壓調節構件22(在本實施例中為第二加壓構件221)調整第二儲存容器21內部的氣壓。第二儲存容器21內部的壓力必須不小於第一儲存容器11內部的壓力。並且較佳地,連通管路3至少具有一個往上升(相對於液體輸出口112)的路徑,或是第二儲存容器21內部的壓力大於第一儲存容器11內部的壓力,以有效避免液體不受控制地流入第二儲存容器21。
As shown in FIG. 1A , in the non-transmission state of the
而為了要進一步讓液體停留在第一儲存容器11中(不流入連通管路3),第二儲存容器21內部的壓力最好略大於第一儲存容器11內部的壓力,或是連通管路3的路徑從液體輸出口112就直接往上升。有關壓力控制與路徑高度的細節會在後文進一步探討。
In order to further allow the liquid to stay in the first storage container 11 (not to flow into the communication line 3), the pressure inside the
如圖1B及圖1C所示,液體傳輸設備100於傳輸狀態下,控制裝置4藉由氣壓調節構件22(在本實施例中為降壓構件222)降低第二儲存容器21內部的氣壓,使第一儲存容器11內部與第二儲存容器21內部之間的壓力差足以驅使第一儲存容器11內部的液體流入連通管路3(如圖1B所示)並進入第二儲存容器21(如圖1C所示)。
As shown in FIG. 1B and FIG. 1C , when the
在本實施例中,液體傳輸設備100主要用於提供給實驗室的抽樣檢測系統,因此給料裝置S每次注入的液體體積不大於連通管路3內部的總體積。即,液體在傳輸的時候不會完全充滿連通管路3。然而本發明不限於此,液體傳輸設備100可用在其他需要傳輸液體的系統,並且液體傳輸設備100一次可以傳輸更多體積的液體。
In this embodiment, the
當控制裝置4藉由氣壓調節構件22使第二儲存容器21內部的氣壓降低,第二儲存容器21內部與第一儲存容器11內部存在一氣壓差。此氣壓差推動液體進入第二儲存容器21。在比較好的例子中,控制裝置4可以藉由漸進地打開降壓閥222c,使第二儲存容器21內部的氣壓漸漸地下降。例如在第0-5秒,第二儲存容器21內部的氣壓為2.9標準大氣壓,再經過5秒降至2.8標準大氣壓,以此類推。這樣的方法是避免液體太過快速流動而產生氣泡。
When the
根據牛頓第二定律:F=ma,得知施力正比於物體的加速度。連通管路3的截面積為固定,因此壓力差正比於所產生的施力也正比於液體移動
的加速度。換句話說,壓力差所產生的加速度為可計算的。液體的流動速度為液體移動的加速度的時間函數。當逐步改變壓力差,液體的流動速度也會隨之變化。如圖6所示,藉由計算液體的流動速度與時間的積分並乘以連通管路3的截面積,進入第二儲存容器21的液體總體積就可以被精確地算出。
According to Newton's second law: F=ma, it is known that the applied force is proportional to the acceleration of the object. The cross-sectional area of the
綜上所述,本發明的液體傳輸設備100的液體傳輸路徑,不需要經過任何接頭或閥體,液體不會受到汙染。液體傳輸的總體積可以被精準地控制。除此之外,液體傳輸設備100內部充滿高氣壓,故液體的蒸氣壓很低,不會殘留於傳輸路徑中,也就不會影響下一次的液體傳輸。
To sum up, the liquid transmission path of the
進一步地,本發明的液體傳輸設備100於傳輸狀態下,第一儲存容器11的內部與第二儲存容器21的內部之間的壓力差滿足以下公式:P>ρ gh。其中P表示第一儲存容器11內部與第二儲存容器21內部之間的壓力差。ρ表示液體的密度,g表示重力加速度,h表示連通管路3的路徑最高點與液體輸出口112之間的高度差。
Further, in the transmission state of the
如圖7A所示,液體接收口213的高度高於液體輸出口112的高度。這表示連通管路3一定具有至少一個往上升的路徑。在圖7A中,連通管路3的路徑最高點與液體輸出口112之間的高度差為h1。這表示,即使液體傳輸設備100於非傳輸狀態下,只要第二儲存容器21內部與第一儲存容器11內部的壓力差小於ρ gh1,液體也無法通過連通管路3而進入第二儲存容器21。所以第二儲存容器21內部可以常態地保持略小於第一儲存容器11內部的氣壓。而只要第二儲存容器21內部的氣壓常態地保持等於或略大於第一儲存容器11內部的氣壓,就可以限制流體不進入連通管路3。另一方面,當液體傳輸設備100於傳輸狀態下,第二儲存容器21內部與第一儲存容器11內部之間的壓力差必須大於ρ
gh1(第二儲存容器21內部的氣壓小於第一儲存容器11內部的氣壓),以克服高度差帶來的影響。
As shown in FIG. 7A , the height of the
如圖7B所示,液體接收口213的高度約略等於液體輸出口112的高度。在圖7B中,若連通管路3沒有至少一個往上升的路徑(例如虛線的連通管路3a所示),則液體傳輸設備100於非傳輸狀態下,第二儲存容器21內部的氣壓必須大於第一儲存容器11內部的氣壓才能阻止第一儲存容器11內部的液體流入第二儲存容器21。然而當液體傳輸設備100於傳輸狀態下,只要一點點的壓力差就能驅動液體經由虛線的連通管路3a進入第二儲存容器21。若連通管路3具有至少一個往上升的路徑,在圖7B中連通管路3的路徑最高點與液體輸出口112之間的高度差為h2。液體傳輸設備100於非傳輸狀態下,只要第二儲存容器21內部與第一儲存容器11內部的壓力差小於ρ gh2,液體也無法通過連通管路3而進入第二儲存容器21。所以第二儲存容器21內部可以常態地保持略小於第一儲存容器11內部的氣壓。而只要第二儲存容器21內部的氣壓常態地保持等於或略大於第一儲存容器11內部的氣壓,就可以限制流體不進入連通管路3。另一方面,當液體傳輸設備100於傳輸狀態下,第二儲存容器21內部與第一儲存容器11內部之間的壓力差必須大於ρ gh2,以克服高度差帶來的影響。
As shown in FIG. 7B , the height of the
如圖7C所示,液體接收口213的高度低於液體輸出口112的高度,兩者的高度差為h4。在圖7C中,若連通管路3沒有至少一個往上升的路徑(例如虛線的連通管路3b所示),則液體傳輸設備100於非傳輸狀態下,第二儲存容器21內部與第一儲存容器11內部之間的氣壓差必須大於ρ gh4(第二儲存容器21內部的氣壓大於第一儲存容器11內部的氣壓),才能阻止第一儲存容器11內部的液體流入第二儲存容器21。反之,液體傳輸設備100於傳輸狀態
下,只要第二儲存容器21內部與第一儲存容器11內部之間的氣壓差低於ρ gh4,第一儲存容器11內部的液體很容易流入第二儲存容器21。若連通管路3具有至少一個往上升的路徑,在圖7C中連通管路3的路徑最高點與液體輸出口112之間的高度差為h3。其壓力控制的算法如同圖7B,不再贅述。
As shown in FIG. 7C , the height of the
綜上所述,本發明的液體傳輸設備100,可以依據液體接收口213與液體輸出口112的相對高度,搭配連通管路3的路徑設計,決定對於第二儲存容器21較適合的氣壓控制。
To sum up, the
進一步地,如圖1A及圖1D所示,輸出端裝置1更包括一排液構件13。排液構件13包括一排液管路131及一排液泵132。排液管路131連通第一儲存容器11的底部的一排液口113。排液泵132設置於排液管路131。第一儲存容器11剩餘的液體可經由排液構件13排除。在較佳的實施例中,排液口113設有一單向密封膜113a。單向密封膜113a兩側的壓力差大於一定程度才會開啟,使液體通過排液口113進入排液管路131。如圖1A所示,排液泵132未啟動,單向密封膜113a兩側無壓力差。再如圖1D所示,排液泵132啟動抽氣,使排液管路131的氣壓減小,因此單向密封膜113a開啟而使液體通過排液口113進入排液管路131。排液泵132可以為手動操控,也可以是訊號連接控制裝置4,經由控制裝置4命令排液泵132開啟。在其他的實施例中,排液構件13不具有排液泵132。藉由手動操控或控制裝置4命令第一加壓構件12及/或第二加壓構件221對第一儲存容器11加壓,迫使剩餘的液體通過單向密封膜113a進入排液管路131。
Further, as shown in FIG. 1A and FIG. 1D , the
進一步地,輸出端裝置1更包括一秤重構件14,訊號連接控制裝置4。控制裝置4依據秤重構件14量測的第一儲存容器11的重量變化,決定是否啟動排液泵132。
Further, the
進一步地,輸出端裝置1更包括一清潔構件15,設置於第一儲存容器11。清潔構件15包括清潔管路151及清潔閥152,清潔管路151可導入水、清潔液或其他潤洗液體至第一儲存容器11。這些導入的液體由排液構件13排除。清潔閥152設置於清潔管路151,控制液體的進入。清潔閥152可以為手動操控,也可以是訊號連接控制裝置4,經由控制裝置4命令清潔閥152啟動。清潔構件15可以具有多組的清潔管路151及清潔閥152,分別注入不同的水、清潔液或其他潤洗液體。
Further, the
進一步地,如圖1A所示,第二儲存容器21包括一固定蓋體211及一可拆卸瓶體212。連通管路3、氣壓調節構件22(包含第二加壓構件221及降壓管路222b)連接於固定蓋體211。可拆卸瓶體212可相對於固定蓋體211分離,而容易地取出液體。然而在其他例子中,第二儲存容器21設置可抽取液體的吸管,以吸取第二儲存容器21的液體。
Further, as shown in FIG. 1A , the
如圖2所示,在一個實施例中,多組輸出端裝置1及連通管路3分別連接到第二儲存容器21。多組輸出端裝置1及連通管路3分別傳輸不同的液體,被同一個第二儲存容器21接收。

如圖5所示,在一個實施例中,連通管路3包含一內管31與一外管32。液體於內管31流通,外管32包覆內管31。外管32可防止內管31內部的液體洩漏至液體傳輸設備100外部。
