技术领域
本发明涉及喷雾冷冻干燥技术领域，特别是涉及一种用于收集喷雾冷冻冰球颗粒的双密封式设备及其收集方法。
背景技术
喷雾冷冻干燥技术主要分为液滴冷冻成冰球和冰球干燥两个过程。具体地，上述两个过程可在同一设备内进行也可以在两个设备内分别进行。目前，实验室级别的小型喷雾冷冻干燥设备，能够实现冷冻和干燥两个过程在同一个设备内进行。然而，上述方法只适用于小型的间歇操作，不适于连续操作或者大中型设备。
想要实现连续操作须将收集的冰球转移入真空冷冻干燥设备内，而转移的过程通常会出现三个问题：

二、空气中的水分凝结在冰球表面导致冰球粘结；
三、冰球融化。
因此，针对上述问题，有必要提出进一步的解决方案。
发明内容
有鉴于此，本发明提供了一种用于收集喷雾冷冻冰球颗粒的双密封式设备及其收集方法，以克服现有技术中存在的不足。

图3为隔板插入相应的插槽的平面示意图。
具体实施方式
为了使本技术领域的人员更好地理解本发明中的技术方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
图1为本发明的用于收集喷雾冷冻冰球颗粒的双密封式设备的一具体实施方式的平面结构示意图；图2为图1中双密封式设备的俯视图。
结合图1、2所示，本发明的用于收集喷雾冷冻冰球颗粒的双密封式设备可被用于与冷冻塔相配合，实现冷冻塔内冰球的收集。具体地，所述收集装包括：收集器10、收集车20、抽真空装置30、加热装置40、第一密封垫50以及第二密封垫60。
所述收集器10位于所述收集车20上，所述收集器10具有收集口，通 过该收集口可使冷冻塔200内的冰球进入到收集器10内部。优选地，所述收集器10为锥形收集器。此外，为了便于收集车的更换，所述收集器10与所述收集车20之间通过可拆卸的方式进行连接。
进一步地，为了实现冰球的顺利收集，所述收集口与所述冷冻塔底部的出料口相对应，并可与所述出料口对齐。所述相对应是指所述收集口口径与所述出料口口径的尺寸相对应。此外，还要求本发明双密封式设备的高度与冷冻塔底部出料口距地面的高度相一致。所述收集车20的底部还设置有刹车轮21，从而，当所述收集口与所述出料口对齐时，可通过刹车轮21使得双密封式设备整体位置保持固定，避免收集口与所述出料口发生错位。
配合参照图3所示，所述出料口和收集口分别通过第一隔板11和第二隔板12进行打开或关闭。其中，所述第一隔板11和第二隔板12的一端具有把手，另一端具有斜面结构。从而，在隔板插入相应的插槽，以关闭相应开口时，注意保持斜面结构朝下设置，如此，便于保证相应开口的密封性。
所述第一密封垫50位于所述收集口处，所述第一密封垫50在所述收集口与出料口对齐时，可进一步形成二者之间的密封，防止热量的传递。同时，所述第二密封垫60位于所述收集器10的底部。从而，第一密封垫50和第二密封垫60共同形成了本发明收集设备的第一重密封结构。
同时，所述收集口处还设置有入水口13，所述入水口13与所述收集口与出料口对齐时形成的空间相连通。从而，当所述收集口和出料口对齐时，通过向入水口注入水，由于冷冻塔温度较低，从而，可在收集口和出料口之间形成冰密封，该冰密封形成了本发明收集设备的第二重密封结构。
从而，通过上述两种密封方式，有效保证了设备整体的密封性，避免了空气中的水分进入了冷冻室内造成冷冻室内壁结冰，以及空气中的水分凝结在冰球表面导致冰球粘结和融化的问题，实现了实现冷冻塔中冰球的顺利转移。
所述加热装置40位于所述收集口处，从而，当所述加热装置40开启时，加热装置40可向冰密封传递热量，使冰融化，以解除冰密封，将收集有冰球的双密封式设备推走。优选地，所述加热装置40包括加热圈。
所述抽真空装置30与所述收集器10的内部空间相连通，从而，当所述抽真空装置30开启时，可实现所述收集器10内部空间的抽真空，以进一步防止所述收集器10的内部空间与外界发生热量的传递。优选地，所述 抽真空装置30包括真空泵31和真空表32，其中，所述真空泵31与所述收集器10的内部空间相连通，所述真空表32可显示所述收集器10的内部空间的真空度。
此外，所述双密封式设备还包括温度计70，所述温度计70延伸至所述收集器10的内部空间中，以便测试所述收集器10内部空间的温度。
基于如上所述的用于收集喷雾冷冻冰球颗粒的双密封式设备，本发明还提供一种收集方法，其包括如下步骤：
S1、将双密封式设备推至冷冻塔的下方，使收集口与出料口对齐，并使收集车20保持位置固定；
S2、向入水口13注入水，使收集口与出料口之间形成冰密封；
S3、抽掉出料口处的第一隔板11，使冷冻塔中的冰球进入收集器10中；
S4、收集完成后，插入第二隔板12，关闭收集口，并打开抽真空装置30，对收集器10内部进行抽真空；
S5、插入第一隔板11，开启加热装置40，待形成冰密封的冰融化后，利用收集车20将双密封式设备推走；
S6、重复步骤S1～S5至冰球收集转移完成。
综上所述，本发明的用于收集喷雾冷冻冰球颗粒的双密封式设备能够克服现有技术中的缺陷，实现冷冻塔中冰球的顺利转移。其通过密封垫和冰密封的双密封方式，获得了较好的密封性，且可根据需要顺利更换使用的收集车，使用方便。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
