Description

一种高效蒸发结晶装置 技术领域
本发明涉及工业生产技术领域，尤其涉及一种高效蒸发结晶装置。
背景技术
蒸发是指将溶液中的溶剂通过升温的方式让溶剂脱离溶质的过程；结晶是溶质聚合变为固体(晶体)的过程。
然而现有的蒸发结晶装置在进行工作时仍然存在不足之处；现有的阵法结晶装置大多采用局部受热的方式进行加热处理，并在加热时进行搅拌，由于受热面积有限，导致结晶的效率较低。
发明内容
本发明的目的在于：为了解决现有蒸发结晶装置结晶效率较低的问题，而提出的一种高效蒸发结晶装置。
为了实现上述目的，本发明采用了如下技术方案：
一种高效蒸发结晶装置，包括结晶筒和加热器，所述结晶筒的中心位置处开设有积液筒，所述积液筒的中心位置转动连接有转动辊，且转动辊的外壁绕设有螺旋片，并且螺旋片远离转动辊的一侧顶部焊接有增高片，所述加热器嵌设于转动辊的内部，所述增高片靠近转动辊顶端的部分开设有豁口，所述结晶筒的内部开设有导水槽，且导水槽的两端均分别与积液筒的顶端和底端连通。
作为上述技术方案的进一步描述：
所述结晶筒的顶部设置有驱动电机，且驱动电机的输出轴与转动辊的顶部传动连接。
作为上述技术方案的进一步描述：
所述导水槽与积液筒连通的部分宽度与豁口的径向高度相等，所述增高片与积液筒的内壁贴合。
作为上述技术方案的进一步描述：
所述结晶筒的底端内部中心处焊接有集气冷凝槽，且集气冷凝槽的顶部与转动辊的底部转动连接。
作为上述技术方案的进一步描述：
所述积液筒的顶部开设有集气槽，且集气槽的水平截面呈环形，并且集气槽通过导气管与集气冷凝槽连通。
作为上述技术方案的进一步描述：
所述结晶筒的顶部和底部均焊接有连接柱。
综上所述，由于采用了上述技术方案，本发明的有益效果是：
1、本发明中，通过转动辊的转动方向和螺旋片的设置方向相反，使得溶液会在螺旋片上进行向上的运动，由于增高片高度有限，传输的溶液量有限，使得较小体积的溶液与转动辊的外部进行接触，提高蒸发的效率，加速结晶的形成，使得结晶更加的高效。
2、本发明中，通过螺旋片进行对溶液的搅拌，通过集气槽对蒸汽的利用，并将其用于溶液的保温，通过集气冷凝槽将蒸汽进行液化利用，提升了装置的效益，使得装置对能源的利用更加充分。

1、结晶筒；2、转动辊；3、螺旋片；4、增高片；5、豁口；6、集气冷凝槽；7、集气槽；8、导气管；9、导水槽；10、驱动电机；11、连接柱；12、加热器；13、积液筒。
具体实施方式
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作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
请参阅图1-3，本发明提供一种技术方案：一种高效蒸发结晶装置，包括结晶筒1和加热器12，结晶筒1的中心位置处开设有积液筒13，积液筒13的中心位置转动连接有转动辊2，且转动辊2的外壁绕设有螺旋片3，螺旋片3螺旋方向与驱动电机10的转动反向相反，并且螺旋片3远离转动辊2的一侧顶部焊接有增高片4，使得螺旋片3的顶部可以存住一定量的溶液，但体积有限，加热器12嵌设于转动辊2的内部，增高片4靠近转动辊2顶端的部分开设有豁口5，便于顶部的溶液回流，结晶筒1的内部开设有导水槽9，且导水槽9的两端均分别与积液筒13的顶端和底端连通。
具体的，如图1所示，结晶筒1的顶部设置有驱动电机10，且驱动电机10的输出轴与转动辊2的顶部传动连接，用于对转动辊2的驱动。
具体的，如图1所示，导水槽9与积液筒13连通的部分宽度与豁口5的径向高度相等，增高片4与积液筒13的内壁贴合，使得豁口5流出的溶液可以进入导水槽9的内部。
具体的，如图1和图2所示，结晶筒1的底端内部中心处焊接有集气冷凝槽6，且集气冷凝槽6的顶部与转动辊2的底部转动连接，积液筒13的顶部开设有集气槽7，且集气槽7的水平截面呈环形，并且集气槽7通过导气管8与集气冷凝槽6连通，用于对蒸汽的回收利用。
具体的，如图1所示，结晶筒1的顶部和底部均焊接有连接柱11，便于与其他装置的连接。
工作原理：使用时，在需要对积液筒13内部溶液进行蒸发结晶处理时，启动内部的加热器12进行工作，并且同时启动顶部的驱动电机10进行运转，此时驱动电机10的输出轴与转动辊2传动连接，使得转动辊2进行转动，在转动辊2转动时，其侧壁焊接的螺旋片3和增高片4同时进行转动，使得位于底部的溶液会进行与转动方向相反的运动，进而使得溶液在螺旋片3上进行向上的运动，对溶液进行抬升，由于增高片4的高度限制，使得抬升溶液体积有限，更好的与转动辊2进行接触，进而更好的进行蒸发作用，提升蒸发效率，抬升后未蒸发完全的溶液由豁口5漏出进入导水槽9中，流至转动辊2的底部进行新一轮的抬升，在螺旋片3进行转动的过程中对螺旋片3进行了对于溶液的搅拌作用，进一步加速结晶，在蒸发的过程中，产生的水蒸气进入顶部的集气槽7中，并通过导气槽流至集气冷凝槽6的内部，蒸汽在导气管8中流动时对导水槽9中的溶液进行保温作用，减少溶液的冷却程度的同时，提升对蒸汽的利用，流入集气冷凝槽6中的蒸汽液化，作为蒸馏水做其他用途，提升装置的经济效益。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之 内。
