Description

一种具有自清洁结构的蒸发结晶装置 技术领域
本发明涉及蒸发结晶技术领域，尤其涉及一种具有自清洁结构的蒸发结晶装置。
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的过程，加热蒸发溶剂，使溶液由不饱和变为饱和，继续蒸发，过剩的溶质就会呈晶体析出，叫蒸发结晶，例如当NaCl和KNO3的混合物中NaCl多而KNO3少时，即可采用此法，先分离出NaCl，再分离出KNO3。
现在蒸发结晶在工业生产化学物质时受到广泛的应用，然而现有的蒸发结晶装置在使用时出现了以下的一些缺陷，首先，蒸发过程中蒸发装置内表壁会逐渐出现结块，影响结晶效果；其次，结晶后的蒸发装置内部会凝结大量固体，需要将内部的晶体除去。
发明内容
本发明的目的在于：为了解决蒸发时的结晶和蒸发后的晶体去除的问题，而提出的一种具有自清洁结构的蒸发结晶装置。
为了实现上述目的，本发明采用了如下技术方案：

作为上述技术方案的进一步描述：
所述第一滑槽共开设有两个，且两个第一滑槽关于第一传动杆中心轴对称，所述螺旋槽共开设有四个，其中顶部的两个螺旋槽与底部的两个螺旋槽关于第一滑块中心水平面对称。
作为上述技术方案的进一步描述：
所述第一滑块远离第一传动杆的一侧焊接有限位杆，且限位杆远离第一滑块的一侧开设有第一卡槽，且第一卡槽内部套设有第二传动杆。
作为上述技术方案的进一步描述：
所述L形支杆的竖直截面呈L形结构，所述L形支杆竖直杆内腔开设有第二卡槽，且第二卡槽与第二传动杆套接。
作为上述技术方案的进一步描述：
所述第二传动杆侧表壁焊接有卡环，且卡环与限位杆上下端面卡接，所述第二传动杆两个顶端均焊接有螺纹刀头，所述螺纹刀头与弧形板内腔套接。
作为上述技术方案的进一步描述：
所述壳体下端面中心轴处开设有出料口，所述壳体底部开设有入料口。
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，由于采用了第一滑块与第一滑槽之间的滑动连接，实现了对于第一滑块的伸缩，又由于采用了压缩弹簧对于第一滑块和第一传动杆的弹性连接，实现了将第一滑块推动到壳体侧表壁的方向，同时由于采用了弧形板下端面与L形支杆之间的焊接，实现了将弧形板压到壳体侧表壁对于蒸发结晶时的液体 进行搅动，同时对壳体侧表壁进行刮擦减少结块。
2、本发明中，由于采用了螺旋槽与弧形滑块之间的滑动连接，实现了第一传动杆转动带动弧形滑块运动到螺旋槽顶端，又由于采用了L形支杆与弧形滑块之间的焊接，实现了两个L形支杆的互相远离，同时由于采用了第二传动杆上下端面与螺纹刀头之间的焊接，实现了将螺纹刀头收到弧形板内部，避免螺纹刀头损伤壳体内表壁。
3、本发明中，由于采用了伺服电机的反向转动，实现了通过第一传动杆带动第一滑块的反向转动，又由于采用了螺旋槽与弧形滑块之间的滑动连接，实现了弧形滑块的反向滑动，从而使得两个L形支杆的互相靠近，同时由于采用了第一卡槽与卡环之间的卡接，实现了对于弧形板将螺纹刀头脱离出来，使得螺纹刀头对于壳体侧表壁蒸发后的结晶进行切割，方便壳体内部的自清洁。

请参阅图1-3，本发明提供一种技术方案：一种具有自清洁结构的蒸发结晶装置，包括壳体1以及壳体1上端面焊接的固定腔2，固定腔2内腔上端面焊接有伺服电机3，且伺服电机3输出轴处焊接有第一传动杆4，壳体1下端面焊接有底座11，第一传动杆4底部侧表壁开设有第一滑槽13，且第一滑槽13内部滑动连接有第一滑块9，第一滑块9通过压缩弹簧10与第一传动杆4弹性连接，第一滑块9内部开设有螺旋槽18，且螺旋槽18内部滑动连接有弧形滑块19，且弧形滑块19远离第一传动杆4的一侧焊接有L形支杆7，L形支杆7上端面焊接有弧形板6，使得L形支杆7的上下滑动带动弧形板6上下滑动，将螺纹刀头5释放出来或者收纳起来。
具体的，如图3所示，第一滑槽13共开设有两个，且两个第一滑槽13关于第一传动杆4中心轴对称，螺旋槽18共开设有四个，其中顶部的两个螺旋槽18与底部的两个螺旋槽18关于第一滑块9中心水平面对称，使得两个弧形板6顶部壳体1内腔两侧，避免第一传动杆4受到挤压变形影响转动。
具体的，如图1所示，第一滑块9远离第一传动杆4的一侧焊接有限位杆14，且限位杆14远离第一滑块9的一侧开设有第一卡槽15，且第一卡槽15内部套设有第二传动杆17，使得限位杆14固定住两个螺纹刀头5之间的距离，方便螺纹 刀头5的收纳和伸出。
具体的，如图1所示，L形支杆7的竖直截面呈L形结构，L形支杆7竖直杆内腔开设有第二卡槽16，且第二卡槽16与第二传动杆17套接，使得第二传动杆17始终被卡住，避免两个螺纹刀头5上下移动。
具体的，如图1所示，第二传动杆17侧表壁焊接有卡环8，且卡环8与限位杆14上下端面卡接，第二传动杆17两个顶端均焊接有螺纹刀头5，螺纹刀头5与弧形板6内腔套接，使得弧形板6对于螺纹刀头5进行收纳，避免螺纹刀头5直接刮擦壳体1内壁。
具体的，如图1所示，壳体1下端面中心轴处开设有出料口12，壳体1底部开设有入料口20，方便壳体1的上料和出料。
工作原理：使用时，首先，打开伺服电机3，使得伺服电机3带动第一传动杆4转动，此时壳体1受到外界加热使得壳体1内部的结晶液体逐渐蒸发，通过第一滑块9与第一滑槽13之间的滑动连接，使得第一滑块9在第一滑槽13内部滑动，同时通过压缩弹簧10对于第一滑块9与第一传动杆4之间的弹性连接，使得第一滑块9通过L形支杆7将弧形板6压在壳体1的内表壁，方便搅动壳体1内部的液体，减少壳体1侧表壁得到结晶结块现象；其次，通过螺旋槽18与弧形滑块19之间的滑动连接，使得第一传动杆4带动弧形滑块19滑动到螺旋槽18顶端，此时弧形滑块19之间的距离逐渐增加，使得L形支杆7之间的距离逐渐减小，从而使得两个靠近的弧形板6之间的距离增加，通过第二传动杆17上下两侧与螺纹刀头5之间的焊接，使得螺纹刀头5被收到弧形板6内部，避免螺纹刀头5直接与壳体1内腔长时间摩擦造成损坏；最后，结晶完成后，使伺服电机3反向转动，通过第一传动杆4带动第一滑块9反向转动，此时弧形滑块19滑动 到螺旋槽18另一端，使得弧形滑块19之间的距离减小，从而使得L形支杆7之间的距离逐渐减小，通过第一卡槽15内部转动连接的第二传动杆17支撑两个螺纹刀头5的距离不变，从而使得两个螺纹刀头5从弧形板6内部伸出，此时螺纹刀头5顶在壳体1内表壁的晶体上转动，使得壳体1内表壁的晶体被切割，方便壳体1的自清洁。
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。
