Description
本发明涉及一种粉末脱脂剂、其制备方法及干燥装置。
在工业生产中，需要用到多种油脂组成的乳化液对产品进行润滑和冷却，因此，这种油脂润滑剂在产品完成后在其表面回头残留，在对产品退火前，必须通过化学脱脂和电解脱脂的方法将这层油污去除；以防止这层油污退火时在钢板表面碳化而出现渗碳现象和形成碳质污斑，影响产品在后工艺进行涂镀或其它加工处理时的性能和质量。现在市场上销售的大量脱脂剂碱度低、泡沫大，不但造成清洗不彻底的问题，钢厂使用时脱脂剂的消耗量也大，而且需要额外投加消泡剂，这就大幅增加了现场工人的劳动强度，清洗成本也随之上升。

在一实施例中，如图4所示，第一搅拌机构4包括电机41、旋转轴42和叶片43，旋转轴42转动设置在主罐体1内，叶片43环绕设置在旋转轴42周向，电机41设置在主罐体1的顶部，利用电机1驱动旋转轴42以带动叶片43转动。进而对主罐体1内的溶液进行混料。
在一实施例中，如图5所示，第二搅拌机构包括空气压缩机和进气管5，进气管5设置在子罐体2底部，并且与空气压缩机连接，进气管具有若干个气孔，利用空气压缩机将气体送入进气管，从气孔将气体排出。在溶液中产生气泡，利用气泡对溶液进行搅拌。另外，由于子罐体2为密闭容器，由第二搅拌机构通入的气体始终储存于子罐体2内，子罐体2内的压力不断增加，当出液口的阀门打开后，利用子罐体2内的压力将溶液排出；当子罐体2内压力不足时，通过进气孔211进行压力补充，以保证后续溶液正常排出。
在一实施例中，如图6-11所示，第三搅拌机构6包括壳体61、安装块62和混料管63，壳体61内设置安装安装块62的安装腔611，安装块62上设置若干个贯穿的安装管621，混料管63设置在安装管621内，壳体61的两端分别设置进液口与出液口。通过水泵3将溶液从进液口打入混料管63内，通过混料管对溶液混料后从出液口排出，经管路引导回入主罐体1内。其中，混料管63包括管体631和若干个叠加的搅拌单元632，搅拌单元632呈螺旋状，一搅拌单元632的下端与另一搅拌单元632的上端相互垂直。可见，一搅拌单元632将溶液分切旋转后通过下一个交班单元632再分切，进而实现对溶液的混料。壳体61包括外壳612、密封条613和外盖614，安装腔611凹设在所述外壳612内，外壳612上表面绕安装腔611周边凹设密封槽615，在并且在外盖614得对应位置与密封槽615配合的密封凸缘616，密封条613设置在密封槽内，

在一实施例中，如图6-11所示，为了方便将主罐体1内搅拌完毕的液体排出，第三搅拌机构6的出液端连接三通阀门64，三通阀门64的一端与主罐体1连接，另一端为排液口65。当搅拌时，三通阀门64连接第三搅拌机构6和主罐体1；当排料时，三通阀门64连接第三搅拌机构6和排液口65，通过水泵3将主罐体1内的液体抽出通过第三搅拌机构6从排液口65排出。
在一实施例中，如图12所示，还包括进液管7，进液管7包括主管71和轴向排列在71的子管72；主管71上设置进液口，子管72上设置出液口。进液管7的进液口与三通阀门64连接，出液口与主罐体1连接，并且进液方向与主罐体1相切。主罐体1内的液体通过第一搅拌机构4进行顺时针搅拌，使得溶液顺时针流动，而从出液口排出的溶液顺着主罐体1的内壁逆时针流动，两股溶液相互撞击，提高溶液混料效率。

在一实施例中，如图13-15所示，驱动机构93包括电机931和凸轮932，干燥罐91底部一侧通过转轴与底座92转动连接，在另一侧转动设置凸轮932，利用电机931驱动凸轮932转动。当凸轮932旋转至长直径竖直设置时，干燥罐91倾斜15°，使得干燥罐91内部的干燥物从开口去取出。当凸轮932端直径竖直设置时，干燥罐91水平放置。优选的，使干燥罐91工作时更加稳定，底座上设置若干个垫块，以支撑干燥罐91，并且减少凸轮932的负载。
在一实施例中，如图13-15所示，干燥罐91侧壁设置中空隔热层99。以减少热量散失。
