A scraper evaporator rotor assembly comprises a drive shaft and a plurality of scraper supports arranged on the drive shaft. Several scraper supports are connected to each other through a tie rod to form an integral structure. The tie rod is arranged at the end of one side of the scraper support. A positioning hole is arranged at the end of one side and a cemented carbide wear-resistant sleeve is arranged in the positioning hole. The wear-resistant sleeve is located between the positioning hole and the pull rod, and the pull rod is connected with multiple scraper supports through the wear-resistant sleeve. A fixed distance sleeve is arranged between the adjacent scraper supports, and the fixed distance sleeve is arranged on the pull rod. The two ends of the tie rod are threaded, and the two ends of the tie rod are locked and connected with a plurality of scraper supports through nuts. The utility model connects multiple scraper supports into a whole through a tie rod, increases the overall strength of the scraper support, and effectively prevents deformation after being stressed. Cemented carbide wear-resistant sleeve prevents the vibration of the rotor caused by the wear of the positioning hole. The fixed distance sleeve between the scraper supports can ensure that the distance between the scraper supports remains unchanged, the relative position of the scraper remains unchanged, and the film forming effect is ensured.

一种刮板蒸发器转子组件
本技术涉及一种属于蒸发器设备
,特别是涉及一种结构稳定,震动小,有效防止刮板脱落的刮板蒸发器转子组件。
技术介绍
刮板蒸发器的全名是机械搅拌式刮板蒸发器,又称为旋转式刮板蒸发器。是一种新型高效的节能降膜蒸发器。它以设备传热系数较高、物料停留时间较短、适用的粘度范围宽、操作的弹性大等优越的性能,在氯碱、化工、轻工、食品、制药和环保等行业得到广泛的应用。其工作原理如下:物料进入蒸发器后通过转子上刮板的搅动强制成膜,热源热量经筒壁与料液进行热交换,液膜沸腾,二次蒸汽汽化后经过捕膜器除去夹带的液滴后排出,浓缩液由底部出料口放出。现有的刮板蒸发器转子组件结构为组成包括电机驱动转动的的传动轴,传动轴上设置有多个刮板支撑,刮板连接在刮板支撑端部。由于多个刮板支撑之间相互独立,且长期在高温状态下使用。长期工作后会造成形变,导致转子震动,不能有效地工作,甚至导致刮板的脱落,从而影响刮板成膜的效果。
技术实现思路
本技术目的在于针对现有的刮板蒸发器转子组件存在的缺陷,提供一种结构稳定,不易发生形变,震动小,有效防止刮板脱落的刮板蒸发器转子组件。本技术为实现上述目的,采用如下技术方案:一种刮板蒸发器转子组件,包括电机驱动转动的传动轴和设置在所述传动轴上的多个刮板支撑,其特征在于:多个所述刮板支撑通过拉杆相互连接成一体结构。其进一步特征在于:所述拉杆设置在所述刮板支撑安装刮板的一侧端部。进一步的:所述刮板支撑的一侧端部设置有定位孔,所述拉杆穿过所述定位孔连接多个所述刮板支撑。优选的:所述刮板支撑的定位孔内设置有耐磨套,所述耐磨套位于所述定位孔和拉杆之间。 ...
