Abstract
本发明公开一种新型润滑油调和釜。通过在进料口前连接一种增粘剂储存罐加热保温装置的设计,从而降低增粘剂粘度,使增粘剂可以通过气压泵作用从进料口进入反应釜,且储存罐中始终保持氮气氛围,能够保护增粘剂不被氧化。另外用过对搅拌器的改良,在搅拌叶上均匀添加有加热片,使设备搅拌更加均匀,残留物更易清理,减少了人工操作,提高运作效率。
Description
技术领域
本发明属于一种化工设备领域技术领域,具体涉及一种润滑油调和釜。
背景技术
润滑油作为汽车行业、机械设备以及金属加工中的润滑剂,广泛应用于各行各业。润滑油一般由基础油和添加剂两部分组成,常用的基础油包括矿物油、合成油、生物油等;常用的添加剂包括增粘剂、油性剂、极压添加剂、粘度指数改进剂、防锈剂、抗氧化剂等。润滑油的生产主要是将基础油和添加剂混合加入调和反应釜中,再经过搅拌加热的方式混合均匀,最后得到成品的润滑油。
但是根据设备、作业环境的不同,对润滑油的粘度需求有所差异,润滑油的生产常常需要添加增粘剂来增加油品的粘度,常用的增粘剂的在常温情况下,粘度高达几万cP。通常情况下,粘度高的增粘剂在生产过程中不能直接使用气压泵通过进料口进入反应釜,从而只能停止设备运作,打开反应釜,通过人工加料的方式导入。这样工厂生产中工作人员劳动强度的增加,生产效率降低。
由此可见,现有的润滑油生产装置不能满足产线自动化的需求,无法动过自动机械的方法进行添加增粘剂,使生产效率得不到有效的提升。
发明内容
为解决上述技术问题,本发明提供了一种润滑油调和釜,解决了润滑油生产时添加增粘剂困难的技术问题,且这种调和釜具有结构简单、操作方便、生产高效的特点
本次发明为达到上述目的所采用的技术方案是:
一种润滑油调和釜,包括釜体、储存罐,所述釜体包括顶盖、搅拌装置、混合腔,所述顶盖与混合腔是分离的,通过锁扣装置紧密闭合;所述搅拌装置嵌于顶盖中部;所述混合腔下端右侧设有出料管,上端左侧设有进料管,进料管连接着储存罐,进料管中部有计量泵,使储存罐中液体能通过进料管进入混合腔。所述储存罐包括罐盖,罐内腔、加热管、保温棉,氮气进气口、氮气出气口,所述罐盖与罐内腔是分离的,通过锁扣装置紧密闭合;所述储存罐的外壁与罐内腔之间存在空腔,所述加热管设置在罐内腔与储存罐外壁之间的空腔内,所述储存罐的外壁包裹有一层保温棉;所述储存罐左侧上部有氮气进气口,右侧上部有氮气出气口。
优选的,所述搅拌装置嵌于顶盖中部,上端为加热器及搅拌驱动电机,下端由一传动连接杆连结搅拌叶,搅拌叶上均匀嵌有加热片。
优选的,所述搅拌装置的搅拌叶片,垂直水平分布三层,每层结构相同,均为水平分布具有一定厚度三叶片形状。
优选的,所述储存罐左侧上部有氮气进气口,其罐外导管连接氮气泵,罐内导管延伸至罐内底部。
优选的,所述计量泵具有定量控制流体通过的功能。
优选的,所述储存罐与釜体为连通体系。
与现有技术相比,本发明的有益效果在于:
本发明通过在调和釜进料口设置有增粘剂储存罐,储存罐通过空腔加热片的加热作用,以及外层保温棉的保温作用,对增粘剂起到保温加热的效果,使其粘度降低,在气压泵的作用下,增粘剂能够自动流向进料口,从而通过进料导管进入调和釜。通过将加热片嵌于搅拌装置的每块搅拌叶片中,恒温温度与储存罐中环境温度相同,使得调和釜中增粘剂的粘度保持降低,易于搅拌,使得调和油搅拌充分均匀,损耗能量降低。另外通过氮气泵的作用,使调和釜和储存罐始终处于充满氮气的状态,最大限度的保证增粘剂及基础物料不被氧化,从而保证润滑油产品的质量。
