化学实验用细颈瓶清洗机的设计

Design of cleaning machine for chemical experiment

实验用细颈瓶是指那些在实验中使用的、瓶口相对较小的玻璃瓶,如在化学实验中经常用到的容量瓶、锥形瓶等。这类瓶很不容易清洗,不但增加了实验者的工作强度,而且降低了工作效率。因此,研制一种清洗这类瓶的清洗机具有十分重要的意义。实验用细颈瓶清洗机的设计在考虑到方便、实用的基础之上,对该类瓶的清洗方法以及清洗流程等各个方面进行了分析、总结,完成了对该清洗机清洗方法的选择、清洗流程的确定及总体布局的设计。设计运用Solid Work软件完成了对清洗机的总体设计;通过分析现有喷头的优缺点,设计了锥形螺旋缝隙式喷头,并用Excel分析设计了喷头的螺旋倾角;通过计算总体压力损失,完成了对泵体的选择;根据瓶体的大小和数量,确定了喷箱和洗涤液箱的尺寸参数。该清洗机冲洗效果好,使用方便,节省了冲洗时间,降低了劳动强度,并且将洗涤液回收、循环利用,节约了洗涤液资源,做到了环保。该清洗机不但可以在各个高校化学实验室和生物实验室广泛应用,还可以应用到医学实验以及其他化工厂的实验中。

The experimental narrow mouth flasks refers to the glass bottles used in chemistry experiment that. The cleaning of the bottle is not only increasing the working strength,but also reducing the working efficiency.Therefore,developing a cleaning machine for the bottles is extremely significant.This experimental flask cleaner＇s design carried out on the analysis and summary to this kind of bottle ＇s cleaning method as well as the cleaning procedure. The design plan,the cleaning method,the cleaning procedure,and the overall layout determined considering not only convenient,but also practical.The overall design angle of the nozzle was analyzed with Excel; based on computation on pressure loss,the pump was selected; the cleaning box and detergent box were designed according to the size and number of bottles. The machine ＇s washing effect is good,and it is easy to operate,meantime,it reduces the labor intensity. It can recycle the washing solution,save the detergentresources,protect the environmental.It can be used not only in each university chemical laboratory and the biological laboratory,but also in the medicine experiment,as well as in other chemical plant experiment.
