2、。 利用高于 20KHZ 的超音频电能的超声波,能通过换能器转换成高频机械振荡而传 入到清洗液中。超声波在清洗液中疏密地向前辐射,使液体移动,并产生数万计的微 小气泡,这些气泡在超声波纵向传播的负压区形成、生产、迅速闭合称为空化现象。 在空化现象中气泡闭合时形成超过 1000 个大气压的瞬时高压, 连续不断产生的瞬时高 压就像一连串小爆炸不断地轰击物体表面,使物体表面及缝隙中污垢迅速剥落,这种 空化侵蚀作用就是超声波清洗的基本原理。 关键词 自动化 浸泡 喷淋 超声波清洗 水处理 毕业论文 - 3 - 毕业论文外文摘要毕业论文外文摘要 The Design Study about The 6S
3、X-320-type washing Machine for Vegetable Abstract This article discusses the development of automated continuous washing machine leafy vegetables need and feasibility. The surface of the leaf type vegetables remains to have dust, orangic fat. Chomical agriculture chemical and microorganism. And it i

We focused on the characteristics of phyllodes vegetables designed 6SX-320-type leaf-like vegetable washing machine, and presented the overall structure of the process. Model 6SX-320 rhizome type vegetables wash machine adopt cylinder. And the proce
5、sses of the Model 6SX-320 leaf form type wash machine is immersion washingspray washingultrasonic wave washingbringing the vegetables out. The height frequently effect ultrasonies which are more than 20 KHZ are translates the mechanical vibrational via the exchanged energy organ and transmitted into
6、 the intermedium.Nonstopped vibration of ultrasonic made the liquid moved forward in the intermedium and can give birth to ten thousands 6SX-320 型叶菜清洗机的设计研究 - 4 - of little air bubble. It is called for around-the-clock that the air bubbles form, develop and shut up rapidly in the pressure region of the track of the ultrasonic moving. The opening of the air bubbles form one thousand of air pressure. The lash of the surface of cleaned object continuous and continuous which likes giving birth
