干冰清洗機的行走系統(tǒng)
專業(yè)班級：06機制14班 學生姓名：張志勇
指導教師：梁 博 職 稱： 講 師
摘 要 本設計論述了研制自動化連續(xù)型干冰清洗機的必要性和可行性。干冰可以分為葉狀類干冰和根莖類干冰，葉類干冰表面殘存有塵土、有機肥、及殘存的化學農(nóng)藥、微生物等，且葉類干冰本身比較嫩脆，容易折段壓潰，而根莖類干冰表皮強度較好，有的還要求去皮食用，不存在表皮損傷問題。我們針對葉狀類類干冰和根莖類類干冰這兩種干冰物理性質(zhì)的不同，分別設計了QX-J型根莖類干冰清洗機和QX-Y型葉狀類干冰清洗機，并介紹了其工藝流程和整體結(jié)構(gòu)。QXJ型根莖類干冰清洗機采用滾筒方式清洗，QX-Y型葉狀類干冰清洗機的工藝流程為浸泡清洗 -- 噴射清洗 -- 超聲波清洗 -- 噴淋清洗 -- 出菜。
利用高于20KHZ的超音頻電能的超聲波，能通過換能器轉(zhuǎn)換成高頻機械振蕩而傳入到清洗液中。超聲波在清洗液中疏密地向前輻射，使液體移動，并產(chǎn)生數(shù)萬計的微小氣泡，這些氣泡在超聲波縱向傳播的負壓區(qū)形成、生產(chǎn)、迅速閉合稱為空化現(xiàn)象。在空化現(xiàn)象中氣泡閉合時形成超過1000個大氣壓的瞬時高壓，連續(xù)不斷產(chǎn)生的瞬時高壓就像一連串小爆炸不斷地轟擊物體表面，使物體表面及縫隙中污垢迅速剝落，這種空化侵蝕作用就是超聲波清洗的基本原理。

The washing and spraying type machine for vegetable
Abstract This design expounds the necessity and feasibilities to develop the automation continuous type wash, vegetables are divided into leaf form type vegetables and rhizome type vegetable. The surface of the leaf type vegetables and rhizome type vegetable. The surface of the leaf type vegetables remains to have dust, orangic fat. Chomical agriculture chemical and microorganism. And it is fresh and flat, getting easy to be rolled over .The epidermis of the rhizomes type vegetables intensity better. More of them require to unskin eating. So it does not exist the epidermis problem of damaging, we directed against the differences of physical properties of leaf form type vegetables and rhizome type vegetables to design model QX-J wash for leaf form type vegetables and QX-Y for rhizome type vegetables and introduces their technological process and whole structure. Model QX-J rhizome type vegetables wash machine adopt cylinder. And the processes of the Model QX-Y leaf form type wash machine is immersion washing—spray washing—ultrasonic wave washing—spray washing—bringing 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 the intermedium.Nonstopped vibration of ultrasonic made the liquid moved forward in the intermedium and can give birth to ten thousands 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 to dense explosion on the surface of cleaned object made the grease stain fabled off. The fun dametal is the theory of ultrasonic cleaning.
