Q3110滾筒式拋丸清理機的設計
(總裝、彈丸分離裝置及集塵器設計)
摘要： Q3110滾筒式拋丸清理機的工作原理是利用高速回轉(zhuǎn)的葉輪將彈丸拋向滾筒內(nèi)的鑄件，以清除鍛件表面的殘余型砂或氧化鐵皮。
首先，對Q3110清理機的發(fā)展前景進行了預測和分析，證明了設計的可行性。其次，對Q3110清理機進行了總體方案的論證和選擇。然后對清理機的主要部件除塵器進行了具體的設計和分析。
概括地說，利用帶輪減速傳動和齒輪減速傳動帶動滾筒和提升斗的回轉(zhuǎn)，從而實現(xiàn)了彈丸的循環(huán)使用；另外，運用干式旋風型除塵裝置進行塵丸分離工作；彈丸循環(huán)裝置由滾筒護板與殼體間的螺旋帶提升機構(gòu)及分離篩組成。
設計的重點是除塵器的分析與計算，包括風機的選擇，葉輪的設計計算，葉輪軸的強度校核等。
總體設計主要針對小批量零件的清理工作，具有較好的使用價值和經(jīng)濟效益。

The Design of the Q3110 shot Blast cleaning Machine (The Design of the General Fitting、The pill recycling and separate system and the duster)
Abstract： The work principle of the Q3110 shot blast cleaning machine, is that the pill is cased into the casting in roller by the high speed rotation impeller, to clean remnant mounding sands or oxidizing sheet iron on the surface of the casting
Firstly, the development of the Q3110 cleaning machine is anticipated and analyzed and the feasibility of the design is guaranteed.
Secondly, the general design is demonstrated and selected. then one of main parts of the cleaning machine –duster is designed and analyzed。
To sum up, the rotation of the roller and the lifting machine by sprocket-down.. And the circulation use of the pill is realized. The shot motion is realized by gearing down. In addition, the dry rotary duster is used to separate pill from dust. And the pill circulating device is made up of the screw elevator machine and the separating griddle.
The emphases of the design is the analyse and calculation of the duster. It includes the selection and adjustment of the pneumatic conveyer, the design and calculation of the impeller, and the strength adjustment of the impeller.
As a whole, the design aims mainly at the cleaning of the smaller accessory. So the design has preferable value in practice and better benefit in economy.
