轉筒干燥器的總體與結構設計
學生姓名：曾傳林 班級：0681053
指導老師：張曉榮
摘要：在化學生產中，有些原料、半成品或成品含有或多或少的水分或其他溶劑。為了滿足使用的要求，常采用干燥的方法將這些水分或溶劑除去，而干燥的方法和設備是多種多樣的。
回轉干燥器是一種常見的干燥設備。它適合于顆粒狀、濕物料的干燥，如純堿、硝銨、和各種鹽類等。回轉干燥器能使物料在滾桶內翻動、拋撒、與熱空氣或煙道氣充分接觸，干燥速度快，生產力較高，因此廣泛應用于化工、食品等工業(yè)生產中。
設計的主體部件是1000×8000mm規(guī)格的轉筒部分,筒的轉動依靠齒輪帶動,筒的重量主要由兩個托輪支撐,而托輪則由兩個軸承支撐,抄板翻動物料。
該設備生產能力大、結構簡單，但是效率較低。
關鍵詞：回轉 托輪 齒輪 軸承 抄板

ROTARY DRYER WITH THE STRUCTURAL DESIGN OF THE OVERALL
Student Name: Zeng Chuanlin Class: 068153
Supervisor: Zhang Xiaorong
Abstract: In the processing of the chemistry industry, some materials、semi-finished produces or finished produces, contain more or less imprecision or other solvents．In order to satisfy the use requests, we need rid them by drying technical. And the methods of drying and equipments are varied．
The drying machine of turning around、cylinder is an old、usual equipment .It is fit to dry the wet materials ,such as sulphur 、all kinds of salts etc .It can make the materials turning over、throwing or scattering , and contact with the hot air amply .It’s drying speed is faster, and the manufacture ability is also very good .So it applies to the processing of the chemistry 、foodstuff etc widely.
The assignment of the design is the turning around section of serial 1000×8000mm .The turning of tubeshaped object depends on the gears .The weight is sustained with two supporting wheels .The supporting wheels is sustained with two bearing .The funtion of lifting of board is to turn over the matters.
The manufacture ability of this equipment is larger ,and the structure is simple ,but the efficiency is very lower.
Keywords: turning around ,supporting wheels ,the gears ,bearing ,lifting board .
