水磨粉雙滾筒干燥機總體設計及傳動裝置設計
摘 要:為解決小型水磨粉生產企業(yè)水磨粉干燥問題,設計雙滾筒干燥機代替噴霧干燥,從而減少熱量損失,提高效率。使之能夠滿足相關工業(yè)的發(fā)展要求。
滾筒干燥機是一種內加熱傳導型轉動連續(xù)干燥設備。該課題主要設計內容包括水磨粉雙滾筒干燥機總體設計及傳動裝置設計,可分為四方面:1)制定總體方案,確定滾筒配置型式及結構方案;2)滾筒組件設計的有關計算、校核等;3)傳動裝置設計的有關計算、校核等;4)完成動力設計、運動設計、結構設計、熱工計算。
本課題考慮機器的結構緊湊,首先確定了各級傳動型式,其次應用現(xiàn)代CAD技術選定傳動零件,設計非標準件和設備總體結構。運用AutoCAD繪制設備的總裝配圖、各個零件的零件圖和傳動路線圖,以指導各零件的加工和設備的設計,以此保證該設備運動平穩(wěn),操作簡便,便于維修和調試,操作彈性大,適用性廣,熱效率高,干燥時間短。

The Design of the Overall and Transmission Device of Water Mill Double-Drum Dryer
Abstract:In order to solve water mills-dry problem of small water mill production enterprises, we design double-drum dryer which replaces spray drying, and reduce heat-loss and improve efficiency. Enable it to meet modern industrial development.
Drum dryer is a heat-conduction within the rotation for drying equipment. The main design elements of this device include the designs of water mills double-drum dryer and transmission device .Design includes four aspects: First, design the overall program and determine the allocation of drum patterns and structure. Second, design of drum components involves calculations, Check and so on .Third, design of transmission device involves calculations, Check and so on. Fourth, complete dynamic design, moving design, structural design, and thermal calculation.
Compact structure of the machinery was considered the design, above of all, determine Drive-level set pattern, then select transmission parts, design non-standard equipments and devise overall structure by use of modern CAD technology. Using AutoCAD to draw the total equipment assembly, maps of various parts and drive components roads, which can guide the processing of components and designing of equipment. These can ensure the smooth movement of equipment, easy to operate, easy to maintenance and debugging, operating flexibility, broad applicability, high thermal efficiency, and short drying time.
