分段式熱風(fēng)干燥設(shè)備的三維設(shè)計畢業(yè)論文(更新版)
【正文】 烘房里的水蒸氣；最后干燥的粉絲由傳輸帶運到出料段，這樣我們就能提高粉絲的烘干效率。Pw按下式進(jìn)行計算：式中，F(xiàn)為主動軸的工作阻力，N；v為主動軸的線速度，m/s。根據(jù)電機功率，平帶選用普通平帶，帶寬為32mm；帶輪寬為40mm； 查表得: 電機額定轉(zhuǎn)速w=720 r/min；額定功率為4kw； 主動軸和從動軸的設(shè)計計算 由電機的額定功率可知主動軸的承受的載荷功率 因為主動軸的最小直徑 所以代入數(shù)據(jù)得；又因為軸承是標(biāo)準(zhǔn)件，根據(jù)軸承的型號，確定=45mm；所以主動軸的尺寸如圖2：圖2所以從動軸尺寸如圖3：圖3 其它傳動件的選用因為平帶的傳動比為4，所以電動機的角速度w=3r/s。如圖10：圖10 粉盒 粉盒是用來承裝粉絲，并通過螺栓固定在齒形皮帶上從而達(dá)到傳送粉絲的目的。 考慮到工廠生產(chǎn)車間占地面積，設(shè)計烘干機生產(chǎn)線總長約34m，其中進(jìn)料段長約3m；共有8臺熱風(fēng)機，間距3～4m；另有3臺排濕風(fēng)機，分布在第一臺與第二臺熱風(fēng)機之間、第四臺與第五臺熱風(fēng)機之間、第六臺與第七臺熱風(fēng)機之間，第一臺排濕風(fēng)機離進(jìn)料段約3m，第二臺與第一臺排濕風(fēng)機間距為11m，第三臺與第二臺間距約為7m。（2）干燥溫度為40℃時所得粉絲顏色較亮、較白，通透性好，氣泡較多，局部發(fā)白；干燥溫度為50℃時所得粉絲顏色較暗，通透性一般，氣泡較少；干燥溫度為60℃時所得粉絲大部分發(fā)白，有大量氣泡。《Pro/E中文野火版教程》 清華大學(xué)出版社。 8 楊丹彤。Abstract:In industrial and agricultural production, the drying technology has been widely used, but the research progress of this guide is very slow. The traditional air drying method has no longer applies modern production, and to guarantee the quality of dry, dry technology research in the food processing industry has involves various products, the main methods are: mechanical dry, physical chemistry dry, hot air drying, vacuum drying, freeze drying, medium contact drying, radiation dry, etc.The design of the dryer is six sections fan, air dryer by setting each segment of temperature and drying time, the optimal design parameters, and get the best effect. Based on the existing drying equipment, and by adjusting the steam source and fan system to control the temperature, and by adjusting the length of the belt transmission control each segment of the drying time, through the control of transmission speed to realize fans dry. Based on piecewise type fan dryer, the transmission system of dryer, drying system and testing system using proe plete equipment 3d design.Key words: segmented fans dryer, drying, driving system and drying system, detection system
