1、蘭州工業(yè)學(xué)院畢業(yè)設(shè)計(jì)(論文)題目錘片式秸稈粉碎機(jī)設(shè)計(jì)系別機(jī)電工程學(xué)院專業(yè)機(jī)械設(shè)計(jì)與制造班級機(jī)設(shè)11-1班姓名學(xué)號指導(dǎo)教師(職稱)日期2014.03.10II摘要隨著經(jīng)濟(jì)和社會的發(fā)展,生物質(zhì)秸稈資源大量過剩,作為燃料直接燃燒,熱效率低;就地焚燒,又造成嚴(yán)重的環(huán)境污染和資源浪費(fèi)。因此,研究生物質(zhì)能轉(zhuǎn)換技術(shù),將豐富的農(nóng)林廢棄物資源轉(zhuǎn)換為優(yōu)質(zhì)燃料,變廢為寶,是保護(hù)生態(tài)環(huán)境,促進(jìn)農(nóng)業(yè)可持續(xù)發(fā)展的重要課題。由于大部分生物質(zhì)原料在開發(fā)利用前期都需要進(jìn)行粉碎加工處理,以便進(jìn)一步加工利用。因此,粉碎加工技術(shù)已越來越受到人們的重視。目前多種
2、錘片式和盤片式粉碎機(jī)在農(nóng)業(yè)生產(chǎn)中,已經(jīng)得到廣泛的應(yīng)用,而且應(yīng)用操作簡單方便,但是這兩種機(jī)型在性能上各有不同。為此,本設(shè)計(jì)將錘片式和盤片式優(yōu)點(diǎn)性能結(jié)合,設(shè)計(jì)出了性能優(yōu)良的的粉碎機(jī)。本次畢業(yè)設(shè)計(jì)所做主要工作如下:1、了解了與粉碎機(jī)相關(guān)的知識;熟悉粉碎機(jī)粉碎原理,調(diào)查了國內(nèi)外應(yīng)用性能現(xiàn)狀與市場前景。2、通過查閱資料、市場調(diào)研確定了多功能粉碎機(jī)相關(guān)的總體方案。3、完成了詳細(xì)的設(shè)計(jì)說明書及答辯材料。關(guān)鍵詞:粉碎機(jī);錘片式;設(shè)計(jì)IIIABSTRACTAlongwiththedevelopmentofeconomyandsociety
