1、本科畢業(yè)論文(設(shè)計)選煤廠周邊傳動濃縮機的設(shè)計選煤廠φ30米膠輪式周邊傳動濃縮機的設(shè)計摘要近年來隨著生活水平的提高,城市生活污水和工業(yè)廢水的排放量也逐年遞增。解決城市水污染的根本出路在于建設(shè)城市污水處理廠。我國在城市污水處理廠建設(shè)方面成績卓越。沉淀池作為污水處理廠的常規(guī)水處理構(gòu)筑物,在水處理廠中發(fā)揮重要的作用。而作為水處理中最基本方法的沉淀法,在水處理的不同階段都發(fā)揮著重要的作用。濃縮設(shè)備在選礦廠一般用于過濾之前的精礦濃縮或尾礦脫水,還可廣泛用于煤炭、化工、建材以及水源和污水處理等工業(yè)中含固料漿液的濃縮和凈化。濃縮機主要由圓形濃縮池和
2、耙式刮泥機兩大部分組成,濃縮池里懸浮于礦漿中的固體顆粒在重力作用下沉降,上部則成為澄清水,使固液得以分離,沉積于濃縮池底部的礦泥由耙式刮泥機連續(xù)地刮集到池底中心排礦口排出,而澄清水則由濃縮池上沿溢出。耙式濃縮機通??煞譃橹行膫鲃邮胶椭苓厒鲃邮絻纱箢?,構(gòu)造大致相同,都是由池體、耙架、傳動裝置、給料裝置、排料裝置、安全信號和耙架提升裝置組成。濃縮機機主要有周邊傳動式、中心傳動式、矩形平流池桁車式、鏈傳動式等。它是排泥機械中的一種常見設(shè)備,它是沉淀池不可缺少的設(shè)備。本設(shè)計研究的刮泥機為周邊傳動式。關(guān)鍵詞:濃縮機;周邊傳動;功率計算;整體設(shè)計
