U型螺旋輸送機的機殼形(xing)狀為U型(xing)，機殼上部(bu)有U型(xing)槽蓋(gai)，故此得名。按設計形(xing)式分為：封(feng)閉式、敞開(kai)式兩種(zhong)。

U型螺旋輸送機采用DIN15261-1986工藝標(biao)(biao)準(zhun)，設(she)計(ji)制(zhi)造(zao)*符(fu)合《螺旋輸送(song)機(ji)》專業標(biao)(biao)準(zhun)。整機(ji)設(she)計(ji)構(gou)造(zao)較為簡單，由U型(xing)槽(cao)、進料口、法蘭、驅動(dong)裝(zhuang)置、襯板、上蓋等(deng)部件(jian)組成。橫截面(mian)積小(xiao)，機(ji)體(ti)的(de)密封(feng)性能好，設(she)備(bei)的(de)操(cao)作(zuo)簡單，操(cao)作(zuo)人員無安全隱患(huan)，U型(xing)輸送(song)機(ji)的(de)制(zhi)造(zao)成本較低(di)，并且該輸送(song)機(ji)的(de)能源消耗較大。

U型(xing)(xing)輸(shu)送機主要的(de)應用是運(yun)輸(shu)輸(shu)送、攪(jiao)拌混合、脫水烘干、卸料等作(zuo)業工作(zuo)。常見的(de)U型(xing)(xing)規格型(xing)(xing)號有：200，250，300，400，500，普通(tong)的(de)U型(xing)(xing)輸(shu)送機長度為：4米~50米。

U型(xing)輸(shu)(shu)送(song)(song)機(ji)(ji)(ji)有多種輸(shu)(shu)送(song)(song)方式(shi)，可(ke)(ke)以水平輸(shu)(shu)送(song)(song)、傾斜(xie)輸(shu)(shu)送(song)(song)、垂直(zhi)輸(shu)(shu)送(song)(song)等甚至可(ke)(ke)以幾種形式(shi)組合使(shi)用(yong)。該輸(shu)(shu)送(song)(song)機(ji)(ji)(ji)中間吊軸承采(cai)用(yong)滾動(dong)、滑動(dong)可(ke)(ke)互換的(de)兩種結構(gou)。該U型(xing)輸(shu)(shu)送(song)(song)機(ji)(ji)(ji)可(ke)(ke)以和其它輸(shu)(shu)送(song)(song)設備(bei)聯合工作(zuo)。并可(ke)(ke)與(yu)其他輸(shu)(shu)送(song)(song)設備(bei)或工作(zuo)裝置配合使(shi)用(yong)。螺(luo)(luo)旋(xuan)輸(shu)(shu)送(song)(song)機(ji)(ji)(ji)用(yong)途：螺(luo)(luo)旋(xuan)輸(shu)(shu)送(song)(song)機(ji)(ji)(ji)用(yong)于污(wu)水處理廠輸(shu)(shu)送(song)(song)中細格柵其柵條凈距50mm的(de)除污(wu)機(ji)(ji)(ji)柵渣和壓濾機(ji)(ji)(ji)泥餅等物(wu)料(liao)。環保(bao)性能好。采(cai)用(yong)全封閉輸(shu)(shu)送(song)(song)和易(yi)清洗的(de)螺(luo)(luo)旋(xuan)表面，可(ke)(ke)保(bao)證環境(jing)衛生和所送(song)(song)物(wu)料(liao)不受(shou)污(wu)染(ran)、不泄漏。扭距大、能耗低(di)(di)。由(you)于螺(luo)(luo)旋(xuan)無軸，物(wu)料(liao)不易(yi)堵(du)塞(sai)，排料(liao)口不堵(du)塞(sai)，因而可(ke)(ke)以較(jiao)低(di)(di)速度(du)運轉，平穩傳動(dong)，降低(di)(di)能耗。扭距可(ke)(ke)達4000N/m。輸(shu)(shu)送(song)(song)量大。
