螺(luo)旋輸送(song)(song)(song)(song)機代(dai)替了傳統的膠帶(dai)式(shi)輸送(song)(song)(song)(song)機，它具備了：維修(xiu)簡(jian)單、污染少(shao)、噪音小、工作效(xiao)率高等優點(dian)。迅速(su)被人們重視。不但能運送(song)(song)(song)(song)老式(shi)設備無法(fa)運送(song)(song)(song)(song)的輕(qing)軟、細小、帶(dai)狀漂浮(fu)物(wu)質，而(er)且還(huan)能將砂水分離(li)，污物(wu)壓榨。外形美觀、結構(gou)合(he)理。
機(ji)械格柵廠家 主要由機(ji)架、驅動(dong)裝置、齒(chi)(chi)(chi)耙(pa)(pa)及傳動(dong)鏈條組成(cheng)(cheng)。由ABS工程塑(su)料、尼(ni)(ni)龍(long)6、尼(ni)(ni)龍(long)1010或(huo)不銹鋼(gang)制成(cheng)(cheng)特(te)殊形(xing)狀的耙(pa)(pa)齒(chi)(chi)(chi)按一定次(ci)序裝配在齒(chi)(chi)(chi)耙(pa)(pa)軸上，形(xing)成(cheng)(cheng)一條封閉的耙(pa)(pa)齒(chi)(chi)(chi)鏈。水下柵片（耙(pa)(pa)齒(chi)(chi)(chi)）截留污物沿軌上行，當達到項部(bu)時，因彎軌和齒(chi)(chi)(chi)輪的導向(xiang)作用(yong)，使(shi)相(xiang)鄰耙(pa)(pa)齒(chi)(chi)(chi)間產(chan)生相(xiang)對推移運動(dong)，將污物外推，依自重(zhong)卸入污物盛器內。同時特(te)制轉(zhuan)刷將耙(pa)(pa)齒(chi)(chi)(chi)上微(wei)量殘留污物剔除(chu)干凈。
