螺帶式攪拌器的類型、尺寸及轉(zhuǎn)速,對攪拌功率在總體流動和湍流脈動之間的分配都有影響。一般說來,渦輪式攪拌器的功率分配對湍流脈動有利,而旋槳式攪拌器對總體流動有利。對于同一類型的攪拌器來說,在功率消耗相同的條件下,大直徑、低轉(zhuǎn)速的攪拌器,功率主要消耗于總體流動,有利于宏觀混合。小直徑、高轉(zhuǎn)速的攪拌器,功率主要消耗于湍流脈動,有利于微觀混合。攪拌器的放大是與工藝過程有關(guān)的復(fù)雜問題,至今只能通過逐級經(jīng)驗放大,根據(jù)取得的放大判據(jù),外推至工業(yè)規(guī)模。
螺帶式攪拌器的葉片為螺帶狀,螺帶的數(shù)量為兩到三根,被安裝在攪拌器 的螺桿上,螺帶式攪拌器的螺距決定了螺帶的外徑。螺帶式攪拌器通常是在層流狀態(tài)下操作,適用于黏度高的液體和擬塑性的流體混合。
