賀德克過濾器分類：過濾器(qi)按獲得過濾推動力的方法不同，分為重(zhong)力過濾器(qi)、真空過濾器(qi)和(he)加壓(ya)過濾器(qi)三類。 重力(li) 借助懸浮液的(de)重(zhong)力和位差在過(guo)濾介(jie)質上(shang)形成的(de)壓力作為過(guo)濾的(de)推動力，一般(ban)為間歇(xie)操作，如砂器。 真空(kong) 在濾液出口處形成負壓作為過濾的推動力。工業真空(kong)(kong)過濾器操作真空(kong)(kong)的jue對(dui)壓(ya)力為(2.5～8.0)×105帕。過(guo)(guo)(guo)(guo)(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)時懸(xuan)浮(fu)(fu)(fu)液(ye)(ye)的(de)(de)(de)(de)溫度應低于(yu)操(cao)作(zuo)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)下濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)液(ye)(ye)的(de)(de)(de)(de)汽化溫度。這種(zhong)過(guo)(guo)(guo)(guo)(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)器(qi)(qi)(qi)又分(fen)為間歇(xie)操(cao)作(zuo)和連(lian)續操(cao)作(zuo)兩(liang)種(zhong)。間歇(xie)操(cao)作(zuo)的(de)(de)(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)過(guo)(guo)(guo)(guo)(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)機(ji)可過(guo)(guo)(guo)(guo)(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)各種(zhong)濃(nong)度的(de)(de)(de)(de)懸(xuan)浮(fu)(fu)(fu)液(ye)(ye)。真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)過(guo)(guo)(guo)(guo)(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)器(qi)(qi)(qi)在容器(qi)(qi)(qi)外殼(ke)內(nei)充滿懸(xuan)浮(fu)(fu)(fu)液(ye)(ye)。兩(liang)側包有濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)布(bu)的(de)(de)(de)(de)濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)葉(xie)浸于(yu)懸(xuan)浮(fu)(fu)(fu)液(ye)(ye)中，濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)葉(xie)內(nei)腔與(yu)(yu)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)系統連(lian)通(tong)。濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)液(ye)(ye)吸(xi)出(chu)(chu)后(hou)由(you)導管引(yin)出(chu)(chu)，積在濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)葉(xie)表面的(de)(de)(de)(de)濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)渣在停機(ji)后(hou)清(qing)除。連(lian)續操(cao)作(zuo)的(de)(de)(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)過(guo)(guo)(guo)(guo)(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)器(qi)(qi)(qi)適于(yu)過(guo)(guo)(guo)(guo)(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)含固體(ti)顆粒較多的(de)(de)(de)(de)稠厚(hou)懸(xuan)浮(fu)(fu)(fu)液(ye)(ye)。轉鼓真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)過(guo)(guo)(guo)(guo)(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)器(qi)(qi)(qi)、內(nei)濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)面轉鼓真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)過(guo)(guo)(guo)(guo)(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)(lv)器(qi)(qi)(qi)、
