1、首先關閉進料泵和進料閥門、進洗液或進風裝置和閥門，然后按住操作面板上的“松開”按鈕，活塞桿帶動壓緊板退回，退至合適位置后，放開按住的“松開”按鈕，人工逐塊拉動濾板卸下濾餅，同時清理粘在密封面處的濾渣，防止濾渣夾在密封面上影響密封性能，產生滲漏現象。
2、板框式壓濾機是很成熟的脫水設備，在污泥脫水項目上應用很多。壓濾機將帶有濾液通路的濾板和濾框平行交替排列，每組濾板和濾框中間夾有濾布，用壓緊端把濾板和濾框壓緊，使濾板與濾板之間構成一個壓濾室。污泥從進料口流入，水通過濾板從濾液出口排出，泥餅堆積在框內濾布上，濾板和濾框松開后泥餅就很容易剝落下來，具有操作簡單，濾餅含固率高，適用性強等優點。
3、板(ban)(ban)(ban)框式(shi)壓(ya)(ya)濾機(ji)主要由固定板(ban)(ban)(ban)、濾框、濾板(ban)(ban)(ban)、壓(ya)(ya)緊板(ban)(ban)(ban)和(he)壓(ya)(ya)緊裝(zhuang)置(zhi)組成。制造(zao)板(ban)(ban)(ban)、框的(de)(de)(de)材料(liao)有(you)金屬、木(mu)材、工(gong)(gong)程塑料(liao)和(he)橡膠等并有(you)各(ge)種形式(shi)的(de)(de)(de)濾板(ban)(ban)(ban)表面槽作(zuo)(zuo)(zuo)為排液通(tong)路，濾框是中空的(de)(de)(de)。多塊濾板(ban)(ban)(ban)、濾框交(jiao)替排列，板(ban)(ban)(ban)和(he)框間(jian)夾過濾介質（如濾布），濾框和(he)濾板(ban)(ban)(ban)通(tong)過兩個(ge)支耳，架(jia)在水(shui)平的(de)(de)(de)兩個(ge)平等橫梁(liang)上(shang)，一端(duan)是固定板(ban)(ban)(ban)，另一端(duan)的(de)(de)(de)壓(ya)(ya)緊板(ban)(ban)(ban)在工(gong)(gong)作(zuo)(zuo)(zuo)時通(tong)過壓(ya)(ya)緊裝(zhuang)置(zhi)壓(ya)(ya)緊或拉開。壓(ya)(ya)濾機(ji)通(tong)過在板(ban)(ban)(ban)和(he)框角(jiao)上(shang)的(de)(de)(de)通(tong)道(dao)或板(ban)(ban)(ban)與(yu)框兩側伸出(chu)(chu)的(de)(de)(de)掛耳通(tong)道(dao)加(jia)料(liao)和(he)排出(chu)(chu)濾液。濾液的(de)(de)(de)排出(chu)(chu)方式(shi)分(fen)明流和(he)暗流兩種、在過濾過程中濾餅在框內集聚。一般板(ban)(ban)(ban)框式(shi)壓(ya)(ya)濾機(ji)的(de)(de)(de)工(gong)(gong)作(zuo)(zuo)(zuo)壓(ya)(ya)力為0.3-0.5MPa，壓(ya)(ya)濾機(ji)工(gong)(gong)作(zuo)(zuo)(zuo)壓(ya)(ya)力為1-2MPa。
