一、常見重點(diǎn)問題答疑I.AnswerstoFrequentlyAskedKeyQuestions1.在啟動壓濾機(jī)前，需要檢查哪些關(guān)鍵部件？請列舉3項(xiàng)并說明檢查目的。1.Whatkeycomponentsneedtobecheckedbeforestartingthefilterpress?Pleaselist3itemsandexplainthepurposeoftheinspection.解答：Answer:（1）濾板：檢查是否有破損、排列是否整齊，目的是防止過濾時(shí)礦漿泄漏。(1)Filterplate:Checkwhetheritisdamagedandneatlyarranged,inordertopreventslurryleakageduringfiltration.（2）濾布：檢查是否有破洞、折疊，目的是保證濾液澄清，避免“跑渾”。(2)Filtercloth:Checkwhetherthereareholesorfolds,inordertoensurethatthefiltrateisclearandavoid"turbidleakage".（3）油壓系統(tǒng)：檢查油位、油質(zhì)和壓力是否正常，目的是確保濾板能壓緊，不漏液。(3)Hydraulicsystem:Checkwhethertheoillevel,oilqualityandpressurearenormal,inordertoensurethatthefilterplatecanbepressedtightlywithoutleakage.2.操作壓濾機(jī)時(shí)，有哪些絕對不能做的事？請舉2個(gè)例子并說明原因。2.Whatarethethingsyoumustnotdowhenoperatingafilterpress?Pleasegive2examplesandexplainthereason.解答：Answer:（1）嚴(yán)禁在濾板壓緊時(shí)伸手到濾板之間：濾板壓力大（可達(dá)1.0MPa），容易夾傷手。(1)Itisstrictlyforbiddentoreachoutbetweenthefilterplateswhenthefilterplatesarepressed:Thehighpressureoffilterplates(upto1.0MPa)caneasilypinchyourhands.（2）開壓或卸壓時(shí)不能站在設(shè)備兩側(cè)：壓力變化可能導(dǎo)致礦漿飛濺，容易傷人。(2)Donotstandonbothsidesoftheequipmentwhenopeningorreleasingpressure:Pressurechangesmaycauseslurrytosplashandeasilyhurtpeople.3.卸完濾餅后，為什么必須清洗濾板和濾布？日常檢查濾布時(shí)要注意什么？3.Whydoyouhavetocleanthefilterplateandfilterclothafterunloadingthefiltercake?Whatshouldyoupayattentiontowhencheckingfilterclothdaily?解答：Answer:（1）清洗原因：防止殘留的濾渣堵塞濾布或進(jìn)料孔，影響下次過濾效果（比如濾液變渾、進(jìn)料不暢）。(1)Reasonforcleaning:Preventtheresidualfilterresiduefromblockingthefilterclothorfeedholesandaffectingthenextfiltrationeffect(suchasturbidfiltrateandunsmoothfeeding).（2）濾布檢查要點(diǎn)：看是否有破洞、邊緣是否脫開，發(fā)現(xiàn)破損要及時(shí)更換，避免過濾失效。(2)Keypointsforinspectionoffiltercloth:Checkifthereareholesandwhethertheedgesaredetached.Ifanydamageisfound,itshallbereplacedintimetoavoidfiltrationfailure.二、常見難點(diǎn)問題答疑II.AnswerstoFrequentlyAskedDifficultQuestions1.壓濾機(jī)的過濾壓力和壓榨壓力一般控制在什么范圍？為什么不能超過這個(gè)范圍？1.Whatrangearethefiltrationpressureandsqueezingpressureofthefilterpressgenerallycontrolled?Whycan'titgobeyondthatrange?解答：過濾壓力：0.8-1.0MPa；壓榨壓力：1.2-1.5MPa。Answer:Filtrationpressure:0.8-1.0MPa;pressingpressure:1.2-1.5MPa.原因：壓力太低，濾餅水分高、濾液可能渾；壓力太高，會損壞濾板、濾布或油壓系統(tǒng)，增加設(shè)備故障風(fēng)險(xiǎn)。Reason:Ifthepressureistoolow,themoisturecontentofthefiltercakeishigh,andthefiltratemaybeturbid;ifthepressureistoohigh,thefilterplate,filterclothoroilpressuresystemwillbedamaged,increasingtheriskofequipmentfailure.2.過濾時(shí)發(fā)現(xiàn)濾液“跑渾”（渾濁），可能是什么原因？該怎么處理？2.Whatmaybethereasonifthe"turbidleakage"(turbidity)offiltrateisfoundduringfiltration?Howtodealwithit?解答：Answer:（1）可能原因：濾布破損、濾板錯位（沒對齊）、濾布上粘了太多渣。(1)Possiblereasons:Damagedfiltercloth,misalignedfilterplate,andtoomuchslagstuckonthefiltercloth.（2）處理步驟：立即停機(jī)→檢查濾布是否有破洞（有則更換）→調(diào)整濾板位置（對齊）→清理濾布上的渣→重新開機(jī)過濾。(2)Processingsteps:Shutdownimmediately→Checkwhetherthereareholesinthefiltercloth(replacethemifthereare)→Adjustthepositionofthefilterplate(alignment)→Cleantheslagonthefiltercloth→Restartthemachineforfiltration.3.什么時(shí)候需要對濾餅進(jìn)行洗滌和壓榨？這兩個(gè)操作的目的是什么？3.Whendoesthefiltercakeneedtobewashedandpressed?Whatisthepurposeofthesetwooperations?解答：Answer:（1）時(shí)機(jī)：當(dāng)濾餅形成（進(jìn)料一段時(shí)間，濾液流量變小時(shí)），先洗滌再壓榨。(1)Timing:Whenthefiltercakeisformed(thefiltrateflowratebecomessmallerafterfeedingforaperiodoftime),washingisfollowedbypressing.（2）目的：(2)Purpose:①洗滌：沖掉濾餅表面殘留的雜質(zhì)，提高濾液純度；①Washing:Washawaytheimpuritiesremainingonthesurfaceofthefiltercaketoimprovethepurityofthefiltrate;②壓榨：用高壓水或空氣擠出濾餅中的水分，降低濾餅含水率，方便后續(xù)處理（如運(yùn)輸、回收）。②Pressing:Use
