刮刀(dao)清洗過濾(lv)器(qi)是一種利用濾網直接攔截水中的雜質，去除水體懸浮物、顆粒物，降低濁度，凈化水質，減少系統污垢、菌藻、銹蝕等產生,以凈化水質及保護系統其他設備正常工作的精密設備，水由進水口進入自清洗過濾器機體，由于智能化（PLC、PAC）設計，系統可自動識別雜質沉積程度，給排污閥信號自動排污。
刮刀清洗過濾器與反沖(chong)型自清洗(xi)水(shui)過(guo)濾(lv)(lv)(lv)(lv)(lv)器(qi)(qi)(qi)(qi)不同，刮(gua)刀過(guo)濾(lv)(lv)(lv)(lv)(lv)器(qi)(qi)(qi)(qi)不但用(yong)于水(shui)過(guo)濾(lv)(lv)(lv)(lv)(lv)，更廣泛適用(yong)于溶劑、酸堿液(ye)、聚合物、涂料(liao)等(deng)黏(nian)性物料(liao)的(de)自清洗(xi)過(guo)濾(lv)(lv)(lv)(lv)(lv)，效率更高(gao)，精度(du)范(fan)圍(wei)30-3000微米，可以(yi)處理(li)黏(nian)度(du)高(gao)達800,000厘泊的(de)液(ye)體，應(ying)用(yong)于水(shui)處理(li)、石(shi)化、冶金(jin)、電力、精細化工、涂料(liao)、油墨(mo)、造紙、食品(pin)飲料(liao)、制(zhi)藥、金(jin)屬(shu)加工等(deng)行業。環刮(gua)式過(guo)濾(lv)(lv)(lv)(lv)(lv)器(qi)(qi)(qi)(qi)，全自動(dong)(dong)運(yun)轉，過(guo)濾(lv)(lv)(lv)(lv)(lv)精度(du)高(gao)，性能穩定可靠(kao)，是(shi)取代傳(chuan)統手動(dong)(dong)過(guo)濾(lv)(lv)(lv)(lv)(lv)器(qi)(qi)(qi)(qi)或使用(yong)拋棄式濾(lv)(lv)(lv)(lv)(lv)材(cai)過(guo)濾(lv)(lv)(lv)(lv)(lv)器(qi)(qi)(qi)(qi)的(de)效益之選，在許多領域(yu)可以(yi)替代傳(chuan)統的(de)濾(lv)(lv)(lv)(lv)(lv)心(xin)式過(guo)濾(lv)(lv)(lv)(lv)(lv)器(qi)(qi)(qi)(qi)、袋式過(guo)濾(lv)(lv)(lv)(lv)(lv)器(qi)(qi)(qi)(qi)、籃式過(guo)濾(lv)(lv)(lv)(lv)(lv)器(qi)(qi)(qi)(qi)、振動(dong)(dong)篩過(guo)濾(lv)(lv)(lv)(lv)(lv)器(qi)(qi)(qi)(qi)等(deng)。
水(shui)由(you)入口進入，首先經過(guo)粗(cu)濾(lv)(lv)(lv)網(wang)(wang)濾(lv)(lv)(lv)掉較大顆粒(li)的雜質，然后到達細濾(lv)(lv)(lv)網(wang)(wang)。在(zai)過(guo)濾(lv)(lv)(lv)過(guo)程中(zhong)，細濾(lv)(lv)(lv)網(wang)(wang)逐漸累(lei)積水(shui)中(zhong)的臟(zang)物(wu)、雜質，形成過(guo)濾(lv)(lv)(lv)雜質層(ceng)，由(you)于(yu)雜質層(ceng)堆積在(zai)細濾(lv)(lv)(lv)網(wang)(wang)的內側，因此在(zai)細濾(lv)(lv)(lv)網(wang)(wang)的內、外(wai)兩側就形成了一個(ge)壓差。當過(guo)濾(lv)(lv)(lv)器(qi)的壓差達到預設值時(shi)，將開(kai)始自動(dong)清(qing)洗(xi)(xi)過(guo)程，此間凈水(shui)供(gong)應不斷流，清(qing)洗(xi)(xi)閥打開(kai)，清(qing)洗(xi)(xi)室及(ji)吸(xi)(xi)污(wu)(wu)(wu)器(qi)內水(shui)壓大幅度下降，通(tong)過(guo)濾(lv)(lv)(lv)筒(tong)與(yu)吸(xi)(xi)污(wu)(wu)(wu)管(guan)的壓力差，吸(xi)(xi)污(wu)(wu)(wu)管(guan)與(yu)清(qing)洗(xi)(xi)室之間通(tong)過(guo)吸(xi)(xi)嘴產生一個(ge)吸(xi)(xi)力，形成一個(ge)吸(xi)(xi)污(wu)(wu)(wu)過(guo)程。同時(shi)，電力馬達帶動(dong)吸(xi)(xi)污(wu)(wu)(wu)管(guan)沿軸向(xiang)做螺旋(xuan)運(yun)動(dong)。吸(xi)(xi)污(wu)(wu)(wu)器(qi)軸向(xiang)運(yun)動(dong)與(yu)旋(xuan)轉(zhuan)運(yun)動(dong)的結合將整個(ge)濾(lv)(lv)(lv)網(wang)(wang)內表面*清(qing)洗(xi)(xi)干凈。整個(ge)沖(chong)洗(xi)(xi)過(guo)程只需(xu)數十秒(miao)鐘(zhong)。排污(wu)(wu)(wu)閥在(zai)清(qing)洗(xi)(xi)結束(shu)時(shi)關閉。過(guo)濾(lv)(lv)(lv)器(qi)開(kai)始準備下一個(ge)沖(chong)洗(xi)(xi)周期。
