工作原理
LGCX為立式刮刀抽吸卸料自動離心機(jī)，液/固混合流體通過進(jìn)料管進(jìn)入離心機(jī)轉(zhuǎn)鼓內(nèi)(可在低速或中速進(jìn)料)，在離心力場作用下，通過濾片截留固相，濾出液相。持續(xù)進(jìn)料，直至料滿，停止進(jìn)料，如工藝需要時(shí)則對濾餅進(jìn)行洗滌、提純，同時(shí)將洗滌液濾出。進(jìn)一步脫液，直至達(dá)到分離要求。降至低速，刮刀將大部分濾餅刮下，同時(shí)氣流抽吸裝置將濾餅抽出，完成一次工作循環(huán)。刮刀動作與氣流抽吸裝置通過料位探測自動匹配聯(lián)動。
主要特點(diǎn)是無基礎(chǔ)整體安裝，可整機(jī)移動；全密閉形式；可在極低速下或中速進(jìn)料，無滴液；卸料方式為刮刀+氣流抽吸，所需的安裝空間小，上部自動卸料，易清洗。
Operating principle
LGCX automatic vertical bottom suction scraper discharge centrifuge. Mixed solid and liquid fluids enters centrifuge drum via feed pipe(at low or medium speed ).
acting on the centrifugal position. Liquid-solid mixed fluid intercept the solid phase through the filter to filter out the liquid phase.
Centrifuge continues to feed until full. Then stop. Solid cake is rinsed and purified when the process requires. And the rinsing liquid is filtered out meanwhile. Centrifuge further filter until the separation requirements are met.
At low speed. the scraper scrape off most of the solid cake. At the same time the air suction device pulls out the filter cakes to complete a working cycle. Automatic matching of scraper action&airflow suction device through material level detection.
The main feature is no foundation integrated installation. the whole machine can be moved. Fully closed form. Can be fed at very low speed or at medium speed without dripping. Discharge mode is air suction with scraper. Small installation space required. Top automatic discharge. Easy to clean.
