工作原理
LGCX为立式刮刀抽吸卸料自动离心机，液/固混合流体通过进料管进入离心机转鼓内(可在低速或中速进料)，在离心力场作用下，通过滤片截留固相，滤出液相。持续进料，直至料满，停止进料，如工艺需要时则对滤饼进行洗涤、提纯，同时将洗涤液滤出。进一步脱液，直至达到分离要求。降至低速，刮刀将大部分滤饼刮下，同时气流抽吸装置将滤饼抽出，完成一次工作循环。刮刀动作与气流抽吸装置通过料位探测自动匹配联动。
主要特点是无基础整体安装，可整机移动；全密闭形式；可在极低速下或中速进料，无滴液；卸料方式为刮刀+气流抽吸，所需的安装空间小，上部自动卸料，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.
