6 FLOTTWEG DECANTER <strong>CENTRIFUGE</strong>S Feed The slurry is fed through a stationary pipe into the feed zone located in the center of the scroll. The product is then accelerated circumferentially and delivered through distribution ports into the bowl. Bowl The bowl has a cylindrical/ conical shape and rotates at a pre-set speed optimal for the application. The slurry rotates solids discharge FLOTTWEG DECANTER for the liquid-solid separation with gravity overflow of the liquid phase (centrate) with a different scroll design or by modifying an existing scroll. Scroll pitch and single or multiple flight configurations are important design variables. with the bowl at the operating speed and forms a concentric layer at the bowl wall. The solids contained in the slurry are deposited against the bowl wall by centrifugal force. The length of the cylindrical bowl section and the cone angle are selected to meet the specific requirements of an application. Scroll The scroll rotates at a slightly different speed than the bowl Eccentric – adjustable weir plates (patented) and conveys the deposited solids toward the conical end of the bowl. This differential speed determines the residence time of the solids in the bowl. Residence time is an important variable for the dry solids content. It can be adjusted by changing the differential speed of the scroll thus providing optimal separation. If the physical properties of the slurry change, FLOTTWEG DECANTERS can be supplied liquid discharge by gravity feed inlet
Solids discharge Settled solids are ejected through ports at the conical end of the bowl into the solids housing and fall through to the discharge chute. Materials of construction FLOTTWEG uses high-quality stainless steel for all wetted areas. Bowl and scroll castings are made from centrifugal cast high strength and corrosion resistant stainless steel. solids discharge Rotor bearing A special selection and arrangement of bearings provides long life and exceptional reliability. A central lubrication system supplies either grease or oil to bearings. Overflow weirs The clarified liquids flow to the cylindrical end of the bowl where they exit over weir plates. Easily adjustable precision weir plates allow for the FLOTTWEG DECANTER with pressurized centrate discharge precise adjustment of the pond depth in the bowl. Overflow is then collected in a centrate chamber and discharged by gravity. Impeller (skimmer) The clarified liquid can also be decanted with an impeller and discharged from the bowl under pressure. This eliminates the need for a separate centrate pump. The FLOTTWEG adjustable impeller is an engi- Adjustable impeller neering refinement that permits quick and precise adjustment of the pond depth during operation to accommodate changing conditions. liquid discharge under pressure feed inlet
