BÖRGER BIOSELECT Screwpress Separator
The media to be separated find their way through the inlet opening into the vessel-like Bioselect. The outer cylinder is separated from the auger by a roundly sealed wire-wound screen pipe. The auger has a frictional connection to the drive. The imported liquid flows into the screen area next to the drive. The liquid flows through the wedge wire screen into the outer vessel area. The liquid drains through the liquid outlet .
The solid contents remain on the screen surface. They are conveyed into the press channel by the rotating auger. Powerful subsequent dewatering takes place in the press channel . The rotating auger has a Multi Disc (sealing disk), which can be shifted in axial direction, at the non-drive end. The adjusting unit presses the Multi Disc against the auger and the compressed thick matter plug. When the thrust force of the plug is greater than the spring force of the Easy Shift unit , a slot for discharging is created by axial movement. A scraper edge is used to loosen and expel the solids.
AUGER WITH PROFILE GROOVE
Fibers are caught in the profile groove of the auger . The fibers function as a sealing brush. Metallic rubbing between the auger and the wedge wire screen (2) is avoided by the brush. This unique technology increases the service life of the wedge wire screen and auger many times over. In addition, the brushing surface cleans the wedge wire screen very thoroughly. Additional cleaning by the operator is not necessary.
The installation options of the Bioselect are as versatile as their requirements. Whether attached to a simple wall bracket, installed on a movable frame with an upstream macerator or as a mobile version with a conveyor belt – the application options of the Bioselect are unique. Several separators can be installed next to each other – also as mobile versions – for very high separation quantities.
