Reception of Material from Trucks
Saxlund have essentially three types of Reception Systems which can be supplied as units or as part of an integrated plant by Saxlund.
A hydraulically actuated lid opens to allow trucks to tip material into the reception silo / bunker. A Sliding Frame or Push Floor positioned on the baseplate in the flat bottomed silo reciprocates across the floor promoting mass flow and discharging directly into –
- For Sludge Cake – silo bottom pump(s)
- For any material – Discharge Screw(s)
The truck approaches the screw bunker via a short section of ramp inclined at 3°. As the truck reverses up against two wheel stops a magic eye causes a roller shutter door to open. In the bottom of a wedge shaped reception bunker there are six inclined shaftless screw conveyors supported in stainless steel troughs. The screws provide an ‘active bottom’ to the bunker. The bunker structure has extended high side plates and a horizontal and curved roller shutter door to close and seal above the bunker/screws after a lorry has tipped its load.
Once tipped the cake material is pulled towards the discharge head (top) of the bunker by the shaftless screws and discharges directly into a transfer shaftless screw conveyor. This inclined conveyor transfer the cake away from the bunker screw a progressive cavity blending pumps (by others) sitting on ground level.
The SAX-TDS is designed to allow Moving Floor trailers to reverse, dock into the system and discharge materials without spillage into a conveying system. The SAX-TDS utilises screw conveyors to meter the material as it is removed from the trailer and discharge into a chain or belt conveyor for transportation onto the next process.
