Removal system DRS

In many applications, heavy material is separated from liquid media in order to avoid damage and blockages to downstream system components such as pumps and valves, for example from stones or metal parts. The heavy material settles as usual in the calming zone. The piston of the DRS then push it towards the removal aperture while at the same time the passage to the RotaCut RCX / DebrisCatcher is closed. The medium included with the heavy material returns to the machine's working area via a bypass. In the next step, the heavy material is discharged by the piston with only about 15 l of medium. Everything takes place during operation, without the DebrisCatcher or RotaCut RCX having to be switched off or opened - as is usually the case. Compared to previous solutions, the work is completed in a fifth of the time. When combined with a control, this process can be performed automatically. In biogas plants in particular, large amounts of heavy material usually accumulate. Stones, metal parts, porcelain, stoneware etc. get into the process via liquid manure as well as dung, organic waste etc. Separated by a heavy material separator, the final removal has so far involved a great deal of manual effort. In addition to the actual heavy material, large quantities of manure or suspension also escape, which then have to be fed back into the process. The Debris Removal System (DRS) discharges the separated heavy material during ongoing operation with no need to switch off or open the solid matter feeder or the RotaCut / foreign matter separator.
