Slurry pan for collecting e.g. solid excrement, of pig, has Archimedes screws placed in top part and bottom of gutter to transport solid and liquid excrements collected in pan's lower part and gutter's bottom, respectively, outside of pan

摘要

The pan (100) has a transport device formed by an Archimedes screw (106) or swirl plate, comprising a wall (114) in continuous with slope walls (104), where the wall has U shaped gutter. An Archimedes screw (108) placed at a top part of the gutter transports solid excrements collected in a lower part of the pan, outside of the pan. A filtering wall (116) extends under the device, and passes liquid excrements. The screw (106) is placed in the bottom of the gutter under the wall (116) for transporting the liquid excrements collected in the bottom of the gutter outside of the pan.
