Definitions

  • the temperature of the pellets For storage, the temperature of the pellets must be lowered so that the risk of self-ignition due to the thermal energy carried in the pellets is avoided.
  • the cooling device is arranged below the press. This enables an extremely compact design. Since there is enough space under the press for the cooling device, this space can be used sensibly.
  • the cooling device has a screw conveyor.
  • the pellets are evenly cooled down as they are transported through the screw conveyor. This means, for example, that there are no hot spots.
  • the cooling device has a control device which is designed to control the drive device and / or the fluid cooling on the basis of temperature data determined by the temperature sensor.
  • the temperature sensor is provided in an exit area of the screw conveyor.
  • the temperature sensor is arranged inside the screw conveyor.
  • the temperature sensor is preferably designed to determine the temperature of the pellets leaving the screw conveyor. The temperature determined corresponds in particular to the storage temperature at which the pellets are stored.
  • control device is designed to control the drive device and / or the fluid cooling on the basis of fill level data determined by the fill level sensor.
  • the control device can in particular be connected to the fill level sensor wirelessly or by cable.
  • the conveying speed of the screw conveyor in particular can be increased.
  • the endless conveyor is preferably arranged in a chamber, in particular an endless conveyor housing.
  • the chamber is preferably closed except for openings in the cover and an outlet, e.g. a fluid discharge or suction point.
  • the endless conveyor can have a separate drive, in particular a motor.
  • the container can be a mobile box, which can be transported with a truck, for example.
  • a conventional ISO container i.e. a standardized sea freight container
  • a swap body can be used as the housing.
  • a swap body is also called a swap body and is suitable for transport on a truck.
  • a fill level sensor 24 is also provided in the screw conveyor 10.
  • a cover 28 and the underside 30 of the screw trough 16 have several openings 32.
  • the cover 28 and / or the underside 30 of the screw trough 16 can be designed as a perforated plate or sieve surface.
  • the pellets for example pellets
  • the cooling device As with the solid arrows in Fig. 1 shown, the pellets, for example pellets, are filled into the cooling device at an entry area of the screw conveyor 10.
  • the pellets are continuously conveyed from the entrance area to an exit area. In this way, in particular, uniform cooling of the pellets is guaranteed.
  • the cooling air can preferably be monitored between the cooling device and the cyclone. If necessary, water is dosed with a spray mist.
  • the conveying speed of the screw conveyor 10 can be reduced, for example. This can take place in that the control device 26 forwards corresponding control signals to the drive device 18.
  • control device 26 can also control the fluid cooling 20, in particular the fan 22, and, for example, increase the fluid throughput.
  • the temperature at which the pellets leave the cooling device can thereby be lowered.
