Abstract
A rotary cooler is provided, consisting of a plurality of transport tubes for transporting material to be cooled, wherein the plurality of transport tubes are arranged about an axis of rotation and are adapted to be filled jointly via a filling region with material to be cooled, characterized in that each transport tube is arranged substantially concentrically in a cooling tube in which a cooling medium flows and cools the material to be cooled via the wall of the transport tube. Furthermore, a method for operating said rotary cooler is provided.
Claims16
A rotary cooler comprising:
- a plurality of open transport tubes having a circular cross-section for transporting material to be cooled indirectly,
- wherein the plurality of transport tubes are arranged about an axis of rotation and are each adapted to be filled jointly via a filling region with material to be cooled,
- wherein each transport tube arranged concentrically within a respective cooling tube of a plurality of cooling tubes, and the indirect cooling of the material to be cooled takes place via the plurality of transport tubes which are flown around by a cooling medium within the plurality of cooling tubes and cools the material to be cooled via a wall of the transport tube, and
- wherein the plurality of cooling tubes are connected to a single tube via supply tubes which are arranged in a spoke-like manner, wherein the cooling medium is fed into the single tube and flows via the supply tubes into the cooling tubes.
A method for cooling bulk material using a rotary cooler comprising a plurality of transport tubes for transporting material to be cooled indirectly, wherein the plurality of transport tubes are arranged about an axis of rotation and are adapted to each be filled jointly via a filling region with material to be cooled, wherein each transport tube is arranged concentrically within a respective cooling tube of a plurality of cooling tubes and the indirect cooling of the material to be cooled takes place via the plurality of transport tubes which are flown around by cooling medium and cools the material to be cooled via a wall of the transport tube, wherein the plurality of cooling tubes are connected to a single tube via supply tubes which are arranged in a spoke-like manner, wherein the cooling medium is fed into the single tube and flows via the supply tubes into the cooling tubes, the method comprising the steps of:
- introducing material to be cooled in an open transport tube having a circular cross-section which is enclosed by a cooling tube in which a cooling medium flows, wherein the cooling medium is water;
- transporting the material to be cooled from one end of the transport tube to the other end thereof, wherein the material to be cooled is cooled by the cooling medium;
- rotating the transport tubes about an axis;
- and
- outputting the cooled transport material.
