Patent ID: 7201573

Claim:
A device for emptying hot particle material from a chamber into a transport container, comprising a first pipe that can be inserted into the particle material in the chamber and communicates into the container; and a second pipe that is connected from the container to a vacuum source via a powder separator, wherein the first and second pipes communicate with an upper part of the container and the pipes are spaced from each other to permit separation of particle material in the container, the container has a lower, downwardly narrowing part with an outlet therein, the outlet has a valve, a vertical chute surrounds the outlet and extends downwardly from the outlet, the chute has an evacuation pipe for withdrawal of a mixture of air and powder that is generated inside the chute while the particle material is being emptied through the outlet and the outlet valve, the container includes a heat-exchanger to cool the particle material deposited in the container, at least one compressed air tube extends into the interior of the container and the tube has a plurality of openings from which air flows, openings are open to the powder material therein, the compressed air tube has an inlet end that is supplied from a compressed air source and has a cut-off valve controlled by software for time-controlled forcing of compressed air into the powder material through the openings.
