Abstract
A rotary tube kiln, with a rotatably mounted rotary tube, which has a motorized drive, a mounting, a material inlet and a material outlet, wherein the interior space of the rotary tube has a process space, the inside atmosphere of which is separate from the outside atmosphere. The process space is sealed off from a pressure space by means of a first seal and the pressure space is sealed off from the outside atmosphere by means of a second seal and, by means of a pressing device, a first pressing force can be applied to the first seal and a second pressing force can be applied to the second seal, the first pressing force can be set independently of the second pressing force and, during operation, the internal pressure of the pressure space is higher than the internal pressure of the process space.
Claims13
A rotary kiln comprising:
- a rotatably mounted kiln tube, which has a motor drive, a bearing, a material inlet and a material outlet, wherein a rotary kiln interior has a process chamber, an inner atmosphere of which is separated from an outer atmosphere;
- a first seal which seals the process chamber and inner atmosphere from a pressure chamber, and a second seal which seals the pressure chamber from the outer atmosphere, so that the first seal seals the inner atmosphere, the pressure chamber is sealed between the first seal and the second seal, and the second seal seals the pressure chamber from the outer atmosphere
- a pressing device which loads the first seal with a first pressing force, and the second seal with a second pressing force, such that the first pressing force is adjustable independently of the second pressing force, and
- a gas connection for generating an internal pressure in the pressure chamber, the internal pressure of the pressure chamber being higher than an internal pressure of the process chamber during operation.
