Abstract:
A material heating device comprises a rotary kiln, a plurality of heat exchange tubes, a hot air hood, a high-temperature gas input mechanism, an exhaust-gas collecting chamber, and an exhaust-gas output pipeline. The rotary kiln is provided with a material feed end and a material discharge end. The heat exchange tubes are in the rotary kiln. The hot air hood is outside the rotary kiln. The air inlet ends of the heat exchange tubes communicate with the hot air hood, and the air outlet ends of the heat exchange tubes communicate with the exhaust-gas collecting chamber. The exhaust-gas collecting chamber communicates with the exhaust-gas output pipeline. The hot air hood communicates with the high-temperature gas input mechanism, and the cavity between the heat exchange tubes and the heat insulation layer of the rotary kiln is a material channel. The heat exchange tubes are directly in contact with the material.

Claim (Index 1):
A material heating device, comprising a rotary kiln, a plurality of heat exchange tubes, a hot air hood, a high-temperature gas input mechanism, an exhaust gas collecting chamber and an exhaust gas output pipeline, the rotary kiln being provided with a material feed end and a material discharge end,\n wherein the plurality of heat exchange tubes are provided in the rotary kiln, uniformly distributed in a circumferential direction, parallel to an axis of the rotary kiln and adjacent to an inner wall of the rotary kiln, heat exchange tube brackets configured for supporting the plurality of heat exchange tubes are provided on the inner wall of the rotary kiln, a heat insulation layer is provided on the inner wall of the rotary kiln, a space between the plurality of heat exchange tubes and the rotary kiln is used as a material channel, the hot air hood is provided at a periphery of a rotary kiln housing, an air inlet end of each heat exchange tube is in communication with the hot air hood, each heat exchange tube is connected with the hot air hood through an elbow, with the elbow being a part of the each heat exchange tube, an air inlet elbow end of each heat exchange tube is connected with the rotary kiln housing, the hot air hood and the rotary kiln housing form, in combination, a hot air distribution chamber, an air outlet end of each heat exchange tube is in communication with the exhaust gas collecting chamber that is in communication with the exhaust gas output pipeline, the exhaust gas collecting chamber is provided at the material feed end of the rotary kiln, the hot air hood is in communication with the high-temperature gas input mechanism, a sealing mechanism is provided at an outer side of a portion of the hot air hood where the hot air hood is connected with the rotary kiln housing, the hot air hood is located in a middle of the rotary kiln and is close to the material discharge end, some of the plurality of heat exchange tubes are arranged in a path directly from the hot air hood to the material feed end of the rotary kiln, and the rest of the plurality of heat exchange tubes are arranged in a path which goes firstly towards the material discharge end and then turns 180 degrees to go towards the material feed end.
