  • Patent number: 10604705
    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.

  • Publication number: 20190093949
    Abstract: A rotating seal mechanism, provided between a fixed body and a rotating body, and comprising: a sealing assembly rotatably connected to the rotating body and disposed on a circumference of the rotating body; a flexible connecting body connecting the sealing component and the fixed body; and a circumferential limiting component disposed on the sealing assembly. The rotating seal mechanism compensates for bouncing movement between and sealingly joins the fixed body and the rotating body.
