Problems solved by technology

[0007] A technical problem to be solved by the present invention is that the gears of the rotary disc type roasting furnace in the prior art are easily deformed at a higher roasting temperature, and the dust in the roasting furnace is easily stuck in the gear gap during operation, so that the pinion cannot be connected with the The internal gears are completely meshed, and the motor cannot drive the turntable to rotate through the gear meshing mechanism, so a turntable heating device that does not use a gear mechanism and can operate in a high-temperature and dusty environment is proposed;

Abstract

The invention discloses a rotary disc heating device for drying or pyrolyzing coal. The rotary disc heating device comprises a rotary disc, a feed port, a heating component, a plurality of rotating wheels, an annular track, a rotating shaft and a top cover, wherein the feed port is formed in the rotary disc; the heating component is used for heating a material in the rotary disc; the rotating wheels are connected with a motor; the motor is used for driving the rotating wheels to rotate; the annular track is arranged at the bottom of the rotary disc; the rotating wheels are fixedly arranged below the annular track along the annular track; the annular track is suitable for sliding along the rotating wheels and driving the rotary disc to rotate; the rotating shaft is arranged in the center of the rotary disc; the top cover is arranged above the rotary disc. The rotary disc heating device has the advantages of high stability, large loading capacity and strong environmental adaptability, and is more suitable for being applied to a drying or pyrolysis process of the coal.

Description

technical field [0001] The invention relates to a rotary heating device for drying or pyrolyzing coal materials, belonging to the technical field of drying or pyrolysis equipment. Background technique [0002] In the coal industry, it is generally necessary to dry the mined raw coal to remove moisture and volatile solvents in the raw coal to obtain usable fuel coal, or to further carbonize and pyrolyze the dried fuel coal to obtain products such as coal, coal tar, and gas. Therefore, drying and dry distillation pyrolysis are indispensable operating units in the coal industry. [0003] The drying and dry distillation pyrolysis process of coal generally all adopts the rotary disc heating device to carry out, discloses a kind of multifunctional rotary disc drier as Chinese patent document CN2807163Y, and it comprises furnace body, and the furnace body is provided with plane rotary disc, and above the plane rotary disc is provided with quantitative Conveyor and material hopper,...
