Turnplate heating device used for drying or pyrolyzing coal material

Abstract

The invention discloses a turnplate heating device used for drying or pyrolyzing a coal material. The turnplate heating device comprises a turnplate, a feeding port, a heating part used for heating a material in the turnplate, multiple runners connected with motors, an annular rail arranged at the bottom of the turnplate, a rotating shaft arranged at the center of the turnplate, and a top cover arranged above the turnplate, the feeding port and the heating part are arranged on the turnplate, the motors are used for driving the runners to rotate, the runners are fixedly arranged below the annular rail along the circumference of the annular rail, and the annular rail is suitable for sliding along the runners and driving the turnplate to rotate. The turnplate heating device has the advantages of high stability, large loading capacity and high environmental suitability and is more suitable for being applied to drying or pyrolyzing processes of the coal material.

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,...

AI Technical Summary

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;
