The invention belongs to the technical field of
oil shale processing. The invention particularly relates to a
dry distillation device for
oil shale processing. The problem that in the prior art, the
dry distillation effect on
oil shale is poor is solved. The following scheme is proposed: the device comprises a
dry distillation kettle, wherein a feeding
pipe is arranged at the top of the dry
distillation kettle; filter screen plates are arranged at the bottom in the dry
distillation kettle; air inlet pipes and an air outlet
pipe are respectively arranged at parts, below and above the filter screen plate, of the dry
distillation kettle; a water bath shell wraps a part, located at the tops of the filter screen plates, of the outer wall of the dry distillation kettle, the inner wall of the drydistillation kettle is of a square structure, the inclined filter screen plates are fixed to the bottoms of the inner walls of the two sides of the dry distillation kettle, the filter screen plates incline downwards towards the side away from the inner wall of the dry distillation kettle, and a vibrating screen is connected to the bottom end between the two filter screen plates through torsionalsprings. The air inlet pipes are arranged on the two sides of a
bearing surface, crushed
solid components on the
bearing surface are screened out from the middle position through a vibrating screen, and the situation that air circulation is affected due to the fact that meshes of the whole
bearing surface are blocked is avoided.
