The utility model provides a quick dismounting and mounting heating device for a belt dryer, which comprises a
barrel, and fixing plates are correspondingly arranged on two sides of the front surface and the rear surface of the
barrel. The heating base plate, the heating plate and the panel are assembled into an integrated
heating element, the heating
assembly is pulled to slide along the sliding rails, so that the heating
assembly can slide out of the
barrel conveniently, the heating base plate or the heating plate can be repaired and maintained conveniently, the sliding grooves in the insulating blocks on the heating base plate slide along the sliding rails, and the heating
assembly can be conveniently detached. A limiting
plunger is pushed to be inserted into a limiting groove through the elastic force of a spring, so that the heating assembly is limited to complete installation, and then the heating plate is conveniently and rapidly disassembled, assembled and maintained when having a fault, and the heating assembly is driven to move up and down by rotating a lead screw to adjust the height; the panel at the top of the heating plate is attached to the conveying belt, so that the
heat transfer efficiency is improved, and the heating and
drying effects of
powder materials on the conveying belt are improved.
