The invention belongs to the technical field of byproduct industrial salt treatment equipment, and particularly relates to a waste salt
incineration heat preservation furnace body structure. The structure comprises a furnace body. The furnace body comprises a side wall and an upper wall. The side wall sequentially comprises an outer wall layer, a middle heat preservation layer, a partition layer and a
corrosion-resistant layer from outside to inside, wherein the
corrosion-resistant layer is formed by splicing
refractory bricks, a plurality of clamping grooves are formed in the partition layer,a plurality of connecting blocks are connected to the clamping grooves in a sliding manner, fixing grooves are formed in the
refractory bricks, connecting columns are fixed to the connecting blocks,the
refractory bricks are spliced and fixed to the partition layer through the connecting columns, each refractory
brick comprises a layer refractory
brick body and a common refractory
brick body, a sliding groove is formed in each upper-layer refractory brick body, an adjusting block capable of making contact with the upper wall of the furnace body is slidably connected to each sliding groove, the side, facing the interior of the corresponding upper-layer refractory brick body, of each adjusting block is a slope, each upper-layer refractory brick body is provided with a threaded groove whichcommunicates with the corresponding sliding groove, and the threaded grooves are in threaded connection with push rods. According to waste salt
incineration heat preservation furnace body structure, the problem that refractory bricks of an existing incinerator are troublesome to replace can be effectively solved.
