At present, a kiln wall lining of a high-temperature firing tunnel kiln is built by refractory bricks, and the building of mortar joints is a key problem influencing the stability and heat leakage of a wall body; moreover, the expansion with heat and contraction with cold of the refractory brick body and the mortar joint mortar are different, so that cracks are easy to appear in the brick joints, and meanwhile, the adhesive mortar material between the brick joints can be scattered outwards, so that the outward permeation and leakage of a high-temperature heat source in the kiln can not be blocked, the heat dissipation loss of the kiln is large, the sintering temperature of a kiln cavity is unstable, and the heat efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that an ultra-high temperature tunnel kiln body structure is provided to the aforesaid that exists to prior art is not enough, the brick cohesion is strong not only built by laying bricks or stones to the kiln wall, and the kiln wall is firm, can effectively prevent heat energy leakage moreover, and the kiln thermal efficiency is high.

In order to solve the technical problem, the ultra-high temperature tunnel kiln body structure comprises kiln wall refractory bricks for building a kiln body, wherein clamping grooves are formed in building surfaces of four sides of each kiln wall refractory brick; inlay in the resistant firebrick's of double-phase adjacent kiln wall masonry seam and be equipped with hasp structure, this hasp structure includes two lock cardboard and the cartridge strip that sets up mutually back to the back, is provided with the lock draw-in groove of indent on this lock cardboard, the lock draw-in groove of lock cardboard and the mutual joint in the joint groove of close wall refractory wall, the cartridge strip cartridge is between two lock cardboard that back to the back set up.

In the structure, because the four side surfaces of the kiln wall refractory bricks are mutually connected through the locking structure embedded in the masonry joint, the adjacent refractory bricks are mutually clamped by the locking and clamping plates of the locking and clamping structure, on one hand, the two refractory bricks are firmly locked into a whole by the locking and clamping plates, the mutual binding force of the kiln wall refractory bricks is greatly improved, on the other hand, the locking and clamping plates for connection can be made of the same or similar materials with the refractory bricks, the locking and clamping plates and the refractory bricks have almost the same thermal expansion coefficient, the occurrence of brick joint cracks is avoided, the kiln wall is more stable, and the service life is long. And the locking clamping plate structure is embedded in the brick joints of two adjacent refractory bricks, and the locking clamping plates in the locking structure are arranged perpendicular to the brick joints, so that the leakage of heat energy in the kiln along the brick joints is effectively blocked, the firing temperature in the kiln can be stabilized, the firing quality of refractory materials is improved, the heat energy loss of the kiln is effectively avoided, the heat efficiency of the kiln is improved, and the heat energy is saved. Still because the hasp structure has included the lock cardboard and the cartridge strip that back of the body set up mutually, as long as with lock cardboard installation to the joint groove in, and the cartridge strip is gone up in the cartridge between the lock cardboard of double-phase back of the body and the connection installation of building bricks can be accomplished fast, can realize the wall body and build by laying bricks or stones without the clay between resistant firebrick, fundamentally has avoided the brick joint fracture and the expansion that the brick joint expend with heat and contract with cold that different brick body materials and bonding agent formed leads to, block the outward infiltration of heat energy along the brick joint and the route of colluding, higher heat utilization rate and thermal efficiency have, both practice thrift the brick joint binder, can realize the quick building by laying bricks or stones of kiln wall again, it is more convenient to construct, effectively shorten construction period and construction cost.

In a preferred embodiment of the utility model, the clamping groove on the masonry surface of the refractory brick of the kiln wall is a T-shaped groove; the lock clamping groove on the lock clamping plate is a rectangular groove, and the shape of the clamping groove is identical to that of the lock clamping groove. The inserting strip is a strip regular hexahedron. The manufacture of the refractory bricks and the locking plate is convenient.

The utility model discloses a further embodiment, all be provided with the hasp structure on the refractory brick's of kiln wall four sides masonry face. The kiln wall refractory brick is a regular hexahedral fused corundum casting refractory brick. The high-temperature resistant kiln has extremely high-temperature resistance, the kiln body is more stable, and heat energy leakage is effectively blocked.
