Abstract

The utility model discloses a high temperature kiln with an integrated structure which comprises kiln walls (5), a kiln top (4), a kiln car (6) and a kiln door (10). The kiln walls (5) are built by kiln wall bricks (1) with convex platforms and grooves; the kiln top (4) is built by skew bricks (2) and thickened kiln top bricks (3). The convex platforms and the grooves allow the kiln walls (5) and the kiln top (4) to be closely linked, the reverse thrust of the arch top can effectively avoid the kiln walls (5) inclining toward inside a kiln freeboard; the increase of the thickness and the taper of the kiln top bricks (3) can effectively avoid the balloting and falling pieces of the kiln top bricks. The kiln door (10) is built by kiln door bricks (8) with convex platforms and grooves, kiln door bayonet bricks (7) and kiln door wall bricks (9). The close connection of the convex platforms and grooves and the bayonet bricks as well as the reverse action of the kiln wall when the door is closed can effectively avoid kiln door inclining toward the inside the kiln freeboard. The utility model allows the kiln body to form a whole by the design optimization to each part of bricks, thereby prolonging the service life of the kiln liner and improving the operation rate of the kiln furnace.

Description

Structure-integrated high temperature kiln

Technical field

The utility model relates to a kind of inorganic non-metallic field high temperature kiln, relates in particular to a kind of structure-integrated high temperature kiln of being made up of Yao Qiang, Yao Ding, kiln car and wicket.

Background technology

In inorganic non-metallic (pottery, refractory material etc.) field,, use Thermal Equipment for goods burn till---the high temperature kiln.Present modal Thermal Equipment has kilns such as tunnel cave, shuttle kiln.Mostly be planar design because of building the used refractory material of kiln body by laying bricks or stones, usually exist kiln body, wicket after using after a while, because of the contraction of refractory material and the influence of expanding with heat and contract with cold, the phenomenon that kiln wall, wicket tilt occurs in the kiln thorax, thereby influence the overall structure and normal use of kiln body.The maintenance of most kiln bodies all because of kiln wall, wicket tilt in burner hearth seriously, is done something against one's will.Because of kiln expenditure of construction costliness, thereby cause great waste, and have a strong impact on the normal operation of production, reduced production efficiency.

The utility model content

The technical problem that the utility model solves is a kind of structure-integrated high temperature kiln of design-build, and it can not only effectively prolong the service life of kiln lining material, and can improve the utilization rate of kiln, thereby saves the cost of overhaul greatly, improves operation rate.

In order to solve the problems of the technologies described above, structure-integrated high temperature kiln of the present utility model, kiln wall brick and wicket brick by band boss and groove, and with the kiln wall brick be complementary the band boss skew block, thickening also has the ceiling brick of degree (than original thickening 30～60%) slightly, and wicket bayonet socket brick is built by laying bricks or stones through science and formed.

Kiln wall brick with band boss and groove; skew block of band boss is complementary with it; the purpose that replaces original plane brick is: in the past; with the brick kiln body of building in plane after using after a while; the kiln wall that skew block is following because of the influence that is subjected to refractory material to shrink and expand with heat and contract with cold, can tilt in burner hearth usually; until the normal running that influences kiln, so the time between overhauls(TBO) is shorter.Adopt newly-designed kiln wall brick and skew block,, whole Yao Qiang, Yao Ding are become one, can effectively avoid the inclination of kiln wall, thereby prolong the service life of kiln, reduce recondition expense greatly, and improve the kiln running rate by the boss and the groove of brick body.

The purpose of thickening ceiling brick is: increase the degree slightly of monolithic brick, to reduce ceiling brick through after repeatedly using, fall the possibility of piece or lot because of local fracture.Simultaneously because of having reduced the piece number of ceiling brick, thereby accelerate the construction speed of kiln, and increased the imporosity of kiln body, thereby reduced heat-energy losses.

With the wicket brick of band boss groove, and, wicket and wicket wall are combined as a whole, both can utilize the tight structure of emboss pit, also can utilize and close behind the door that the reaction force of wicket bayonet socket brick and kiln wall prevents the inclination of fire door in burner hearth by wicket bayonet socket brick.Thereby improve the service life of fire door.

The specific embodiment

Structure-integrated high temperature kiln liner high temperature lightweight refracrory shown in Figure 1 is built the kiln wall by laying bricks or stones by the kiln wall brick 1 of band boss groove, by the skew block 2 of band boss with increased the ceiling brick 3 that the monolithic brick spends slightly and build the kiln top by laying bricks or stones, the width of kiln wall brick boss and groove is the 1/4-1/5 of kiln wall brick length overall, dark is 5-10mm, the groove of the boss of skew block and kiln wall brick is complementary, thereby structurally forms the tight kiln body that interlocks layer by layer.Avoided the lot of inclination in burner hearth in use of kiln wall and ceiling brick to fall piece.

Structure-integrated high temperature kiln wicket liner high temperature lightweight refracrory shown in Figure 5 is built wicket by laying bricks or stones by wicket brick 8, the wicket bayonet socket brick 7 of band boss groove; The boss on the wicket brick and the width of groove are the 1/4-1/5 of wicket brick length overall, are 5-10mm deeply, and the bayonet socket width of wicket bayonet socket brick 7 is 50-100mm, builds the wicket wall by laying bricks or stones by wicket wall brick 9.Utilize the boss groove of wicket brick and the bayonet socket of wicket bayonet socket brick that wicket and wicket wall are become one; Utilize the reaction force of kiln wall at closing time, can effectively avoid the inclination of wicket to burner hearth.
