Abstract
The utility model discloses a kind of inner liner of rotary kiln brick, relate to rotary kiln refractory material.A kind of inner liner of rotary kiln brick, the brick of described liner tile is fan-shaped, and what wherein connect with rotary kiln inwall in liner tile slots.The utility model structure is simple, and easy construction, effectively can control the whole and part deformation of kiln liner tile, not easily case accident occur, and has long service life, advantage that cost is low.
Description
Technical field
The utility model relates to rotary kiln refractory material, is specifically related to a kind of inner liner of rotary kiln brick.
Background technology
Rotary kiln, is commonly called as rotary kiln, all has a wide range of applications and play an important role aborning at many industrial circles, is the nucleus equipment of the industry production such as cement, chemical metallurgy, lime.
Rotary kiln is one and constantly rotates and continue to be in the revolving body of high-temperature heating state in production run process, and in the course of the work, in rotary kiln, operating temperature is up to 1200-2000 degree.The kiln body of rotary kiln is generally made up of the kliner coating that steel plate is special refractory brick, castable and skin.Inner liner of rotary kiln refractory brick is as the main material of heat-insulation and heat-preservation, and its quality and life-span directly affect the quality of production that exhibitions wants, energy resource consumption and service life.
Existing rotary kiln body liner generally uses cross section to be trapezoidal or fan-shaped refractory brick, builds by laying bricks or stones or interlocks build by laying bricks or stones along wall circular in kiln body.Because refractory brick itself does not have adhesive force to kiln body inwall, the mutual extruding between brick and brick and displacement is relied on to limit to maintain internal structure, under long-term production ruuning situation, inner lining structure easily occurs, along direction of rotation, overall or local offset occur, refractory brick very easily peels off, therefore optimize and strengthen inner lining structure, extending the liner life-span, improving the important subject that rotary kiln production operational availability is industrial circle technical staff always.
Summary of the invention
The purpose of this utility model is to provide a kind of inner liner of rotary kiln brick.
The utility model is achieved through the following technical solutions:
A kind of inner liner of rotary kiln brick, the brick of described liner tile is fan-shaped, and what wherein connect with rotary kiln inwall in liner tile slots.
Further, described slot cross-section is triangle, circular arc or rectangle.
A kind of inner liner of rotary kiln brick, the brick of described liner tile is trapezoidal, and what wherein connect with rotary kiln inwall in liner tile slots.
Further, described slot cross-section is triangle, circular arc or rectangle.
In use, with liner tile slotting position relative to rotary kiln inwall on the steel that are welded and fixed, the shape of steel and liner tile bottom surface matching form of slotting closes, what cooperation restriction between the two strengthened liner tile and kiln wall agrees with intensity, wherein when slot cross-section is triangle, can weld the angle steel of correspondence, when slot cross-section is circular arc, round steel, welded tube can be welded, when slot cross-section is rectangle, can rectangular tube, square tube etc. be welded.
The utility model structure is simple, and easy construction, effectively can control the whole and part deformation of kiln liner tile, not easily case accident occur, and has long service life, advantage that cost is low.
