Abstract
The utility model discloses a rotary carbon kiln and particularly relates to a calcining zone of a rotary carbon kiln. The calcining zone of the rotary carbon kiln comprises an inner wall of a rotary kiln lining and a material raising zone (3), wherein the inner wall of the rotary kiln lining is built by using precast blocks (8) and a material pouring zone (6), the material raising zone (3) is built on the surface of the inner wall of the rotary kiln lining, and the material raising zone (3) is of an integrated structure formed by connecting material raising blocks (7) end to end and is spirally arranged along the inner surface of the rotary kiln lining. By using the calcining zone of the rotary carbon kiln, materials can be better dispersed, the heat exchange efficiency is increased, the calcining quality is improved, the yield is increased, and the service life of the lining and the maintenance period are prolonged.
Description
Technical field
The utility model relates to a kind of carbon rotary kiln, particularly relates to a kind of carbon rotary kiln burning zone.
Background technology
In recent years, along with the fast development of aluminium electroloysis industry, aluminium anode charcoal piece demand also increases severely thereupon.Calcining petroleum coke equipment generally has two kinds at present, i.e. carbon rotary kiln and can-type calcine furnace.Wherein the advantage of carbon rotary kiln is continued operation, the operating personnel that occupy little space, need are few, construction investment is low, production capacity is large, but it also exists the technical problem that service life is low, maintenance period is short, running rate is lower.
The important role of material lifting belt in burning zone in rotary kiln, in rotary kiln, material is along with the kiln body rotating rises to after certain altitude under the effect of frictional force, under the effect of gravity, the downward landing of material, because the kiln body of rotary kiln has certain angle of inclination, material can not drop on original position, but to low side namely kiln hood direction move a segment distance, fall minimum point, after by liner, drive to be risen again, and then landing forward, so repeatedly.Material lifting belt is material can be taken to higher position, makes material no longer along liner landing, but drops downwards.Can make like this material more disperse, improve calcining effect.
The structure of material lifting belt is with lifting piece, to build into 4～6 material lifting belts that exceed cast charge level 80～100mm building on material strip of burning zone by laying bricks or stones at present, and material lifting belt is arranged along rotary kiln axial direction straight line.The material lifting belt of this structure is point-blank, so material in same material lifting belt, be brought to after certain altitude, drop downwards at one time, larger to the impulsive force of kiln body liner like this, easily liner is caused to damage, reduce liner service life, maintenance period is short, also has the technical problems such as running rate is low simultaneously.
Summary of the invention
The utility model is exactly in order to solve the problems of the technologies described above, and a kind of carbon rotary kiln burning zone providing, it can make material better disperse, and improves heat exchanger effectiveness, improves burning quality, improves output, extends the service life of liner, has extended maintenance period.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
Carbon rotary kiln burning zone, it comprise by prefabricated section with build the inner liner of rotary kiln inwall that material strip builds by laying bricks or stones, the material lifting belt that inner liner of rotary kiln inner wall surface is built by laying bricks or stones, wherein material lifting belt is the overall structure being connected and composed from beginning to end by lifting piece, material lifting belt along inner liner of rotary kiln inner surface twist formula arrange.
Described material lifting belt the best is along inner liner of rotary kiln inner surface, to be contrary spiral form to arrange.
Described inner liner of rotary kiln inner surface circumferencial direction arranges weekly 4～6 helical form material lifting belts.
Described lifting piece exceeds cast material strip 110-120mm.
Owing to adopting said structure, make the utlity model has following advantage and effect.
The utility model arranges carbon rotary kiln burning zone material lifting belt against spiral form, the advantage of arranging is like this:
1, because lifting piece is into contrary screw arrangement, so material is not to drop downwards at one time, but with different levelsly drops downwards, can make like this material better disperse, and improves heat exchanger effectiveness, and then improves burning quality;
2, because contrary helical structure can make the material component state landing of fall apart, reduce the frictional force resistance between material, and then the in the situation that of kiln body same rotational speed, material is moved sooner by kiln Caudad kiln hood, accelerate discharging speed, and then raising output;
3, because material is to drop downwards by different level, rather than the dropping of same time, thereby reduced the impulsive force of material to liner in synchronization, reduce due to the damage of material impact to kiln body liner, extend the service life of liner, extended maintenance period.
