Abstract
The invention discloses a spiral rotary kiln. The spiral rotary kiln is characterized in that spiral heating tubes (7) are used to define a kiln body framework (1) of the rotary kiln; a lining (10), a heat insulating layer (6), a heat insulation layer (8) and an outer protecting plate (9) are additionally arranged on the kiln body framework (1) according to the requirements; axial tubes (2) are arranged at two ends of the kiln body framework of the rotary kiln defined by using the spiral heating tubes (7); the axes of the axial tubes (2) are superposed with the axis of the kiln body framework of the rotary kiln defined by using the spiral heating tubes (7).
Description
Technical field
Kiln, particularly rotary kiln.
Background technology
As everyone knows, rotary kiln is widely used in the technical process such as raw-material drying, sintering and calcining.The mode of heating of rotary kiln is: fuel is sprayed into kiln chamber inner combustion from one end of kiln, and flue gas is discharged from the other end of kiln, thus by the drying of reverse in kiln thorax and capable heating material, sintering or calcining.
But above-mentioned traditional rotary kiln has it to be difficult to the shortcoming overcome, one is the flue gas and material mixed convection in kiln thorax that burn, very easily causes the pollution of material, brings a large amount of granular materials into chimney simultaneously, cause waste and environmental pollution; Two is that the globality of inner lining of kiln is very poor, easily causes anchoring piece to rupture and inner lining material comes off.
Summary of the invention
For solving the problem, the invention provides a kind of spiral rotary kiln, it is characterized in that: the kiln body skeleton surrounding rotary kiln with helical heating pipe (7), and as required for it installs liner (10), heat-insulation layer (6), (8) and outer casing (9) additional.
Above-mentioned helical heating pipe (7) can be electric heating tube or gas heating pipe.
The kiln body skeleton two ends of the rotary kiln surrounded at above-mentioned helical heating pipe (7) are provided with axle center pipe (2), the kiln body skeleton axis coinciding of its axle center and the rotary kiln surrounded with helical heating pipe (7).
According to the difference of heated material and heating-up temperature, the material of above-mentioned helical heating pipe (7) can select heat resisting steel or refractory material or refractory ceramics.
When the material of above-mentioned helical heating pipe (7) be refractory material or refractory ceramics time, outside the kiln body skeleton that can form at it, get up with resistant to elevated temperatures fibrous material (5) anchor ear, to strengthen the overall construction intensity of rotary kiln.
Above-mentioned resistant to elevated temperatures fibrous material (5) is carbon cloth.
In order to inner lining material (10) is securely fixed on the inwall of kiln thorax (3), the pitch between above-mentioned helical heating pipe (7) can be made to be greater than the caliber of helical heating pipe (7), namely between helical heating pipe (7), to leave gap; Helical heating pipe (7) is wrapped up by above-mentioned gap by inner lining material (10), and is linked to be entirety.
The usefulness of this spiral rotary kiln is: 1, can effectively avoid material by gas pollution; 2, bulk strength is high, long service life; 3, liner is firm, difficult drop-off.
