Abstract
The invention discloses the novel rotary kiln that a kind of third gear supports ultrashort kiln body, including：Rotary kiln kiln body, base and support meanss；52~55m, a diameter of 4.6~5m of wherein described rotary kiln body, it is the rotary furnace that draw ratio is less than 13；The quantity of the base and support meanss is all three, and whole rotary kiln kiln body is fixed on three bases by three groups of support meanss.The application third gear rotary furnace is small due to draw ratio, heat radiation, convection current, conducting effect in kiln will be better than the long kiln of conventional third gear, so as to which kiln gas speed is less than conventional rotary kiln, reduce the recycling of clinker dust in kiln, unit volume yield is improved, reduces power consumption, the heat consumption of system.
Description
Technical field
The invention belongs to field of building equipment, and in particular to a kind of third gear support that production consumption reduction is carried for cement producing line surpasses
The novel rotary kiln of rotary furnace body.
Background technology
With deepening continuously for Industry Structure adjustment, the energy-saving cement industry that has become develops new promotion
Power, technological innovation is only constantly carried out, product quality is improved, reduces energy consumption, existing cement production enterprise could be caused to obtain
Obtain survival and development for a long time.And much yield poorly, the enterprise of high energy consumption is limited by the place of original production line and limited and often
Advise financial pressure huge caused by transformation and face the difficult situation being eliminated.It is a kind of to carry production consumption reduction for cement producing line
Novel rotary kiln be exactly in this context, on the basis of existing equipment, enterprise to be realized with alap cost
Improve production capacity, reduce the purpose of energy consumption.
For cement rotary kiln, commonly referred to as long kilns of draw ratio (rotary kiln length/rotary kiln diameter) L/D more than 13,
Draw ratio L/D is referred to as rotary furnace between 10-13, and current long kiln, rotary furnace have utilization in each cement plant, respectively there is excellent lack.It is and short
Kiln is all to be supported using two grades of supports, long kiln using third gear, and the requirement to be lowered consumption with national energy-saving deepens constantly, many cement enterprises
Industry will improve its production efficiency, but the long kiln of third gear that most of enterprise uses by carrying production consumption reduction, be limited to place and limited, such as
Production consumption reduction is carried, primary producing line is all almost pushed over into reconstruction, improvement cost is too high.
The content of the invention
The present invention is directed to current present situation, and response country calls for the energy-saving and emission-reduction of building material industry, there is provided a kind of third gear
The novel rotary kiln of ultrashort kiln body is supported, each cement production enterprise can be allowed to pay smaller cost, realizes bigger income.
To achieve these goals, the present invention uses following technical scheme：A kind of third gear supports new time of ultrashort kiln body
Rotary kiln, including：Rotary kiln kiln body, base and support meanss；The length of wherein described rotary kiln body is 52~55m, a diameter of
4.6~5m, draw ratio are less than 13；The quantity of the base and support meanss is all three, and whole rotary kiln kiln body passes through three groups
Support meanss are fixed on three bases.
Further, support meanss include wheel belt, support roller and shelves wheel.
Further, three bases are located at turn around kiln hood, middle part and the kiln tail of kiln kiln body respectively, two-by-two between base away from
From for 15~20m.
Further, rotary kiln kiln body is additionally provided with main motor and reductor, and the main motor and reductor are arranged on kiln
Rotary kiln kiln body is connected on the base of head position and drives rotary kiln kiln body to rotate.
The rotary kiln device that the application provides can be used for replacing the original rotary kiln device of cement producing line.Rotary kiln device
It can be upgraded on the basis of the long kiln plant of original third gear, be changed, rotary kiln device does not influence primary producing line kiln hood, kiln tail
Arrangement and interface.
The maximum (top) speed of the application rotary kiln reduces the residence time of raw material intermediate zone in kiln up to 5.5r/min,
So that raw material enter clinkering zone as early as possible, so as to reduce overall heat consumption, while the activity of free CaO is fully utilized, ripe
The C3S contents increase of material, so as to improve clinker strength, improves clinker grindability.
The application rotary kiln body weight will reduce by 10% compared to the long kiln of conventional third gear, simultaneously because the diameter of rotary furnace is greater than
Conventional rotary kiln, therefore kiln inner section product is greater than conventional rotary kiln, so as to reduce the resistance of kiln gas flowing, and then subtracts
The air resistance of small whole production system, reduce the power consumption of blower fan.
For the application third gear rotary furnace because draw ratio is small, heat radiation, convection current, conducting effect in kiln will be better than conventional revolution
Kiln, so as to which kiln gas speed is less than conventional rotary kiln, the recycling of clinker dust in kiln is reduced, improves unit volume
Yield.
The application is applied to the former enterprise using the long kiln of third gear and carries out upgrading, can help the transformation of enterprise backward in technique
Investment cost reduces more than 30%.
Brief description of the drawings
Fig. 1 is the structural representation of rotary kiln of the embodiment of the present invention.
Embodiment
In order to be better understood from and illustrate the present invention, below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 is the novel rotary kiln that a kind of third gear supports ultrashort kiln body, and rotary kiln includes rotary kiln kiln body, base and support
Device.
Wherein the length of rotary kiln kiln body is 52m, a diameter of 4.6m.The quantity of base and support meanss is all three, whole
Individual rotary kiln kiln body is fixed on three bases by three groups of support meanss.
Support meanss include wheel belt, support roller and shelves wheel.Three bases are located at turn around kiln hood, middle part and the kiln of kiln kiln body respectively
Tail, two-by-two the distance between base be.
Rotary kiln kiln body is additionally provided with main motor and reductor, and main motor and reductor are arranged on the base at kiln hood position
Connection rotary kiln kiln body simultaneously drives rotary kiln kiln body to rotate.
