Abstract
The utility model discloses the novel rotary kiln that a kind of third gear supports ultrashort kiln body, including：Rotary kiln kiln body, pedestal and support device；52~55m, a diameter of 4.6~5m of wherein described rotary kiln body are the rotary furnace that draw ratio is less than 13；The quantity of the pedestal and support device is all three, and entire rotary kiln kiln body is fixed on by three groups of support devices on three pedestals.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 is super
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 only constantly carries out technological innovation, improves product quality, reduces energy consumption, existing cement production enterprise could be caused to obtain
Obtain survival and development for a long time.And the place that the enterprise of many low outputs, high energy consumption is limited by original production line limits and often
It advises financial pressure huge caused by transformation and faces 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, the purpose for reducing 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 known 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 using two grades of supports, and long kiln is supported using third gear, and the requirement to lower 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 excessively high.
Invention content
The present invention is called for current present situation, response country for the energy-saving and emission-reduction of building material industry, provides 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 the income of bigger.
To achieve these goals, the present invention uses following technical scheme：A kind of third gear supports novel time of ultrashort kiln body
Rotary kiln, including：Rotary kiln kiln body, pedestal and support device；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 pedestal and support device is all three, and entire rotary kiln kiln body passes through three groups
Support device is fixed on three pedestals.
Further, support device includes wheel belt, support roller and shelves wheel.
Further, three pedestals are located at turn around kiln hood, middle part and the kiln tail of kiln kiln body respectively, two-by-two between pedestal away from
From for 15~20m.
Further, rotary kiln kiln body is additionally provided with main motor and speed reducer, and the main motor and speed reducer are arranged on kiln
Rotary kiln kiln body is connected on the pedestal of head position and rotary kiln kiln body is driven 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 replaced, 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 whole heat consumption, while the activity of free CaO is fully utilized, ripe
The C3S contents of material increase, and so as to improve clinker strength, improve clinker grindability.
The application rotary kiln body weight, which compares the conventional long kiln of third gear, will reduce by 10%, 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 entire production system reduces the power consumption of wind turbine.
For the application third gear rotary furnace since 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, reduces the recycling of clinker dust in kiln, improves unit volume
Yield.
The application is suitable for 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%.
