Description
Technical field
The utility model belongs to material distributing machine technical field, is related to a kind of orientable cloth of large-scale multifuel combustion lime shaft kiln
Machine.
Background technique
Large-scale multifuel combustion lime shaft kiln is the vertical limekiln for calcined limestone and anthracite (coke) mixed material, with
Lower abbreviation shaft furnace.There are many shaft furnace distributing devices of the prior art, such as swivel elbow distributing device, multi-point distribution device, rotation scroll casing type
Distributing device and the revolving top with reflecting plate etc., their groundwork process is: in advance by a certain percentage by grain under kiln
The lime stone and anthracite of shape are mixed to get mixture, are fed the mixture into the storehouse Yao Ding using elevator, and Yao Ding is equipped in storehouse
The one section or two sections bell for sealing after mixture enters the storehouse Yao Ding, lifts bell by additionaling power, mixture will
It is slippery enter cloth oblique bend pipe or chute in, while tiltedly bend pipe make rotary motion, mixture is sowed in shaft furnace, mixture is broadcast
After spreading, oblique bend pipe stops rotary motion, and bell is fallen, and completes a duty cycle.Defect existing for these distributing devices point
It is not:
1. swivel elbow distributing device: the oblique bend pipe cloth of rotation, so that mixture can only be along certain diameter in shaft furnace
Circumference is sowed, and mixture cannot be made to be uniformly distributed on shaft furnace cross section, and the mixture in shaft furnace forms material ridge along this circumference
Hold together, the out-of-flatness of material face: since the partial size of mixture is inconsistent, big partial size material, which can roll, to be dropped down onto from shaft furnace heart farther place or leans on
At the nearly kiln heart, small particle material can be occupy at circumference, this makes mixed lime stone and anthracite separate or isolate again,
There is the phenomenon that inclined cloth, influence the uniform calcination of shaft furnace, eventually affects the firing rate of lime；
2. multi-point distribution device: multi-point distribution, mixture are put into kiln along different minute of angle heaps several times, when material mixes not
When even, heap enters the anthracite in kiln and is distributed in limestone material in bulk or density unevenness shape, when calcining, it may appear that coal many places
Local temperature is excessively high, coal locates the too low phenomenon of temperature less, this will cause, and limestone calcination is uneven, and appearance is burnt partially, final to influence
To the firing rate of lime.
3. rotating scroll casing type distributing device and the revolving top with reflecting plate: can be by mixture along shaft furnace section when cloth
Certain ring belt is sowed, and there is also the inclined cloth of mixture, anthracites the phenomenon that separating inclined burning again with lime stone, it is final influence calcining and
Lime quality.
Above several distributing devices all have the disadvantage in that burning velocity is fast, and heat loss is big since circumferentially side air quantity is big,
Relative consumption fuel is more, cannot become proportion with batch of material and broadcast cloth, causes edge lime raw burn high and influences whole kiln lime quality, no
Adapt to shaft furnace circumferentially requirement of the side air quantity greater than inner circle air quantity.
