Technical field
This utility model is related to inner liner of rotary kiln structure, more particularly to a kind of to have augmentation of heat transfer, drying and burn effect
Rotary kiln device.
Background technology
Rotary kiln is widely used in the technical processs such as material calcining, is capable of achieving large-scale continuous production, and motility is big, product
Steady quality.Rotary kiln feed end is high, and exhaust end is low, is rotated with the rotating speed of 1~3r/min, and material is from high-end to the fortune of low side
Disorder of internal organs completes decomposes.Due to the rotation of kiln in rotary kiln, material particles are produced under frictional force, gravity and centrifugal action
Raw motion, the form rolling for having transverse section of motion and the axially-movable formed due to the gradient of kiln.Wherein on transverse section
Material movement state different with material form point have according to the rotating speed of kiln：Downglide motion, motion of collapsing is turned over, motion is tumbled, is left fortune
The form such as dynamic.
The motion of material is mainly based on downglide motion in slow-speed of revolution rotary kiln.Because rotating speed is low, rub between material and kiln lining
Wipe power less, be not enough to drive improving material or hoisting depth very little, constantly produce under material gravity effect move on a small amount of and
Slide, and relative static conditions are between material particles.In addition, granular material can produce automatic sieving in motor process
Phenomenon, causes size particles material skewness on transverse section, bulky grain integrated distribution to concentrate on thing in surface, little particle
The center of the bed of material.Under this state, top layer material is constantly exposed among air-flow, and direct right between materials inside and air-flow
Spread heat and be substantially at halted state, the conduction heat transfer of radiant heat transfer and kiln lining to material is also only limited to the surface layer of material.This
Planting phenomenon may cause top layer material burning, materials inside underburnt to have a strong impact on the quality of product, the thermal efficiency and heat utilization efficiency
It is low, energy waste is caused, also it is unfavorable for the control of every technical indicator of kiln.
Utility model content
For the problems referred to above, the purpose of this utility model is that design is a kind of to be had augmentation of heat transfer, drying and burns effect
Rotary kiln device, motion morphology of the material in kiln can be improved, improve the uniformity that material is contacted with gaseous medium, improve
Heat exchange and firing efficiency, improve heat utilization efficiency, and reducing energy consumption creates considerable economic benefit.
In order to achieve the above object, this utility model employs the following technical solutions realization：
It is a kind of with augmentation of heat transfer, drying and burn effect rotary kiln device, along rotary kiln axis direction, the device by
It is brick that feeding end, bright finish+convex surface brick masonry section, whole convex surface brick masonry sections, bright finish+spiral prominence face brick build section, whole bright finish by laying bricks or stones
Build section, discharge end and be sequentially connected composition.
The bright finish+convex surface brick masonry section includes some equally distributed convex surface brick material lifting belts on kiln section.
Whole convex surface brick masonry sections are constituted by convex surface brick, and convex surface brick builds section formation collet by laying bricks or stones at this.
The bright finish+spiral prominence face brick builds section by laying bricks or stones including some spiral type liftings built by laying bricks or stones by the dislocation of convex surface brick
Band, the spiral extension direction of spiral type material lifting belt is consistent with the direction of rotation of rotary kiln.
Compared with prior art, the beneficial effects of the utility model are：
This utility model builds the effect of section by laying bricks or stones by each, changes the motion morphology of material in kiln, significantly improves calcining equal
Even property.Specifically action principle is：(1) in bright finish+convex surface brick masonry section, enter kiln material and turn with kiln body in the presence of material lifting belt
Dynamic, convex surface brick can hinder to expect that bed bottoms material glides, and material is forced to be lifted；When material bed upper materials occur under gravity
Lower backwardness, lower floor material continues to be promoted to certain altitude by material lifting belt and just falls, and realizes upper materials and lower floor's material
Relative displacement, plays rollover effect；(2) whole convex surface brick masonry sections, by convex surface brick collet is formed, and extends material in preheating section
The time of staying, improve material pre-heat effect；(3) build section by laying bricks or stones in bright finish+spiral prominence face brick, screw type material lifting belt bearing of trend with
Kiln body rotation direction is consistent, plays the effect that continuance lifting overturns material.By above-mentioned design, material can be improved in kiln
Motion morphology, improves the uniformity that material is contacted with gaseous medium, improves heat exchange and firing efficiency, improves heat utilization efficiency, reduces
Energy consumption, creates considerable economic benefit.The device can be widely applied to various materials, such as solid waste, especially
It is the technical processs such as the burning disposal of hazardous waste.
