Abstract
The utility model relates to a material raising plate used for a rotary kiln. The utility model relates to a rotary kiln used for baking materials, in particular to a material raising plate which is arranged at the end of a lime kiln. The utility model is characterized in that: the material raising plate is a vertical angle plate the cross section of which takes the type of a rectangular crutch, and fixed through holes are arranged on a crutch handgrip end flat plate of the material raising plate. The utility model is a novel special type abrasion resistant and high-temperature resistant material raising plate which is arranged at the end of the lime kiln, and has the advantages of greatly improvement of dissolution rate of powder and fine materials in the kiln, capability of reducing inlet temperature of an electric dust collection, improvement of thermal utilization factor of the rotary kiln, realization of an aim of reducing energy consumption, capability of saving water scrubbing and screening flows of limestones and large practical application value.
Description
Technical field
A kind of lifting blade that is used for rotary kiln relates to a kind of material that is used for and fires rotary kiln, particularly the lifting blade of limekiln kiln tail.
Background technology
The rotary kiln lime calcining is strict to limestone granularity, requires: 15mm≤limestone granularity≤50mm; And require lime stone is sieved and washes.Do not contain a large amount of powder, thin material (limestone granularity≤15mm) in the limestone mine through screening and washing; And because the lime stone quality is crisp, in the belt course of conveying, reach the further efflorescence of lime stone in the kiln operation process, cause to have a large amount of powder microlith lime stones in the kiln.In the kiln operation process, owing to following reason, bulk materials always concentrates on the surface of material bed, and powder, thin material are wrapped, accumulate in material bed bottom, can not fully mix with unclassified stores at the powder of bed of material bottom, thin material, heat-exchange capacity is poor, makes powder, thin material resolution ratio very low, causes the whole resolution ratio of kiln sodalime low.Its main cause comprises: (1) along with the rotation of kiln, coarsegrain material itself has sieving actoion to the small grain size material; (2) the coarsegrain material is different with small grain size nature stocking angle.Coarsegrain material nature stocking angle is big, and small grain size material nature stocking angle is little; (3) frictional force difference between the material of different grain size, and coarsegrain material rollability is strong, between bulk materials and the material bed slip is arranged.
In process of production, the limekiln kiln end temperature up to 1000 ℃ about, powder in the limekiln, thin material (granularity≤15mm), under of the flue gas effect of kiln tail, just can reach the decomposition purpose up to 850～1100 ℃.Improve limekiln sintering lime quality, particularly can significantly improve the limekiln agglomerated powder, thin material ability is crucial.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, provide a kind of and can make effectively that material can fully mix in the kiln, heat exchange, make the powder limekiln in, thin material (granularity≤15mm) be issued to the lifting blade that the decomposition purpose is used for rotary kiln in of the flue gas effect of kiln tail up to 850～1100 ℃.
The utility model by the following technical solutions.
A kind of lifting blade that is used for rotary kiln is characterized in that this lifting blade is that section is the vertical gusset that the right angle " turns " type, has fixed via " turning " of lifting blade on the plate holding level with both hands.
A kind of lifting blade that is used for rotary kiln of the present utility model, lifting blade is with vertical at rotary kiln wall and along the coaxial setting of rotary kiln axle, and lifting blade is polylith when using, and axially evenly distributes at rotary kiln, and setting radially interlaces.
Of the present utility model at limekiln kiln tail increase lifting blade, force material heat exchange in the kiln, make powder in the kiln, thin material under the effect of lifting blade and other material fully mix, the kiln tail up to 1000 ℃ of left and right sides action of high temperature under, make the interior powder of kiln, microlith lime stone just finish decomposable process, improve powder in the kiln, thin material resolution ratio thereby reach at the kiln tail.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation that lifting blade of the present utility model and rotary kiln connect.
The specific embodiment
A kind of lifting blade that is used for rotary kiln, this lifting blade are that section is the vertical gusset 1 that the right angle " turns " type, have fixed via 3 " turning " of lifting blade on the plate 2 holding level with both hands.
Embodiment
The design lifting blade is of a size of 800 * 550mm, is carbon back composite ceramic material, bending strength 145MPa.Be fixed on the cylindrical shell with screw.Limekiln design filling rate is 10%～15%, and theoretical calculating thickness of feed layer is 600mm.In the actual production now, the limekiln yields poorly, kiln speed is fast, the bed of material is thinner, and thickness is about 300mm, and lifting blade is unsuitable too high, otherwise can further increase material efflorescence in the kiln, so 300mm gets final product according to the high kiln discharge liner of actual conditions lifting blade, the high 250mm of kiln tail liner tile is so select the lifting blade of 800 * 550mm for use.
Lifting blade is fixed on kiln wall 5 with bolt 4, for building the refractory material 6 of refractory brick or pouring material, during maintenance refractory masses is tripped out on the kiln wall, boring screw is fixedly behind the lifting blade on the cylindrical shell, cover the lifting blade bottom with refractory material again and get final product, it is simple to construct.
In kiln Caudad kiln hood extends 30m, lifting blade is installed, 8 lifting blades are installed weekly in the kiln, divide equally circumference, different parts arranged in dislocation, be separated by between a week and the week 200mm, totally 240 lifting blades.Kiln tail feed compartment temperature is about 1000 ℃, begins in the 30m from the kiln tail, and mean temperature can satisfy the requirement of decomposed powder, material fully more than 1000 ℃.
Claims (1)
1. a lifting blade that is used for rotary kiln is characterized in that this lifting blade is that section is the vertical gusset that the right angle " turns " type, has fixed via " turning " of lifting blade on the plate holding level with both hands.
