Abstract
The utility model provides a rotary kiln and relates to the improvement of a rotary kiln inner liner structure for material treatment in industries such as chemical engineering and metallurgy building materials. The rotary kiln is characterized in that a material lifting plate which is arranged in the length direction of the kiln and is vertical to an inner liner of the rotary kiln is embedded on the inner liner of the rotary kiln. The rotary kiln has the advantages that because the material lifting plate with the forced heat exchange function is added and adopted in the inner liner of the rotary kiln, the heat exchange effect of materials and high-temperature hot air flows in the kiln is enhanced, the yield of a rotary kiln system is improved, the clinker quality is improved, and the coal consumption of each ton of clinkers is reduced.
Description
Technical field
A kind of rotary kiln relates to a kind of improvement of the inner liner of rotary kiln structure of processing for industry materials such as chemical industry, metallurgical building materials.
Background technology
The rotary kiln that is used for the industry material sintering such as chemical industry, metallurgical building materials, its structure are to be the tubular kiln body that rotates, and material rolls with kiln body rotation direction in tubular kiln body, and in kiln, high temperature hot gas stream contacts with material and adds thermal material.Because the liner inner surface is the level and smooth face of cylinder, thick and heavy bed of material centre can not get heating well all the time, has affected material and has burnt till quality, has limited the further raising of kiln production capacity.
Summary of the invention
The purpose of this utility model is the deficiency that exists for above-mentioned prior art, provides a kind of and can effectively improve material and high temperature hot gas stream heat exchange situation in kiln, and when improving the platform of kiln system, production capacity and clinkersintering quality, reduce ton rotary kiln of grog energy consumption.
The purpose of this utility model is achieved through the following technical solutions.
A kind of rotary kiln is characterized in that being lining with in rotary kiln, be inlaid with along the kiln length direction arrange, the lifting blade vertical with inner liner of rotary kiln.
A kind of rotary kiln of the present utility model is characterized in that described lifting blade is some, circumferentially is equidistantly along rotary kiln, and the kiln length direction is cut apart and the arrangement that is staggered.
A kind of rotary kiln of the present utility model is characterized in that the described lifting blade top vertical with inner liner of rotary kiln and one is connected with to the flap of supplied materials direction bending.
A kind of rotary kiln of the present utility model is characterized in that described flap to the bending of supplied materials direction is that 120 degree are to 140 degree with the angle of the vertical lifting blade of inner liner of rotary kiln.
A kind of rotary kiln of the present utility model owing to increasing the lifting blade that has adopted forced heat-exchanging in inner liner of rotary kiln, has strengthened the heat transfer effect of the interior high temperature hot gas stream of kiln and material, has improved the rotary system production capacity, has improved clinker quality, has reduced the coal consumption of ton grog.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1.
The specific embodiment
A kind of rotary kiln, on the liner 1 of rotary kiln, be inlaid with along the kiln length direction arrange, the lifting blade 2 vertical with inner liner of rotary kiln; Described lifting blade is some, circumferentially is equidistantly along rotary kiln, and the kiln length direction is cut apart and the arrangement that is staggered; Going back one above the described lifting blade vertical with inner liner of rotary kiln is connected with to the flap 3 of supplied materials direction bending; Described angle to the flap of the supplied materials direction lifting blade vertical with inner liner of rotary kiln is that 120 degree are to 140 degree.
Adopt the mounting means of attached extension at the metal lifting blade of rotary kiln, be about to attached the hanging on refractory brick rather than with lifting blade of lifting blade and be arranged on cylindrical shell, when brick inside lining building, lifting blade is embedded in liner.This lifting blade adopts casting heat resistant steel, and its trade mark can be with reference to 1Cr18Ni9Ti.The refractory brick that adheres to embedded lifting blade is fixed on lifting blade in brick liner securely.
During rotary kiln running, material is subjected to stopping of lifting blade, and material is kicked up, and the interior high temperature hot gas stream of kiln is fully contacted with material, has strengthened heat transfer effect.
