Abstract
The utility model discloses a tunnel kiln for calcining alumina homogenizing materials. The tunnel kiln comprises a preheating zone, a burning zone and a cooling zone, wherein a first nozzle of a kiln body on the burning zone and a second nozzle of the kiln body on the burning zone are arranged in an up-and-down mode. In the tunnel kiln for calcining the alumina homogenizing materials, the two nozzles are changed from being distributed in parallel to being distributed in a staggered mode, and made to be distributed in an up-and-down mode, therefore, temperature difference of the upper portion of a brick pile and the lower portion of the brick pile can be avoided and the stability of product quality is improved. In addition, the length of the preheating zone, the length of the burning zone and the length of the cooling zone are rationalized, energy consumption can be lowered and product output is improved.
Description
Technical field
The utility model relates to a kind of tunnel cave, be specifically related to a kind of calcine alumina tunnel cave.
Background technology
Concern and the approval of part producing use producer have been obtained at present with the method for tunnel cave calcining alumina homogenization material, but want to popularize in an all-round way the technology of tunnel cave calcining alumina homogenization material, also there are many problems, have when particularly producing alumina homogenization material with the existing tunnel kiln that output is little, energy consumption is high, often occur card kiln phenomenon when unstable product quality, production.
The utility model content
Energy consumption height, unstable product quality provided a kind of tunnel cave of calcining alumina homogenization material when the technical problems to be solved in the utility model was tunnel cave production alumina homogenization material, can cut down the consumption of energy the stability of improving the quality of products.
The technical solution of the utility model realizes in the following manner: a kind of tunnel cave of calcining alumina homogenization material, comprise preheating zone, clinkering zone and salband, and first burner and second burner of described clinkering zone place kiln body are arranged above and below.
The length ratio of described preheating zone, clinkering zone and salband is 2:1.5:1.
In the utility model, made two burners into the staggered floor distribution by the parallel distribution of prior art, made two burners distribute one on the other, it is too big to avoid brick to stamp upper and lower temperature difference, has improved the stability of product quality.In addition, the length of preheating zone, clinkering zone and salband is rationalized, can be cut down the consumption of energy, improve product yield.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cross-sectional schematic of clinkering zone place tunnel cave.
The specific embodiment
As shown in drawings, a kind of tunnel cave of calcining alumina homogenization material comprises preheating zone 1, clinkering zone 2 and salband 3, and first burner 4 and second burner 5 of described clinkering zone 2 place's kiln bodies are arranged above and below.
In the prior art, first burner 4 and second burner 5 spray into fuel gas and air by these two burners in kiln on a face, and can make brick stamp upper and lower surface like this has the bigger temperature difference, cause product quality to can not get guaranteeing.The utility model distributes two burners up and down, has reduced the upper and lower temperature difference that brick is stamped as far as possible, has improved the quality of product.
The length ratio of described preheating zone 1, clinkering zone 2 and salband 3 is 2:1.5:1.The length ratio of preheating zone 1, clinkering zone 2 and salband 3 is 1.5:1:1.5 in the prior art, and this structure needs higher energy consumption, adopts after the length ratio of the present utility model, and it is original 2/3rds that energy consumption is reduced to, and also improved output.The utility model not only can be used for producing alumina homogenization material, can also be used to products such as fused mullite, sintering alumina corundum, the U.S. aluminate of sintering.
