Embodiment Construction

[0013] The present invention will be further described below in conjunction with all accompanying drawings. The preferred embodiment of the present invention is: the roller kiln kiln wall structure described in this embodiment, the main body of the kiln wall is made of JM26 mullite 1 and low iron high aluminum It is made of bricks 2, of which, JM26 mullite 1 is located inside the kiln wall; the outside of low-iron and high-alumina brick 2 is successively covered with zirconium-containing cotton blanket 3 with a thickness of 20mm, and high-purity cotton blanket 4 with a thickness of 20mm , 60mm-thick high-purity fiber cotton board 5, 30mm-thick nanometer board 6, and 30mm-thick aluminum silicate cotton board 7 to form an insulating cotton layer; the total thickness of the insulating cotton layer is 160mm, which is lower than the original kiln wall up to 60mm. The total reduction of the two kiln walls is 120mm. After analyzing the thermal insulation effect and cost comparison, i...

Abstract

The present invention provides a novel roller kiln wall structure. A kiln wall body is built with JM26 mullite and low-iron high-aluminum bricks, wherein the JM26 mullite is arranged on the inner side of a kiln wall; the outer side of the low-iron high-aluminum bricks is coated with an insulation cotton layer formed with a zirconium-containing cotton blanket, a high-purity cotton blanket, a high-purity fiber cotton board, a nano board and a aluminum silicate cotton board; and the zirconium-containing cotton blanket, the high-purity cotton blanket, the high-purity fiber cotton board, the nano board and the aluminum silicate cotton board are coated on the outer side of the low-iron high-aluminum bricks in sequence. By adopting the scheme, a kiln has a more stable brick structure, the product quality is greatly improved, and the building cost of the kiln is reduced.

Description

technical field [0001] The present invention relates to the technical field of roller kiln masonry, in particular to a novel roller kiln wall structure. Background technique [0002] At present, the inner width of the ceramic kiln roller kiln is getting bigger and bigger, which makes the kiln frame wider and wider, and the rollers are getting longer and longer. The ensuing problem is that the bottom beam of the frame bends and the bottom of the kiln sinks, and the rollers are easy to bend. , thus making the brick walking confusing. In order to solve the above problems, under the premise of ensuring the inner width of the kiln, it is necessary to improve the kiln wall structure and reduce the thickness of the kiln wall. The actual thermal measurement found that under normal use, the heating temperature of the inner brick is about 1200 °C, while the heating temperature of the outer brick is about 1000 °C. If double-layer JM26 mullite is used for masonry, the masonry cost will...
