Embodiment Construction

[0011] Such as figure 1 As shown, a cement kiln tertiary air pipe elbow includes an outer wall 1 and an inner wall 2, the outer wall 1 and the inner wall 2 are arc-shaped, and at least one bump 3 is provided on the inner wall 2, and the bump 3 3 is a trapezoidal shape, and can also be other square, arc-shaped and other shapes that are easy to process. The effect of the trapezoidal shape is better. The bumps 3 are evenly distributed on the inner wall 2, so that the bumps 3 can evenly withstand the effect of hot air flow , which better protects the service life of the inner wall 2 of the elbow. The metal anchor 4 is arranged in the bump 3. One end of the metal anchor 4 is placed in the bump 3, and the other end is connected to the inner wall 2. It can also be Fixing by other means, using metal anchors for fixing facilitates the disassembly and replacement of the bump 3, which is convenient to use and simple in structure.

Abstract

The invention relates to a tertiary air hose elbow of a cement kiln. The tertiary air hose elbow comprises an outer wall and an inner wall, wherein the outer wall and the inner wall are arc-shaped, and at least one convex block is arranged on the inner wall. The invention has the advantages that: the convex block is arranged in the elbow and made of corundum-mullite pouring materials through pouring, so that the convex block bears washout and erosion of heated air flow; and due to the reduction of the washout and the erosion of the air flow to the inner wall of the elbow, the use performance of the pouring material on the inner wall of the elbow is ensured and the use performance of the elbow is improved.

Description

technical field [0001] The invention relates to an elbow of a tertiary air pipe of a cement kiln. Background technique [0002] At present, elbows are used in the tertiary air ducts of cement kilns to change the direction of the pipelines. The inner wall of the elbows is a smooth surface. The temperature of the tertiary air ducts of cement kilns varies greatly, the wind speed in the pipes is high, and the hot air flow contains a large amount of fine clinker. Particles, the tertiary air duct is directly scoured and eroded by the dust-laden hot air for a long time, which will easily cause the wear-resistant castable to fall off, reduce the service life of the elbow, and reduce production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is that the wear-resistant castable of the elbow is easy to fall off under the action of the elbow of the tertiary air duct, so that the service life is reduced. [0004] In order to s...
