Novel structure of coal injection pipe head

Abstract

The invention provides a novel structure of a coal injection pipe head. The castable of the front head of a coal injection pipe is thickened, clasp nails are added, and a reinforcing rib structure is added in the inner pipe at the rear head, so that the strength and the wind erosion resistance of the coal injection pipe are increased, and the service quantity and the maintenance frequency are reduced. The use value is high, and the abrasion resistance and impact resistance effects are obvious.

Description

technical field [0001] The invention relates to a novel structure of a coal injection pipe head. Background technique [0002] The coal injection pipe head of the rotary kiln is exposed outside. After a long period of weathering and burning, the castable of the coal injection pipe head is often weathered and peeled off, resulting in a short service life and a large amount of maintenance. Contents of the invention [0003] In order to solve the above problems, the present invention provides a novel structure of a coal injection pipe head. [0004] The present invention is realized in the following way: the pouring material at the front of the coal injection pipe is thickened, and nails are added, and the inner pipe at the back is added with a reinforcing rib structure. [0005] The beneficial effects of the invention are: the strength and wind erosion resistance of the coal injection pipe are increased, the amount of maintenance and the frequency of maintenance are reduced...
