Problems solved by technology

[0002] The cyclone preheater for cement kiln is a raw material preheating device in the cement production line. At present, whether the inner cylinder is welded as a whole or suspended in pieces, most of the inner cylinders are made of heat-resistant and wear-resistant special alloy steel, which is expensive. The environment and the characteristics of the metal itself cause it to be easily corroded, have a short service life, and need to be replaced frequently, which increases the production cost

Abstract

The invention discloses a cyclone preheater inner barrel for a cement kiln. The cyclone preheater inner barrel comprises a metal barrel body, wherein a meshy metal wire layer is welded on the inner wall of the metal barrel body; arc-shaped ceramic hanging pieces are mounted on the inner wall of the metal wire layer; a T-shaped bump is arranged on the right side wall of each ceramic hanging piece; a T-shaped groove is formed in the left side wall of each ceramic hanging piece; the ceramic hanging pieces are connected in a manner that each groove is connected with the corresponding bump in a sleeving manner; wavy wind guide grooves are formed in the front side wall of each ceramic hanging piece; a mounting hole penetrating through the ceramic hanging piece is formed in each of the four corners of the front side of each ceramic hanging piece; and the surfaces of the ceramic hanging pieces are coated with a boron nitride coating layer. The invention aims to provide the cyclone preheater inner barrel for the cement kiln, which is abrasion resistant, high temperature resistant, corrosion resistant and long in service life.

Description

technical field [0001] The invention relates to cement production equipment, in particular to an inner cylinder of a cyclone preheater for a cement kiln. Background technique [0002] The cyclone preheater for cement kiln is a raw material preheating device in the cement production line. At present, whether the inner cylinder is welded as a whole or suspended in pieces, most of the inner cylinders are made of heat-resistant and wear-resistant special alloy steel, which is expensive. The environment and the characteristics of the metal itself cause it to be easily corroded, have a short service life, and need to be replaced frequently, which increases the production cost. Contents of the invention [0003] The object of the present invention is to solve the disadvantages of the above-mentioned technical problems, and provide a cyclone preheater inner cylinder for cement kiln with wear resistance, high temperature resistance, corrosion resistance and long service life.
