Inner barrel of cement preheater

Abstract

The invention discloses an inner barrel of a cement preheater. The inner barrel comprises a barrel body, wherein the inner wall of the barrel body is provided with a buffer layer; the inner wall of the buffer layer is provided with arc-shaped ceramic hanging pieces and a connecting block which is used for connecting the ceramic hanging pieces; the top ends of the ceramic hanging pieces are provided with two buckles which extend upwards; each buckle comprises a horizontal base plate; the two sides of each base plate are provided with an upper side wall and a lower side wall which extend upwards in upper and lower reverse directions; each upper side wall is provided with a first screw hole; the lower ends of the ceramic hanging pieces are provided with two blocking holes for allowing the buckles to block; the connecting block, corresponding to the two first screw holes, is provided with two second screw holes; when the two ceramic hanging pieces are assembled, the buckles are blocked into the blocking holes; gaps between the buckles and the front side walls of the ceramic hanging pieces can be matched for accommodating the connecting block; and the first screw holes and the second holes are aligned. According to the inner barrel of the cement preheater, seamless connection between the ceramic hanging pieces is achieved, tightness is strong, the barrel body is protected from corrosion in a facilitated mode, and the service life of the barrel body is prolonged.

Description

technical field [0001] The invention relates to the technical field of preheaters, in particular to an inner cylinder of a cement preheater. Background technique [0002] At present, the cement preheater is a kind of equipment that uses the high-temperature exhaust gas of the rotary kiln to heat the cement raw materials. Most of the inner cylinders of the existing cement preheaters are connected by ceramic hanging pieces, but the existing ceramic hanging pieces The sealing of the connection gap is not good, which will cause damage to the cylinder and reduce the service life, and the high-temperature exhaust gas of the rotary kiln contains a large amount of dust, and the flow rate is fast. Cause damage to the ceramic hanging piece. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an inner cylinder of a cement preheater with a simple structure, easy processing, convenient installation and disa...
