Method for assembling rotary kiln

Abstract

The invention relates to a method for assembling a rotary kiln. The method for assembling the rotary kiln includes steps: respectively marking out end face center points on two end faces of each section of a barrel of the rotary kiln pertinently; erecting a laser emitting device which emits laser beams according to the technique inclination of the rotary kiln; adjusting relative positions of the laser emitting device and a preset section so as to enable the laser beams to shoot the center points of the two end faces of the preset section provided with a transmission gear to establish a laser datum line; sequentially adjusting positions of the other sections except the preset section according to the distances from the other sections to the laser emitting device from near to far so that distances from the shooting position of the laser datum line on each end face to the center point of the end face in an X-direction and a Y-direction are within a preset error range; and fixedly connecting the sections. By the aid of the technical scheme of the method for assembling the rotary kiln, the rotary kiln can be conveniently and rapidly assembled, measuring accuracy can be improved, deviation is avoided to the greatest extent, and design requirements of the rotary kiln are met.

Description

technical field [0001] The invention relates to a rotary kiln, in particular to a rotary kiln installation method for adjusting the alignment of the center line of the rotary kiln cylinder based on laser. Background technique [0002] Rotary kiln is the key equipment in the production process of alumina, cement and other industries. [0003] During the production and operation of the rotary kiln, the maximum flame temperature can reach above 1600°C, and the materials are burned into clinker through a series of physical and chemical changes such as drying, preheating, decomposition, and sintering in the rotary kiln. [0004] Since the rotary kiln is a device that operates continuously at high temperature for a long time, this working characteristic of the rotary kiln puts forward very strict requirements for its installation, and the installation quality of the rotary kiln will directly affect its working life. [0005] The rotary kiln is welded by multiple sections. The ove...
