New Methods Of Measuring The Axis And Cylinder Roundness Of Rotary Kiln

Rotary kiln, as building materials, metallurgy, chemical and other industrial production equipment, its operating status have an important impact on production which is directly related to the benefits. Rotary kiln axis of implicate the life of the internal firebrick, the force of the rollers and tires, drive pinion'mechanical wear; the roundness of the cylinder can be directly reflected in the internal firebrick bond situation, the accuracy of the axis of detection.The rotary kiln axis detection has two ways:indirect measurement and direct measurement. Indirect measurement of cylinder axis derived by measuring the tires and rollers at piers that is not the whole, and the accuracy of measurement is low accuracy and can only be measured on the piers, which is difficult to estimate the shell hanging in the air; direct measurement method is measuring the cylinder directly to find the cylinder axis, which is assumed that the shell is a perfect circle and calculate the center of the cylinder. In fact, the shell has welding scars and deformation. If not isolated the bending and deviation round error of the shell, the error of direct measurement method will be even greater. This paper presents dynamic three-point method error separation techniques, to isolate the rotary kiln rotation axis and cylinder roundness error to accurate detection of the cylinder bending to provide a more accurate measurement results for manufacturers.This article details the introduction of the roundness error of the outline of how the three-point method of roundness error separation techniques separation rotary kiln and rotary center of the error, and describes the use of Total Station make different measurement cross-section associated to measure the rotary kiln whole axis bending;and the outline of roundness error measurement methods. Detail descriptions of the selection and parameters of the testing equipment, laser sensors, and other hardware selection and parameter; the design of mechanical devices, including fine adjustment device, reflecting device, supporting device; software design, including control of the laser ranging sensor data collection, data preservation and data processing, the rotary kiln axis bending and cylinder roundness error separation, and measurement results are draw as three-dimensional renderings, so that the measurement results more intuitive. Finally, suggest the cylinder roundness error correction and related recommendations.The thesis designs dynamic rotary kiln axis and the roundness error of the measurement devices and measurement software, combined with the actual site design and method of measurements. The measurement method is simple; measurement equipment is precise, so that it can be promoted to the manufacturers that have broad market prospects.
