Portable checking and information optimizing decisioning systme for rotary furnace maintenance

Abstract

A portable testing device integrated with testing, analysis, management and adjusting functions for rotary kiln maintenance comprises sensor, integrated signal collection device and portable computer. The device is flexible to rotary kiln leveled 2 to 9. The device is characterized by self-power supply, friend operation interface, easy use, multi function module, stable working, reliable and fit to the high temperature and dust environment. By using this device, an axial test takes less than two man-hours, accuracy for vertical and horizon axial test is within minus or plus 1.5mm.

Description

Technical field [0001] The invention relates to a rotary kiln health maintenance system, in particular to a portable detection and information optimization decision-making system for the rotary kiln health maintenance. Background technique [0002] Rotary kiln is the core equipment in the production process of cement, metallurgy, chemical industry and other industries. It usually weighs 1,000 tons and is more than 100 meters long. The number of supporting groups is 2-9. It is a heavy-duty, ultra-long, multi-fulcrum, and statically unstable Run the system. During the operation of the rotary kiln, due to the uneven wear of the supporting components, the change of the ambient temperature, the unbalanced subsidence of the foundation, the manufacturing and installation errors, etc., the operation axis of the rotary kiln shifts. According to many years of experience, when the axis deviation of the rotary kiln shell reaches ±10mm, the supporting bending moment and shell stress increase ...

AI Technical Summary

Problems solved by technology

The above-mentioned various detection methods have the following deficiencies to varying degrees: ①The measuring device is complex and expensive, and the measurement operation is cumbersome and error-prone, requiring professional operators; The error is large, which is not convenient for rapid detection; ③The position of the center of rotation needs to be estimated through the gap between the rolling ring and the cylinder, and the measurement method and system have large errors; ④When there are not many measuring points, the error caused by the out-of-roundness of the rolling ring and the cylinder cannot be eliminated; ⑤ The measurement accuracy is not high, the horizontal direction is ±1.5mm, and the vertical direction is ±2.5mm

However, due to the extremely uneven distribution of these loads, even if the axis deviation is adjusted to 0, the distribution of the supporting load of each gear is not balanced; secondly, due to the difference in structural strength, different load bearing and other factors, the fatigue damage and remaining life of the equipment components have been affected. Inconsistent, the axis deviation is adjusted to 0, even if the supporting load can be evenly distributed, it is unreasonable; moreover, the rotary kiln is a large-scale important equipment, and it should not be adjusted too much at one time according to the regulations, and the axis cannot be completely adjusted to a straight line

Therefore, using the traditional adjustment method of determining the axis deviation with the center is very blind, and it cannot adjust the equipment to achieve the longest service life under the optimal operation of each key component
