Method and system for monitoring rotary kiln running state and adjusting method of kiln

Abstract

The invention relates to a detection method for the operation state of rotary furnaces, a system thereof and a furnace adjusting method. The detection method comprises: correlating the rotation direction of a rotary furnace and the detected working current curve of a furnace drive motor, the rotation direction of the rotary furnace, and detected the mechanical parameter curves about force on each support wheel and furnace transmission small gear base, to realize online detection for the abnormal change of the operation state of the rotary furnace; according the average value of the working current of the furnace drive motor in each rotary period of the furnace, the difference between the maximum and minimum values of the working current, the decrease of the mechanical parameters about force of each support wheel and furnace transmission small gear base, referring to the measurement results of the rotation central line of the rotary furnace and the geometric position of each support wheel, to confirm the adjustment direction and data of each support wheel, according to the average value of the working current of the furnace drive motor, the decreases of the difference between the maximum and the minimum values, and the decreases of the mechanical parameters about the force on the support wheels, judging the correctness of the direction adjustment of each support wheel, deciding the accurate adjustment value of each support wheel. The device is simple, and has simple operation, reliability, long service life, high performance price ratio and wide application.

Description

technical field [0001] The invention relates to a measurement method and a measurement system for the operating state of a rotary kiln and an adjustment method for the kiln, in particular to a monitoring method and system for the relationship between the drive motor current of the rotary kiln and the rotation orientation of the kiln and an adjustment method for the kiln. Background technique [0002] Rotary kiln is an important firing equipment for cement, non-ferrous and ferrous metallurgy, chemical industry and other industries. The rotary kiln is mainly composed of a cylinder, a transmission gear device, three or more sets of tire belts and support rollers. The working characteristic of the kiln is that it must operate continuously on multiple supporting points without interruption for a long time. Kiln alignment is the key to ensure the long-term operation of the kiln. During long-term production, a series of mechanical obstacles will be caused due to the uneven subsiden...

AI Technical Summary

Problems solved by technology

These patented methods require professionals to operate special measuring instruments on the kiln site. Due to the complex operation process on site, the operators are required to have rich professional experience and high technical level. The on-site inspection generally takes at least 2 working days to complete. , so the popularization and application of its technology requires professional training

Due to the influence of high temperature, strong vibration and dusty environment on the kiln site, it is easy to greatly interfere with the measurement accuracy of operators and instruments

Due to the complex mechanical movement of the kiln site, the adjustment of the supporting wheel is only based on the measurement results of the center line and deviation of the kiln operation and the radial deflection of the kiln ring gear. The results are not always obvious and effective, and there are no other technical parameters at present. Able to feedback and verify that the kiln adjustment method is correct and effective
