Device and method for measuring operating axis of barrel of rotary kiln

Abstract

The invention relates to a device and a method for measuring the operating axis of a barrel of a rotary kiln. The device comprises an installation bracket, a sliding rod, a pointer, a sliding block, a connecting rod, an outer fixed barrel, an inner telescopic barrel, a graduated scale, a connecting shaft, a rotary graduated disk, a fixed graduated disk and a water level. The measuring method comprises the following steps of: arranging the measuring device on sections on two sides of all wheel belts of the rotary kiln in turn, adjusting a position of the sliding block relative to the sliding rod, a position of the inner telescopic barrel relative to the outer fixed barrel and an angle of the rotary graduated disk relative to the fixed graduated disk, and measuring a spatial position parameter of a sensor at the front end of the inner telescopic barrel and measured data of the sensor at each moment in the process of operating the rotary kiln by one circle; and calculating and drawing the instantaneous operating axis of the barrel at each moment and the average operating axis of the barrel in the process of operating the rotary kiln by one circle by using the parameters and the measured data. By the measuring method, the condition that each bearing deviates from a theoretical bearing in the process of operating the rotary kiln can be more comprehensively measured.

Description

technical field [0001] The invention relates to a measuring device and a measuring method, in particular to a measuring device and a measuring method for the running axis of a rotary kiln cylinder. Background technique [0002] Rotary kiln is a rotary cylindrical calcining equipment for heat treatment of bulk or slurry materials, and is the core equipment in building materials, chemical industry, metallurgy and other industries. Whether the axis running state of the rotary kiln is normal or not directly affects the operating efficiency and product quality of the entire production line, so it is particularly important to detect its running state. [0003] Since the 1980s, people began to study the axis detection technology of the rotary kiln. At present, mature rotary kiln dynamic measurement systems and methods include: abroad, (1) the tire position measurement system pioneered in Poland; (2) the laser tire method developed by Danish FLS company; (3) the cylinder researched...

AI Technical Summary

Problems solved by technology

[0005] The indirect measurement method first assumes that the tire is a standard circle, and at the same time the measuring wheel and the tire do not slip relative to each other, and the method of measuring the circumference is used to obtain the diameter of the tire, so there will be a large error

(6) The zero-displacement direction key phase measurement method makes the sensor arrangement convenient, but uses an assumption that the cylinder section is in the process of rotation, and its center of rotation is unchanged. In fact, this assumption is unreasonable

At the same time, the direct measurement system uses high-tech instruments, the system is expensive and the operation is complicated, which is not conducive to the purchase and use of general enterprises
