Problems solved by technology

[0007] However, the current method scans the temperature field outside the kiln body to analyze whether there is a kiln ring. The detection speed of this method is slow. Field changes take a long time (hours or even longer), so detection lags and efficiency is low

Abstract

The present application relates to a rotary kiln fault detection method, device, computer equipment and storage medium. The method includes: constructing a finite element model of the internal working area of ​​the rotary kiln according to the physical field parameters of the rotary kiln, and calculating the characteristic frequency of the internal pressure field of the rotary kiln according to the finite element model; obtaining multiple different The measurement frequency of the position is calculated according to the measurement frequency and the characteristic frequency of the internal pressure field of the rotary kiln to obtain the downstream position characteristic frequency; according to the downstream position characteristic frequency, a dimensionless time-domain index kurtosis analysis is performed to obtain the downstream position The kurtosis value of the dimensionless time domain index of the position; when the kurtosis value of the dimensionless time domain index is greater than or equal to the preset value, it is judged that there is a fault in the rotary kiln. The method can improve the efficiency of rotary kiln fault detection.

Description

technical field [0001] The present application relates to the technical field of rotary kiln fault models, in particular to a rotary kiln fault detection method, device, computer equipment and storage medium. Background technique [0002] Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to different materials. The raw meal powder is fed into the kiln shell from the high end of the kiln tail shell, and the material tube is fed into the kiln shell. Due to the inclination and slow rotation of the kiln shell, the material will roll along the circumferential direction and flow from high temperature to the axial direction. The compound movement of low-end movement, the raw material is decomposed and fired in the kiln, and the clinker is discharged from the bottom of the kiln shell after burn...
