Intelligent fault diagnosis system and method for large composite dry separator

Abstract

The invention discloses an intelligent fault diagnosis system and method for a large composite dry separator, and relates to the field of ore dressing machineries. The system comprises a detection module and an analysis and diagnosis module, wherein the detection module is used for detecting the temperatures of a bearing and a motor of the composite dry separator, the amplitude and frequency of the motor, the deformation of a beam and the noise decibel of the separator, and transmitting detection data to the analysis and diagnosis module; and the analysis and diagnosis module is used for analyzing the detection data, judging whether the composite dry separator has a mechanical fault or not, storing a fault waveform, predicting and judging a fault type, issuing a fault suggestion solution and sending alarm information. According to the intelligent fault diagnosis system and method for the composite dry separator, the safe operation of equipment can be guaranteed, accidents are preventedand reduced, the production efficiency is improved, and the economic loss of a coal preparation plant is reduced.

Description

technical field [0001] The invention relates to the field of mineral processing machinery, and more specifically, to an intelligent fault diagnosis system and method for a large-scale compound dry-process separator. Background technique [0002] my country is rich in coal resources, but due to the characteristics of "rich coal and little water" in the western region, as well as the huge consumption and output of coal, it has brought severe challenges to the living environment and ecological security of the people. It is necessary to improve the quality of coal products and the efficiency of coal before combustion. Pretreatment and quality improvement. Coal preparation is the basis for clean utilization of coal. The application and promotion of efficient dry coal preparation technology plays an important role in the deep processing of coal resources. Therefore, it is necessary to promote water-saving and environmentally friendly coal dry separation devices. The compound dry s...

Problems solved by technology

The compound dry separator does not require water and has a simple process. It can be used for separating lignite and other easily muddy coal, high-sulfur coal desulfurization and coking coal pre-discharging. However, due to its large size and vibration equipment, the mechanical structure Structural fatigue is prone to occur, causing beams and other main components to break. If the failure is not detected and eliminated in time, it is easy to cause large-scale damage to the whole machine under the action of vibration. At the same time, the vibration excitation device is a high-speed rotating part. If the fault is not eliminated in time, it is easy to cause damage to a larger area and bring losses to production.
