Sintering machine lubricating method based on multi-position monitoring air leakage points

Abstract

The invention discloses a method for online monitoring of air leakage points of a sintering machine and targeted lubrication, and belongs to the technical field of sintering machines. A thermometer and an air pressure sensor are installed at the position, close to a trolley, of each air bellow, data such as the temperature inside and outside each air bellow and the pressure difference inside and outside each air bellow are collected in real time, data interaction with a server is conducted in a wired or wireless mode, an expert system is established through an air leakage level neural network training model. and an online and offline system of air leakage grade parameter configuration is formed. Based on a single-line lubricating system, single-point quantitative filling is achieved by controlling a single-point electromagnetic valve, and the intelligent filling frequency of lubricating grease is achieved according to the air leakage grade of each air leakage point. The problems that in the prior art, air leakage points of a sintering machine cannot be monitored in real time, and lubricating grease cannot be intelligently injected are solved.

Description

technical field [0001] The invention relates to the technical field of sintering, and more specifically relates to a method for lubricating a sintering machine based on multi-position monitoring of air leakage points. Background technique [0002] Iron ore sintering is an important link in the modern metallurgical process, and the air leakage of the sintering machine seriously affects the economic and technical indicators of the sintering production process, increases the production cost, and reduces the sintering output and quality. There are many reasons for the air leakage of the sintering machine, but the air leakage between the trolley and the bellows is the main one. The traditional method of increasing the sealing performance is to lubricate the cylindrical tank and add lubricating oil through the oil pipe, but it cannot intelligently monitor the air leakage intensity of each air leakage point, nor can it change the frequency of refueling according to the air leakage ...

AI Technical Summary

Problems solved by technology

The traditional method of increasing the sealing performance is to lubricate the cylindrical tank and add lubricating oil through the oil pipe, but it cannot intelligently monitor the air leakage intensity of each air leakage point, nor can it change the frequency of refueling according to the air leakage situation for effective sealing. The sealing effect is not good and the air leakage rate did not decrease significantly
