A method for detecting the air leakage in the cylinder during the processing of the tobacco thread cylinder

Abstract

The invention discloses a method for detecting the air leakage rate of the interior of a roller in the roller processing course for tobaccos to be produced into shreds. The method is characterized in that a CO2 quantitative injection system is arranged on a hot-air pipeline outside the roller, and a gas sampling pre-treatment system is arranged at the inlet end of the interior of the roller and is connected to a CO2 on-line detection system; when roller equipment operates in a non-load state or in a material-carried state, CO2 gases are injected continuously according to a certain mass flow rate in the hot-air pipeline, and the CO2 volume concentration is detected in a real-time online mode through air exhaust sampling and purification filtering; the air leakage rate of the roller equipment in the processing state can be determined through calculation according to the flow and temperature of hot air inside the hot-air pipeline of the roller equipment, the CO2 gas injection flow and the detected CO2 volume concentration stable value. The method has the advantages that the air leakage rate in the roller processing course can be acquired through real-time online detection, the air leakage rate under different roller processing work conditions can be continuously monitored and analyzed conveniently, and therefore guidance and reference are provided for improving the processing quality stability of shred-producing tobacco rollers.

Description

technical field [0001] The invention relates to a tobacco processing technology, in particular to a method for on-line detection of air leakage in the processing process of drum-type equipment in a tobacco thread. Background technique [0002] In the tobacco industry, shredded tobacco processing is the process of loosening and re-moisturizing sheet tobacco raw materials after threshing, re-roasting and aging, adding moisture to leaves, shredding, drying, blending and flavoring, etc. into finished shredded tobacco for cigarette rolling. , this process is a necessary and key link in the processing of tobacco leaf raw materials in the cigarette processing process, and has a decisive impact on the quality and stability of cigarette products. [0003] The drum is the main form of main equipment used in the tobacco shred processing. At present, the key processes such as loosening and regaining moisture, shred drying, feeding and flavoring in the shred process all use drum processi...

AI Technical Summary

Problems solved by technology

For the drum process that has a great impact on product quality, due to the complexity of the processing equipment, the high-temperature and high-humidity characteristics of the airflow, and the openness of the working system, it is difficult to accurately measure the air leakage of the system simply by measuring the pressure difference and flow rate.

At present, there are no relevant patents and public literature reports on the detection method of air leakage in the process of tobacco thread drum processing
