| Rotary kiln is widely used in product ional department of cement, metallurgy, fire-resisting material, chemical engineering and so on. In production, rotary kiln's inner liner, kiln supporter's lifetime have very light relationship with the running stale of its axis. It was found by research that rotary kiln's axis whether or not in a line was the key factor of keeping rotary kiln regular service for long run.By analyzing and comparing the monitoring technique of rotary kiln's axis at present at home and oversea, this paper puts forward a brand-new monitoring method of more advance and more scientific, that is the keyway-phase measure in direction of null displacement of the center of gyration measuring. In this way, rotary kiln's feature of its bearing pressure and struclurc are thought at all points. In this new method, it's without fixing difficulty, operating complication and great measuring error of former measuring syslem, which measure axes with the way of Ihe keyway-phase measure in direclion of no shell strain under rotary kiln shell. This method is the first used at home at present, and it is valuable in practice.We developed the monitoring syslem software by adopling Delphi language which has a mighty function, and is object-oriented. Based on the feature and requirement of the system, using multithreading to program, it realized much function of background's of the computer such as real-time sampling, wave analyzing, and data processing; and it also realized much function of foreground's of computer such as dynamic figure displaying, data-base querying, printing, giving an alarm. And at the same time, combined Delphi language, which has agility and strong ability oi'managing database, with Mallab which has superexcellenl ability of scientific compulalion, developing guiding program of optimi/.c adjusting kiln which based on Delphi database and Matlab scientific computation. It provides theoretical reference of more scientific for adjusting kiln. |
