The Development Of Laser Measuring System Of The Rotary Kiln's Exterior Outline Based On LabVIEW

Rotary kiln is the main equipment of the some kind's material to. Its apply in ferrous metallurgy, colored metallurgy, chemical industry, building materials (cement), professions and so on nonmetalliferous ore, fire-proof material, papermaking .etc. As the Crucial equipment, it has vital significance that the kiln keeping a good work. In the long-term production process of kiln, sometimes the lining brick of kiln body falls off and induces "the red kiln" accident, the kiln tube has produced the permanent radial direction distortion. The coherence of the lining brick which are built after the distortion is bad. It's easy to fall off once more and induce "the red kiln" the accident again, therefore the rotary kiln use factory earnestly hope that they can measure the tube body and the turn belt contour beats in carries, in order to take the corresponding repair measure and enhance the running rate of the rotary kiln and the overhaul quality specification.This article studies and analyzes the reason of the kiln body as well as the survey method of rotary kiln tube body distortion in the domestic and foreign country. Contrasting to the process analysis, it proposes the measuring technique of the new tube body distorted as well as the recent data processing method, and make the detailed elaboration.It proposes design proposal of measurement system which based on the laser position transmitter JGJ through the study of each kind of rotary kiln tube body. JGJ is one kind of measurement sensor applying in the high performance comprehensive distance in the industry, it can carry on the non-contact precision measuring to the great distance. We can get the datas of some sections by measuring the body of the Rotary kiln.Then ,we can gain the 3D drawing by collecting all the sections. This system includes structural design, software design as well as the programming design based on LabVIEW man-machine contact surface.We deeply research and analyse the virtual instrument technology, did a lot of work in data collection. And designed each module of the application based on LabVIEW platform, generally including communication of the SCM and the computer based on LabVIEW, data processing, data input and output etc. We design the artistic and friendly man-machine interactive contact surface, enable the user directly and quickly get the result.The instrument has got the grant of Chinese utility model patent whose number is 200720084382.6 .It has performed well in Huaxin Cement company. Optical, mechanical, electronic and computer software technology have been apllied in the instrument, which has made up for the domestic shortage in the area.
