Problems solved by technology
[0003] At present, there is no online dynamic telemetry method for the super-large rotary kiln shell, only the original method of static detection after shutdown and cooling, which affects production and causes huge losses, which is not conducive to the energy saving, production increase, consumption reduction, and environmental protection required in social development. National policy, simultaneous firing and baking rotary kiln, the highest temperature in the kiln is above 1500°C, the phenomenon of thermal expansion and contraction is extremely obvious, and the cold state detection data is very different from the hot state. In 1995 For the suspended rotary kiln designed in the future, the center line of the kiln cylinder is in a curved state in the cold state, and in a straight line state in the hot state. The online detection of the hot state can truly reflect the actual operating state of the rotary kiln and provide the most accurate rotation adjustment. Theoretical basis

The invention provides an ultra-large type rotary kiln on-line dynamic remote measurement method. Through arrangement of total stations and prisms, a scientific and reliable measuring system and a measuring basis are established, so that measurement precision is higher and cost is low; with influence of foundation vibration of a rotary kiln on measurement precision being taken into overall consideration, the method is closer to practical production; remote measurement is adopted to prevent superposition, which leads to inaccurate measurement result, of detection errors caused by strong vibration of the running rotary kiln due to close-range measurement; and in the operation process of the rotary kiln, temperature of the cylinder surface reaches 200-400 DEG C, which far exceeds the use ambient temperature of precision test equipment, and through the remote measurement method, detection precision is improved and production is not influenced, and meanwhile, normal use of precision test equipment total stations can be ensured.
Description
technical field [0001] The invention relates to a remote detection technology, in particular to an online dynamic telemetry method for a super-large rotary kiln. Background technique [0002] The weight of super large rotary kiln can reach 2500 tons-16000 tons, and the length can reach 20 meters-130 meters. Large-scale rotary kiln has high output and good economic benefits, but the deformation of the rotary kiln will cause amazing losses, such as large vibration caused by plastic deformation. The elastic deformation will drop the refractory bricks so that they will burn through the kiln body, and the permanent deformation will lead to direct scrapping. Therefore, during the operation of the ultra-large rotary kiln, it is necessary to be able to detect the operating status of the rotary kiln. [0003] At present, there is no online dynamic telemetry method for the super-large rotary kiln shell, only the original method of static detection after shutdown and cooling, which af...
