Research On The Operating State Inspection System For Rotary Kiln

Rotary kiln is the key equipment in the productions of corresponding enterprises of building materials, metallurgy, chemical industry, mineral processing and environmental protection and so on. Once shutdown of kiln will bring interruption to the whole production line, and make great productivity losses. Currently, when domestic rotary kilns appear faults, workmen still maintain these kilns by traditional afterward-maintenance method most of the time. For the large-scale rotary kiln, the method is inefficient and expensive, and it needs to stop the kiln during large-scale maintenance, so, the maintenance method will affect production of enterprise and can't favor the health movement of all equipments. By building rotary kiln real-time monitoring system, which monitors some important parameters, it can prevent some faults from emerging in time, and improve the running rate of rotary kiln and the quality of product.This paper first analyze and compare the status of domestic and international rotary inspection system, then established the measuring type of the parameters for the Rotary inspection system. Includes the center line of rotary kiln, wheel diameter, tire diameter, tire clearance, the ring gear deflection, tube deflection, described in detail the principle and method various of operating parameters.This paper based on C8051F040 MCU, SQL server and LabVIEW, running on the rotary inspection system overall design, and its main components, namely sensor layer, lower computer hardware and software and PC software designed in detail.For the sensor layer, compared to current sensor type, rotary kiln to be under the inspection of the parameter type, considering the hardware operating environment, select the appropriate sensor and the arrangement of its reasonable, At the same time to center line cylinder sensor measurement point example, the design of the sensor bracket, For the lower computer hardware, with C8051F040 MCU platform, carried out on the lower machine design and the function module, the main function modules include multi-channel data acquisition module, LCD module, communication module, an external memory module, JTAG interface module and power module, For the lower computer software, Design inspection instructions and storage format of the data collected, Overall lower computer software design and programming of all functions, Including C8051F040 initialization, LCD process, data collection procedures, serial communication program, USB communication procedures。Software for PC, First, Introduces the Lab VIEW software development environment, then, Elaborate way of Lab VIEW and the database link; Finally, the PC software for the design of each functional module, Including the system menu module, communication module, user management module, device management module, feature extraction module and display and alarm module, For the sensor layer, compared to current sensor type, rotary kiln to be under the inspection of the parameter type, considering the hardware operating environment, select the appropriate sensor and the arrangement of its reasonable,Rotary Kiln inspection system to the lower position by on a regular basis to detect operational parameters of rotary kiln, Improve the reliability of the next-bit machine, PC kiln at the same time be able to manage users, devices and test data, Lab VIEW graphical output, it makes the management of the rotary kiln systematic, Rotary kiln can assess the long-running, in order to better develop maintenance and repair program Conducive to long-term safety of rotary kiln and healthy run.
