MICROPROCESSOR-BASED CONTROL OF STATIONS OF PNEUMATIC CONVEYOR SYSTEMS AT THE ENTERPRISES OF MINING AND METALLURGICAL COMPLEX

Bestvater D.V., Khmara V.V., Kabyshev A.M., Lobotsky Y.G.

Automatic management of any technological process involves continuous or periodic monitoring of the parameters determining this process. For mining, mineral processing and metallurgical enterprises and factories such parameter is the material composition of the feedstock, fluxes, used reagents, intermediate products, finished products, tailings and sewages. Information about chemical composition of these products is obtained by selection and subsequent analysis of representative samples. The aim of this work is the development of a system of container delivery of process samples for express analysis, based on use of unified assemblies functioning under control of the universal microprocessor system. Solution of this problem allows to simplify the process of adapting the system to particular technological process, improve its reliability through the use of unified assemblies and simplify service operation. The scheme of container delivery system of samples, which includes load and unload stations of a transport container was developed. The stations are made on the basis of unified assemblies and elements. Such unified assemblies include: pneumatic cylinders, electro pneumatic valves, valves, distributors and magnetic sensors. These assemblies and elements are used for moving a transport container within the stations as well as through transport pipelines. Control of the assemblies of a station is performed by using a microprocessor control system. The article describes the optimization of control signals generated inside the stations and coming from the auxiliary system devices such as: samples loading station and samples unloading station. Control signals provide optimal algorithms of the functioning of the system. Algorithms of functioning of the stations were developed. Principle diagram of the microprocessor control system based on modern element base was also developed. The control system is flexible, allows not only to implement developed algorithms, but also can be easily adapted to perform more complex modes of operation of the stations, it allows you to extend the functionality of the system. Software for microprocessor control system of container delivery of samples was developed using a computer simulation.
