Improved Design Of Vane Wheel Equipment And Discrete Element Simulation

Foundry industry is the basic manufacturing industries, all industries are inseparable from the castings. China is already the world's casting production power. Foundry industry is more energy and resource consuming and polluting industries. According to statistics, China produced the foundry industry of the old year a total of about 3,000 tons of sand. If do not recycling the old sand out but the emissions of our country's limited resources, a great waste of sand, followed by serious environmental damage. Sand reclamation technology can re-use the old sand, not only reduces the environmental pollution, and saves the use of new sand, and ultimately bring economic benefits for the enterprise.The subject from the National Natural Science Foundation project, the project name:"Casting clay (mixed) for the old sand resin sand core regeneration mechanism and process of research", the project approval number:50665004.At present, domestic and foreign have been dealing with some of the old sand regeneration methods and equipment, but in recent years the application of some new organic binder on the Sand reclamation equipment requirements are higher, it is necessary to study some new methods and equipment.Vane of the grinding wheel with the old sand regeneration machine is a new type of recycling equipment, It is the use of group wheel and leaves the relative speed difference, wheel by wheel and the extrusion gap on the sand, friction, collisions as the main mechanism of a dry recycling equipment. In this paper, the original vane wheel reclaimer, and found that regeneration of high clay content of sand, regeneration is not ideal, it is essential to the original vane wheel reclaimer for further analysis. Regeneration of the original vane wheel machine number of improvements designed mainly to solve the difficult installation of the blade, wheel both sides of the leakage of sand, leaves group can not rotate and so on. By adjusting the processing time, wheel speed, blade and wheel distance, the number of leaves of the four parameters of the improved prototype, experiment.Through the analysis of experimental results obtained by the vane wheel reclaimer regeneration one of the best set of parameters. The original prototype by comparing the results found that the improved vane wheel reclaimer regeneration than the original blade wheel drive regeneration has increased significantly, this vane wheel reclaimer more successful improvement.In this paper, discrete element software PFC3D institutions of vane wheel built a simplified model of regeneration, and regeneration of sand in the wheels inside the blade simple movement analysis, the sand in the regeneration of vane wheel inside the movement and the energy Changes.
