Optimization Analysis On Design Parametric Of The Equipment With High-Speed Rotary Stream For Green Sand Reclamation

In recent years, Chinese annually casting output is above 30 million tons. Green sand reclamation can reduce environmental pollution and resources waste, and realize green production. Green sand reclamation have epigranular, smooth surface, good refractoriness and so on. That will improve foundry sand and casting quality.At present, green sand equipment exist low regeneration rate, high broken rate, high energy consumption, complex regeneration technology, persistent and so on. So a new method is needed to look for in order to improve green sand reclamation competent and meet the requirements of green sand reclamation. Rotary stream equipment for green sand reclamation base hot method and current reclamation mechanism. The new green sand reclamation equipment apply for rotary stream for power source.In this paper, by comparing advantage and disadvantage of different method of green sand reclamation, dry process is an economic and effective method. Air current regeneration have the advantages of steady, reliable and maintain. So it become the main method. By researching the theory of rotary stream jet, rotary stream jet air with strong rotation have strong entrainment ability and blending effect. The rotary stream jet air with strong rotation make green sand mutual scrub. That is in favor of reclamation effect. Transversal blow reclamation equipment exist the phenomenon of particles easily broken and low productivity. And it is found out that hitting power decrease with decrescence of deflection angle. So the new method of rotary stream green and hot process is proposed.In this paper, rotary stream equipment base current green sand reclamation mechanism and low temperatures heating method for clay combination green sand. After minutely analyzing rotary stream happened method, guide blade rotation method apply to the stream happened equipment in the equipment. And through plenty of simulation result of Fluent, guide blade leaf with rounded airfoil can produce strong rotary stream jet. On the same mounting axel, proper radian, installation angle, the number of leaves, length of chord, and height of leaf all can make strong rotary stream jet, especially radian, installation angle, and the number of leaves can make strong effect for rotation. By the result of simulation, the funnel of green sand should be fix up near the inlet of rotary stream happened equipment. That is in favor of green sand friction effect and raising green sand velocity. And By designing inlet of green sand funnel and intake of air, the quantity of green sand can be adjusted, and homogeneous quantity of air can be obtained. And By using dispersed phase model in Fluent, floating track and flow velocity of green sand is analyzed. Finally, processing step and advantage of the equipment with rotary stream in high speed is analyzed.
