Optimized Design Of Clarification Chamber Hole Baffle Structure

In the rare earth extraction process,the mixed clarification chamber is widely used due to its simple structure,low installation environment requirements,and superior extraction performance over other conventional extraction equipment.At present,domestic and foreign scholars have studied the internal flow field of the extraction tank clarification chamber for several decades.It is concluded that advanced theory has profound theoretical guidance for studying the path of extending the clarification chamber and the internal clarification chamber structure to improve the clarification effect.significance.However,with the development of industry,these designs can not meet the industrial production needs,and because of the large area of equipment and the limitations of separation,the efficiency of rare earth purification has been affected.To this end,this paper proposes to add holes to the baffle to observe the thickness of the dispersion belt to show an optimized design for the clarification efficiency.In this paper,a 200 L extraction tank clarification chamber of a research institute is used as a research model.It is proposed to add a hole-like structure design to the clarification chamber baffle,and design the clarification chamber model by means of the Designermodler's three-dimensional mapping module in ANSYS software,and then pass the CFX 19.1 software.The water and P507 were used as the clarification process analysis of the aqueous phase and the organic phase medium respectively.The thickness and clarification time of the dispersion zone were optimized,and the optimal pore baffle was designed to provide a reference for the development of the clarification chamber structure.Through the simulation comparison between the ordinary baffle and the holeshaped baffle in the clarification chamber,it is found that the thickness of the baffle dispersion belt with the pore structure is thinner than that of the ordinary baffle dispersion belt,and can effectively promote the mixing of the dead zone in the clarification chamber.The liquid enters the clarification chamber for reaction.On the basis of this,the parameter simulation of the circular hole baffle and the rectangular hollow baffle is studied,and the optimal position and layout of the circular top baffle and the rectangular hollow baffle in the clarification process are analyzed.The effect of thickness.In the hole-containing structure baffle,a six-blade turbine and a 45° four-angle impeller are respectively added to study the horizontal position of the paddle and the stirring speed.According to the analysis,when the distance from the baffle is too close or too far,the thickness distribution of the dispersing belt is confusing,so it is necessary to ensure that the stirring paddle is at a certain position from the baffle.In addition,the stirring paddle speed was simulated and the clarification effect at the optimum speed was obtained.
