Abstract
The invention relates to a crystal carrying frame used for KDP type crystal growth. The crystal carrying frame used for the KDP type crystal growth comprises a crystal carrying plate, two side bars, an upper cross bar, two stirring paddles and a rotating shaft, wherein joints between the upper ends of the two side bars and the upper cross bar are smoothly connected by virtue of a rounded corner, one trapezoid stirring paddle is arranged at each of symmetrical positions of the two sides of the rotating shaft of the upper cross bar, edges of each stirring paddle are rounded corners respectively, and the stirring paddle is fixed on the upper cross bar by virtue of a stirring paddle connecting rod. Simulation analysis and flow field visualization experiments show that the crystal carrying frame used for the KDP type crystal growth has the advantages that perturbation on a solution is reduced in minimum limit, and solution stability is guaranteed; and multiple large-scale eddy flows are formed in the whole growth groove, and crystal surface and a region in the whole growth groove can be communicated, so that solute macroscopic distribution is more uniform, and especially solute transportation and solute supply nearby a crystal growth boundary layer can be benefited. Crystal growth experiments show that the crystal carrying frame used for the KDP type crystal growth can obviously reduce probability that defects such as occlusions are produced, growth rate of crystals is improved, and more uniform and higher-quality crystals are grown.
Description
Technical field
The present invention relates to KDP crystalloid, be specifically related to a kind of carrier crystal stand for the growth of KDP crystalloid.
Background technology
At present, the ICF device of various countries all needs a large amount of high-quality, bigbore KDP crystalloid. Application number201410186495.1, the patent of invention of application publication number CN105088343A has been introduced a kind of KDP class crystalline substanceBulk-growth carrier crystal stand and growing method. A year brilliant plate for this carrier crystal stand is square, and in growth course, seed crystal frame revolvesWhile turning, carry the edges and corners rotational angular velocity that brilliant plate is square larger, larger to the local dip of growth solution, affect moltenLiquid stability, easily produces stray crystal, is unfavorable for the growth of crystal; This seed crystal frame rotates the macroscopic view of the solution bringingImmixture is very weak, and the solute Distribution of crystal growth is inhomogeneous, is unfavorable for the solute transport in crystal growing process.The patent of invention of application number CN201510762023.0, publication number CN105256377A has been introduced a kind of KDPThe carrier crystal stand of crystalloid growth. When rotating in order to reduce carrier crystal stand, this invention to the violent disturbance in the part of solution, incites somebody to actionCross tube changes upper horizontal stripe that corner angle are smooth into, two side levers is changed into two circular lateral columns, will carry brilliant plate and change circle intoPlate, but upper horizontal stripe is comparatively lofty with the junction geometry of two lateral columns, to solution when carrier crystal stand rotatesLocal violent disturbance is still larger; In order to improve macroscopical mobility of solution, these innovation and creation at upper horizontal stripeOn two leg-of-mutton paddles have been installed, with respect to application number 201410186495.1, application publication numberThe patent of invention of CN105088343A has improved the mobility of solution significantly, but leg-of-mutton paddle instituteThe stirring action that can bring is limited, and the micromixing that this seed crystal frame rotates the solution bringing is complied with near acting on crystalSo very weak, solute Distribution is inhomogeneous near crystal growth boundary layer, easily produces and the defect such as contains, and be unfavorable for crystalline substanceBody Fast Growth.
Summary of the invention
For overcoming the KDP crystalloid the problems referred to above that existing carrier crystal stand exists of growing, the invention provides a kind of forThe carrier crystal stand of KDP crystalloid growth. This carrier crystal stand can grow the KDP of more even high-quality more rapidlyCrystalloid.
Technical solution of the present invention is as follows:
For a carrier crystal stand for KDP crystalloid growth, comprise and carry brilliant plate, two side levers, cross tubes and revolveRotating shaft, the two ends of described cross tube are connected with the described brilliant plate that carries through described side lever, and described rotating shaft is fixedIn the centre position of described cross tube, its feature is the described upper end of two side levers and being connected of cross tubePlace is by fillet smooth connection, the symmetric position on the rotating shaft both sides of described cross tube is each install one upper little underLarge prismatoid paddle, the seamed edge of this paddle is fillet, is fixed on by columniform paddle connecting rodOn described cross tube.
Technique effect of the present invention is as follows:
Show that through sunykatuib analysis and flow field experiment shows, the present invention is with the junction of two side lever upper ends and cross tubeBy fillet smooth connection, the seamed edge of prismatoid paddle becomes fillet, has minimally reduced micro-to solutionDisturb, ensured the stability of solution; Two up-small and down-big prismatoid paddles promote in the time rotating with carrier crystal standThe solution in paddle front upwards flows, and the solution that causes each paddle both sides flows downward, thereby wholeIn individual growth groove, form multiple large-scale eddy current, can UNICOM's plane of crystal and whole growth groove in region, make moltenMatter macroscopic view distributes more even, is particularly conducive near the solute transport of crystal growth boundary layer and solute and suppliesShould. Crystal growth experiment shows, the present invention can obviously reduce the probability that produces defects such as containing, accelerates crystalThe speed of growth, grow more even, higher-quality crystal.
