Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] Such as figure 1 As shown, the array type droplet crystal preparation device of the present invention includes an operation box 1 and a solvent absorption device 4. The solvent absorption device includes a cylinder 42 and an air suction pump 41 connected to the cylinder. The cylinder is filled with solid absorption agent (such as: activated carbon), the cylinder body communicates with the cavity in the operation box through pipelines, and when the suction pump 41 works, the air in the operation box is sucked into the cylinder body for adsorption treatment.

[0038] The array droplet crystal preparation device also includes an array droplet preparation module 2 and a crystal growth substrate module 3 .

[0039] Such as Figure 4 As shown, the array droplet preparation module 2 includes a number of droplet tubes with the same structure arranged in an array, and ...

Abstract

The invention discloses a method and a device for preparing an array crystal. The array type crystal preparation device comprises an operation box, an array liquid drop preparation module and a crystal growth substrate module; according to the method, the crystal quality is accurately obtained by adjusting the volume of the array droplets, so that the target crystal form or crystal habit is obtained by accurately regulating and controlling the temperature and humidity. The method is quick and simple in operation, is economic and low-cost in process and is green and environment-friendly. The device can be widely applied to growth and preparation of various crystals (nanometer, atoms and molecules), especially a production process of medicine preparation.

Description

technical field [0001] The invention relates to an efficient and economical growth preparation method of various crystals and related devices. Background technique [0002] At present, crystal preparation methods mainly include melt growth method (pulling method, crucible drop method, zone melting method, flame melting method), solution growth method (aqueous solution method, hydrothermal method, flux method), vapor deposition method, solid phase reaction, etc. Among them, the solution growth method takes the hydrothermal method as an example. This method has extremely high requirements on equipment, requires high-quality crystal seeds, and its growth rate is slow and the period is long; the vapor deposition method can form a wide range of crystal types, and it is difficult to control product quality, operation and work. The device is complicated; the reaction speed of the solid phase reaction method is slow, and usually requires to carry out under high temperature (reactio...
