Problems solved by technology
[0003] In the recycling of waste liquid crystal screens, the recycled liquid crystals cannot be reused because they absorb moisture in the air, and the use of liquid crystals with high moisture concentration will cause abnormal display on the display screen
At present, the filtration method is generally used to remove the moisture in the recycled liquid crystal, but the recycled liquid crystal filtered by the filtration method is difficult to meet the use standard of the liquid crystal

The invention discloses a purification device for recovering liquid crystal. The purification device comprises a cooling barrel and a stirring barrel. The stirring barrel is arranged in the cooling barrel. A cooling liquid is filled in the cooling barrel. The temperature of the interior of the stirring barrel is -20 DEG C to 20 DEG C due to the cooling liquid. The stirring barrel comprises an upper cover, a stirring rod, and a barrel for storing liquid crystal. The upper cover covers on the upper end of the barrel. The lower end of the stirring rod is arranged in the barrel. The upper end of the stirring rod penetrates the upper cover. The lower end of the stirring rod is provided with a stirring blade. The upper cover is provided with an air inlet and a suction hole. The liquid crystal in the stirring barrel is maintained in a low temperature and low pressure state; then recovered liquid crystal in the barrel is fully stirred by the stirring blade of the stirring rod; an external negative pressure device can effectively and maximally extract water from recovered liquid crystal so that the recovered liquid crystal can reach the using standards of liquid crystal; the waste and old liquid crystal display (LCD) screens can be recovered, moreover, the components of liquid crystal are not changed, the characteristics of liquid crystal are not influenced, and the manufacturing cost is reduced.
Description
technical field [0001] The invention relates to the technical field of liquid crystal purification, in particular to a purification device for recovering liquid crystals. Background technique [0002] After some substances are in the molten state or dissolved by solvents, although they lose the rigidity of solid substances, they obtain the fluidity of liquids and retain the anisotropic orderly arrangement of some crystalline substances, forming a combination of crystals. It is an intermediate state with some properties of the liquid, and the alignment-ordered fluid that exists during the transition from solid to liquid becomes liquid crystal. [0003] In the recycling of waste liquid crystal screens, the recycled liquid crystals cannot be reused because they absorb moisture in the air, and the use of liquid crystals with high moisture concentration will cause abnormal display on the display screen. At present, the filtration method is generally used to remove the moisture i...
