Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1-3, the utility model provides a kind of technical solution: a kind of liquid level it is controllable prepare liquid crystal display material
Cylinder 2, the gas have been bolted to connection with the left and right sides of extraction equipment, including tank body 1,1 top of tank body
The top of cylinder 2 has been bolted to connection support plate 3, and the bottom end of the support plate 3 has been bolted to connection push rod 15,
The push rod 15 extends downward into the inner cavity of tank body 1 through the top of tank body 1, and the bottom end of the push rod 15 is bolted company
It is connected to piston plate 9, the left and right ends of the tank body 1 are respectively equipped with integrally formed first charging aperture 5 and second charging aperture 6, institute
State and be respectively equipped with extraction outlet 11 and waste outlet 12 on the left of the bottom end of tank body 1, be equipped on the right side of the bottom end of the tank body 1 one at
The return pipe 7 and gas valve 10 of type, the return pipe 7 are right far from the top that one end of 1 bottom end of tank body is fixedly attached to tank body 1
Side wall, the return pipe 7 are in series with back flow container 8, and the first charging aperture 5, second charging aperture 6 extract outlet 11, waste outlet
12 and the both ends of return pipe 7 be in series with valve 14.
Wherein, the top of the tank body 1 is equipped with integrally formed venthole 4, and the bottom end of 1 inner cavity of tank body is fixedly connected
There is supersonic generator 13, described time flow container 8 is non-tight tank, and the piston plate 9 includes the platen that 9 inner cavity of piston plate is arranged in
92 and the rubber ring 91 that is set at 92 outer rim of platen, the diameter of the rubber ring 91 it is identical as the internal diameter of tank body 1.
Working principle: liquid crystal material liquid and Liquid crystalline extraction agent are discharged into tank from first charging aperture 5 and second charging aperture 6 respectively
First charging aperture 5 and the concatenated valve 14 of second charging aperture 6, supersonic generator are closed in the inner cavity of body 1 respectively after the completion of being discharged into
13 work, mix liquid crystal material liquid and Liquid crystalline extraction agent effectively, then after static a period of time, so that mixed
Liquid layering is closed, then opens and extracts 11 concatenated valves 14 of outlet, due to the effect of piston plate 9, so that 1 inner cavity of tank body and piston
Space between plate 9 is in sealing state, and when so that extracting outlet 11 concatenated valves 14 opening, the liquid of 1 inner cavity of tank body is not
Can flow directly out, then cylinder 2 is shunk, so that piston plate 9 be driven to move downward so that the liquid crystal material layer of 1 inner cavity of tank body from
It extracts outlet 11 to be extruded, after liquid crystal material layer discharge, closes and extract 11 concatenated valves 14 of outlet, open 7 bottom of return pipe
Concatenated valve 14 is held, then cylinder 2 is shunk again, so that the mixing between the liquid crystal material layer and waste liquid layer of 1 inner cavity of tank body
Layer is extruded to go back to the inner cavity of flow container 8 from 1 inner cavity of tank body, and after mixed layer discharge, the concatenated valve in 8 bottom end of flow container is opened back in closing
Door 14 opens the concatenated valve 14 of waste outlet 12, and then cylinder 2 is shunk again, so that the waste liquid layer of 1 inner cavity of tank body is squeezed
Out, it is avoided by the liquid level of contraction control 1 inner cavity of tank body of cylinder 2 to control the velocity of discharge of liquid when drain
Traditional extraction device relies on the valve 14 of discharge port merely only in drain to control, and causes the waste or discharge of liquid crystal material
Liquid crystal material in the problem of being contaminated with waste liquid open the gas valve 10 of 1 bottom end of tank body, cylinder 2 when being extracted again
Rise, so that piston plate 9 rises to 1 inner cavity top of tank body, be then shut off gas valve 10, then opens 7 top of return pipe
Valve 14 is extracted so that going back to mixed layer liquid reflux to the inner cavity of tank body 1 that flow container 8 stores, again so as to avoid liquid
The waste of brilliant raw material.
