The following describes a specific working procedure of a plant extract preparation extraction device according to the present application in combination with the above embodiments:
the upper weir plate 10 is adjusted before working:
the upper weir plate 10 is rotated according to the parameters of the two-phase liquid to be mixed, and the sizes of the light phase flow channel 15 and the heavy phase flow channel 14 between the upper weir plate 10 and the lower weir plate 9 are determined and then centrifugal extraction is carried out.
And (3) centrifugal extraction:
two phase liquids to be mixed are respectively introduced into the cylinder 2 through the light phase inlet pipe 3 and the heavy phase inlet pipe 8, and the two liquid phases which are not fused enter the interlayer of the cylinder 2 and the rotary drum 12, so that the two liquid phases are rapidly mixed by the rotation of the rotary drum 12. The mixed liquid enters the inside of the rotary drum 12 through a channel at the bottom of the rotary drum 12, and the liquid is gradually separated under the centrifugal force in the process of flowing from bottom to top in the rotary drum 12. The separation zone extends from the baffle ring 6 to the lower weir 9, ensuring that there is sufficient time for a liquid-liquid interface to form. The separated liquid-liquid phases enter the respective collection chambers through the light and heavy phase flow channels 14, respectively, and are discharged from the respective outlets, respectively.
When adjustment is needed:
1) When the light phase liquid in the light phase outlet pipe 1 is normal, and the heavy phase liquid in the heavy phase outlet pipe 11 contains a small amount of light phase liquid, the heavy phase weir plate is not required to be disassembled at this time, the heavy phase runner 14 can be adjusted only by rotating the upper weir plate 10 clockwise (in the direction from the upper weir plate 10 to the lower weir plate 9), the heavy phase runner 14 becomes smaller at this time, and the light phase runner 15 becomes larger, so that the flow of the heavy phase liquid in the heavy phase runner 14 is reduced, and meanwhile, the flow of the light phase liquid in the light phase runner 15 is increased, thereby eliminating the problem that the heavy phase liquid contains a small amount of light phase liquid.
2) When the heavy phase liquid in the heavy phase outlet pipe 11 is normal, but the light phase liquid in the light phase outlet pipe 1 contains a small amount of heavy phase liquid, the heavy phase weir plate does not need to be disassembled at the moment, the light phase flow channel 15 can be adjusted by rotating the upper weir plate 10 anticlockwise (in the direction from the upper weir plate 10 to the lower weir plate 9), at the moment, the light phase flow channel 15 becomes smaller, and the heavy phase flow channel 14 becomes larger, so that the flow quantity of the light phase liquid in the light phase flow channel 15 is reduced, and meanwhile, the flow quantity of the heavy phase liquid in the heavy phase flow channel 14 is increased, thereby eliminating the problem that the light phase liquid contains a small amount of the heavy phase liquid.
