[0002] In the process of traditional Chinese medicine liquid production, a liquid sedimentation tank is used for centrifugal static sedimentation. After the sedimentation is completed, the supernatant and the bottom liquid are separated. However, in the prior art, the supernatant after sedimentation is usually extracted using a fixed-position pipette. This makes it easy for the bottom liquid to mix with the supernatant, affecting the quality of the extracted supernatant.

The medicine liquid sedimentation tank that is convenient for extracting supernatant liquid drives a rotating shaft and a centrifugal stirring block to centrifugally separate the medicine liquid through a rotating drive mechanism. After the medicine liquid is settled, the telescopic cylinder drives the filter screen to rise and fall and the extraction telescopic tube to extract the supernatant. At the same time, the filter screen can reduce the mixing of the medicine liquid at the bottom and the supernatant, thereby improving the quality of the extracted supernatant.

[0032] The utility model is further described in conjunction with the following embodiments.

[0033] Example 1.

[0034] like Figure 1-2 As shown, a medicinal liquid sedimentation tank for facilitating supernatant extraction comprises a sedimentation tank body 1, a positioning upper cover 2 is movably mounted on the sedimentation tank body 1, a rotation drive mechanism 3 is fixedly mounted at the top center of the positioning upper cover 2, an output end of the rotation drive mechanism 3 extends to the interior of the sedimentation tank body 1 and is fixedly connected to a rotating shaft 4, the bottom of the rotating shaft 4 is rotatably mounted with the sedimentation tank body 1, a rotating ring 5 is movably sleeved on the rotating shaft 4, and a filter screen 6 is fixedly mounted on the outside of the rotating ring 5.

[0035] The present application is used for centrifugal sedimentation of traditional Chinese medicine liquid and for facilitating the extraction of supernatant. First, the traditional Chinese medicine liquid is loaded through the sedimentation tank 1, and then the rotating shaft 4 is driven to rotate by the rotating drive mechanism 3 to achieve centrifugal stirring. At the same time, the filter screen 6 can be prevented from rotating with the rotation of the rotating shaft 4 by rotating the ring 5.

[0036] A telescopic cylinder 7 is fixedly installed on the positioning upper cover 2, and the output end of the telescopic cylinder 7 movably passes through the positioning upper cover 2 and is fixedly connected to the filter screen 6. An extraction telescopic tube 8 is also fixedly installed on the positioning upper cover 2, and the extraction end of the extraction telescopic tube 8 passes through the positioning upper cover 2 and extends to the top of the filter screen 6. The side wall of the extraction telescopic tube 8 is fixedly connected to the filter screen 6 through an L-shaped connecting rod 9.

[0037] The filter screen 6 can be driven to rise and fall by the telescopic cylinder 7, and at the same time, the extraction end of the extraction telescopic tube 8 is driven to move synchronously above the filter screen 6 by the L-shaped connecting rod 9. The other end of the extraction telescopic tube 8 is connected to an external extraction device to extract the supernatant to achieve a height change. When the supernatant is extracted, the filter screen 6 can prevent the liquid medicine at the bottom from mixing with the supernatant and entering the interior of the extraction telescopic tube 8.

[0038] Several positioning rings 10 are fixedly mounted on the rotating shaft 4 below the rotating ring 5 , and a centrifugal stirring block 11 is fixedly mounted on the positioning ring 10 . Reset springs 12 are connected between the rotating ring 5 and the positioning rings 10 , and between the positioning rings 10 on the outside of the rotating shaft 4 .

[0039] When the telescopic cylinder 7 drives the filter screen 6 to descend, it can drive the rotating ring 5 to press downward, and then press the several positioning rings 10 below through the return spring 12, so as to facilitate the extraction of the supernatant. After the extraction is completed, it can be restored to the original state and stirred and centrifuged again.

[0040] The rotation driving mechanism 3 includes a driving motor 31 and a reducer 32 that cooperate with each other. The output end of the reducer 32 extends to the interior of the sedimentation tank 1 and is fixedly connected to the rotating shaft 4.

[0041] The rotation driving mechanism 3 drives the output end of the reducer 32 to rotate through the output of the driving motor 31 , thereby driving the rotation of the rotating shaft 4 .

[0042] The outer wall of the filter screen 6 is in contact with the inner wall of the sedimentation tank body 1 .

[0043] The filter screen 6 covers the entire interior of the sedimentation tank 1 to prevent the liquid medicine settled at the bottom from mixing with the supernatant, thereby improving the extraction quality of the supernatant.

[0044] A feed inlet 13 and a discharge outlet 14 are respectively installed on the side wall and the bottom of the sedimentation tank body 1.

[0045] The Chinese medicinal liquid to be precipitated enters the sedimentation tank body 1 through the feed port 13 , and the precipitated medicinal liquid can be discharged through the discharge port 14 .

[0046] The utility model drives the rotating shaft 4 and the centrifugal stirring block 11 to centrifugally separate the liquid medicine through the rotating driving mechanism 3. After the liquid medicine settles, the telescopic cylinder 7 drives the filter screen 6 to rise and fall and the extraction telescopic tube 8 to extract the supernatant. At the same time, the filter screen 6 can reduce the mixing of the liquid medicine at the bottom and the supernatant, thereby improving the quality of the extracted supernatant.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
