[0048] The following reference Figures 1-7 The centrifugal extractor provided in the embodiments of the present invention is described.

[0049] A centrifugal extractor, such as Figures 1-7 As shown, it includes an outer shell 210 and a first shell 220. The first shell 220 is provided with a sixth chamber 251, which can store the mixture. The rotation of the first shell 220 can drive the mixture in the sixth chamber 251 to rotate, and centrifuge the mixture to extract the heavy phase liquid and the light phase liquid.

[0050] The upper end of the first housing 220 is provided with a first flow channel 224 and a second flow channel 225.

[0051] The sixth chamber 251 is connected to the external environment through the first flow channel 224, and the heavy phase liquid is discharged through the first flow channel 224.

[0052] The sixth chamber 251 is connected to the external environment through the second flow channel 225, and the light phase liquid is discharged through the second flow channel 225.

[0053] The first housing 220 is also provided with a fifth chamber 227. The first flow channel 224 discharges the light phase liquid mixed in the heavy phase liquid into the fifth chamber 227, and the second flow channel 225 discharges the heavy phase liquid mixed in the light phase liquid into the fifth chamber 227. The mixed liquid in the fifth chamber 227 re-enters the sixth chamber 251.

[0054] The first flow channel 224 is provided with a fourth channel 231 and a fifth channel 232, and the second flow channel 225 is connected to the fifth chamber 227 through the fourth channel 231.

[0055] The outer casing 210 is provided with a first chamber 211 and a first channel 212. The first flow channel 224 is connected to the first chamber 211 through a fifth channel 232, and the first chamber 211 is connected to the external environment through the first channel 212.

[0056] The heavy phase liquid in the first flow channel 224 flows into the first chamber 211 through the fifth channel 232 and flows out of the outer shell 210 through the first channel 212. A small amount of light phase liquid mixed with the heavy phase liquid in the first flow channel 224 flows into the fifth chamber 227 through the fourth channel 231.

[0057] The second flow channel 225 is provided with a sixth channel 233 and a seventh channel 234.

[0058] The first housing 220 is also provided with a fourth chamber 226 for storing the light phase liquid discharged from the first flow channel 224.

[0059] The second flow channel 225 is connected to the fourth chamber 226 through the seventh channel 234, and the second flow channel 225 is connected to the fifth chamber 227 through the sixth channel 233; the light phase liquid in the second flow channel 225 flows into the fourth chamber 226 through the seventh channel 234, and the heavy phase liquid mixed in the light phase liquid in the first flow channel 224 flows into the fifth chamber 227 through the sixth channel 233.

[0060] The outer casing 210 also includes a second chamber 213 and a second channel 214. The second chamber 213 is connected to the external environment through the second channel 214. The first casing 220 is provided with an eighth channel 241. The fourth chamber 226 is connected to the second chamber 213 through the eighth channel 241. The separated light phase liquid is discharged from the outer casing 210 through the second channel 214.

[0061] The first housing 220 also includes a ninth channel 242, and the outer shell 210 also includes a third chamber 215 and a third channel 216; the fifth chamber 227 is connected to the third chamber 215 through the ninth channel 242, and the third chamber 215 discharges the mixed liquid through the third channel 216. The mixed liquid discharged from the fifth chamber 227 flows into the sixth chamber 251 for re-centrifugation and extraction.

[0062] A fifth chamber 227 is set up to collect the mixed liquid from the heavy phase liquid and the light phase liquid that was not completely extracted by centrifugation. The mixed liquid is then transported back to the sixth chamber 251 through the fifth chamber 227 for centrifugation extraction again, thereby improving the effect of centrifugation extraction.

[0063] The centrifugal extractor of the present invention can be applied to the centrifugal extraction in the preparation of tri-n-butyl butyryl citrate, and can also be applied to centrifugal extraction in other fields.

[0064] In one embodiment, such as Figures 4-5 As shown, the first flow channel 224 has a first inlet position and a first outlet position. The first inlet position is where the heavy phase liquid enters the first flow channel 224, and the first outlet position is where the heavy phase liquid exits the first flow channel 224. From the first inlet position to the first outlet position, the flow channel height of the first flow channel 224 gradually decreases, and the flow channel width of the first flow channel 224 gradually increases, which is beneficial to the centrifugal stratification of the liquid in the first flow channel 224.

[0065] The first flow channel 224 has the narrowest width at the first inlet position compared to other positions, and the highest height compared to other positions. This allows the outermost heavy phase liquid in the first shell 220 to enter the first flow channel 224, reducing the amount of mixed liquid entering the first flow channel 224 and improving the centrifugal quality of the liquid. The first flow channel 224 also has the widest width at the first outlet position compared to other positions, and the lowest height compared to other positions. This facilitates further stratification of the liquid in the first flow channel 224 and allows a small amount of light phase liquid mixed with the heavy phase liquid in the first flow channel 224 to flow into the fifth chamber 227.

[0066] In one embodiment, such as Figures 4-5 As shown, the second flow channel 225 has a second inlet position and a second outlet position. The second inlet position is where the light phase liquid enters the second flow channel 225, and the second outlet position is where the light phase liquid exits the second flow channel 225. From the second inlet position to the second outlet position, the flow channel height of the second flow channel 225 gradually decreases, and the flow channel width of the second flow channel 225 gradually increases, which is beneficial to the centrifugal stratification of the liquid in the second flow channel 225.

[0067] The second flow channel 225 has the narrowest width at the second inlet position compared to other positions, and the highest height compared to other positions. This allows the lighter phase liquid near the center of the first shell 220 to enter the second flow channel 225, reducing the amount of mixed liquid entering the second flow channel 225 and improving the centrifugal quality of the liquid. The second flow channel 225 has the widest width at the second outlet position compared to other positions, and the lowest height compared to other positions. This facilitates further stratification of the liquid in the second flow channel 225 and allows a small amount of heavier phase liquid mixed with the lighter phase liquid in the second flow channel 225 to flow into the fifth chamber 227.

[0068] In one embodiment, such as Figures 6-7 As shown, a rotating plate 223 is provided in the sixth chamber 251. The rotation of the rotating plate 223 can drive the mixture in the sixth chamber 251 to rotate.

[0069] The rotating plate 223 has a rectangular cross-section with its long side set vertically. The end face of the rotating plate 223 contacts the mixture to the maximum extent, so that the rotating plate 223 can drive the mixture to rotate more effectively.

[0070] Furthermore, such as Figures 4-7 As shown, it also includes a tenth channel 260, which is located between the first flow channel 224 and the second flow channel 225 and is surrounded by a rotating plate 223 and a first housing 220. The first housing 220 rotates to centrifuge and extract the mixture, causing the mixture to separate into a heavy phase liquid layer, a mixed layer of heavy phase liquid and light phase liquid, and a light phase liquid layer. The mixed layer of heavy phase liquid and light phase liquid returns to the sixth chamber 251 through the tenth channel 260 for re-centrifugation and extraction, thus preventing the mixed liquid from entering the first channel 212 and the second channel 214.

[0071] Furthermore, such as Figures 6-7 As shown, a second shaft 270 is provided in the sixth chamber 251. The second shaft 270 is arranged along the axis of the first housing 220. One end of the second shaft 270 is fixedly connected to the first housing 220. The rotation of the first housing 220 drives the second shaft 270 to rotate. The rotating plate 223 is in contact with the inner wall of the first housing 220. At the same time, the rotating plate 223 is fixedly connected to the second shaft 270. The rotation of the second shaft 270 can drive the rotating plate 223 to rotate.

[0072] Furthermore, a guide plate 253 is provided inside the first housing 220. The guide plate 253 is a circular plate. One end of the second shaft 270 is fixedly connected to the first housing 220, and the other end of the second shaft 270 is fixedly connected to the guide plate 253. The guide plate 253 is located at the outlet of the mixture entering the sixth chamber 251. When the mixture initially enters the sixth chamber 251, the guide plate 253 brings the mixture closer to the inner wall of the first housing 220, so that the mixture can obtain a greater rotation speed and promote the centrifugal stratification of the mixture.

[0073] In one embodiment, such as Figures 1-7 As shown, it includes an outer shell 210, a first shell 220 disposed inside the outer shell 210, a seventh chamber 252 disposed at the bottom of the outer shell 210, a third flow channel 228 disposed in the first shell 220, and a sixth chamber 251 and a seventh chamber 252 connected through the third flow channel 228; the seventh chamber 252 provides a mixture to the sixth chamber 251 through the third flow channel 228; the seventh chamber 252 is provided with a recovery port 219, through which the mixture in the fifth chamber 227 enters the seventh chamber 252.

[0074] The outer casing 210 also includes a light phase liquid inlet 217 and a heavy phase liquid inlet 218. The light phase liquid enters the seventh chamber 252 of the outer casing 210 through the light phase liquid inlet 217, and the heavy phase liquid enters the seventh chamber 252 of the outer casing 210 through the heavy phase liquid inlet 218.

[0075] The ninth channel 242 is connected to the recovery port 219 via a hose, allowing the mixed liquid in the sixth chamber 251 to enter the seventh chamber 252 through the hose, thus enabling the mixed liquid to be centrifuged and extracted again. This eliminates the need to use multiple centrifuges in series, reducing operating and maintenance costs.

[0076] In one embodiment, such as Figures 2-7 As shown, a stirring plate 222 is fixedly connected to the lower part of the first housing 220. The rotation of the first housing 220 can drive the stirring plate 222 to rotate, and the rotation of the stirring plate 222 can stir the mixture in the seventh chamber 252.

[0077] During use, the light phase liquid enters the seventh chamber 252 of the outer shell 210 through the light phase liquid inlet 217, and the heavy phase liquid enters the seventh chamber 252 of the outer shell 210 through the heavy phase liquid inlet 218. The stirring plate 222 rotates to make the light phase liquid and the heavy phase liquid in the seventh chamber 252 mix more thoroughly.

[0078] In one embodiment, such as Figures 2-7As shown, it includes an outer shell 210, a first shell 220 disposed inside the outer shell 210, the first shell 220 being a cylindrical shell, the outer surface of the first shell 220 being in contact with the inner surface of the outer shell 210, and the first shell 220 being rotatable relative to the outer shell 210.

[0079] In one embodiment, such as Figures 2-7 As shown, it also includes a power assembly that provides power for the rotation of the first housing 220.

[0080] The power assembly includes a drive motor 110 and a first shaft 221. One end of the first shaft 221 is fixedly connected to the first housing 220. The housing 210 is provided with a through hole. The other end of the first shaft 221 passes through the through hole and is fixedly connected to the output shaft of the drive motor 110. The drive motor 110 drives the first housing 220 to rotate through the first shaft 221.

[0081] During use, the light phase liquid is pumped into the seventh chamber 252 of the outer casing 210 through the light phase liquid inlet 217, and the heavy phase liquid is pumped into the seventh chamber 252 of the outer casing 210 through the heavy phase liquid inlet 218. The drive motor 110 is started, causing the output shaft of the drive motor 110 to rotate. The rotation of the output shaft drives the first shaft 221 to rotate, and the rotation of the first shaft 221 drives the first casing 220 to rotate. This causes the mixture in the sixth chamber 251 to rotate. The rotation of the first casing 220 drives the second shaft 270 to rotate, and the rotation of the second shaft 270 drives the rotating plate 223 to rotate, promoting the centrifugal extraction of the mixture.

[0082] In one embodiment, it also includes a power assembly that provides power for the rotation of the first housing 220.

[0083] The power assembly includes a drive motor 110 and a drive gear. The outer wall of the first housing 220 is provided with meshing teeth. The output shaft of the drive motor 110 is fixedly connected to the drive gear. The drive gear meshes with the meshing teeth. The rotation of the drive motor 110 can drive the drive gear to rotate. The rotation of the drive gear can drive the first housing 220 to rotate. The rotation of the first housing 220 can centrifuge and extract the mixture in the sixth chamber 251.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
