[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a protein purification and impurity washing device, including a base 1. A rotating plate 2 is rotatably mounted on the top of one end of the base 1. Rotating cylinders 3 are symmetrically mounted on both sides of the top of the rotating plate 2. A filter cartridge 9 is installed inside the rotating cylinder 3 through a positioning mechanism. A lifting mechanism is provided below the filter cartridge 9 corresponding to the inside of the rotating cylinder 3. The lifting mechanism includes a fixed frame 14 and a movable cover 15. An L-shaped bracket 4 is fixedly mounted on the top of the other end of the base 1. A top cover 5 is movably mounted below the top of the L-shaped bracket 4 through a hydraulic rod 7. The top cover 5 is positioned above the rotating cylinder 3. The top cover 5 and the rotating cylinder 3 are designed separately. After the top cover 5 is separated from the rotating cylinder 3, it is convenient to remove the filter cartridge 9 from the inside of the rotating cylinder 3, thereby facilitating the cleaning of impurities without affecting the subsequent purification of proteins, thus improving the purification and impurity washing efficiency of proteins.

[0022] In this embodiment, the fixed frame 14 is fixedly installed at the bottom of the inner side of the rotating cylinder 3, and the movable cover 15 is movably installed on the outer side of the fixed frame 14. A spring 16 is fixedly installed between the inner top wall of the movable cover 15 and the bottom wall of the rotating cylinder 3. The filter cartridge 9 is placed on the top of the movable cover 15 and in close contact. The spring 16 is installed inside the fixed frame 14. A drain port 10 is fixedly installed on one side of the movable cover 15 corresponding to the inside of the rotating cylinder 3. The movable cover 15 can move upward under the elastic force of the spring 16, which facilitates lifting the filter cartridge 9 upward, thereby facilitating the removal of the filter cartridge 9 from the inside of the rotating cylinder 3 and facilitating subsequent cleaning of impurities inside the filter cartridge 9. The fixed frame 14 can limit the movable cover 15 and improve the stability of the movable cover 15.

[0023] In this embodiment, the positioning mechanism includes a fixing ring 19, which is fixedly disposed on the inner wall of the rotating cylinder 3. The fixing ring 19 has symmetrical insertion holes at both ends. Fixing blocks 17 are symmetrically fixedly disposed on the outer walls of both sides of the top of the filter cylinder 9. An insertion rod 18 is fixedly disposed at the bottom of the fixing block 17, and the bottom end of the insertion rod 18 is inserted into the insertion hole.

[0024] In this embodiment, the hydraulic rod 7 is fixedly mounted on the top of the L-shaped bracket 4. A mounting cover 6 is fixedly mounted on the bottom end of the output rod of the hydraulic rod 7. The upper cover 5 is rotatably limited and mounted on the bottom of the mounting cover 6. Limiting rods 8 are symmetrically fixed on both sides of the top of the mounting cover 6. The top ends of the limiting rods 8 are slidably mounted inside the L-shaped bracket 4. A servo motor 13 is fixedly mounted at the center of the inner top wall of the mounting cover 6. The output shaft of the servo motor 13 is fixedly connected to the top of the upper cover 5. A protrusion is fixedly mounted at the center of the bottom of the upper cover 5, and the protrusion is in contact with the top of the filter cartridge 9. A positioning rod 12 is symmetrically fixed at the bottom edge of the upper cover 5, corresponding to the outer side of the protrusion. The top of the rotating cylinder 3 is circularly provided with a positioning hole 11. The positioning rod 12 is inserted into the positioning hole 11. The limiting rod 8 can limit the mounting cover 6, improving the stability of the mounting cover 6. The mounting cover 6 and the upper cover 5 can be raised and lowered by the hydraulic rod 7, which facilitates the merging or separation of the upper cover 5 and the rotating cylinder 3. The positioning rod 12 and the positioning hole 11 facilitate the positioning of the upper cover 5. At the same time, the upper cover 5 can drive the rotating cylinder 3 to rotate, which facilitates the centrifugal separation of impurities.

[0025] When using this protein purification and washing device, the filter cartridge 9 is installed inside a rotating cylinder 3 away from the top cover 5 via a positioning mechanism, and the insertion rod 18 is inserted into the insertion hole. The insertion rod 18, the fixing ring 19, and the fixing block 17 facilitate the positioning of the filter cartridge 9. The protein raw material to be purified is added inside the filter cartridge 9. The rotating cylinder 3 and the rotating plate 2 are rotated, rotating the rotating cylinder 3 to the bottom of the top cover 5, and the other rotating cylinder 3 is away from the top cover 5. The hydraulic rod 7 drives the mounting cover 6 and the top cover 5 to descend. The top cover 5 drives the positioning rod 12 and inserts it into the positioning hole 11. The protrusion squeezes the filter cartridge 9. The filter cartridge 9 is compressed by the spring 16 through the movable cover 15, and the top of the rotating cylinder 3 is sealed by the top cover 5. The drain port 10 is located inside the filter cartridge 9. A valve is installed on the top. When the servo motor 13 is started, the servo motor 13 drives the top cover 5 to rotate. The top cover 5 drives the rotating cylinder 3 to rotate on the top of the rotating plate 2 through the positioning rod 12 and the positioning hole 11, which facilitates the centrifugation purification of protein raw materials. At the same time, the filter cylinder 9 and protein raw materials are placed in sequence inside the rotating cylinder 3 on the other side. After centrifugation, the hydraulic rod 7 drives the mounting cover 6 and the top cover 5 to rise, so that the rotating cylinder 3 is separated from the top cover 5. The movable cover 15 lifts the filter cylinder 9 upward under the elastic force of the spring 16, removes the filter cylinder 9 and filters the impurities inside it, which facilitates the cleaning of the filtered impurities. The rotating plate 2 can rotate the two rotating cylinders 3 and adjust them alternately, which can improve the efficiency of protein purification.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
