A phospholipid solution separation mechanism is arranged in the box body. The phospholipid solution separation mechanism is composed of a first rotating cylinder rotatably installed in the box body and a second rotating cylinder rotatably installed in the first rotating cylinder. Filter meshes are installed on the side walls of the first rotating cylinder and the second rotating cylinder; an annular groove and a first through hole are arranged at the bottom of the first rotating cylinder. A driving motor is fixedly installed in the box body. The output shaft of the driving motor is fixedly connected to the lower surface of the second rotating cylinder. An annular boss is fixedly installed on the lower surface of the second rotating cylinder; a rotary cylinder is fixedly installed inside the box body. A driving wheel is fixedly installed on the output shaft of the rotary cylinder. A driven wheel is fixedly installed on the upper surface of the first rotating cylinder. The driving wheel and the driven wheel are in meshing transmission; a feed pipe is communicated with the upper surface of the second rotating cylinder. A second through hole is arranged at the central position of the upper surface of the first rotating cylinder and the driven wheel. The feed pipe passes through the second through hole and communicates with the outside; a centrifugal separation device made by using the technical solution of the utility model, the phospholipid solution after extraction and purification with absolute ethanol undergoes three separations in total. The phospholipid solution initially reaches the second rotating cylinder for primary centrifugal separation, and then passes through the filter mesh and enters the first rotating cylinder for secondary centrifugal separation. The two rotating cylinders rotate in opposite directions. The two centrifugal separation operations ensure that the phospholipid solution and the insoluble substances are centrifugally separated as much as possible.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figure 1 - Figure 4 shown, a centrifugal separator for phospholipid purification includes a barrel 1, a separation chamber 2, an upper baffle 3, a lower baffle 4, an inclined surface annular groove 5, a separation plate 6, a phospholipid solution outlet pipe 7 and an insoluble matter discharge pipe 8. A separation chamber 2 is formed inside the barrel 1. An upper baffle 3 is installed at the bottom of the separation chamber 2. An inclined surface annular groove 5 is provided at the bottom of the separation chamber 2. A lower baffle 4 and a separation plate 6 are installed at the bottom of the inclined surface annular groove 5. A phospholipid solution outlet pipe 7 and an insoluble matter discharge pipe 8 are connected to the separation plate 6 and the inclined surface annular groove 5. The lower baffle 4 and the separation plate 6 are integrally designed, and the connection part between the lower baffle 4 and the separation plate 6 is designed in an arc shape;

[0022] The barrel 1 is the main part of the centrifugal separator. A separation chamber 2 is formed inside it, providing the necessary space for phospholipid purification. An upper baffle 3 is installed at the bottom of the separation chamber 2. Its main function is to prevent the phospholipid solution from directly impacting the separation plate 6 during centrifugation and effectively introduce the liquid into the inclined surface annular groove 5. An inclined surface annular groove 5 is also provided at the bottom of the separation chamber 2. This is the key part of the centrifugal separator. The design of the inclined surface annular groove 5 helps to collect the sediment generated during centrifugation at the bottom of the groove, facilitating subsequent processing. The lower baffle 4 and the separation plate 6 are installed at the bottom of the inclined surface annular groove 5. The design of these two parts is the core of the centrifugal separator; the lower baffle 4 and the separation plate 6 are integrally designed, and the connection part is in an arc design. This design not only enables the phospholipid solution to flow smoothly during centrifugation, but also the upper baffle 3 and the lower baffle 4 cooperate with each other to realize the liquid flowing into the inclined surface annular groove 5; the phospholipid solution outlet pipe 7 and the insoluble matter discharge pipe 8 are respectively connected to the separation plate 6 and the inclined surface annular groove 5; the phospholipid solution outlet pipe 7 is responsible for leading out the purified phospholipid solution, while the insoluble matter discharge pipe 8 is responsible for discharging the sediment generated during centrifugation; through these two pipes, the centrifugal separator realizes the effective separation of phospholipids and insoluble matters;

[0023] The upper and lower ends of the barrel 1 are respectively installed with a second driving device 10 and a first driving device 9. The first driving device 9 is mechanically sealed with the barrel 1, and the first driving device 9 is fixed to the barrel 1 by bolts. The first driving device 9 is fixed to the bottom barrel 12 by fasteners. The bottom of the separation chamber 2 is provided with a bottom barrel 12. The first driving device 9 is connected to the bottom barrel 12. The second driving device 10 is fixed to the barrel 1 by bolts. A bearing is provided at the connection between the output end of the second driving device 10 and the barrel 1. The first driving device 9 and the second driving device 10 have the same structure and are both composed of a servo motor and a reducer. The output end of the servo motor is connected to the reducer. A first filter screen 13 is installed on the barrel wall of the bottom barrel 12. The upper and lower ends of the barrel 1 are respectively installed with a second driving device 10 and a first driving device 9. This design enables the barrel 1 to obtain a stable driving force during operation. Especially for the first driving device 9, it adopts a mechanical sealing method with the barrel 1, effectively preventing leakage and pollution. Fixed by bolts, the connection between the first driving device 9 and the barrel 1 is both firm and reliable. To further enhance the structural stability, the first driving device 9 is also fixed to the bottom barrel 12 by fasteners. The connection between the bottom barrel 12 and the first driving device 9 enables the bottom barrel 12 to remain stable during operation. The second driving device 10 is fixed to the barrel 1 by bolts. This connection method not only ensures its stability. A bearing is provided at the connection between the output end of the second driving device 10 and the barrel 1. This design reduces friction and improves the smoothness and efficiency of the equipment operation. The first driving device 9 and the second driving device 10 have the same structure and are both composed of a servo motor and a reducer. The output end of the servo motor is connected to the reducer. This combination enables the driving device to not only provide powerful power but also achieve precise speed control. The accuracy and stability of the servo motor, combined with the speed reduction and torque increase function of the reducer, make this driving system both efficient and reliable.

[0024] The top of the separation chamber 2 is connected with a top barrel 14. The upper end opening of the top barrel 14 is a liquid inlet 11. A second filter screen 15 is installed on the side wall of the top barrel 14. The first filter screen 13 is fixed to the bottom barrel 12 by fasteners. The second filter screen 15 is installed on the top barrel 14 by fasteners. The top barrel 14 is designed as a narrow-mouth bottle. A splash-proof cover plate 16 is installed at the upper end opening of the bottom barrel 12. The splash-proof cover plate 16 is sleeved on the top barrel 14. The inner ring of the splash-proof cover plate 16 is divided into an upper ring and a lower ring. Both the upper ring and the lower ring are designed in a flared shape and are symmetrically arranged. A transmission device 17 is installed between the top barrel 14 and the second driving device 10. The transmission device 17 is composed of a transmission belt, a large roller shaft, and a small roller shaft. The large roller shaft is fixed to the top barrel 14 by drilling holes, and the small roller shaft is fixed to the output end of the second driving device 10 by drilling holes.

[0025] The working principle is as follows: Start the first driving device 9 and the second driving device 10 to provide stable driving force for the centrifuge through the servo motor and the reducer; when the barrel 1 reaches the predetermined speed, introduce the phospholipid solution into the top barrel 14 through the liquid inlet 11, and the phospholipid solution enters the separation chamber 2 under the action of centrifugal force; the phospholipid solution enters the top barrel 14 for the first centrifugation operation, and then enters the bottom barrel 12 for the second centrifugation operation. The two centrifugation rotation directions are opposite. The centrifuged liquid is guided by the upper baffle 3, flows into the inclined surface annular groove 5, and smoothly flows through the lower baffle 4 and the separation plate 6; under the action of centrifugal force, the insoluble substances in the phospholipid solution gradually precipitate at the bottom of the inclined surface annular groove 5, while the purified phospholipid solution is led out through the phospholipid solution outlet pipe 7; the insoluble substances are discharged through the insoluble substance discharge pipe 8 for subsequent treatment.
