[0022] The present invention is further described in detail below in conjunction with the embodiments: Example 1

[0023] like Figure 1-4 As shown, the utility model provides a dehydropregnenolone crystal separator, comprising a stirring mechanism 1, a shell mechanism 2 is fixedly connected to one side of the stirring mechanism 1, a refrigeration mechanism 3 is arranged inside the shell mechanism 2, the stirring mechanism 1 comprises a driving motor 11, a connecting rod 12 is fixedly connected to the output end of the driving motor 11, a first hollow plate 13 is fixedly connected to the surface of the connecting rod 12, a first spring 14 is fixedly connected to the inside of the first hollow plate 13, a second hollow plate 15 passes through the inside of the first hollow plate 13, the second hollow plate 15 is fixedly connected to the other end of the first spring 14, a second spring 16 is fixedly connected to the inside of the second hollow plate 15, and a brush 17 is fixedly connected to one end of the second spring 16;

[0024] Specifically, dehydropregnenolone and liquid are added into the shell 21, and then the drive motor 11 is started to drive the connecting rod 12 to rotate. The centrifugal force generated during the rotation drives the second hollow plate 15 and the brush 17 to move outward, thereby driving the first spring 14 and the second spring 16 to extend. The T-shaped rods at the top and bottom of the second hollow plate 15 move in the first hollow plate 13, thereby controlling the movement range of the second hollow plate 15. The second hollow plate 15 and the brush 17 move outward, so that the brush 17 is in contact with the inner wall of the shell 21, thereby scraping off the dehydropregnenolone on the inner wall of the shell 21, thereby increasing the mixing speed of the dehydropregnenolone and the liquid. After the dehydropregnenolone is dissolved, the drive motor 11 is turned off. Example 2

[0025] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the shell mechanism 2 includes a shell 21, the top of the shell 21 is fixedly connected to a support frame 22, the support frame 22 is fixedly connected to the drive motor 11, a heating plate 23 is arranged inside the shell 21, a heat insulation plate 24 is arranged at the bottom of the heating plate 23, the heat insulation plate 24 is located below the heating plate 23, a collecting box 25 is fixedly connected to the outer surface of the shell 21, a discharge pipe is fixedly connected inside the collecting box 25, and a control valve is movably connected inside the discharge pipe, and a supporting groove 26 is opened inside the collecting box 25;

[0026] Specifically, when it is necessary to heat dehydropregnenolone and liquid, the heating plate 23 is started to increase the temperature inside the shell, thereby cooperating with the stirring mechanism 1 to increase the mixing speed. The heat insulation plate 24 can prevent the temperature of the heating plate 23 from being transmitted to the collection box 25, thereby avoiding subsequent operations. After mixing, the heating plate 23 is turned off, and the liquid is cooled by the refrigeration mechanism 3 and drops to a certain temperature before crystals appear. As the cooling time increases, the liquid temperature decreases, the crystal growth rate increases, and the liquid that has not formed crystals falls into the collection box 25. The control valve is turned to make the discharge pipe in an open state to discharge the liquid. Example 3

[0027] like Figure 1-4As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the refrigeration mechanism 3 includes a connecting plate 31 and an electric push rod 34, the inside of the connecting plate 31 is fixedly connected with a filter screen 32, the left and right symmetrical fixed connection of the connecting plate 31 is connected with a support plate 33, the electric push rod 34 is fixedly connected to the left side of the collection box 25, the telescopic end of the electric push rod 34 is fixedly connected with a connecting frame 35, one end of the connecting frame 35 is fixedly connected with a U-shaped plate 36, the inside of the U-shaped plate 36 is provided with a condenser 37, a refrigerator 38 and a circulating water pump 39, the refrigerator 38 and the circulating water pump 39 are fixedly connected to the condenser 37, the U-shaped plate 36 is fixedly connected with a temperature conducting plate 30, and the temperature conducting plate 30 is attached to the filter screen 32 and the connecting plate 31;

[0028] Specifically, the mixed liquid is on the surface of the filter screen 32 and the heat conduction plate 30, and then the refrigerator 38 is started to cool the condensate in the condenser tube 37. The circulating water pump 39 drives the condensate to flow back and forth in the condenser tube 37, so that the temperature of the condenser tube 37 is more uniform. The heat conduction plate 30 introduces the temperature of the condenser tube 37 into the liquid to cool it. The longer the cooling time, the lower the temperature, and the higher the crystal growth rate. After the separation is completed, the electric push rod 34 is started to drive the U-shaped plate 36 and the heat conduction plate 30 to move to the left through the connecting frame 35. When the right side moves to the middle of the collection box 25, the electric push rod 34 is closed, and the liquid separated on the filter screen 32 can fall into the collection box 25. After the separation is completed, the connecting plate 31 is pulled to drive the filter screen 32 and the support plate 33 to move in the support groove 26, so as to ensure the stability of the connecting plate 31 and prevent the crystal from falling. After the connecting plate 31 is pulled out, the crystal can be collected.

[0029] The working principle of the dehydropregnenolone crystallizer is described in detail below.

[0030] like Figure 1-4As shown, dehydropregnenolone and liquid are added into the housing 21. When the dehydropregnenolone and liquid need to be heated, the heating plate 23 is started to increase the temperature inside the housing, and the driving motor 11 is started to drive the connecting rod 12 to rotate. The centrifugal force generated during the rotation drives the second hollow plate 15 and the brush 17 to move outward, thereby driving the first spring 14 and the second spring 16 to extend, so that the brush 17 is attached to the inner wall of the housing 21, and the dehydropregnenolone on the inner wall of the housing 21 is scraped off. After the dehydropregnenolone is dissolved, the driving motor 11 is turned off, and the refrigerator 38 is started. , the condensate in the condenser tube 37 is cooled, the circulating water pump 39 drives the condensate to flow back and forth in the condenser tube 37, and the temperature guide plate 30 introduces the temperature of the condenser tube 37 into the liquid to cool it. After the separation is completed, the electric push rod 34 is started to drive the U-shaped plate 36 and the temperature guide plate 30 to move to the left through the connecting frame 35. When the right side moves to the middle of the collection box 25, the electric push rod 34 is closed, and the liquid separated on the filter screen 32 can fall into the collection box 25. After the separation is completed, the connecting plate 31 is pulled out and the crystals can be collected.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
