[0024] It should be noted that the existing ceramic membrane equipment usually adopts a single filtering method to filter the fermentation broth to remove impurities and particulate matter; however, the ceramic membrane equipment directly purifies and filters, and large particles of impurities, except for the impurities and gel layer attached to the surface of the membrane, will affect the filtration performance of the membrane. This single filtering method often has problems such as poor filtration effect, unstable filtrate quality and low filtration efficiency; especially when processing large-scale fermentation broth, the fermentation broth is prone to precipitation and separation, and these problems are more prominent, making it difficult to meet the needs of modern industrial production. This solution uses multi-stage filtration and circulating filtration to achieve The invention realizes efficient impurity removal and purification of the fermentation liquid; in the liquid storage tank 3, large particles of impurities are effectively removed, and the fermentation liquid is stirred and mixed to achieve uniform distribution, avoiding precipitation and separation; in the first filter cartridge 601 and the second filter cartridge 602, small particles of impurities are effectively removed, and the purity and quality of the fermentation liquid are improved; at the same time, the design of the circulation pipe 610 enables the liquid after preliminary filtration to flow back into the liquid storage tank 3, thereby improving the utilization rate and filtration efficiency of the equipment; through the application of the equipment, the purity and quality of the fermentation liquid can be significantly improved, the production cost can be reduced and the product quality can be improved, providing strong support for the development of modern industrial production.

[0025] Specifically, in this embodiment, the scheme mainly includes a mobile base 1; a liquid storage tank 3 and a purification component arranged above the mobile base 1; the purification component includes a first filter cartridge 601 and a second filter cartridge 602 arranged on the mobile base 1; the fermentation liquid enters the liquid storage tank 3 through the feeding port 4; this process is usually driven by a pump or gravity to ensure that the fermentation liquid can enter the liquid storage tank 3 evenly; after the fermentation liquid is processed in the liquid storage tank 3, it enters the first filter cartridge 601 through a circulation pipe 610 connected to the discharge port 5, and in the first filter cartridge 601, the fermentation liquid is filtered again through a ceramic membrane filter 603 to remove larger particle impurities therein, and the filtered liquid flows out from the second feed port 605 and enters the second filter cartridge 602 for further purification, and the intercepted impurity filtrate is recovered to the liquid storage tank 3 through the third feed port 606 through the circulation pipe 610 to achieve circulation filtration;

[0026] The fermented liquid will be filtered again through the second filter cartridge 602; the structure of the second filter cartridge 602 is similar to that of the first filter cartridge 601, and also includes a ceramic membrane filter 603. The pure liquid after two-stage filtration flows out from the fourth material port 607 of the second filter cartridge 602, and the sixth material port 609 is used to recover the filtrate containing a small amount of impurities;

[0027] The main working principle of the ceramic membrane filter 603 is to use the difference in membrane pore size to separate substances of different sizes. The membrane with a pore size larger than the pore size of the impurity molecules can block the impurities and allow D-pantothenate calcium molecules to pass through, thereby achieving separation, removing impurities and purifying the fermentation liquid, and improving the purity and quality of the fermentation liquid; at the same time, the design of the circulation pipe 610 allows the liquid after preliminary filtration to flow back into the liquid storage tank 3, thereby improving the utilization rate and filtration efficiency of the equipment.

[0028] In a further preferred embodiment of the present invention, Figure 5 As shown, a filter screen 7 is arranged at the upper position of the inner cavity of the liquid storage tank 3, and the filter screen 7 is arranged at an inclination, wherein a slag collecting trough 8 is arranged on the lower side of the filter screen 7.

[0029] In this embodiment, large particles of impurities are filtered through the filter screen 7 and intercepted in the slag collecting tank 8, and the fermentation liquid flows through the filter screen 7 into the lower ceramic membrane filter 603 for further purification; this structure is simple and effective, and can efficiently remove impurities in the fermentation liquid, while avoiding clogging of impurities and damage to the ceramic membrane filter 603, thereby extending the service life of the equipment; in addition, the design of the slag collecting tank 8 also facilitates the collection and treatment of impurities, thereby improving the cleanliness and maintenance convenience of the overall equipment.

[0030] In a further preferred embodiment of the present invention, Figure 5As shown, a stirring shaft 9 is installed at the lower position of the inner cavity of the liquid storage tank 3 through a bearing, and a plurality of stirring rods 10 are arranged on the stirring shaft 9. A servo motor 11 is arranged on the outer wall of the liquid storage tank 3, and the output end of the servo motor 11 is fixedly connected with the end key of the stirring shaft 9.

[0031] In this embodiment, the servo motor 11 can accurately control the rotation speed and direction of the stirring shaft 9, further improving the mixing effect and uniformity of the fermentation liquid, ensuring that the fermentation liquid is evenly distributed in the liquid storage tank 3, avoiding the precipitation and separation of the fermentation liquid, and improving the quality and stability of the fermentation liquid; at the same time, the rotation of the stirring rod 10 can increase the turbulence and mixing degree of the fermentation liquid, which helps to improve the filtering effect and efficiency of the ceramic membrane filter 603.

[0032] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a plurality of circulation pumps 12 and electric pressure regulating valves 13 are arranged on the circulation pipe 610 .

[0033] In this embodiment, the circulation pump 12 can provide sufficient power to ensure that the fermentation liquid flows smoothly in the circulation pipe 610, avoiding the retention and blockage of the fermentation liquid; at the same time, the electric pressure regulating valve 13 can accurately adjust the outlet pressure of the circulation pump 12, ensuring the pressure stability in the circulation pipe 610, and avoiding the influence of pressure fluctuations on the filtering effect.

[0034] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the mobile base 1 is also provided with a control box 14 electrically connected to the circulation pump 12 and the electric pressure regulating valve 13 .

[0035] In this embodiment, the control box 14 can remotely control and adjust the circulation pump 12 and the electric pressure regulating valve 13, so that the user can operate the equipment more conveniently.

[0036] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a plurality of evenly distributed support columns 2 are provided at the external positions of the liquid storage tank 3 and the first filter cartridge 601 and the second filter cartridge 602 , and the support columns 2 are fixed to the top of the mobile base 1 .

[0037] In this embodiment, the provision of the support column 2 can effectively disperse the weight of the equipment, reduce the pressure on the mobile base 1, and avoid deformation or damage of the mobile base 1 due to excessive weight of the equipment; at the same time, the support column 2 is fixed to the top of the mobile base 1, which further enhances the overall rigidity and stability of the equipment and improves the vibration resistance and load-bearing capacity of the equipment during operation.

[0038] Working principle: When the device is used, the fermentation liquid enters the liquid storage tank 3 through the feeding port 4; this process is usually driven by a pump or gravity to ensure that the fermentation liquid can enter the liquid storage tank 3 evenly;

[0039] Through the filtration of the filter screen 7, large particles of impurities are intercepted in the slag collecting tank 8, and the fermentation liquid flows through the filter screen 7 into the ceramic membrane filter 603 at the bottom for further purification; this structure is simple and effective, and can efficiently remove impurities in the fermentation liquid, while avoiding clogging of impurities and damage to the ceramic membrane filter 603, thereby extending the service life of the equipment; in addition, the design of the slag collecting tank 8 also facilitates the collection and treatment of impurities, thereby improving the cleanliness and maintenance convenience of the overall equipment;

[0040] The servo motor 11 can accurately control the rotation speed and direction of the stirring shaft 9, further improving the mixing effect and uniformity of the fermentation liquid, ensuring that the fermentation liquid is evenly distributed in the liquid storage tank 3, avoiding the precipitation and separation of the fermentation liquid, and improving the quality and stability of the fermentation liquid; at the same time, the rotation of the stirring rod 10 can increase the turbulence and mixing degree of the fermentation liquid, which helps to improve the filtering effect and efficiency of the ceramic membrane filter 603;

[0041] After being processed in the liquid storage tank 3, the fermentation liquid enters the first filter cartridge 601 through the circulation pipe 610 connected to the discharge port 5. In the first filter cartridge 601, the fermentation liquid is filtered again through the ceramic membrane filter 603 to remove larger particle impurities therein. The filtered liquid flows out from the second feed port 605 and enters the second filter cartridge 602 for further purification. The intercepted impurity filtrate is recovered to the liquid storage tank 3 through the circulation pipe 610 through the third feed port 606, thereby realizing circulation filtration.

[0042] The fermented liquid will be filtered again through the second filter cartridge 602; the structure of the second filter cartridge 602 is similar to that of the first filter cartridge 601, and also includes a ceramic membrane filter 603. The pure liquid after two-stage filtration flows out from the fourth material port 607 of the second filter cartridge 602, and the sixth material port 609 is used to recover the filtrate containing a small amount of impurities;

[0043] The ceramic membrane filter 603 has high selectivity and high permeability, and can effectively remove large particle impurities, gel layer and protein impurities in the fermentation broth, thereby reducing the impact on the membrane filtration performance; through the filtration effect of the ceramic membrane, the product purity and yield of the D-calcium pantothenate extraction process can be significantly improved; the pore size of the ceramic membrane and the physical and chemical properties of the membrane surface can be adjusted, which helps to control the molecular diffusion and transfer of D-calcium pantothenate; this helps to improve the crystallization quality and obtain a purer and more stable D-calcium pantothenate product;

[0044] In summary, ceramic membrane plays a positive role in improving protein impurities in the system and enhancing the product yield and crystal quality of D-pantothenate calcium extraction process.
