Description

Technical Field

[0001] This utility model relates to the field of ferulic acid production process, and in particular to a ferulic acid extraction device based on a circulating pump. Background Technology

[0002] Ferulic acid is a phenolic acid compound with various physiological activities, including antioxidant, anti-inflammatory, and immunomodulatory effects. It is widely found in traditional Chinese medicinal herbs such as Angelica sinensis and Ligusticum chuanxiong, as well as in grain bran. In the pharmaceutical field, ferulic acid can be used as a raw material to prepare cardiovascular drugs. In the food industry, it can act as a natural antioxidant. In the cosmetics field, its antioxidant properties are also highly valued. Therefore, efficient extraction of ferulic acid is crucial for the development of related industries. Whether it is the demand for high-purity ferulic acid in scientific research experiments or large-scale industrial production, there is an urgent need for high-performance extraction equipment.

[0003] Existing ferulic acid extraction devices mostly use centrifugal pumps as power sources, combined with traditional static extraction tanks and simple pipeline circulation systems. The centrifugal pumps drive the liquid circulation through centrifugal force generated by high-speed rotation.

[0004] Although this structure can achieve basic extraction, it is prone to insufficient mixing of solvent and raw materials, uneven local concentration, resulting in low raw material utilization and incomplete extraction of ferulic acid. Therefore, a ferulic acid extraction device based on a circulating pump is proposed. Utility Model Content

[0009] Furthermore, the recovery assembly includes a distillation apparatus, one side of the outer wall of which is disposed at one end of the pipeline, and a condenser is disposed at the output end of the distillation apparatus.

[0010] Furthermore, a liquid storage tank is fixedly connected to one end of the condenser tube, and an inlet pipe is fixedly connected to the outer wall of the liquid storage tank.

[0011] Furthermore, the outer wall of the rotating shaft is rotatably connected to the inside of the premixing tank, and the outer wall of the spiral blade is rotatably connected to the inside of the premixing tank.

[0012] Furthermore, a recycling cover is provided on one side of the outer wall of the premix tank, and the outer wall of the recycling cover is rotatably connected to the top of the filter plate.

After the raw materials and solvent enter the premixing tank, the raw materials are crushed by spiral blades and the mixture of raw materials and solvent is transported, thereby improving the utilization rate of raw materials and reducing extraction time, thus improving the practicality of the device.

[0017] In this invention, liquid and material are separated by using a distillation apparatus, and the separated solvent is then directed to a storage tank via a condenser connected to the distillation apparatus, thereby achieving solvent recycling.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 and Figure 2This utility model provides an embodiment of a ferulic acid extraction device based on a circulating pump, comprising an extraction tank 1, which is a sealed stainless steel container used to hold raw materials and extraction solvent, providing a site for the extraction reaction. A pipe 2 is fixedly connected to the lower surface of the extraction tank 1, and a centrifugal pump 4 is fixedly connected to one end of the pipe 2. The centrifugal pump 4 drives the mixture to flow out of the extraction container, through the pipeline, and back into the container, forming forced convection and enhancing the mass transfer process of ferulic acid from the raw material to the solvent, thereby shortening the equilibrium time and increasing the extraction rate. A second pipe 5 is fixedly connected to the output end of the centrifugal pump 4. Pipeline 3 (7) is fixedly connected to the outer wall of pipe 5. One end of pipe 3 (7) is fixedly connected to a recovery component. One end of pipe 2 (5) is set on the inner wall of extraction tank 1. A pretreatment component is set on the upper surface of extraction tank 1, and a stirrer 23 is set on the lower surface of extraction tank 1. The mixture is stirred in extraction tank 1 by the stirrer 23, thereby accelerating the turbulence effect of the raw material and thus accelerating and improving the extraction rate of the raw material. A check valve 1 (3) is set on the outer wall of pipe 1 (2), a check valve 2 (6) is set on the outer wall of pipe 2 (5), and a drain valve 8 is set on the outer wall of pipe 3 (7). The check valve and the drain valve are used to control the passage of each pipe and realize the switching of the fluid transport path.

[0027] Refer to Figure 3 and Figure 4The pretreatment assembly includes a premixing tank 10, a spiral blade 11, and a filter plate 12. The lower surface of the premixing tank 10 is fixedly connected to the upper surface of the extraction tank 1. A motor 13 is fixedly connected to the upper surface of the premixing tank 10, and a rotating shaft 14 is fixedly connected to the output end of the motor 13. The outer wall of the rotating shaft 14 is fixedly connected to the inner wall of the spiral blade 11. The spiral blade 11 is used to crush the raw material, increase the specific surface area, and accelerate the release of ferulic acid. The spiral blade 11 uses rotation and stirring to initially mix the raw material with the solvent. The outer wall of the filter plate 12 is slidably connected to the inner wall of the premixing tank 10, and the spiral blade 11 is positioned above the filter plate 12. The filter plate 12 is used to classify the crushed raw material by particle size, remove excessively large particles, and ensure uniform particle size, thereby maximizing the contact area between the solvent and the raw material and reducing the risk of coarse particles clogging the pipes. The outer wall of the rotating shaft 14 is rotatably connected to the inside of the premixing tank 10, and the outer wall of the spiral blade 11 is rotatably connected to... Inside the premixing tank 10, a recovery cover 22 is provided on one side of the outer wall of the premixing tank 10. By opening the recovery cover 22, different filter plates 12 with different pore sizes can be replaced according to different raw materials. After pretreatment, the large particles blocked by the filter plates 12 can be recovered, crushed and reused by opening the recovery cover 22. One side of the outer wall of the recovery cover 22 is rotatably connected to the filter plates 12. A feed pipe 15 is fixedly connected to one side of the outer wall of the premixing tank 10, and a delivery pipe 17 is fixedly connected to the other side of the outer wall of the premixing tank 10. A weighing hopper 16 is fixedly connected to one end of the feed pipe 15, and a flow valve 18 is fixedly connected to the outer wall of the delivery pipe 17. One end of the delivery pipe 17 is fixedly connected to one side of the outer wall of the storage tank 19. The feed pipe 15 and the delivery pipe 17 are used to transport raw materials and solvents into the premixing tank 10. The weighing hopper 16 and the flow valve 18 can accurately control the input amount of raw materials and solvents to ensure that the ratio of raw materials and solvents is appropriate.

[0028] Reference Figure 5 The recycling component includes a distillation apparatus 9. One side of the outer wall of the distillation apparatus 9 is located at one end of the pipe 3 7. A condenser 21 is provided at the output end of the distillation apparatus 9. A liquid storage tank 19 is fixedly connected to one end of the condenser 21. An inlet pipe 20 is fixedly connected to the outer wall of the liquid storage tank 19. The extracted mixture is transported to the distillation apparatus 9 through the pipe 3 7 to achieve liquid-liquid separation. The separated solvent flows to the liquid storage tank 19 through the condenser 21 connected to the distillation apparatus 9, thereby realizing the recycling of the solvent.

[0029] Working principle: When extracting ferulic acid from raw materials, firstly, depending on the raw material, the filter plate 12 with different pore sizes is replaced by opening the recovery cover 22. After replacement, the raw material and solvent are added to the weighing hopper 16 and the inlet pipe 20 in proportion. The raw material and solvent enter the premixing tank 10 through the feed pipe 15 and the delivery pipe 17, respectively. At this time, the motor 13 is started, which drives the rotating shaft 14 and the spiral blades 11 on the rotating shaft 14 in the premixing tank 10 to rotate, thereby achieving the cutting and crushing of the raw material and the initial mixing of the raw material and solvent to form a mixture. During the rotation process, the mixture slowly enters the extraction tank 1, during which time... The mixture passes through filter plate 12, thereby intercepting large particles and maximizing the contact area between the solvent and the raw material. This reduces the risk of large particles clogging the pipes, improves the utilization rate of the raw material, and reduces the extraction time. After the mixture enters the extraction tank 1, the power to stirrer 23 and centrifugal pump 4 is turned on. Stirrer 23 agitates the mixture in extraction tank 1, thereby accelerating the turbulence effect of the raw material and thus accelerating and improving the extraction rate. At the same time, centrifugal pump 4 works, allowing the mixture in extraction tank 1 to flow back into extraction tank 1 through pipe 1 2, check valve 1 3, centrifugal pump 4, pipe 2 5, and check valve 2 6, thereby achieving cyclic extraction.

[0030] Secondly, after extraction is complete, close the check valve 6, open the drain valve 8, and then turn on the centrifugal pump 4. The mixture in the extraction tank 1 is then allowed to enter the distillation apparatus 9 through pipe 2, check valve 3, centrifugal pump 4, pipe 5, pipe 7, and drain valve 8. The distillation apparatus 9 is used to separate the liquid and the solid. The separated solvent is then directed to the storage tank 19 through the condenser 21 connected to the distillation apparatus 9, thereby achieving solvent recycling, effectively improving solvent utilization, and significantly reducing production costs and waste discharge.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
