Description

Technical Field

[0001] This utility model relates to the field of separation device technology, and in particular to a continuous centrifugal separation device for glycyrrhizic acid extract. Background Technology

[0002] Glycyrrhizic acid is one of the main active ingredients extracted from licorice, a traditional Chinese medicine. It possesses various biological activities such as anti-inflammatory, antioxidant, and hepatoprotective effects. In the pharmaceutical field, it is widely used to treat digestive system diseases, skin diseases, and in the preparation of immunomodulatory drugs. In the food industry, it can be used as a natural sweetener and antioxidant. It also plays an important role as a functional additive in the cosmetics industry. Therefore, achieving efficient extraction and purification of glycyrrhizic acid is of great significance for ensuring product quality, increasing added value, and expanding application areas. In its extraction process, centrifugation is a key operation, mainly used to complete solid-liquid separation (such as removing residues, cell debris, etc.) or liquid separation (such as removing impurities, solvents, or by-products) in the extract. Its separation effect directly affects the efficiency of subsequent purification and the purity and yield of the final product.

[0003] Currently, traditional centrifugal separation devices generally suffer from insufficient control over the flow state of materials when processing glycyrrhizic acid extracts, making it difficult to achieve effective separation of solid-liquid or liquid phases in complex systems. Due to the relatively simple equipment structure design, there is a lack of consideration for feed uniformity, flow rate control, and separation path optimization. In actual operation, phenomena such as incomplete separation, liquid entrainment of solid impurities, and unclear stratification of light and heavy phases are prone to occur.

[0004] Therefore, it is necessary to design a continuous centrifugal separation device for glycyrrhizic acid extract to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of traditional centrifugal devices, such as simple structure, difficulty in effectively controlling material flow, resulting in incomplete separation of glycyrrhizic acid extract and problems such as liquid entrainment and unclear stratification, this utility model provides a continuous centrifugal separation device for glycyrrhizic acid extract.

[0006] A continuous centrifugal separation device for glycyrrhizic acid extract includes a support base, a base plate, a connecting frame, a preliminary filter tank, a feed valve, a centrifugal separation tank, an annular slide bar, a discharge valve, a servo motor, a driving bevel gear, and a driven bevel gear. The base plate is fixedly connected to the top of the support base. A servo motor is fixedly connected to the right side of the bottom of the base plate. The output shaft of the servo motor is connected to the driving bevel gear. The driven bevel gear is rotatably connected to the center of the bottom of the base plate. A connecting shaft is fixedly connected to the center of the driven bevel gear. An annular slide bar is rotatably connected to the top of the base plate. The centrifugal separation tank is fixedly connected to the annular slide bar. The connecting shaft passes through the centrifugal separation tank and is fixedly connected to the bottom of the centrifugal separation tank. The driving bevel gear meshes with the driven bevel gear. A discharge valve is connected and communicates with the lower rear side of the centrifugal separation tank. A connecting frame is fixedly connected to the top of the base plate. A preliminary filter tank is installed on the top of the connecting frame. The bottom of the preliminary filter tank is connected to the top of the centrifugal separation tank. A feed valve is connected and communicates with the top of the preliminary filter tank.

[0007] Furthermore, it is particularly preferred that the filter also includes a filter plate, a collection frame, a stirring paddle, and a scraper. The filter plate is installed in the middle of the primary filter tank, and slag discharge grooves are opened in the front, back, left, and right directions of the filter plate. The collection frame is slidably connected to the lower part of the primary filter tank corresponding to the slag discharge grooves. The collection frame is located below the slag discharge grooves. The connecting shaft passes through the primary filter tank and is fixedly connected to the stirring paddle in the middle. The top of the connecting shaft passes through the middle of the filter plate and is fixedly connected to the scraper. The scraper is in rotatable contact with the surface of the filter plate and is located at the upper part of the filter plate.

[0008] Furthermore, it is particularly preferred that the collection frame is made of filter material.

[0009] Furthermore, it is particularly preferred that the collection frames also include a transparent plate and a handle, with the transparent plate fixedly connected to the middle of the opposite ends of the collection frames, and the handle fixedly connected to the opposite ends of the collection frames.

[0010] Furthermore, it is particularly preferred that the device also includes a first observation window and a second observation window, with multiple first observation windows uniformly fixedly connected to the outer wall of the middle part of the preliminary filtration tank along the circumference, and multiple second observation windows uniformly fixedly connected to the outer wall of the middle part of the centrifugal separation tank along the circumference.

[0011] Furthermore, it is particularly preferred that the device also includes a polymer filter element, and a high-precision filter tank is connected and communicated with the rear of the discharge valve, with the polymer filter element installed inside the high-precision filter tank.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model uses a multi-stage separation structure that combines a preliminary filtration tank and a centrifugal separation tank, so that the glycyrrhizic acid extract can directly enter the high-speed centrifugation stage after completing the preliminary solid-liquid separation. This avoids the inefficiency problem caused by traditional intermittent operation and improves the overall processing capacity and production continuity.

[0013] 2. This utility model uses a servo motor to drive the active bevel gear, which in turn drives the driven bevel gear and the connecting shaft to rotate synchronously, thereby driving the centrifugal separator to operate at high speed. The power transmission is stable and the response speed is fast, ensuring the reliability and safety of the equipment during long-term operation.

[0014] 3. This utility model enhances material flowability by using a stirring paddle driven by a servo motor to avoid clogging; the synchronous rotation of the scraper concentrates impurities and pushes them to the slag discharge tank, effectively preventing filter residue accumulation and improving filtration efficiency and equipment operation stability.

[0015] 4. This utility model uses a collection frame made of filter material, which can effectively intercept solid residues without affecting the flow of liquid; at the same time, it is equipped with a handle and a transparent plate, which makes it convenient to pull out for cleaning and to observe the status, reducing maintenance difficulty and time cost.

[0016] 5.

Detailed Implementation

[0024] Example: A continuous centrifugal separation device for glycyrrhizic acid extract, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the system includes a support base 1, a base plate 2, a connecting frame 3, a preliminary filter tank 4, a feed valve 5, a centrifugal separator 6, an annular slide bar 62, a discharge valve 7, a servo motor 8, a driving bevel gear 9, and a driven bevel gear 10. The base plate 2 is screwed onto the top of the support base 1. The servo motor 8 is screwed onto the bottom right side of the base plate 2. The output shaft of the servo motor 8 is connected to the driving bevel gear 9. The driven bevel gear 10 is rotatably connected to the bottom center of the base plate 2. A connecting shaft is welded to the center of the driven bevel gear 10. 2. A ring-shaped slide bar 62 is rotatably connected to the top. A centrifugal separator 6 is connected to the ring-shaped slide bar 62 by welding. A connecting shaft passes through the centrifugal separator 6 and is connected to the bottom of the centrifugal separator 6 by welding. The driving bevel gear 9 meshes with the driven bevel gear 10. A discharge valve 7 is connected and communicated to the lower rear side of the centrifugal separator 6. A connecting frame 3 is installed on the top of the bottom plate 2 by screws. A preliminary filter tank 4 is installed on the top of the connecting frame 3. The bottom of the preliminary filter tank 4 is connected to the top of the centrifugal separator 6. A feed valve 5 is connected and communicated to the top of the preliminary filter tank 4.

[0025] like Figure 2 , Figure 3 and Figure 5 As shown, it also includes a filter plate 42, a collection frame 44, a transparent plate 441, a handle 442, a stirring paddle 45, and a scraper 46. The filter plate 42 is installed in the middle of the primary filter tank 4. The filter plate 42 has slag discharge grooves 43 in the front, back, left and right directions. The collection frame 44 is slidably connected to the lower part of the primary filter tank 4, corresponding to the position of the slag discharge groove 43. The collection frame 44 is made of filter screen material and is located below the slag discharge groove 43. The transparent plate 441 is glued to the middle of the opposite ends of the collection frame 44. The handle 442 is welded to the opposite ends of the collection frame 44. The connecting shaft passes through the primary filter tank 4 and is welded to the middle of the middle of the tank. The top of the connecting shaft passes through the middle of the filter plate 42 and is welded to the scraper 46. The scraper 46 rotates and contacts the surface of the filter plate 42 and is located on the upper part of the filter plate 42.

[0026] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, it also includes a first observation window 41, a second observation window 61, and a polymer filter element 72. Multiple first observation windows 41 are evenly connected to the outer wall of the middle part of the preliminary filtration tank 4 by adhesive bonding along the circumference. Multiple second observation windows 61 are evenly connected to the outer wall of the middle part of the centrifugal separation tank 6 by adhesive bonding along the circumference. A high-precision filter tank 71 is connected and communicated to the rear of the discharge valve 7. A polymer filter element 72 is installed inside the high-precision filter tank 71.

[0027] When using this device, first, place it on a stable operating platform, ensuring the support base 1 is secure. Check through the transparent plate 441 to ensure the collection frame 44 is empty and the slag discharge trough 43 is unobstructed. Connect the power supply, open the feed valve 5, and slowly inject the glycyrrhizic acid extract into the preliminary filter tank 4. Start the servo motor 8. The extract undergoes preliminary solid-liquid separation through the middle filter plate 42. Larger particles are trapped on the upper layer of the filter plate 42. During filtration, the servo motor 8 drives the active bevel gear 9 to rotate, which in turn drives the driven bevel gear 10 to rotate, thereby driving the connecting shaft to rotate the stirring paddle 45 and scraper 46 synchronously. The stirring paddle 45 enhances material flowability and improves filtration efficiency. The scraper 46 concentrates the trapped impurities along the surface of the filter plate 42 and pushes them into the corresponding slag discharge trough 43 below, where they finally fall into the collection frame 44 for centralized collection. The collection frame 44 is made of filter screen material, which can effectively collect solid residues without affecting the continued downward flow of the liquid. At the same time, the extract after preliminary filtration flows into the centrifugal separator 6, where the servo motor... Driven by 8, the active bevel gear 9 drives the driven bevel gear 10 to rotate at high speed, thereby driving the connecting shaft and the centrifugal separator 6 to rotate synchronously at high speed. The centrifugal force generated by the high-speed rotation causes the different density components in the liquid to separate: the heavy phase (such as impurities) is deposited on the tank wall, and the light phase (target product) gathers in the central area. The separated liquid is discharged through the discharge valve 7 at the rear and further enters the high-precision filter tank 71. The polymer filter element 72 performs deep filtration on the liquid, removes residual small impurities, and further improves the purity of the product. The outer walls of the preliminary filter tank 4 and the centrifugal separator 6 are respectively equipped with multiple first observation windows 41 and second observation windows 61, which facilitates the operator to observe the internal operating status in real time and adjust the process parameters in a timely manner. After the processing is completed, the servo motor 8 is turned off and the equipment is stopped. The handle 442 is pulled out to remove the collection frame 44 and clean the impurities and residues inside. The first observation window 41 and the second observation window 61 are used to check whether there are any residues in the tank. If necessary, cleaning and maintenance are performed. Then, the feed valve 5 and the discharge valve 7 are closed, the power is cut off, and the equipment is properly stored for the next use.
