Description

Technical Field

[0001] This utility model relates to the technical field of plant component extraction equipment, and in particular to a separation device for total glycosides from Centella asiatica. Background Technology

[0002] Centella asiatica, also known as iron lamp grass, horse hoof grass, and thunder root, is a perennial herbaceous plant belonging to the Apiaceae family. Its main medicinal value lies in treating damp-heat jaundice, carbuncles, boils, and traumatic injuries. The pharmacologically active components in Centella asiatica are primarily saponins and their aglycones. Current herbal extraction processes use herbs as raw materials and, according to the intended use of the final product, employ physicochemical extraction and separation processes to selectively obtain and concentrate one or more active ingredients from the plant without altering their structure. This often involves separation and purification devices based on centrifuges and filters.

[0003] In existing technologies, the key technical points of herbal separation and filtration devices are: separating herbs through a liquid filtration device equipped with a filter body, filter cartridge, rotary cleaning mechanism, and dirt stripper. The core of using a filter lies in effectively retaining solid particles or suspended flocculent matter in a solid-liquid mixture using filter media such as filter screens or filter paper to achieve separation. However, in actual use, in herbal extracts, such as those from Centella asiatica, plant particles may not completely settle at the bottom of the centrifuge tube due to centrifugal force, but instead adhere to the filter media. After repeated use, the filter media becomes clogged with plant particles, leading to poor separation and purification effects.

[0004] Therefore, there is a need for a separation device for total glycosides from Centella asiatica that can improve the separation and purification effect of Centella asiatica extract. Utility Model Content

[0005] The main purpose of this invention is to provide a device for separating total glycosides from Centella asiatica, which aims to solve the problem of poor separation and purification effect of existing Centella asiatica extracts.

[0027] This utility model proposes a separation device 1000 for total glycosides of Centella asiatica, comprising: a tank 100, the tank 100 including a base 110 and a shell 120, the shell 120 having a cavity, and the shell 120 being connected to the base 110; a centrifuge cylinder 200, the centrifuge cylinder 200 including a filter cylinder 210 and a motor 220, the filter cylinder 210 being rotatably connected to one end of the base 110 and disposed inside the shell 120, the motor 220 being disposed at the top of the filter cylinder 210, and at least one end of the motor 220 passing through the shell 120; and a spray assembly 300, the spray assembly 300 being disposed inside the cavity of the shell 120, the spray assembly 300 being circumferentially arranged around the filter cylinder 210 at one end of the base 110, and the spray assembly 300 being connected to the filter cylinder 210.

[0028] In this embodiment, as Figures 1-3 As shown, the shell 120 inside the tank 100 has a cavity. A separation space is formed between the inner wall of the shell 120 and the outer surface of the filter cartridge 210. It can be understood that the filter cartridge 210 has an inlet at the top, and the shell 120 has an opening with a closed cover corresponding to the inlet. The filter cartridge 210 communicates with the external environment through the inlet. Driven by a motor 220, the filter cartridge 210 can rotate at high speed along the axis of the motor 220 within the shell 120, allowing the extract containing the solid material inside the filter cartridge 210 to be centrifuged and separated. Specifically, after opening the closed cover on the shell 120, the operator adds the Centella asiatica extract mixed with Centella asiatica fragments into the filter cartridge 210 through the inlet. Then, the filter cartridge 210 is started, causing it to rotate relative to the shell 120, separating the extract from the filter cartridge 210 into the separation space. The base 110 supports the centrifuge cylinder 200, the spray assembly 300, and the housing 120. The bottom of the base 110 is equipped with foot cups for shock absorption, ensuring the filter cylinder 210 can rotate horizontally during operation. One end of the spray assembly 300 passes through the housing 120 and is positioned circumferentially corresponding to the filter cylinder 210. The other end of the spray assembly 300 is located at the bottom of the housing 120, used to draw up the separated extract within the separation space. By re-spraying the separated extract back onto the filter cylinder 210, the spray assembly 300 achieves self-cleaning of the filter medium on the filter cylinder 210, preventing clogging of the filter pores and thus avoiding poor separation and purification effects.

[0029] In one embodiment, the spray assembly 300 includes a suction pipe 310, a spray pipe 330, and a liquid pump 320. The suction pipe 310 is connected to the spray pipe 330 through the liquid pump 320. One end of the suction pipe 310 passes through the bottom of the housing 120, and one end of the spray pipe 330 passes through the top of the housing 120.

[0030] In this embodiment, one end of the suction tube 310 extends through the bottom of the housing 120 to the separation space, and the other end of the suction tube 310 is connected to the liquid pump 320. The suction tube 310 is used to draw the extract from the separation space out of the separation space under the drive of the liquid pump 320. One end of the liquid pump 320 is connected to the suction tube 310, and the other end is connected to the spray tube 330. The spray tube 330 is arranged circumferentially inside the housing 120 along the filter cartridge 210. The spray tube 330 sprays the extract of Centella asiatica onto the filter cartridge 210 through the liquid pump 320 to clean the filter medium and its filter holes on the filter cartridge 210 and prevent Centella asiatica particles from clogging the filter medium.

[0031] In one embodiment, the spray pipe 330 includes a spray pipe 331 and a nozzle 332. One end of the spray pipe 331 passes through the housing 120, and the other end of the spray pipe 331 is connected to the liquid pump 320. The nozzle 332 is disposed on the end of the spray pipe 331 away from the liquid pump 320.

[0032] In this embodiment, the nozzle 331 is a hollow tube used to transport the extractant. One end of the nozzle 331 passes through the housing 120 and is connected to the liquid pump 320. The other end of the nozzle 331 is connected to the nozzle 332. There can be multiple nozzles 332. It is understood that multiple nozzles 332 can be connected in parallel with one nozzle 331 at the same time, or multiple nozzles 332 can be grouped. Different groups of nozzles 332 are connected to multiple nozzles 331 respectively, so as to realize regional liquid spraying for different heights above the ground of the filter cartridge 210.

[0033] In one embodiment, the spray pipe 330 is further provided with a rotating shaft 333, which is located on the end of the spray pipe 331 away from the liquid pump 320, and the nozzle 332 is rotatably connected to the spray pipe 331 through the rotating shaft 333.

[0034] In this embodiment, the rotating shaft 333 is located on the nozzle 331 at the end away from the liquid pump 320. The rotating shaft 333 is used to drive the nozzle 332 to rotate, which is equivalent to the nozzle 331, so that the nozzle 332 can increase the spray area on the side wall of the filter cartridge 210 and increase the spraying effect.

[0035] In detail, in this embodiment, the nozzle 332 is connected to the spray pipe 331 via a flexible hose, and the rotating shaft 333 is a toothed rotating shaft 333, which allows the operator to manually adjust the connection angle between the nozzle 332 and the spray pipe 331. It is understood that in another embodiment, the rotating shaft 333 can be connected to a rotation motor and a control module, allowing the operator to wirelessly control the connection angle between the nozzle 332 and the spray pipe 331. By adjusting the spray angle of the nozzle 332 and the spray rate of the liquid pump 320, the spray volume of the extract can be controlled to achieve different rinsing effects, avoiding excessive rinsing volume that could damage the filter media or insufficient rinsing volume that would fail to achieve the cleaning effect.

[0036] In one embodiment, the spray assembly 300 further includes a spray pipe 340, which is mounted on the top of the filter cartridge 210 and one end of the spray pipe 340 is connected to the liquid pump 320. The spray pipe 340 and the spray pipe 331 are arranged at an angle, and the spray pipe 340 is also provided with a plurality of through holes corresponding to the filter cartridge 210.

[0037] In this embodiment, the spray pipe 340 is mounted above the filter cartridge 210. The spray pipe 340 and the spray nozzle 331 are arranged vertically in space. The spray nozzle 331 and the nozzle 332 spray the extract horizontally to clean the side wall of the filter cartridge 210. The spray pipe 340 sprays the top of the filter cartridge 210 vertically to clean the top of the filter cartridge 210. At the same time, the spray pipe 340 is also provided with multiple through holes downward. The top of the filter cartridge 210 is provided with a water inlet corresponding to the through holes. The through holes can replenish the extract into the filter cartridge 210.

[0038] In one embodiment, the housing 120 further includes a stabilizer 121, which is disposed at the top of the housing 120 and has a groove corresponding to the top of the motor 220.

[0039] In this embodiment, a stabilizing frame 121 is disposed at the top of the housing 120. The stabilizing frame 121 has an inverted U-shaped structure. Specifically, the stabilizing frame 121 includes two legs and a crossbeam connecting the two legs. The two legs are respectively disposed at both ends of the top of the housing 120. A groove is provided at the bottom of the crossbeam corresponding to the position of the motor 220 to accommodate the end of the motor 220 away from the housing 120, thereby fixing the motor 220 and reducing the impact of vibration generated by the motor 220 during operation on the housing 120, achieving the technical effect of protecting the housing 120. At the same time, the stabilizing frame 121 also facilitates the subsequent movement of the Centella asiatica total glycoside separation device 1000.

[0040] In one embodiment, the base 110 further includes a first limiting disk 111, and the housing 120 is provided with a second limiting disk 122 corresponding to the first limiting disk 111. The first limiting disk 111 is arranged on the base 110 around the filter cylinder 210 in the circumferential direction, and the second limiting disk 122 is arranged inside the housing 120 and around the filter cylinder 210 in the circumferential direction.

[0041] In this embodiment, the first limiting disk 111 is circumferentially disposed on the base 110 around the filter cartridge 210, and the second limiting disk 122 is disposed on the inner wall of the housing 120 corresponding to the first limiting disk 111. A limiting space is formed between the first limiting disk 111 and the second limiting disk 122, and the filter cartridge 210 is disposed in the limiting space. The first limiting disk 111 and the second limiting disk 122 are used to limit the filter cartridge 210 to prevent the filter cartridge 210 from derailing during centrifugation. It can be understood that the side of the first limiting disk 111 and the second limiting disk 122 near the filter cartridge 210 is provided with flexible hydrophobic material to reduce the vibration generated by the filter cartridge 210 during operation.

[0042] This invention features a centrifuge chamber inside the tank. The centrifuge chamber, through its included filter cartridge and motor, performs solid-liquid separation on the extract containing Centella asiatica material. Furthermore, this invention includes a spray assembly, which can recycle and re-separate the extract separated between the centrifuge chamber and the tank, improving the purity of the separated Centella asiatica total glycoside extract. The spray assembly also cleans the filter medium and filter pores of the filter cartridge, preventing the filter medium and pores from adhering to the side wall of the filter cartridge during centrifugation and causing blockage by Centella asiatica particles, thereby improving the separation and purification effect of the Centella asiatica extract.

[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
