Description

Technical Field

[0001] This utility model relates to the field of plant active ingredient extraction, and in particular to a membrane separation device for plant active ingredient extraction. Background Technology

[0002] Membrane separation devices for extracting plant active ingredients are specialized equipment for the efficient separation and purification of active components (such as polysaccharides, saponins, and flavonoids) from plants. Their core principle is selective permeation of membranes, achieving separation of components with different molecular weights through physical sieving. The device typically includes components such as a tube body, filter cartridge, clamping mechanism, collection device, and air jetting device. The filter cartridge is connected to the tube body via the clamping mechanism. It utilizes the membrane pore size to trap large molecular impurities, while active substances permeate through the membrane into the collection device. During this process, the air jetting device assists in cleaning the filter cartridge, reducing residue damage to the equipment and thus improving its service life and filtration efficiency.

[0003] In the prior art, compared with the Chinese utility model with announcement number CN221062299U, a membrane separation device for extracting plant active substances is disclosed. In the process of cleaning the filter device, the clamping mechanism is rotated to clamp the filter device, thereby improving the installation efficiency. However, in the operation of extracting plant active substances in such ultrafiltration membrane equipment, due to the nature of plant active extracts, the macromolecules after filtration will have a certain degree of viscosity. When backwashing, simply using backwashing pressure cannot effectively and timely clean the attached substances. If a suitable degree of re-cleaning is required, the backwashing time needs to be increased, thus affecting the working efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a membrane separation device for extracting plant active substances in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A membrane separation device for extracting plant active ingredients includes a mounting frame for installation and fixation, and an ultrafiltration mechanism for extracting plant active ingredients. The ultrafiltration mechanism is mounted on the mounting frame. The device also includes a backwashing auxiliary mechanism for improving the cleaning effect during backwashing of the ultrafiltration mechanism, as well as a linkage mechanism and a power component for providing power. The backwashing auxiliary mechanism is installed inside the ultrafiltration cartridge of the ultrafiltration mechanism. The backwashing auxiliary mechanism is externally connected to the linkage mechanism via a mating component. The power component is installed at the power input end of the linkage mechanism.

[0007] The backwashing auxiliary mechanism includes a bottom power plate, which is rotatably connected to the bottom of the inner side of the ultrafiltration cartridge. The bottom power plate has a through groove for liquid to pass through. The upper surface of the bottom power plate has a bottom actuating block for actuating the ultrafiltration membrane filter element. Several central actuating strips are arranged in a circular array on the upper end of the bottom power plate outside the bottom actuating block. A top support ring is connected to the top of the central actuating strips.

[0008] Preferably, the linkage mechanism includes a sealing shell, which is fixedly connected to the mounting bracket. Inside the sealing shell, a worm gear is separately provided corresponding to the ultrafiltration cartridge. The worm gear is rotatably connected to the outside of the ultrafiltration cartridge at a height corresponding to the bottom power plate. One end of the worm gear is engaged with a worm. Several worms are connected in series through a main shaft. The power end of the main shaft is connected to the power assembly.

[0009] Preferably, the mating components include passive magnetic blocks and active magnetic blocks. The passive magnetic blocks are arranged in a circumferential array on the outer circular end face of the bottom power disk, and the active magnetic blocks are arranged in a circumferential array on the inner wall of the worm gear.

[0010] Preferably, the bottom actuating block has a cylindrical structure, and the top of the bottom actuating block has a spherical structure, and the height of the bottom actuating block gradually increases from the inside to the outside.

[0011] Preferably, the bottom actuating block is made of rubber.

[0012] Preferably, the outer side of the central actuating strip is fitted with the inner wall of the ultrafiltration cartridge with a clearance.

[0013] Preferably, the central actuating bar has four bars, and the central actuating bar has a spiral structure. The outer material of the central actuating bar is rubber, and the inner part is provided with steel wire for support.

[0014] Compared with existing technologies, the beneficial effects are as follows:

[0015] When the ultrafiltration unit is backwashed, the linkage mechanism drives the backwashing auxiliary mechanism to start, which in turn moves the bottom and sides of the ultrafiltration membrane filter element, assisting the ultrafiltration membrane filter element in friction and shaking during backwashing, thereby improving the backwashing efficiency, improving the equipment's performance and service life.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-8 As shown, a membrane separation device for extracting plant active substances includes a mounting frame 1 for installation and fixation and an ultrafiltration mechanism 2 for extracting plant active substances. The ultrafiltration mechanism 2 is mounted on the mounting frame 1. It also includes a backwashing auxiliary mechanism 5 for improving the cleaning effect when backwashing the ultrafiltration mechanism 2, and a linkage mechanism 3 and a power component 4 for providing power. The backwashing auxiliary mechanism 5 is installed inside the ultrafiltration cartridge 21 of the ultrafiltration mechanism 2. The backwashing auxiliary mechanism 5 is connected to the linkage mechanism 3 through a mating component. The power input end of the linkage mechanism 3 is equipped with the power component 4.

[0030] The backwashing auxiliary mechanism 5 includes a bottom power plate 53, which is rotatably connected to the bottom of the inner side of the ultrafiltration cartridge 21. A through groove for liquid to pass through is formed on the bottom power plate 53. A bottom actuating block 54 for actuating the ultrafiltration membrane filter element 22 is formed on the upper surface of the bottom power plate 53. Several central actuating strips 52 are arranged in a circular array on the upper end of the bottom power plate 53 outside the bottom actuating block 54. A top support ring 51 is connected to the top of the central actuating strips 52.

[0031] In this embodiment, the linkage mechanism 3 includes a sealing shell 31, which is fixedly connected to the mounting bracket 1. Inside the sealing shell 31, a worm gear 34 is separately provided corresponding to the ultrafiltration cartridge 21. The worm gear 34 is rotatably connected to the outside of the ultrafiltration cartridge 21 at the height corresponding to the bottom power disk 53. One end of the worm gear 34 is engaged with a worm 33. Several worms 33 are connected in series through a main shaft 32. The power end of the main shaft 32 is connected to the power assembly 4.

[0032] In this embodiment, the cooperating components include passive magnetic blocks 55 and active magnetic blocks 56. The passive magnetic blocks 55 are arranged in a circumferential array on the outer circular end face of the bottom power disk 53, and the active magnetic blocks 56 are arranged in a circumferential array on the inner wall of the worm gear 34.

[0033] In this embodiment, the bottom agitator 54 has a cylindrical structure and a spherical top. The bottom agitator 54 gradually increases in height from the inside to the outside. The bottom agitator 54 is used to agitate and assist in cleaning the bottom of the ultrafiltration membrane filter element 22.

[0034] In this embodiment, the bottom actuating block 54 is made of rubber.

[0035] In this embodiment, the outer side of the central actuating strip 52 is fitted with the inner wall of the ultrafiltration cartridge 21 with a clearance. When backwashing is performed, the bottom power plate 53, the central actuating strip 52, and the top support ring 51 are driven to rotate. At this time, the spiral structure of the central actuating strip 52 is subjected to the twisting rotation at the bottom and the resistance at the top, and it contracts inward, thereby contacting the inner ultrafiltration membrane filter element 22. Then, the rotational power is used to rub and actuate the surface of the ultrafiltration membrane filter element 22, thereby improving the backwashing efficiency of the ultrafiltration membrane filter element 22.

[0036] In this embodiment, four central actuating bars 52 are provided, and the central actuating bars 52 have a spiral structure. The outer material of the central actuating bars 52 is rubber, and the inner part is provided with steel wire for support.

[0037] Working principle: When the ultrafiltration membrane filter element 22 is in the filtration operation, impurities and large molecular particles such as proteins will be adsorbed on the surface of the ultrafiltration membrane filter element 22. When the ultrafiltration membrane filter element 22 needs to be backwashed, the flushing liquid seeps out from the inside of the ultrafiltration membrane filter element 22 to the outside.

[0038] At this time, the power assembly 4 is activated, which drives the active magnetic block 56 inside the worm gear 34 to rotate through the main shaft 32, worm 33, and worm wheel 34. After the active magnetic block 56 rotates, it drives the passive magnetic block 55 to rotate through magnetic force. At this time, the bottom power disk 53 is driven to rotate. After the bottom power disk 53 rotates, it will first drive the bottom agitator 54 to agitate and rub the bottom of the ultrafiltration membrane filter element 22, thereby assisting in cleaning the surface of the ultrafiltration membrane filter element 22. At the same time, because the central agitator 52 of the spiral structure is subjected to the twisting rotation at the bottom and the resistance at the top, it will contract inward, thereby contacting the inner ultrafiltration membrane filter element 22. Then, it will use the rotational power to rub and agitate the surface of the ultrafiltration membrane filter element 22, and the water flow will also be assisted in rotating, which improves the flow of the large molecular particles that have been peeled off by the water flow, thereby improving the efficiency of backwashing.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
