AI Technical Summary
但是,现有的澄清设备内,滤膜往往设置在设备的底部,澄清过程中,过滤出的杂质会在滤膜上逐渐堆积,而滤膜上的滤孔极微小,因此,随着澄清处理的进行,过滤澄清的效率必然逐渐降低,且滤膜为柔性薄膜,不宜采用刷洗或刮洗等接触式清洁方式进行清理
该基于膜过滤的生物发酵液澄清设备,通过交替式顺逆旋转的过滤组件上的滤膜,实现了对生物发酵液进行过滤澄清处理的效果,在过滤组件正反旋转的过程中,两个滤膜可在过滤状态和反冲清洁状态之间反复切换,由此即可避免过滤出的杂质长时间附着在滤膜上造成遮挡,进而导致过滤澄清效率持续下降的问题。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of skin care product processing equipment, specifically to a bio-fermentation broth clarification device based on membrane filtration. Background Technology
[0002] Bio-fermentation broth used in skincare product manufacturing is a general term for probiotic fermentation broth, plant fermentation broth, and microbial metabolite fermentation broth. It has the advantages of being highly mild, rich in active ingredients, easily absorbed, and highly safe, and is widely used in the preparation of skincare products with moisturizing, repairing, and anti-aging functions.
[0003] When preparing skincare products using bio-fermentation broth as a raw material, a clarification step is necessary in the preparation process to improve raw material safety, optimize product performance, and ensure production stability. This step aims to remove exogenous impurities, microbial residues, and macromolecular contaminants from the bio-fermentation broth. During clarification, membrane filtration-based clarification equipment can not only retain small molecule active substances like peptides but also enrich them. However, in existing clarification equipment, the filter membrane is often located at the bottom of the device. During clarification, filtered impurities gradually accumulate on the membrane. Since the pores on the membrane are extremely small, the filtration efficiency inevitably decreases as the clarification process continues. Furthermore, the filter membrane is a flexible membrane and is not suitable for cleaning using contact cleaning methods such as brushing or scraping. To address these issues, this invention proposes a membrane filtration-based bio-fermentation broth clarification device. Utility Model Content
[0004] The purpose of this invention is to provide a membrane filtration-based biological fermentation broth clarification device to solve the above-mentioned problems.
[0005] This utility model achieves the above objectives through the following technical solutions: This utility model provides a biological fermentation broth clarification device based on membrane filtration, including a material tank for the biological fermentation broth to be clarified, a coaxial guide pipe inside the material tank, a number of filter components arranged in a ring array on the outside of the guide pipe, and an opening on the side wall of the guide pipe communicating with the inner cavity of the filter components. The filter assembly includes a support fixed on the feed tube, a filter membrane disposed on both sides of the support, and a cap. The cap is used to cooperate with the support and the filter membrane to form the inner cavity of the filter assembly. The top cover of the feed tank is equipped with a drive mechanism for driving the feed pipe and the filter assembly to rotate alternately in both directions. The filter assembly is used to filter the bio-fermentation liquid entering the feed pipe and to alternately backwash and clean the filter membranes on both sides by rotating in a clockwise direction.
[0006] As a further optimization of this utility model, the filter assembly also includes a positioning rod for installing the filter membrane and the cap. The positioning rod is mounted on the bracket, the filter membrane is provided with an insertion tube that cooperates with the positioning rod, and the cap is provided with a slot that cooperates with the positioning rod.
[0007] As a further optimization of this utility model, the top and bottom ends of the guide tube both penetrate the material barrel and are rotatably connected to the material barrel.
[0008] As a further optimization of this utility model, the drive mechanism includes a driven gear sleeved on the guide tube and driving gears located on both sides of the driven gear. Both driving gears are missing gears and rotate in opposite directions. The two driving gears alternately mesh with the driven gear.
[0009] As a further optimization of this utility model, the material barrel is provided with a feed pipe and a waste discharge pipe, and the bottom of the material barrel is provided with a discharge pipe that communicates with the guide pipe.
[0010] The beneficial effects of this utility model are as follows: This membrane filtration-based bio-fermentation broth clarification device achieves the effect of filtering and clarifying bio-fermentation broth through the filter membranes on the filter components that rotate alternately in both directions. During the forward and reverse rotation of the filter components, the two filter membranes can repeatedly switch between the filtration state and the backwash cleaning state, thereby avoiding the problem of impurities being attached to the filter membrane for a long time and causing blockage, which would lead to a continuous decline in filtration and clarification efficiency.

[0013] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0014] Example 1 like Figure 1-5 As shown, the membrane filtration-based bio-fermentation broth clarification device of this embodiment includes a material tank 1 for the bio-fermentation broth to be clarified. The material tank 1 is provided with a coaxial guide pipe 2. The outer side of the guide pipe 2 is provided with a plurality of filter components arranged in a ring array. The side wall of the guide pipe 2 is provided with an opening 8 that communicates with the inner cavity of the filter components. The filter assembly includes a support 3 fixed on the feed tube 2, a filter membrane 4 disposed on both sides of the support 3, and a cover 7. The cover 7 is used to cooperate with the support 3 and the filter membrane 4 to form the inner cavity of the filter assembly. The top cover of the feed tank 1 is equipped with a drive mechanism for driving the feed pipe 2 and the filter assembly to rotate alternately in both directions. The filter assembly is used to filter the bio-fermentation liquid entering the feed pipe 2 and to alternately backwash and clean the filter membranes 4 on both sides by rotating in a clockwise direction.
[0015] The specific operation method for clarifying the biological fermentation liquid using this clarification equipment is as follows: the biological fermentation liquid to be clarified is injected into the material tank 1. The biological fermentation liquid can pass through the filter membrane 4 and the port 8 in sequence into the feed pipe 2, and then be output through the feed pipe 2. The impurities in the biological fermentation liquid are blocked on the outside of the filter component and remain in the material tank 1. The output is the clarified biological fermentation liquid. After the drive mechanism is turned on, the feed pipe 2 and the filter assembly rotate alternately in both directions. During this process, on the one hand, the above-mentioned filtration and clarification process continues, and the rotational motion allows the bio-fermentation liquid to be clarified to pass through the filter membrane 4 more efficiently, which is beneficial to improving the clarification efficiency. On the other hand, the two filter membranes 4 on one filter assembly filter in opposite directions. Therefore, regardless of whether the filter assembly rotates clockwise or counterclockwise, the agitated bio-fermentation liquid passes through one filter membrane 4 in the forward direction into the inner cavity of the filter assembly. Subsequently, part of the filtered and clarified bio-fermentation liquid passes directly through the port 8 and is output through the feed pipe 2, while part passes through the other filter membrane 4 in the reverse direction under the drive of the directional fluid. During this process, one filter membrane 4 plays the role of filtration and clarification, while the other is in a state of backwashing and cleaning. The impurities attached to the filter membrane 4 can be remixed into the unclarified bio-fermentation liquid, thereby avoiding the problem of the filter membrane 4 being covered, which leads to a decrease in filtration and clarification efficiency.
[0016] As a further optimization of this embodiment, the filter assembly also includes a positioning rod 5 for installing the filter membrane 4 and the cover 7. The positioning rod 5 is disposed on the bracket 3, the filter membrane 4 is provided with an insertion tube 6 that cooperates with the positioning rod 5, and the cover 7 is provided with a slot that cooperates with the positioning rod 5. The filter membrane 4 is installed by inserting the corresponding tubes 6 on the positioning rods 5 from top to bottom. This ensures that the filter membrane 4 remains flat during the filtration and clarification process. The filter membrane 4 and the tubes 6 together seal both sides of the filter assembly. Then, align the slot on the cap 7 with the positioning rods 5 and place the cap 7 on the support 3 to complete the assembly of the filter assembly. After assembly, the bio-fermentation broth entering the inner cavity of the filter assembly must pass through the filter membrane 4 for filtration and clarification. After clarification, the filter assembly can be thoroughly disassembled and cleaned.
[0017] As a further optimization of this embodiment, the top and bottom ends of the guide pipe 2 both penetrate the material barrel 1 and are rotatably connected to the material barrel 1; The drive mechanism includes a driven gear 10 sleeved on the guide tube 2 and a drive gear 9 located on both sides of the driven gear 10. Both drive gears 9 are missing gears and rotate in opposite directions. The two drive gears 9 alternately mesh with the driven gear 10. In this embodiment, the driving components of both active gears 9 are motors. After being turned on, the two active gears 9 rotate continuously and mesh with the driven gears 10 in sequence, thereby driving the material guide tube 2 and the filter assembly to rotate alternately in both clockwise and counterclockwise directions.
[0018] In this embodiment, the material hopper 1 adopts a detachable top cover. The driven gear 10 and the guide tube 2 are detachably connected by the cooperation of the sleeve on the outside of the guide tube 2 and the slot on the driven gear 10. The top cover of the material hopper 1 and the drive mechanism can be removed by lifting it up.
[0019] As a further optimization of this embodiment, the material tank 1 is equipped with a feed pipe 11 and a waste discharge pipe 12, and the bottom of the material tank 1 is equipped with a discharge pipe 13 that communicates with the guide pipe 2. The connection and switching control of the above-mentioned pipes are realized through control valves. After the clarification treatment is completed, cleaning water is injected simultaneously from the top of the guide pipe 2 and the feed pipe 11 to rinse the clarification equipment in all directions. The rinsing wastewater is output through the guide pipe 2 and the waste discharge pipe 12.
[0020] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
