Description

Technical Field

[0001] This utility model relates to the field of oil-water separation equipment technology, and in particular to a high-efficiency oil-water separation and filtration device for skin care products. Background Technology

[0002] Skincare products, such as creams, lotions, and serums, are often complex mixtures of oil, water, active ingredients, and emulsifiers. During production, whether for formulation development, quality control, or production management, oil-water separation is frequently required in finished or semi-finished products to analyze ingredient stability, content ratios, or for further processing. Therefore, efficient and thorough oil-water separation is a crucial step in skincare product research and development. Currently, the industry primarily relies on the following methods for oil-water separation in skincare products: static stratification, heat-assisted static stratification, and conventional centrifugation. Among these, centrifugation is the most widely used method. Centrifuges generate centrifugal force far exceeding gravity, accelerating oil-water separation. While this method improves separation speed to some extent... However, for emulsion droplets or colloidal dispersions with tiny particle sizes, the above separation methods are insufficient to achieve complete separation using centrifugal force alone. Tiny droplets of the other phase may still remain in the separated oil or water phase, resulting in insufficient purity. Therefore, there is an urgent need for an oil-water separation device that integrates high efficiency, precision, gentleness, and automation to overcome the shortcomings of existing technologies and meet the modern skincare industry's production requirements for high quality, high efficiency, and high consistency. Utility Model Content

[0003] Therefore, it is necessary to provide a high-efficiency oil-water separation and filtration device for skin care products, addressing the technical problem that existing oil-water separation equipment for skin care products cannot achieve complete separation of the oil phase and water tank.

[0004] A high-efficiency oil-water separation and filtration device for skin care products is disclosed. The device includes a pretreatment module, a separation module, a filtration module, and a control module. The pretreatment module, the separation module, and the filtration module are connected in sequence by pipelines. The control module is electrically connected to the pretreatment module, the separation module, and the filtration module respectively.

[0005] The pretreatment module includes a PTC heating sleeve and a static mixer. The input end of the static mixer is connected to the storage unit of the material to be separated through a pipeline. The PTC heating sleeve is fitted outside the pipeline at the input end of the static mixer.

[0006] The separation module includes a centrifuge, the input of which is piped to the output of a static mixer.

[0007] The filtration module includes a hydrophobic membrane filter canister and a hydrophilic membrane filter canister. The input pipe of the hydrophobic membrane filter canister is connected to the light phase output port of the centrifuge; the input pipe of the hydrophilic membrane filter canister is connected to the heavy phase output port of the centrifuge.

[0008] In one embodiment, the pretreatment module further includes a raw material storage tank, the output pipe of which is connected to a static mixer, and a PTC heating sleeve is fitted outside the pipe between the raw material storage tank and the static mixer.

[0009] In one embodiment, the pretreatment module further includes a feed pump, which is located between the raw material storage tank and the static mixer. The input pipe of the feed pump is connected to the output of the raw material storage tank, and the output pipe of the feed pump is connected to the input of the static mixer. A PTC heating sleeve is fitted outside the pipe between the feed pump and the static mixer.

[0010] In one embodiment, the centrifuge described above is an intelligent variable frequency disc centrifuge, and the intelligent variable frequency disc centrifuge is electrically connected to the control module.

[0011] In one embodiment, the separation module further includes a light phase storage tank and a heavy phase storage tank. The input end of the light phase storage tank is connected to the light phase output port pipe of the centrifuge, and the output end pipe of the light phase storage tank is connected to the hydrophobic membrane filter tank. The input end of the heavy phase storage tank is connected to the heavy phase output port pipe of the centrifuge, and the output end pipe of the heavy phase storage tank is connected to the hydrophilic membrane filter tank.

[0012] In one embodiment, the separation module further includes a solid phase collector, the input pipe of which is connected to the solid phase output port of the centrifuge.

[0013] In one embodiment, the filtration module further includes a light phase transfer pump and a heavy phase transfer pump. The light phase transfer pump is disposed between the light phase storage tank and the hydrophobic membrane filter tank, and the input end of the light phase transfer pump is connected to the output end of the light phase storage tank via a pipeline, while the output end of the light phase transfer pump is connected to the input end of the hydrophobic membrane filter tank. The heavy phase transfer pump is disposed between the heavy phase storage tank and the hydrophilic membrane filter tank, and the input end of the heavy phase transfer pump is connected to the output end of the heavy phase storage tank via a pipeline, while the output end of the heavy phase transfer pump is connected to the input end of the hydrophilic membrane filter tank.

[0014] In one embodiment, the filtration module further includes a clean oil phase collection tank and a clean water phase collection tank, with the input end of the clean oil phase collection tank connected to the output end of the hydrophobic membrane filter tank via a pipeline; and the input end of the clean water phase collection tank connected to the output end of the hydrophilic membrane filter tank via a pipeline.

[0016] The aforementioned skincare product oil-water separation and filtration device actively physical conditions the materials through a pretreatment module consisting of a PTC heating jacket and a static mixer. The heating function effectively reduces the viscosity of skincare products (such as creams and lotions), breaking down the interaction forces between oil and water, thus significantly reducing subsequent separation resistance. The static mixer ensures uniform material temperature and properties, creating stable and consistent initial conditions for subsequent separation. Compared to traditional methods like room temperature standing or direct centrifugation, this pretreatment step significantly shortens the time required for the entire separation process. The device employs a two-stage tandem separation and filtration process using a centrifuge and hydrophilic / hydrophobic membrane filtration. The centrifuge efficiently completes the main separation of the oil, water, and solid phases, removing most incompatible components. Liquids and solid particles are then finely filtered through hydrophilic / hydrophobic membranes, achieving precise capture of micron- or even submicron-sized dispersed phases, resulting in extremely high purity oil and water phases. The entire system integrates multiple physical separation methods, including heating for viscosity reduction, three-phase centrifugation, and membrane precision filtration. The pretreatment module effectively handles high-viscosity serums and creams. For formulations containing small amounts of solid particles, the centrifuge can discharge them as solids, avoiding damage to subsequent membrane components or affecting liquid phase purity. The membrane filtration stage is specifically designed for stable micro-emulsions, thus greatly expanding the applicability of this separation and filtration device and meeting the oil-water separation needs of complex ingredients and diverse dosage forms in the skincare industry.

[0024] Please see Figure 1This utility model discloses a high-efficiency oil-water separation and filtration device for skin care products. The device includes a pretreatment module 1, a separation module 2, a filtration module 3, and a control module 4. The pretreatment module 1, separation module 2, and filtration module 3 are connected in sequence by pipelines, so that the skin care product materials sequentially pass through the pretreatment module 1 to complete the physical conditioning and viscosity reduction process, through the separation module 2 to complete the main separation power under the centrifugal force field, and through the filtration module 3 to complete the precise filtration process, in order to adapt to the oil-water separation work of skin care products with complex ingredients. The control module 4 is electrically connected to the pretreatment module 1, separation module 2, and filtration module 3 respectively, so as to realize the intelligent control of the entire high-efficiency oil-water separation and filtration device for skin care products. Specifically, the pretreatment module 1 includes a PTC heating sleeve 11 and a static mixer 12. The input end of the static mixer 12 is connected to the storage unit of the material to be separated via a pipe. The PTC heating sleeve 11 is fitted outside the pipe at the input end of the static mixer 12, thereby heating the material input to the static mixer 12. The material heated to the preset temperature is then statically mixed by the static mixer 12, achieving physical conditioning and viscosity reduction of the material. Correspondingly, the separation module 2 includes a centrifuge 21. The input end of the centrifuge 21 is connected to the output end of the static mixer 12 via a pipe, thereby conveying the material output from the static mixer 12 after mixing to the centrifuge 21. Centrifugal separation is performed, and the resulting light phase (oil phase), heavy phase (aqueous phase), and solid phase are output separately through three independent output ports of centrifuge 21. Correspondingly, the filtration module 3 includes a hydrophobic membrane filter tank 31 and a hydrophilic membrane filter tank 32. The input pipe of the hydrophobic membrane filter tank 31 is connected to the light phase output port of centrifuge 21, so that the light phase output from centrifuge 21 is filtered by the hydrophobic membrane filter tank 31 to obtain a clean oil phase. The input pipe of the hydrophilic membrane filter tank 32 is connected to the heavy phase output port of centrifuge 21, so that the heavy phase output from centrifuge 21 is filtered by the hydrophilic membrane filter tank 32 to obtain a clean aqueous phase, thereby completing the efficient oil-water separation and filtration process of skin care products.Based on the above setup, the high-efficiency oil-water separation and filtration device for skincare products in this solution uses a pretreatment module 1 consisting of a PTC heating sleeve 11 and a static mixer 12 to actively physical condition the materials. The heating function effectively reduces the viscosity of skincare products (such as creams and lotions), breaking down the interaction forces between oil and water, thus significantly reducing the resistance to subsequent separation. The static mixer 12 ensures the uniformity of material temperature and properties, creating stable and consistent initial conditions for subsequent separation. Compared to traditional room temperature standing or direct centrifugation, this pretreatment step can significantly shorten the time required for the entire separation process. The device employs a two-stage series separation and filtration process using a centrifuge 21 and a hydrophilic / hydrophobic membrane filter. The centrifuge 21 can efficiently complete the main separation of the oil, water, and solid phases. The system removes most incompatible liquids and solid particles, followed by fine filtration through hydrophilic / hydrophobic membranes, achieving precise capture of micron- or even submicron-sized dispersed phases, resulting in extremely high purity oil and water phases. The entire system integrates multiple physical separation methods such as heating for viscosity reduction, three-phase centrifugation, and membrane precision filtration. For high-viscosity serums and creams, the pretreatment module 1 can effectively handle them. For formulations containing a small amount of solid particles, the centrifuge 21 can discharge them as solids, avoiding damage to subsequent membrane components or affecting the purity of the liquid phase. The membrane filtration stage is specifically designed to process stable micro-emulsions, thereby greatly expanding the applicability of this separation and filtration device and meeting the oil-water separation needs of complex ingredients and diverse dosage forms in the skincare industry.

[0025] Furthermore, the pretreatment module 1 also includes a raw material storage tank 13. The output pipe of the raw material storage tank 13 is connected to the static mixer 12. The PTC heating sleeve 11 is sleeved on the outside of the pipe between the raw material storage tank 13 and the static mixer 12. Thus, the raw material storage tank 13 can be used to temporarily store the skin care product raw materials to be separated and filtered, and transport them to the static mixer 12.

[0026] Specifically, in one embodiment, the pretreatment module 1 further includes a feed pump 14, which is disposed between the raw material storage tank 13 and the static mixer 12. The input end pipe of the feed pump 14 is connected to the output end of the raw material storage tank 13, and the output end pipe of the feed pump 14 is connected to the input end of the static mixer 12. The PTC heating sleeve 11 is sleeved on the outside of the pipe between the feed pump 14 and the static mixer 12. Thus, the feed pump 14 can pump the skin care raw materials in the raw material storage tank 13 to the static mixer 12 in a metered manner.

[0027] Furthermore, the centrifuge 21 is an intelligent variable frequency disc centrifuge 21, and the intelligent variable frequency disc centrifuge 21 is electrically connected to the control module 4, thereby realizing the intelligent control of the centrifuge 21 by the control module 4.

[0028] Furthermore, the separation module 2 also includes a light phase storage tank 22 and a heavy phase storage tank 23. The input end of the light phase storage tank 22 is connected to the light phase output port pipe of the centrifuge 21, and the output end pipe of the light phase storage tank 22 is connected to the hydrophobic membrane filter tank 31. The input end of the heavy phase storage tank 23 is connected to the heavy phase output port pipe of the centrifuge 21, and the output end pipe of the heavy phase storage tank 23 is connected to the hydrophilic membrane filter tank 32, thereby realizing the material transfer between the centrifuge 21 and the filter unit.

[0029] Specifically, in one embodiment, the separation module 2 further includes a solid phase collector 24, the input end of which is connected to the solid phase output port of the centrifuge 21 to independently collect the separated solid phase.

[0030] Furthermore, the filtration module 3 also includes a light phase transfer pump 33 and a heavy phase transfer pump 34. The light phase transfer pump 33 is located between the light phase storage tank 22 and the hydrophobic membrane filter tank 31, and the input end of the light phase transfer pump 33 is connected to the output end of the light phase storage tank 22, while the output end of the light phase transfer pump 33 is connected to the input end of the hydrophobic membrane filter tank 31, thereby realizing the pumping of the light phase of the separated material. The heavy phase transfer pump 34 is located between the heavy phase storage tank 23 and the hydrophilic membrane filter tank 32, and the input end of the heavy phase transfer pump 34 is connected to the output end of the heavy phase storage tank 23, while the output end of the heavy phase transfer pump 34 is connected to the input end of the hydrophilic membrane filter tank 32, thereby realizing the pumping of the heavy phase of the separated material.

[0031] Furthermore, the filtration module 3 also includes a clean oil phase collection tank 35 and a clean water phase collection tank 36. The input end of the clean oil phase collection tank 35 is connected to the output end of the hydrophobic membrane filter tank 31 to collect the filtered clean oil. The input end of the clean water phase collection tank 36 is connected to the output end of the hydrophilic membrane filter tank 32 to collect the filtered clean water.

[0032] Furthermore, the control module 4 includes a processor 41 and a human-machine interface 42. The processor 41 is electrically connected to the human-machine interface 42, the feed pump 14, the PTC heating sleeve 11, the centrifuge 21, the light phase storage tank 22, the heavy phase storage tank 23, the light phase transfer pump 33, the heavy phase transfer pump 34, the hydrophobic membrane filter tank 31, and the hydrophilic membrane filter tank 32, thereby realizing the intelligent control of the entire separation and filtration device.
