Description

Technical Field

[0001] This invention relates to the field of filtration and adsorption, and more specifically, to a graphene filtration and adsorption device for edible liquids and its application. Background Technology

[0002] In today's society, various types of purified water, mineral water, beverages, cooking oil, liquid condiments, alcoholic beverages, and other types of drinks are generally packaged in containers made of polymer materials, such as plastics (PP and PE). The production process of these polymer plastic containers involves heating the polymer plastic raw materials to a molten state, then blow molding and cooling them at high temperatures to obtain the container. However, in this series of production steps, some plastic residue often inevitably remains inside the plastic container. More worryingly, when these polymer material containers are placed in high-temperature environments or exposed to strong sunlight for extended periods, the polymer materials themselves may separate. The separation process of polymer materials such as plastics releases various chemical substances, including bisphenol A and phthalates; the separation process of polymer materials such as glass releases free silica and heavy metals such as lead, nickel, and arsenic. These substances have been proven to pose potential health hazards. Long-term consumption of beverages containing these harmful chemicals may adversely affect the endocrine and reproductive systems, thus posing a serious threat to overall health.

[0003] In the current polymer packaging system, we face a serious problem: the lack of an effective mechanism for handling potentially harmful substances. Although some research is striving to develop new environmentally friendly polymer materials, limitations in cost and technology make it difficult for these materials to be widely applied to the market in the short term. Meanwhile, the market is already flooded with a large number of polymer packaging products.

[0004] Therefore, how to take measures during use to reduce the potential threats to human health from the separation of polymer materials has become an urgent problem to be solved. There is a pressing need to provide a portable, reusable filtration device to remove harmful substances from containers. Summary of the Invention

[0005] The purpose of this invention is to provide a graphene filtration and adsorption device for edible liquids. This device can effectively filter and separate harmful substances generated during the use of polymer material containers holding edible liquids, ensuring the safety and health of beverages. It also features adaptability, portability, and reusability, making it convenient for consumers to use, reducing usage costs, and minimizing resource waste.

[0006] Another objective of this invention is to provide a graphene filtration and adsorption device for edible liquids and its application. This adsorption and filtration device can be installed as an accessory at the mouth of a container to provide timely filtration and effectively remove harmful substances from the liquid.

[0007] The technical problem solved by this invention is achieved by the following technical solution.

[0012] In some embodiments of the present invention, the adsorption structure includes a pre-filtration layer, an adsorption layer, and a fine filtration layer arranged sequentially according to the flow direction of the liquid.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply. Reagents or instruments whose manufacturers are not specified are all conventional products that can be purchased commercially.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to specific embodiments.

[0032] This invention provides a graphene filtration and adsorption device for edible liquids, comprising:

[0033] The device comprises a tubular main body 100 and an adsorption structure 200. The tubular main body has a channel, an inlet end 110, and an outlet end 120. The inlet end 110 and the outlet end 120 are located at opposite ends of the channel, and the inlet end 110 is detachably connected to the mouth of a container. The adsorption structure 200 is disposed within the channel. When using the device, liquid flows into the channel from the inlet end 110, passes through the adsorption structure 200, and then flows out from the outlet end 120. The adsorption structure 200 adsorbs harmful impurities in the liquid.

[0034] In some embodiments of the present invention, the detachable connection is one or more of the following: interference fit, threaded connection, and snap-fit ​​connection. It should be noted that an interference fit can be understood as inserting the liquid inlet end of the tubular body into the bottle neck of a container, with the connection in an interference fit state. The slight elastic deformation of the plastic bottle neck allows for the insertion or removal of the tubular body. Similarly, the bottle neck can also be inserted into the channel of the tubular body to achieve an interference fit detachable connection.

[0035] A threaded connection is used, where the inner wall of the inlet end of the channel has internal or external threads, which can mate with the external or internal threads of the bottle opening to achieve a detachable connection. Preferably, the connection between the tubular body and the solution bottle opening is a threaded connection. In actual production, a universal internal thread can be used, compatible with most bottle openings on the market (such as mainstream brand mineral water bottles and beverage bottles), thus broadening its applicability. By rotating the thread, the adsorption device can be securely installed on the container holding the edible liquid, ensuring a tight seal and preventing leakage. Additionally, an anti-misinstallation marking can be provided at the connection structure to ensure that the device can be correctly installed on containers of different sizes, improving ease of use and versatility.

[0036] The snap-fit ​​connection is a type of connection where a snap-fit ​​is installed on the liquid inlet end of the tubular body. By utilizing the slight elastic deformation of the snap-fit, it can be snapped onto the protruding edge of the container mouth to achieve a detachable connection.

[0037] For example, in outdoor emergency scenarios, manual pressurization devices are often required to filter liquids, which places high demands on the connection method, compatibility, and sealing of the filter adsorption device and the bottle. In some embodiments of the present invention, interference fit, threaded fit, and snap-fit ​​fit can meet the needs of such scenarios. Among them, snap-fit ​​fit and threaded fit have the characteristic of being used under pressure, and are more adaptable to the pressure environment of manual pressurization devices.

[0038] Preferably, in order to meet the requirements of pressurized filtration (such as manually squeezing the plastic bottle to allow the water in the bottle to pass through the filtration adsorption device quickly), a transverse partition structure can be provided in the channel of the tubular body 100 near the liquid outlet end to prevent the adsorption structure 200 from separating from the tubular body 100 under the action of water pressure.

[0039] It should be noted that the manufacturing process of the tubular body 100 of the filtration and adsorption device provided in this invention is as follows: the device is welded together from two identical tubular structures, wherein a transverse diaphragm structure 160 is provided inside the tubular body 100. This transverse diaphragm structure 160 serves as both a filter layer limiter and a pressure-resistant enhancement. Specifically, the adsorption structure 200 is first installed inside one tubular body 100, and then the two identical tubular bodies 100 are welded together. The specific position of the transverse diaphragm structure 160 within the tubular body 100 can be precisely determined based on the thickness of the adsorption structure 200 by reserving appropriate manufacturing welding allowance and setting a certain gap. The advantages of this process are: a simple manufacturing process requiring only one welding operation, and the finished product possessing a certain pressure resistance.

[0040] More preferably, it also includes a dust cover for sealing the liquid outlet end, the dust cover being connected to the tubular body, the connection being one or more of snap-fit ​​connection, hinge connection, threaded connection or interference fit.

[0041] Regarding the detachable connection method of the dust cover, it should be noted that the dust cover can be a separate connection from the tubular body, such as a snap-fit ​​connection, threaded connection, or interference fit, or it can be an integral connection, such as a hinge. Preferably, the dust cover can be the original bottle cap, that is, an external thread is provided at the liquid outlet end of the tubular body. This external thread can engage with the internal thread of the original bottle cap, allowing the original bottle cap to be installed at the liquid outlet end of the tubular body, thereby sealing the liquid outlet end of the tubular body.

[0042] In some embodiments of the present invention, a sealing ring is further included. The sealing ring is disposed within the channel and is used to seal the connection between the tubular body and the container mouth. The sealing ring, made of food-grade rubber, is disposed at the connection between the tubular body and the container holding the edible liquid. This sealing ring has good elasticity and sealing performance, enabling it to form a tight seal when the device is connected to the container holding the edible liquid. This prevents external air, dust, and bacteria from entering the container, and also avoids leakage of the edible liquid during transportation and storage, ensuring the quality and safety of the edible liquid.

[0043] In some embodiments of the present invention, the adsorption structure includes a pre-filtration layer, an adsorption layer, and a fine filtration layer arranged sequentially according to the flow direction of the liquid.

[0044] In some embodiments of the present invention, the pre-filter layer is made of graphene composite polyfiber with a pore size of 15-200 μm. The graphene composite polyfiber can be a composite material of graphene and polypropylene fiber, or a composite material of graphene and polyester fiber; its preparation method involves processing graphene and polypropylene fiber or polyester fiber, etc., through processes such as carding, web laying, and hot pressing to form a fiber felt with a certain thickness and porosity, which serves as the pre-filter layer. The pore size and thickness of the fiber felt are controlled to effectively intercept larger particle impurities.

[0045] In some embodiments of the present invention, the adsorption layer is made of graphene composite activated carbon and nano-titanium dioxide. The preparation method is as follows: graphene and activated carbon are pulverized into suitable particle sizes, thoroughly mixed with catalytic materials such as titanium dioxide nanoparticles, and an appropriate amount of binder, such as polyvinyl alcohol (PVA), is added. The mixture is then formed into an adsorption separation layer with a certain shape and thickness by pressing or coating. During the preparation process, it is ensured that the activated carbon and catalytic materials are uniformly distributed to guarantee the adsorption and separation effect.

[0046] In some embodiments of the present invention, the fine filtration layer is made of an ultra-microporous filtration membrane with a pore size of 20-200 μm. The preparation method is as follows: a polyvinylidene fluoride (PVDF) ultra-microporous membrane is prepared using a phase inversion method or a stretching method, controlling parameters such as pore size, porosity, and thickness to meet the requirements of fine filtration. The prepared ultra-microporous membrane is then cut to a suitable size for later use.

[0047] The assembly method is as follows: the pre-filtration layer, adsorption separation layer, and fine filtration layer are stacked sequentially and fixed together by ultrasonic welding or hot pressing to form a complete layered adsorption structure. The filtration separation layer is installed in a pre-designed position inside the main body of the device, ensuring a tight fit between the filtration separation layer and the main body to prevent leakage of edible liquids during the filtration separation process.

[0048] It should be noted that two annular protrusions can be provided inside the tubular body, and the edge of the adsorption structure can be engaged between the two annular protrusions to achieve a detachable connection between the adsorption structure and the tubular body; alternatively, an annular groove can be provided on the inner wall of the tubular body, and the edge of the adsorption structure can be engaged in the annular groove to achieve a detachable connection between the adsorption structure and the tubular body; in other embodiments of the present invention, the adsorption structure can also be fixedly connected to the tubular body, that is, the edge of the adsorption structure is fixed to the inner wall of the tubular body by glue or other means.

[0049] On the other hand, embodiments of the present invention provide an application of a graphene filtration and adsorption device for edible liquids, wherein the adsorption device is installed at the mouth of a container bottle for filtering and adsorbing impurities in the liquid inside the container bottle.

[0050] The method of using this adsorption device is as follows:

[0051] Installing the adsorption device: Taking a threaded connection as an example, align the adsorption device of this invention with the container opening, and rotate the device clockwise according to the direction indicated by the anti-misinstallation mark, so that the internal thread of the tubular body is tightly screwed into the external thread of the container opening, until the device is securely installed on the polymer container. At this time, the rubber sealing ring of the sealing structure will form a tight seal between the device and the polymer container opening, preventing leakage of edible liquid and the entry of external impurities.

[0052] To use the edible liquid in the bottle: Open the dust cap at the top of the device. The liquid inside the bottle flows out through the inlet, adsorption structure, and outlet in sequence, and is then ready for use. During the process of the edible liquid flowing from the container through the device, it first passes through a pre-filtration layer to intercept larger plastic residues and impurities. Then it enters the adsorption layer, where harmful chemicals are adsorbed by activated carbon and separated into harmless substances under the action of nano-catalytic materials. Finally, it passes through a fine filtration layer to further remove residual microparticles and incompletely separated harmful chemical molecules, ensuring that the edible liquid flowing out is safe and healthy.

[0053] Reuse: After the liquid in the container is used up, rotate the device counterclockwise to detach it from the polymer container. Rinse the adsorption structure and tubular body inside the device with clean water to remove residual beverage and impurities. For stubborn stains, gently scrub with a soft-bristled brush, but be careful not to damage the filter separation layer. After cleaning, allow the device to air dry before reinstalling it on other containers for reuse.

[0054] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0055] Example 1

[0056] As shown in the attached figure, this embodiment provides a graphene filtration and adsorption device for edible liquids, comprising: a tubular main body 100 and an adsorption structure 200;

[0057] The tubular body 100 has a channel, an inlet end 110, and an outlet end 120. The inlet end 110 and the outlet end 120 are located at opposite ends of the channel. The inlet end 110 is detachably connected to the mouth of a container. The adsorption structure 200 is disposed within the channel: an annular groove 150 is provided on the inner wall of the tubular body 100, and the edge of the adsorption structure 200 is engaged within the annular groove 150. When using the device, liquid flows into the channel from the inlet end 110, passes through the adsorption structure 200, and then flows out from the outlet end 120. The adsorption structure 200 can adsorb harmful impurities in the liquid.

[0058] In this embodiment, the detachable connection is a threaded connection. An internal thread 130 is provided on the inner wall of the liquid inlet end 110 of the channel, and this internal thread 130 can engage with the external thread of the bottle mouth to achieve a detachable connection. By rotating the thread, the adsorption device can be securely installed on the container holding the edible liquid, ensuring a tight seal and preventing leakage. Simultaneously, an anti-misinstallation marking can be provided at the connection structure to ensure that the device can be correctly installed on containers of different sizes holding edible liquids, improving ease of use and versatility.

[0059] In this embodiment, the adsorption structure 200 includes a pre-filtration layer 210, an adsorption layer 220, and a fine filtration layer 230 arranged sequentially according to the flow direction of the liquid.

[0060] The pre-filter layer 210 is made of graphene composite polyfiber with a pore size of 15-200 μm. Its preparation method is as follows: using existing processes, graphene and polypropylene fibers are combed, laid, and hot-pressed to form a fiber felt with a certain thickness and porosity, which serves as the pre-filter layer 210.

[0061] The adsorption layer 220 is a composite material of graphene, activated carbon, and nano-titanium dioxide. Its preparation method is as follows: using existing processes, graphene and activated carbon are pulverized into suitable particle sizes, then thoroughly mixed with titanium dioxide nanoparticles, and an appropriate amount of polyvinyl alcohol (PVA) binder is added. The mixture is then pressed to form an adsorption layer 220 with a specific shape and thickness.

[0062] The fine filtration layer 230 is made of an ultra-microporous filtration membrane with a pore size of 20-200 μm. It is prepared by using a phase inversion method or a stretching method to prepare a polyvinylidene fluoride (PVDF) ultra-microporous membrane, controlling parameters such as pore size, porosity, and thickness to meet the requirements of fine filtration. The prepared ultra-microporous membrane is then cut to a suitable size for later use. Alternatively, a polyvinylidene fluoride (PVDF) ultra-microporous membrane can be purchased directly from the market.

[0063] The manufacturing process of the adsorption device in this embodiment is as follows: Food-grade environmentally friendly polymer plastic materials, such as polyethylene terephthalate (PET) or polypropylene (PP), are selected and processed into a tubular body 100 using injection molding. During the injection molding process, parameters such as mold temperature, pressure, and injection time are precisely controlled to ensure the dimensional accuracy and surface quality of the device body. An outlet and a dust cover 300 are pre-installed at the top of the device body, and an internal thread 130 is machined on the inner wall of the tubular body 100 to match the opening of a container holding edible liquids.

[0064] Taking a mineral water bottle as an example, when using the adsorption device of this embodiment, first open the cap of the mineral water bottle, then align the tubular body 100 with the container opening, and rotate the device clockwise according to the direction indicated by the anti-misinstallation mark (for example, an arrow indicating the direction of rotation is provided on the tubular body), so that the internal thread 130 of the inner wall of the tubular body 100 is tightly screwed into the external thread of the container opening until the device is firmly installed on the polymer container device; then tilt the bottle and pour out the liquid inside the bottle.

[0065] The adsorption device of this embodiment can be reused. After the liquid in the container bottle is poured out, the adsorption device is removed from the bottle mouth, and then the adsorption structure 200 is removed (the material of the adsorption structure 200 is relatively soft, and it can be removed by utilizing its elastic deformation). After cleaning the residual liquid, impurities, etc. on the tubular body 100 and the adsorption structure 200, it can be reused.

[0066] Example 2

[0067] Based on Embodiment 1, a dust cover 300 for sealing the liquid outlet 120 of the tubular body 100 can also be provided, and the dust cover 300 is connected to the tubular body 100. In this embodiment, the dust cover 300 is independent and is connected to the external thread 140 of the liquid outlet 120 of the tubular body 100 via an internal thread. In other embodiments of the present invention, the dust cover 300 is connected by a hinge, that is, the dust cover 300 is a flip-top type as in the prior art. Its connection method can also be one or more of threaded connection, snap-fit ​​connection, or interference fit.

[0068] To further improve the sealing performance at the connection between the adsorption device and the container, some embodiments of the present invention also include a sealing ring. The sealing ring is disposed within the channel and is used to seal the connection between the tubular body and the container mouth. The sealing ring, made of food-grade rubber, is located at the connection between the tubular body and the container holding the edible liquid. This sealing ring possesses good elasticity and sealing performance, enabling it to form a tight seal when the device is connected to the container holding the edible liquid. This prevents external air, dust, and bacteria from entering the container, and also avoids leakage of the edible liquid during transportation and storage, ensuring the quality and safety of the edible liquid.

[0069] Example 3

[0070] Based on Example 2, a transverse diaphragm structure 160 is provided within the channel of the tubular body 100 near the liquid outlet end to prevent the adsorption structure 200 from separating from the tubular body 100 under water pressure. (See attached...) Figure 6-7 As shown.

[0071] The manufacturing process of the tubular body 100 is as follows: The device is welded together from two identical tubular bodies 100. One of the tubular bodies 100 has a transverse diaphragm structure 160 inside, which serves as both a filter layer limiter and a pressure-enhancing element. Specifically, the adsorption structure 200 is first installed inside the tubular structure, and then the two identical tubular structures are welded together. The exact position of the transverse diaphragm structure within the tubular body 100 can be precisely determined based on the thickness of the filter layer by allowing appropriate manufacturing and welding allowances and setting a certain gap. The advantages of this process are: simple manufacturing process, requiring only one welding operation, and the finished product possesses a certain pressure resistance.
