Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a filtration device for the production of hand sanitizer. Background Technology

[0002] As a hygiene product that comes into direct contact with the skin, the production process of hand sanitizer places stringent requirements on filtration accuracy, safety, and production efficiency. Currently, traditional filtration devices generally face two major technical bottlenecks:

[0003] On the one hand, the lack of a layered filtration design leads to incomplete impurity interception. Existing devices mostly use a single filtration layer or a simple combination, which cannot filter contaminants of different particle sizes in disinfectant solutions, such as raw material particles of 5-100μm, colloidal impurities of 0.1-5μm, microorganisms and pyrogens of 0.02-0.2μm. A single filter element has to perform both coarse and fine filtration functions at the same time, which is prone to clogging by large particles, resulting in a sharp drop in filtration flux. In addition, the precision membrane layer is in direct contact with high concentrations of impurities, which accelerates membrane pore blockage and structural damage, ultimately causing the filtrate to exceed the microbial load or lose effective components.

[0004] On the other hand, the non-removable and non-replaceable structure of the filter membrane leads to problems such as high maintenance costs and poor production continuity. Traditional equipment mostly uses fixed membrane modules. When a certain membrane layer fails due to pollution or aging, the entire filter unit needs to be shut down and disassembled. This takes too long and seriously affects the efficiency of large-scale production. At the same time, the non-removable design leads to incomplete cleaning. Residual proteins, surfactants and other pollutants on the membrane surface can easily breed biofilms, creating a risk of secondary pollution. In addition, different formulations of disinfectant solutions have different requirements for the corrosion resistance of membrane materials. The fixed structure cannot flexibly replace the appropriate membrane material, resulting in a shortened membrane life. Moreover, the entire membrane needs to be discarded when it is replaced, resulting in high consumable costs.

[0005] In summary, existing filtration technologies result in low filtration efficiency, difficult maintenance, high costs, and difficulty in meeting the stringent safety and stability requirements of hand sanitizers. Utility Model Content

The worm and the worm gear are meshed together.

[0019] (1) The filtration device for producing hand sanitizer has the following characteristics: after passing through the filter screen, the sanitizer flows in the order of vertical flow under gravity through three layers of filtration membranes: ceramic membrane, fiber membrane, and nanofiltration membrane, which are ultrasonically welded to the membrane support. The ceramic membrane is usually made of inorganic material and mainly filters micron-sized particles, which can clarify the base liquid of the sanitizer containing suspended matter. The fiber membrane mainly filters nano-sized colloids and can finely filter and intercept viruses and pyrogens. The nanofiltration membrane mainly filters small molecule organic matter and can concentrate and recover alcohol and enrich active ingredients. The detachable filtration membrane structure has multiple advantages: it can realize component-level maintenance without disassembling the whole device, shorten downtime, improve production continuity, and reduce consumable costs by replacing individual membrane sheets as needed. It supports flexible replacement of membrane materials and adjustment of precision. Replacement of components can be handled separately to ensure filtration effect.

The scraper fixed at the lower end of the feed port rotates and scrapes off impurities on the surface of the filter screen. The impurities enter the drain port under the scraping of the scraper. When the drain port is full, the cover can be opened for cleaning. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Please see Figure 1-5 This utility model provides a technical solution: a filtration device for producing hand sanitizer, including a shell 1, four adjustable support legs 2 fixedly installed at the bottom of the shell 1, a filter chamber 18 fixedly installed inside the shell 1, a discharge port 4 fixedly installed at the bottom of the shell 1, the discharge port 4 communicating with the filter chamber 18, and a valve 3 fixedly installed on the discharge port 4.

[0033] A feed inlet 7 is rotatably connected to the top of the outer casing 1. The feed inlet 7 is connected to the interior of the filter chamber 18. A worm gear 8 is fixedly installed on the outside of the feed inlet 7. A motor 10 is fixedly installed on the top of the outer casing 1. A worm 9 is fixedly connected to the output shaft of the motor 10. The worm 9 is meshed with the worm gear 8.

[0034] The outer casing 1 has a drain port 11 on its side, and a cover plate 12 is fixedly installed on the drain port 11. The inner side of the outer casing 1 is equipped with a layered and detachable filter assembly.

[0035] The layered filtration assembly includes: membrane support 5, clip 6, scraper 13, filter screen 14, ceramic membrane 15, fiber membrane 16, nanofiltration membrane 17, horizontal guide rail 19, and sealing gasket 20.

[0036] The filter screen 14 is conical and has filter holes;

[0037] The filter screen 14 is fixedly connected above the filter chamber 18, and the scraper 13 is located on the upper surface of the filter screen 14. The scraper 13 is fixedly connected to the lower end of the feed inlet 7.

[0038] When in use, the staff pours the disinfectant solution to be filtered into the inlet 7. The disinfectant solution enters the shell 1 and first passes through the filter screen 14 for pre-filtration, mainly filtering out larger particles of impurities in the disinfectant solution. When it is necessary to clean the impurities attached to the surface of the filter screen 14, the motor 10 starts and drives the worm gear 9 to rotate. The worm wheel 8 meshing with the worm gear 9 starts to rotate, driving the inlet 7 to rotate. Thus, the scraper 13 fixed at the lower end of the inlet 7 rotates and scrapes off the impurities on the surface of the filter screen 14. The impurities enter the drain port 11 under the scraping of the scraper 13. When the drain port 11 is full, the cover plate 12 can be opened for cleaning.

[0039] The horizontal guide rail 19 is fixedly connected to the inside of the outer shell 1, and the three membrane supports 5 are slidably connected to the middle of the filter chamber 18 through three pairs of horizontal guide rails 19 and arranged parallel to each other.

[0040] The clips 6 are fixedly installed on both ends of the outer side of the membrane support 5. The ceramic membrane 15, the fiber membrane 16 and the nanofiltration membrane 17 are ultrasonically welded to the upper, middle and lower membrane supports 5 in sequence.

[0041] The structure and working principle of the buckle 6 are similar to those of existing standard buckle devices and are well known to those skilled in the art, so its internal structure will not be described in detail. The structure and working principle of the ceramic membrane 15, fiber membrane 16 and nanofiltration membrane 17 are all based on the principle of porous media sieving. Their core function is to separate materials according to their size, similar to filters of different precision, which are well known to those skilled in the art, so their internal structure will not be described in detail.

[0042] After passing through filter screen 14, the disinfectant flows in an up-down order under the action of gravity through three layers of filter membranes: ceramic membrane 15, fiber membrane 16 and nanofiltration membrane 17, which are ultrasonically welded onto membrane support 5.

[0043] Ceramic membranes 15 are typically made of inorganic materials and primarily filter micron-sized particles, which can clarify disinfectant base solutions containing suspended solids.

[0044] The fiber membrane 16 primarily filters nano-sized colloids, and can effectively filter and retain viruses and pyrogens.

[0045] Nanofiltration membrane 17 primarily filters small molecule organic matter, can concentrate and recover alcohol and enrich active ingredients, ultimately ensuring the microbial safety and effective ingredient concentration of the product.

[0046] A sealing gasket 20 is fixedly installed at the closure point between the membrane support 5 and the filter chamber 18.

[0047] The sealing gasket 20 ensures the sealing performance of the device and prevents leakage of disinfectant.

[0048] Working principle: During use, the operator pours the disinfectant solution to be filtered into the inlet 7. The disinfectant solution enters the outer shell 1 and first passes through the filter screen 14 for pre-filtration, mainly filtering out larger particles of impurities in the disinfectant solution. When it is necessary to clean the impurities adhering to the surface of the filter screen 14, the motor 10 starts and drives the worm gear 9 to rotate. The worm wheel 8 meshing with the worm gear 9 starts to rotate, driving the inlet 7 to rotate. This causes the scraper 13 fixed at the lower end of the inlet 7 to rotate and scrape off the impurities on the surface of the filter screen 14. The impurities are scraped into the drain port 11 by the scraper 13. When the drain port 11 is full... The cover plate 12 can be opened for cleaning. After passing through the filter screen 14, the disinfectant flows in the order of top to bottom under the action of gravity through the three layers of filter membranes: ceramic membrane 15, fiber membrane 16 and nanofiltration membrane 17, which are ultrasonically welded to the membrane support 5. The ceramic membrane 15 is usually an inorganic material and mainly filters micron-sized particles, which can clarify the disinfectant base liquid containing suspended solids. The fiber membrane 16 mainly filters nano-sized colloids and can finely filter and intercept viruses and pyrogens. The nanofiltration membrane 17 mainly filters small molecule organic matter, which can concentrate and recover alcohol and enrich active ingredients, ultimately ensuring the microbial safety and effective ingredient concentration of the product.

[0049] When installing the filter membrane, the membrane support 5 slides and aligns with the filter chamber 18 via the horizontal guide rail 19. The sealing gasket 20, which is fixedly installed on the membrane support 5, seals the filter chamber 18. The buckle 6 is closed to prevent the membrane support 5 from sliding and causing leakage of disinfectant. When the filter membrane needs to be replaced, the buckle 6 is opened and the membrane support 5 can be slid out for replacement. After the disinfectant has been filtered through three layers of filter membranes, the valve 3 is opened and the disinfectant flows out from the outlet 4 for the next step of processing.

[0050] The detachable filter membrane structure has multiple advantages: it enables component-level maintenance without disassembling the entire unit, shortening downtime and improving production continuity; it also reduces consumable costs by allowing individual membrane sheets to be replaced as needed; it supports flexible replacement of membrane materials and adjustment of precision; replacement components can be handled separately to ensure filtration effect; it facilitates deep internal cleaning and disinfection, meeting the high hygiene standards required for pharmaceutical, food, and other production processes; and the combination of layered filtration and detachable maintenance reduces membrane load, removes contaminants in a timely manner, maintains stable system operating pressure, and extends the overall lifespan of the equipment.

[0051] In summary, the layered filtration membrane structure balances efficiency, cost, quality, and safety in the production of hand sanitizers, and is a key design for achieving refined filtration and sustainable production.

[0052] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
