Description

Technical Field

[0001] This application relates to the field of fragrance processing equipment technology, and in particular to a multi-stage filtration device for fragrance production. Background Technology

[0002] As consumers increasingly demand higher product quality, fragrances, as an important ingredient in various consumer products, are prone to affecting the quality of manufactured products due to their purity.

[0003] In related technologies, although fragrance filtration equipment can initially remove internal impurities, it still has certain limitations in fine filtration, resulting in too many impurities remaining in the fragrance after filtration, thus making the fragrance less pure. Summary of the Invention

[0004] In order to improve the purity of fragrance after filtration, this application provides a multi-stage filtration device for fragrance production.

[0005] The multi-stage filtration device for flavor production provided in this application adopts the following technical solution: A multi-stage filtration device for flavor production includes a filtration assembly. The filtration assembly includes several connecting sleeves that are connected in sequence. Each connecting sleeve contains a filtration component. The filtration components are classified according to their function as a pre-filtration component for filtering larger solid particles, a fine filtration component for filtering fine impurities, an ultrafiltration component for filtering macromolecules with a diameter greater than 0.05 micrometers, and a nanofiltration component for removing salts and other ionic compounds from the solute. A backwashing component, which is connected to the filtration assembly, is provided on one side of the filtration assembly for periodically rinsing the internal filtration components.

[0006] By adopting the above technical solution, the feeding assembly is used to store the pre-filtered fragrance and transport the fragrance stored in the feeding assembly to the filtering assembly. The fragrance in the filtering assembly flows through multiple stages of filtration components, gradually trapping impurities and improving the filtration effect. Furthermore, the filtration level of the transition unit can be flexibly adjusted according to production requirements to better adapt to the market.

[0007] The combined filter element of PP cotton, activated carbon, and glass fiber has excellent adsorption properties, effectively removing fine impurities from fragrances and thus improving their purity. At the same time, this combined filter element has a long service life, reducing the cost and maintenance workload associated with frequent filter replacements.

[0008] Polysulfone semipermeable membranes have selective permeability, which can effectively retain macromolecules with a diameter greater than 0.05 micrometers, thereby further removing impurities from fragrances and improving the purity of fragrances.

[0009] Cellulose acetate semipermeable membranes are thin films with a specific pore structure that enable selective permeation of molecules and ions, further removing salts and other ionic compounds from fragrances, thereby improving the purity of the fragrance.

[0010] The backwashing unit periodically flushes the filter components, effectively removing residues and impurities adhering to their surfaces, thus preventing clogging and extending their lifespan. Furthermore, regular cleaning helps maintain the filtration efficiency of the filter components, ensuring the stability of the fragrance production process and the reliability of product quality.

[0011] Optionally, the filter assembly also includes several splicing pipes that are interference-fitted with the connecting sleeve. The inner wall of the connecting sleeve is provided with a positioning ring, and positioning sealing rings are provided on both sides of the positioning ring. The splicing pipes abut against the positioning sealing rings.

[0012] By adopting the above technical solution, the splicing pipe and the connecting sleeve are tightly connected to prevent liquid flowing into the filter assembly from leaking out.

[0013] Optionally, a filter plate is slidably connected to the connecting sleeve, the filter component is set on the filter plate, and an arc-shaped groove is opened on the inner wall of the positioning ring, and the filter plate is engaged with the arc-shaped groove.

[0014] By adopting the above technical solution, the filter plate on the connecting sleeve can be disassembled, making it convenient for staff to replace the filter components.

[0015] Optionally, a feed hopper is provided on one side of the filter assembly, and a feed valve is provided on the side wall of the feed hopper. The feed valve is connected to one end of an arc-shaped pipe through a pipeline, and the other end of the arc-shaped pipe is connected to the filter assembly.

[0016] By adopting the above technical solution, the liquid in the feed hopper can enter the arc-shaped pipe through the feed valve, and then flow into the filter assembly for filtration through the arc-shaped pipe.

[0017] Optionally, the curved section of the arc-shaped pipe is connected to a transfer hopper, a transfer valve is provided between the arc-shaped pipe and the transfer hopper, and a return pump is connected to the transfer hopper via a pipe. The return pump is connected to the feed hopper via a pipe.

[0018] By adopting the above technical solution, the liquid remaining in the arc-shaped pipe can enter the transfer hopper through the transfer valve, and then be pumped into the feed hopper by the return pump, thereby reducing production waste.

[0019] Optionally, the transfer silo is connected to a recovery silo via a pipeline, and a recovery pump is installed between the transfer silo and the recovery silo to pressurize the liquid inside the transfer silo into the recovery silo.

[0020] By adopting the above technical solution, wastewater in the transfer silo can be pumped into the recycling silo by a recycling pump, making it convenient for staff to collect the wastewater.

[0021] Optionally, the filter assembly is connected to a limiting valve for controlling the outflow of liquid inside the filter assembly, and the limiting valve is connected to a storage silo.

[0022] By adopting the above technical solution, the fragrance flows from the filter component into the storage silo. The flow rate of the fragrance into the storage silo is controlled by the limiting valve to prevent excess fragrance from flowing into the storage silo when the staff cleans it.

[0023] Optionally, the backwashing assembly includes a liquid storage tank, a liquid outlet valve is provided on the side wall of the liquid storage tank, the liquid outlet valve is connected to the filter assembly, and a nozzle is provided at one end of the liquid outlet valve inside the filter assembly.

[0024] By adopting the above technical solution, the liquid storage tank is used to store cleaning liquid and is connected to the filter assembly through a pipeline, allowing the cleaning liquid to flow into the filter assembly for periodic rinsing. This helps remove residues adhering to the filter assembly, thereby effectively improving the cleanliness and service life of the filter assembly and ensuring the stability of the filtration effect.

[0025] In addition, the nozzle can evenly spray the cleaning liquid in the storage tank onto the filter components, ensuring that the cleaning liquid effectively covers the surface of the filter components, thereby improving the cleaning effect and extending the service life of the filter components.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Fragrances are filtered through multiple stages to remove impurities from the liquid, which helps to improve the purity of the fragrance after filtration and thus improve the quality of the produced products; 2. The backwashing unit regularly cleans the inside of the filter assembly, thereby extending the service life of each stage of the filter components, reducing maintenance frequency, and saving costs; 3. The filter plate increases the flexibility of the filter components, allowing for replacement of filter components according to different production requirements, thus providing a wide range of adaptability.

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0030] A multi-stage filtration device for flavor production, as described in the reference. Figure 1 It includes a feeding assembly 1, a filtering assembly 2, and a storage assembly 3. The feeding assembly 1 is used to feed liquid into the filtering device; the filtering assembly 2 includes several filtering components 205 that filter the fed liquid in stages; and the storage assembly 3 is used to store the liquid after it has been filtered by the filtering assembly 2 and removed impurities.

[0031] The feeding assembly 1 includes a feeding bin 101 for storing unfiltered raw liquid. A feeding valve 102, a feeding pump 103, and an arc-shaped pipe 5 are sequentially fixedly connected to the side wall of the feeding bin 101. The end of the arc-shaped pipe 5 furthest from the feeding pump 103 is fixedly connected to the filter assembly 2. The feeding valve 102 controls the outflow of raw liquid from the feeding bin 101 and its entry into the feeding pump 103. The feeding pump 103 pressurizes the raw liquid through the arc-shaped pipe 5 into the filter assembly 2. The height of the connection between the feeding pump 103 and the arc-shaped pipe 5 is higher than the connection between the filter assembly 2 and the storage assembly 3, resulting in a higher hydraulic pressure at the connection between the feeding pump 103 and the arc-shaped pipe 5 than at the connection between the filter assembly 2 and the storage assembly 3.

[0032] refer to Figure 1 , Figure 2 The filter assembly 2 includes multiple connecting sleeves 201, with a splicing pipe 202 positioned between adjacent connecting sleeves 201. Both ends of the splicing pipe 202 are inserted into the corresponding adjacent connecting sleeves 201 and are press-fitted with the corresponding connecting sleeves 201. The connecting sleeve 201 closest to the arc-shaped tube 5 is also press-fitted with the end of the arc-shaped tube 5. In this embodiment, four connecting sleeves 201 are specifically provided; in other embodiments, a different number may be used.

[0033] refer to Figure 2 , Figure 3 A positioning ring 203 is fixedly connected to the inner wall of the connecting sleeve 201, and the thickness of the positioning ring 203 corresponds to the thickness of the splicing pipe 202. After the splicing pipe 202 is installed in place, the end of the splicing pipe 202 abuts against the positioning ring 203, so that the inner wall of the positioning ring 203 and the inner wall of the splicing pipe 202 transition smoothly.

[0034] A sealing groove 6 with an arched cross-section is provided on the side wall of the connecting sleeve 201. The positioning ring 203 has an arc-shaped groove 7 that communicates with the sealing groove 6, and sealing rings are fixedly connected to the two opposing inner walls of the arc-shaped groove 7.

[0035] A filter plate 204 is slidably connected within the sealing groove 6. The filter plate 204 includes a sealing plate and a snap-fit ​​plate. After the filter plate 204 is installed in place, the snap-fit ​​plate extends into the arc-shaped snap-fit ​​groove 7 and abuts against the sealing ring, while the sealing plate extends into the sealing groove 6 and abuts against the inner wall of the sealing groove 6.

[0036] A filter element 205 is provided in the middle of the snap-fit ​​plate, and the snap-fit ​​plate is fixedly connected to the filter element 205 by stamping and bending. The filter elements 205 in the multiple connecting sleeves 201 perform multi-stage filtration in the flow direction of liquid filtration. The four filter elements 205 in this application are a pre-filtration element, a fine filtration element, an ultrafiltration element, and a nanofiltration element.

[0037] The pre-filtration unit is made of stainless steel mesh and is used to filter larger solid particles.

[0038] The fine filtration unit is a filter cartridge made of a combination of PP cotton, activated carbon, and glass fiber, used to further remove finer impurities.

[0039] The ultrafiltration unit is a semi-permeable membrane made of polysulfone, which relies on the selective permeability of the semi-permeable membrane to retain macromolecules with a diameter greater than 0.1 micrometers.

[0040] The nanofiltration unit is a semi-permeable membrane made of cellulose acetate. Relying on the selective permeability of the semi-permeable membrane, it can further remove salts and other ionic compounds from the solute.

[0041] refer to Figure 2 Two symmetrically arranged connecting plates 8 are fixedly connected to the connecting sleeve 201, with the two connecting plates 8 located on opposite inner walls of the sealing groove 6. Each end of the sealing plate is fixedly connected to a fixing plate 9 corresponding to the position of the two connecting plates 8. After the filter plate 204 is installed in place, the fixing plate 9 abuts against the corresponding connecting plate 8, and both the fixing plate 9 and the connecting plate 8 have through holes and can be fastened with bolts.

[0042] refer to Figure 1 , Figure 2A connecting sleeve 201, equipped with a nanofiltration unit, is connected to a backwashing assembly 4 via a first three-way pipe 10. The backwashing assembly 4 includes a storage tank 401 positioned above the filter assembly 2, containing hydrosol for rinsing the filter assembly 205. An outlet valve 402 is also provided between the storage tank 401 and the first three-way pipe 10, controlling the opening and closing relationship between them. A nozzle 403 is fixedly connected to the end of the outlet valve 402 facing away from the storage tank 401, and the nozzle 403 is located inside the first three-way pipe 10.

[0043] refer to Figure 1 The storage assembly 3 includes a storage bin 301 located on one side of the first three-way pipe 10, and the storage bin 301 and the first three-way pipe 10 are connected by a limiting valve 302.

[0044] A transfer chamber 12 is provided on the side of the arc-shaped pipe 5 away from the feeding assembly 1 and the backflushing assembly 4. The transfer chamber 101 is located at the lowest point of the U-shaped bend of the arc-shaped pipe 5. The arc-shaped pipe 5 and the transfer chamber 12 are connected by a transfer valve 11. After the transfer valve 11 is opened, the liquid in the arc-shaped pipe 5 flows into the transfer chamber 12.

[0045] The lower end face of the transfer hopper 12 is fixedly connected to a discharge valve 13 for controlling the outflow of liquid in the transfer hopper 12. One end of the discharge valve 13 is fixedly connected to a second three-way pipe 14 and communicates with the pipe opening at the side wall of the second three-way pipe 14.

[0046] A reflux valve 15 is fixedly connected to the side of the second three-way pipe 14 near the feed hopper 101. One end of the reflux valve 15 is connected to a reflux pump 16 via a pipe to pressurize the liquid in the transfer hopper 12 into the feed hopper 101.

[0047] The other end of the return pump 16 is connected to the return valve 17 via a pipe. One end of the return valve 17 is fixedly connected to the outer shell of the feed hopper 101 and communicates with the inside of the feed hopper 101, so that excess fragrance in the arc-shaped pipe 5 flows back into the feed hopper 101.

[0048] A recovery valve 18 is fixedly connected to the other end of the second three-way pipe 14 away from the return valve 15. One end of the recovery valve 18 is connected to a recovery pump 19 through a pipe. One end of the recovery pump 19 is connected to a recovery bin 20 through a pipe. The recovery pump 19 pumps the waste water in the transfer bin 12 into the recovery bin 20 for storage, so that the staff can handle it centrally.

[0049] The implementation principle of this application embodiment is as follows: the feed is turned on, allowing the fragrance in the feed hopper 101 to flow into the arc-shaped tube 5 and deposit there. As the fragrance continues to flow into the feed hopper 101, the fragrance liquid in the arc-shaped tube 5 gradually passes through the pre-filtration unit, fine filtration unit, ultrafiltration unit, and nanofiltration unit, and then flows into the storage hopper 301. During this process, some impurities in the fragrance are deposited at the bottom of the arc-shaped tube 5 under the action of gravity.

[0050] During regular cleaning, after closing the feed valve 102 and the limiting valve 302, open the transfer valve 11 to introduce the remaining fragrance in the pipeline into the transfer hopper 12. Then, open the reflux valve 15 and the return valve 17 and start the reflux pump 16 to press the remaining fragrance in the transfer hopper 12 into the feed hopper 101.

[0051] After all the remaining fragrance has entered the feed hopper 101, close the reflux valve 15, return valve 17, and reflux pump 16. Open the outlet valve 402, and the hydrosol flows downward from the storage hopper 401 under the influence of gravity and is sprayed out from the nozzle 403, causing the hydrosol to be sprayed onto the filter element 205. When there is too much hydrosol in the pipeline, open the recovery valve 18 and recovery pump 19, and the hydrosol in the pipeline is forced into the recovery hopper 20.

[0052] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
