The transmission member is connected to the extraction plate.

[0015] The extraction device includes a driving component, which is located at opposite ends of the housing in the vertical direction. The driving shaft of the driving component is connected to opposite ends of the transmission component to drive the extraction assembly to move relative to the housing.

[0016] In an exemplary embodiment of this disclosure, the housing includes an extraction section and two settling sections, the two settling sections being located at opposite ends of the extraction section in the vertical direction, and the settling sections communicating with the extraction section; wherein, the first liquid inlet is located at the top of the extraction section, the second liquid inlet is located at the bottom of the extraction section, and the extraction plate reciprocates vertically within the extraction section.

[0017] In one exemplary embodiment of this disclosure, a plurality of settlement plates are provided within the settlement section, inclined relative to the lateral direction, and the plurality of settlement plates are arranged vertically at intervals; the settlement plates are provided with a plurality of spaced-apart through holes, and the settlement plates include a plurality of intersecting and continuously arranged second concave portions and second convex portions, the second concave portions protruding towards the top surface of the settlement plate, and the second convex portions protruding towards the bottom surface of the settlement plate; and / or,

[0018] The side wall of the housing is provided with a first outlet and a second outlet communicating with the receiving space. The first outlet is located at the upper part of the housing and is located on opposite sides of the housing in the lateral direction with the first liquid inlet. The first outlet is used to discharge the wine product. The second outlet is located at the lower part of the housing and is located on opposite sides of the housing in the lateral direction with the second liquid inlet.

[0022] The technical solutions provided in this disclosure have at least the following advantages:

[0023] In this embodiment, an extraction assembly is provided inside the housing. The extraction plate in the extraction assembly can reciprocate vertically and / or rotate circumferentially relative to the housing.

This promotes mass transfer between the two phases, thereby improving the product acquisition efficiency while purifying the alcoholic beverage.

[0024] Meanwhile, in this embodiment, by setting multiple through holes between the inner and outer walls of the sieve, the liquid will tear and flow along the through holes during the vertical reciprocating operation of the extraction plate, and the large molecules in the liquid will be divided into small molecules, which can make the transfer between the two liquid phases more complete and improve the separation efficiency of the entire extraction process of the extraction equipment.

[0044] Vodka, derived from the Russian word "voda" meaning "water," is a more evocative term highlighting its purity and strength. Its history dates back centuries, closely linked to the bountiful grain harvests and love of alcohol in Eastern Europe. The earliest vodka was likely brewed by medieval Eastern European monks using grains such as rye, barley, and wheat, employing fermentation and distillation techniques to create this high-proof spirit. Initially used primarily as medicine and a disinfectant, vodka gradually became a staple alcoholic beverage in Eastern Europe, even becoming the national drink of some countries.

[0045] The production process of vodka involves the following steps: First, grains or potatoes are ground into mash, and then alcohol is extracted through fermentation and distillation. Next, a mixture of edible alcohol and water is used to create an alcohol-water mixture, which undergoes a first filtration, activated charcoal treatment, and a second filtration. Finally, the mixture is adjusted to the specified alcohol concentration before bottling and sale. Vodka typically does not require aging and is characterized by being colorless and odorless, with an alcohol concentration generally between 40% and 60%.

[0046] The process of making vodka involves distilling a base spirit with an alcohol content of ≥96%, which is then blended to obtain a spirit with a content of 40% to 50% for direct drinking.

[0047] Vodka is popular worldwide, produced not only in Eastern European countries like Russia and Poland, but also in countries such as the United States, Germany, the United Kingdom, and Japan, where high-quality vodka is produced. Vodka is often used as a base spirit in cocktails, and is loved for its high alcohol content, flavor, and versatility. Vodka consumption increased dramatically after World War II and it has now become a global spirit.

[0048] The distillation stage is crucial in the entire vodka production process, and currently, pressure swing distillation is still the primary method used for vodka distillation and purification both domestically and internationally. Because vodka has a highly complex composition, sometimes containing thousands of components, the biggest challenge lies in breaking the azeotropic environment during purification to increase the alcohol content to ≥96.4%.

[0049] To solve the above technical problems, such as Figure 1 As shown, this disclosure provides an extraction device 101, including a housing 1 and an extraction assembly.

[0050] Specifically, in this embodiment of the present disclosure, the shell 1 extends vertically along the Y direction and forms a containment space inside, which can contain two immiscible liquid phases.

[0051] like Figures 1 to 3 As shown, the extraction assembly includes an extraction plate 21 disposed in the accommodating space. The extraction plate 21 has a plurality of through sieve holes 211. The axial direction of the sieve holes 211 is at an angle to the horizontal plane, and a plurality of through holes 212 are provided between the inner sidewall and the outer sidewall of the sieve holes 211.

[0052] It should be noted that the aforementioned horizontal plane is perpendicular to the vertical Y direction.

[0053] Define the angle between the axial direction of sieve hole 211 and the horizontal plane as θ, and the value of θ can be in the range of 0 < θ < 180°.

[0054] For example, the value of θ can be 15°, 30°, 45°, 60°, 75°, 90°, 105°, 120°, 135°, 150°, 165°, etc., so that when the extraction plate 21 moves back and forth along the vertical Y direction, the two liquid phases in the containment space can flow through the sieve holes 211 to the vertical top or bottom of the sieve plate to achieve mass transfer between the two liquid phases.

[0055] It should also be noted that the through hole 212 in this embodiment can extend along the axial direction of the sieve hole 211 and penetrate the extraction plate 21, but is not limited thereto. The extension direction of the through hole 212 can also form an angle with the axial direction of the sieve hole 211, and the extension direction of the through hole 212 is not parallel to the horizontal plane.

[0056] In this embodiment of the present disclosure, the extraction plate 21 is made to reciprocate in the vertical Y direction and / or rotate in the circumferential direction relative to the housing 1, so as to continuously update the phase interface by the extraction plate 21, strengthen the contact between the two phases, and enable the solute to be transferred from one phase to another more effectively, thereby promoting mass transfer between the two phases and improving the product acquisition efficiency.

[0057] It should be noted that the extraction plate 21 in this embodiment can adjust its operating parameters according to different systems and process requirements. For example, the amplitude and frequency of the extraction plate 21 in the housing 1 can be adjusted according to the flow rate and ratio of the two liquid phases, so that the extraction device 101 can adapt to different processing flow rates and improve the extraction efficiency and operational flexibility of the extraction device 101.

[0058] The extraction device 101 in this embodiment has a high throughput and can process easily emulsified substances containing solids. The extraction device 101 has a simple structure, which allows it to be scaled up or down according to the liquid flow rate in the containment space.

[0059] In some embodiments, the two liquid phases in the containment space can be the original liquid and water. By causing the extraction plate 21 in the extraction device 101 to reciprocate in the vertical Y direction and / or rotate in the circumferential direction relative to the housing 1, the two liquid phases in the containment space can be stirred and dispersed, thereby promoting mass transfer between the two liquid phases, increasing the alcohol content of the wine product, and obtaining the wine product.

[0060] However, it is not limited to this. The extraction device 101 in the embodiments of this disclosure can also be applied to fields such as pharmaceuticals, petrochemicals, hydrometallurgy and wastewater treatment.

[0061] For example, the extraction device 101 in the embodiments of this disclosure can be used in the ammonia dephenolization process of gas plants and coking plants, or in chemical plants to recover benzene and phenol from wastewater and in pharmaceutical plants to recover aminopyridine.

[0062] In some embodiments, the width of the through hole 212 decreases in the direction away from the center of the sieve hole 211.

[0063] For example, such as Figure 3 As shown, the cross-section of the through hole 212 in this embodiment can be triangular, and the width of the through hole 212 decreases in the direction away from the center of the sieve hole 211. As a result, during the reciprocating motion of the extraction plate 21 along the vertical Y direction, the liquid will tear and flow with the special shape of the through hole 212, and the large molecules in the liquid will be divided into small molecules. This will allow for more complete transfer between the two liquid phases and improve the separation efficiency of the entire extraction process of the extraction equipment 101.

[0064] However, it is not limited to this. Other shapes besides triangles can satisfy the following: the width of the through hole 212 decreases in the direction away from the center of the sieve hole 211 so as to correspond to the tearing flow of the liquid when the extraction plate 21 reciprocates along the vertical Y direction. All of these can be used as the shape of the cross section of the through hole 212 in the embodiments of this disclosure.

[0065] In some embodiments, the plurality of through holes 212 between the inner and outer sidewalls of the sieve hole 211 can be evenly arranged.

[0066] For example, multiple through holes 212 between the inner and outer walls of the sieve 211 can be arranged continuously to increase the number of through holes 212 between the inner and outer walls of the sieve 211, thereby allowing the liquid to be torn and flow as much as possible. This not only enables sufficient mass transfer between the two liquid phases but also accelerates the mass transfer rate between the two liquid phases, thereby improving the separation efficiency of the entire extraction process of the extraction equipment 101.

[0067] However, it is not limited to this. Multiple through holes 212 between the inner and outer walls of the sieve hole 211 can also be evenly spaced to improve the uniformity of the liquid tearing flow.

[0068] like Figures 1 to 2 As shown, in some embodiments, the extraction assembly may include a plurality of extraction plates 21 arranged uniformly and at intervals along the vertical Y direction, and each extraction plate 21 is provided with a plurality of through sieve holes 211.

[0069] This embodiment of the invention improves the separation efficiency of the extraction process by incorporating multiple extraction plates 21 in the extraction assembly, thereby increasing the mass transfer interface between the two liquid phases while simultaneously agitating them. Furthermore, this embodiment enhances the uniformity of the agitation effect of the extraction plates 21 on the two liquid phases by arranging them at uniform intervals along the vertical Y direction.

[0070] In some embodiments, the sieve plate in the extraction assembly may extend along the transverse X direction. However, it is not limited to this; the extension direction of the sieve plate in the extraction assembly may also form an angle with the transverse X direction, and the extension direction of the sieve plate may not be parallel to the vertical Y direction.

[0071] like Figure 4 As shown, in some embodiments, the extraction plate 21 may include a plurality of intersecting and continuously arranged first recesses 213 and first protrusions 214, the first recesses 213 protruding toward the top surface of the extraction plate 21 and the first protrusions 214 protruding toward the bottom surface of the extraction plate 21.

[0072] It should be noted that the top and bottom surfaces of the extraction plate 21 are two opposite sides of the extraction plate 21. The top surface of the extraction plate 21 refers to the side of the extraction plate 21 that is closer to the upper part of the tower body, and the bottom surface of the extraction plate 21 refers to the side of the extraction plate 21 that is closer to the lower part of the tower body. The sieve holes 211 are set through the top and bottom surfaces of the extraction plate 21.

[0073] This embodiment of the present disclosure provides a plurality of intersecting and continuously arranged first recesses 213 and first protrusions 214 in the extraction plate 21 to guide the two-phase fluid to flow in layers by utilizing the shapes of the first recesses 213 and first protrusions 214, thereby optimizing the fluid distribution, improving the interface clarity, and reducing backmixing and eddy current phenomena that occur in the two-phase fluid during the extraction process, thereby reducing the risk of emulsification and improving the extraction efficiency and separation effect of the extraction device 101.

[0074] like Figure 5 As shown, in some embodiments, the orthographic projections of two adjacent extraction plates 21 in the extraction assembly on the bottom surface of the housing 1 overlap.

[0075] It should be noted that the bottom surface of shell 1 refers to the side of shell 1 that is at its lowest point in the vertical Y direction.

[0076] In this embodiment of the present disclosure, by overlapping the orthographic projections of two adjacent extraction plates 21 on the bottom surface of the housing 1, the contact surface between the extraction plate 21 and the liquid can be increased, thereby enhancing the cutting of the liquid by the extraction plate 21 and improving the mass transfer efficiency between the two liquid phases.

[0077] In some embodiments, the extraction plate 21 may be a spiral plate extending in a vertical Y-axis, and the extraction plate 21 may be provided with a plurality of through sieve holes 211.

[0078] This embodiment of the invention allows the extraction plate 21, which extends spirally along the vertical Y direction, to reciprocate in the vertical Y direction and / or rotate circumferentially. This enables the two liquid phases in the containment space to be fully mixed in all directions, thereby making the mass transfer between the two liquid phases more complete. This improves the stirring efficiency of the extraction plate 21 on the two liquid phases and enhances the extraction efficiency of the extraction device 101.

[0079] like Figure 1 As shown, in some embodiments, the extraction assembly may further include a transmission member 22 extending vertically along the Y direction. The middle part of the transmission member 22 is disposed in the receiving space, and both opposite ends of the transmission member 22 are disposed through the housing 1. The transmission member 22 is connected to the extraction plate 21.

[0080] The extraction device 101 may also include a drive unit 3, which is located at opposite ends of the housing 1 in the vertical Y direction. The drive shaft of the drive unit 3 is connected to opposite ends of the transmission unit 22 to drive the extraction assembly to move relative to the housing 1.

[0081] Specifically, in this embodiment, the two ends of the transmission member 22 pass through the top and bottom surfaces of the housing 1 respectively and are connected to the drive shaft of the drive member 3. Thus, the transmission member 22 and the extraction plate 21 can reciprocate and / or rotate in the circumferential direction relative to the housing 1 under the drive of the drive member 3, so as to promote mass transfer between the two liquid phases.

[0082] In some embodiments, the drive element 3 may be a motor.

[0083] like Figure 1 As shown, in some embodiments, a first liquid inlet 13 and a second liquid inlet 14 communicating with the accommodating space may be provided on the side wall of the housing 1.

[0084] The first liquid inlet 13 is located at the upper part of the shell 1 and is used to introduce the raw liquid into the containment space; the second liquid inlet 14 is located at the lower part of the shell 1 and is used to introduce water into the containment space.

[0085] Specifically, the housing 1 may include an extraction section 11 and two settling sections 12, which are located at opposite ends of the extraction section 11 in the vertical Y direction, and the settling sections 12 are connected to the extraction section 11.

[0086] The first liquid inlet 13 can be located at the top of the extraction section 11, the second liquid inlet 14 can be located at the bottom of the extraction section 11, and the extraction plate 21 reciprocates along the vertical Y direction within the extraction section 11.

[0087] It should be noted that the top of the extraction section 11 is located above the bottom of the extraction section 11 in the vertical Y direction.

[0088] By setting a settling section 12, the residence time of each phase in the settling section 12 can be extended, allowing the denser liquid (heavy phase) to settle to the bottom, while the less dense liquid (light phase) floats on top, which is conducive to the full separation of the two phases and improves the separation efficiency of the extraction device 101.

[0089] like Figure 1 As shown, in some embodiments, the side wall of the housing 1 is provided with a first outlet 15 and a second outlet 16 communicating with the receiving space. The first outlet 15 is located in the upper part of the housing 1 for discharging the wine product; the second outlet 16 is located in the lower part of the housing 1 for discharging the residual phase of the extract.

[0090] Specifically, in this embodiment of the present disclosure, the first outlet 15 may be located on the settling section 12 above the vertical Y direction of the extraction section 11, and the second outlet 16 may be located on the settling section 12 below the vertical Y direction of the extraction section 11.

[0091] In some embodiments, the first outlet 15 may be located on opposite sides of the housing 1 in the transverse X direction with the first inlet 13, and the second outlet 16 may be located on opposite sides of the housing 1 in the transverse X direction with the second inlet 14.

[0092] It should be noted that the extraction device 101 in this embodiment can introduce two liquid phases into the containment space through the first inlet 13 and the first outlet, and promote mass transfer between the two liquid phases by reciprocating and / or rotating the extraction plate 21 relative to the housing 1 in the vertical Y direction. After the mass transfer between the two liquid phases is completed, the extraction plate 21 is stopped to allow the two liquid phases to separate in the containment space, thereby facilitating the extraction of the product. When the two liquid phases are the original liquid and water, the residual extract can settle into the settling section 12 located below the vertical Y direction of the extraction section 11, and the wine product can be separated into the settling section 12 located above the vertical Y direction of the extraction section 11.

[0093] like Figure 6 As shown, in some embodiments, the settlement section 12 is provided with a plurality of settlement plates 23 inclined relative to the transverse direction X, and the plurality of settlement plates 23 can be arranged at intervals along the vertical direction Y. The settlement plates 23 are provided with a plurality of through holes arranged at intervals, and the through holes penetrate the settlement plates 23.

[0094] This embodiment of the present disclosure provides multiple settling plates 23 within the settling section 12, and multiple through holes on the settling plates 23 to facilitate the flow of the liquid phase between the multiple settling plates 23, thereby increasing the effective settling area between the two phases, promoting the coalescence and phase separation of the dispersed phase droplets, shortening the separation time, reducing the amount of one liquid phase entrained by another liquid phase, thereby improving the extraction efficiency of the extraction device 101 and enabling the extraction device 101 to be suitable for high flow rate conditions.

[0095] Furthermore, in some embodiments, the settling plate 23 may include a plurality of intersecting and continuously arranged second recesses 231 and second protrusions 232, wherein the second recesses 231 protrude toward the top surface of the settling plate 23 and the second protrusions 232 protrude toward the bottom surface of the settling plate 23.

[0096] It should be noted that the top and bottom surfaces of the settling plate 23 are two opposite sides of the settling plate 23. The top surface of the settling plate 23 refers to the side of the settling plate 23 that is closer to the upper part of the tower body, and the bottom surface of the settling plate 23 refers to the side of the settling plate 23 that is closer to the lower part of the tower body. Through holes are provided through the top and bottom surfaces of the settling plate 23 to facilitate the flow of liquid on the top and bottom surfaces of multiple settling plates 23.

[0097] This embodiment of the present disclosure provides a plurality of intersecting and continuously arranged second recesses 231 and second protrusions 232 in the extraction plate 21. The shapes of the second recesses 231 and second protrusions 232 are used to increase the effective settling area of ​​the two liquid phases and extend the flow path of the two liquid phases on the extraction plate 21, thereby promoting the coalescence and phase separation of the dispersed phase droplets. This reduces the amount of one liquid phase entrained by the other liquid phase while shortening the separation time, thereby improving the extraction efficiency of the extraction device 101 and making the extraction device 101 suitable for high flow rate conditions.

[0098] like Figure 6 As shown, in some embodiments, the settling plate 23 located above the extraction section 11 is inclined upward in a direction away from the center of the housing 1, and the settling plate 23 located below the extraction section 11 is inclined downward in a direction away from the center of the housing 1.

[0099] Specifically, such as Figures 6 to 7 As shown, the vertical Y-section of the settling plate 23 located above the extraction section 11 can be approximately V-shaped, and the settling plate 23 can be arranged around the central axis of the shell 1. The vertical Y-section of the settling plate 23 located below the extraction section 11 can be approximately inverted V-shaped, and the settling plate 23 can be arranged around the central axis of the shell 1.

[0100] In some embodiments, the tilt angle of the settling plate 23 is adjustable.

[0101] Specifically, the embodiments of this disclosure can dynamically adjust the tilt angle of the electric actuator to adapt to different flow rates or phase changes within the housing 1, thereby enhancing the operational flexibility of the extraction equipment 101 and improving its ability to cope with fluctuations in operating conditions.

[0102] In some embodiments, the housing 1 and the extraction assembly can both be made of pure copper. When the extracted product is a wine, pure copper can be used to replace the methyl sulfide in the wine, thereby enhancing the flavor of the wine product.

[0103] like Figure 8 As shown, this disclosure also provides an extraction system, which includes at least any of the extraction devices 101 described above, the extraction device 101 being used to extract the original liquid and then to obtain a wine product.

[0104] It should be noted that, as Figures 9 to 10As shown, in relevant extraction systems, extractive distillation column 110 is typically used to extract the raw liquid. Extractive distillation column 110 utilizes the difference in boiling points of volatile components to achieve separation. Therefore, extractive distillation column 110 often includes structures such as condensers, reboilers, reflux tanks, and reflux pumps to perform continuous pressure-swing azeotropic distillation of the liquid within the column. The operation process of continuous pressure-swing azeotropic distillation in extractive distillation column 110 is not only complex but also requires numerous pieces of equipment, resulting in extremely high overall manufacturing and maintenance costs for the extraction system, and making it difficult to control.

[0105] This embodiment of the invention uses an extraction device 101 to extract wine products within an extraction system. The extraction relies on the affinity between the wine mixture and the solvent in the two phases. By reciprocating vertically (Y) and / or rotating circumferentially relative to the housing 1, the extraction plate 21 agitates and disperses the two counter-current liquid phases within the containment space, promoting mass transfer and separation. Therefore, the extraction process of the extraction device 101 in this embodiment does not require a vapor phase, heating steam within the housing 1 is unnecessary, and condensate reflux is not required outside the housing 1. This eliminates the need for steam and circulating cooling water energy consumption, thereby reducing material costs, maintenance costs, and operational economics associated with condensers, reboilers, reflux tanks, reflux pumps, and related operating platforms, electrical systems, and automation equipment. This significantly reduces the manufacturing and operating costs of the extraction device 101. Furthermore, the extraction device 101 in this embodiment simplifies the operation of the extraction system, thereby reducing the control complexity of the extraction system.
