Description

Technical Field

[0001] This invention relates to the field of filtration and separation technology, and more specifically, to a filtration and separation device and method for wine production. Background Technology

[0002] Currently, in the wine production process, the raw wine after fermentation usually contains large particulate impurities such as fruit skins, pulp residues, and grape seed fragments, as well as small particulate suspended impurities such as lees and yeast cells. The presence of these impurities will seriously affect the clarity and storage stability of the wine, so they must be effectively removed by filtration and separation equipment.

[0003] However, existing filtration equipment is prone to clogging of the mesh due to impurities adhering to the inner wall of the screen, resulting in decreased or even interrupted filtration efficiency and low continuous filtration efficiency.

[0004] In view of this, we propose a filtration and separation device for wine production that can achieve dynamic anti-clogging and continuous operation to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a filtration and separation device and method for wine production, in order to solve the problem mentioned in the background art that existing filtration devices are prone to clogging of the mesh due to impurities adhering to the inner wall of the screen, resulting in low continuous filtration efficiency.

[0006] To achieve the above objectives, the present invention provides a filtration and separation device for wine production, comprising a coarse filter section, wherein a feed pipe is connected to the center of one shaft end of the coarse filter section and is connected to an external wine pipeline through the feed pipe, and a fine filter section is connected to the lower end of the coarse filter section, wherein a discharge pipe is connected to the bottom side of the fine filter section, wherein a sieve assembly is provided inside the coarse filter section, and the coarse filter section can separate large particulate impurities in the wine through the sieve assembly, and collect and export the separated large particulate impurities, wherein a permeation assembly is provided inside the upper end of the fine filter section, and the fine filter section can separate small particulate impurities in the wine through the permeation assembly, and collect and export the separated small particulate impurities.

[0007] As a preferred embodiment of the present invention, the filtration assembly includes a cylindrical screen, the coarse filter section is rotatably connected to the cylindrical screen coaxially, and the two axial ends of the cylindrical screen are respectively rotatably connected to the inner walls of the two axial ends of the coarse filter section. The upper side of the inside of the cylindrical screen is provided with an upward-facing first collection hopper.

[0008] As a preferred embodiment of the present invention, a connecting water pipe is provided on the upper side of the outer side of the coarse filter section, which is connected to an external water pipe, and the inner end of the connecting water pipe is connected to a plurality of spray pipes that radially penetrate the upper side of the inner side of the coarse filter section and are located on the upper side of the outer side of the cylindrical screen. A first drive motor is provided at the center of the end of the coarse filter section away from the feed pipe.

[0009] As a preferred embodiment of the present invention, the output shaft of the first drive motor passes through the interior of the coarse filter section and is connected to the cylindrical screen. The lower side of the first collection hopper near the first drive motor is connected to an outlet pipe extending to the outside of the coarse filter section, and the outlet pipe is connected to a first impurity discharge pipe with an opening facing downward.

[0010] As a preferred embodiment of the present invention, a second motor is provided at the outer end of the first waste discharge pipe, and the output shaft of the second motor passes through the inside of the first waste discharge pipe and is connected to a spiral impeller. The spiral impeller is located inside the first collection hopper and the outlet pipe, and the spiral impeller is rotatably connected inside the first collection hopper and the outlet pipe.

[0011] As a preferred embodiment of the present invention, the filtration assembly includes a mounting plate. The mounting plate is connected to the upper inner wall of the coarse filtration section, and an opening communicating with the coarse filtration section and the fine filtration section is provided at the center of the mounting plate. Multiple concentric filter cylinders coaxial with the fine filtration section are connected to the lower end of the mounting plate, and a fixing plate connected to the inner wall of the fine filtration section is provided directly below the multiple filter cylinders. An upper separation plate is rotatably connected between the fixing plate and the multiple filter cylinders.

[0012] As a preferred embodiment of the present invention, the upper part of the upper separation plate is radially connected to multiple sets of centrifugal fan blades arranged concentrically. The outer ends of the multiple centrifugal fan blades are connected to multiple cleaning brush heads that are attached to the inner wall of the filter cylinder. The lower side of the multiple cleaning brush heads is provided with collection grooves that are concentrically opened on the upper part of the upper separation plate. The lower ends of the multiple filter cylinders are respectively snapped into the inner and outer sides of the multiple collection grooves. Multiple connecting frames are connected between the lower sides of the inner and outer inner walls of the multiple collection grooves.

[0013] As a preferred embodiment of the present invention, the lower end of the fixed plate is rotatably connected to a lower separation plate, and a connector is penetrating through the center of the lower separation plate. The connector penetrates the fixed plate and is connected to the lower end of the upper separation plate, and is rotatably connected to the fixed plate. The lower end of the connector is connected to a connecting shaft extending to the outside of the lower end of the fine filter section, and the lower end of the connecting shaft is connected to a third drive motor located outside the lower end of the fine filter section.

[0014] As a preferred embodiment of the present invention, the fixed plate, the upper separation plate and the lower separation plate are each provided with a plurality of transfer grooves, which are arranged in a staggered manner from top to bottom. The lower end of the lower separation plate is fitted with a second collection hopper that fits against the lower end of the fixed plate, and the lower end of the second collection hopper is connected to a second impurity pipe extending to the outside of the fine filter section. The connecting shaft passes through the interior of the second impurity pipe and is rotatably connected to the second impurity pipe.

[0015] A filtration and separation method for wine production includes the following steps:

[0016] Step 1: Coarse filtration. Wine is introduced into the coarse filtration section through the external wine pipe and feed pipe. The wine is initially coarsely filtered by the screening components to remove large particles of impurities. The coarsely filtered wine is then introduced into the fine filtration section, where the large particles of impurities are collected and removed.

[0017] Step 2: Fine filtration. The wine that has been coarsely filtered is further finely filtered through the permeation filter to remove small particulate impurities. The filtered wine is then discharged through the discharge pipe to the next process. At the same time, the small particulate impurities that have been filtered out are collected and discharged.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This invention uses a sieve filter assembly to perform preliminary coarse filtration of wine, filtering out large particulate impurities in the wine. It also uses centrifugal force to quickly transfer large particulate impurities (such as peel and pulp residue) attached to the inner wall from the bottom to the top. Combined with high-pressure water jet rinsing, it prevents impurities from clogging the mesh and ensures the continuity and high efficiency of the coarse filtration process.

[0020] 2. This invention further filters wine through a permeation filter assembly and uses centrifugal force to throw the wine out of the permeation filter cylinder, filtering out small particulate impurities in the wine. At the same time, a rotating cleaning brush head scrapes away small particulate impurities (such as lees and yeast cells) attached to the inner wall of the filter cylinder in real time, and automatically discharges them through a collection tank, realizing the separation of small particulate impurities and continuous self-cleaning of the filter cylinder, ensuring the efficiency of continuous fine filtration.

[0021] 3. This invention employs a transfer trough structure with staggered upper and lower separation plates and a fixed plate. The synchronous rotation of the upper and lower separation plates enables the switching of the impurity channel. When impurities enter the transfer trough inside the fixed plate, the lower outlet is closed. When impurities exit the transfer trough inside the fixed plate and enter the collection hopper, the upper opening is closed. This achieves the transfer of small particulate impurities from the upper separation plate to the collection hopper while blocking the direct connection between the interior of the upper separation plate and the interior of the collection hopper, preventing the wine from being accidentally carried out due to pressure difference and reducing wine loss.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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 invention.

[0033] Please see Figure 1-7As shown, this embodiment provides a filtration and separation device for wine production, including a coarse filter mounting plate 1. A feed pipe mounting plate 2 is connected to the center of one shaft end of the coarse filter mounting plate 1, and is connected to an external wine pipeline through the feed pipe mounting plate 2. A fine filter mounting plate 3 is connected to the lower end of the coarse filter mounting plate 1, and a discharge pipe mounting plate 4 is connected to the bottom side of the fine filter mounting plate 3. A sieve assembly is installed inside the coarse filter mounting plate 1, and the sieve assembly can filter large particulate impurities in the wine. The process involves separating and collecting large particulate impurities. The upper part of the fine filtration section mounting plate 3 is equipped with a permeation filter assembly. The fine filtration section mounting plate 3 can separate small particulate impurities in the wine through the permeation filter assembly and collect and export the separated small particulate impurities. During the wine production process, the raw wine after fermentation contains large particulate impurities such as fruit skin and pulp residues and grape seed fragments, as well as small particulate suspended impurities such as lees and yeast cells. These impurities need to be separated by filtration equipment to remove internal impurities in order to improve the clarity and storage stability of the wine.

[0034] Thus, the raw wine is introduced into the coarse filtration section installation plate 1 through the wine pipe and the feed pipe installation plate 2, and then into the screening assembly for preliminary coarse filtration. This filters out large particles of impurities such as fruit skin and pulp residue and grape seed fragments from the wine. The separated large particles of impurities are collected and then discharged into the coarse filtration section installation plate 1.

[0035] Furthermore, the filtered wine enters the fine filtration section mounting plate 3 through the coarse filtration section mounting plate 1, and then enters the permeation filter assembly inside the upper part of the fine filtration section mounting plate 3 for fine filtration. This filters and separates small suspended impurities such as lees and yeast cells from the wine. The separated small impurities are collected and then discharged into the fine filtration section mounting plate 3. At the same time, the finely filtered wine enters the bottom of the fine filtration section mounting plate 3 and is discharged through the discharge pipe mounting plate 4 to enter the next process.

[0036] like Figure 2 and Figure 3As shown, the mounting plate sieve assembly includes a cylindrical screen mounting plate 5. The cylindrical screen mounting plate 5 is rotatably connected coaxially inside the coarse filtration section mounting plate 1. The axial ends of the cylindrical screen mounting plate 5 are rotatably connected to the inner walls of the axial ends of the coarse filtration section mounting plate 1. A connecting water pipe mounting plate 7, connected to an external water pipe, is located on the upper outer side of the coarse filtration section mounting plate 1. Multiple spray pipe mounting plates 8, radially penetrating the upper inner side of the coarse filtration section mounting plate 1 and located on the upper outer side of the cylindrical screen mounting plate 5, are connected to the inner end of the connecting water pipe mounting plate 7. A first drive motor mounting plate 9 is located at the center of the end of the coarse filtration section mounting plate 1 away from the feed pipe mounting plate 2. The output shaft of the first drive motor mounting plate 9 passes through the interior of the coarse filtration section mounting plate 1 and connects to the cylindrical screen mounting plate 5. (The last sentence appears to be incomplete and possibly refers to a specific process for wine processing.) During the coarse filtration of the raw wine, the first drive motor mounting plate 9 is electrically connected to an external power source via a wiring harness. Activating the first drive motor mounting plate 9 causes the cylindrical screen mounting plate 5 to rotate inside the coarse filtration section mounting plate 1 via its output shaft. Since a filtration chamber is formed between the inner wall of the cylindrical screen mounting plate 5 and the coarse filtration section mounting plate 1, and this chamber is connected to the feed pipe mounting plate 2, the wine is directly introduced into the filtration chamber and drips onto the lower inner wall of the cylindrical screen mounting plate 5. At this point, large particles of impurities in the wine are blocked inside the cylindrical screen mounting plate 5 and adhere to its inner wall. Simultaneously, the wine liquid passes through the mesh of the cylindrical screen mounting plate 5 into the coarse filtration section mounting plate 1 and flows downwards into the fine filtration section mounting plate 3, thus completing the coarse filtration of the wine.

[0037] In this process, the wine drips downwards into the filter chamber onto the inner wall of the rotating cylindrical screen mounting plate 5. This allows the cylindrical screen mounting plate 5 to immediately transfer the filtered large particles of impurities from the lower end to the upper side, preventing large particles of impurities adhering to the inner wall of the cylindrical screen mounting plate 5 from clogging the mesh and hindering the passage of the wine liquid, thus ensuring the efficiency of the coarse filtration of the wine.

[0038] like Figure 4As shown, the mounting plate of the first collection hopper mounting plate 6, near the lower side of the mounting plate of the first drive motor mounting plate 9, is connected to the outlet pipe mounting plate 10 extending to the outside of the coarse filter mounting plate 1. The outlet pipe mounting plate 10 is connected to the outside of the first row of impurity pipe mounting plate 11 with an opening facing downwards. A second motor mounting plate 12 is located at the outer end of the first row of impurity pipe mounting plate 11, and the output shaft of the second motor mounting plate 12 passes through the inside of the first row of impurity pipe mounting plate 11, connecting to a spiral impeller mounting plate 13. The spiral impeller mounting plate 13 is located inside the first collection hopper mounting plate 6 and the outlet pipe mounting plate 10, and is rotatably connected to both. This allows for the collection and guidance of large particulate impurities filtered out. During the filtration process, the second motor mounting plate 12 is electrically connected to an external power source via a wiring harness. Starting the second motor mounting plate 12 causes the cylindrical screen mounting plate 5 to rotate inside the coarse filtration section mounting plate 1. Since the wine drips directly downwards into the filtration chamber and onto the lower inner wall of the cylindrical screen mounting plate 5, trapping large particles of impurities, these impurities adhere to the lower inner wall of the cylindrical screen mounting plate 5. Therefore, when the cylindrical screen mounting plate 5 rotates inside the coarse filtration section mounting plate 1, the large particles of impurities adhering to the inner wall of the cylindrical screen mounting plate 5 rotate with it and immediately move away from the lower end of the cylindrical screen mounting plate 5. This prevents impurities from clogging the mesh at the bottom of the cylindrical screen mounting plate 5, hindering the passage of wine liquid and ensuring the efficiency of the coarse filtration.

[0039] Furthermore, simultaneously, external water pipes introduce high-pressure water into the interior of multiple spray nozzle mounting plates 8 through the connecting water pipe mounting plate 7. The water is then sprayed through the openings at the inner ends of the multiple spray nozzle mounting plates 8 onto the upper outer side of the cylindrical screen mounting plate 5. The high-pressure water passes through the mesh of the cylindrical screen mounting plate 5, flushing large particles of impurities attached to the inner wall of the cylindrical screen mounting plate 5 towards the interior of the first collection hopper mounting plate 6. This removes the large particles of impurities from the inner wall of the cylindrical screen mounting plate 5 and collects them through the first collection hopper mounting plate 6. This ensures that the inner wall of the cylindrical screen mounting plate 5 remains clean when it rotates to the bottom again, achieving continuous coarse filtration of the wine and improving the efficiency of coarse filtration.

[0040] like Figure 2 , Figure 5 and Figure 6As shown, the mounting plate filtration assembly includes a mounting plate 14. The mounting plate 14 is connected to the inner wall of the upper end of the coarse filtration section mounting plate 1. An opening communicating with the coarse filtration section mounting plate 1 and the fine filtration section mounting plate 3 is provided at the center of the mounting plate 14. Multiple concentric filter cartridge mounting plates 15, coaxial with the fine filtration section mounting plate 3, are connected to the lower end of the mounting plate 14. A fixing plate 16, connected to the inner wall of the fine filtration section mounting plate 3, is positioned directly below the multiple filter cartridge mounting plates 15. The mounting plate 16 is positioned between the fixing plate 16 and the multiple filter cartridge mounting plates 15. A rotating upper separation plate mounting plate 17 is connected to the upper separation plate mounting plate. Multiple concentrically distributed centrifugal fan blade mounting plates 18 are radially connected to the upper end of the upper separation plate mounting plate 17. Multiple cleaning brush head mounting plates 19, which are attached to the inner wall of the filter cartridge mounting plate 15, are connected to the outer ends of each centrifugal fan blade mounting plate 18. Collection trough mounting plates 20, concentrically formed at the upper end of the upper separation plate mounting plate 17, are located on the lower sides of the multiple collection trough mounting plates 20. The lower ends of the multiple filter cartridge mounting plates 15 are respectively engaged with the inner and outer sides of the multiple collection trough mounting plates 20. The lower sides of the inner and outer inner walls of the multiple collection trough mounting plates 20 are connected... Multiple connecting brackets are connected. The lower end of the mounting plate 16 is rotatably connected to the lower separation plate mounting plate 21, and a connecting head mounting plate 22 passes through the center of the lower separation plate mounting plate 21. The connecting head mounting plate 22 passes through the mounting plate 16 and connects to the lower end of the upper separation plate mounting plate 17, and is rotatably connected to the mounting plate 16. The lower end of the connecting head mounting plate 22 is connected to a connecting shaft mounting plate 23 extending to the outside of the lower end of the fine filter section mounting plate 3. The lower end of the connecting shaft mounting plate 23 is connected to a third drive motor mounting plate 24 located outside the lower end of the fine filter section mounting plate 3. During the fine filtration of wine, the third drive motor mounting plate 24 is electrically connected to an external power source via a wiring harness. The upper separation plate mounting plate 17 is connected to the lower separation plate mounting plate 21 as a whole via the connector mounting plate 22, and is also connected to the connecting shaft mounting plate 23 via the connector mounting plate 22. When the third drive motor mounting plate 24 is activated, it drives the lower separation plate mounting plate 21 to rotate at the lower end of the fixed plate mounting plate 16 via the connecting shaft mounting plate 23, and drives the upper separation plate mounting plate 17 to rotate between the filter cartridge mounting plate 15 and the fixed plate mounting plate 16.Simultaneously, the upper separation plate mounting plate 17 drives multiple concentrically distributed centrifugal fan blade mounting plates 18 and cleaning brush head mounting plates 19 to rotate inside multiple filter cartridge mounting plates 15.

[0041] At this time, multiple centrifugal fan blade mounting plates 18 are radially connected and rotate between mounting plate 14 and upper separation plate 17, forming a centrifugal pump. The wine entering the fine filtration section mounting plate 3 enters the center of the centrifugal pump through the opening at the center of mounting plate 14, and under the drive of the centrifugal pump, an outward centrifugal force is generated, allowing the wine to be thrown outward by the centrifugal force and enter the fine filtration section mounting plate 3 through the multi-layer filter cartridge mounting plate 15. Small particulate impurities inside the wine are blocked on the inner wall of the filter cartridge mounting plate 15, thereby filtering and separating the small particulate impurities inside the wine, achieving fine filtration of the wine.

[0042] Small particles of impurities blocked on the inner wall of the filter cartridge mounting plate 15 will be removed by multiple cleaning brush heads mounted on the mounting plate 19 and fall into the upper separation plate mounting plate 17 under gravity. This process cleans the inner wall of the filter cartridge mounting plate 15, preventing blockage and ensuring continuous fine filtration of the wine.

[0043] In addition, the connecting frame inside the lower end of the multiple collection tank mounting plates 20 can connect the upper end of the upper separation plate mounting plate 17 into a whole, preventing the upper end of the upper separation plate mounting plate 17 from being separated, and the lower end of the filter cartridge mounting plate 15 can fit on the connecting frame, providing a stable limit between the filter cartridge mounting plate 15 and the upper separation plate mounting plate 17.

[0044] like Figures 5-7As shown, the mounting plates 16 (fixed plate), 17 (upper separation plate), and 21 (lower separation plate) each have multiple transfer slots 25 inside. These transfer slots are staggered from top to bottom. A second collection hopper 26 is fitted onto the lower end of the lower separation plate 21, fitting against the lower end of the fixed plate 16. The lower end of the second collection hopper 26 is connected to a second impurity pipe 27 extending to the outside of the fine filter section 3. A connecting shaft 23 passes through the second impurity pipe 27 and is rotatably connected to it. During the collection and removal of filtered small particulate impurities, the third drive motor 24 drives the upper separation plate 17 via the connecting shaft 23. The mounting plates 21 and 21 rotate synchronously at the upper and lower ends of the mounting plate 16. Since the multiple transfer groove mounting plates 25 located inside the mounting plates 16, 17, and 21 are staggered from top to bottom, the transfer groove mounting plates 25 inside the mounting plates 17 and 21 will successively overlap with the transfer groove mounting plates 25 inside the mounting plate 16 during rotation, and will connect with the upper and lower ends of the transfer groove mounting plates 25 inside the mounting plate 16. However, the transfer groove mounting plates 25 inside the mounting plate 16 will not simultaneously overlap with the transfer groove mounting plates 25 inside the mounting plates 17 and 21.

[0045] Specifically, as the transfer groove mounting plate 25 inside the upper separation plate mounting plate 17 gradually overlaps with the transfer groove mounting plate 25 inside the fixed plate mounting plate 16, the upper end of the transfer groove mounting plate 25 inside the fixed plate mounting plate 16 communicates with the interior of the upper separation plate mounting plate 17, and the lower end of the transfer groove mounting plate 25 inside the fixed plate mounting plate 16 is blocked by the lower separation plate mounting plate 21, and does not communicate with the second collection hopper mounting plate 26. This allows small particulate impurities inside the upper separation plate mounting plate 17 to enter the interior of the fixed plate mounting plate 16 under the action of gravity through the transfer groove mounting plate 25.

[0046] Furthermore, as the transfer groove mounting plate 25 inside the upper separating plate mounting plate 17 and the transfer groove mounting plate 25 inside the fixed plate mounting plate 16 gradually shifts away, the transfer groove mounting plate 25 inside the fixed plate mounting plate 16 is located between the upper separating plate mounting plate 17 and the lower separating plate mounting plate 21. The upper and lower ends of the transfer groove mounting plate 25 inside the fixed plate mounting plate 16 are respectively blocked by the upper separating plate mounting plate 17 and the lower separating plate mounting plate 21. When the transfer groove mounting plate 25 inside the fixed plate mounting plate 16 and the transfer groove mounting plate 25 inside the lower separating plate mounting plate 21... As the mounting plates 25 gradually overlap, the transfer groove mounting plate 25 inside the lower separation plate mounting plate 21 connects with the lower end of the transfer groove mounting plate 25 inside the fixed plate mounting plate 16. The upper end of the transfer groove mounting plate 25 inside the fixed plate mounting plate 16 is blocked by the upper separation plate mounting plate 17, preventing it from connecting with the upper separation plate mounting plate 17. This allows small particulate impurities inside the fixed plate mounting plate 16 to pass through the transfer groove mounting plate 25 under gravity and enter the second collection hopper mounting plate 26 for collection. Finally, they are introduced into the fine filter section mounting plate 3 through the second impurity pipe mounting plate 27.

[0047] Specifically, the transfer groove mounting plate 25 inside the fixed plate mounting plate 16 is not simultaneously connected to the transfer groove mounting plate 25 inside the upper separation plate mounting plate 17 and the lower separation plate mounting plate 21. This ensures that the upper separation plate mounting plate 17 is not directly connected to the second collection hopper mounting plate 26. Small particulate impurities inside the upper separation plate mounting plate 17 will not be sprayed into the second collection hopper mounting plate 26 due to the pressure difference between the upper separation plate mounting plate 17 and the second collection hopper mounting plate 26, thus preventing wine from being carried into the second collection hopper mounting plate 26 and causing loss.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.

10. A filtration and separation method for wine production according to any one of claims 1-9, comprising the following steps: Step 1: Coarse filtration. The wine is introduced into the coarse filtration section (1) through the external wine pipe and feed pipe (2). The wine is initially coarsely filtered through the sieve assembly to remove large particles of impurities. The coarsely filtered wine is then introduced into the fine filtration section (3), where the large particles of impurities are collected and discharged. Step 2: Fine filtration. The wine that has been coarsely filtered is further finely filtered through the permeation filter to remove small particulate impurities. The filtered wine is then discharged through the discharge pipe (4) to the next process. At the same time, the small particulate impurities that have been filtered out are collected and discharged.
