[0002] Ultrafiltration devices are mainly used for separation and purification in the wine-making process. Through the filtering effect of ultrafiltration membranes, impurities, suspended matter, microorganisms and other macromolecular substances in the wine can be efficiently intercepted, while allowing pure wine to pass through. This not only improves the clarity and transparency of the wine, but also improves the taste and flavor of the wine, while extending the shelf life of the wine.

[0003] When the ultrafiltration device used for wine making is separating and storing the wine, the wine is introduced from one end of the feed main pipe. The wine then flows through each ultrafiltration membrane in order from near to far. However, due to the long design length of the feed main pipe, the wine is unevenly distributed to each ultrafiltration membrane. The ultrafiltration membrane closer to the water inlet will receive more water flow than the ultrafiltration membrane farther away. As the wine continues to enter, this uneven distribution problem is further aggravated. The pressure on the ultrafiltration membrane close to one end of the feed main pipe gradually increases, causing it to be in an overloaded operating state. This situation will not only have an adverse effect on the overall performance of the ultrafiltration device, such as performance abnormalities, but will also shorten the service life of the ultrafiltration membrane.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Combine Figure 1-Figure 5 As shown, the present invention is an ultrafiltration device for wine making, comprising a frame 1, on which are arranged several rows of ultrafiltration membrane assemblies 2 for filtering wine, a feed main pipe 3, on which are arranged several feed branch pipes 4, and further comprising:

[0038] A connecting piece 5, one end of which is connected to the feed branch pipe 4, and the other end of which is connected to the ultrafiltration membrane assembly 2, and the number and distribution position of the connecting piece 5 are adapted to the ultrafiltration membrane assembly 2;

[0039] An opening control member 6 is provided on the connecting member 5 and is used to change the flow resistance of the fluid flowing through the connecting member 5;

[0040] Transmission assembly 7, which is disposed on the connecting member 5 and interconnected with the opening control member 6;

[0041] The regulating mechanism 8 is arranged on the connecting piece 5 and is interconnected with the transmission component 7. Under the drive of the regulating mechanism 8, the flow rate and pressure obtained by each feed branch pipe 4 can be adjusted through the transmission component 7 and the opening control component 6 to ensure that the water pressure in the feed branch pipe 4 is evenly distributed.

[0042] During the wine-making process, the wine is first introduced into the device through the feed main pipe 3. A plurality of feed branch pipes 4 are provided on the feed main pipe 3. These feed branch pipes 4 are responsible for distributing the wine to each ultrafiltration membrane assembly 2. Each feed branch pipe 4 is connected to the corresponding ultrafiltration membrane assembly 2 through a connecting piece 5. The number and distribution position of the connecting piece 5 are determined according to the number and layout of the ultrafiltration membrane assemblies 2 to ensure that each ultrafiltration membrane assembly 2 can obtain the supply of wine. An opening control piece 6 is provided on the connecting piece 5. The function of the opening control piece 6 is to change the flow resistance flowing through the connecting piece 5, thereby adjusting the flow rate of wine passing through the connecting piece. By adjusting the opening of the opening control piece 6, the amount of wine received by each ultrafiltration membrane assembly 2 can be controlled to avoid overloading of some ultrafiltration membrane assemblies 2 due to receiving too much wine. Load operation, in order to achieve precise adjustment of the opening control member 6, the device is also equipped with a transmission component 7 and an adjustment mechanism 8. The transmission component 7 is connected to the opening control member 6, and can transmit the driving force generated by the adjustment mechanism 8 to the opening control member 6, thereby changing its opening. The adjustment mechanism 8 is responsible for generating this driving force and accurately controlling the transmission component 7 and the opening control member 6 according to the preset adjustment strategy. In actual operation, the adjustment mechanism 8 will dynamically adjust the transmission component 7 and the opening control member 6 according to the wine flow and pressure in the feed main pipe 3 and the working status of each ultrafiltration membrane component 2 to ensure that the flow and pressure obtained by each feed branch pipe 4 are uniform. In this way, each ultrafiltration membrane component 2 can withstand appropriate pressure and achieve efficient and stable filtration operation.

[0043] In a preferred embodiment, the present invention can be further configured as follows: Figure 2 、 Figure 3 As shown; the connecting piece 5 includes a connecting pipe 51 and a mounting pipe 52, and both ends of each mounting pipe 52 are provided with a connecting pipe 51, one of the connecting pipes 51 is communicated with the feed branch pipe 4, and the other connecting pipe 51 is communicated with the ultrafiltration membrane assembly 2, wherein the connecting pipe 51 and the mounting pipe 52 are integrally formed, and both ends of each mounting pipe 52 are provided with a connecting pipe 51, one of the connecting pipes 51 is responsible for introducing the wine in the feed branch pipe 4 into the mounting pipe 52, and the other connecting pipe 51 is responsible for leading the wine from the mounting pipe 52 to the corresponding ultrafiltration membrane assembly 2, this design allows the wine to flow smoothly The wine flows smoothly between the feed branch pipe 4 and the ultrafiltration membrane assembly 2, while ensuring the uniformity and stability of the flow. The one-piece molding arrangement further enhances the structural strength and sealing performance of the connecting piece 5. Since there is no seam or connection point between the connecting pipe 51 and the mounting pipe 52, the risk of leakage can be greatly reduced, ensuring that the wine will not be lost due to leakage during the flow. In addition, the one-piece molding structure also makes the connecting piece 5 more durable and can withstand greater pressure and flow, thereby extending the service life of the entire ultrafiltration device. At the same time, the shape of the entire mounting pipe 52 is similar to the shape of a tire in the prior art.

[0044] In a preferred embodiment, the present invention can be further configured as follows: Figure 3 、 Figure 4 、 Figure 5 As shown; the opening control member 6 includes:

[0045] The ring body 61 is fixedly mounted on the inner side of the mounting tube 52 and is adapted to the aperture of the connecting tube 51;

[0046] Rotating shafts 62 , which are fixedly mounted on the outside of the ring body 61 , wherein each ring body 61 is provided with five rotating shafts 62 ; and

[0047] The opening and closing blades 63 are rotatably arranged on the outside of the rotating shaft 62, wherein the opening and closing blades 63 can rotate axially with the rotating shaft 62 as the base point. In the ultrafiltration device for wine making, the opening control member 6 is a key component for regulating the flow of wine flowing through the connecting member 5. Its design is crucial for achieving precise control of the flow and uniform distribution of pressure. The opening control member 6 is mainly composed of three parts: a ring body 61, a rotating shaft 62 and an opening and closing blade 63. The ring body 61 is fixedly mounted on the inner side of the mounting tube 52, and its aperture is adapted to the aperture of the connecting tube 51 to ensure that the wine can pass smoothly. The rotating shaft 62 is fixedly mounted on the outside of the ring body 61. Five rotating shafts 62 are set on each ring body 61. These rotating shafts 62 are evenly distributed to provide rotation of the opening and closing blades 63. It provides a stable support point, and the opening and closing blades 63 are rotatably set on the outside of the rotating shaft 62. They can rotate axially with the rotating shaft 62 as the base point. When the flow needs to be adjusted, the rotating shaft 62 is driven to rotate, and then the opening and closing blades 63 are driven to rotate. The rotation of the opening and closing blades 63 will change the angle between them, thereby adjusting the flow area and realizing precise control of the flow of wine flowing through the connecting piece 5. Specifically, when the opening and closing blades 63 are fully opened, the flow area is the largest and the wine flow is also the largest; when the opening and closing blades 63 are gradually closed, the flow area decreases and the wine flow also decreases. By precisely controlling the rotation angle of the opening and closing blades 63, continuous and smooth adjustment of the flow can be achieved, thereby meeting the needs of different flow rates and pressures in the wine making process.

[0048] In a preferred embodiment, the present invention can be further configured as follows: Figure 3 、 Figure 4As shown; a magnetic rubber sealing gasket is provided at the edge of the opening and closing blade 63, and two adjacent opening and closing blades 63 can be attracted to each other through the magnetic rubber sealing gasket, wherein the five opening and closing blades 63 on each ring body 61 can seal the opening of the ring body 61 when they contact each other. When the flow needs to be completely closed or the opening of the ring body 61 needs to be sealed, the five opening and closing blades 63 on each ring body 61 will be rotated to a position of contact with each other. At this time, due to the presence of the magnetic rubber sealing gasket at the edge of the opening and closing blade 63, the two adjacent opening and closing blades 63 will be tightly attracted to each other to form a continuous sealing surface, which can effectively prevent the leakage of wine and ensure that when the device is in the closed state, the opening of the ring body 61 is completely blocked to achieve the expected sealing effect. The use of the magnetic rubber sealing gasket not only improves the sealing performance between the opening and closing blades 63, but also enhances the reliability and durability of the entire opening control component 6. Since the magnetic rubber has good elasticity and corrosion resistance, it can maintain a stable sealing effect for a long time and can maintain a good working condition even under harsh working conditions.

[0049] In a preferred embodiment, the present invention can be further configured as follows: Figure 3 、 Figure 4 As shown; the transmission assembly 7 includes:

[0050] The rotating ring 71 is rotatably disposed on the inner side of the mounting tube 52 , wherein the rotating ring 71 and the ring body 61 are coaxially disposed;

[0051] The hinge seat 72 is fixedly mounted on the inner side of the rotating ring 71 , wherein each rotating ring 71 is provided with five hinge seats 72 ; and

[0052] The pull rod 73 has one end hinged on the surface of the hinge seat 72, and the other end hinged on the surface of the adjacent opening and closing blades 63. The rotating ring 71 is rotatably arranged on the inner side of the mounting tube 52 and is coaxially arranged with the ring body 61. This design ensures that the rotation of the rotating ring 71 can directly drive the ring body 61 and the opening and closing blades 63 thereon to rotate synchronously, thereby realizing the regulation of the flow rate. On the inner side of the rotating ring 71, a hinge seat 72 is fixedly installed. Each rotating ring 71 is provided with five hinge seats 72. These hinge seats 72 are evenly distributed, providing a stable support point for the hinge of the pull rod 73. The pull rod 73 is a key component of the transmission assembly 7, and one end of the hinge seat 72 is hinged. It is connected to the surface of the hinge seat 72, and the other end is hinged to the surface of the adjacent opening and closing blade 63. This hinge method enables the pull rod 73 to drive the opening and closing blade 63 to rotate through the transmission of the hinge seat 72 when the rotating ring 71 rotates. When adjustment is required, the rotating ring 71 is driven to rotate. As the rotating ring 71 rotates, the hinge seat 72 will drive the pull rod 73 to move. Since the other end of the pull rod 73 is hinged to the surface of the opening and closing blade 63, the movement of the pull rod 73 will be converted into the rotation of the opening and closing blade 63. By precisely controlling the rotation angle of the rotating ring 71, the rotation angle of the opening and closing blade 63 can be precisely controlled, thereby achieving precise adjustment of the flow rate.

[0053] In a preferred embodiment, the present invention can be further configured as follows: Figure 3 、 Figure 4As shown; five arc-shaped sliding holes 9 distributed in an annular shape and at equal distances are processed on the surface of the rotating ring 71, and a sliding limit pin 10 is fixedly installed on the inner side of the mounting tube 52, wherein the number and distribution position of the sliding limit pin 10 are adapted to the arc-shaped sliding holes 9 one by one, and the sliding limit pin 10 is located on the inner side of the arc-shaped sliding hole 9. Five arc-shaped sliding holes 9 distributed in an annular shape and at equal distances are processed on the surface of the rotating ring 71. The design of these arc-shaped sliding holes 9 allows the rotating ring 71 to rotate to a certain extent on the inner side of the mounting tube 52, while limiting the trajectory and range of its rotation. The shape and distribution position of the arc-shaped sliding holes 9 have been carefully calculated to ensure that the rotating ring 71 can remain stable during rotation and will not be damaged or affect other parts due to excessive rotation. In order to ensure the normal operation of the components, sliding limit pins 10 that are matched one by one with the arc-shaped sliding holes 9 are fixedly installed on the inner side of the mounting tube 52. The number and distribution position of the sliding limit pins 10 are exactly the same as those of the arc-shaped sliding holes 9, ensuring that each arc-shaped sliding hole 9 has a corresponding sliding limit pin 10. The sliding limit pin 10 is located on the inner side of the arc-shaped sliding hole 9. When the rotating ring 71 rotates, the sliding limit pin 10 will slide in the arc-shaped sliding hole 9 to play a guiding and limiting role. Due to the close fit between the sliding limit pin 10 and the arc-shaped sliding hole 9, the rotation range of the rotating ring 71 is strictly limited to a predetermined angle. This design not only prevents the rotating ring 71 from being damaged due to excessive rotation, but also ensures the accuracy and stability of flow regulation.

[0054] In a preferred embodiment, the present invention can be further configured as follows: Figure 2 、 Figure 3 As shown; the adjustment mechanism 8 includes:

[0055] A synchronous rotating rod 81 , one end of which is fixedly mounted on the outside of the rotating ring 71 , and the other end of which passes through and extends to the outside of the mounting tube 52 ;

[0056] A fixing plate 82, which is fixedly mounted on the outside of the mounting tube 52, wherein the fixing plate 82 is further provided with a through hole 83 adapted to the motion trajectory of the synchronous rotating rod 81; and

[0057] The fixing bolt 84 is arranged on the fixing plate 82 and is connected to the synchronous rotating rod 81, wherein the fixing bolt 84 is located on the inner side of the through hole 83. One end of the synchronous rotating rod 81 is fixedly mounted on the outer side of the rotating ring 71, and the other end passes through and extends to the outer side of the mounting tube 52. This design allows the operator to conveniently operate the synchronous rotating rod 81 outside the mounting tube 52, thereby controlling the rotation of the rotating ring 71. When the operator rotates the synchronous rotating rod 81, the rotating ring 71 will rotate accordingly. Since the rotating ring 71 and the ring body 61 are coaxially arranged and connected to the opening and closing blades 63 through the hinge seat 72 and the pull rod 73 in the transmission assembly 7, the rotation of the rotating ring 71 will drive the pull rod 73 to move, thereby driving the opening and closing blades 63 to move. As the opening and closing blades 63 move, the opening of the ring body 61 will change, thereby changing the flow The flow resistance of the mounting tube 52 is used to achieve precise adjustment of the flow rate. After the adjustment is completed, the operator can fix the synchronous rotating rod 81 to the fixed plate 82 by means of the fixing bolt 84. The fixing bolt 84 is located on the inner side of the through hole 83. By tightening the fixing bolt 84, the further rotation of the synchronous rotating rod 81 can be effectively restricted, thereby limiting the position of the opening and closing blades 63 to ensure the accuracy and stability of the flow regulation. Through this design, the adjustment mechanism 8 can accurately control the flow of the feed branch pipe 4, so that each feed branch pipe 4 can obtain the required flow rate, thereby avoiding pressure differences caused by uneven flow. This not only helps to maintain the pressure stability in the feed branch pipe 4 and prevent pressure fluctuations caused by excessive or insufficient flow, but also avoids some feed branches 4 from being overloaded due to excessive pressure, thereby extending the service life of the feed branch pipe 4 and the ultrafiltration membrane assembly 2.

[0058] In a preferred embodiment, the present invention can be further configured as follows: Figure 3 、 Figure 4 As shown, two sealed bearings 11 are positioned between the mounting tube 52 and the rotating ring 71. The synchronous rotating rod 81 is located between these two sealed bearings 11. A connecting hole 12 is machined into the outer wall of the mounting tube 52 for the rotating rod 81 to rotate. The synchronous rotating rod 81 is located inside this connecting hole 12. As a key component in the ultrafiltration device, the mounting tube 52 must withstand the flow and pressure of the wine. To ensure smooth rotation of the rotating ring 71 within the mounting tube 52 while not affecting the flow of wine and preventing leakage, two sealed bearings 11 are strategically placed between the mounting tube 52 and the rotating ring 71. These two sealed bearings 11 not only provide the necessary rotational support but also effectively prevent wine leakage through their internal sealing structure. The synchronous rotating rod 81, serving as a bridge between the rotating ring 71 and the external operating mechanism, is strategically positioned between the two sealed bearings 11. This design ensures that wine does not leak out through the connecting hole 12.

[0059] The specific working principle of the ultrafiltration device for wine making in the utility model is as follows:

[0060] During the winemaking process, first, the wine is introduced into the ultrafiltration device through the main feed pipe 3. The main feed pipe 3 evenly distributes the wine to several feed branch pipes 4. Each feed branch pipe 4 is connected to a specific connecting piece 5. The connecting piece 5 consists of a connecting pipe 51 and a mounting pipe 52. They are integrally formed to ensure structural stability and fluid smoothness. Both ends of each mounting pipe 52 are connected to the connecting pipe 51, one end is connected to the feed branch pipe 4, and the other end is connected to the ultrafiltration membrane assembly 2, achieving precise delivery of the wine.

[0061] When the flow in each feed branch pipe 4 needs to be adjusted, the synchronous rotating rod 81 can be rotated, and the synchronous rotating rod 81 drives the rotating ring 71 to rotate, and the opening and closing blades 63 are driven to rotate and displace by the pull rod 73, thereby adjusting the opening of the opening of the ring body 61, and the flow resistance flowing through the mounting pipe 52 can be changed, thereby achieving the purpose of adjusting the flow, thereby accurately adjusting the flow of the feed branch pipe 4, so that each feed branch pipe 4 can obtain the required flow, thereby avoiding the pressure difference caused by uneven flow, keeping the pressure in the feed branch pipe 4 stable, and preventing pressure fluctuations caused by excessive or insufficient flow, and avoiding some feed branch pipes 4 from being overloaded due to excessive pressure, thereby extending the service life of the feed branch pipe 4 and the ultrafiltration membrane assembly 2, finally, by passing the fixing bolt 84 through the through hole 83 and fixing the synchronous rotating rod 81 to the fixing plate 82, the position of the synchronous rotating rod 81 and the opening and closing blades 63 can be limited to ensure the accuracy and stability of the adjustment;

[0062] In summary, the ultrafiltration device for wine making realizes precise regulation and stable control of the wine flow rate through the coordinated action of the feed main pipe 3, the feed branch pipe 4, the connecting piece 5, the opening control piece 6, the transmission assembly 7 and the adjusting mechanism 8. The operator can adjust the rotation angle of the opening and closing blades 63 through the adjusting mechanism 8 according to actual needs, thereby changing the opening at the opening of the ring body 61 and adjusting the flow resistance of the wine flowing through the connecting piece 5, so as to achieve the purpose of precisely regulating the flow rate of the feed branch pipe 4. This not only ensures that each ultrafiltration membrane assembly 2 can obtain an appropriate and stable wine flow rate, but also avoids the pressure difference caused by uneven flow and the pressure fluctuation caused by excessive or insufficient flow, thereby extending the service life of the feed branch pipe 4 and the ultrafiltration membrane assembly 2, and improving the operating efficiency and stability of the entire ultrafiltration device for wine making.
