[0002] In beverage production, filtration is typically required to ensure the taste, safety, and quality of the beverages, removing impurities, microorganisms, and other harmful substances. Currently, traditional membrane filtration devices mostly use fixed filter modules. While effective, these modules often develop dead zones in the filtration channels due to their installation method and location over long-term use, leading to uneven filtration and affecting the overall effect. Furthermore, the short lifespan of these filter modules necessitates frequent cleaning or replacement over extended periods. However, traditional cleaning methods are inconvenient and increase maintenance costs. Utility Model Content
[0003] The purpose of this invention is to provide a membrane filtration device for beverages. This device can further improve the comprehensiveness of the contact between the filter element and the solution in the filter container, as well as the dispersion and uniformity of impurities in the solution adhering to the filter element. Combined with the structural design and arrangement of the filter element, it is not easy to cause secondary pollution to the solution, and it will not form dead corners in filtration, thereby improving filtration efficiency and effectiveness. At the same time, it can also perform corresponding cleaning processes according to usage requirements, which is convenient to operate and further improves the flexibility and applicability of this device.
[0004] The technical solution adopted by this utility model to solve the above problems is:
[0005] A membrane filtration device for beverages includes a frame and a feeding tank mounted on it, and a filter assembly connected to the feeding tank via a pipe and a valve and a pressure pump mounted on it, forming a membrane filter body. The filter assembly includes a filter tank mounted on the frame and multiple filter elements installed inside the filter tank. The top of the filter tank is covered by a top cover with multiple locking parts. A pressure gauge and an exhaust valve are installed on the side below the top cover. The bottom has an inlet and an outlet connected to the pressure pump via a pipe. The filter elements are detachably mounted on multiple sets of pins rotatably mounted on the top cover and driven to rotate by a drive component connected to the pins mounted on the top cover.
[0006] Preferably, the top cover includes a detachably connected upper cover and a lower cover. A locking member is installed on the upper cover and connected to the filter barrel, and the lower cover is inserted into the filter barrel. The pin includes a first pin that rotates through a cavity in the lower cover and is connected to a driving component, and multiple sets of second pins arranged in an array around the periphery of the first pin. The top ends of the first and second pins are fitted with multiple sets of meshing gears in a cavity in the lower cover.
[0007] Preferably, multiple sets of first pin holes and second pin holes adapted to the rotation of the pin rod are respectively opened on the wall surface at the bottom of the upper cover and the bottom of the filter barrel.
[0008] Preferably, multiple sets of rubber rings are arranged at intervals on the side wall of the lower cover that contacts the inner wall of the filter barrel.

[0011] Compared with the prior art, this utility model has the following advantages and effects:
[0012] This utility model relates to a membrane filtration device for beverages. Compared to the fixed filtration modules in traditional membrane filters, this device features multiple filter cartridges located inside the filter tank within the main body of the membrane filter, which rotate during filtration under the drive of a driving component. This improves the comprehensiveness of contact between the filter cartridges and the solution inside the filter tank, as well as the dispersion and uniformity of impurities in the solution adhering to the filter cartridges. The structure and arrangement of the filter cartridges minimize secondary contamination of the solution and prevent the formation of filtration dead zones, further enhancing the filtration efficiency and effectiveness of the filtration assembly. Furthermore, the detachable connection between the top cover and the filter tank via a locking mechanism facilitates cleaning of the filter tank. The filter cartridges can be detachably connected to the pins using an interference fit, ensuring easy assembly and disassembly of the filter cartridges. This method facilitates the cleaning and replacement of filter elements, offering high operational speed. During cleaning, clean water or cleaning solution can be added to the feeding tank, allowing it to enter the filter cartridge through pipes and inlet under pressure. The drive unit's rotation speed can be appropriately increased, enabling some impurities adhering to the filter element to detach and mix under centrifugal force and the cleaning solution's action. These impurities are then partially discharged through the drain outlet and pipes. The cleaning process can be repeated depending on the turbidity of the discharged solution. Compared to disassembly and shutdown, this cleaning method offers better cleaning effectiveness, greater operational convenience, and higher cleaning efficiency. It can appropriately extend the filter element's lifespan, ensure its stability, and reduce operating costs, further enhancing the device's versatility and flexibility. Attached Figure Description

Detailed Implementation
[0017] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0018] See Figure 1-4 This embodiment relates to a membrane filtration device for beverages, comprising a frame 1 and a feeding tank 2 mounted on it, and a filter assembly 5 connected to the feeding tank 2 via a pipe 3 and a valve 31 and a pressure pump 4, forming a membrane filter body 100. The filter assembly 5 includes a filter tank 51 mounted on the frame 1 and multiple filter elements 52 installed inside the filter tank 51. The top of the filter tank 51 is covered by a top cover 54 via multiple locking parts 53. A pressure gauge 511 and an exhaust valve 512 are installed on the side below the top cover 54. The bottom is provided with an inlet 513 and an outlet 514 connected to the pressure pump 4 via the pipe 3. The filter elements 52 are detachably mounted on multiple sets of pins 55 rotatably mounted on the top cover 54 and driven to rotate by a drive component 56 connected to the pins 55 mounted on the top cover 54.
[0019] Specifically in this embodiment, such as Figure 1 The overall structure of the membrane filtration device for this type of beverage is shown, combined with... Figure 2-4As shown, during use, the filter element 52 commonly used in membrane filters can be structurally configured. Simultaneously, multiple sets of filter elements 52 of corresponding lengths can be inserted and installed using the mounting holes 521 in the middle and the multiple sets of pins 55 extending from below the top cover 54. The locking element 53 can be installed in multiple sets around the side of the top cover 54 using a snap-fit structure. The corresponding positions on the top periphery of the filter tank 51 provide locking parts 510 for engaging the locking element 53, further improving the ease of assembling and disassembling the top cover 54 from the top of the filter tank 51. In actual use, the beverage concentrate can be added into the feeding tank 2, while the pipe 3 connects to the bottom wall of the feeding tank 2. The connection method is set so that, under the action of the pressure pump 4, the beverage concentrate in the tank flows through the pipe 3 and the inlet 513 into the filter tank 51. Then, under the filtration action of multiple filter elements 52 inside the filter tank 51, it is discharged through the drain outlet 514 and its upper pipe 3 into the filter tank 51 for subsequent collection and processing. The pipe valve 31 installed on the pipe 3 facilitates the control of the internal liquid flow. The pressure gauge 511 installed on the side of the filter tank 51 facilitates real-time monitoring of the internal pressure of the filter tank 51 during the filtration process. Combined with the exhaust valve 512 on it, it facilitates the venting of air from the inside of the filter tank 51, ensuring the working stability and safety of the membrane filter body 100. Furthermore, during the filtration process... The drive unit 56 installed on the top cover 54 can drive multiple sets of pins 55 on the top cover 54 to rotate. Specifically, the drive method can be achieved by adding a planetary gear structure inside the top cover 54 to enable multiple sets of filter elements 52 on the pins 55 to rotate in the corresponding directions within the filter barrel 51. The pressure pump 4 and the drive unit 56 can be started and stopped by two control boxes 101 installed at corresponding positions on the frame 1 and connected to them respectively. The control box 101 connected to the drive unit 56 is equipped with an adjustment knob for speed adjustment. During filtration, the corresponding speed setting for the drive unit 56 to drive the filter elements 52 should be relatively low, so that the filter elements 52 have a tendency to rotate in a cycle. The diameter of the filter element 52 is set to ensure that adjacent filter elements 52 do not interfere with each other during rotation, while an appropriate gap is left with the inner wall of the filter canister 51 to ensure filtration stability and prevent impurities attached to the filter element 52 from falling off and causing secondary pollution to the internal solution. A second water inlet 32 is also provided on the pipe 3 connected to the water inlet 513 on the pressure pump 4, and a pipe valve 31 is also installed on the corresponding pipe 3 of the second water inlet 32. It can be directly connected to the external beverage concentrate storage tank according to the usage requirements. The two sets of pipe valves 31 installed on the corresponding pipes 3 of the water inlet 513 and the second water inlet 32 are used for on / off control to meet the needs of adding different solutions.Compared to the fixed filtration modules in traditional membrane filters, the membrane filtration device in this beverage features multiple filter elements 52 located inside the filter tank 51 of the filter assembly 5 on the main body 100 of the membrane filter. These elements rotate during filtration under the drive of the drive component 56. This further improves the comprehensiveness of contact between the filter elements 52 and the solution inside the filter tank 51, as well as the dispersion and uniformity of impurities in the solution adhering to the filter elements 52. The structural design and arrangement of the filter elements 52 minimize secondary contamination of the solution and prevent the formation of filtration dead zones, further enhancing the filtration efficiency and effectiveness of the filter assembly 5. Furthermore, the detachable connection between the top cover 54 and the filter tank 51 via the locking component 53 facilitates cleaning and other operations inside the filter tank 51. The filter elements 52 can be detachably connected to the pins 55 using an interference fit, ensuring easy installation and removal of the filter elements 52 from the pins 55. The process of cleaning and replacing the filter element 52 is quick and easy. During cleaning, clean water or cleaning solution can be added to the feeding tank 2, allowing it to enter the filter tank 51 through the pipe 3 and inlet 513 under the action of the pressure pump 4. At this time, the rotation speed of the drive component 56 can be appropriately increased, allowing some impurities attached to the filter element 52 to be detached and mixed by centrifugation and the cleaning solution during rotation. These impurities can then be partially discharged through the drain outlet 514 and its pipe 3. The cleaning process can be repeated depending on the turbidity of the discharged solution. Compared to the cleaning method of stopping and disassembling, this method offers a certain cleaning effect while providing greater operational convenience and cleaning efficiency. It can appropriately extend the service life of the filter element 52, ensure the stability of the filter element 52's function, and appropriately reduce operating costs, further improving the functionality and flexibility of this device.
[0020] See Figure 3-4The top cover 54 includes a detachably connected upper cover 541 and a lower cover 542. A locking member 53 is installed on the upper cover 541 and connected to the filter barrel 51, and the lower cover 542 is inserted into the filter barrel 51. The pin 55 includes a first pin 551 that passes through the cavity opened in the lower cover 542 and is rotatably connected to the driving component 56, and a plurality of second pins 552 arranged in an array around the periphery of the first pin 551. The top ends of the first pin 551 and the second pins 552 are fitted with a plurality of meshing sets in the cavity opened in the lower cover 542. Gear 57, the upper cover 541 and lower cover 542 can be detachably connected by multiple sets of bolts. Combined with the structural design and arrangement of the first pin 551 and the second pin 552, they can be installed through multiple sets of second mounting holes 5421 opened at corresponding positions on the lower cover 542. Simultaneously, multiple sets of gears 57 of the same specification and number of teeth are meshed and installed in the cavity of the lower cover 542 at the top ends of the first pin 551 and the second pin 552. After installation, the first pin 551 located in the middle of the lower cover 542... The top of component 1 can be placed in the third mounting hole 5411 opened at the corresponding position on the top cover 541. The drive component 56 can be installed on the top of the top cover 541 through bolts. At the same time, the corresponding drive shaft is inserted into the connecting hole 5511 opened at the top of the first pin 551. Under the drive of the drive component 56, the first pin 551 and its filter element 52 can be driven to rotate cyclically in the middle of the top cover 54. At the same time, under the meshing rotation of multiple sets of gears 57, multiple sets of second pins 552 and their multiple sets of filter elements 52 can be driven to rotate in the filter barrel 51. The upward synchronous rotation process, with the top cover 54 and its drive component 56 and pin 55 connected in this way, can further improve the structural detachability and disassembly flexibility of this device, making daily inspection and subsequent maintenance convenient and efficient. In addition, the unified specification of multiple sets of gears 57 can ensure the stability of the first pin 551 and multiple sets of second pins 552 rotating through the drive component 56 and the uniformity of their corresponding speeds, further improving the filtration effect and working stability of this device.
[0021] Multiple sets of first pin holes 5412 and second pin holes 515, adapted to the rotation of the pin rod 55, are respectively opened on the wall surface at the bottom of the upper cover 541 and the bottom of the filter barrel 51. Figure 2 and Figure 4As can be seen, when the upper cover 541 is placed on the lower cover 542, the top end of the pin 55 extending to an appropriate length above the gear 57 can be placed in the first pin hole 5412. On the one hand, this can improve the rotational stability of the gear 57 in the cavity of the lower cover 542 and reduce the phenomenon of gear 57 shifting. On the other hand, it can also combine the connection process of the bottom of the pin 55 in the multiple sets of second pin holes 515 opened on the bottom wall of the filter barrel 51, further improving the positional stability of the pin 55 and the filter element 52 during rotation.
[0022] Multiple sets of rubber rings 5422 are arranged at intervals on the side wall of the lower cover 542 that contacts the inner wall of the filter barrel 51. Figure 3 or Figure 4 As can be seen, the addition of multiple sets of rubber rings 5422 on the side wall corresponding to the lower cover 542 can further improve the connection effect between the top cover 54 and the filter barrel 51, and can also further improve the sealing effect inside the filter barrel 51, reducing the occurrence of solution leakage.
[0023] The filter assembly 5 also includes a filter cylinder 58 installed inside a filter barrel 51 located below the top cover 54 and surrounding multiple filter elements 52. The top of the filter cylinder 58 is open, and filter screens are provided on its sides and bottom. The filter screen located at the bottom of the filter barrel 51 has a third pin hole 581 adapted to the water inlet 513 and multiple sets of fourth pin holes 582 adapted to the pin rod 55. For details, please refer to [link / reference]. Figure 4The filter cartridge 58 shown has a structure where the filter screen at the bottom of the cartridge 58 can be configured with third pin holes 581 and multiple sets of fourth pin holes 582 at corresponding positions based on the water inlet 513 at the bottom of the filter barrel 51 and the corresponding positions of the pins 55 inside the filter barrel 51. The filter cartridge 58 can be installed inside the filter barrel 51, and the filter screen on its side can be positioned in the gap between the inner wall of the filter barrel 51 and the filter element 52. By adjusting the position of the filter cartridge 58, the third pin holes 581 and fourth pin holes 582 on the bottom filter screen can be aligned with the positions of the water inlet 513 and the second pin hole 515 at the bottom of the filter barrel 51, thus facilitating the installation of the top cover 54 and the multiple sets of pins 55 on it. The length of the filter element 52 on the pins 55 is set such that its bottom is aligned with... The filter screen at the bottom of the filter cartridge 58 has an appropriate gap. The height of the filter cartridge 58 is set so that when the top cover 54 is stably placed on top of the filter barrel 51, the top of the filter cartridge 58 and the bottom of the lower cover 542 just abut against each other. Combined with the structural addition and connection method of the filter cartridge 58, it has a certain positional stability in the filter barrel 51 and can further improve the filtration effect of the filter assembly 5. The filter screen at the bottom of the filter cartridge 58 can also effectively reduce the phenomenon of blockage of the drain outlet 514. In addition, the filter cartridge 58 can also effectively reduce the phenomenon of impurities in the solution sticking to the inner wall of the filter barrel 51. Combined with the connection method of the filter cartridge 58, it is also convenient to remove the impurities attached to the filter cartridge 58 from the filter barrel 51 for subsequent cleaning and other operations, meeting different usage needs.
[0024] The bottom of the feeding hopper 2 is provided with a second drain outlet 21 and is connected to a second pipe 3, and a second pipe valve 211 is installed on the second pipe 3. Figure 1 As can be seen, the opening of the second drain outlet 21 at the bottom of the feeding tank 2 and the addition of the second pipe 3 and the second pipe valve 211 can further improve the speed of the discharge of the solution inside the feeding tank 2, reduce the phenomenon of solution residue in the feeding tank, and facilitate the cleaning of the feeding tank 2 and other operations.
[0025] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
