Description

Technical Field

[0001] This utility model relates to the field of tea filtration technology, and in particular to a filtration device for tea beverage processing. Background Technology

[0002] In the tea beverage processing, filtration is a crucial step in ensuring product quality. Its core function is to remove tea dregs, debris, colloidal impurities, and other impurities from the tea extract, ensuring the beverage is clear, transparent, and has a smooth taste. As consumers' demands for tea beverage quality continue to rise, and as industrial production pursues higher efficiency and automation, the performance of filtration equipment directly impacts product qualification rates, energy consumption, and the stability of subsequent processing.

[0003] For example, a double-layer filter for tea beverage extraction process disclosed in CN222400498U specifically relates to the field of tea beverage filtration technology. It includes a filter, a sealed top cover, a support base, a sealing element, a first filter barrel, a first filter screen, a second filter screen, a second internal thread, a second filter barrel, a third external thread, and a mounting protrusion, which facilitates the addition of tea leaves and prevents the tea leaves from floating inside the filter during tea beverage extraction, thus making it inconvenient to clean the tea leaves.

[0004] The aforementioned equipment has shortcomings in practical use. Because the tea leaves can only be placed statically in the second filter tank, the extraction process relies entirely on natural liquid permeation. This method limits the contact area and efficiency between the tea leaves and water, resulting in low extraction efficiency. To achieve the desired extraction effect, the overall extraction time must be extended. Secondly, during the prolonged natural permeation process, uneven extraction occurs between the upper and lower layers of tea leaves in the second filter tank. The upper layer of tea leaves, being at the rear of the liquid permeation path, is prone to insufficient water supply and remains in a semi-soaked state, ultimately leading to incomplete extraction of effective components and insufficient release of flavor substances. Meanwhile, the lower layer of tea leaves, being at the front of the liquid permeation path for an extended period, is prone to excessive extraction of bitter substances and may result in an overly strong flavor and unbalanced taste due to over-extraction. Therefore, a filtration device for tea beverage processing needs to be designed.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0029] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1-7 As shown, the tea beverage processing filtration device provided in this embodiment of the present invention includes a storage component 1, which includes a base plate 11 and a storage cylinder 12 disposed on the base plate 11. The storage cylinder 12 is used to store filtered tea beverages, and the storage cylinder 12 is fixedly connected to the base plate 11 through a support cover 13. Meanwhile, a filtration component 3 is disposed inside the storage cylinder 12. The filtration component 3 includes a fine filtration section disposed inside the storage cylinder 12. The fine filtration section is supported by a bottom cover 32 inside the storage cylinder 12. The bottom cover 32 has a structural shape adapted to the internal space of the storage cylinder 12 and has an annular groove 321 on it.

[0031] Furthermore, a first filter cartridge 33 is inserted into the slot 321. A ring-shaped sealing ring 331 is provided near the bottom surface of the first filter cartridge 33. Utilizing the elastic deformation and sealing characteristics of the sealing ring 331, the first filter cartridge 33 can be tightly inserted into the slot 321, forming a stable and sealed connection structure. Simultaneously, four sets of symmetrical fastening parts 322 are provided circumferentially on the surface of the bottom cover 32. These fastening parts 322 are made of deformable plastic material, possessing a certain degree of elasticity and clamping adaptability. Correspondingly, fasteners 34 adapted to the fastening parts 322 are fixedly installed at corresponding positions on the first filter cartridge 33. When the first filter cartridge 33 is inserted into the slot 321, the fastening parts 322 and the fasteners 34 interact, further reinforcing the installation stability of the first filter cartridge 33, ensuring the reliability of the filter cartridge structure during filtration, and preventing displacement or loosening due to liquid impact, which could affect the filtration effect.

[0032] Furthermore, a coarse filtration section 35 is provided inside the storage cylinder 12 for filtering tea beverages and sealing the top of the first filter cylinder 33. The coarse filtration section 35 includes symmetrical half-filter cylinder 1 351 and half-filter cylinder 2 352, which together form the main space of the coarse filtration. A docking part 353 is provided on both sides where the half-filter cylinder 1 351 and half-filter cylinder 2 352 fit together. When the two are joined, the docking parts 353 of the half-filter cylinder 1 351 and half-filter cylinder 2 352 come into contact with each other, and a sealing gasket (not shown in the figure) is provided at the contact position to ensure the sealing of the joint. At the same time, a sealing ring 354 is provided on the half-filter cylinder 1 351 and half-filter cylinder 2 352 near the top outer surface to enhance the compatibility and sealing with the top sealing part.

[0033] Furthermore, a sealing section is provided inside the storage cylinder 12 at the top of the coarse filtration section 35. This sealing section is centered on the top cover 37 at the top of the coarse filtration section 35. The top cover 37 fits and covers the top of the first filter cylinder 33, forming a top-closed structure. A fixing sleeve 39 is integrally provided on the bottom surface of the top cover 37. The fixing sleeve 39 has an annular structure that fits the size of the top of the coarse filtration section 35. Correspondingly, sliding blocks 355 are symmetrically provided on the first half-filter cylinder 351 and the second half-filter cylinder 352. The inner wall of the fixing sleeve 39 is provided with a fastening groove 391 that fits the sliding block 355.

[0034] When the coarse filter section 35 is installed, after the first half-filter cartridge 351 and the second half-filter cartridge 352 are spliced ​​together, they are slidably engaged into the corresponding engagement groove 391 of the fixing sleeve 39 by the sliding fastener 355, thus initially achieving a positioning connection. In addition, a wing bolt 310 is threaded onto the surface of the fixing sleeve 39. The wing bolt 310 is made of food-grade stainless steel. After the coarse filter section 35 is slidably engaged into the fixing sleeve 39 by the sliding fastener 355 and the sealing ring 354, tightening the wing bolt 310 can further lock the connection between the coarse filter section 35 and the sealing section, ensuring the stability of the overall structure during filtration operations and preventing loosening and leakage problems due to liquid impact.

[0035] A sealing cover 36 is connected to the top cover 37 away from the fixed sleeve 39 via a connector 38. The sealing cover 36 is used to seal the top of the storage cylinder 12. At the same time, a support step is provided on the top of the storage cylinder 12 for the sealing cover 36 to overlap near the edge, forming a preliminary positioning support structure. A rod (not shown in the figure) is fixedly installed at the bottom of the sealing cover 36. A through hole is opened on the support step for the rod to pass through. The rod and the through hole cooperate to further restrict the horizontal displacement of the sealing cover 36. Furthermore, a sealing ring 4 is provided at the contact position between the sealing cover 36 and the support step. The elastic deformation of the sealing ring 4 fills the gap, ensuring the sealing effect of the top of the storage cylinder 12 and preventing liquid leakage or external impurities from entering during the tea beverage processing.

[0036] Meanwhile, a drive assembly 4 is provided on the base plate 11. This drive assembly 4 is used to stir the tea leaves inside the coarse filtration section 35 to optimize the extraction and filtration process. Specifically, the drive assembly 4 includes a support 41 fixedly installed on the base plate 11 in a vertical position. The support 41 serves as the main support body, and a controller 42 is fixedly installed on it to integrate control signals and coordinate the operation of the components. A drive unit 43 is fixedly installed at the top of the support 41. The drive unit 43 is a bevel gear set. The drive assembly 4 (refer to the equipment power transmission logic, the bevel gear is adapted for vertical space power steering) has a lead screw 44 fixedly installed at the center of the driven gear.

[0037] To ensure the rotational stability of the lead screw 44, a pad (not shown in the figure, used to bear the axial force of the lead screw 44) is integrally installed on the bracket 41 and connected to the bearing at one end of the lead screw 44, forming the basic transmission structure of the drive assembly 4.

[0038] Furthermore, two sets of guide rods 45 are provided between the pad and the drive unit 43. The guide rods 45 are arranged parallel to the lead screw 44, providing a running track for the subsequent sliding components. A sliding seat 46 is threaded onto the lead screw 44. The sliding seat 46 is synchronously and movably sleeved on the two sets of guide rods 45. Vertical lifting and lowering along the guide rods 45 is achieved by rotating the lead screw 44. A support 47 is fixedly installed on the side of the sliding seat 46, and a motor 48 is fixedly installed on the support 47. The output end of the motor 48 is connected to a stirring shaft 410 through a coupling 49. One end of the stirring shaft 410 has a stirring blade (not shown in the figure) and is located inside the coarse filter unit 35 near the bottom, which can stir the tea leaves and promote extraction.

[0039] Meanwhile, the sealing cover 36 is connected to the bearing of the stirring shaft 410, which not only ensures the rotational freedom of the stirring shaft 410, but also maintains the top sealing of the coarse filter section 35 with the help of the sealing cover 36, so that the driving stirring and filtering sealing functions can work together.

[0040] Furthermore, a water supply assembly 2 is provided on the base plate 11. This water supply assembly 2 is suitable for supplying water into the storage cylinder 12 to provide basic liquid raw materials for tea beverage processing. Specifically, the water supply assembly 2 includes a water pump 21 fixedly installed on the base plate 11. The water pump 21 serves as a power source and is connected to an inlet pipe 22. The inlet pipe 22 is suitable for connecting to external water supply equipment (such as a water tank, water pipe network, etc.) to introduce clean water. At the same time, an outlet pipe 23 is also connected to the inlet pipe 22. The outlet pipe 23 passes through the support cover 13 and extends into the storage cylinder 12. With the power of the water pump 21, external water can be transported to the processing space inside the storage cylinder 12 to ensure the liquid supply for the extraction and filtration processes.

[0041] In addition, a support is provided at the bottom of the inner wall of the storage cylinder 12 for supporting the fine filtration section. The support is centered on a support platform 31 fixedly installed at the bottom of the inner wall of the storage cylinder 12. The bottom of the support platform 31 has a concave structure, which can not only adapt to the internal space of the storage cylinder 12, but also provide a stable bearing surface for the bottom cover 32. Furthermore, a notch 311 is provided on the surface of the support platform 31. The notch 311 serves as a water flow channel, which is suitable for water source that is introduced through the water outlet pipe 23 to be poured into the storage cylinder 12, so that the water source can smoothly enter the processing area where the fine filtration section is located.

[0042] Correspondingly, the bottom surface of the bottom cover 32 has an inner groove, which fits into the surface of the support platform 31 to form an embedded installation structure. To enhance the sealing performance, a sealing ring 323 is provided at the contact position between the inner groove and the support platform 31. With the help of the elastic deformation of the sealing ring 323, the gap between the two can be filled to prevent liquid leakage and ensure a stable pressure environment for filtration and extraction.

[0043] Meanwhile, a valve 14 is connected to the support cover 13. The valve 14 serves as a liquid discharge control component. One end of the valve is connected to a right-angle tube 141. One end of the right-angle tube 141 extends into the interior of the storage cylinder 12, and the position of the tube opening corresponds to the liquid collection area inside the storage cylinder 12 after filtration. When the tea beverage completes the extraction and filtration process, the valve 14 is opened, and the completely filtered tea beverage can be discharged from the storage cylinder 12 along the right-angle tube 141, realizing the collection of finished products and the emptying of the equipment, which is convenient for subsequent cleaning and maintenance, and makes the liquid inlet, filtration and discharge links of the entire tea beverage processing process form a complete closed loop.

[0044] Working principle: In use, first disassemble the coarse filter section 35, and splice the first half filter cylinder 351 and the second half filter cylinder 352 (sealed by the docking part 354 and the sealing gasket), and put the tea to be processed into it; then slide the coarse filter section 35 into the fixing sleeve 39 below the top cover 37 using the sliding buckle block 355 and the sealing ring 353, and tighten the wing bolt 310 to complete the sealing and fixing. At the same time, the first filter cylinder 33 of the fine filter section is sealed by the sealing ring 331 and the buckling part 322 and the buckling groove 321 of the bottom cover 32. The bottom cover 32 fits into the bottom support platform 31 of the storage cylinder 12 through the inner groove and the sealing ring 323. The sealing cover 36 covers the top of the storage cylinder 12. The insertion rod and the sealing ring 4 ensure the top seal, completing the loading of the equipment and the sealing assembly of the components.

[0045] Water supply component 2 is activated, and water pump 21 draws water from the outside through inlet pipe 22 and sends it into storage cylinder 12 through outlet pipe 23. Drive component 4 operates synchronously, and drive unit 43 (bevel gear set) drives lead screw 44 to rotate. Sliding seat 46 moves down along guide rod 45, so that motor 48, stirring shaft 410 and stirring blade extend into coarse filter section 35. Motor 48 drives stirring blade to rotate, stirring and mixing tea leaves and water in coarse filter section 35 to promote extraction. After preliminary filtration through filter holes in coarse filter section 35, the mixture enters first filter cylinder 33, and then undergoes secondary filtration through fine filter section. Impurities are retained in filter cylinder, and the filtered tea beverage is collected at the bottom of storage cylinder 12.

[0046] When extraction and filtration reach the preset time, the drive component 4 and water supply component 2 are turned off, and the valve 14 on the support cover 13 is opened. The filtered tea beverage at the bottom of the storage cylinder 12 is discharged through the right-angle pipe 141, realizing the collection of the finished product. If cleaning is required in the future, the sealing components are disassembled in reverse, the residue in the coarse and fine filtration sections is removed, and the equipment is reset to prepare for the next processing, thus realizing the continuous processing of tea beverages.
