Description

Technical Field

[0001] The present invention relates to the technical field of mineral drink preparation, and specifically to a device for preparing a mineral drink. Background Art

[0002] Mineral drinks (calcium, magnesium, and zinc drinks) are oral liquid preparations containing minerals required by the human body. As the core constituent element of bones and teeth, calcium can effectively prevent osteoporosis, promote children's growth and development, and maintain nerve conduction and muscle contraction functions. Magnesium participates in more than 300 enzyme reactions in the human body. It not only regulates the nervous system, relieves stress and anxiety, but also stabilizes the heart rhythm, soothes muscle fatigue, and synergistically promotes calcium absorption in an acidic environment, enhancing bone toughness. Zinc, as a component or activator of more than 200 enzymes, is widely involved in the metabolism of carbohydrates, fats, and proteins, maintaining the normal physiological functions of cells and the balance of metabolism, while improving taste sensitivity and metabolic functions. When the three work together, the calcium-magnesium combination can balance electrolytes and prevent cardiovascular diseases, and the zinc-magnesium linkage can enhance antioxidant capacity and scavenge free radicals that cause aging.

[0003] In the preparation process of existing mineral drink liquids, purified water needs to be first poured into a preparation tank, and then raw materials are put in and stirred to make the raw materials dissolve in the purified water. Then, it is filtered, the pH is adjusted, and finally sterilized and filled. For example, the Chinese patent document with the application number CN202211307386.1 has disclosed the above-mentioned preparation process of mineral drink liquids; In the above-mentioned preparation process of mineral oral liquids, the raw materials added to the preparation tank are all in powder form. Due to the small particle size of the powder, it has a large specific surface area, resulting in a small density and the ability to float on the water surface. When a large amount of raw material powder is added at one time, the powder will float on the liquid surface and form lumps. Conventional stirring devices are installed inside the preparation tank to stir the internal liquid, so the stirring effect on the suspended part on the surface is poor, and the dissolution effect between the raw materials and the purified water is poor. In order to optimize the situation of powder floating on the liquid surface and forming lumps, the Chinese patent document CN202411648247.4 has disclosed a preparation process of mineral oral liquids. By designing a discharging unit inside the preparation tank, the raw material powder can be evenly discharged onto the liquid surface before being mixed with the purified water, avoiding the situation of excessive powder discharge at one time resulting in powder floating on the liquid surface and forming lumps. With the cooperation of the stirring of the stirring unit, the fusion efficiency between the raw materials and the purified water can be improved; However, whether using the currently prevalent traditional stirring devices or adopting the above-mentioned stirring structure scheme to handle the mixing process of raw materials, when the raw materials are mixed with pure water, due to the density difference between solids and liquids, it still easily leads to the problems of stratification or precipitation during the material mixing process in the preparation tank. Although the above-mentioned structure scheme can effectively solve the problem of poor mixing effect of a single stirring mechanism, it still cannot achieve good uniform mixing for the materials that have sunk to the bottom.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: Please refer to Figure 1 - Figure 3, A preparation device for a mineral drink in the illustration, including a preparation tank 1 for configuring raw materials for preparing the mineral drink. A stirring shaft 101 is connected to the preparation tank 1 through motor drive. Three stirring blades 102 are fixedly connected to the outer side of the stirring shaft 101; it further includes: a mixing unit 2 for sucking, discharging and mixing liquids, which is fitted and fixed on the stirring blades 102. An installation cavity is provided inside the bottom of the preparation tank 1. The stirring shaft 101 is rotatably connected to the bottom of the preparation tank 1 through a bearing. A synchronization unit 3 is connected to the stirring shaft 101 in the installation cavity. A plurality of anti-settling units 4 that are linked with the synchronization unit 3 are installed on the inner bottom of the preparation tank 1; a fuel tank 6 is provided below the bottom of the preparation tank 1. A maintenance unit 5 for periodically and automatically maintaining the synchronization unit 3 is installed on the top of the fuel tank 6.

[0023] In this solution, the designed mixing unit 2 is combined with the existing structure of the stirring blades 102, which can significantly increase the contact area between the raw material powder and the purified water, making the mixing process of the raw material powder and the purified water more thorough, thus greatly improving the mixing effect. At the same time, the mixing unit 2 also has the function of sucking and discharging the upper, middle and lower layers of the liquid raw materials in the batching tank. It can perform intermittent absorption and mixing operations on each layer of the liquid raw materials and then discharge them, further enhancing the mixing uniformity of the liquid raw materials and ensuring the quality and taste of the mineral drink. While the stirring blades 102 are rotating, the anti-settling unit 4 is driven to move through the synchronization unit 3. The anti-settling unit 4 can effectively send the precipitated materials deposited at the bottom of the preparation tank 1 evenly upward, so that combined with the mixing unit 2, the materials at the bottom of the preparation tank 1 can be evenly mixed, effectively preventing the materials with a larger density from forming precipitates that are difficult to mix evenly at the bottom of the tank. In addition, the maintenance unit 5 can further perform regular automatic maintenance work on the synchronization unit 3, and can perform lubrication maintenance by means of the power transmitted by the stirring shaft 101 without stopping for maintenance, ensuring that the synchronization unit 3 can operate continuously and stably, thereby improving the reliability and efficiency of the use of the anti-settling unit 4.

[0024] Further, refer to Figure 4, the mixing unit 2 includes a circulation cylinder 21, a first piston 22, a piston rod 23 and a stirring plate 24. The circulation cylinder 21 is fixedly sleeved on the stirring blade 102. The first piston 22 is slidably connected in the circulation cylinder 21. The piston rod 23 is fixed at both ends of the first piston 22. The stirring plate 24 is fixedly connected to the bottom of the first piston 22 through the piston rod 23. A round block 25 is fixedly connected to the top of the first piston 22 through the piston rod 23. A spring 26 is provided between the round block 25 and the circulation cylinder 21. Flow holes 27 are formed on both sides of the circulation cylinder 21. The overall stirring plate 24 is arranged with the left side lower and the right side higher. The shape of the stirring plate 24 is wing-shaped and is completely immersed in the raw material liquid inside the preparation tank 1.

[0025] The principle of the mixing unit 2 for mixing raw material powder and purified water: First, the operator pours the raw material powder and purified water into the preparation tank 1. The operation of the motor drives the stirring blade 102 and the circulation cylinder 21 to rotate together through the stirring shaft 101. The rotation of the stirring blade 102 and the circulation cylinder 21 can increase the contact area between the raw material powder and the purified water, making the mixing process of the raw material powder and the purified water more thorough, thus greatly improving the mixing effect. At the same time, when the circulation cylinder 21 rotates, it will also drive the stirring plate 24 to rotate together, further improving the stirring effect. Moreover, the stirring plate 24 has a shape similar to that of a wing. When the stirring plate 24 moves at high speed in a fluid environment, due to the pressure difference between its upper and lower end faces, a thrust will be generated in the axial direction of the circulation cylinder 21. The generation of this thrust is due to the uneven pressure of the fluid on the upper and lower surfaces of the stirring plate 24. When the stirring plate 24 moves at high speed in the fluid, the fluid velocity on its upper surface is faster than that on the lower surface. According to Bernoulli's principle, the pressure on the side with faster flow velocity is low, while the pressure on the side with slower flow velocity is high. Therefore, the pressure on the upper surface of the stirring plate 24 is less than the pressure on the lower surface, thereby forming an upward thrust in the axial direction. The magnitude of this thrust depends on factors such as the shape, size, movement speed of the stirring plate 24 and the properties of the fluid, etc., and then drives the piston rod 23 and the first piston 22 to reciprocate in the circulation cylinder 21. During this process, the liquid in the preparation tank 1 can be sucked into the circulation cylinder 21 and circulated and discharged. At the same time, since the overall position of the circulation cylinder 21 is constantly changing, the upper, middle and lower layers of the liquid raw materials in the preparation tank 1 are sucked and discharged, ensuring that intermittent absorption and mixing operations can be performed on each layer of the liquid raw materials and then discharged, further enhancing the mixing uniformity of the liquid raw materials.

[0026] Further, refer to Figure 5, the synchronization unit 3 includes a large gear 31, a transmission gear 32 and a transmission rod 33. The large gear 31 is in the installation cavity and fixedly sleeved on the stirring shaft 101. The outer side of the large gear 31 is meshed and connected with a plurality of the transmission gears 32. The transmission rod 33 is fixedly sleeved in the middle hole of the transmission gear 32. The transmission rod 33 is rotationally connected to the bottom of the preparation tank 1 through a sealed bearing. One end of the transmission rod 33 extending into the interior of the preparation tank 1 is fixedly connected to the bottom of the anti-settling unit 4.

[0027] Among them, refer to Figure 5 , the anti-settling unit 4 includes a liquid suction cylinder 41, a rotating shaft 42, a conical liquid pushing piece 43 and a connecting column 44. The top of the liquid suction cylinder 41 is fixedly connected to the inner bottom of the preparation tank 1 through a plurality of the connecting columns 44. The rotating shaft 42 is rotationally connected to the inside of the liquid suction cylinder 41 through a bearing. The conical liquid pushing piece 43 is integrally arranged on the outer side of the rotating shaft 42. The bottom end of the rotating shaft 42 is fixedly connected to the top end of the transmission rod 33.

[0028] The principle of the synchronization unit 3 driving the anti-settling unit 4 to rotate: The stirring shaft 101 drives the large gear 31 to rotate. The large gear 31 drives a plurality of transmission gears 32 to rotate. The transmission gears 32 drive the transmission rod 33 to rotate. The transmission rod 33 drives the rotating shaft 42 to rotate. The rotating shaft 42 drives the conical liquid pushing piece 43 to rotate. The conical liquid pushing piece 43 is spiral. Therefore, when rotating, it can push the raw materials at the bottom of the preparation tank 1 to drain evenly from bottom to top. Thus, combined with the mixing unit 2, it can uniformly mix the materials at the bottom of the preparation tank 1, effectively preventing the materials with a larger density from forming precipitates that are difficult to mix evenly at the bottom of the tank.

[0029] Embodiment 2: Please refer to Figure 6 - Figure 8 and Figure 10 , this embodiment further describes Embodiment 1. The difference is that a maintenance unit 5 is added to effectively perform regular automatic maintenance on the synchronization unit 3.

[0030] Specifically, the maintenance unit 5 includes a sealing cylinder 51, a second piston 52, a reciprocating lead screw 53, a connecting member 54, and a switching member 55. The bottom of the sealing cylinder 51 is fixed to the top of the fuel tank 6. Both ends of the reciprocating lead screw 53 are rotatably connected to the upper and lower ends of the sealing cylinder 51 through sealing bearings. The second piston 52 is slidably connected in the sealing cylinder 51 and is threadedly sleeved on the outer side of the reciprocating lead screw 53. A first connecting shaft 511 is fixed to the bottom of the stirring shaft 101. A power connection is made between the top end of the reciprocating lead screw 53 and the first connecting shaft 511 through the connecting member 54. The switching member 55 is arranged on one side of the sealing cylinder 51. An oil inlet pipe 57 is fixedly inserted into the top of the fuel tank 6. One end of the oil inlet pipe 57 away from the fuel tank 6 is fixedly connected to the sealing cylinder 51 through a one-way valve. Above the large gear 31 and on the inner wall of the installation cavity, an annular pipe 56 is fixed. A plurality of oil holes 58 are evenly distributed at the bottom of the annular pipe 56. One side of the annular pipe 56 is fixed with an oil outlet pipe 59. One end of the oil outlet pipe 59 away from the annular pipe 56 penetrates through the bottom of the preparation tank 1 and is connected to the sealing cylinder 51 through a one-way valve. A plurality of limit posts 510 are also slidably sleeved on the second piston 52. Both ends of the limit posts 510 are fixed to the upper and lower ends of the inner wall of the sealing cylinder 51 respectively.

[0031] Principle of maintaining the transmission components on the synchronization unit 3: After the stirring shaft 101 drives the large gear 31 and the transmission gear 32 to rotate for a period of time, the switching member 55 is used to connect the connecting member 54 to the reciprocating lead screw 53 and the stirring shaft 101. In this way, when the stirring shaft 101 rotates, it will drive the reciprocating lead screw 53 to rotate. The reciprocating lead screw 53 drives the second piston 52 to reciprocate up and down in the sealing cylinder 51. As a result, the maintenance oil in the fuel tank 6 will first be sucked into the sealing cylinder 51 from the oil inlet pipe 57, and then discharged from the oil outlet pipe 59 into the annular pipe 56, and discharged from the oil holes 58 at the bottom of the annular pipe 56 and flow to the large gear 31 and the transmission gear 32, thereby playing a role in lubricating and maintaining the gears.

[0032] Meanwhile, the connecting member 54 includes a channel-shaped plate 541, a linkage shaft 542, a first spline rod 543, a second spline rod 544, a first sleeve 545 and a second sleeve 546. The linkage shaft 542 is rotatably connected to the top of the channel-shaped plate 541 through a bearing. The first spline rod 543 and the second spline rod 544 are respectively fixed to the top and bottom of the linkage shaft 542. The first sleeve 545 is fixed to the bottom of the first connecting shaft 511 and is slidably sleeved with the first spline rod 543. The second sleeve 546 is fixed to the top end of the reciprocating lead screw 53 and is slidably sleeved with the second spline rod 544. The switching member 55 is fixed to the outer side of the sealing cylinder 51. The switching member 55 includes a fixed collar 551, a driving motor 552, a second connecting shaft 553, a threaded column 554 and a limiting plate 555. The fixed collar 551 is fixedly sleeved on the outer side of the sealing cylinder 51. The driving motor 552 is fixed to the outer side of the fixed collar 551. The second connecting shaft 553 is fixedly connected to the driving motor 552 through a coupling. The threaded column 554 is fixed to the end of the second connecting shaft 553 away from the driving motor 552. The limiting plate 555 is rotatably connected to the second connecting shaft 553 through a bearing. One end of the limiting plate 555 is fixed to the outer wall of the sealing cylinder 51. The threaded column 554 is threadedly connected to one end of the bottom of the channel-shaped plate 541. The other end of the bottom of the channel-shaped plate 541 is slidably sleeved with a sliding block 556. The bottom end of the sliding block 556 is fixedly connected to the fixed collar 551 through a fixing plate.

[0033] Principle of power conversion: When maintenance is required, the driving motor 552 drives the second connecting shaft 553 to rotate, thereby driving the threaded column 554 to rotate. The threaded column 554 drives the channel-shaped plate 541 to move downward, thereby driving the second spline rod 544 to insert into the second sleeve 546. At this time, the first spline rod 543 and the first sleeve 545 will not separate, so that the linkage shaft 542, the first spline rod 543, the second spline rod 544, the first sleeve 545 and the second sleeve 546 are connected together, and then the connection between the first connecting shaft 511 and the reciprocating lead screw 53 is realized. The power required for maintenance work can be transmitted from the stirring shaft 101 to the reciprocating lead screw 53. After the maintenance is completed, the driving motor 552 rotates in reverse to drive the second spline rod 544 and the second sleeve 546 to disengage.

[0034] It should also be noted that: The driving motor 552 in this solution is equipped with a controller and a time timer. The time timer can be set according to the time interval required for maintenance. When it is time for maintenance, the controller will automatically control the driving motor 552 to rotate several circles, so as to play the role of automatic maintenance without manual intervention.

[0035] Embodiment 3: Please refer to Figure 9 andFigure 11 , this embodiment further illustrates other embodiments. The difference lies in optimizing the lubrication environment around the synchronization unit 3.

[0036] Specifically, a return pipe 61 is connected to the fuel tank 6. A filter screen 62 is provided in the return pipe 61. A jack 63 communicating with the installation cavity is opened at the bottom of the preparation tank 1. The top end of the return pipe 61 is fixedly inserted into the jack 63. The maintenance oil in the installation cavity will gather at the bottom of the installation cavity due to the action of gravity, and then flow back into the fuel tank 6 through the return pipe 61. The filter screen 62 filters out impurities, thus effectively recycling the maintenance oil and reducing the loss of the maintenance oil.

[0037] It should also be noted that an oil drainage plate 64 is fixed to the bottom of the large gear 31. The bottom of the oil drainage plate 64 is in contact with the bottom of the installation cavity. When the large gear 31 drives the oil drainage plate 64 to rotate, the oil drainage plate 64 will push the maintenance oil at the bottom of the installation cavity close to the pipe orifice of the return pipe 61, thereby accelerating the return efficiency of the maintenance oil.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
