Description

Technical Field

[0001] This utility model belongs to the field of bioengineering technology, specifically a biological enzyme stirring device. Background Technology

[0002] With the development of the field of bio-enzyme mixing equipment, various types of mixing equipment have been widely used in bio-enzyme preparation, fermentation, and related processes. However, these devices still have some problems in practical applications. For example, existing equipment has certain limitations in terms of mixing efficiency, mixing uniformity, and applicability, especially in scenarios involving high-viscosity materials or requiring multiphase mixing, making it difficult to meet the requirements for efficient and uniform mixing.

[0003] A search revealed a mixing and dispersing device for preparing bio-enzyme-modified baking powder, publication number CN114307762B, published on September 13, 2022. This device utilizes a lifting assembly, a base box, a moving assembly, and a dispersing assembly, employing a rotating drum and rotating plates within a groove to ensure thorough contact and dispersion of the baking powder, thus achieving a complete mixing and dispersion effect. However, this design is primarily optimized for the characteristics of baking powder, resulting in a complex structure and limited applicability, making it difficult to adapt to other types of bio-enzyme mixing needs. Furthermore, while this device prevents material waste, its mixing efficiency is low, potentially leading to uneven mixing when dealing with high-viscosity or large-volume materials, and the equipment maintenance cost is high.

[0004] A search revealed an enzymatic hydrolysis device for edible starch suspension, publication number CN115197837B, published on 2022-12-06. This device includes a horizontal enzymatic hydrolysis cylinder, a stirring assembly, and a shell. A guide groove guides the stirring blades, and a counter-stirring mechanism improves the mixing uniformity and efficiency of the enzymes and starch suspension. While this design is innovative in improving mixing efficiency, its stirring method relies on a fixed guide groove structure, resulting in poor flexibility and difficulty in adapting to the stirring requirements of different materials. Furthermore, the stirring effect may decrease due to wear and tear of mechanical parts during long-term operation, and its complex structure increases manufacturing and maintenance costs.

[0005] The aforementioned problems indicate that current commercially available bio-enzyme stirring equipment still falls short in terms of stirring efficiency, mixing uniformity, and applicability, making it difficult to fully meet the demands of modern bio-enzyme preparation processes for efficient, flexible, and stable stirring equipment. Therefore, this invention provides a bio-enzyme stirring device designed to overcome these shortcomings, improve stirring efficiency and mixing uniformity, and enhance the applicability and stability of the equipment to meet the needs of various application scenarios.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] This utility model relates to a biological enzyme stirring device, the structure of which mainly includes a stirring tank 1, a stirring assembly, a driving mechanism, and an auxiliary mixing assembly. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, the mixing tank 1 is a cylindrical hollow container with an inlet 10 on one side of its top and an outlet 11 on one side of its bottom. The outlet 11 is located diagonally below the inlet 10 to facilitate the loading and unloading of materials. Support frames 12 are symmetrically welded to the outer wall of the mixing tank 1. A control panel 13 is fixedly connected to one end of the support frame 12. Operating buttons are distributed on one side of the outer wall of the control panel 13 for controlling the operation of the equipment. A drive mechanism is fixedly installed on the top outer wall of the mixing tank 1. The drive mechanism includes a drive motor 5, a reducer 6, and a coupling. The drive motor 5 is bolted to the top outer wall of the mixing tank 1. The output shaft of the drive motor 5 is connected to the input end of the reducer 6 via the coupling. The output end of the reducer 6 is fixedly connected to the top end of the mixing shaft 2 via a key.

[0025] The stirring assembly 14 is installed inside the stirring tank 1. The stirring assembly includes a stirring shaft 2, stirring blades 3, an adjusting ring 4, a sliding groove 17, a limiting block 19, and a locking bolt 18. The stirring shaft 2 is arranged along the central axis of the stirring tank 1, with its top end penetrating through the top of the stirring tank 1 and fixedly connected to the output end of the drive mechanism. The bottom end of the stirring shaft 2 extends to the bottom of the stirring tank 1 but does not contact the bottom inner wall. Four stirring blades 3 are symmetrically distributed on the outer wall of the stirring shaft 2, and each stirring blade 3 is movably connected to the stirring shaft 2 through the adjusting ring 4. A sliding groove 17 is provided on the inner wall of the adjusting ring 4, and a limiting block 19 is fixedly connected to the outer wall of the stirring shaft 2 at the position corresponding to the sliding groove 17. The limiting block 19 is embedded in the sliding groove 17 and can slide up and down along the sliding groove 17. A threaded hole is provided on one side of the outer wall of the adjusting ring 4, and a locking bolt 18 is screwed into the threaded hole. The end of the locking bolt 18 abuts against the outer wall of the stirring shaft 2. By tightening or loosening the locking bolt 18, the adjusting ring 4 can be fixed or moved on the stirring shaft 2. The surface of the stirring blades 3 is provided with through holes 14 with a diameter of 5mm to 10mm. The outer wall of the adjusting ring 4 is provided with anti-slip texture, and its thickness is between 8mm and 12mm, which facilitates manual adjustment.

[0026] An auxiliary mixing assembly is installed on the bottom inner wall of the mixing tank 1. The auxiliary mixing assembly includes a base, a rotating disk 7, feeding rods 8, and a guide groove 9. The base is welded to the center of the bottom inner wall of the mixing tank 1. The outer ring of a bearing 16 is fixedly connected to the top inner wall of the base, and the inner ring of the bearing 16 is fixedly connected to the bottom center of the rotating disk 7, thereby enabling the rotation of the rotating disk 7. Six feeding rods 8 are evenly distributed on the outer wall of the rotating disk 7. A flexible scraper 15 is fixedly connected to the outer wall of each feeding rod 8, and one side of the flexible scraper 15 is attached to the inner wall of the mixing tank 1. A guide groove 9 is provided on the bottom inner wall of the mixing tank 1 corresponding to the position of the feeding rod 8. One end of the feeding rod 8 is embedded in the guide groove 9 and can slide along the guide groove 9.

[0027] In actual operation, the drive motor 5 drives the stirring shaft 2 to rotate via the reducer 6. The rotation of the stirring shaft 2 causes the stirring blades 3 to stir the material in the stirring tank 1. Since the stirring blades 3 are movably connected to the stirring shaft 2 via the adjusting ring 4, the adjusting ring 4 can be moved up and down along the slide groove 17 by loosening the locking bolt 18, thereby adjusting the position of the stirring blades 3 on the stirring shaft 2 to adapt to the stirring requirements of materials at different liquid levels. After adjustment, the locking bolt 18 is tightened to fix the adjusting ring 4 in the set position, ensuring that the stirring blades 3 remain stable during operation. The through holes 14 on the surface of the stirring blades 3 can reduce liquid flow resistance, improve stirring efficiency, and enhance mixing uniformity.

[0028] Simultaneously, the rotation of the stirring shaft 2 drives the rotating disk 7 to rotate via mechanical transmission. The rotation of the rotating disk 7 causes the material-pushing rod 8 to slide along the guide groove 9, thereby promoting the material at the bottom of the mixing tank 1 to form a circulating flow. The flexible scraper 15 on the outer wall of the material-pushing rod 8 can effectively clean the residual material on the inner wall of the mixing tank 1 during the sliding process, avoiding material deposition or retention, and further improving the mixing effect. The flexible scraper 15 also has a certain degree of elasticity, which can maintain a tight fit when in contact with the inner wall of the mixing tank 1, reducing material waste and lowering the frequency of equipment maintenance.

[0029] During operation, the operator starts the drive motor 5 via the operation buttons on the control panel 13. The drive motor 5 drives the stirring shaft 2 to rotate through the reducer 6. The rotation of the stirring shaft 2 drives the stirring blades 3 to stir the material. At the same time, the rotation of the rotating disk 7 causes the material-pushing rod 8 to slide along the guide groove 9, pushing the material to form an up-and-down circulating flow within the mixing tank 1. The position of the stirring blades 3 can be adjusted according to the liquid level of the material to ensure optimal stirring effect. After stirring is completed, the material is discharged from the discharge port 11. The flexible scraper 15 cleans the residual material on the inner wall of the mixing tank 1 during the sliding of the material-pushing rod 8, ensuring the cleanliness of the equipment.

[0030] In the above embodiments, the dimensions of the mixing tank 1 are designed according to actual application requirements, typically with a diameter between 500mm and 1000mm and a height between 800mm and 1500mm. The diameter of the stirring shaft 2 is between 30mm and 50mm, and its length matches the height of the mixing tank 1. There are four stirring blades 3, each with a length between 100mm and 200mm and a width between 50mm and 100mm. The thickness of the adjusting ring 4 is between 8mm and 12mm, and the anti-slip texture on its outer wall adopts a grid design to increase friction and facilitate manual adjustment. There are six feeding rods 8, each with a length between 150mm and 250mm. The thickness of the flexible scraper 15 is between 2mm and 5mm, and the material is food-grade silicone to meet the hygiene requirements of biological enzyme stirring.

[0031] As can be seen from the above specific embodiments, the bio-enzyme stirring equipment of this utility model achieves flexible adjustment of the position of the stirring blade 3 and efficient circulation of materials in the stirring tank 1 by optimizing the structural design of the stirring component and the auxiliary mixing component. It solves the shortcomings of existing bio-enzyme stirring equipment in terms of stirring efficiency, mixing uniformity and applicability, meets the usage requirements of high viscosity materials or multiphase mixing scenarios, and improves the flexibility and stability of the equipment.

[0032] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0033] First, before starting the equipment, the operator needs to adjust the position of the stirring blades 3 according to the actual process requirements. By manually loosening the locking bolts 18, the adjusting ring 4 moves up and down along the slide groove 17 to a suitable height. The limiting block 19 is embedded in the slide groove 17 and slides synchronously with the adjusting ring 4, ensuring a smooth and precise adjustment process. After adjustment, tighten the locking bolts 18 to fix the adjusting ring 4 in the set position to ensure that the stirring blades 3 remain stable during operation. This step achieves flexible positioning of the stirring blades 3 through the cooperation of the adjusting ring 4 and the slide groove 17, thereby adapting to the material stirring requirements at different liquid levels and avoiding uneven mixing caused by improper positioning of the stirring blades 3.

[0034] Subsequently, the operator starts the drive motor 5 via the button on the control panel 13. The drive motor 5 drives the stirring shaft 2 to rotate via the reducer 6. The rotational driving force of the stirring shaft 2 is transmitted to the stirring blades 3 through a key connection, causing them to stir the material in the mixing tank 1. The through holes 14 on the surface of the stirring blades 3 reduce the liquid flow resistance during stirring, allowing the material to form a more uniform flow state in the mixing tank 1, thereby improving mixing efficiency. In addition, the design of the through holes 14 can also promote shearing between materials, further enhancing the uniformity of mixing.

[0035] Meanwhile, the rotation of the stirring shaft 2 drives the rotating disk 7 to rotate via mechanical transmission. The rotation of the rotating disk 7 causes the material-pushing rod 8 to slide along the guide groove 9. One end of the material-pushing rod 8 is embedded in the guide groove 9 and moves along its trajectory, thereby promoting the material at the bottom of the mixing tank 1 to form a circulating flow. The flexible scraper 15 fixed to the outer wall of the material-pushing rod 8 closely adheres to the inner wall of the mixing tank 1 during the sliding process, effectively cleaning residual material and preventing material deposition or retention. The flexible scraper 15 is made of food-grade silicone material, which has a certain degree of elasticity and can maintain good adhesion when in contact with the inner wall of the mixing tank 1, reducing material waste and lowering the frequency of equipment maintenance.

[0036] During the mixing process, if the material viscosity is high or there is multiphase mixing, the through-hole 14 design of the stirring blade 3 and the circulatory pushing of the material rod 8 work together to significantly improve the mixing effect. The flexible adjustment function of the stirring blade 3 can optimize the mixing range for different liquid levels, while the sliding of the material rod 8 ensures the effective participation of the material at the bottom, avoiding the bottom sedimentation problem common in traditional equipment. This dual-action mechanism enables this invention to efficiently process high-viscosity or multiphase mixtures, meeting the needs of modern bio-enzyme preparation processes.

[0037] After mixing is complete, the operator turns off the drive motor 5 via the control panel 13, and the material is discharged from the outlet 11. During this process, the feeding rod 8 continues to slide along the guide groove 9, and the flexible scraper 15 performs a final cleaning of the inner wall of the mixing tank 1 to ensure that no residual material adheres. This design not only improves the cleanliness of the equipment but also reduces the amount of subsequent cleaning work, further enhancing the efficiency of the equipment.

[0038] In summary, this invention achieves efficient and uniform mixing by flexibly adjusting the stirring blades 3, optimizing the resistance design of the through-hole 14, and using the cyclical material flow driven by the material-pushing rod 8. This overcomes the shortcomings of existing equipment in terms of mixing efficiency, uniformity, and applicability. Furthermore, the introduction of the flexible scraper 15 effectively reduces material waste and equipment maintenance frequency, further enhancing the stability and practicality of the equipment.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
