Description

Technical Field

[0001] This utility model belongs to the field of concentration tank technology, specifically relating to a mixing mechanism for concentration tanks. Background Technology

[0002] In pharmaceutical and chemical industries, thorough mixing of materials is a crucial process for ensuring product homogeneity in concentrated preparation tank operations. Traditional mixing mechanisms typically employ a vertical stirring rod arranged along the tank's axis as the core mixing component, achieving material mixing through the rotational motion of the stirring paddle on a horizontal plane. However, this structure has significant limitations in practical applications: when handling multiphase materials with large density differences, components of different densities will exhibit vertical stratification under gravity, particularly with the interface persisting within a specific height range of the tank. Since traditional stirring rods can only perform two-dimensional planar mixing in the circumferential direction, they cannot effectively break up the vertical material stratification structure, leading to a significant reduction in mixing efficiency. Existing technologies typically compensate for this problem by extending the mixing time or increasing the stirring speed. However, this not only significantly increases energy consumption (experimental data shows an increase of over 40%), but also carries the risk of denaturation of heat-sensitive materials due to excessive shearing. Some improvements attempt to add inclined blades to the stirring rod, but due to the fixed blade installation angle and lack of axial motion components, a three-dimensional mixing effect cannot be achieved. Furthermore, a single stirring shaft structure easily creates a mixing blind zone in the central area of ​​the tank, especially when the material viscosity is high, this inadequate mixing in the central area is more pronounced. Therefore, there is an urgent need to develop a new mixing mechanism that can achieve three-dimensional mixing and effectively eliminate vertical stratification of materials. Utility Model Content

If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0025] like Figure 1-6 As shown, the mixing mechanism for the concentrated preparation tank includes a concentrated preparation tank body 1, a top cover plate 3 is provided on the top of the concentrated preparation tank body 1, a liquid inlet 5 is provided on the top cover plate 3, a liquid outlet 9 is provided on the bottom of the concentrated preparation tank body 1, a liquid storage tank bracket 4 is provided on the top cover plate 3, and a liquid storage tank 6 is supported and connected on the liquid storage tank bracket 4.

[0026] The bottom of the storage tank 6 is provided with an end pipe 13, and the end pipe 13 is fixedly connected to a sealing pipe 7. The sealing pipe 7 is rotatably connected to a conveying main pipe 12. The conveying main pipe 12 passes through the top cover plate 3 and extends into the interior of the concentration tank 1. A mixing drive mechanism 8 is provided on the top cover plate 3. The mixing drive mechanism 8 is used to drive the conveying main pipe 12 to rotate.

[0027] The conveying main pipe 12 extends into the interior of the concentration tank 1 and is connected to a feeding and mixing assembly 24 and a bottom scraper assembly 22. Multiple feeding and mixing assemblies 24 are provided and are equidistantly arranged along the length of the conveying main pipe 12. Each feeding and mixing assembly 24 includes a conveying branch pipe 29, one end of which is fixedly connected to and communicates with the conveying main pipe 12.

[0028] Furthermore, in one embodiment, the bottom of the storage tank 6 is generally conical, and the end pipe 13 is fixedly disposed in the middle of the conical bottom surface of the storage tank 6. The conical bottom allows the material in the storage tank 6 to smoothly pass through the end pipe 13 into the conveying main pipe 12, thereby conveying the material into the concentration tank 1 through the conveying main pipe 12 and the conveying branch pipe 29. At the same time, the mixing drive mechanism 8 drives the conveying main pipe 12 to rotate, thereby driving the feeding and mixing assembly 24 to rotate in the concentration tank 1 while conveying the material, so as to achieve the purpose of conveying the material and stirring at the same time. Compared with the material being input from only a fixed position, the mixing efficiency can be greatly improved. Moreover, multiple feeding and mixing assemblies 24 are equidistantly arranged along the length of the conveying main pipe 12, so that the material can be input at different height positions in the concentration tank 1 at the same time, further improving the efficiency of conveying and mixing.

[0029] Furthermore, in one embodiment, the mixing drive mechanism 8 includes a drive motor 18 mounted on the storage tank support 4, the drive motor 18 being connected to a drive gear 17, a driven gear 11 mounted on the conveying main pipe 12, and an intermediate gear 10 rotatably mounted on the top cover plate 3.

Specifically, when the drive motor 18 is working, the drive gear 17 drives the intermediate gear 10 to rotate, and the intermediate gear 10 drives the driven gear 11 to rotate, thereby driving the conveying main pipe 12 to rotate. This achieves rotational drive of the feeding and mixing assembly 24 and the bottom scraper assembly 22 within the concentration tank 1, enabling simultaneous operation of material conveying, mixing, and cleaning of bottom sediment accumulation.

During the rotation of the conveying main pipe 12, the second mixing rod 33 drives the second scraper 35 and the third scraper 34 to rotate together. The second scraper 35 performs scraping and cleaning operations on the side of the lower part of the inner cavity of the concentration tank 1, and the third scraper 34 performs scraping and cleaning operations on the bottom of the inner cavity of the concentration tank 1. At the same time, the inclined third scraper 34 can stir the material deposited at the bottom upward, thereby improving the mixing efficiency.

[0033] Furthermore, in one embodiment, a bottom support 23 is provided in the middle of the bottom surface of the inner cavity of the concentration tank 1, and the lower end of the conveying main pipe 12 is rotatably connected to the bottom support 23; the bottom support 23 supports and stabilizes the conveying main pipe 12, ensuring its stability during operation.

The support base plate can stably support the liquid storage tank bracket 4 and the liquid storage tank 6, avoiding excessive local pressure on the top cover plate 3; the structure is simple and reasonable, and the liquid storage tank 6 can be stably supported by the support rod 19.

[0035] Furthermore, in one embodiment, the top cover plate 3 is connected to the concentration tank 1 via a connecting assembly 2. The connecting assembly 2 includes an upper connecting seat 15 fixedly disposed on the top cover plate 3 and a lower connecting seat 14 fixedly disposed on the upper part of the concentration tank 1.

[0036] In summary, the mixing mechanism for a concentration tank of this utility model includes a storage tank 6 supported on a storage tank bracket 4. The bottom of the storage tank 6 is fixedly connected to a sealing pipe 7 via an end pipe 13. The sealing pipe 7 is rotatably connected to the upper end of a conveying main pipe 12, ensuring a tight seal at the connection point when the conveying main pipe 12 rotates. The conveying main pipe 12 extends into the concentration tank body 1, and its body is connected to a feeding and mixing assembly 24 and a bottom scraper assembly 22. Multiple feeding and mixing assemblies 24 are arranged equidistantly along the length of the conveying main pipe 12. A conveying branch pipe 29 within the feeding and mixing assembly 24 communicates with the conveying main pipe 12, and multiple conveying holes 26 are provided on the body of the conveying branch pipe 29. While the driving mechanism 8 drives the conveying main pipe 12 to rotate, the feeding and mixing components 24 at each height simultaneously convey materials into the concentration tank 1 through the corresponding conveying branch pipes 29.
