Description

Technical Field

[0001] This utility model belongs to the technical field of emulsion processing equipment, specifically relating to a stirring paddle for rosin emulsion production. Background Technology

[0002] In the production of rosin emulsions, the design of the agitator has a significant impact on product quality. Good agitation ensures that rosin is thoroughly and evenly mixed with the emulsifier during emulsification, improving the particle size distribution and stability of the emulsion.

[0003] Currently available agitators for rosin emulsion preparation present numerous problems. Traditional commercially available agitators have low mixing efficiency, resulting in slow material mixing and significantly extended production cycles and high costs. In large-scale rosin emulsion production, the low mixing efficiency requires considerable time to ensure uniform mixing of rosin with other components, severely limiting production efficiency and company capacity. Secondly, traditional agitators easily generate large amounts of foam during mixing. In rosin emulsion preparation, the presence of this foam severely impacts emulsion quality. Foam leads to uneven particle size distribution, affecting its performance in downstream applications. Foam also interferes with subsequent production processes; during packaging, foam can cause inaccurate metering, affecting product consistency and stability. To address the frequent foaming issues during emulsification, the conventional industrial practice is to add defoamers. Defoamers quickly reduce the local surface tension of foam, causing the foam film to rupture and thus achieving defoaming. However, defoamers easily interact with other components in the system, interfering with the emulsion's originally stable chemical structure and consequently affecting its performance.

[0004] To address the issue of defoamers affecting emulsion performance, patent application CN114288714B discloses an emulsion defoaming agitator. By placing agitator blades on an agitator disc, the interaction between the disc and blades reduces emulsion disturbance and air incorporation during agitation, thereby minimizing bubble formation. However, to achieve both increased agitation efficiency and reduced foaming, two agitator discs are used, making the gap between the blades and the discs difficult to clean and maintain.

[0005] Therefore, there is an urgent need for a stirring paddle for rosin emulsion production that is easy to clean and maintain, has high stirring efficiency, and has defoaming function. Summary of the Invention

[0006] The purpose of this invention is to solve at least the aforementioned defects and to provide advantages that will be described later.

[0007] To achieve these objectives and other advantages of this invention, a stirring paddle for rosin emulsion production is provided, comprising: a stirring shaft, a fixed plate, a first stirring paddle, and a second stirring paddle.

[0008] A fixing plate is connected to the end of the stirring shaft away from the drive device, and the long side of the fixing plate is aligned with the axial direction of the stirring shaft.

[0009] The first stirring paddle is a trapezoidal plate, and at least four of the first stirring paddles are provided, which are symmetrically distributed on both sides along the long side of the fixed plate.

[0010] The second stirring paddle is a rectangular plate. There are two second stirring paddles, and the two second stirring paddles will connect the first stirring paddles on both sides respectively. The second stirring paddle is connected to the side of the first stirring paddle away from the fixed plate.

[0011] In this configuration, the first stirring paddle and the fixed plate are not on the same plane, while the second stirring paddle and the fixed plate are on the same plane.

[0012] In the above solution, specifically, the stirring shaft, the fixed plate, the first stirring paddle, and the second stirring paddle are integrally formed. By combining the fixed plate, the first stirring paddle, and the second stirring paddle, and connecting the stirring shaft to the drive device during use, the drive device drives the stirring shaft, which in turn drives the stirring structure composed of the fixed plate, the first stirring paddle, and the second stirring paddle to stir the material. During the stirring process, the material flow path is affected by this stirring structure, achieving stirring in different directions and at different levels, improving the degree of mixing, enhancing the shearing and pushing effect on the material, avoiding the problem of uneven mixing in certain areas, improving the production efficiency and product quality of rosin emulsion, and ensuring product quality consistency; at the same time, it can effectively reduce the foam generated during the stirring process.

[0013] Preferably, the first stirring paddles on the same side are parallel, the angle between the first stirring paddle and the fixed plate is 15~35°, and the first stirring paddles on different sides of the fixed plate are not on the same plane.

[0014] In the above solution, by improving the angle of the first stirring paddle, more thorough mixing is achieved during the stirring process, further improving product quality and aiding in defoaming, thus reducing the impact of foam on the production process. By improving the angle between the first stirring paddle and the fixed plate, the shear force and pushing effect of the stirring paddle on the material during stirring are optimized, allowing the material to flow better at different levels and directions, avoiding dead zones in the material during stirring, promoting uniform mixing, enhancing defoaming ability, and improving stirring effect and product quality.

[0015] Preferably, the first stirring paddle is an isosceles trapezoidal structure, with the ratio of the height of the trapezoid to the length of the base being 1:1.5~2.5, and the base angle being 45~60°.

[0016] In the above scheme, by improving the structure of the first stirring paddle, it is better adapted to the stirring characteristics of rosin emulsion, generating more suitable shear force and material flow during the stirring process, improving stirring efficiency, ensuring the uniformity of material mixing in different areas, providing better stirring effect for the production of rosin emulsion, and also helping to defoam.

[0017] Preferably, it also includes a third stirring paddle; the third stirring paddle includes a stirring cylinder and a connecting rod; the stirring cylinder is a hollow conical cylinder with open ends, and the connecting rod connects the stirring cylinder to the fixed plate or the second stirring paddle.

[0018] Preferably, there are three third stirring paddles, which are evenly distributed at the end of the fixed plate away from or near the stirring shaft, and the included angle between adjacent connecting rods is 120°.

[0019] Preferably, there are two third stirring paddles, each located on the front and rear sides of the fixed plate and connected to the end of the fixed plate away from the stirring shaft; or the two third stirring paddles are connected to the two sides of the second stirring paddle away from the fixed plate.

[0020] Preferably, there are four third stirring paddles; two of the third stirring paddles are located on the front and rear sides of the fixed plate and connected to the end of the fixed plate away from the stirring shaft; the two third stirring paddles are connected to the two sides of the second stirring paddle away from the fixed plate.

[0021] Preferably, the number of third stirring paddles is five; wherein, three third stirring paddles are evenly distributed at the end of the fixed plate away from the stirring shaft or three third stirring paddles are evenly distributed at the end of the fixed plate close to the stirring shaft; two third stirring paddles are respectively connected to the two sides of the second stirring paddle away from the fixed plate.

[0022] Preferably, the number of third stirring paddles is six; wherein, three third stirring paddles are evenly distributed at the end of the fixed plate away from the stirring shaft; three third stirring paddles are evenly distributed at the end of the fixed plate close to the stirring shaft; and the third stirring paddles at both ends of the stirring shaft are staggered.

[0023] In the above solution, the addition of a third agitator increases the dimension of mixing. The even distribution of connecting rods and the special shape of the mixing drum create more flow patterns in the material during mixing, achieving multi-dimensional mixing, further breaking up material agglomeration, improving mixing effect and production efficiency, ensuring product quality, and achieving better defoaming. In actual production applications, the number and distribution of the third agitator can be adjusted to adapt to different scales of rosin emulsion production.

[0024] Preferably, the angle between the centerline of the stirring cylinder and the length direction of the connecting rod is 15~20°, and the diameter ratio of the first opening diameter to the second opening diameter of the stirring cylinder is 5:3~4.

[0025] In the above solution, by improving the structure of the mixing drum and connecting rod, the role of the mixing drum in the mixing process is optimized, making the material flow within the mixing drum more rational, forming unique vortices and flow paths, which helps to improve the uniformity and efficiency of mixing, while also improving the defoaming effect and ensuring the mixing effect of the rosin emulsion. Further limiting the structure of the mixing drum allows for better flow and mixing of materials within the drum, preventing blockages, improving mixing efficiency and product quality, and enhancing the defoaming effect.

[0040] Figure 1 This invention illustrates one implementation of a stirring paddle for rosin emulsion production, comprising: a stirring shaft 1, a fixed plate 2, a first stirring paddle 3, and a second stirring paddle 4.

[0041] A fixing plate 2 is connected to the end of the stirring shaft 1 away from the driving device, and the long side of the fixing plate 2 is aligned with the axial direction of the stirring shaft 1.

[0042] The first stirring paddle 3 is a trapezoidal plate, and at least four of the first stirring paddles 3 are provided. The first stirring paddles 3 are symmetrically distributed on both sides along the long side of the fixed plate 2.

[0043] The second stirring paddle 4 is a rectangular plate. There are two second stirring paddles 4, and the two second stirring paddles 4 will respectively connect the first stirring paddles 3 on both sides. The second stirring paddle 4 is connected to the side of the first stirring paddle 3 away from the fixed plate 2.

[0044] In this configuration, the first stirring paddle 3 and the fixed plate 2 are not on the same plane, while the second stirring paddle 4 and the fixed plate 2 are on the same plane.

[0045] Specifically, in this implementation scheme, the stirring shaft, the fixed plate, the first stirring paddle, and the second stirring paddle are integrally formed. By combining the structures of the fixed plate, the first stirring paddle, and the second stirring paddle, the stirring shaft is connected to a drive device during use. The drive device drives the stirring shaft, which in turn drives the stirring structure composed of the fixed plate, the first stirring paddle, and the second stirring paddle to stir the material. During the stirring process, the material flow path is affected by this stirring structure, achieving stirring in different directions and at different levels. This improves the degree of mixing, enhances the shearing and pushing effect on the material, avoids the problem of uneven mixing in certain areas, improves the production efficiency and product quality of rosin emulsion, and ensures product quality consistency. Simultaneously, it effectively reduces foam generated during the stirring process.

[0046] Furthermore, preferably, the first stirring paddles 3 on the same side are parallel, the angle between the first stirring paddle 3 and the fixed plate 2 is 15~35°, and the first stirring paddles 3 on different sides of the fixed plate 2 are not on the same plane.

[0047] This implementation scheme improves the angle of the first stirring paddle, enabling more thorough mixing during the stirring process, further enhancing product quality, and aiding in defoaming to reduce the impact of foam on the production process. By modifying the angle between the first stirring paddle and the fixed plate, the shearing force and pushing action of the stirring paddle on the material during stirring are optimized, allowing the material to flow better at different levels and directions, avoiding dead zones in the material during stirring, promoting uniform mixing, enhancing defoaming ability, and improving stirring effect and product quality.

[0048] Furthermore, the first stirring paddle 3 is an isosceles trapezoidal structure, with the height of the trapezoid to the length of the base being 1:1.5~2.5, and the base angle being 45~60°.

[0049] This implementation scheme improves the structure of the first stirring paddle to better adapt to the stirring characteristics of rosin emulsion, generates more suitable shear force and material flow during the stirring process, improves stirring efficiency, ensures uniform mixing of materials in different areas, provides better stirring effect for the production of rosin emulsion, and also helps to defoam.

[0050] Furthermore, it also includes a third stirring paddle 5; the third stirring paddle 5 includes a stirring cylinder 51 and a connecting rod 52; the stirring cylinder 52 is a hollow conical cylinder with open ends, and the connecting rod 51 connects the stirring cylinder 52 to the fixed plate 2 and / or the second stirring paddle 4.

[0051] Furthermore, there are three third stirring paddles 5, which are evenly distributed at one end of the fixed plate 2 away from or near the stirring shaft 1, and the included angle between adjacent connecting rods 52 is 120°.

[0052] Furthermore, there are two third stirring paddles 5, which are located on the front and rear sides of the fixed plate 2 respectively and are connected to the end of the fixed plate 2 away from the stirring shaft 1; or the two third stirring paddles 5 are connected to the two sides of the second stirring paddle 4 away from the fixed plate 2 respectively.

[0053] Furthermore, there are four third stirring paddles 5; two of the third stirring paddles 5 are located on the front and rear sides of the fixed plate 2 respectively, and are connected to the end of the fixed plate 2 away from the stirring shaft 1; the two third stirring paddles 5 are connected to the two sides of the second stirring paddle 4 away from the fixed plate 2 respectively.

[0054] Furthermore, the number of third stirring paddles 5 is five; wherein, three third stirring paddles 5 are evenly distributed at one end of the fixed plate 2 away from the stirring shaft 1 or three third stirring paddles 5 are evenly distributed at one end of the fixed plate 2 close to the stirring shaft 1; two third stirring paddles 5 are respectively connected to the two sides of the second stirring paddle 4 away from the fixed plate 2.

[0055] Furthermore, there are six third stirring paddles 5; three of the third stirring paddles 5 are evenly distributed at the end of the fixed plate 2 away from the stirring shaft 1; three of the third stirring paddles 5 are evenly distributed at the end of the fixed plate 2 close to the stirring shaft 1; and the third stirring paddles 5 at both ends of the stirring shaft 1 are staggered.

[0056] This implementation scheme, through the addition of a third agitator, increases the dimensionality of the mixing process. The even distribution of connecting rods and the special shape of the mixing drum create more flow patterns in the material during mixing, achieving multi-dimensional mixing, further breaking up material agglomeration, improving mixing effect and production efficiency, ensuring product quality, and simultaneously achieving better defoaming. In actual production applications, the number and distribution of the third agitator can be adjusted to adapt to different scales of rosin emulsion production.

[0057] Furthermore, the angle between the centerline of the stirring cylinder 52 and the length direction of the connecting rod 51 is 15~20°, and the diameter ratio of the first opening diameter to the second opening diameter of the stirring cylinder 52 is 5:3~4.

[0058] This implementation scheme optimizes the role of the mixing drum during the mixing process by improving the structure of the mixing drum and connecting rod. This results in a more rational flow of materials within the drum, forming unique vortices and flow paths, which helps improve the uniformity and efficiency of mixing, while also enhancing defoaming and ensuring the mixing effect of the rosin emulsion. Further structural constraints on the mixing drum allow for better flow and mixing of materials, preventing blockages and improving mixing efficiency and product quality, while also enhancing defoaming.
