Description

Technical Field

[0001] This utility model relates to the field of dispersion tank technology, and in particular to a high-speed dispersion tank. Background Technology

[0002] A high-speed dispersion vessel is a device used to uniformly disperse solid particles, liquids, or gases into a liquid medium. It is widely used in industries such as chemical, pharmaceutical, food, coating, ink, adhesive, and nanomaterials. Its core function is to fully disperse, mix, or emulsify different components through mechanical force to obtain a homogeneous mixture or dispersion.

[0003] The working principle of a dispersion vessel mainly relies on the shear force and fluid kinetic energy generated by the high-speed rotation of components such as dispersion blades and paddles, forming turbulence and eddies to achieve material dispersion and mixing. In common dispersion vessel designs, the dispersion blades and paddles often adopt a linear structure. The force generated by mechanical motion can only complete the material processing on a single horizontal plane, lacking effective coordination between the blades and paddles, making it difficult for the equipment to achieve a balance between the upward flow and lateral dispersion capabilities of the material.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1 and Figure 2 A high-speed dispersion vessel includes: a vessel body 1, a drive motor 2, a stirring shaft 3, a stirring rod 4, an arc-shaped blade 5, and a paddle 6;

[0025] The stirring shaft 3 and several stirring rods 4 are coaxially installed in the inner cavity of the vessel body 1. The stirring shaft 3 is rotatably connected to the vessel body 1 and one end of the stirring shaft 3 is connected to the drive motor 2. The stirring rod 4 includes a vertical part 41 and a connecting part 42 that connects the vertical part 41 and the stirring shaft 3. The vertical part 41 and the stirring shaft 3 maintain a predetermined distance.

[0026] The vertical section 41 has a vertical array of several arc-shaped blades 5 and several paddles 6 on its side wall. The center of the arc-shaped blades 5 coincides with the axis of the stirring shaft 3. The free end of the paddles 6 faces the stirring shaft 3. The height of the front end of the arc-shaped blades 5 and the paddles 6 is lower than the height of the rear end.

[0027] In actual use, after the material is put into the inner cavity of the vessel body 1, the drive motor 2 is started to drive the stirring shaft 3 to rotate. With the height of the first end of the arc-shaped blades 5 and the paddle 6 being lower than the height of the tail end, the bearing surfaces of the arc-shaped blades 5 and the paddle 6 will exert a vertical upward force on the material, thus causing the material to flow vertically upward. After the material flows over the bearing surfaces of the arc-shaped blades 5 and the paddle 6, the material falls down under its own gravity. Under the repeated stirring action of the arc-shaped blades 5 and the paddle 6, the material repeatedly flows up and down, thereby improving the material dispersion efficiency.

[0028] Furthermore, in this embodiment, during the operation of the dispersion vessel, a larger bearing surface is obtained by using the arc-shaped blade 5, which provides a larger upward guiding surface and force for the material, thereby improving the efficiency of material mixing and decomposition. While using the paddle 6 to further improve the guiding force for the upward flow of the material, the paddle 6 with a smaller bearing surface ensures the dispersion effect of the material and ensures the crushing effect of the material.

[0029] In this case, considering the difference in the bearing area of ​​the arc blade 5 and the blade 6, several arc blades 5 and blades 6 are arranged alternately in the vertical direction to ensure the uniformity of the stirring effect of the material in the vessel 1.

[0030] exist Figure 3 In the example shown, the arc-shaped blade 5 includes a first ring portion 51 and a second ring portion 52. The middle of the outer ring of the first ring portion 51 is connected to the vertical portion 41. The inner ring of the first ring portion 51 is fixedly sleeved on the outer ring of the second ring portion 52. When the bearing surface of the second ring portion 52 applies an upward force to the material, based on the inward inclined surface structure of the bearing surface of the second ring portion 52, an inclined force is applied to the material towards the stirring shaft 3. This guides the material to flow upward and also guides the material to flow towards the center of the inner cavity of the vessel body 1, thereby increasing the squeezing force between the materials and further increasing the mixing effect of the materials.

[0031] Meanwhile, a number of vertical through holes 53 are provided on the second ring 52, and the number of vertical through holes 53 are arranged in a circumferential array about the stirring shaft 3. This allows the material to flow downwards through the vertical through holes 53 during the flow of the material on the bearing surface of the second ring 52, thereby increasing the guiding direction of the material by the second ring 52 and improving the stirring effect of the material.

[0032] Meanwhile, in order to further enhance the tendency of the material to flow towards the center of the inner cavity of the vessel body 1, several arc-shaped blades 5 and several paddle blades 6 are set to connect to the side wall of the vertical part 41 facing the stirring shaft 3. The side wall of the vertical part 41 facing away from the stirring shaft 3 is connected to one side of the scraper 7, so that the other side wall of the scraper 7 is in contact with the inner wall of the vessel body 1.

[0033] As the stirring shaft 3 drives the stirring rod 4 to rotate synchronously, it drives the scraper 7 to brush against the inner wall of the vessel 1, separating the material from the inner wall of the vessel 1, and then squeezing the material to flow towards the center.

[0034] In addition, Figure 4 In the example shown, the scraper 7 includes a first connecting part 71 and a second connecting part 72. One side of the first connecting part 71 is connected to the outer ring sidewall of the vertical part 41, and the other side of the first connecting part 71 is connected to the second connecting part 72 and forms an acute angle with the second connecting part 72, so that the free end of the second connecting part 72 forms a predetermined angle with the inner wall of the vessel body 1. The free end of the second connecting part 72 faces the positive rotation direction of the stirring shaft 3, so that the material separated from the inner wall of the vessel body 1 first enters the groove formed by the second connecting part 72 and the first connecting part 71, thereby buffering the material flow and improving the smoothness of the material flow process.

[0035] Meanwhile, the free end of the second connecting part 72 is provided with a barb 73 on the side facing the opposite direction of the stirring shaft 3. After the material processing is completed, the stirring shaft 3 can be driven to drive the stirring rod 4 to rotate in the opposite direction. Due to the addition of the barb 73, the bearing surface of the barb 73 is smaller than that of the second connecting part 72, which is more suitable for fine processing, thereby improving the cleaning effect on the inner wall of the vessel 1.

[0036] 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.
