Mixing and dispersing materials in a vacuum pressure environment provides optimal results. However, machines using vacuum emulsifying pots or vacuum dispersers have drawbacks such as high purchase and maintenance costs, high energy consumption, and potential for malfunctions that could disrupt production.

[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A material mixing and dispersing device includes a mixing cylinder, a guide cylinder, an upper rotating component, and a lower rotating component. The mixing cylinder is in the shape of a through cylinder. The guide cylinder is disposed at the inner bottom of the mixing cylinder, and the opening of the guide cylinder is opposite to the opening of the mixing cylinder. An opening is formed on the outer circumferential surface of the bottom of the guide cylinder. The upper rotating component is installed at the top opening of the mixing cylinder, and an upper stirring blade is connected to the rotating end of the upper rotating component. The upper stirring blade is distributed on the outer side of the guide cylinder. The lower rotating component is installed at the bottom opening of the mixing cylinder, and a lower stirring blade is connected to the rotating end of the lower rotating component. The lower stirring blade is located inside the guide cylinder.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Terms such as “upper,” “inner,” “middle,” “left,” “right,” and “one” used in this specification are merely for clarity of description and are not intended to limit the scope of the present invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the present invention.
[0021] This invention addresses the shortcomings of existing vacuum mixing technologies. Because these technologies require specialized vacuum equipment and traditional mixing devices to achieve uniform mixing in a vacuum environment, they often suffer from high structural and maintenance costs, as well as high energy consumption. To address these issues, a material mixing and dispersing device has been designed that can achieve uniform dispersion and mixing of materials without the need for a separate vacuum device (vacuum emulsifying pot or vacuum disperser). Furthermore, this device boasts a simpler structure, effectively reducing costs and energy consumption.
[0022] The following is a detailed description of the structure and working principle of the material stirring and dispersing device of this utility model:
[0023] A material mixing and dispersing device, such as Figures 1 to 4 As shown, it includes a stirring cylinder 1, a guide cylinder 2, an upper rotating component 3, and a lower rotating component 4.
[0024] The mixing drum 1 is shaped like a through cylinder. The top opening of the mixing drum 1 is sealed with an upper cover 11 by a sealing ring, and the bottom opening of the mixing drum 1 is sealed with a lower cover 12 by a sealing ring, so that the inside of the mixing drum 1 is in a relatively sealed state. The upper cover 11 and the lower cover 12 can be installed by threaded connection, bolt connection, or other methods.
[0025] The guide cylinder 2 is fixedly connected to the inner bottom of the mixing cylinder 1, and the opening of the guide cylinder 2 is opposite to the opening of the mixing cylinder 1. Several openings 21 are provided on the outer circumferential surface of the bottom of the guide cylinder 2, and the several openings 21 are evenly distributed along the annular direction.
[0026] The upper rotating component 3 is a three-phase asynchronous motor. The upper rotating component 3 is installed on the upper cover 11. The rotating end of the upper rotating component 3 passes through the upper cover 11. The rotating end of the upper rotating component 3 is connected to the upper stirring blades, which are distributed on the outside of the guide cylinder 2.
[0027] The lower rotating component 4 is a three-phase asynchronous motor. The lower rotating component 4 is installed on the lower cover 12. The rotating end of the lower rotating component 4 passes through the lower cover 12. The rotating end of the lower rotating component 4 is connected to the lower stirring blade, which is located inside the guide cylinder 2.
[0028] Therefore, by adjusting the rotation speed of the upper rotating part 3 and the lower rotating part 4 to stir the material inside, the material can be fed upward into the guide cylinder 2 under the stirring action of the lower stirring blade. Then, through the stirring action of the upper stirring blade, the material in the guide cylinder 2 is dispersed from all sides and falls to the inner bottom surface of the mixing cylinder 1, and further enters the guide cylinder 2 through the opening 21, so as to realize the material is circulated and stirred and dispersed homogenized along the guiding direction. Moreover, it can eliminate the need for existing special vacuum devices, and has the advantages of simple structure and effective cost and energy consumption reduction.
[0029] In this embodiment, the operating speed of the upper rotating component 3 is lower than that of the lower rotating component 4. Therefore, the high-speed rotating lower stirring blades at the bottom generate suction during stirring, drawing the material from the bottom of the guide cylinder 2 upwards. The material at the top of the guide cylinder 2 disperses outwards under centrifugal force, and the low-speed upper stirring blades at the top exert downward pressure during stirring, along with the material's own gravity, thus creating a ring-like effect similar to a magnetic field within the stirring cylinder 1, effectively promoting the homogeneity of the material dispersion. Simultaneously, during operation, the speed of the high-speed lower rotating component 4 should be controlled to prevent excessive upward ejection of the material from the liquid surface, thus avoiding the formation of bubbles. Furthermore, the specific rotation speeds of the upper rotating component 3 and the lower rotating component 4 typically need to be flexibly adjusted and set based on the viscosity of the material and the total liquid level.
[0030] In this embodiment, a conical frame 22 is fixedly connected to the top of the guide cylinder 2, and a cone-shaped head 23 with its tip pointing downwards is fixedly connected to the top surface of the conical frame 22. Therefore, under the stirring action of the high-speed rotating upper component 3, when the material is drawn from the bottom to the top of the guide cylinder 2, the material will be buffered by the conical frame 22 and the cone-shaped head 23 with its tip pointing downwards, thereby causing the material to spread evenly in all directions, thus reducing the impact of the material on the upper cover 11, and improving the efficiency of the material stirring and dispersing.
[0031] In this embodiment, the upper stirring blade includes two stirring paddles 31 arranged on both sides of the guide cylinder. Several guide plates 32 are fixedly connected to the side of each stirring paddle 31 facing the other stirring paddle 31. The guide plates 32 are spaced apart along the length of the stirring paddle 31, and the inclination directions of the guide plates 32 on the same stirring paddle 31 are consistent. The two stirring paddles 31 are centrally symmetrical about the guide cylinder 2. Therefore, by defining the shape of the upper stirring blade, when the upper rotating member 3 rotates at low speed and generates downward pressure, the material will be thrown out in the same direction under the guiding effect of the inclination direction of the guide plates 32, thereby achieving the effect of uniform stirring or uniform dispersion.
[0032] At the same time, the two agitators 31 of the upper agitator blade extend downwards to a position close to the opening 21. Thus, when the material is pressed down by the upper agitator blade, it can be pressed down as close to the opening 21 as possible, thereby achieving thorough mixing and facilitating the entry of the pressed material into the guide cylinder 2 through the opening 21.
[0033] In this embodiment, the lower stirring blade includes a stirring shaft 41 and a stirring fan blade 42 disposed at the end of the stirring shaft 41. Thus, by setting the stirring fan blade 42, an upward force is generated to transport the material at the bottom of the guide cylinder 2 upward, thereby improving the stirring efficiency of the material.
[0034] In summary, this invention employs a low-speed-at-the-top and high-speed-at-the-bottom driving principle. Under the stirring action of the lower rotating component 4 at high speed at the bottom, the material at the bottom of the guide cylinder 2 is drawn upwards. As it leaves the top of the guide cylinder 2 and passes through the conical frame 22, the material disperses in all directions due to centrifugal force and the action of the conical frame 22. Then, under the stirring action of the upper rotating component 3 at low speed at the top, a downward force is generated. Simultaneously, under the guiding action of the guide plate 32, the material is evenly scattered and distributed at the bottom of the mixing cylinder 1, and then enters the guide cylinder 2 through the opening 21. This allows the material to achieve a circular circulation motion. Furthermore, it can achieve uniform stirring and dispersion of the material without the need for a vacuum device, and can effectively control costs and reduce energy consumption.
[0035] The embodiments of this utility model are not limited thereto. Based on the above content of this utility model, using ordinary technical knowledge and conventional means in the field, without departing from the basic technical idea of this utility model, this utility model can also be modified, replaced or combined in various other forms, all of which fall within the scope of protection of this utility model.
