Description

Technical Field

[0001] This utility model belongs to the technical field of material dispersion equipment, and is particularly suitable for a double-blade disperser that optimizes the dispersion effect. Background Technology

[0002] In daily life, dispersers are often needed when mixing and dispersing coatings, dyes, inks, pigments, and cosmetics. Traditional double-blade dispersers typically employ a coaxial double-layer dispersion disc structure, relying on the shear force generated by high-speed rotation to disperse materials. However, existing technology has the following problems: 1. Uneven dispersion: The co-rotation of the upper and lower dispersion discs results in a single material flow direction, easily forming eddies and leading to insufficient dispersion in local areas; 2. Poor adaptability: The fixed spacing between the dispersion discs makes it difficult to adjust the shear intensity according to the material viscosity. Utility Model Content

[0003] The purpose of this invention is to provide a double-blade disperser with optimized dispersion effect. Through the asymmetric dispersion disc design and adjustable spacing structure, it optimizes the material convection path, enhances shear force, and improves dispersion efficiency and adaptability, making it especially suitable for production processes that require mixing various materials.

[0004] The technical solution of this utility model is: a double-blade disperser for optimizing dispersion effect, comprising a barrel, a drive motor, a rotating shaft, an upper dispersing component, a conical guide shroud, and a lower dispersing disc. The upper end of the barrel is provided with a placement plate, and the placement plate is provided with the drive motor. The output shaft of the drive motor passes through a drive hole in the placement plate and is connected to the rotating shaft. The rotating shaft is provided with an upper threaded adjustment section and a lower threaded adjustment section. The upper dispersing component includes an upper dispersing disc and upper dispersing blades. The upper dispersing disc has an upper through hole in the middle, and the upper dispersing disc is sleeved on the rotating shaft through the upper through hole. A first upper nut and a second upper nut are respectively located above and below the upper dispersing disc and are threadedly connected to the upper threaded adjustment section. Multiple upper dispersing blades are provided along the circumference of the upper dispersing disc. The conical guide shroud is located on the rotating shaft and between the upper threaded adjustment section and the lower threaded adjustment section.

[0005] The lower dispersion disc component includes a lower dispersion disc and lower dispersion blades. The lower dispersion disc has a lower through hole in the middle and is sleeved on the rotating shaft through the lower through hole. The first lower nut and the second lower nut are respectively located above and below the lower dispersion disc and are threadedly connected to the lower threaded adjustment section. The lower dispersion disc has multiple lower dispersion blades along its circumference. The inclination direction between the upper dispersion blades and the upper dispersion disc is opposite to the inclination direction between the lower dispersion blades and the lower dispersion disc. The side wall of the machine barrel has a cooling cavity, and the cooling cavity has a cooling pipe. The side wall of the machine barrel has a cooling pipe inlet and a cooling pipe outlet.

[0006] Preferably, the plurality of upper dispersing blades of the upper dispersing disk are arranged at a clockwise inclination of 45°, and the plurality of lower dispersing blades of the lower dispersing disk are arranged at a counterclockwise inclination of 45°.

[0007] Preferably, the diameter of the lower dispersing disk is larger than that of the upper dispersing disk.

[0008] Preferably, the surface of the conical flow guide is uniformly distributed with flow guide holes.

[0009] The advantages and positive effects of this utility model are as follows: Due to the adoption of the above technical solution, the inclination direction between the upper dispersing blade and the upper dispersing disk is opposite to the inclination direction between the lower dispersing blade and the lower dispersing disk, which can generate multi-directional shear force, break the eddy current, and improve the dispersion uniformity. The setting of the upper threaded adjustment section and the lower threaded adjustment section can adjust the distance between the upper dispersing disk and the lower dispersing disk, adapt to materials of different viscosities, and expand the application range. The conical guide shroud can promote material circulation, reduce blind spots, and the cooling pipe prevents material denaturation caused by high temperature. Attached Figure Description

[0017] like Figure 1As shown, the technical solution of this utility model is a double-blade disperser with optimized dispersion effect, including a barrel 1, a drive motor 2, a rotating shaft 3, an upper dispersing component, a conical guide shroud 4, and a lower dispersing disc. The barrel 1 has a placement plate 5 at its upper end, and the drive motor 2 is mounted on the placement plate 5. The output shaft of the drive motor 2 passes through a drive hole on the placement plate 5 and is connected to the rotating shaft 3. The rotating shaft 3 has an upper threaded adjustment section and a lower threaded adjustment section. The upper dispersing component includes an upper dispersing disc 6 and upper dispersing blades 7. The upper dispersing disc 6 has an upper through hole in its middle position, and the upper dispersing disc 6 is sleeved on the rotating shaft 3 through the upper through hole. A first upper nut and a second upper nut 8 are respectively located above and below the upper dispersing disc 6 and are threadedly connected to the upper threaded adjustment section. Multiple upper dispersing blades 7 are arranged along the circumference of the upper dispersing disc 6. The conical guide shroud 4 is located on the rotating shaft 3 and between the upper threaded adjustment section and the lower threaded adjustment section.

[0018] The lower dispersion disc component includes a lower dispersion disc 9 and lower dispersion blades 10. The lower dispersion disc 9 has a through hole in its center, through which it is sleeved onto the rotating shaft 3. A first lower nut and a second lower nut 11 are respectively located above and below the lower dispersion disc 9 and are threadedly connected to the lower threaded adjustment section. Multiple lower dispersion blades 10 are arranged along the circumference of the lower dispersion disc 9.

[0019] The side wall of the machine barrel 1 is provided with a cooling cavity 12, and a cooling pipe 13 is provided inside the cooling cavity 12. The side wall of the machine barrel 1 is provided with a cooling pipe inlet and a cooling pipe outlet, which facilitates the introduction of condensate water and prevents the material from denaturing due to high temperature.

The two form a reverse shearing force, which improves the dispersing efficiency.

[0021] In this embodiment, the diameter of the lower dispersing disk 9 is larger than that of the upper dispersing disk 6, thereby expanding the bottom processing area.

[0022] In this embodiment, the surface of the conical guide shroud 4 is uniformly distributed with guide holes to guide the material to diffuse in all directions and circulate to the dispersion area.

[0023] The working process of this example is as follows: the distance between the upper and lower dispersion discs is adjusted according to the viscosity of the material to be dispersed, the material is then poured into the drum, condensate is introduced into the cooling pipe inlet, the drive motor is turned on, and multiple upper and lower dispersion blades stir and disperse the material. The conical guide shroud guides the material to diffuse in all directions and circulate to the dispersion area to make the dispersion more complete.
