Description

Technical Field

[0001] The utility model relates to the field of dispersion discs, in particular to a paint dispersion disc. Background Art

[0002] A disperser is broadly defined as a type of mixer. High-speed agitators (such as disc-shaped sawtooth agitators) can create strong localized turbulence, often resulting in a strong dispersing and emulsifying effect on materials. Therefore, these high-speed agitators are also called dispersers. Paint dispersers play a key role in mixing, dissolving, dispersing, and refining materials such as paints, dyes, and inks. Paint production typically involves adding powdered materials to a container in a specific proportion, stirring them, and applying specific processing techniques to create the desired coating.

[0003] Current dispersion disc designs on the market have several drawbacks. For example, the upper and lower dispersion teeth are integrated into the disc body, resulting in high costs when the teeth are damaged. Furthermore, when existing dispersion discs rotate at high speed to disperse the slurry, centrifugal force causes the slurry to move toward the barrel wall, resulting in poor dispersion uniformity.

[0004] CN210674839U discloses a dispersion disk and a stirring device having the same, comprising: a disk body, the disk body being provided with a guide hole penetrating the disk body and capable of guiding a fluid to flow axially along the disk body; and a serrated blade provided on the disk body. The above patent enhances the axial flow and mixing of the slurry through the guide hole, changes the flow pattern of the slurry's stirring and dispersion, reduces the formation of a central vortex, thereby expanding the effective volume, enhancing the dispersion effect, and improving the slurry mixing efficiency. However, the guide hole in the above patent is a through hole designed in a protrusion on the upper end surface of the disk body. In actual dispersion work, the flow disturbance effect of the guide hole provided on the upper end surface of the disk body is not significant, and there is a risk of splashing when the slurry is separated. In addition, slurry will accumulate in the guide hole.

[0005] Based on this, the technical problem solved in this case is: how to solve the problem of poor dispersion uniformity of slurry caused by centrifugal force. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a paint dispersion disk, which changes the flow of the slurry during stirring by arranging multiple disturbing bodies on the lower end surface, increases turbulence to the stable laminar flow, and improves the uniformity of dispersion. In addition, through the split design, the lower disk body can be replaced according to the product characteristics.

[0007] The technical solution of the utility model is:

[0008] A paint dispersion tray comprises an upper tray and a lower tray, wherein the upper tray and the lower tray are detachably connected and the rotation axis of the upper tray coincides with the rotation axis of the lower tray; a plurality of turbulent bodies are provided on the lower end surface of the lower tray; the plurality of turbulent bodies are arranged in a circular array around the rotation axis.

[0012] In the above-mentioned paint dispersion tray, the radius of the upper tray body is the same as the radius of the lower tray body.

[0013] In the above-mentioned paint dispersing disc, the upper serrations and the lower serrations are alternately arranged in the circumferential direction.

[0023] Upper plate body 1; lower plate body 2; disturbing body 3; thrust tooth 4; upper serration 101; lower serration 201; first connecting hole 110; center hole 120; second connecting hole 130. DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] See also Figure 1 、 2 A paint dispersion plate comprises an upper plate body 1 and a lower plate body 2, wherein the upper plate body 1 and the lower plate body 2 are detachably connected and the rotation axis of the upper plate body 1 coincides with the rotation axis of the lower plate body 2; a plurality of turbulent bodies 3 are provided on the lower end surface of the lower plate body 2; the plurality of turbulent bodies 3 are arranged in a circular array around the rotation axis.

[0027] When the dispersion disk of this embodiment is rotating at high speed to disperse the slurry, a plurality of turbulent bodies 3 are provided on the lower end surface, thereby changing the flow of the slurry during stirring, increasing turbulence to the stable laminar flow, and improving the uniformity of dispersion. In addition, the split design allows the lower disk body 2 to be replaced according to product characteristics.

[0028] As a preference of this embodiment, the disrupting body 3 is made into a hemispherical shape by stamping the lower disc 2 .

[0029] Of course, in other embodiments, in order to cater to the physical properties of the slurry, the structure of the disturbing body 3 can be further optimized, for example, a water drop shape, an ellipsoid, etc. can change the structure of the laminar flow.

[0030] In this embodiment, preferably, a plurality of thrust teeth 4 are provided on the outer edge of the upper disk body 1; and the plurality of thrust teeth 4 are arranged in a circular array around the rotation axis.

[0031] In this embodiment, it is further preferred that the thrust teeth 4 are arranged to be tilted downward. When the slurry is dispersed by high-speed rotation, the thrust teeth 4 will generate thrust on the slurry. Under the action of the thrust, an upward component of force is generated when the material hits the barrel wall, thereby lifting the slurry at the bottom of the barrel, realizing continuous vertical circulation, and making the slurry dispersion more efficient.

[0032] In this embodiment, specifically, the upper disk body 1 is provided with 12 upper serrations 101 ; the upper serrations 101 extend upward; and the 12 upper serrations 101 are arranged in a circular array around the rotation axis.

[0033] In this embodiment, more specifically, the lower disc body 2 is provided with 12 lower saw teeth 201; the lower saw teeth 201 extend downward; and the 12 lower saw teeth 201 are arranged in a circular array around the rotation axis.

[0034] In this embodiment, more specifically, the radius of the upper plate 1 is the same as the radius of the lower plate 2 .

[0035] In this embodiment, more specifically, the upper saw teeth 101 and the lower saw teeth 201 are alternately arranged in the circumferential direction.

[0036] The above-mentioned specific design in this embodiment is a relatively common arrangement in this field, all of which are for shearing the slurry to achieve dispersion. The difference from the conventional design is that in order to provide better circumferential stirring uniformity, the lower saw teeth 201 are arranged directly below the thrust teeth 4, and then alternately arranged circumferentially with the upper saw teeth 101. Under this design, the slurry at the bottom will first be lifted vertically by the lower saw teeth 201 and then by the thrust teeth 4, thereby achieving better circulation. Of course, the upper saw teeth 101 also play an important shearing role in the process.

[0037] As a preferred feature of this embodiment, both the upper and lower plates 1 and 2 are provided with first connection holes 110. There are at least three first connection holes 110 arranged in a circular array around the rotation axis. The upper and lower plates 1 and 2 are detachably connected via the first connection holes 110. In this embodiment, the first connection holes 110 are threaded holes, and the direction of the threads is opposite to the direction of rotation. With this design, the upper and lower plates 1 and 2 are detachably connected via bolts, and accidental separation of the upper and lower plates 1 and 2 is prevented.

[0038] In this embodiment, the upper plate 1 and the lower plate 2 are both provided with a central hole 120 for externally connecting the rotating shaft and a second connecting hole 130. This design is commonly used by those skilled in the art and will not be further explained in this embodiment.

[0039] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
