Vessel and mixer

Abstract

This invention is directed toward a mixing vessel and mixer where the design of the mixer and mixing vessel allow the mixer to reach all the cracks and crevices of the mixing vessel. The mixer also has two opposing openings with mixing vanes that facilitate turbulence and blending through a strong centrifugal flow. The mixer has unbroken or minimally broken surfaces for grinding/shearing lumps into a smooth, lump-free paste.

DETAILED DESCRIPTION OF THE FIGURES

[0034] Many aspects of the invention can be better understood with references made to the drawings below. The components in the drawings are not necessarily drawn to scale. Instead, emphasis is placed upon clearly illustrating the components of the present invention. Moreover, like reference numerals designate corresponding parts through the several views in the drawings. Before explaining at least one embodiment of the invention, it is to be understood that the embodiments of the invention are not limited in their application to the details of construction and to the arrangement of the components set forth in the following description or illustrated in the drawings. The embodiments of the invention are capable of being practiced and carried out in various ways. In addition, the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.

[0035] FIG. 1 is a perspective view of the mixing vessel and mixer. The mixing vessel, referred to generally as 1 is a long, racetrack-shaped container with a sloped side 6 and end sections 5 that are shaped like semi-circles. This allows the round mixer to mate with both the sides 4 and ends 5 of the mixing vessel, thereby removing the pockets found in the prior art which prevented effective mixing. Because the sides 4 of the vessel are higher than the mixer 2, there is not a problem with the mixer causing material to back up and spill over the sides 4 or ends 5 of the mixing vessel. There are two opposing openings 13 in the mixer which include mixing vanes 12 and 14 which facilitate turbulence for liquid mixing and for the initial blending of liquid and powder (and/or paste). The mixing vanes have both a leading angle and a following angle which serve to thoroughly mix either a powder/liquid or powder/paste combination, or to stir a viscous liquid such as paint. The mixer has two opposing unbroken or minimally broken surfaces 17 and bottom for grinding/shearing lumps into a smooth, lump-free paste.

[0036] FIG. 2 is a top view of the mixing vessel and mixer. The vessel has a vessel width 10, which is greater than the mixer width 11, such that as the mixer is being moved back and forth along the mixing vessel, the liquid and or paste can move around either side of the mixer, such that there is no problem with the mixer forcing a backup of material over and outside the sides 4 or ends 5 of the vessel.

[0037] FIG. 3 is a side view of the mixing vessel and mixer. This figure shows that the vessel height 8 is larger than the height of the mixer, which is obscured by the sides of the vessel other than the stem 3 of the mixer. Therefore, as the mixer is being moved forward and back through the vessel, any liquid can flow either around or over the mixer, thereby preventing any problems with spillage. This view also shows the sloped sides 6 of the vessel. The angle of the slope mates with the angle of the mixer (7 in FIG. 4).

[0038] FIG. 4 is cross sectional view of the mixer in the mixing vessel, showing how the mixer has a lower height than the mixing vessel and how the edges of the mixer mate with the inner edges of the mixing vessel. The mixer height 9 is less than the vessel height 8, such that liquid can flow over the mixer to avoid backup and spillage problems. The mixer 2 has a smaller width than does the vessel 1, so that liquid can move around the sides of the mixer to avoid the same overflow and spillage problems. The mixer side angle 7 is the same angle as the vessel side angle 6. The stem 3 is attached to the bottom of the mixer.

[0039] FIG. 5 is a perspective view of the mixer, showing its basic components. A stem 3 is used to connect the mixer to any standard electric drill. At opposing sides of the mixer are two openings 13. Having the two openings 13 directly opposite each other allows for reverse operations for faster mixing/blending. Each opening has a mixing vane, generally described by 12 and 14, with a mixing vane leading edge and a mixing van trailing edge respectively. The opening 13 allows the liquid and the powder to interact with the mixing vanes by creating strong centrifugal flow down through the mixer head when it is fully submerged. The opening 13 also facilitates liquid mixing and initial powder/liquid blending by forcing these substances to interact with the mixing vanes 12. The mixer has a complete top ring 18, which serves to not only solidify and strengthen the mixer, and two anti-chatter projections 15. Both top ring and projections serve to reduce chatter, vibration, and splatter.

[0040] The mixing vane 12 facilitates turbulence for liquid mixing and initial powder, paste, and liquid blending. The mixing vane angle 16 initiates centrifugal flow through the mixer and creates turbulence. It also facilitates the mixing of powder/liquid combinations as it drives material down into the vessel.

[0041] The mixing vane following angle 14 assists with liquid mixing as it creates turbulence in the flow of material, and removes material from inside the mixer, thereby assisting with blending the material thoroughly.

[0042] At opposing sides of the mixer are unbroken or minimally broken surfaces 17. Each surface 17 and mixer bottom allows the liquid and powder or paste with dry lumps to be ground and sheared thus incorporated into a smooth lump free paste. As mixer is moved around vessel both centrifugal and rotational forces draw the liquid, powder and paste into the grinding/shear zones. Paste clings to outside of mixer thus drawing more into grinding/shear zones. It is well known in the industry that when a dry, fine material is mixed with a liquid such as water, the dry material becomes coated with an outside layer of moist material and is nearly impossible to break up using only a stirring action. Thus, these lumps must be either cut or ground into smaller and smaller pieces such that they eventually become the desired end product. The prior art does not provide us with a reasonable way in which these lumps can be ground into the final paste, but the current invention does so due to its novel configuration. The current invention provides an unbroken surface at the bottom and sides of the mixer, which interact against a stationary surface. This will draw in and break up, through shearing and grinding, lumps and incorporate them into the final, desired end slurry or paste. The centrifugal force created by the vanes and openings creates mixing channels that ensure that any lumps are eventually forced through all of the various mixing, grinding and shearing components of the invention.

[0043] FIG. 6 is a side view of the mixer with one of its openings facing the viewer. The opening 13 is opposite an opening on the other side of the stem 3. The mixing vanes are symmetrical on each side of the opening, such that the mixer is balanced and can be run in reverse. The mixing vane angle 16, described in FIG. 5, is apparent here.

[0044] FIG. 7 is a side view of the mixer turned 90 degrees from the figure in FIG. 6, showing a side view of the openings 13 as well as the anti-chatter projection and mixer top ring, 15 and 18 respectively.

[0045] FIG. 8 is a bottom view of the mixer. This figure shows the mixing vane leading angle 12 and the mixing vane following angle 14. This figure also shows below each opening the anti-chatter projection 15, which maintains a near continuous bottom diameter and the mixer bottom 20.

[0046] FIG. 9 is a top view of the mixer.

[0047] FIG. 10 is a cross-sectional view of the mixer.

[0048] FIG. 11 is a view of the mixer with the shaft extension 19 installed on the mixer. The shaft extension permits mixer to reach the bottom of deep containers.

[0049] It should be understood that while the preferred embodiments of the invention are described in some detail herein, the present disclosure is made by way of example only and that variations and changes thereto are possible without departing from the subject matter coming within the scope of the following claims, and a reasonable equivalency thereof, which claims I regard as my invention.
