Description

BACKGROUND OF THE INVENTION

This invention relates to paddle mixers of particulate substances with liquids and in particular to paddles having mixing blades oriented to compress the particulate substances and liquids together for dissolving and diffusing lumps, unmixed accumulations and bubbles.

Paddle mixers are well known historically. A wide variety have been devised for mixing various types and forms of particulate substances with various types and forms of liquids. None are known, however, to have compression paddles that are oriented for application of compressively mixing force on the particulate substances and the liquids to dissolve and to diffuse lumps and inadequately mixed accumulations or bubbles in a manner taught by this invention.

It is quite common knowledge that lumps and globs of inadequately mixed particulate substances in mixtures with liquids can be squeezed compressively to cause them to dissolve, diffuse and disintegrate into a mix. Regardless, however, paddle mixers and barrel mixers alike continue to rely on primarily agitative action that does not squeeze or compress the particulate substances and liquids. Consequently still required for conventional mixing are (1) pre-mix of particulate substances that are likely to lump and (2) gradual addition of liquid to particulate substances during mixing action. This invention eliminates both of these conventional mixing steps for mixing most particulate substances and liquids.

Examples of most-closely related known but different devices are described in the following patent documents:

Referring to FIGS. 1-4 , a compression-paddle mixer has a compression paddle 1 with one or more sets 2 of two paddle blades 3 on paddle spokes 4 that are extended radially from a paddle rod 5. The paddle blades 3 are juxtaposed colinearly to the paddle rod 5 and to each other.

Referring to FIGS. 1-6 , the paddle-rod 5 has a direction of rotation that is transmitted from a predetermined power source 6 that can include an engine, a motor or a hand crank which can be anchored to a small mix container 7, a large mix container 8 or can be hand-held separately for mixing particulate substances, liquids or combinations of particulate substances and liquids. The one or more sets 2 of two paddle blades 3 have circumferential travel in a direction that is transmitted through the paddle spokes 4 by the rotation of the paddle rod 5.

The sets 2 of the two paddle blades 3 have channel-funneled orientations in the direction of the circumferential travel of the sets 2. The channel-funneled orientations include channel-funnel inlets 9 having funnel-inlet areas intermediate leading edges of the paddle blades 3 of the sets 2 in the direction of the circumferential travel of the sets 2 that is indicated by direction-arrow arc 10. The channel-funneled orientations include channel-funnel outlets 11 having funnel-outlet areas intermediate trailing edges of the paddle blades 3 of the sets 2. The funnel-inlet areas are predeterminedly larger than the funnel-outlet areas.

Referring to FIGS. 1-8 , The channel-funneled orientations have compression ratios that are defined by ratios of the channel-funnel inlet areas to the channel-funnel outlet areas of the one or more sets 2 of the two paddle blades 3. The compression ratios are generally higher predeterminedly for mixes having high liquidity than for mixes having low liquidity relatively.

The rotation of the paddle rod 5 has a speed of rotation that is higher predeterminedly for mixes having the high liquidity than for the mixes having the low liquidity.

The compression paddle 1 has size, shape and structure articulated for predetermined quantities of mix that can range from one-to-pluralities of barrels for the large mix container 8 to one-to-pluralities of pints of the small mix container 7.

The mix containers ranging from the small mix container 7 to the large mix container 8 have a cylindrical interior periphery for a predetermined quantitative capacity of a plurality of select quantitative units ranging from pints to barrels. The compression paddle 1 has a paddle radius defined by a longest extremity of the compression paddle 1 from a center of the paddle rod 5 for articulation of the compression paddle 1 to fit and to rotate predeterminedly within the cylindrical interior of the intended small mix container 7 or the intended large mix container 8 designedly. The paddle blades 3 have lengths that proximate the length of the cylindrical interior periphery of the intended small mix container 7 or the intended large mix container 8.

The compression paddle 1, the small mix container 7 and the large mix container 8 have structure that is articulated for mixing predetermined consistencies of mix.

For articulation of the compression paddle 1, the small mix container 7 and the large mix container 8 selectively for production-item mixing, the predetermined consistencies of mix include particulate substances having construction-item consistencies of gravel, sand, cement, mortar, clay, alkalines and metallic particles selectively. Liquids for the production-item mixing include liquids having consistencies of water, liquidity modifiers, acid and petrochemicals selectively.

For articulation of the compression paddle 1, the small mix container 7 and the large mix container 8 selectively for non-production-item mixing, the predetermined consistencies of mix include non-production-item consistencies of flour, sugar, food particles, dyes and seasoning selectively. Liquids for the non-production-item consistencies of mix can include water, liquid food substances, honey, coloring, alcohol and preservatives selectively.

For most uses, the paddle blades 3 preferably, but not necessarily, have lengths which are predeterminedly longer than two radii of the compression paddle 1.

The paddle blades 3 have blade edges and blade thicknesses structured for ease of insertion into and removal from predetermined mix in the small mix container 7 and the large mix container 8 selectively. The paddle rod 5 has a rod insertion end 12 and rod thickness structured for ease of insertion into and removal from the predetermined mix. The paddle spokes 4 have thicknesses and structure articulated for ease of insertion into, rotation in and removal from the predetermined mix.

The paddle rod 4 has a rod-power end with a power-source connection 13 that is articulated for rotation-transmissive connection of the paddle rod 4 to the predetermined power source 6.

The small mix container 7 and the large mix container 8 can include a container bottom 14 that is flat and orthogonal to an axis of the paddle rod 4. Preferably the paddle blades 3 have blade bottoms 15 that travel circumferentially in predetermined proximity to the container bottom 14.

As shown for the large mix container 8 in FIGS. 7-8 , the container bottom 14 can include a valved opening 16. Optionally for the valved opening 16, the container bottom 14 includes a riser 17 with which the container bottom 14 is raised predeterminedly above a container-support surface 18 for allowing exit of the mix.

The one or more sets 2 of the paddle blades 3 can include two sets 2 as shown in FIGS. 1-6 or more as depicted by six sets 2 in FIGS. 7-9 .

Referring to FIGS. 1-9 , mix accumulations 19, which can include lumps, are depicted in FIG. 9 as being mixed, broken up, disintegrated, dissolved and diffused variously for different mix consistencies by the channel-funneled orientations of the sets 2 of the paddle blades 3 from rotation of the paddle rod 5 in the direction of circumferential travel indicated by the direction-arrow arc 10. The mix accumulations 19 are forced into the channel-funnel inlets 9 and funnel-compressed in directions of the channel-funnel outlets 11 by force of the circumferential travel of the sets 2 against resistance of mix 20 and against resistance of other mix accumulations 19. Released from the mix accumulations 19 at the channel-funnel outlets 11 are selections of consistencies of accumulation discharge 21 represented by illustrations of selections of fineness and shape.

This compression-paddle mixer provides not only improved agitative mixing but also eliminates conventional mixing steps of (1) pre-mix of particulate substances that are likely to lump and (2) gradual addition of liquid to particulate substances during mixing action with the compression paddle 1 in optional working relationship with the small mix container 7 and the large mix container 8 as described and claimed.

A new and useful compression-paddle mixer having been described, all such foreseeable modifications, adaptations, substitutions of equivalents, mathematical possibilities of combinations of parts, pluralities of parts, applications and forms thereof as described by the following claims and not precluded by prior art are included in this invention.
