Abstract
The universal mixer is comprised of a revolution container body (1), preferably cylindrical and capable of rotating during the mixing phase, and characterized in that its revolution shaft (7) integral with the container body (1) adopts a substantially skewed position with respect to the geometrical axis of said body, specifically traversing its bases at marginal and diametrally opposite points.
There is provided at one of said bases (3), and opposite to the shaft (7), a filling-emptying mouth (4) closeable by means of a sealed closure lid (5), so that said mouth or opening is susceptible of adopting an upper extreme position for filling the mixer and a lower extreme position for emptying the mixer after homogenization of the mixture. Inside the container (1) are provided blades (11) which may rotate in conjunction with said container or which may be displaced independently in order to improve the removal of the mixture, the blades being optionally provided with cutting edges so as to have a complementary cutting effect.

Claims
C L A I M S
1. A universal mixer of the type which incorporates a container body (1), able to receive the materials to be mixed and able also to receive a rotary movement determining the mixing operation inside it, wherein, essentially, said container body (1) is rigidly joined to a shaft (7) which adopts a markedly skewed position with respect to the geometrical axis of said body (1) such that the rotary movement of said shaft (7), and consequently of the tank (1), gives rise to an alternating longitudinal displacement of the mass within said container body (1).
2. The universal mixer as claimed in claim 1, wherein the shaft (7) adopts a horizontal position, resting on end supports (8) by means of bearings or any other suitable antifriction means.
3. The universal mixer as claimed in the preceding claims, wherein the container body (1) incorporates, in one of its end bases (3), or in the zone close to its lateral surface, a filling/emptying mouth (4) which, as a function of the oblique position of the shaft (7), is capable of adopting both a position of maximum elevation in the context of the mixer and a lower limit position.
4. The universal mixer as claimed in claim 3, wherein said filling/emptying mouth (4) is assisted by a sealed closure lid (5).
5. The universal mixer as claimed in the preceding claims, wherein the container body (l) has a cylindrical configuration and the shaft (7), to which it is rigidly joined, traverses one of its bases (3) in a limit position opposite the filling/emptying mouth (4) while it traverses its other base (2), also marginally and opposite the first one.
5. The universal mixer as claimed in the preceding claims, wherein the mixing chamber defined within the container body contains stirring blades (9) which may be, without distinction, fastened to the shaft (7) and/or to the actual container body (1).
7. The universal mixer as claimed in the preceding claims, wherein the blades for stirring the product accommodated inside the container body (1) have the form of at least one screw propeller (11) appropriately secured to the rotary shaft (7) of said container (1), with the special feature that said screw propellers define pairs of blades (11) of opposing pitch, it being possible for said pairs of opposing pitch to be located on the same screw propeller or on different screw propellers.
8. The universal mixer as claimed in claim 1 to 5, wherein the interior of the container body contains stirring blades (11) on a shaft (14), which is independent of the rotary shaft (7) of the container, so that said blades (11) receive movement from a drive element (13) which is also independent of the drive element (12) of the container body (1).
9. The universal mixer as claimed in claim 8, wherein the complementary shaft (14), belonging to the blades (11), is tubular and is mounted axially, by means of bearings or the like, on the main shaft (7) for actuating the container body (1).
10. The universal mixer as claimed in claim 1 to 6, wherein the interior of the container body (1) contains stirring blades (15) provided with sharpened edges which, in parallel with its stirring function, confer on it a cutting effect, it being possib1e for said blades to have the form of real cutting knives (15).
1. A universal mixer of the type which incorporates a container body (1), able to receive the materials to be mixed and able also to receive a rotary movement determining the mixing operation inside it, wherein, essentially, said container body (1) is rigidly joined to a shaft (7) which adopts a markedly skewed position with respect to the geometrical axis of said body (1) such that the rotary movement of said shaft (7), and consequently of the tank (1), gives rise to an alternating longitudinal displacement of the mass within said container body (1).
2. The universal mixer as claimed in claim 1, wherein the shaft (7) adopts a horizontal position, resting on end supports (8) by means of bearings or any other suitable antifriction means.
3. The universal mixer as claimed in the preceding claims, wherein the container body (1) incorporates, in one of its end bases (3), or in the zone close to its lateral surface, a filling/emptying mouth (4) which, as a function of the oblique position of the shaft (7), is capable of adopting both a position of maximum elevation in the context of the mixer and a lower limit position.
4. The universal mixer as claimed in claim 3, wherein said filling/emptying mouth (4) is assisted by a sealed closure lid (5).
5. The universal mixer as claimed in the preceding claims, wherein the container body (l) has a cylindrical configuration and the shaft (7), to which it is rigidly joined, traverses one of its bases (3) in a limit position opposite the filling/emptying mouth (4) while it traverses its other base (2), also marginally and opposite the first one.
5. The universal mixer as claimed in the preceding claims, wherein the mixing chamber defined within the container body contains stirring blades (9) which may be, without distinction, fastened to the shaft (7) and/or to the actual container body (1).
7. The universal mixer as claimed in the preceding claims, wherein the blades for stirring the product accommodated inside the container body (1) have the form of at least one screw propeller (11) appropriately secured to the rotary shaft (7) of said container (1), with the special feature that said screw propellers define pairs of blades (11) of opposing pitch, it being possible for said pairs of opposing pitch to be located on the same screw propeller or on different screw propellers.
8. The universal mixer as claimed in claim 1 to 5, wherein the interior of the container body contains stirring blades (11) on a shaft (14), which is independent of the rotary shaft (7) of the container, so that said blades (11) receive movement from a drive element (13) which is also independent of the drive element (12) of the container body (1).
9. The universal mixer as claimed in claim 8, wherein the complementary shaft (14), belonging to the blades (11), is tubular and is mounted axially, by means of bearings or the like, on the main shaft (7) for actuating the container body (1).
10. The universal mixer as claimed in claim 1 to 6, wherein the interior of the container body (1) contains stirring blades (15) provided with sharpened edges which, in parallel with its stirring function, confer on it a cutting effect, it being possib1e for said blades to have the form of real cutting knives (15).
