Definitions

  • the present invention refers to a mixer device, specially designed for the removal of different granular, powdery and/or liquid products, with the purpose of obtaining an homogeneous mixture thereof.
  • the object of the invention is to obtain the mentioned condition of homogeneous mixture, with a minimum consumption of energy and in a considerably short removal time, that is a high yield.
  • the mixer which is proposed is usable both at industrial level as well as private one, in any field in which it is required a mixture of two or more substances.
  • the mixers known up to the present have as common denominator the incorporation of a revolution body, capable of rotating on its own geometrical axis, in such a way that the removal of the materials to be mixed is produced by means of a combination of the movement itself of the rotating body, of the centrifugal force generated in such rotating movement, and of the force of gravity, being generally located the mentioned rotation axle in an inclined position in reference to the earth vertical axis.
  • a series of additional paddles facilitate the rising pulling of the material.
  • the universal mixer that the invention proposes has been designed precisely to have access to this third dimension, that is in order to achieve a complete removal, in correspondence with the three axis of a Cartesian coordinates system, which and as it is mentioned above, determines that the homogenization of the mixture is achieved in a considerable shorter time and, consequently, with a better energy consumption, which supposes a considerable increase of productivity and also a considerable costs reduction, compared with the conventional mixers.
  • the mixer which is recommended has, as main characteristic, the fact that its containing body is provided with a rotation axle in such a way that forms an acute angle with its geometrical axis, so that in the classic rotating movement of the containing body, it is also achieved the longitudinal vasculating movement which determines an alternative axial displacement for the mass, obviously complementary of the classic vertical and transversal displacements.
  • the mentioned containing body either in one of its external walls, or in its lateral wall area near to the one of such external walls, will incorporate the corresponding opening for filling/emptying, that in this case and due to the special mobility of the containing body should be supported by a hermetic locking cover.
  • the containing body will be equipped with internal removing paddles associated to its own internal wall, associated to its axle, or it will even lack of such paddles.
  • the axle of the mixer will be driven by any type of conventional motor or actually it will be manually driven, when its capacity and practical application make it advisable.
  • the mentioned removing inner paddles can be equipped with their own movement, that is instead of being installed either on the internal wall of the container or on the rotation axle itself, they will be installed on an independent axle, preferably coaxial with the container axle and equipped with own driving means which allow to promote the efficiency thereof.
  • the mentioned paddles have the shape of blades that, besides acting as removing elements, they act as cutting elements, which give the mixer a new operative dimension, precisely of a grinding-mixing device.
  • the mixer which is proposed is formed from a hollow cylindrical body (1), based on any adequate material, which can be steel, plastic, glass, etc., as a function of the type of materials to be mixed and of the capacity that the mixer should have, showing such cylindrical body (1) one of its bases (2), totally closed, while on the other base it is established a closed sector (3) and an open sector (4), determining a filling-emptying hood inlet, being this mouth (4) supported by a cover (5), that in the example of the practical embodiment represented in the figures is a tiltable cover through a hinge (6), but that can be equipped with any other locking means, provided that it establishes over the mouth (4) a hermetic lock, which obstructs the flowing out of liquid products which may participate in the mixture, in the normal operation of the mixer.
  • any adequate material which can be steel, plastic, glass, etc.
  • the body (1) constructed in this way is passed through by an axle (7), with the special characteristic that such axle adopts a very inclined disposition, in reference to the geometrical axis of the cylindrical body (1), in such a way that it emerges through one of its bases (3) in a very off-centre position and opposed to the mouth (4), at the same time to its other base (2) being also with the. same off-centring level, but in contrast, in such a way that the middle point of the axle (7) sector located in the inside of the mixing chamber, crosses itself with the geometrical axis of the cylindrical body (1) in correspondence with the middle point of the latter.
  • axle (7) rests by its ends, by means of bearings or other appropriate antifriction elements, which are not represented in the figure, on supports (8) schematically represented in figure 1 and that in practice will remain integrated in a sole support chassis.
  • This axle (7) is strongly linked to the bases (2) and (3) of the container body (1), in such a way that its rotating movement pulls such body, rotating movement that can be indistinctly produced to the right or to the left, such as it is shown by the arrows of figure 1, and which driving movement, previously mentioned, can be carried out by any type of electrical pneumatic, etc., motor, and even by hand.
  • the described structure is complemented with a series of internal paddles (9), which can be linked to the axle (7), as in the example of practical embodiment represented in the figures, but that equally may be linked to the internal face of the container body (1), with the shape of the figures or with any other one which may be considered appropriate, and that actually may not exist.
  • the axle (7) is intended to adopt a horizontal disposition, in such a way that in its rotating movement the container body (1) may adopt the position represented in figure 2, in which its mouth (4) adopts an upward extreme position, corresponding to the filling, preferably until the level with the reference (10) in figure 2, where the mixture of materials appears represented by means of dots, starting from this position and after the hermetic locking of the cover (5), supported by means of blocking, not represented, that guarantee a perfect stability thereof in such situation of locking, the axle (7) rotating movement, and consequently of the same container (1), determines a mass mobilization which is transversally displaced, that is raised pulled by the paddles (9), and that besides is longitudinally displaced from one to another end of the container body, as it is derived from the graphic comparison of the figures 2 and 3, or, in another words, the mobilization of such mass is carried out in correspondence with the three axis of a Cartesian coordinates system, that is in optimal conditions so that
  • the stopping of the mixer must be carried out in a way that its mouth (4) remains in a lower limit position, in which the opening of the cover (5) supposes the total and automatic discharge of its content.
  • the above mentioned removing paddles are materialized in a propeller (11), preferably formed by four paddles, in a way that two of the paddles of such propeller are of opposite pitch to the other two, as it is specially seen in figure 4.
  • the special shape of these paddles (11) acts as if when the mixture is transported by gravity from one base to the other of the cylinder (1), such paddles tend to displace the mixture in an opposite direction, improving the conditions of the removal.
  • these paddles can form a sole propeller (11), as in the example of practical embodiment represented in figure 4, or also they can form different propellers conveniently distributed along the axle (7).
  • the propeller (11), or in its case the different propellers established in the cavity of the container body (1), are physically independent from the axle (7), in such a way that, while through such axle (7) the cylindrical container (1) receives the movement from the corresponding motor (12), the propeller or group of propellers (11) receives the independent movement of a second driving group (13), to which effect and as it has been schematically represented in figure 5, the propeller (11) can be installed over a hollow axle (14), coaxial with the axle (7) but independent thereof, closely connected with it, for example, through bearings. In this way, as the movement of the propeller or propellers (11) is not depending on the movement of the container body (1), it is possible an important improvement in the removal conditions of the product placed in such container (1).
