Definitions

  • helical screw rotors have the disadvantage of being expensive manufacturing and this fact are reserved for applications in which the other types of rotors may not be suitable.
  • the vane rotors On their side, the vane rotors have the disadvantage of offering too much passage section (angular sectors between successive palettes peripherally).
  • pallets which are often fixed by welding on the central shaft of the rotor, can prove fragile especially in the case of products with very large viscosity.
  • the object of the invention is to overcome the disadvantages currently known devices and to propose an improved device that responds better, especially as to its efficiency and cost, the requirements of the practical in some applications.
  • the invention proposes an in-line dynamic mixing device as explained in the preamble which, being arranged according to the invention, is characterized in that the rotor supports a multiplicity of successive coaxial disks, each disk having a plurality of holes, and the casing supports a multiplicity of successive coaxial disks, each disk having a central orifice for the passage of the rotor and a plurality of holes, the rotor disks and the housing disks being mutually axially alternated and spaced from each other by successive intervals.
  • the discs fixed or rotary, are substantially perpendicular to the axis of rotation of the rotor and bear almost no axial effort.
  • the device thus constituted is therefore very robust in same time as it is of economic manufacture, the perforated discs which can be mass produced by conventional machining means.
  • the drive of the rotor can be provided by means of motorization, especially motor electric, commonly available and therefore of a lesser cost.
  • a mixing device presents a very large number of structural parameters and the adjustment of one or more of them allows a adaptation to mixing conditions and / or very diverse products.
  • holes are distributed circularly in the vicinity of the periphery of at least some rotor disks and / or less some crankcase disks. But he is also possible to have holes arranged, particularly circumscribed, outside the periphery of at least some rotor disks and / or less some crankcase disks.
  • holes at least some rotor discs and / or holes at least some casing disks are round to treat products of small granulometry or liquid or non-round shape (particularly angular such as triangular) to process more products large granulometry or lumpy.
  • holes of different shapes may, where necessary, be provided on the same disc.
  • holes of less some adjacent disks respectively of the rotor and housing are centered on circumferences respective substantially identical, ie move substantially opposite each other; or well be centered on respective circumferences significantly different if we wish to better disrupt the flow of the veins of the product to be mixed.
  • the holes of at least some adjacent discs respectively of the rotor and the carter are in identical numbers, especially on at least one axial section, or even the whole of the length, or on the contrary that they are in numbers different, especially on at least one axial section, over the entire length.
  • these two provisions can be combined on sections successive.
  • the intervals between the successive disks belonging alternately the rotor and the casing are equal on at least one section axial. But, if it proves useful for example to hold account for possible variations in viscosity of the product treated between entry and exit as the product is homogenized, it can be envisaged that the intervals between successive disks belonging alternatively to rotor and crankcase differ axially, for example this variation can intervene by successive axial sections; in particular one can foresee that these intervals vary gradually over at least an axial section; In particular, it is possible to envisage that the intervals are smaller in the vicinity of the outlet that near the inlet if the viscosity of the mixed product decreases or is larger if the viscosity of the mixed product increases.
  • the rotational speed of the rotor constitutes of course an important parameter of adjustment of operating conditions of the device for obtaining a desired result.
  • the housing has a single inlet, in particular disposed coaxially at one of its ends, for the admission of a flow formed by the meeting of at least two primary products, which means that the meeting of primary products was carried out before the device of the invention, for example using a first T-mix (coarse mix) located upstream from the entrance.
  • a first T-mix coarse mix
  • crankcase can be provided has at least two entries for the admission of respective primary products to be blended, thereby save the first mixer located upstream, the inputs can all be located parallel to the axis at one end of the housing, or at least some entrances can be arranged laterally for example to achieve staged blends of several products.
  • each provision can be implemented on the the whole length of the rotor, or only on one axial section of the rotor, successive axial sections can be equipped differently.
  • a dynamic mixer device in line according to the invention intended to intimately mix two or more products primary, has a substantially elongate housing 2 and internally cylindrical of revolution with at least one input 3 (here arranged axially at one end of the housing) for said product to be mixed and at least one output 4 (here arranged laterally) to evacuate the product intimately mixed.
  • the device 1 also comprises a rotor 5 extending internally to said housing 2 and coaxially to it, and means for driving in rotation (no shown in Figure 1) are intended to lead to rotation (arrow 6) the rotor 5.
  • the rotor 5 supports a multiplicity of disks 7 successive coaxials, each disk 7 having a plurality of through holes 8, a remaining game 9 between the outer edge of each disk 7 and the wall of the casing 2.
  • the casing 2 internally supports a multiplicity of successive coaxial disks 10, each disc 10 having a central orifice 11 for the passage of the shaft 12 of the rotor 5 and a plurality of holes 13 through, a game remaining between the inner edge of each disk 10 and the shaft 12 of the rotor.
  • the discs 7 of the rotor 5 and the discs 10 of the casing 2 are mutually axially alternated and spaced from each other by respective intervals d .
  • the discs can be held apart by spacers and the stacks are held tight by suitable clamping means (clamping rods not shown for the housing discs and axial screw and shoulder for the rotor shaft).
  • the device according to the invention as it just exposed can give rise to a very big number of alternative embodiments because of the numerous parameters that can be adapted in the structure.
  • the holes are not arranged circularly, or even are arranged randomly.
  • the holes 8, 13 illustrated in Figures 1 to 5 are round in shape, but it is perfectly conceivable that they have shapes other.
  • holes may be provided polygonal, in particular triangular.
  • Figure 5A is illustrated by way of example a fixed disk 10 provided with triangular holes 13 (only one being drawn) pointed directed towards the center and a rotating disc 7 (only one fragment of it is drawn) provided with round holes 8.
  • Figure 5B is illustrated as another example a fixed disc 10 provided with triangular holes 13 pointed directed outward and a rotating disc 7 (only one fragment of it being drawn) provided with holes 8 round.
  • the round and triangular holes being dimensioned mutually so that, in alignment situation, each round hole is entered in the triangular hole opposite.
  • the holes 8 of the rotor disks 7 and the holes 13 discs 10 of the casing 2 are located on substantially identical circumferences, so that they are sequentially put into coincidence in some relative angular positions of the rotor disks and the casing.
  • such an arrangement is not mandatory and it can be envisaged that the holes of the disks rotor and the holes in the crankcase discs located on different circumferences so that they never be in coincidence as shown in the figure 6 (only a rotating disk fragment 7 being shown) or that they are sequentially only in coincidence partial.
  • Another important parameter of the operation of the device lies in the intervals between successive disks 7, 10.
  • all the successive disks 7, 10 are spaced apart from one another by equal intervals of value d .
  • a simple implementation of this arrangement consists, as illustrated in FIG. 7, in arranging the rotor 5 in several successive sections T 1 , T 2 , T 3 (for example two or three sections) in which the intervals have different values.
  • the quantity ⁇ could itself be a constant quantity, or a variable quantity depending on the index i , or even a percentage of a basic value or the value of the preceding interval.
  • the holes 8, 13 opposite adjacent discs 7, 10 respectively belonging to the rotor 5 and to the casing 2 have substantially identical sections on at least one axial portion of the rotor. ; for example the holes 8, 13 of round shape illustrated in Figures 1 and 2 have substantially the same diameter over the entire length of the rotor.
  • this arrangement is not mandatory, and it is possible to envisage holes 8, 13 respectively having different sections on several axial sections as illustrated in FIG. 8 (here this arrangement is associated with identical intervals between the disks). successive), or continuously variable sections on at least one axial section.
  • the holes 8, 13 of round shape have different diameters ⁇ 1 , ⁇ 2 , ⁇ 3 , which here decrease on respective axial sections T 1 , T 2 , T 3 of the rotor for a mixture having a decreasing viscosity (these diameters being increasing in the case of a mixture with increasing viscosity).
  • the rotational speed of the rotor is an important parameter for setting the conditions operation of the device required for a given application. Adaptation of games between discs and respectively the crankcase and the rotor allows also affect the flow of the product through the device.
  • Figure 9 is illustrated by way of example a mixing device according to the invention shown in its set (the same numerical references to the figures 1 and 2 are used to designate the organs identical).
  • the mixer is supposed to be analogous to that of Figure 1, with alternating discs 7, 10 which are separated by equal intervals and which are provided with holes 8, 13 round as shown in Figure 2.
  • a first mixer for example a T-mixer
  • entry 3 which, in the illustrated example, is an entry axial axis located coaxially with the rotor 5.
  • the casing 2 is secured to a frame 14 which is itself fixed on a mounting base 15.
  • Shaft 12 of rotor 5 is integral in rotation of the output shaft 16 of a gear reducer speed 17 fixed to the frame 14 (or whose frame 14 is part integral of the crankcase), the speed reducer 17 being itself coupled to the output shaft of an engine Electric drive 18.
  • a mixer device dynamic online so arranged uses materials commonly available commercially, and can be realized with a relatively reduced cost.
  • the housing may have a single input, for example axial as shown in the figure 9, for the simultaneous admission of primary products; but it is also possible to envisage several entrances, including an entrance or several entrances to a end of the crankcase and another or more entrances located laterally on the housing: it becomes then possible to perform a staged mix of several products; for example two products are introduced, together or separately at one end of the housing and are mixed on a first section of the crankcase, then a third product is introduced laterally and is mixed with the previous ones on a second section of the housing, etc.
