Definitions

  • ABSTRACT A high speed mixing machine in which power driven tools are arranged to rotate in a mixing vessel to produce a forced vortex-like movement of the material being mixed has a plurality of separate tools rotatable in coacting compartments of the vessel which merge with one another so that the material, particularly synthetic material to be processed and/0r mixed e.g. with other material in the form of additives or liquids, is continuously transferred from one compartment to another of the vessel.
  • the present invention relates to mixing machines particularly, although not exclusively, for processing synthetic materials or similar powdered, granular or fine-fragmented substances, with or without the introduction of additive materials or liquids, said machine having a mixer vessel and power-driven tools rotating therein which by centrifugal force produce a funnel-like movement in the material.
  • Machines of this kind which are also referred to as high-speed mixers, have a substantially cylindrical basic vessel in which tools co-axially assembled upon a drive shaft, rotate, being driven by an appropriate motor.
  • the drive shaft can project into the mixer vessel either through its base or through its top.
  • Known machines of this kind are limited in terms of size and performance. This limitation is due primarily to the heating which is produced in the material as a consequence of the rotational movement of the tools, and this heating must not exceed a certain level if damaging heat-induced phenomena are to be avoided.
  • the height of the mixer vessel is restricted by the fact that the level of the material in the vessel may only rise above the'working plane of the tools by a specific amount if a funnel-like flow of material is to be produced in the vessel, the material executing a combination movement composed of a rotational motion about the tool axis and along the external wall, with an axially upward motion and an axially oppositely directed motion toward the vessel center. If the level of the material in the vessel exceeds a certain height, then the kinetic energy of the tools is compensated by the internal resistance presented by the material and the development of the critical funnellike flow pattern which determines the production of the mixing and preparing effect, is impeded.
  • the present invention provides a mixing machine in which power-driven tools are arranged to rotate in a mixer vessel and by centrifugal force produce a funnellike movement in material being mixed in the vessel, the vessel being made up of a plurality of coacting vessels having merging coacting mixing spaces, each with its own mixer tools, the merging coacting mixing spaces combining to form a common mixer space in which a continuous transfer of material from one coacting mixing space thereof to another will occur on operation of the tools.
  • said coacting mixing vessels have mutually merging coacting mixing spaces.
  • the present invention may provide a large-capacity mixer the capacity of which can be designed arbitrarily, independently of processing limitations, and which can process in one operation charges of a size which is determined simply by the requirements of the processing industry. Even where large charges are involved, using the machine in accordance with the invention it is possible whilst reducing the mixing time to achieve a qualitative mixing result which is far superior to that obtainable by mixing machines of conventional design. This goes hand-in-hand with a'simplification in the loading outlay, in the weighing of the charge constituents and so on, whilst, furthermore, there is better exploitation of the capacity of further processing machinery, e.g. extruders.
  • the absolute uniformity of the material bulk in a charge moreover ensures that there is no occurrence of quality fluctuations in the end-product, e.g. of the kind which could stem from discrepancies in the quality of preparation in parallel operations carried out in different machines of corresponding coacting capacities. It is furthermore an advantage that even where large vessel capacities are involved, a comparatively low vessel height can still be maintained.
  • a separate drive motor is provided which, having -a correspondingly lower power, imposes lower start-up power peaks on the supply system.
  • the speed of the tool or tools in each coacting vessel is capable of individual control and, in particular where separate drive motors are provided, this presents no difficulty. Alteration of the tool speeds, independently of one another, makes it possible to influence the flow pattern of the material being mixed and to produce zones of differing mixing intensity, differing heating and the like.
  • the coacting vessels are identical in size and shape. With this kind of design particularly, economical production is achieved by the use of the same available machine tools and other production equipment. Instead of this, however, it is equally possible for the volumes of the coacting mixing spaces defined by the coacting vessels to differ from one another, and this provides a further possible way of adapting the mixing and preparation operation to special requirements. Because, with this kind of design too, the overall material flow passes through all the coacting vessels, zones are created in which the material is differently affected and which enable special mixing effects to be produced.
  • the confining walls of coacting mixing'spaces belonging to coacting vessels which exchange a material flow with one another, should intersect one another in a manner which ensures an unimpeded material transfer flow.
  • the transfer opening between the coacting mixing spaces, which is produced by this intersection, should be designed in accordance with the dimension of the funnel-like material flow in the radial direction, in order to prevent any build-up or stagnation of material in the transitional zone.
  • the tools of the coacting vessels conveniently consist in each case of a set of several coacting tools arranged co-axially above one another at an interval, in a manner which for that matter could equally be used in conventional machines.
  • the operating planes of the individual tools of tool sets in the coacting vessels which co-operate with one another are angularly offset in relation to one another. This offset creates a material flow in different planes and contributes in a marked measure to the development of a continuous and unimpeded exchange of material between adjacent coacting vessels. At the same time, this measure improves the intensity of the mixing. A further improvement in the intensity of mixing can be achieved if, in accordance with yet another feature of the invention, the fields of operation of the tools in adjacent coacting vessels overlap.
  • propeller-like tools should be provided, having a pitch such as to impart to the material a component of movement in the axial direction and in accordance with a feature of this invention the pitch of the tools of the respective coacting vessels is different and this further promotes the attaining of a continuous material flow pattern which extends through all the coacting vessels.
  • the tools can be identical with one another and be driven synchronously so that they rotate in the same direction. Instead of this, however, the tools may equally well be given a mirrorsymmetrical design in relation to one another and be driven synchronously but in opposite directions of rotation.
  • the floor levels of adjacent coacting vessels are offset in relation to one another in the direction of the axes of rotation of the tools.
  • the degree of offset advantageously corresponds in this context at least to the effective axial working height of one of the individual tools rotating adjacent the floor, and these tools are themselves offset axially in relation to one another in accordance with the offset between the floors.
  • the direction of offset of the floor levels of the coacting vessels, as well as of the tools adjacent the floor in each case will correspond with the direction of offset of the other individual tools of the sets.
  • the operating areas of the individual tools located adjacent the floor may, moreover, be arranged to overlap one another.
  • This kind of design at the same time ensures complete discharge of the overall vessel, leaving no residue, after the completion of an operating cycle.

  • the inner wall 5 and 6 in each case defining the coacting mixing space of the coacting vessels 2 and 3, has a substantiallycylindrical form. These walls intersect one another and in so doing define a common transfer opening 7 which extends over the full height of the vessel 1 and, in the example illustrated, has a width corresponding approximately to the radius of a coacting vessel.
  • the intersection between the internal walls 5, 6 of the coacting vessels, which determines the width of the transition opening 7, is arranged in such fashion as to achieve an unimpeded flow of material at the transition zone, the dimension of the radial component of the funnel-like flow pattern during operation being a critical quantity in this context upon which to base design.
  • the overall vessel is of double-walled form and it is possible, in the interspace 8 between external wall 9 and the vessel walls 5, 6, to arrange for the introduction of a coolant or heating medium, e.g. water, oil or the like.

  • the tools 10, ll produce in the material contained in the overall mixing vessel 1, a motion such that it describes a funnel-like flow pattern. Viewed in a direction parallel to the axes of rotation of the tools, the flow described a figure-of-eight pattern, the material continually transferring from the coacting vessel 2 to the coacting vessel 3 and vice versa.
  • the material commencing for example from the bottom paddles 21, follows a rising curving path, enters the range of effectiveness of the paddles 25 and returns in the course of the curving trajectory to the range of effectiveness of the paddles 23 whence it passes back, after moving towards the center in a direction substantially parallel to the axis of rotation, into the range of effectiveness of the paddles 21. Accordingly, commencing from the range of effectiveness of the base paddles 24, the material rises into that of the center paddles 22 thence into that of the upper paddles 26, whence it passes back into that of the base paddles 24.

  • the design of the machine in FIGS. 1 to 4 can be influenced by regulating the speed of rotation of the tools 10, 11, by changing the direction of the tool motion, e.g. in the case of symmetrically designed tool paddles, by altering the offset in the planes of operation of the tools, by altering the angle of incidence of the tools and so on, all in accordance with the particular requirements of the quantities of material to be prepared in the operating cycle, so that the most varied circulatory movements can be produced in the material either as a whole or in zones.
