Definitions

  • the present invention concerns a granulating device for reducing a mass of material to granular or particulate form, which has a material-working member, more particularly a continuously operating worm co-operating with radial outlet nozzles of the surrounding housing.
  • Granulating devices with worm mechanisms which serve for the mixing, kneading and extruding of plastic substances, especially synthetic materials.
  • the revolving worm works and compresses the product to be granulated in the axial direction through a plate having nozzles, and which is fitted with a rotating knife which cuts the strands of material extruded from the nozzles into granular or particulate form.
  • Many of the newer products cannot be worked without difficulty with such a granulating device as the sticky granulate adheres to the knife and thereby lowers its etficiency.
  • the object of the invention is to provide a granulating device in which the disadvantages cited above are avoided. More particularly, satisfactory working of sticky products in continuous operation is to be obtained wherein the material particles do not adhere, neither to the knife nor to the inner wall of the reception chamber,
  • the granulating device has a material-working apparatus, more particularly a continuously operating worm inside a housing having outlet nozzles. These nozzles, arranged at the oulet end of the worm, are disposed in a hollow body provided with substantially radial bores. Revolving cutting members are provided which contact the outer surface of the hollow body with their cutting edges.
  • the hollow body is preferably of a cylindrical or frustoconical shape.
  • rotating fan blades are associated with the cutting members, which produce a stream of air which additionally accelerates and cools the particles of material which is outwardly centrifuged by the cutting members.
  • a heating medium may be circulated in the bores or electrical heating means may be arranged therein.
  • FIG. 1 is a partly sectional side elevational View of one embodiment of the granulating device according to the invention
  • FIG. la is a partial sectional view illustrating a cylindrical apertured member as a modification of the conical member shown in FIG. 1;
  • FIG. 1b is another partial sectional view showing optional drive means for oscillating the cutting devices together with the bearing case;
  • FIG. 2 is a partly sectional view of the major inner components, taken along line 11-11 of FIG. 1, with the knives and the fan blades interconnected;
  • FIG. 2a is a view similar to that of FIG. 2 but showing a modification wherein the knives are supported for rotation separate from that of the fan blades, also showing a separate support for the latter;
  • FIG. 3 is an end view of the granulating device, taken from the right-hand side of FIG. 1.
  • the illustrated granulating device has a housing 1 in which a material-working member is disposed in the form of a worm 2 capable of continuous operation.
  • the housing 1 is fixed to the floor or ground in a conventionalmanner, eg by the intermediary of a foundation or base 1a, as shown in FIG. 1.
  • a conventional drive is shown at 2a for the worm 2.
  • a plurality of outlet nozzles is arranged at the right-hand end of the housing 1, as viewed in FIG. 1, being constructed as a hollow body of rotation in the form of an outlet support 4 and a conical apertured member 5 (FIG. 1).
  • Stirrup clamps 3 and '3' are provided to secure the outlet nozzle support 4 onto the housing 1.
  • the apertured member may be given a cylindrical shape, as shown at 5 in FIG. 1a while FIG. 1 shows the conical member 5.
  • the conical apertured member 5 is provided with radially aligned apertures 6 to allow passage of the material to be granulated.
  • Longitudinal bores 7 serve to accommodate a heating fluid or medium for the apertured member 5.
  • An extruder 8', forming the extension of a trunnion 8, extends into the interior of the apertured member and has bores 8" which form extensions of the bores 7.
  • the trunnion 8 is flanged to the end flange of the nozzle support 4 (e.g. by way of a number of circumferential bolts).
  • the trunnion 8 is arranged coaxially with the worm 2, and it carries a rotatable bearing case 11 by means of bearings 9 and 10.
  • the feed of the heating medium to bores 7, 8" takes place by means of a pipe 12 attached to the mouth of the bore 7 while a pipe 12 is provided for allowing the heating medium to be discharged therefrom.
  • the heating medium which enters the longitudinal bores 7 through pipe 12 is fed through the bores 8" of the extruder 8 and flows back into the external heating system through further longitudinal bores 7 and pipe 12'.
  • the heating system is not shown in the drawing.
  • electrical heating could be provided by means of electric heating elements disposed in the bores 7, 8.
  • FIG. 1 only shows one system of elements 1315.
  • a reception chamber for the material particles is shown at 20 (see FIGS. 1 to 3).
  • This chamber 20 surrounds the apertured member 5 along with the rotating knives 14 and the fan blades 15. It is suggested to provide lateral rotating walls 16 and 16' attached to the knife arms 13.
  • FIG. 1 the right-hand side of the chamber 20 is shown with releasable or detachable flanged portions, for cleaning and maintenance purposes of the inner mechanism.
  • the bearing case 11 is provided with a bore 18 which connects with corresponding bores 18 in the knife arms 13, these bores terminating in outlet openings or spraying nozzles 19 at the outlets and adjacent the respective fan blades 15.
  • Lateral yokes or brackets attached to the outer walls of the reception chamber 20 (see FIG. 3) hold a stufling box 17 which is thus connected with the conical flange of the nozzle support 4.
  • a liquid or gaseous medium is fed into the stuffing box 17 through an appropriate inlet pipe 18a, thence through the bores 18 of the bearing case, the corresponding bores 18 in the knife arms 13 andto the spraying nozzles 19 adjacent the fan blades 15 so as to form a protective film thereon, as well as on the inner wall of the reception chamber 20, which prevents the material particles from adhering thereto.
  • the medium should conveniently be guided as near as possible to the cutting edges of the knives 14. In this way the affected surface will be extensive and the cooling of the knives improved.
  • a V-belt 21 and a conventional drive 11a are provided to drive the bearing case 11 (FIG. 1) together with the attached cutting devices.
  • An adjustment nut 23 with a lock nut 24 serves as an abutment against this displacement.
  • By adjustment of the nut 23 the play between the knives 14 and the apertured member may be adjusted during operation as desired.
  • nozzles 25 are provided for additionally spraying the inner walls of the reception chamber 20.
  • two diametrically opposed knives 14 are shown, as a matter of example, so that on each revolution of the case 11 each strand of material issuing from the apertures 6 will be out twice. Should only a single cut be required to take place at a similar cutting speed, the knives can be provided such that their length corresponds to only half the length of the outer conical surface line of the apertured member 5 as shown at 14 in the modified partial view of FIG. 1a. On the other hand, it is also possible to provide additional knife arms, for example four or six (not illustrated.)
  • FIG. 2a shows, in an exemplary manner, drive means 15b, in the form of a motor-driven pinion, acting upon a toothed outer rim of the support or crown 15a. The latter may be supported by inner bearings, as shown.
  • FIGS. 2 and 3 show such a fan at 20a, for producing the additional air stream for the material particles.
  • an outlet or discharge 20b has been shown in the drawings for the material particles.
  • a granulating device comprising, in combination, a
  • a material-working apparatus in the form of a rotatable worm having outlet means arranged at the outlet end of said apparatus, said outlet means being in the form of a channeled and apertured member having substantially radial bores for the passage of the material upon rotation of said worm, at least one rotatable cutting member supported substantially coaxially with respect to said apparatus and on the side of said apertured member facing away therefrom, each cutting member having a cutting edge in linear contact with a portion of the outer surface of said apertured member, and at least one rotatable fan blade connectable with a respective cutting member, said cutting members and said fan blades when aligned presenta ing a unitary curved profile tangentially contacting said outer surface of the apertured member.
