Definitions

  • This invention relates to apparatus for the continuous treatment and processing of solid or liquid materials-or mixtures thereof which comprises a-rotatable cylindrical processing chamber having feeding and discharging means positively connected thereto at each end thereof.
  • the present invention relates to apparatus for the continuous treatment and processing of solid and/or liquid materials, characterized by a symmetrical or asymmetrical rotary element provided within the processing chamber for rotation in the region of the end flange of the feed means, the speed of rotation of said rotary element being different from that of the processing chamber.
  • the rotary element is in the form of a scraper and is eccentrically mounted, with respect to the treatment chamber, for free rotation therein.
  • apparatus we mean rotary kilns, drum-type furnaces, mixers, rotary mills, drum mills, ball mills and similar apparatus.
  • the processing chamber of said apparatus may contain, depending on the materials to be treated, grinding elements such as spheres, cylinders or rods, which grind and mix the contents of the chamber.
  • Process materials for the purposes of this invention are, for example, melts, solutions, pastes and powders which become converted to the solid state on passing through the apparatus.
  • treatment and processing we mean, in particular, such operations as mixing, homogenizing, grinding, stirring, dispersing, dissolving, heating, cooling and drying.
  • reactions such as those between melts and gases or between melts and liquids can be carried out.
  • Suitable freely rotatable symmetrical or asymmetrical rotary elements are cruciform, stellate, disc-shaped, serrated and annular scrapers, generally provided with sharp edges at their periphery.
  • the arms of cruciform or stellate rotary elements may have a variety of cross-sections. Deeply undercut triangular sections of adequate flexural strength are ad vantageous. lf provided with special tips, the scraper may also serve to scrape a portion of the cylindrical surface of a mixing autoclave so as to increase the desired effect of reducing incrustations in the particularly critical corner region.
  • the scraper achieves, in its region of operation, a good to very good mixing effect which may assist the process and improve the quality of the product, since better mixing of the components leads to quicker conversion and better heat transfer. Further improvement of the heat economy may be achieved by making the rotary element coolable or heatable.
  • the apparatus may be subdivided into separate reaction zones by partitions of various designs.
  • the degree of eccentricity determines the value of said speed differential.
  • the rotary element which is usually in the form of a scraper, is entrained by the friction occurring between the scraper and the chamber wall with product adhering thereto and also between the scraper and the charge consisting of mixing or grinding elements and product.
  • the rotary element is substantially dependent on the coefficient of friction between the material of which the scraper is made and the product and consequently varies as the consistency of the product changes.
  • FIGS. 1 and 2 An embodiment of the apparatus of the invention is described below by way of example with reference to the accompanying FIGS. 1 and 2, in which it is illustrated diagrammatically and in which:
  • FIG. 1 shows a cross-section of a freely rotatable and eccentrically mounted rotary element
  • FIG. 2 is a perspective view of the stellate rotary element used as scraper.
  • the apparatus consists of a cylindrical processing chamber 1 having an internal flange 2 at one end thereof.
  • the hollow shaft 3 is mounted in the fixed part 18 by means of radial bearings and axial bearings 11 located in positions upstream of the flange 2.
  • the free end of said hollow shaft which is provided with a stellate rotary element 4 to serve as scraper, projects into the chamber 1.
  • the rotary element 4 consists of welded steel plates 5, 6, 7 and 8 and is mounted eccentrically to the processing chamber 1.
  • the bearings 10 and 11 are sealed by means of retaining rings 12 and also by means of sealing washers 13 provided on the side of the said retaining rings remote from said bearings 10 and 11. Clamping of the bearings in the axial direction is effected by a nut 14. Sealing washers 15 prevent the penetration of product into the annular gap between the stationary charging means (not shown) and the rotating hollow shaft 3.
  • the cylindrical processing chamber 1 is driven by a chain-wheel 16 whose motion is transferred thereto via the bearing box 17 and the said flange 2.
  • the feed of product takes place through the hollow shaft 3.
  • the arms 9 of the rotary element 4 are immersed in the charge contained in the processing chamber and consisting of grinding elements and product and are entrained thereby by friction. They thus keep down the formation of incrustations of product, particularly in the region between the cylindrical wall of the chamber 1 and the flange 2.
  • An apparatus for the continuous treatment and processing of solid or liquid products which change physical state during treatment comprising:
  • a rotatable processing chamber said chamber having a substantially right cylindrical shape with an arcuate side wall and two substantially flat end walls, the first of said end walls having means through which said product is charged into said chamber, the second of said end walls having means through which said product is discharged from said chamber; grinding elements within said processing chamber;
  • scraper element arranged for rotating movement about an axis parallel to and eccentric with the longitudinal axis of said processing chamber, said scraper element being mounted freely rotatable about said parallel axis near the first of said chamber end walls; whereby said scraper is entrained to rotate by friction occuring between said scraper and said chamber first end wall and the product adhering thereto, and friction between the surface of said scraper and-the product and the fillet region formed by said arcuate wall and the first of said end walls is kept free of product deposits through a differential in the speed of rotation of said scraper and said processing chamber.
