Definitions

  • the invention consists in a mixing device comprising cooperating rotor and stator elements, wherein the rotor element is mounted at one end of an elongated shaft adapted at an opposed end thereof for coupling to an output shaft of an electric motor and supported near to the rotor element by bearing means provided on the stator element, and the stator element is supported by means comprising a plurality of elongated support members each of which extends in a direction away from the stator element, axially and radially outwardly of the rotor shaft, to a support plate adapted for securing to the motor housing.
  • FIG. 1 is a perspective view of a mixing device according to the invention
  • FIG. 2 is a section on the line II of FIG. 1.
  • the mixing device shown in the drawings is suitable for mixing materials containing hard pieces of resin, stone, etc., where there is a danger of a lump of the material momentarily becoming engaged between cooperating rotor and stator elements of the device and subjecting the device to high torsional forces.
  • a rotor element 1 of the present device consists of four equiangularly spaced blades 3 secured to one end of an elongated shaft 5 adapted at its other end for connection to an output shaft of an electric motor 7.
  • the motor 7 is mounted on an upright stand 9 and is arranged with its output shaft extending vertically downwardly.
  • a stator element 1 1 includes a pair of annular end walls 13 and a cylindrical sidewall 15 which is clamped between the end walls 13 by a pair of axially extending screws 17.
  • the sidewall 15 has an internal diameter slightly greater than the diameter of the volume swept out by the rotor blades 3 upon rotation thereof.
  • the rotor l is arranged within the stator 11 and the rotor shaft 5 extends upwardly through a central aperture in the upper end wall 13 of the stator 11 and through an apertured boss 19 formed on an outer surface thereof.
  • a bush 21 is fitted into the boss 19 and serves to provide a bearing surface for the lower end of the shaft 5.
  • the lower end wall 13 of the stator 11 is formed with an aperture which has a diameter substantially equal to the internal diameter of the sidewall 15 and serves as an inlet for a flow of material into the device.
  • a series of circular apertures 23 in the sidewall 15 serve as outlets for the material.
  • each slot extending from one end of the tubing to a location spaced a short distance away from the opposed end and increasing in width, or angular extent, in a direction away from the open end thereof.
  • Each section of material between the slots then has the end thereof adjacent the open ends of the slots forced radially outwardly.
  • the support formed by these processes consists of a tubular element 25, which is the unslotted, end section of the original tubing, and a pair of elongated support members 27, which are formed of the material between the slots in the original tubing.
  • Each support member 27 is arcuate in cross section and increases in angular extent in a direction away from the tubular element 25.
  • the boss 19 on the stator 11 is fitted into the tubular element 25 and is secured thereto by welding.
  • the support members 27 are welded to an annular horizontal plate 29.
  • annular plate 29 is bolted to the housing of motor 7 with the output shaft of the motor extending downwardly through the central aperture in the plate.
  • the rotor shaft 5 and the output shaft of the motor are connected together by a pin.
  • the stand 9 for the motor 7 is arranged along side a mixing vessel (not shown) with the motor shaft extending vertically downwardly towards the material in the vessel and the rotor l and the stator 11 immersed within the material.
  • the above-described device has a stator 11 whose sidewall 15 has an internal diameter of approximately 1.1 inches and an axial length of approximately three eighth inches.
  • the tubing from which the stator support is made is 14 SWG material and has an outside diameter of 1 inch and an overall length of approximately 11 inches. At their closest points the upper ends of the two sections of material intermediate the slots in the tubing are spaced apart by approximately 1% inches.
  • tubular element 25 and support members 27 are replaced by two or more rods.
  • Each rod has a lower end thereof secured to the upper end wall 13 of the stator 11 and an upper end thereof secured to the plate 29, the rod extending upwardly and radially outwardly of the shaft 9.
  • a mixing device comprising a stator element having a sidewall, an inlet aperture at one end thereof and outlet aperture means formed in the sidewall, bearing means provided at the other end of the stator element, a rotor shaft adapted at one end thereof for coupling to an output shaft of a motor and supported near to the other end thereof by the said bearing means, a rotor element which is mounted on the rotor shaft, within the stator element, said rotor element including a plurality of blades whose radially outer ends are adjacent to the said sidewall of the stator element, and support means for the stator element comprising a support plate adapted for securing to the motor housing, and a plurality of elongated support members each of which extends with increasing width in a direction away from the stator element, axially and radially outwardly of the rotor shaft to the said support plate, and wherein said support members are arcuate in cross section, whereby upon rotation of the rotor shaft the rotor blades force material entering the stator element
  • the support means includes a tubular element which is secured to the stator element, coaxially of the rotor shaft, and elongated support members which are formed integrally with the tubular element and extend from the tubular element to the said support plate.
  • stator element is formed with an apertured boss which is fitted within the said tubular element, and the bearing means are provided within the said boss.
  • bearing means comprise a bearing bush which is fitted within the said apertured boss.
  • bearing means comprise roller bearings which are located within the said apertured boss.
