Definitions

  • ABSTRACT Apparatus for finely dispersing the components of suspensions having a suspension-receiving container with an end wall incorporating a stuffing box by means of which a shaft is journalled in the end wall for driving an agitator, and an elastic connection between the end wall and the remainder of the container.
  • the present invention relates to an apparatus for finely dispersing the components of a suspension.
  • great accuracy is required to ensure that the cylindrical suspension container, one of the end walls of which carries a stuffing box for a shaft carrying an agitator, is always located coaxially with the shaft, so that no bending forces are exerted on the shaft or the stuffing box, not only during production but also during fitting after routine cleaning and servicing operations.
  • apparatus for finely dispersing the components of a suspension comprising a container for receiving a suspension the components of which are to be dispersed; at least one agitator disposed in the container to act on the suspension; means for driving the agitator, sealingly mounted in an end wall of the container; and an elastic connection between the end wall of the container and the remainder thereof.
  • the apparatus may be used to perform a pulsating or milling action in a mechanically agitated mixture of the suspension with grinding elements.
  • FIG. 1 shows a side elevation of a first embodiment
  • FIG. 2 shows a detail view of the embodiment of FIG. 1 to an enlarged scale
  • FIG. 3 shows a section, on a line equivalent to the line Ill-Ill of FIG. 1, of a modified embodiment
  • FIG. 4 shows, partly in side elevation and partly in section on the line IV-IV of FIG. 3, the embodiment of FIG. 3.
  • an electric motor 3 is secured by screws 2 to a frame 1.
  • a belt pulley 4 of the motor 3 is connected by V-belts 5 to a second belt pulley 6 which is carried at one end of a shaft 7.
  • the shaft 7 is freely rotatable in bearings 8 and 9.
  • the shaft carries several, (in the present case six), agitating devices 10, which are spaced from each other by spacer tubes 11 and which, although they may be constructed anyhow, must, however, be dynamically balanced.
  • the shaft and agitating devices are held together by means of an end cap 12 and an end bolt 13.
  • the mode of operation of this crusher is as follows.
  • the cylindrical container is filled with grinding bodies through a filling opening 20, after which the suspension to be dispersed is caused to flow or be pumped in through the inlet connection.
  • the agitating apparatus rotating at a large number of revolutions per minute, generates the necessary pulsating effect of the grinding bodies in the mixture of the grinding bodies and the suspension.
  • the solids in the suspension thus become very finely dispersed, and the suspension leaves the cylinder again through the outlet connection 18.
  • the cover plate 14b is not rigidly connected to the cylinder cover 14a, but is connected thereto by means of an annular disc-shaped element or membrane 21, constructed of elastic material.
  • the membrane 21 is clamped externally in a ring 22 formed of two parts 22a and 22b, the ring 22 being secured to the cylinder cover 14a by screws 15.
  • the annular disc-shaped element 21 is clamped by means of a ring 23b to a support put together from a support flange 23c and a flange 23a.
  • a stuffing box 25 is secured in the flange 23a by means of I a nut 24.
  • a tube 26 carried by the shaft 7 can rotate with the shaft in the stuffing box 25. 7
  • FIGS. 3 and 4 show a further embodiment of the cylindrical container, and in particular its mounting.
  • individual retaining rings 28 are welded, on each of which two annular discs 29 and 30 are screwed.
  • rotatable shaft it is not essential that the rotatable shaft be horizontal; it could, for example, alternatively be vertical.
  • a mechanical agitator apparatus for finely dispersing the components of a suspension, comprising, in combination, a horizontally extending shaft; bearing means only at one end portion of said shaft for rotatably mounting the latter with the remainder of the shaft freely projecting beyond said bearing means: a suspension receiving container having a peripheral wall surrounding at least part of the remainder of said shaft and an endwall facing said bearing means; at least one agitator in said container and mounted on said shaft for rotation therewith; support means supporting said container substantially coaxially with said shaft; means sealingly mounting said shaft in said endwall; and
