Definitions

  • the invention relates to the use of a device with a cylindrical ring nozzle, in the upper part of which an inlet gap is provided, above which an inlet is arranged concentrically with respect to the cross section of the ring nozzle, and with a dispersion unit arranged downstream of the ring nozzle, to which an intensive mixer is connected, the Ring nozzle has a shape bent towards the dispersing unit.
  • a device for dispersing and dissolving polymer powders is known from EP-A-0 050 312.
  • This device has a straight, funnel-shaped ring nozzle, which is followed by a jet pump as a dispersing unit.
  • An inlet for the polymer powder and an inlet for carrier liquid are provided in the upper part of the ring nozzle.
  • the polymer powder entering through the central inlet hits the jet pump directly without being wetted by the carrier liquid beforehand.
  • the polymer powder and the carrier liquid are mixed and dissolved in a turbulent flow.
  • GB-A 1 493 462 describes a device for suspending substances which are swellable in water, such as e.g. Concrete, known, which has a funnel-shaped ring nozzle.
  • the inlet for the swellable substance is arranged above the funnel in the area of its circumference. For this reason, the substance is conveyed onto its wall in the upper section of the ring nozzle. This means that the substance touches the wall of the ring nozzle at a very slow speed.
  • the substance is not moistened at the point where it hits the funnel wall. Therefore, there is a risk that the ring nozzle clogs. This danger is increased by the fact that the cross section of the funnel decreases in the direction of its bend.
  • the suspension is not post-treated.
  • the invention has for its object to find a structurally simple device with which graphite-containing solid lubricants and a carrier liquid Mix to a homogeneous solid lubricant suspension.
  • the stability of the dispersion can be guaranteed over a longer period of time by the intensive mixer connected downstream of the dispersion unit.
  • Solid lubricants As a solid lubricant, those are used that to a significant extent contain graphite. Solid lubricants of this type are known, for example, from CH-PS 596 294 and CH-PS 609 728.
  • the suspension unit shown in FIG. 1 has a solid lubricant supply 1, a delivery device 2, an annular nozzle 3, a dispersing unit 4, an intensive mixer 6 and an agitator 7.
  • an inlet 8 for the solid lubricant At the upper part of the ring nozzle 3 is an inlet 8 for the solid lubricant and an inlet gap 9 for the carrier liquid arranged.
  • the inlet 8 for the solid lubricant is located above the inlet gap 9 for the carrier liquid.
  • the inlet gap for the carrier liquid 9 is provided to be adjustable. The amount and the film thickness of the carrier liquid film flowing along the walls of the ring nozzle 3 can thus be influenced.
  • the inlet for the solid lubricant 8 is via a suitable conveyor 2, e.g. a screw conveyor, fed from a storage container 1.
  • a suitable conveyor e.g. a screw conveyor
  • dispersing device 4 Commercially available devices which are able to exert a high shear force on the solid suspension can be used as the dispersing device 4.
  • an intensive mixer 6 which makes a further contribution to stabilizing the suspension.
  • a conveying device 5 e.g. Pump. This pump 5 is used to set the residence time of the suspension in the intensive mixer 6.
  • Suitable representatives of intensive mixers are e.g. Mixers with co-rotating or counter-rotating impeller shafts, agitator ball mills, jet mixers or screw mixers.
  • Another mixer 7 is connected downstream of the intensive mixer 6. This is equipped with a level control, which is able to switch the system on and off at the appropriate level.
  • the solid lubricant is fed via the conveyor 2 via the inlet 8 for the solid lubricant centrally into the upper part of the ring nozzle 3, falls down and is taken up by the carrier liquid film, which is formed by the inlet gap 9 for the carrier liquid, and then the Dispersing unit 4 supplied.
