Definitions

  • the invention relates to a device for mixing and homogenizing at least two media, with a boiler, on the bottom of which a homogenizer having a rotor which can be rotated about an axis and a stator is arranged, the device being in a first operating position in which the mixture located in the boiler in inline operation from the boiler through the homogenizer to the lower boiler section, at least to switch to a second operating position in which the mix in the boiler circulates out of the boiler the homogenizer must be returned to the upper section of the boiler or drained via a bypass line.
  • the homogenizer is preferably installed in the center of the bottom of the mixing or stirring vessel referred to as the kettle, the homogenizer - i.e. the rotor rotatable about the longitudinal axis by means of a drive and the stator fixed relative to the axis of rotation - for homogenizing the Mixed material in in-line operation is raised so far by means of a suitable adjustment device that the homogenizer protrudes so far inward beyond the actual boiler bottom that the stator outlet openings above the boiler bottom are free.
  • the homogenizer at ' is lowered the known apparatus by means of the setting means that its outlet openings - more precisely, the outlet openings of the stator - so far below the bottom of the boiler that they are connected to the bypass line, so that the mix or the like, depending on the selected setting of a valve arranged in the bypass line. can either be returned to the boiler via the pumping section of the bypass line or can be drained from the device.
  • the effort to be made for an axial adjustment of the entire homogenizer requires considerable effort, especially since relatively large adjustment devices with corresponding adjustment forces are required for the adjustment, because they are moved from the second to the second First operating position not only move the mass of the homogenizer and the drive connected to it, i.e. including the motor, but also have to counteract the pressure in the boiler that acts on the homogenizer.
  • this adjusting force must be constantly maintained in the first operating position, so that, for example, the corresponding hydraulic unit must be constantly switched on during operation in the first operating position during hydraulic operation.
  • the present invention has for its object to improve the known device of the type described above while avoiding its disadvantages so that while reducing the overall height of the effort to be adjusted from the first to the second operating position due to smaller masses to be adjusted and in particular smaller counterpressure forces or due to the compressive forces supporting the seal, while at the same time avoiding dead spaces within the boiler.
  • a control ring which is axially adjustable by means of an adjusting means relative to the homogenizer and is designed in the manner of a slide, is arranged radially outward of the homogenizer, which in a first operating position has a first annular control surface and a first housing surface parallel to it releases from the homogenizer into the boiler first channel, while it lies sealingly with a second annular control surface on a parallel to this second housing surface, and in a second operating position with its first control surface sealingly against the first housing surface and between its second control surface and the second housing surface forms a second channel into which the bypass line opens.
  • the homogenizer is preferably arranged stationary in the axial direction, namely below the bottom of the boiler, which is accordingly provided with a central feed opening opening into the rotor of the homogenizer.
  • adjustable control ring is preferably cylindrical on its radial outside and guided in a cylindrical section of the housing, the control surfaces of the control ring preferably running obliquely to the vertical, namely the first control surface expediently from a central section of its inside to the outside or to its top, and the second control surface opposite to this.
  • control ring between the first operating position and the second operating position can be releasably locked in a third operating position.
  • FIG. 1 shows, in a simplified partial representation, a central vertical section through a stirring device 1 according to the invention, that is to say a device for mixing and homogenizing at least two media, which has a kettle 2, of which only the lower section is shown in FIG.
  • the top is provided with a cover, not shown, on which various units, such as the agitator, etc., are arranged.
  • a homogenizer generally designated 4, which has a rotor 7 rotatable about the vertical axis 6 by means of a drive (not shown) and a stator 8 arranged in a rotationally fixed manner.
  • the homogenizer is in the axial direction, i.e. So arranged in the direction of the vertical axis 6, stationary.
  • a control ring 11 (Fig. 2/3) which is axially adjustable relative to the homogenizer 4 in the direction of the double arrow 9 (FIG. 3) is arranged by means of an adjusting means, not shown, such as a small hydraulic cylinder, which is designed in the manner of a slide.
  • the control ring 11 is cylindrical on its radial outside 12 and axially guided in a housing section 13 with a cylindrical inside.
  • the radially inner side of the control ring 11 has an approximately central cylindrical section 14, from which a first control surface 16 extends obliquely to the vertical towards its upper side 17.
  • a second control surface 18 of the control ring 11 runs from its cylindrical, central section 14 in the opposite direction to the first control surface 16, that is, obliquely to the vertical downward towards a cylindrical lower section 14 'of the control ring.
  • the boiler bottom 3 has an opening 19 in its center, the diameter of which on the side facing the rotor 7 corresponds to the inside diameter of the rotor 7, and which widens conically on the side facing the boiler 2 by an unrestricted intake area for to create the goods to be homogenized in the homogenizer 4.
  • the boiler bottom 3 has an inclined annular surface 21, referred to above and below as the first housing surface, which runs parallel to the first control surface 16 of the control ring 11.
  • a corresponding second housing surface 22 assigned to the second control surface 18 of the control ring 11 is arranged on the upper edge of a housing part 23 shown in block form and therefore runs parallel to the second control surface 18.
  • the outside of the upper section of the housing part 23 is at a distance a from the inside 14 'of the lower section of the control ring 11 and thus creates an annular channel 24 into which a bypass line 26 opens, which is shown in FIG. 1 only with its mouth section and thence leads past the outside of the boiler into the upper section of the boiler.
  • the control ring 11 is in the first operating position, in which its first control surface 16 and the first housing surface 21 parallel thereto are one from the homogenizer 4 or its stator 8 into the boiler 2 leading or opening annular first channel 27, while the control ring 1.1 with its second control surface 18 sealingly abuts the second housing surface 22.
  • the pressure exerted on the top 17 and the obliquely running first control surface 16 of the control ring 11 acts in a sealing manner with respect to the surfaces 18 and 22 which abut one another and thus contributes to closing the bypass line 26, so that the device is in the first operating position 1 works in inline operation, the mixture therefore circulating according to the arrows 28 from the boiler 2 through the homogenizer 4 back into the boiler 2.
  • FIG. 2 shows the stirring device 1 in the second operating position, with a smaller cut-out sufficient for this than the illustration according to FIG. 1 being chosen.
  • the first control surface 16 of the control ring 11 and the first housing surface 21 of the boiler bottom 3 abut one another, while the second control surface 18 of the control ring 11 and the second housing surface 22 are spaced apart from one another to create a second annular channel 29, whereby the bypass line 26 opens into the second channel 29, so that the mix in the direction of arrows 30 from the boiler through the rotor 7 and the stator 8 of the homogenizer enters the second channel 29 and from there into the bypass line 26 , by means of which the material to be mixed is either returned to the upper section of the boiler in what is known as circulation operation, or, if a valve, tap or the like, which is not shown, is arranged in the bypass line and is switched accordingly. can be drained from the device 1.
  • FIG. 3 of the drawing shows a representation according to FIG. 2, in which the control ring 11 is in a middle third operating position lying between the first operating position (FIG. 1) and the second operating position (FIG. 2), so that the mix can return from the boiler through the homogenizer 4 'both in throttled inline operation according to the arrows 28 into the boiler 2 and, due to the prevailing negative pressure in the boiler 2, additional products can be sucked in according to the arrows 30, Fig. 3.
  • the overpressure usually present in the boiler 2 also has a favorable effect on the respective operation in the second and third operating positions. Because in the second operating position (FIG. 2), the surface of the control ring 11 which is acted upon by the pressure, that is to say its second control surface 18 and its underside 25, is larger than its upper side 17, so that a resulting pressure in the sealing direction also results in this operating position .
