Definitions

  • the invention relates to a mixer according to the preamble of patent claim 1.
  • both the swivel arm is rotatably driven from above. Furthermore, at the free front, rotatable end of the swivel arm housing, there is another gear housing, in which a reduction gear is arranged, with which the upper part of the mixing worm shaft together with the mixing worm shaft bearing is driven to rotate continuously on a circular path.
  • the mixing screw in turn, is driven in rotation by a drive arranged below the mixing container.
  • the object of the present invention is to develop a mixer with a mounting of the mixing screw in such a way that the mixing screw shafts are supported in a substantially reliable manner in the product space.
  • the invention is characterized in that the mixing screw shaft is held axially displaceably in the bearing at the free, rotatable end of the swivel arm, and in that the swivel arm has no built-in gears.
  • An essential feature of the present invention is therefore that the axial longitudinal dimensions of the mixing screw shaft are accommodated directly in the swivel arm by a bearing of the mixing screw. This means that the lower bearing of the mixing screw is no longer stressed and the entire arrangement has a longer service life.
  • the swivel arm itself has no gear internals, i.e. So that a rotary drive of the upper bearing of the mixing screw shaft is omitted according to the invention, so that the swivel arm is equipped without gear internals. This avoids complicated and fault-prone gear parts, bushings and seals, which significantly increases operational safety.
  • the two above-mentioned features also add up to one another in that the operational safety of a mixer according to the invention is significantly improved, since axial changes in the length of the mixing screw shaft no longer lead to a load on the bearings of the mixing screw shaft and complicated gear assemblies for the swivel arm are avoided.
  • the upper bearing of the mixing screw shaft is designed as a thru-axle, which means that the bearing of the mixing screw shaft in the swivel arm consists of a bushing which is open in the axial direction of the mixing screw shaft and into which a spherical bushing which is fixedly attached to the mixing screw shaft engages and is axially displaceable on the inner wall of the swivel arm-fixed bushing.
  • the mixing screw shaft-side bushing is spherical, changes in the angle of the mixing screw shaft are also possible without stressing the swivel arm-side bearing.
  • the bottom bearing is a hemispherical bottom seal through which the mixing screw shaft extends and is mounted in a universal joint beyond the bottom opening.
  • the hemispherical sealing element is located in a housing-fixed Teflon glass fiber or Teflon-carbon sealing ring.
  • This sealing ring is preferably preloaded and has an automatic adjustment. At the same time there is a connection option for a purge gas line and a connection option for a pressure compensation system. This enables a function check during operation through appropriate inspection openings, and all lubricated parts are outside the product area.
  • the product space 2 is defined by a conical mixing container 1, in which a mixing screw 3 is mounted on a mixing screw shaft 4 and runs along the inside of the conical wall of the product space 2 by rotating a swivel arm 5.
  • the swivel arm 5 is in this case sealed and transferred to the outside via a housing flange 6 into a shaft 7, which in turn is connected to a gear 8.
  • the gear 8 is driven by a drive motor 9, the swivel arm 5, for example, making 5 revolutions per minute along the inner wall of the mixing container 1.
  • the bottom-side mounting of the mixing screw shaft 4 takes place in that it is guided through the container bottom 19 in a sealed manner and is mounted in a universal joint 10 below the container bottom 19.
  • the mixing worm shaft 4 is driven from below via the drive motor 13 located below, which works via a lantern 12 and a hollow shaft 11 on the drive shaft 27 (FIG. 2) of the universal joint 10.
  • FIG. 1 Another major advantage of the simple design of the swivel arm 5 is that, according to FIG. 1, it is now possible to introduce a nozzle pipe 17 into the product space 2 centrally through the shaft 7 and through the straight part of the swivel arm 5, with which it is possible to use a spray jet To give 1 8 to the product.
  • FIG. 2 shows further details of the mixing container shown in FIG. 1.
  • the swivel arm-side bearing consists of a thru axle 20 which is connected to the mixing screw shaft 4 in a rotationally fixed manner.
  • the bottom bearing is formed by the above-mentioned universal joint 10, wherein the mixing screw 4 is connected to a screw-in bolt 30, which is part of the universal joint 1 is 0.
  • the other part of the universal joint 10 is continued in the drive shaft 27, which is coupled to the drive motor 13 (FIG. 1) via a corresponding gear.
  • the sealing of the mixing screw shaft 4 in relation to the tank bottom 19 takes place via a hemispherical sealing element 14 which is firmly connected to the mixing screw shaft 4.
  • a sealing ring 15 is arranged on the housing side, which is preloaded and has an automatic readjustment.
  • a purge gas line and a pressure compensation system can be connected to this sealing ring.
  • the function is checked via a control sight glass 26.
  • the lower part of the universal joint 10 is formed by a drive shaft 27 which is guided downwards to the drive motor 13 via a hollow shaft 11.
  • the mixing worm shaft 4 is connected at its upper end to a thru-axle 20, on the outer circumference of which a spherically shaped bushing 34 is seated, which is covered at the top by a disk 35 which is fastened with a screw 36 in the thru-axle 20.
  • the housing-side storage takes place in that the spherical bushing 34 rolls on the inner circumference of a bushing 32, which in turn is arranged in the inner circumference of a pipe section 28.
  • the top surface of the pipe section 28 is formed by a cover 33 which is fastened with a screw 38. The fastening of the cover with the pipe section is carried out using screws 29.
  • the pipe section 28 is connected to one end of a shaft 25, the other end of which ends in a shaft 24 of smaller diameter, this shaft 24 engaging in the inner circumference of the end face of a hollow shaft 22 and being fastened there.
  • the other end of the hollow shaft 22 is connected to a cover plate 23 and opens into a flange 21 which is connected to an opposite flange 60 of the swivel arm drive by means of associated fastening screws 61
  • the flange 60 is in turn connected to the shaft 7, which is connected via a feather key 44 to a hollow shaft 42, which in turn has external teeth and is part of the transmission 8
  • the end of the shaft 7 is terminated by a washer 47 and a screw 45 which fastens the washer 47 to the end of the shaft 7.
  • the shaft 7 is sealed in the housing flange 6 of the mixing container by means of a stuffing box packing 53 which is designed to be self-adjusting.
  • a flange 51 which is penetrated by threaded bolts 70, which on the one hand are screwed into an associated flange 52 fixed to the housing and on the other hand penetrate corresponding bores in the flange 51 and on the opposite side with springs 71 and nuts above, presses on the face of the stuffing box packing 53 72 are supported.
  • the stuffing box packing 53 lies on the outer circumference of a protective sleeve 55, which is connected to the shaft 7 in a rotationally fixed manner.
  • the entire stuffing box packing 53 is connected by means of screws 67 to a flange 56 fixed to the housing, which in turn is connected to a flange 57 of larger diameter, which in turn is seated on a gear flange 59 of the housing via a corresponding plating 58
  • the bushing 34 is spherical on the outer circumference and cylindrical on the inner circumference.
  • the reason for the spherical design of the outer circumference of the bushing 34 is that the bushing 34 can deflect laterally in the event of changes in length or in the event of canting or overloading of the mixing screw shaft 4 and therefore a breakage of the bushing 3 4 does not occur so easily.
  • the bushing 34 is made of AMCO steel; this is a self-lubricating, highly wear-resistant steel. The lubrication of the bushing 34 takes place here via residual moisture in the product space 2 sensitive mixed product and the mixed product itself
