Definitions

  • the invention relates to a cone screw mixer according to the preamble of claim 1.
  • a feature of this known screw mixer is that the holding device consists of a control flange bearing sealing elements on the spherical sealing body, the adjusting flange pressing the sealing elements onto the spherical sealing body by means of spring-loaded adjusting screws.
  • the essence of the known holding device is that frictional forces act on the spherical sealing body, which prevent the sealing body from rotating continuously.
  • the sealing body is prevented from rotating by the frictional forces and therefore only takes part in a wobbling movement, corresponding to the movement of the mixing screw, along a conical surface within the mixing container.
  • the spherical sealing body can wear out relatively quickly due to the frictional forces acting on it.
  • the spherical sealing body will nevertheless rotate with the shaft of the mixing screw because the frictional forces on the sealing body are reduced because of the oil content of the material to be mixed. This would have to be feared that the sealing body wears out relatively quickly.
  • the object of the invention is therefore to develop a conical screw mixer of the type mentioned at the outset in such a way that wear of the spherical sealing body is avoided with a structurally simple configuration of the holding device.
  • the invention provides the characterizing features of claim 1.
  • An essential feature of the invention is that no more frictional forces hold the spherical sealing body, but that the sealing body is held in a rotationally fixed manner by a pivot linkage extending from the housing with a universal joint arranged on the pivot linkage.
  • the spherical sealing body continues to take part in the wobbling movement of the mixing screw shaft without any frictional forces acting on it, the wobbling movement consisting of a tilting movement of the spherical sealing body, which is combined with an alternating tilting movement of the spherical sealing body.
  • the sealing body no longer participates in the rotation of the worm shaft, as a result of which signs of wear are avoided, in particular because no more frictional forces act on the sealing body.
  • the constant, non-rotating locking of the spherical sealing body it is possible to introduce lubricants and coolants into the bearing between the sealing body and the mixing screw shaft via flexible hoses. As a result, the life of the bearing is significantly extended and a high level of operational safety is achieved.
  • the lower end of the first swivel arm is rotatably mounted on the housing-fixed flange on a first swivel axis, that the upper end of the first swivel arm is connected to one end of the second swivel arm via a second swivel axis, the other end of which has a universal joint which engages with a transverse bolt on a bushing on the spherical sealing body.
  • the swivel linkage is made particularly simple, the two swivel arms ensuring the required stroke of the sealing body, corresponding to the tilting movement and the universal joint ensuring the inclination of the sealing body, which occurs in connection with the wobbling movement of the sealing body.
  • the length of the swivel arms is adjustable.
  • the swivel linkage can be adapted to different strokes of the sealing body if the entire arrangement is to be installed, for example, in a mixing container with differently inclined conical walls.
  • the universal joint consists of a bolt which is pivotally mounted on one end at one end in one direction on the axis at the end of the second swivel arm, and on the other hand on a cross bolt in the other direction at the other end is rotatably mounted, the cross pin engaging the bush on the spherical sealing body.
  • a mixing screw 70 is arranged in a mixing container 88 which tapers conically towards the bottom region and which rotates about the axis 110 at the speed n1 and which swivels about the container axis 100 along a conical surface at the speed n2.
  • the mixing screw 70 is arranged in its upper region at the free end of a guide arm 71 which is driven at a speed n2 via a motor 95 and a gear 72.
  • Corresponding seals 73 are provided on the container lid in order to prevent the product medium from escaping from the product space 80.
  • the bottom-side mounting of the mixing screw 70 takes place in the manner shown in FIGS. 2 and 3 with the aid of a universal joint 27, the mixing screw receiving its rotary drive (drive about the axis 110) via an articulated shaft 34, which is mounted in a hollow shaft 32 on the latter At the end of a lantern 62 is flanged, at the lower end of which the gear motor 65 attaches.
  • the mixing screw 70 is welded to a coupling piece 29 with an internal thread.
  • a screw-in bolt 1 is screwed in such a way that the thread automatically tightens during operation; d. H.
  • a right-hand or left-hand thread is used.
  • a rotationally fixed connection of the coupling piece 29 and screw-in bolt 1 can also be carried out with a feather key connection or a shear pin.
  • a bushing 2 is mounted on the screw-in bolt 1.
  • roller bearing 6 and the bushing 7 are attached to the screw bolt 1 without play by means of the circlip 8.
  • the screw-in bolt 1 is rotatably connected to the upper part of the universal joint 27 by means of screws 25.
  • the lower joint part is in turn screwed with screws 28 to the drive shaft 34 in a rotationally fixed manner.
  • a hemispherical sealing body 4 with recessed seals 3 is pushed over the screw-in bolt 1 with the bushing 2, the roller bearing 6, the bushing 7 and the circlip 8 and over the universal joint 27 and secured axially and radially by means of a flange 10 with a seal 9 and shim rings 5 .
  • Sealing takes place via the O-ring 56.
  • the screw connection takes place via the screws 59.
  • the bearings are relubricated via the blind screw 12 of the sealing disk 13 or via a constant supply of lubricant and coolant via a flexible hose, not shown, which instead the screw 12 is arranged.
  • An additional seal is ensured via the O-ring 11.
  • the construction and assembly must ensure that the center of the universal joint 27 and the center of the sealing bell 4 are one and the same point.
  • the mixing screw shaft can be inclined up to 25 ° to the vertical axis.
  • a bushing 31 (shaft sleeve) is rotatably mounted on the cardan shaft 34. Furthermore, the bearing inner rings of the bearings 36 and the tube 33 are drawn onto the cardan shaft 34 and secured with the circlip 38.
  • the cardan shaft 34 is provided with different centerings for the bearings and a threaded pin 46 with a square.
  • the bearing housing consists of a tubular housing 18, a counter flange 52 and a hollow shaft 32, which are welded together.
  • a plurality of assembly and control openings are arranged in the tubular housing 18 and are closed with a plurality of covers 21 arranged on the circumference of the bearing housing, the screws 60 and the sealing rings 19.
  • the outer rings of the bearing 36 are inserted into the hollow shaft 32 and are secured with the circlips 37 against axial displacement.
  • the bearing flange 43 and the double-acting axial bearing 40 are inserted into the hollow shaft 32.
  • the bearing flange 43 with the 0-ring 42 is now pushed into the bore of the hollow shaft 32 or over the outer ring of the bearing 40 and firmly connected to the hollow shaft 32 with the screws 60.
  • the bearing flange 39 must be in contact with the circlip 37 and the axial bearing 40 must be set axially with almost no play. Furthermore, the shaft sealing ring 30 and the lubricating nipple 58 are pressed into the hollow shaft 32.
  • the propeller shaft 34 is then inserted.
  • the drive shaft 34 is firmly connected to the thrust bearing 40 by means of the clamping disk 41, the spring ring 47 and the threaded nut 48.
  • connection of the mixing screw 70 with the screw-in bolt 1 is carried out by turning the square of the drive shaft 34, the coupling piece 29 screwing onto the thread of the screw-in bolt 1. This can be done without disassembling the bearing assembly. After performing this work, the bearing flange 43 is closed with the cover 45.
  • the bearing housing is rotatably screwed to the container bottom 17 by means of threaded bolts 55, nuts 54 and spring washers 53 and sealed with an O-ring 26.
  • the seal between the sealing body 4 and the container bottom 17 is with a Sealing flange 14, an adjusting flange 15 with O-ring 16 performed.
  • the material of the sealing flange 14 can be made of Teflon (registered trademark of DuPont) or another plain bearing material.
  • the material of the sealing body 4 must be made of stainless steel material or a hardened, plated or other material that matches the sealing flange 14.
  • the sealing flange 14 has an inner flushing ring 49, which is provided with an inlet or outlet bore, which is drilled through the adjusting flange 15.
  • the adjusting flange 15 is secured against rotation with a screw bolt with a lock nut.
  • a plurality of spring-loaded preload screws 24 with lock nuts 23 and the springs 22 are attached in the adjusting flange 15. These preload screws 24 press the adjusting flange 15 with the sealing flange 14 downward against the sealing surface of the sealing body 4.
  • the flushing ring 49 shown in FIG. 3 enables the sealing bell 4 or the sealing flange 14 to be cleaned without dismantling the bearing. Furthermore, this flushing ring 49 can be used as cooling for the sealing body 4.
  • the air space between the sealing flange 14 and the sealing body 4 and the bearing housing 18, 52, 32 can be regarded as an insulating layer.
  • the universal joint 27 and the sealing ball parts can be flushed from the inside with sealing liquid or cooling liquid or a gas. In this case, a connection is made for the inlet and outlet of the coolant in the cover 21.
  • the pivot linkage 50 shown in FIGS. 3 and 4 consists of a mounting plate 81 which is connected to the flange 20 fixed to the housing and in which the lower end of a pivot arm 82 is rotatably mounted via a first pivot axis 74.
  • the other end of the swivel arm 82 is articulated via a second swivel axis 75 to the one end of a second swivel arm 83, which in turn is in turn connected at its opposite, free end via the third swivel axis 76 to the free, front end of a bolt 84.
  • the bolt 84, with the pivot axis 76, is part of a universal joint 51 which, as a connecting part, establishes the connection to the underside of the sealing body 4.
  • the bolt 84 is rotatably mounted on a cross bolt 86, the cross bolt 86 passing through a bushing 85.
  • the socket 85 is firmly connected to the underside of the sealing body 4.
  • a sealing flange 78 on the housing side is arranged opposite the sealing flange 14 and is fastened to its bearing flange 77.
  • FIG. 4 shows the corresponding inclinations of the sealing body 4 during the wobble movement, the bushing 85 then taking up its positions 85 'and 85 ".
  • the described pivot bearing of the sealing body is a significant advantage over the prior art, because previously the frictional forces between the sealing body and the sealing flange 14 had to be always greater than the frictional forces caused by the roller bearings 6 and the seals 3 and 9, so that the spherical Seal body 4 was exposed to wear.
