Definitions

  • the invention relates to a screw press according to the preamble of claim 1.
  • the drive tube 6 is formed in one piece and of an unfavorably great length because the lower part 10, 13 is of an unfavorably great height.
  • An upper bearing of the spindle body 1 is not disclosed.
  • the lower bearing 8 is located very deeply below the spindle body 1 at the lower end of the lower part 10, 13 and is connected to a bearing collar 7 fastened approximately at the longitudinal center of the drive tube 6.
  • the upper half of the drive tube 6 is loaded not only by the drive torques, but also by changing axial forces from its own weight and the operation of the press spindle together with the material to be pressed out. At least that upper half must therefore be designed accordingly more complex.
  • the clearing vanes 23 are attached to the drive tube 6.
  • the collection and discharge of the squeezed-out liquid in the lower part 10, 13 in two axially spaced planes 27, 28 and 31, 32, 33 as well as the collection and discharge of the pressed material in a third height plane 22 are unfavorable and require increased structural complexity , 23.
  • the transmission gear 5 of the drive device is additionally held against rotation. 'Repairs, assembly and maintenance on the entire lower press area from the transmission 5 to the spindle body 1 are complicated and expensive.
  • the invention has for its object to facilitate maintenance, assembly and repair on the press area below the upper part of the housing, and to reduce the stress on the drive device and the drive tube.
  • the top tube can be intercepted particularly easily in its telescopic lowest position.
  • the drive bearing can e.g. B. be designed as a robust ball slewing ring.
  • the drive connector can carry a ring gear with which at least one pinion of an associated drive of the drive device meshes.
  • a particularly reliable embodiment is one in which the pinion is overhung on the associated drive.
  • raceways preferably extend over the entire circumference of the drive tube, so that the crane has a working angle range of 360 °.
  • the measures of claim 6 protect the tracks and the running gear of the crane when it is not needed.
  • the crane can e.g. B. pulled up into its rest position on the lower part of the housing.
  • the lower bearing is easily accessible for all 'purposes and can be accommodated constructively.
  • the special arrangement of the lower bearing reduces the length of the press spindle to a minimum.
  • the top tube can be mounted completely free of the lower bearing with respect to the bottom socket of the spindle body.
  • the structure according to claim 8 is simple, easily accessible from all sides and reliable.
  • the drive device can be arranged on the floor or under the floor and is easily accessible in all cases.
  • the features of claim 9 lead to a skillful collection and derivation of the squeezed out liquid which has penetrated into the spindle body.
  • the bottom of the ring channel can be inclined towards the outlet connection to facilitate the drainage of the liquid. In the borderline case, only such an outlet connection could also be provided.
  • the features of claim 10 offer on the one hand the opportunity for maintenance personnel to get through the opening and, on the other hand, emergency drainage in the event that a jam of squeezed liquid should occur inside the spindle body. In this case the liquid would penetrate through the labyrinth gap seal and drain through the drive tube and a drain in the foundation.
  • the squeezed liquid is taken care of on the one hand from the upper part of the housing and on the other hand from the press spindle.
  • the bottom of the second ring channel and the third ring channel is inclined towards the drain openings in order to achieve a faster and complete drain of the squeezed out liquid.
  • the lines according to claim 13 are used first of all for emergency drainage of the second and third ring channels in the event that the level of the squeezed liquid should rise too high therein. This can occur in particular when the screw press is started up.
  • the lines serve as metering lines for introducing a foam inhibitor into the second and third ring channels in the event that foam formation should occur within the screw press due to the relatively high drip height of the squeezed-out liquid.
  • the lines are open towards the bottom, so that no squeezed-out liquid flows down from above.
  • an effective device for discharging the pressed material from the lower part of the housing is created in a confined space.
  • a very effective filling area of the screw press is created.
  • the material to be pressed can be introduced into the annular space in any manner known per se.
  • the upper bearing can be easily and safely centered relative to the housing.
  • the upper bearing can e.g. B. have a spherical roller bearing. Its arrangement on the upper part brings a relatively low overall height of the entire screw press.
  • Fig. 1 shows an upright screw press 1 for squeezing liquid from sugar beet chips.
  • the screw press 1 has a circular cylindrical upper part 2 of a housing 3.
  • the housing 3 also includes a lower part 5 which is screwed to the upper part 2 along a plane 4 and which in turn is screwed along a plane 6 to a stand 7 which is anchored in a foundation 8 on a floor 9.
  • a cover 11 is screwed along a plane 10, which is provided radially further inside with manholes 12 and further outside with observation openings 13.
  • the cover 11 carries in its center an upper bearing 14 designed as a spherical roller bearing for a stub shaft 15 of a press spindle 16.
  • the cover 11 is surrounded by a peripheral railing 17.
  • the press spindle 16 is rotatably supported at the bottom in a lower bearing 19 of the lower part 5 in the form of a rotary bearing connection and can be driven in a rotating manner in a manner to be described later by means of a drive device 20 arranged at the bottom in the stand 7.
  • the upper part 2 of the housing 3 has a spray jacket 21 which is divided into axially successive shots and a screen jacket 22 which is arranged within the sprint jacket 21 and is likewise divided into axially successive shots. Between the spray jacket 21 and the screen jacket 22, an annular space 23 is provided for draining liquid, which is pressed out of the sugar beet chips and penetrates through the screen jacket 22 to the outside through screen holes (not shown).
  • the sieve jacket 22 is provided with such sieve holes over its entire effective axial length.
  • the outer surface of the sieve jacket 22 rests on support rings 24 which are axially spaced apart and which are in turn held by comb plates 25 which run axially parallel and are spaced apart from one another in the circumferential direction and are fastened to an inner surface of the spray jacket 21 (cf. also FIG. 5).
  • retainers 26 are inserted from the outside into receiving openings in the upper part 2, which extend radially inwards into the vicinity of a spindle body 27.
  • the radial extent of the retainers 26 decreases from top to bottom in the same way as the cross-sectional area of the spindle body 27 increases from an upper inlet side 28 to a lower outlet side 29.
  • the annular space 23 is connected to a drainage device 30 in the lower part 5.
  • An upper end region of the spindle body 27 is surrounded at a radial distance by a fifth ring wall 31, which is fastened to the screen jacket 22 via outer web plates 32 (cf. FIG. 5).
  • a fifth ring wall 31 which is fastened to the screen jacket 22 via outer web plates 32 (cf. FIG. 5).
  • an annular seal 33 is provided which prevents penetration of the material and liquid to be squeezed out into a wedge-shaped annular space 34 between the upper end region of the spindle body 27 and the fifth ring wall 31. Details of the ring seal 33 are shown in FIG. 4.
  • An annular space 35 between the screen jacket 22 and the fifth ring wall 31 serves to receive the material to be squeezed, in this case the wet chip, and is sealed at the top by an annular plate 36.
  • a working platform 37 is attached which extends over approximately one third of the circumference (cf. FIG. 2).

  • the base 41 has outlet nozzles 46 arranged on a circle concentric with the longitudinal axis 45 of the spindle press 1.
  • Annular channel 40 truncated cone-shaped sheets 47 and 48 are used, which supply the pressed-out liquid collected in the first annular channel 40 to the outlet connection 46.
  • the ring 42 is closed at the top by a cover 49.
  • the cover 49 has an opening 51 which is closed by a closure 50 via a labyrinth gap seal (cf. FIG. 6).
  • the opening 51 serves on the one hand as a manhole and on the other hand as emergency drainage in the event that a jam of squeezed liquid should occur in the interior 39.
  • This liquid then overcomes the labyrinth gap seal between the closure 50 and the opening 51 and flows downwards through the bottom socket 43 and a drive tube 52 flanged to its underside and further through a corresponding central opening 53 of the drive device 20 until this liquid finally flows into a drain 54 of the foundation 8 arrives.
  • Manholes 55 are provided in the spindle body 27 at the top. Below the ring seal 33, the spindle body 27 carries a plurality of compressor blades 56 distributed over the circumference in a horizontal plane, which lead to a pre-compression of the material to be pressed.
