Definitions

  • the invention relates to a dry mortar mixing system according to the preamble of claim 1.
  • Such dry mortar mixing plants have been known for a long time and include a conveying and a downstream mixing chamber.
  • a silo at the front end of the dry mortar mixing system via a vertical nozzle Can be connected as a storage container for the dry mortar, via which the mix flows vertically down into the first feed channel and is transported there via a screw conveyor in a feed pipe to the downstream mixing channel.
  • the water can then be added to the mixing channel itself, so that the finished mix can finally be removed in the mixing chamber.
  • the conveyor shaft provided with the screw conveyor and the downstream mixer shaft carrying the mixing blades are plugged into one another at the end face via a connecting piece, so that the conveyor and mixing shaft rotate together.
  • the object of the invention is therefore to overcome the disadvantages of the prior art and to improve a dry mortar mixing plant of the type mentioned in such a way that the total service life is significantly increased compared to the prior art and, moreover, an easier and faster introduction and Removal of all parts, for example, for cleaning and replacement is guaranteed.
  • the object is achieved according to the features specified in the characterizing part of claim 1.
  • Advantageous embodiments of the invention are specified in the subclaims.
  • the dry mortar mixing plant according to the invention achieves significant advantages over the prior art. Firstly, the total life of the Mischan was many times higher than the prior art, since the described wear and abrasion effects, in particular between the screw conveyor and the surrounding delivery pipe, are avoided by the arrangement according to the invention. This results from the fact that the screw conveyor at the transition from the conveying part to the mixing part is guided at its front end in a bearing additionally arranged there, and the material to be conveyed is no longer fed into the conveying opening via an axial one but in the bottom of the conveying chamber subsequent mixing chamber is dispensed. As a result, the vibrations can be significantly reduced.
  • the essential advantage is also achieved that the distance between the outer edge of the screw and the surrounding conveyor tube can be more than 3 mm, preferably 4 to 10 mm and more. This is therefore possible that the conveyor tube no longer has to serve as a centering device to limit the vibrations, so that it is reliably ensured that the outer edge of the screw conveyor no longer strikes the conveyor tube. In particular, this dimension also enables dry discharge without technical problems.
  • a common bearing is provided at the front end of the conveyor tube for the mixing shaft and conveyor shaft arranged one behind the other in the axial direction, the coupling according to claim 4 being effected via a coupling hub.
  • a simple technical possibility for installing and removing the delivery pipe is provided, which is mounted axially extendable in the outer casing, for which purpose in a further development according to claim 6 at least two axially spaced apart and on the outer casing fixed radial holding devices are provided.
  • the simple installation and removal of the delivery pipe also results from the fact that the holding device facing the bearing is provided with a centering flange which comes into contact in a corresponding annular fold of the holding device, but the inner circumference of the holding device is contactless ends in front of the outer casing of the delivery pipe. Therefore, the feed pipe can be easily axially inserted into its installed position in the axial direction, and finally precisely adjusted via its flange.
  • the bearing 19 further includes a connecting hub 21, in which the front end of the conveyor shaft 11 engages in a corresponding bore 23.
  • outlet opening 27 In front of the end 25 of the conveying channel 1 receiving the bearing 19 there is an outlet opening 27 at the bottom for the material to be conveyed and mixed, the outlet opening 27 being arranged between the holding and centering device 7b and the end end 25.
  • the mixing shaft 29 is also guided at the end facing the delivery channel 1 in the connecting hub 21 and at the opposite end 35 in a front bearing 37 arranged there. About a before the outlet channel 39 attached to the front end 35, the mix is discharged downwards.
  • the mix is fed via the mentioned and not shown silo container to the delivery channel 1 via the attachment flange 5.
  • the conveyor shaft 11 is set in rotation via the motor 5, so that the mix is conveyed further via conveyor vanes 41 below the attachment flange 5 into the conveyor tube 9.
  • Due to the rotation of the screw conveyor with the delivery pipe 9 arranged in a rotationally fixed manner the material to be mixed is transported further through it and is discharged at its front end in front of the bearing 19 through the lower outlet opening 27 into the subsequent mixing chamber or the mixing channel 3, the lower wall of the mixing channel 3 is arranged lower than the corresponding lower wall of the delivery pipe 9.
  • the delivery pipe 9 is installed axially symmetrically to a surrounding outer jacket 43, which at the same time represents the outer wall of the mixing channel 3.
  • the conveying channel 1 with the conveying shaft 11 represents a metering device for the uniform feeding of mixed material.
  • the mixing shaft 29 is driven via the connecting hub 21 together with the screw conveyor, the material to be mixed being conveyed, if necessary, with the addition of water via the water inlet connector 33 to the front end 35 of the mixing channel 3 and then being discharged via the outlet channel 39.
  • short blades 31a are also provided for the further transport of the conveyed material, which are connected to an adjacent one on the mixing shaft 29 seated transport and mixing vanes 31 are attached and encircle the part of the delivery pipe 9 which projects into the mixing channel 3.
  • the conveying shaft 11 and the mixing shaft 29 are not only held and guided securely not only at their outer end, but also jointly at their mutually facing end via a common bearing 19. This significantly minimizes the shrinkage of the entire arrangement. Since the conveyor tube 9 thus also no longer has to assume a centering function for the screw conveyor 13 and the conveyor shaft 11, it is possible for the outer edges 45 of the conveyor screw 13 to end at a distance 46 from the inside of the conveyor tube 9. The distance can be more than 3 mm, preferably 4 to 10 mm and, if necessary, even more. A jamming of sand grains and the grains, in particular in the so-called dry discharge between the outer edge 45 and the inside of the conveyor tube 9, is thereby reliably avoided. Furthermore, this ensures a completely uniform metering of the mixture to be supplied, so that the mixture discharged at the outlet 39 always has the same mixing ratio with the water supplied.
  • the delivery pipe 9 can also be easily removed if necessary after screws 57 are removed, via which a centering flange 59 welded to the outer circumference of the delivery pipe 9 is firmly connected to the second holding device 7b.
  • the holding device 7b ends at a distance from the outer circumference of the delivery pipe 9, so that the delivery pipe 9 can be easily installed or removed in the axial direction from the mixing chamber by this holding device 7b.
  • the delivery pipe 9 is centered via the centering flange 59, which comes to rest in an appropriately dimensioned annular fold 61 of the holding device 7b in the installed state.
  • the first holding device 7b is merely designed as a pipe socket 63 welded to the inside of the outer jacket 43 for further centering.
  • the connecting hub 21 is provided on the end face with at least one radial groove 53, into which corresponding drivers 55 of the mixing shaft 29 or the conveying shaft 11 are inserted by being pushed axially into one another. This ensures the common rotation from the drive unit 15 to the mixing shaft 29.
  • the delivery pipe 9 at the end facing the motor 15 is likewise axially essentially non-displaceable in a shaft journal 17 and the mixing shaft 29 is also secured against axial displacement at its opposite end 35 in a manner not shown, no further is required technical measures to prevent that the connecting hub 21 is not axially displaced, since this is automatically and automatically centered by the inserted driver 55 on the conveyor and mixing shaft.
  • the outer jacket - as shown in the figure - can also be divided into two, with a split in the area of the holding device 7b. By loosening a quick-release fastener 58, the outer jacket can then be removed in the area of the mixing shaft when the mixing shaft 29 has already been removed lower by a lower swivel bearing 59.
