Definitions

  • the invention relates to a mixer for plastic preparations with a cylindrical mixing container with a vertical axis, an agitator shaft arranged on the axis of the mixing container, which carries mixing blades and extends through the bottom of the container, and with a drive device for the agitator shaft below the bottom of the container.
  • the object of the invention is such a design of a mixer of the type mentioned that the inner walls of the mixing container and the mixing tool can be easily cleaned.
  • the agitator shaft is designed as a hollow shaft, that a support rod for the mixing blades can be displaced in the vertical direction within the hollow shaft and that a drive device for displacing the support rod is connected to the lower end of the agitator shaft outside the bottom wall .
  • the invention enables the mixing tools to be completely lifted out of the interior of the mixing container, since the length of the hollow shaft is dimensioned accordingly.
  • the interior of the mixing container can be cleaned completely unhindered.
  • the mixing tools can both from the top and can also be cleaned from the bottom. The invention thus brings a surprising solution to the cleaning problems.
  • the invention provides that the hollow shaft designed as a cylinder chamber receives a piston rod which carries a support sleeve for the mixing blades which overlaps the hollow shaft, and that a stuffing box-type rotary connection is provided at the lower end of the agitator shaft to introduce a pressure medium.
  • This embodiment enables the mixing tools to be raised particularly advantageously. This is because the cylinder chamber and the piston rod are used as a pressure medium unit.
  • the cylinder chamber extends into the part of the agitator shaft which extends through the bottom wall and that the length of the piston rod is correspondingly greater than the height of the mixing container.
  • This embodiment of the invention provides a large lifting height for lifting the mixing tools, so that the mixing tools can be completely removed from the interior of the mixing container.
  • the drawing shows a double-walled mixing container 1 in the form of an upright cylinder.
  • the upper edge of the mixing container 2 is closed by a cover 3 for which an actuating device 4 is provided, e.g. as a pressure medium actuating device.
  • an agitator shaft 5 which extends through the bottom wall 6 in a conventional manner and is supported in a bearing receptacle 7 below the bottom wall.
  • a drive hub 8 receives a drive wheel which is driven by a motor via a transmission or a belt drive.
  • the agitator shaft 5 comprises a hollow shaft 9, which enables the mixing tool to be removed completely.
  • the hollow shaft 9 preferably extends approximately to the height of the upper edge of the mixing container 2.
  • a support rod or piston rod 10 is guided within the hollow shaft 9.
  • a seal 11 is provided, so that this arrangement forms a pressure medium unit with a cylinder chamber 15.
  • a gland-type rotary connection 12 is arranged, the pipe socket 13 of which, via a control device, for example a valve, ver with a pressure medium source, not shown is binding.
  • a connecting line 14 leads to the cylinder chamber 15 within the hollow shaft 9.
  • the piston rod 10 carries at its upper end a support sleeve 16 which is formed in the manner shown from individual segments 17, 18, 19, 20. These segments have a central passage which overlaps the hollow shaft 9. The segments are connected to one another and partly also serve as hub parts for mixing blades 21, 22, 23, which are designed in a manner known per se. At the upper end of the support sleeve 16, a cover scraper 24 is also provided.
  • the illustration of the figure shows the working position of the mixer in solid lines.
  • the lid 3 is closed and the support sleeve 16 with the mixing blades 21, 22, 23 and the lid scraper 24 is located in the interior of the mixing container 1.
  • the mixing container can be charged via openings in the lid 3, not shown in detail.
  • the discharge device is also not shown.
  • the mixing process takes place in a known manner by rotating the agitator shaft 5.
  • the lid 3 When the mixing container is to be cleaned, the lid 3 is raised and pivoted into the open position 3 'shown in dash-dotted lines. Pressure medium, e.g. Compressed air, so that the piston rod 10 is extended.
  • the piston rod 10 with the support sleeve 16 can be raised to the position 10 'or 16' shown in dash-dotted lines.
  • the mixing tools are completely lifted out of the interior of the mixing container 1.
  • both the mixing tools and the interior of the mixing container are freely accessible, so that complete and comprehensive cleaning is possible.
  • the mixing blades can be brought into the cleaning position in a simple manner by introducing pressure medium. Mechanical connections cannot be broken. The invention thus brings about a considerable improvement for the cleaning processes on a mixer.
