Definitions

  • the invention relates to an agitator, in particular in the form of an impeller, consisting of an agitator hub with a plurality of agitator arms for attachment to the agitator shaft for the mixing of substances in agitating vessels, in particular those which tend to cake, encrustation and / or polymerization.
  • Stirrers are used for the exchange of materials in fluid media, which can change from the liquid to the disperse or pasty state.
  • Stirring elements of various shapes are known. So there is e.g. Mixing elements in anchor form, impeller form, according to DIN 28144, page 13, and in propeller form.
  • the stirring elements can be in one piece or must be in several parts. This in turn depends on the permissible or economical diameter of the mixing vessel cover.
  • a one-piece stirring element can always be installed in a mixing vessel with a vessel lid diameter equal to the vessel diameter. If the agitator used, enamelled or bare, has a reduced diameter, the assembly opening, i.e. the vessel lid, are reduced in relation to the vessel diameter. However, this reduction of the lid diameter is not sufficient for some processes, so that ultimately an assembly lid diameter is selected that requires a multi-part stirring element.
  • the invention relates to such a multi-part stirrer, in particular in bare design and in impeller form.
  • This stirrer can be divided, i.e. disassembled, brought into the mixing vessel through a relatively small assembly opening and assembled there and onto the stirrer shaft.
  • Multi-part, at least two-part stirring elements are known, in particular in the form of impellers, e.g. three stirring arms as a single-arm piece and as a two-arm piece, each with half a hub part, are introduced individually through the small assembly opening into the mixing vessel and then screwed onto the stirrer shaft. You get a multitude of sharp edges and a multitude of gaps between the individual components. The sharp edges and gaps are the starting point for caking, incrustation and / or polymerisation of fluid media.
  • the invention has for its object to design a multi-part agitator for a mixing vessel with a small mounting opening so that it is gap-free after installation.
  • the agitator 1 shown in Fig. 1 consists essentially of the agitator hub 2, which can be attached and attached to an agitator shaft, not shown, in a known manner. From this stirrer hub 2, the stirrer arms 3 extend outwards in a 120 ° division. Two of these stirrer arms 3 are always connected to the stirrer hub.
  • the third stirrer arm is reproducibly mountable and detachably attached to the stirrer hub 2 according to the invention.
  • the stirrer arm 3, which according to FIG. 2 consists of the two stirrer arm bars 4 and according to FIG. 3, the two stirrer arm webs 5, was divided into the stirrer arm stub 6 and the rest of the stirrer arm 3 '.
  • the stirrer arm stub 6 is rigidly attached to the stirrer hub by means of a permanent weld seam.
  • centering halves 7, e.g. Centering bushes inserted and locked via position welding points 8.
  • the rest of the stirring arm 3 ' receives the counterpart centering agent halves 7', e.g. Centering bushes with position welding points 8.
  • Stirrer arm stub 6 and stirrer arm rest 3 ' are positioned relative to one another via centering pins 9 in centering bushes 7 and 7', respectively.
  • stirrer hub 2 For the installation of the stirrer 1 in the stirrer, the stirrer hub 2 with the rigidly connected two stirrer arms is inserted through the assembly opening into the stirrer and attached to the stirrer shaft without gaps.
  • the dome-like cap 10 is welded to the stirrer hub 2 without a gap and polished smooth.
  • the stirrer arm rest 3 ' is placed on the stirrer arm stub 6 after introduction into the stirring vessel and the gap between the two parts is welded in a positive and non-positive manner. This is followed by grinding and polishing the weld seam so that a completely smooth surface is obtained.
  • the weld seam is cut exactly to the line.
  • the agitator hub 2 is optionally designed in a known manner for the non-positive connection to the agitator shaft.
  • the lower part of the agitator hub can also be designed so that it protects the mechanical seal underneath as a rinsing attachment.
