Definitions

  • the invention relates to a static mixer for mixing two material components when emerging from two leading into a common mixing tube outlet channels of a two-component cartridge.
  • Static mixers are known and consist of a number of mostly same, axially juxtaposed and each usually 90 ° angularly offset mixing blade elements which are rigidly connected to each other and sit in a mixing tube, the inlet side has a connectable to the outlets of the two-component cartridge sleeve.
  • the mixing action of such static mixers is to subject the total material flow emerging from the two outlets of the chambers of the two-component cartridge as efficiently as possible to repetitive strand pitches, directional strand movements and strand mergers, thereby achieving the intimate and homogeneous mixing of the two components.
  • the object of the invention is to provide such a static mixer, which achieves the above-mentioned objectives as well as possible for mixing coaxial material emerging from a two-component material strands in a very simple construction.
  • the static mixer according to the invention thus consists first of all in a known manner of a number of axially juxtaposed and firmly interconnected, each mutually angularly offset mixing elements, each of which may have the shape of double helix sections.
  • a baffle plate arranged upstream of the mixing element row is provided on the input side, which has a central pin which extends upstream into the flow of material and which merges divergently into an axis-perpendicular plate in the flow direction.
  • the plate has an approximately star-like configuration, the star arms depending on the consistency of the materials to be mixed different surface and large, and between their star arms also the consistency in shape and size adapted passages through which the material in a corresponding Number of strands of material passes and thus enters the region of the first mixing element.
  • the size of the passages between the star arms also depends again on the consistency of the materials to be mixed.
  • the pin extends into the material flow of the inner material component coaxially from the two-component cartridge leaking material components, and the preferably arcuate diverging design of the transition from the pin into the star-like plate serves to effectively and evenly distributed over the cross-section of the inner material flow deflect radially outward to bring it together over the entire mixer cross-section with the radially outside entering outer material component so that the two material strands exiting coaxially from the two-component cartridge already enters the first mixing element of the mixing element row already in a merged form.
  • such star-shaped plates of the same or similar configuration between a plurality of successive groups of juxtaposed mixing elements can also be provided in each case for individual groups of successive mixing elements.
  • FIG. 1 to 8 each in side view, perspective view and bottom view of some embodiments of static mixers according to the invention.
  • a baffle plate 1 with upstream facing centric pin 11, a divergent transition into the actual plate, and star-like configuration provided in the embodiments of the Fig. 6 till 8 Several such baffles 1 are provided, namely in each case on the input side and in each case according to a group of mixing elements. 2
  • the input-side plate is denoted by 1, and the mixing elements are denoted by 2.
  • the further plates between successive groups of mixing elements 2 are in the Fig. 6 to 8 labeled 1a and 1b.
  • the mixing elements 2 are formed in all the illustrated embodiments in a conventional manner, namely as arranged at 90 ° angularly offset mixing elements, each having the shape of a two-start coil section which undergoes a 180 ° rotation.
  • the input-side baffle plate 1 (and also the optionally subsequent baffle plates 1a, 1b) each have an upstream facing central pin 11, an arcuate diverging transition region 12 which may be conical or pyramid-like, and the actual plate 13, respectively in the illustrated examples has four star arms, which protrude radially outward and depending on the embodiment form more or less wide passage openings 14 between them, which are more or less far in the radially outer region.
  • the size of the passage openings 14 and their configuration, and accordingly the area size and configuration of the star arms of the plate 13, each depend significantly on the consistency of the materials to be mixed. It is understood that the smaller the passage openings, the greater the pressure loss and thus the necessary extrusion pressure. The tougher the material components to be mixed, the larger the passage openings accordingly.
  • the mixing elements 2 are each offset by 90 ° from each other, and each mixing element undergoes a 180 ° rotation.
  • this is only an example, it can also find other designs of mixing elements and other rotational offset angle application.
  • the plates 1 each have a four-arm star configuration. But there may also be fewer or more star arms.
  • each baffle plate 1 is oriented so that two of the four star arms lie in front of the entry edge of the subsequent mixing element.
