Definitions

  • the invention relates to a device for mixing and / or crushing, consisting of a cylindrical container for receiving the material to be treated and at least one drivable circulating element, which is mounted concentrically with respect to the container axis and extends essentially to the inner wall region of the container, and at least one with respect to the container axis Eccentrically and rotatably mounted, revolving with the circulating element and acting on the circulated material, which can be driven with the same or a different speed and / or direction of rotation from the circulating element, in the area of at least one wall-side section of the circulating element, at least one rotating with it Nozzle arrangement is provided which extends essentially over the axial length of the circulating element and can be acted upon with suction and / or pumpable media.
  • a drum is rotatably mounted in a fixed housing, and drums are arranged around the circumference of which drivable rollers are arranged to drive this inner drum.
  • the unit consisting of the inner drum and the rollers forms the circulating element, whereby by means of the rollers, the mixture is ground and kneaded simultaneously.
  • Roof-like water supply channels are arranged between and parallel to the rollers. Since in this known device the rollers are at the same time part of the circulating element and tool, it is not readily possible to meet the requirements resulting from the different composition and different condition of the material to be treated in the same way in terms of optimally treating the material .
  • the spraying takes place in an area in which the material to be treated is exposed to relatively low circulation or movement forces due to the existing distance of the tools or relevant parts of the circulating element from the injection point. At least with certain critical materials, tough phases, caking and lump formation may be expected.
  • the invention has for its object to design a device of the type mentioned in the simplest possible manner so that, in particular when avoiding the need to carry out spraying operations, regardless of the composition and the respective condition of the material to be treated with a short throughput or processing time optimal formation of the material and an extremely even process product is always obtained from lump formation, baking and toughening phases.
  • the object is achieved according to the invention in that the nozzle arrangement in the area of a wall-side agitator Circulating element is provided, and that the stirring blade is adjacent and the tool is arranged in the working area of the nozzle arrangement.
  • the nozzle arrangement Due to the arrangement of the tool in the working area of the nozzles, which is provided separately and can be influenced independently of the circulating element or agitator, there is an interaction of the circulating element, regardless of the drivable tool and for spraying the material to be treated, the nozzle arrangement, regardless of the composition and the best possible working conditions can always be observed, depending on the condition of the goods to be treated.
  • the arrangement and design of the injection arrangement results in a surprisingly uniform distribution of the sprayed, preferably gaseous medium in the product, with the processes of stirring, comminution and injection, which can be influenced separately, mutually supporting one another in a particularly advantageous manner in such a way that an unexpectedly favorable result is achieved.
  • the nozzle arrangement advantageously consists of a tube which runs parallel to the wall-side element of the circulating element and is provided with wall openings or spray nozzles.
  • the nozzle tube can be combined with the wall-side impeller of the circulating element to form a unit.
  • the tool located in the working area of the nozzle arrangement is designed as a chopper. This results in an additional mixing effect and at the same time an improvement in the chopper effect. Despite the operating conditions, which are difficult due to the injection, it is possible with this configuration to minimize the throughput times with high quality of the Ensure process product.
  • the nozzle tube is preferably attached such that it can be rotated so that the spraying angle of the respective medium, which can consist of liquid or steam, can be adapted to the particular circumstances in order to optimize the process.
  • a circulating element 5 is arranged in a cylindrical container 1, which is connected in a rotationally fixed manner to a support shaft 3 which is rotatably mounted in the container concentrically to the container axis 20 by means of bearings 2.
  • the circulating element 5 is designed as a frame-shaped arrangement which extends essentially to the inner wall region of the container 1.
  • the frame-shaped circulating element 5 comprises at least one part 21 which extends parallel to the container axis 20, preferably in the form of an impeller, and two lateral support parts 22 which extend in the radial direction.
  • a second drive 12 for the chopper 6 which is independent of this first drive is provided.
  • the output shaft 11 of the second drive 12 is rotatably mounted in the support shaft 3 for the circulating element 5 by means of bearings 14 and via a gear 8 shown schematically and as an example, 9, 10 connected to the chopper 6.
  • the transmission is housed in a cavity 13 of the right side support part 22 of the circulating element 5.
  • the cavity 13 is sealed in such a way that on the one hand penetration of the material to be treated into the cavity 13 and on the other hand lubricants are prevented from escaping from the cavity.
  • a pipe 19 connected to the impeller 21 or integrated into the impeller is shown schematically in the drawing, in the wall of which a plurality of nozzle openings or wall openings 17 are formed.
  • This nozzle tube 19 is fed with a liquid or vapor medium via a feed 16 running in the circulating element 5, such as bores and / or lines.
  • the nozzle tube 19 can be attached in the region of the top or rear side of the impeller 21 and is preferably freely rotatable, so that the radiation angle of the liquid to be sprayed or the steam to be introduced can be varied in accordance with the particular circumstances.
  • the nozzle tube 19, which extends over the entire axial length of the impeller 21, is positioned such that the medium emerging through the wall openings 17 reaches the area of influence of the chopper 6 adjacent to the blade, which results in an additional mixing effect on the one hand and As a result, more uniform granules can be obtained.
  • the device according to the invention also results in a more economical method if one solvent is to be replaced by another.
