Definitions

  • the invention relates to a tube cooler with a lifting element for at least partially accumulating material, e.g. Clinker.
  • Such lifting elements are fixed to the jacket of the tube cooler directly or with the interposition of brackets.
  • tube coolers of this type the material to be cooled is taken to a greater or lesser extent when the tube cooler is rotated by lifting elements fixed to the tube jacket, in order to then fall away from these lifting elements and thereby come into intimate contact with cooling air.
  • the material is transported in the tube cooler due to an inclination towards the exit.
  • the tube cooler can be designed as drums and can be combined as a so-called planetary or satellite cooler to form a cooling unit.
  • coolers are e.g. needed for cooling clinker in cement production.
  • a rotary kiln which is provided in a preheating zone with projections or the like, which can also have the shape of frames, which have such edges in the direction of rotation that the material to be heated is penetrated or cut through. In this way, a favorable heat transfer can be achieved with fine-grained material without the formation of dust.
  • the material to be cooled is usually in the first area of a tube cooler both fine-grained and in more or less large chunks.
  • lifting beams or lifting bars are used, which are attached to the jacket of the tube cooler and have a closed driver surface that points essentially towards the center of the tube cooler.
  • the invention is based on the object of providing a tube cooler with a lifting element of the type mentioned at the beginning, with which material accumulating in lumps can be taken along and broken in the first region of a tube cooler.
  • a tubular cooler with a lifting element in which the lifting element has a fastening section which can be fixed to the jacket of the tubular cooler and a driver section which extends essentially at right angles thereto and which has at least one passage opening which passes through this section and which is of a substantially U-shaped shape , is enclosed with its two legs from the fastening section, the shock resistance and the resistance to falling chunks increasing crusher bars.
  • the passage opening or the passage openings provided in the driver section cause fine-grained material to fall through the passage opening / passage openings of the driver section, so that the driver surface is not occupied, so that this driver surface can also take chunks of the material to be cooled with rotation of the tube cooler. This breaks the chunks in the area of the tube cooler intended for this purpose and thus reduces the wear stress in the downstream zones of the cooler. It may be expedient to use, in addition to the lifting elements according to the invention, those of the previously known type in a ring. Furthermore, it is possible to provide a ring alone with the lifting elements according to the invention and to equip one or more of the adjacent rings with lifting elements of the known type.
  • the tube cooler according to the invention can also be designed such that in the lifting element the passage opening enclosed by the breaker bar is divided by at least one rib. Such ribs can promote the impact resistance of the driver section and also increase the driver effect.
  • a jacket 1 of a tube cooler which has an outer shell 2 made of steel, which is lined on its inside with refractory material 3.
  • Lifting elements 5 are connected to the casing 1 and are tightened by anchor screws 6 against a holder 7 which is supported on the inside of the shell.
  • the partial section of Fig. 1 relates to a crushing zone located near the inlet of a tube cooler.
  • Each lifting element has a fastening section 8 and an almost normal driving section 9. These two sections 8, 9 give the lifting element an essentially L-shaped shape.
  • the fastening section 8 is here provided with two lugs 10 which engage in the holder 7 in the assembled state.
  • the approaches 10 are provided with openings 11 for the anchor bolts 6.
  • the driver section 9 is delimited in the embodiment according to FIGS. 1 to 4 by a crushing bar 12 which has a central section 13 and two adjoining legs 14 which diverging in the direction of the fastening section 8.
  • the crushing bar 12 thus, together with the fastening section 8, delimits a passage opening 15.
  • a rib 16 which extends from the fastening section 8 and extends to the central section 13 of the crushing bracket 12, divides the passage opening 15 into two equal parts. Furthermore, supporting ribs 17 are provided, which also extend from the fastening section 8 and support the legs 14 of the crushing bracket 12.
  • the surfaces of the middle section 13 and the leg 14 lie essentially in one plane, while the surface of the rib 16 is offset inwards.
  • the lifting element is a one-piece casting made of heat-resistant cast steel.
  • the crushing bracket 12 consequently remains essentially free and is therefore suitable for taking with it chunk-like material to be cooled which then falls from an elevated position from the driver section 9 and strikes the central section 13 of a lifting element which is then in the falling line and is thereby broken and crushed can.
