Definitions

  • the invention relates to a lifting element for tube coolers for at least partially accumulating material, e.g. B. clinker, which has a fixable on the jacket of the tube cooler mounting section and a substantially perpendicular to the driver section.
  • a lifting element for tube coolers for at least partially accumulating material e.g. B. clinker
  • Such lifting elements are fixed to the jacket of a tube cooler directly or with brackets interposed.
  • 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 transport of the material in the cooler R ear occurs due to an inclination in the direction of 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.
  • 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 object of the invention is to create a lifting element of the type mentioned at the outset with which material accumulating in chunks can be taken along and broken in the first region of a tube cooler.
  • 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 invention further provides that the driver section is fork-shaped and each passage opening lies between two tines extending from the fastening section.
  • the invention further provides that at least two tines are provided.
  • the lifting element according to the invention can also be designed such that the passage opening of the driver section is enclosed by an essentially U-shaped breaking bracket with its two legs extending from the fastening section.
  • the use of such a shackle can increase the impact resistance of the lifting element and thus its resistance to falling chunks.
  • the lifting element according to the invention can also be designed in such a way that the passage opening enclosed by the breakbar 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 by a break bar 12 which has a central section 13 and two adjoining it, in Direction on the fastening portion 8 has diverging legs 14.
  • the crushing bar 12 thus, together with the fastening section 8, delimits a passage opening 15.
  • a rib 16 which starts 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, support ribs 17 are provided, which also extend from the fastening section 8 and support the legs 14 of the crusher bar 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.
  • FIG. 6 and 7 relate to a further embodiment of the lifting element according to the invention, which differs from the previously described embodiment solely in the design of the driver section 20.
  • This driver section 20 is here from a total of three from the fastening section 8 outgoing tines 21-23 are formed, of which the outer tines 21, 23 converge slightly starting from the fastening section 8. Between the prongs 21-23, passage openings 24, 25 remain free, through which fine-grained material can fall through, in order also to allow a sufficiently safe taking away of lumpy material in this embodiment.
