Definitions

  • the invention relates to a moving grate cooler according to the preamble of claim 1.
  • the grate plate supports are designed as welded or cast structures. Since these are relatively large machine parts that also have to be subjected to extensive subsequent processing, the manufacture of the known grate plate carriers is quite complicated.
  • the invention is therefore based on the object of designing a moving grate cooler in accordance with the preamble of claim 1 in such a way that particularly simple manufacture results which, in particular, does not require any complicated mechanical reworking.
  • the grate plate carrier thus consists of a solid round steel extending over the entire length of the row and of webs placed on this round steel for holding the grate plates.
  • the solid round steel is only cut to length and does not undergo any further machining.
  • the attached webs which are expediently formed by web plates welded upright onto the round steel, do not lead to the warping of the beam.
  • the grate plate carrier according to the invention is somewhat heavier than the previous designs, there are significant price advantages. There are no high demands on production, which is particularly advantageous when manufacturing in developing countries.
  • the grate plate carrier according to the invention allows better air flow under the grate plates than the previously known designs, in particular welded box girders.
  • a moving grate cooler usually contains fixed and movable grate plates which follow one another in the conveying direction of the cooler and are arranged next to one another in rows running transversely to the conveying direction.
  • Grate plate carriers serve to hold at least one grate plate in each row. There are fixed grate plate carriers and movable grate plate carriers.
  • a movable grate plate carrier is illustrated.
  • It contains a solid round steel 1 extending over the entire length of the row, which can have a diameter of 140 mm, for example.
  • the individual grate plates 2 are each supported on two web plates 3 arranged at a distance from one another.
  • the center line of the individual grate plates 2 is designated by 4 in FIG.
  • All web plates 3 in a row are connected via a longitudinal strut 5 which is arranged parallel to the round steel 1 and is preferably welded to the web plates.
  • Fastening bolts 6, which are arranged between adjacent web plates 3 and which on the one hand engage in an eye 2a arranged on the underside of the grate plates 2 and on the other hand reach through a bore 5a of the longitudinal strut 5, are used to hold the grate plates 2, nuts 7 arranged on the fastening bolts 6 Support on the longitudinal strut 5.
  • the round steel 1 is connected to two feet 8, by means of which it is supported on two supports 9.
  • These supports 9 - if the round steel 1 is the movable grate plate support - can for example be part of a oscillating frame that can move back and forth perpendicular to the plane of the drawing in FIG. 1 and which provides the necessary movement in the movable grate plate support and thus the movable grate plates carried by it Conveying direction of the moving grate cooler gives.
