Definitions

  • the invention relates to a moving grate cooler according to the preamble of claim 1.
  • the invention is therefore based on the object of designing a sliding grate cooler in accordance with the preamble of claim 1 in such a way that the longitudinal slots between adjacent grate plates are reduced or completely avoided.
  • only individual grate plates are firmly connected to the associated grate plate support in the individual grate plate rows, while the grate plates following the fixed grate plate on both sides of the same row are only firmly connected to the fixed grate plate, against the grate plate carrier, however, are relatively movable under the influence of temperature.
  • the longitudinal slots between the grate plates are reduced accordingly. If only a single grate plate is used, the longitudinal slots can even be completely avoided.
  • 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.
  • 1 to 3 illustrate the connection of the individual grate plates in a row to the grate plate support and the connection of the individual grate plates to one another.
  • the grate plate carrier contains a support body 1 extending over the entire length of the row. Bars for holding the grate plates 2 are placed on this support body 1. These webs are formed by web plates 3, which are placed upright on the support body 1. The web plates 3 are preferably welded to the support body 1.
  • the individual grate plates 2 each have two molded projections 2a on their underside.
  • the individual grate plates 2 are supported with these approaches 2a each on two spaced-apart web plates 3.
  • the center line of the individual grate plates 2 is designated in FIG. 4 by the reference number 4.
  • All of the web plates 3 in a row are connected via a longitudinal strut 5 which is arranged parallel to the support body 1 and is preferably welded to the web plates.
  • the fastening screws 7 are fastened by screwing with nuts to the longitudinal strut 5.
  • Such fastening of the grate plates 2 enables the grate plates 2 to be displaced within the scope of expansion differences in the event of temperature fluctuations relative to the grate plate carrier.
  • the fastening bolt 6 remains unchanged in its position in relation to the grate plate carrier, so that the grate plates 2 move on the fastening bolt 6 via the cast-on eyes 2b.
  • This screw connection 9 is shown in particular in FIG.
  • the support body 1 is connected to two feet 11, by means of which it is supported on two supports 12 (however, only one foot 11 with support 12 is shown in the detail of FIG. 1). If the support body 1 is the movable grate plate support, these supports 12 can, for example, be part of a oscillating frame which can be moved 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.
  • the grate plates 2 shift relative to the grate plate support and only the middle, fixed grate plate 2 remains unchanged in its position with respect to the grate plate support.
  • the eyes 2b shift in the same way on the fastening bolts 6. So that the fastening bolts 6 are not carried along with the eyes 2b due to frictional forces, the fastening bolts 6 are laterally limited by the web plates 3, cf. 1 and 2. In this way, an oblique pull on the retaining screws 7 fastened to the fastening bolt 6 is also avoided.
  • the distance between the eyes 2b and the retaining screws 7 is dimensioned so large that sufficient expansion differences of the grate plates 2 are possible.
