Definitions

  • the invention relates to a cooling grate for a bulk goods cooler, in particular for fired goods such as cement clinker, the
  • Top forms a supporting surface supporting the refrigerated goods, the cooling grate being composed of a plurality of fixed, partially overlapping shaped profiles, between which gas passage channels are formed.
  • Cooling grates of this type are used for receiving and for cooling fired material supplied by the cooler.
  • the cooling grate has to fulfill essentially three functions, namely to carry the firing material to be cooled, to provide feeds for the cooling gas and to form a basis for a conveyor system for the firing material to be cooled.
  • the conveyor system ensures that the fired goods are transported over the fixed cooling grate.
  • Such a cooler is known from EP-B-0 676 031. There is one composed of several shaped profiles
  • Cooling grate described.
  • Two different types of shaped profiles are used.
  • the first type is designed as a bar which is essentially rectangular in cross section, the underside of which has a central depression which extends in the longitudinal direction.
  • the second type of shaped profile has the shape of an inverted T in cross-section, the transverse parts of the T being provided at their free ends with an edge which extends in the direction of the longitudinal part of the T.
  • the two types of shaped profiles are arranged alternately.
  • the edges on the transverse parts of the two immediately adjacent T-like shaped profiles engage in the recess of one of the rectangular shaped profiles. This creates a gas passage channel between a rectangular shaped profile and a T-shaped shaped profile.
  • the channel is not straight, but has several deflections to prevent material diarrhea.
  • a disadvantage of the known cooling grate is that the shaped profiles with their recesses or their edges are expensive to manufacture and are also quite difficult to assemble.
  • two different types of shaped profiles are required,
  • a cooling grate of a different type is described in DE-A-195 37 904. It is formed from several shaped profiles, which are joined together closely with their long sides. The shaped profiles have groove-like recesses on their longitudinal sides intended for contact with adjacent shaped profiles, which run obliquely from the bottom to the top. In the assembled state, these groove-like recesses form gas passage channels from the underside of the cooling grate to the top thereof.
  • the disadvantage of this is that the shaped profiles with their recesses are expensive to manufacture. This applies all the more because a separate recess is required for each individual gas passage channel.
  • cooling grate It is also known to assemble the cooling grate from a plurality of profiles which are U-shaped or U- and T-shaped and are arranged alternately. Such cooling gratings are complex to manufacture and assemble.
  • a movable sliding grate is used instead of the fixed cooling grate.
  • the sliding grate consists of several rows, which are alternately fixed and movable. The movable rows are moved back and forth by means of a drive device.
  • the shaped profiles are expediently arranged transversely with respect to the conveying direction of the items to be cooled. On the one hand, this results in a favorable arrangement of the gas passage channels, on the other hand, and above all, a greater braking effect is exerted on the firing material.
  • a carrier which has position-determining receptacles for the shaped profiles.
  • the recordings enable simple and precise positioning of the shaped profiles on the supports. This is especially true when the position and the angular position are determined by the recordings.
  • Figure 1 is a sectional view of a cooling grate according to a first embodiment of the invention.
  • FIG. 2 shows a sectional view of a cooling grate according to a second exemplary embodiment of the invention
  • FIG. 3 shows a sectional view of a cooling grate according to a third exemplary embodiment of the invention.
  • Fig. 4 is a sectional view of a cooling grate according to a fourth embodiment of the invention.
  • ⁇ 54 0 G TJ Cn 54 G cd r-4 G ⁇ N ⁇ 0 ⁇ 4-1 G 3 rH cq -H TJ -P ⁇ r
  • the front outer part 43 protrudes freely from the serration 36.
  • the shape and the distance of the serration 36 from one recess to the next is selected such that the shaped profile 4 with its front outer part 43 engages over the outer part 42 'of the forwardly adjacent shaped profile 4' seen in the conveying direction.
  • the gas passage channel 5 runs between the mutually parallel outer surfaces 42 ', 43 straight.
  • the position of the shaped profiles 4, 4 'relative to one another is determined by the gap 36 of the main support 3.
  • the gas passage channels 5 are defined in terms of their design by the design of the serration 36 and the shaped profiles 4.
  • the width of the gas passage 5 is determined on the one hand by the distance between the serrations 36 and on the other hand by the shape and thickness of the material of the outer parts 42 ', 43. Adjustments are not necessary. It is therefore sufficient to assemble the cooling grate 1 that after the support structure 2, 3 has been built up, the shaped profiles 4 are inserted one after the other into the serration 36 of the side member 3 and fastened there.
  • the cooling grate 1 thus enables a high degree of prefabrication, so that only the individual parts then need to be assembled on the construction site. The result is a cooling grate that has advantages in terms of simple construction on the one hand and the quality of the cooling gas flow on the other.
