Food cooler for cement clinker and the like.

The present invention relates to a grate cooler for cement clinker and the like, e.g. ore sinter, calcined phosphate, etc.

It is known to design a grate cooler for cement clinker and the like with several grate sections which have different feed speeds to produce different bed thicknesses in such a way that. the first grate section is given a lower feed rate than the following, whereby the former can be inclined and the latter can be arranged horizontally.

The purpose pursued here is in the inclined and the grate part, which is driven more slowly, collect a thick layer of refrigerated goods in order to achieve better heat transfer and a to achieve higher recuperation while on the downstream horizontal food part is driven with a feed speed that a normal layer thickness of the refrigerated goods of approx. 200-250 mm.

In practical operation, it is now the case with certain refrigerated goods grains shown that the thick layer on the inclined ^ grate part sloughs off prematurely to the horizontal grate part before the actual desired thickness of the goods to be cooled has been reached. It is true that there is one of the downstream horizontal grate part Backward damming effect on the formation of a thicker layer in the inclined grate part, but with well-flowing refrigerated goods this effect is not sufficient.

It is therefore proposed according to the invention to allow the second grate part to rise. This will make the Backflow to the first grate part is improved so that the desired layer thickness on the entire first grate part ™ is achieved.

Furthermore, it is achieved by the arrangement according to the invention that the drop point of the goods to be cooled from the second section is higher and thus additional lifting work for the further transport of the refrigerated goods can be saved if necessary.

According to a further feature of the present invention, the second grate section can be designed as a towing grate,

however, all other known grate constructions that require the goods to move can also be used «

The invention is illustrated schematically, for example, in the accompanying drawing the downward sloping grate part with the one above thicker chilled goods layer and with 2 the rising again Part of the grate labeled with the normal layer of goods to be cooled. At 3 there is the continuous supply of the goods to be cooled and at 4 the refrigerated goods leave the cooling grate

The grate parts 1 and 2 are designed perforated and with cooling air from chambers, not shown, which are under the grate, flows through

The present application relates in particular to a further development of the one shown in DAS 1 170 307 Grate cooler.
