Description

The invention relates to an apparatus for cooling clinker and other materials and can be used in the building materials industry for cooling cement clinker. Known grate refrigerators, which enters the material after firing in the furnace. The material is distributed and transported along a grate through which air is blown. This provides cooling of the material and heating of the air entering the C13 combustion furnace. A disadvantage of the known refrigerators lies in the supply of cooling air without considering the height of the clinker over the grid area, which reduces the cooling efficiency of the clinker and the heating of air. The closest to the invention according to the technical nature is a grate cooler for cooling bulk material, containing a loading shaft, a grate, an air distributor located under the grate grate With ducts having vertical side walls and sloping surfaces forming a V-shaped bottom, cooling air ducts and conveyor to remove spillage 23. In said refrigerator, although the distribution of cooling air over the length of the grill is carried out, the air in within the area bounded by the Korby air diffuser, also comes under. the lattice without taking into account the distribution of the clinker layer over the lattice width, which negatively affects the qualities. cooling the material. The purpose of the invention is to increase the cooling efficiency. This goal is achieved by having a grate cooler for cooling bulk material containing a loading shaft, an grate grid, an air spreader with a duct with vertical side walls and sloping surfaces forming a V-shaped bottom located under the grate grid. , cooling air supply ducts and conveyor for removal of spillage, bars are placed under the grill with the possibility of a cold crosswise to the longitudinal axis lnik reciprocating movement, the box secured to beams Inclined bottom surface us connected between themselves and with the side walls by hinges, wherein the side wall ducts, partitioned conductive diffuser width are movable along the beams. FIG. 1 schematically shows a grate cooler, longitudinal section; in fig. 2 is a section A-A in FIG. 1. The furnace 1 enters the refrigerator 2, which contains a loading shaft 3, a grate 4, an air distributor 5 with ducts 6 and ducts 7 and 8 of the cooling air supply, conveyors 9 for spillage removal and estrus 10 and 11 for guiding the clinker and located under the grate bars to place 12 of his collection. The air distributor 5 is partitioned along the length by partitions 13 (one is shown). In each of the sections under the grate 4, the beams 15 are placed on the support bearings. Beams 15 have drives 16 that are connected to the side walls 18 of the box 6 with the help of hollow bars 17. The V-shaped bottom of the box 6 is formed by inclined surfaces 19, pivotally interconnected and side walls 18 of the box 6. In the lower part of the bottom there are slots 20 for the passage of the prow. Flue 7 serves to supply air to the box 6, and flue 8 to supply air to the rest of the sublattice space. The beams 15 may move in both directions along their axis. The distance between the walls 18 is taken. equal to the width of the strip of material of maximum thickness located on the grate 4. The dimensions of the bottom are determined from the condition that the spill is poured out through the slots 20. The dimensions of the slots 20 are chosen not smaller than the dimensions of the slots in the lattice 4. The cross section of the beams 15 is determined from the strength conditions bend on the weight of the box. The refrigerator works as follows. The material from the furnace 1 through the loading shaft 3 is fed to the grid 4 and is distributed over it by thicker layers in its middle part, and on the sides by a layer of lesser height. The air supplied through the duct 7, through the duct 8, is blown in necessary quantities through a thick layer of material in the middle part of the grill 4 and cools it, while the air is heated efficiently. From the sides of the grill 4, where the layer of material is smaller, the air through the duct 8 is supplied in a smaller amount. The spillage of material through the grate 4 falls partially into the box 6 and through the slots 20 along with the rest of the spillage is removed by the conveyor 9. In case of a strip of a thick material layer to the right

or to the left from the middle of the lattice, the duct 6 on the beams 15 is shifted in the corresponding direction. If the width of the strip of a thick layer of material is reduced, then the actuators 16 through ti gi. 17 bring the walls 18 closer together, the inclined surfaces 19 swivel and the box B becomes narrower. In this way, the distribution of the air distributor in width is not carried out.

The use of the proposed refrigerator improves its efficiency, as it improves cooling of the material in the middle part of the lattice with a thick layer of material. This leads to a more efficient use of air, and consequently, to save fuel.
