Abstract (en)
[origin: EP1881287A1] The device for cooling bulk material e.g. cement clinker from upstream process stage of oven, comprises a grate (3) with a mechanism for supplying cooling gas, a tub for arranging a supporting structure and a dispersion element on its edge, and a material sump intended to a conveying direction (60) on the side of the dispersion element. The grate conveys a layer of the bulk material along the conveying direction, has conveying elements and forms an even support surface for the layer of the bulk material. The support surface is partly provided with a laminar exhaust mechanism. The device for cooling bulk material e.g. cement clinker from upstream process stage of oven, comprises a grate (3) with a mechanism for supplying cooling gas, a tub for arranging a supporting structure and a dispersion element on its edge, and a material sump intended to a conveying direction (60) on the side of the dispersion element. The grate conveys a layer of the bulk material along the conveying direction, has conveying elements and forms an even support surface for the layer of the bulk material. The support surface is partly provided with a laminar exhaust mechanism that comprises a spatially enlarged dispersion element, on which the bulk material directly rests, and the supporting structure arranged under it. The tub has a supply connection at the bottom for the cooling gas. The dispersion element and the supporting structure are combined into modules, which are arranged exchangeably at the grate and which are intended in matrix arrangement. Footpaths projecting on the grate and or its boards are arranged in the bulk material transverse to the conveying direction. The supporting structure connects the together-bordering modules directly to each other, and is formed as a supporting grid, which is arranged on plate elements arranged in cross connection. The dispersion element and the supporting structure are arranged in a movable element of the grate. The dispersion element is formed from the support surface of the grate in projecting manner. Frames that are oriented in the conveying direction, are intended on the boards, which form troughs holding together with the footpaths. The frames are arranged at sidewalls of the boards. An additional frame is arranged at inner side of a sealing section of the boards.
