Problems solved by technology

[0005] In order to overcome the shortcomings of the existing uneven distribution of cooling gas flow on the grate surface, increase the complexity of the equipment, and occupy the internal space of the equipment, the present invention provides an adaptive cooling high-temperature bulk furnace grate element, the invention itself It is a resistance grating with a certain minimum flow resistance, and also has the function of a flow regulator

Embodiment 1

[0014] figure 1 It shows a cross-sectional view of a grate cooler. There are many grate plates on the surface of the grate bed, and there is a large clinker conveying cavity on it. The air chamber under the grate bed is also relatively large, and the clinker conveying cavity Gas pressure P and gas pressure P in the air chamber 0 Controlled by the fan, these two pressure values ​​can be regarded as constant during the working period. When the particle size of cement clinker on a certain grate plate is large or the thickness of the material layer is thin, the resistance of the material layer to the gas will become smaller. At this time, if the gas penetrates the material layer from bottom to top without additional restrictions, The flow rate of this grate plate will increase, and in serious cases, a gas short circuit will occur. At this time, since the pressure P on the upper part of the material layer remains basically unchanged, the flow resistance of the material layer beco...

Abstract

The invention relates to a self-adjust fire grate component for cooling high temperature bulk material, its fluid resistance can be change automatically in accordance with the width of material layer, reaching the goal of atomically control flux of cooling air, with the structure of a lay of labyrinth and a layer of flexible film. The pathbent plate of labyrinth is formed by upper 6 (3), the space between them is fixed for preventing bulk material falling down from the surface of fire grate component; changeable fluid resistance space structure is made of flexible film (4) and shell (1) and the change of space between them is realized by the 7 of flexible film (4), the space changes with the level of 7 of flexible film (4) changes, so that the resistance to air fluid resistance has been changed, and the air flux is adjusted, the level of 7 of flexible film (4) is decided by that of pressure of the material layer.

Description

technical field [0001] The invention relates to a grate element used for cooling the surface of a high-temperature bulk material cooling bed, in particular to a variable resistance grating plate used on the grate bed of a cement clinker grating cooler. Background technique [0002] The surface of the grate bed of the cement grate cooler is covered with many grate elements. The surface of the grate bed has two functions, one is to undertake and transport cement clinker, and the other is to let the cooling gas pass through each grate element to the cement on it. The high-temperature clinker is blown to cool it down. The current practice is to set up one or several common air chambers under the castor bed, and use a fan to blow cooling gas into the large air chamber. The cement clinker takes away the heat to achieve the purpose of cooling the high temperature clinker. But in most cases, the particle size of cement clinker is uneven, the distribution on the surface of the cast...
