Stationary grate plate rows alternate with reciprocating grate plate rows as seen in the conveying direction, which are fastened via their corresponding reciprocating grate plate carriers to one or more longitudinally movably mounted driven push frames.
  • the bulk material delivery rate is decisively influenced by the difference between the cement clinker volume moved in each advance stroke in the conveying direction and the clinker volume which is undesirably moved counter to the conveying direction during the return stroke.
  • the crossbar-shaped pushers are mounted on top of vertical drive plates aligned in the longitudinal direction of the radiator, which extend through respective longitudinal slots of the chilled grate and are driven from beneath the chilled grate. It verproves that it is expensive, the loaded with refrigerated goods cooling grate at the passage points of the drive plates against rust diarrhea seal and thereby keep the material wear occurring within limits.
  • a cooling tunnel for cooling and / or freezing refrigerated goods by means of cold air with application of the so-called "walking floor” conveying principle is known in which the plurality of adjacently arranged floor elements of the cooling tunnel in the transport direction together forward, but not together, but moved back from each other separately.
  • a high bulk material bed should form, which fills the entire cooling tunnel cross-section, so that the cooling gas flows through the stepwise moving bulk material in countercurrent.
  • the floor elements themselves remain uncooled by the cooling gas, so that even therefore the known cooling tunnel would not be suitable to cool from the discharge end of a rotary kiln falling red hot cement clinker.
  • the direct contact of the fresh hot cement clinker with the surface of the floor elements would lead to a high thermal-mechanical wear load and therefore to an insufficient service life of such a cooling tunnel in the case of hot cement clinker.
  • the invention has for its object to provide a bulk material cooler, especially for hot cement clinker, the delivery capacity, the service life and the efficiency of the radiator increases and the wear problems are reduced.
  • the cooling grate carrying the hot goods to be cooled is composed of a plurality of units extending in the longitudinal direction of the refrigerator.
  • ckenden juxtaposed elongated floor elements composed, which are at least partially independently controlled between a Vorhubposition inchentransportides and a Ruhubposition movable, so that the refrigerated goods is gradually fed to the Walking Floor conveying principle through the radiator.
  • the cooling grate composed in this manner is permeable to the cooling air which flows through the cooling grate and the bulk material bed mounted thereon in crossflow from bottom to top, ie the bottom elements simultaneously serve as bulk material transport and cooling grate ventilation elements.
  • the floor elements are moved forward together during their forward stroke movement, but are not moved together in their return stroke movement, but are moved back in succession in at least two groups in at least two temporally successive steps, in which only a part of the floor elements, z. B. only every second bottom element seen is moved back across the radiator width.
  • the floor elements are controlled under the dormant bed of bulk material withdrawn so that the bed of bulk material remains at rest and does not join the
  • the controlled movable individual floor elements of the bulk material cooler according to the invention are designed in the manner of an elongated hollow body profile and they have seen in cross-section carrying the refrigerated goods and for the cooling gas from bottom to top permeable top and a spaced therefrom thedegut-Rost slidefall preventing underside.
  • the underside of all floor elements a plurality of distributed over the length of cooling gas inlet openings for ventilation of the floor elements and with the cooling grate on.
  • the drive of the floor elements to their movement between their Vorhubposition and their remindhubposition takes place from below the cooling grate.
  • the floor element upper sides bearing the refrigerated goods can be provided with any perforations.
  • the tops of the individually individually and / or longitudinally movable in groups floor elements each consist of spaced apart mirror image opposite, but offset from each other arranged gable V-profiles whose V-legs interlock with space inside each other, which latter a labyrinth forms for the refrigerated goods as well as for the cooling air, that is, the labyrinth formed in this way is permeable to the cooling air, but at the same time prevents the refrigerated goods Rost trimfall down.
  • mutually overlapping longitudinal webs may be arranged on the opposite longitudinal sides of the adjacent, controllably movable floor elements, each forming a horizontal sealing gap that goes to zero, whereby the passage of cooling air in the area of rich between adjacent floor elements is prevented.
  • This horizontal seal works without scavenging air and it can be self-adjusting with the assistance of a spring force which always brings the horizontal sealing gap to zero.
  • the cooling grid of the bulk material cooler according to the invention over the length and across the width of the radiator is composed of several floor element modules, wherein thedeguttransporteurs successively arranged floor element modules are coupled such that the coupling elements of the successive floor element modules each one row in particular are claimed only on train.

Abstract

L'invention concerne un refroidisseur de matière en vrac, destiné notamment à du clinker chaud. L'objectif de l'invention est d'accroître la capacité de transport et le rendement de ce refroidisseur et de réduire les problèmes d'usure. A cet effet, la grille de refroidissement est constituée d'une pluralité d'éléments de fond (10 à 12) allongés, juxtaposés, s'étendant dans le sens longitudinal du refroidisseur. Ces éléments peuvent effectuer un mouvement de va-et-vient de manière commandée, indépendamment les uns des autres, entre une position 'aller' (13) et une position 'retour' (14), dans le sens de transport de la matière à refroidir, de sorte que cette dernière (15) est transportée progressivement à travers le refroidisseur selon le principe du fond mouvant alternatif (walking floor). Les éléments de fond (10 à 15) se présentent sous la forme de corps creux permettant le passage de l'air de refroidissement mais empêchant la matière à refroidir (16) de passer à travers.
