Definitions
- the invention relates to a bulk material cooler with a cooled goods to be cooled such.
- Grate coolers are used in the stone and earth industry to the previously burned in an oven good such. As cement clinker or other mineral goods immediately afterwards cool down strongly on the cooling grate.
- the grate cooler are widely used, in which the grate system consists of a variety of alternately stationary and movable grate plate carriers, on each of which provided with cooling air openings and substantially flowed through from bottom to top of cooling air grate plates are attached. 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 the top of vertical drive plates aligned in the longitudinal direction of the radiator, which extend through corresponding 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 made up of a plurality of units extending in the longitudinal direction of the cooler arranged side by side elongated floor elements composed at least partially independently of each other between a Vorhubposition inchentransportides and a scrubhubposition are movable so that the goods to be cooled is gradually promoted by the cooler according to the Walking Floor conveying principle.
- the composite in this way cooling grate for the cooling air is permeable, which flows through the cooling grid and the bulk material bed mounted about in cross-flow from bottom to top, ie the bottom elements serve both as bulk material and asderostbel legislativeungs elements.
- the floor elements are moved together in their Vorhubterrorism forward, but not moved together in their return stroke together, but in at least two groups in at least two successive steps in succession, in which only a portion 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 bottom 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.
- a further feature of the invention may be arranged on the opposite longitudinal sides of the adjacent controlled movable floor elements each overlapping longitudinal webs each forming a horizontal sealing gap going towards zero, whereby the passage of cooling air in the area 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.
- the conveying mechanism for transporting the goods to be cooled is completely independent of the ventilation of the cooling grate.
- the movement of the floor elements individually or in groups can also be used to the bulk material such. B. to distribute the hot cement clinker on the cooling grid targeted.
- the cooling grid of the inventive Shen bulk material cooler of several, per module z. B. from three extending in the longitudinal direction of the radiator juxtaposed elongated approximately trough-shaped bottom elements 10, 11, 12 composed independently of each other between a Vorhubposition 13 indeguttransport therapies and a remindhubposition 14 are movable, so that the mounted on the floor elements and indicated in Figure 2 Refrigerated 15 is gradually promoted by the cooler on the walking floor conveying principle.
- the drive of the individual floor elements 10, 11, 12 of the floor element modules takes place from below the cooling grate via push frames, which are supported on rollers and on which working cylinders engage.
- the bottom elements 10, 11, 12 of all modules are formed as a hollow body, namely they have in cross section a the goods to be refrigerated 15 and the cooling air 16 from bottom to top permeable top and a spaced therefrom thedegut-Rost slidefall preventing underside 17.
- the lower sides 17 of all floor elements on a plurality of distributed over the length cooling air inlet openings 18 for the entry of the cooling air 16 for ventilation of the floor elements and cooling of the stored bulk material thereon.
- the tops of the floor elements may be provided with any perforations permeable to the cooling air 16.
- the tops of the longitudinally movable floor elements 10, 11, 12 each consist of spaced apart mirror image opposite, but offset from each other arranged saddle roof-shaped V-profiles 19, 20, the V-leg with space interlock, which last forms a labyrinth for the refrigerated goods 15 and for the cooling air 16. This ensures that the bulk material cooler according to the invention is secured against rust rusting.
- webs 21a, 21b, 21c lying perpendicular to the refrigerated goods transport direction are advantageously arranged for holding the lowermost bulk material layer and avoiding relative movement of this lowermost layer and the respective floor element, which contributes to the wear protection of these floor elements.
