Definitions
- the invention relates to a two-layer cooler with a Grate surface, according to the preamble of the claim 1.
- a two-layer cooler of the type mentioned above is known for example from DE-C-10 97 346.
- this known cooler is at the drain end Grating (cooler end) as a separating device for separating at least one of the upper and lower refrigerated goods layers mechanical shovel arranged with its cutting edge engages directly in the refrigerated goods and this in a divides upper and lower layers.
- the essential The disadvantage of such a design is the high mechanical and thermal wear, which the in the cutting edge immersed in hot refrigerated goods and thus also the Bucket is exposed. This results in the known execution a considerable amount of maintenance and also a very undesirable susceptibility to failure.
- the invention is therefore based on the object Two-layer cooler in the preamble of claim 1 assumed type so that in the area of Separation device the freedom from maintenance and fault safety of the cooler can be significantly improved.
- This object is achieved in that at the cooler end as a separation device for separating the top and bottom refrigerated goods layer a stationary goods zone is provided, which is connected upstream of the crusher, flat inclined chute-like guide surface is.
- the separation device not by a separate mechanical element, but formed by a resting zone of the refrigerated goods is also affected in the area of the separating device inevitable wear alone between good particles moving relative to each other.
- abrasion is - unlike wear and tear mechanical cutting edge or shovel - by no means annoying, since the resulting fine particles be carried away with the finished goods and the dormant Goods zone automatically from the newly supplied material flow regenerated.
- FIG. 1 in a schematic overall view Two-layer cooler is used as a moving grate cooler formed, with successive rows of plates 1, 2 are arranged alternately stationary and movable.
- the plate rows of the cooler are divided into several groups 3, 4, 5 summarized, the separate fans 6 and 7 or 8, 9 with cooling air.
- a lower layer 10 is already on Pre-cooled goods to be cooled on the grate surface of the cooler given up.
- On this lower layer 10 is an upper Layer 11 of hot refrigerated goods applied.
- the pre-chilled Chilled goods of the lower layer 10 are placed over a Shaft 12 fed by a bunker wall 13 from a shaft 14 is separated, through which the hot Refrigerated goods - for example coming from a rotary kiln - applied to the lower layer 10 of the two-layer cooler becomes.
- a crusher 16 is furthermore arranged at the cooler end, which is connected upstream of a chute 17, which is the good of top layer 11 feeds the crusher 16.
- This chute 17 is inclined so flat that there is one on it dormant goods zone 18. It provides a separation device represents layers 10 and 11 at the end of the cooler separates from each other by dividing the good of the lower Retains layer 10 and into the finished goods shaft 15 conducts while the material of the upper layer 11 over the dormant goods zone 18 can slide away, so that it to Breaker 16 arrives.
- the crusher 16 coarser parts of the good crushed upper layer 11. After passing the crusher 16 the material of the upper layer 11 arrives as circulating material back to the beginning of the cooler (conveyor line 19) and is there as the lower layer 10 on the grate surface of the Abandoned cooler.
- the lower end of the finished goods chute 15 opens out Distance over a storage area 20 from a horizontally arranged table is formed. Its dimensions and its distance from the lower end of the finished goods chute 15 are chosen so that the bulk cone 21a of the finished goods emerging from the finished goods chute 15 21 on the surface of the storage surface 20 forming table opens into the edges of the table.
- a discharge member 22 is located in the storage surface 20 Direction of the double arrow 23 to and fro.
- the stroke speed and the stroke length of this as a bar trained discharge member 22 are changeable.
- the entrance opening of the finished goods chute 15 at the top is formed by a sieve or grate Classifier 24 covered.
- the finished goods chute 15 extends over the entire Width of the cooler (see Fig. 3). Its cross section widens towards the bottom (see Fig. 2).
- the grate plates are movable Plate rows 2 from a swing frame 25 worn, the back and forth in the direction of the double arrow 26 is movable while the plates of the rows of plates 1 are fixed.
- the last movable plate row 2a in the conveying direction is arranged so that it covers the area of the classifier 24 at least partially covered.
- the movable rows of plates 2 can in sections be connected to a channel that connects to the Swing frame 25 moves and a sliding seal is supplied with air.
- the lower layer 10 of pre-chilled goods protects the grille surface of the cooler from too high thermal stress and heavy wear by the hot refrigerated goods that form the upper layer 11.
- the two layers are covered by of the stationary goods zone 18 from each other Cut.
- a change in the strength of the top and lower layer is by adjusting the altitude the separator possible.
- the height of the resting goods zone 18 (and thus the thickness of the lower layer 10) by reduction the inclination of the chute 17 can be increased (and vice versa).
- Influencing the relative Layer thickness can also be increased, for example or lowering the chute 17 (with the same Chute inclination).
- Classifier 24 holds larger chunks of material, that are present in the lower layer 10. These chunks are then either autogenous Crushing in the material of the lower layer above the classification device 24, or they get into the dormant goods zone 18 or in the upper layer 11. Im in the latter case they pass crusher 16 again.
- the finished goods 21 jams on the storage surface 20 because the bulk cone 21a on the surface of the storage surface 20 forming tables within the table edges flows. Regardless of the existing one - in operation possibly changing - grain composition of the finished goods 21 is therefore the discharged amount of goods exclusively by the lifting speed and the Stroke length of the discharge member 22 determined.
- the last movable plate row 2a of the cooler has extended push edges so that the sieve bars of the Classifying device 24 completely or partially covered will. This will work even when using large attachments always get into the area of the classification device 24 at least the one through the last movable row of plates Keep the swept area clear during the return stroke. This area is so large that the quantity of material from the lower layer 10 passes through.
- the screening rods of the classification device 24 prevent that large pieces of good get into the finished goods chute 15. This way, constipation between the lower end of the finished goods chute 15 and the Storage surface 20 forming table avoided.
- the discharge member 22 designed as a bar becomes mechanical or hydraulically driven. It is convenient protected against wear by cast elements.
- the two partial flows of the finished product 21, which by the Discharge member 22 are conveyed away from the storage surface 20, can either - as indicated in Fig.1 - to a common conveyor line 27 summarized or separately to be transported further.
- FIG 5 shows a practical embodiment in a variant of the devices downstream of the crusher 16 for the discharge of the goods in circulation (i.e. the goods the upper layer 11).
- the crusher 16 is followed by a sieve grate 30, the Passage openings are dimensioned such that chopped goods are passed through the sieve grate, larger foreign objects (e.g. broken ones Rings of the crusher 16) are held back.
- larger foreign objects e.g. broken ones Rings of the crusher 16
- a chute 31 connects to the sieve grate 30, the one is the material in circulation (conveyor line 19 according to FIG. 1) a main outlet 32 feeding a transport device and two bypass outlets 33, 34. Through the latter two bypass outlets 33, 34 can be selected Cooled goods of the upper layer 11 are removed as finished goods will. It then arrives according to the conveyor line 28 (according to Fig.1) in the conveyor line 27 of the finished goods.
- the three outlets 32, 33 and 34 are through slide 35 up to 37 can be released or locked.
- the bypass outlets 33, 34 are also emergency routes Failure of a transport device for the circulating goods.
- bypass outlets 33, 34 are basic closed.
- the slides 36, 37 are opened and the slider 35 closed, the cooler can, if desired also operate in one shift.
- the property is erased into this case in the chute 31 as by the Good cone 38 indicated.
