Definitions

  • the invention relates to a two-layer cooler in which the goods to be cooled on a cooling surface from the start of the cooler to The cooler end is moved, being in a first feed zone an upper layer of hot at the beginning of the cooler Chilled goods on a lower layer of pre-chilled Chilled goods are given and at the end of the cooler the two Layers separated by a separator be separated, with the goods of the lower layer as Finished goods removed and the goods of the upper layer through a transport device as a circulating good to a the second feed zone at the beginning of the cooler and placed there as the lower layer on the cooling surface becomes.
  • a two-layer cooler of the type mentioned above is known for example from DE-C-10 97 346.
  • Such a cooler has the advantage that the cooling surface, for example, from individually ventilated grate plates and / or rows of grate plates, thermal is protected by pre-cooling the lower layer and acts as a protective layer.
  • DE-U-527 173 discloses a drying device and, if necessary, pre-firing granulated primary material for the production known from cement.
  • This device contains a first hopper, over the fresh produce as bottom layer is applied to a grate. Behind this first hopper is a second hopper arranged, the returned good on the applies the lower layer of the fresh material.
  • An adjustable drainage chute is provided, which part of the goods to the second hopper leads back and derives the other part of the good.
  • the invention has for its object a To design two-layer coolers of the type mentioned in the introduction that the efficiency of the cooler improves becomes.
  • the embodiment of the invention is thus during the operation of a uniform height of the lower Layer ensures that on the one hand a relative uniform cooling effect is achieved and on the other hand the separator for separating the lower and upper Layer can be fixed.
  • the baffle and the cooling surface can, according to the Grain of the goods to be cooled, an optimal height of the lower layer can be set. So requires fine-grained Well a thinner lower layer than a coarse one Good.
  • 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 of already chilled goods abandoned the grate surface of the cooler.
  • On this lower one Layer 10 becomes an upper layer 11 of hot refrigerated goods upset.
  • the pre-chilled goods of the lower Layer 10 is fed via a shaft 12 which through a storage or bunker wall 13 from a shaft 14 is separated, through which the hot refrigerated goods - for example coming from a rotary kiln - on the lower layer 10 of the two-layer cooler abandoned becomes.
  • a finished goods shaft 15 is provided.
  • a crusher 16 is arranged there, the one Chute 17 is connected upstream, which is the good of the upper Layer 11 feeds the crusher 16.
  • This chute is 17 thereby inclined so flat that there is a resting one on it Training zone 18. It provides a separation device represents the layers 10 and 11 from each other at the cooler end separates by separating the material from the lower layer 10 withholds and conducts into the finished goods well 15 while the good of the upper layer 11 over the dormant Gutzone 18 can slide away so that it to the crusher 16th reached.
  • 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 exiting from the finished goods chute 15 Finished goods 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 baffle 13 is in the area between the first goods supply zone (Shaft 12) and the second feed zone (Shaft 14) arranged, between the lower edge and a distance a is provided from the cooling surface, which corresponds to the height of the lower layer 10.
  • 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 bottom layer is by hiring the Height of the separator possible. For example the height of the dormant goods zone 18 by reducing the inclination of the chute 17 can be increased (and vice versa).
  • the most Classification device provided at the top of the finished goods chute 15 24 holds larger chunks of good in the lower layer 10 are present back. These chunks of good are then subject to either an automatic Comminution in the material of the lower layer above the Classifier 24, or they go to the dormant Good zone 18 or in the upper layer 11. In the latter If they fall, they pass crusher 16 again.
  • the finished goods 21 jams on the storage surface 20, so that bulk cone 21a on the surface of the storage area 20 forming tables within the table edges flow out. Regardless of the existing one - in operation Possibly changing - grain composition of the Finished goods 21 therefore become the discharged good quantity exclusively by the lifting speed and the Stroke length of the discharge member 22 determined.
  • the baffle 13 consists essentially of a Support beam 30 trained support element and arranged above Bracket elements, both on the Shaft 12 as well as on the shaft 13 facing Provide side with a fireproof brickwork 32 are.
  • the support beam 30 extends over the entire Width of the cooling surface and is in side walls 33a and 33b of the cooler.
  • the support beam 30 is on the three with the refrigerated goods in Side surfaces coming into contact with protective segments 34, 35 and 36 provided. That of the second feed zone, i.e. the protective segment 34 facing the shaft 12 has a height determining the lower layer 10 Scraper edge 34a. In contrast, this is the first Goods supply zone, i.e. the shaft 14 facing protection segment 36a as open at the top, for receiving Chilled goods are formed in the groove, the front boundary surface 36a much lower than that with the rear boundary surface connected to the support beam 30 36b is formed. Protection segments 34 and 35 on the other hand, are essentially flat Plates trained.
  • the individual protection segments 34, 35, 36 are preferred Made of wear-resistant cast and in a suitable Way supported on the beam 30.
  • the bracket can consist, for example, that the one piece or several parts Protection segments in a dovetail guide on the Support beams 30 are pushed on.
  • the baffle 13, d. H. the support beam 30 and the bracket members 31 with a suitable one Cooling coolant, for example cooling air.
  • a suitable one Cooling coolant for example cooling air.
  • the support beam 30 a cooling air inlet opening 37 and the top bracket member 31 a cooling air outlet opening 38.
  • the cooling air is preferably meandering (arrows 39) through the support beam and the support elements.
  • the protection segment continues 36 formed channel with through the shaft 14 falling good too. This forms an oblique to the Cooling surface inclined surface, on the other, to be cooled, hot material can hit and slide off. On in this way the friction takes place essentially within of the refrigerated goods instead, so that the support beam 35 and also the protective segment 36 from wear and excessive Are protected from heat.
  • the individual protection segments are preferably interchangeable attached to the support beam, so that in particular the protective segment 34 is replaced with its stripping edge 34a can be. Protection segments can therefore also be used 34 are used, the stripping edge 34a have a smaller distance to the cooling surface, such as which is indicated by dashed lines in Fig.2. In this way, the height of the lower layer 10 can increase the goods to be cooled are adjusted to an optimal To achieve cooling effect. So requires fine-grained goods a thinner lower layer 10 as a coarse grain.
