Definitions

  • the invention relates to a device for cooling materials, such as cement clinker, which are conveyed to grates, through which a cooling medium flows, and which are produced in rotary furnaces.
  • Grate coolers are built as traveling grates or as sliding grates with grate rows that can move against each other.
  • DE patent applications 31 31 514.3 and 31 48 792.0 propose measures for better air guidance and distribution in the bulk material. In particular with high grate beds to achieve high heating de cooling air, high demands are placed on the grate for uniform distribution of the cooling air into the bulk material above, while at the same time high pressures of the cooling medium must be built up.
  • the invention is therefore based on the object of distributing the cooling air to the bulk material, particularly at a high level Bulk material bed, so as to increase the degree of recuperation.
  • the segregation of the coarse and the fine fraction of the bulk material, which is mainly discharged from rotary kilns, must be taken into account.
  • the task can be solved in a particularly advantageous manner with stationary and continuously smoothly laid grate plates and a drag chain sliding thereon.
  • These stationary grate plates which can be perforated metal strips laid across the radiator width, for example, can be sealed much better with each other and against the support than was previously possible with moving grate plates. This allows the grate to be technically advantageously provided with a high resistance which is effective for the uniform distribution of the air.
  • the individual chamber partitions for the cooling air under the grate can be sealed better against the stationary grate and thus with each other.
  • throttle or pulsation flaps can be arranged close under the stationary grate plates in order to have a direct influence on the air distribution.
  • the stationary grate plates can be of any desired strength and support at the desired location in order to absorb refractive forces on the grate.
  • two or more conveying means - preferably it is an endless chain stair chain conveyor - arranged side by side. This means that for the purpose of better air distribution, a low fine fraction bed can be set in addition to a high bed made up of mostly coarse fraction.
  • Conventional grate coolers usually have a drag chain especially for collecting and removing the grate diarrhea.
  • this rust fallout from the return of the endless conveying means - preferably also a drag chain - can be collected and possibly returned to the rust.
  • the known advantages of an increasing or a falling arrangement of the grate in the conveying direction can also be easily achieved with the stationary grate with drag chain.
  • the bulk material is drawn out from under an elevated material bed in the area of the task for the purpose of equalization across the grate width.
  • the bulk material transport is supported by the slope and can take place in a particularly advantageous and expedient manner against a stowage device, i.e. the promotion according to the invention takes place in combination with the accumulation of the upper layer or layers of the bulk material.
  • the grate must be acted on in the conveying direction in a carefully graded manner with the cooling air required.
  • this gradation is achieved in a particularly simple manner by means of adjustable openings in the stationary grate.
  • two grate plates lying one on top of the other with the same perforation or slit are provided for the passage of the cooling medium, of which the lower plate can be moved against the upper plate, so that the openings for the passage of the cooling medium can be partially or completely closed by shifting.
  • the figure shows a longitudinal section through a horizontal drag chain cooler with inlet shaft 1, end wall 2, dammed bed 3, extended bed 4, baffle wall or crushing jaw 5, drag chains 6, deflection and drive stars 1, stationary grate 8, the air chambers 9, 10 , 11 and the associated fans 12, 13, 14.
  • the stationary grate 8 rests on the grate supports 15, which are arranged particularly closely in the area of the air chamber 10 under the baffle and crushing jaw 5.
  • the grate diarrhea is conveyed back and around the deflection star 7, which is designed as a covered drum.
  • the grate through can also be conveyed to the upper run with a small bucket elevator, which is not shown, and from there back into the ventilated cooler. Seal air 18 is blown into the antechamber 17.
  • the cooled and already broken clinker is discharged onto a cross conveyor 19.

Abstract

Dans une installation de refroidissement de marchandises en vrac, par exemple de clinker, sur des grilles traversées transversalement au moyen d'air de refroidissement, on vise à améliorer la distribution de l'air de refroidissement sur la marchandise en vrac et à tenir compte de la ségrégation de la partie grossière et de la partie fine de la marchandise en vrac. Dans ce but, la marchandise en vrac (3) est amenée sur une grille stationnaire (8) grâce à un moyen de transport mobile situé directement au-dessus. Afin de rendre la grille (8) assez stable pour accepter les forces de concassage et de permettre ainsi de concasser l'agrégat sortant du four au moyen d'une mâchoire de concasseur (5) contre la grille, afin de mieux le refroidir et de mieux le déverser, on peut prévoir comme moyen de transport une chaîne à drague sans fin (6) dotée d'entraîneurs conçus pour le transport et pouvant être combinée avec une installation de refoulement destinée à refouler les couches supérieures de la marchandise en vrac.
