DESCRIPCIONDESCRIPTION
Enfriador de sinter con disposicion de cierre hermetico hacia una camara desplazable que soporta el sinter.Sinter cooler with hermetic closing arrangement towards a movable chamber that supports the sinter.
La presente invencion se relaciona con un enfriador de sinter de una planta de sinterizacion para su uso en metalurgia, que comprende una camara de aire de enfriamiento y una camara de enfriamiento de sinter que incluye una placa base perforada o ranurada, que puede desplazarse sobre la misma, por ejemplo, por medio de ruedas de bogie que corren en un carril y que comprende un sello de gas de enfriamiento que incluye paredes de sellado inferiores, que se extienden entre la camara de aire de enfriamiento y la camara de enfriamiento de sinter cerca del eje de la rueda de la placa base.The present invention relates to a sinter cooler of a sintering plant for use in metallurgy, which comprises a cooling air chamber and a sintering cooling chamber that includes a perforated or grooved base plate, which can be moved over the same, for example, by means of bogie wheels running in a rail and comprising a cooling gas seal that includes lower sealing walls, which extend between the cooling air chamber and the near sinter cooling chamber of the wheel axle of the motherboard.
En dichos enfriadores de sinter, los elementos de sellado para el sellado de la brecha alrededor de los ejes de rueda de la placa base previamente han sido utilizados para evitar las perdidas de aire de enfriamiento. De esta manera, las perdidas del aire de enfriamiento que fluye desde la camara de aire de enfriamiento hacia la camara de enfriamiento de sinter ser deben reducir, de manera que mas aire de enfriamiento pase a traves de los orificios de la placa perforada, con el fin de mejorar el enfriamiento del material de sinter y reducir los costos operativos. El sello de aire de enfriamiento utilizado previamente es sometido a considerable desgaste, lo que involucra una renovacion frecuente de los elementos de sellado que se realiza de forma manual.In said sinter coolers, the sealing elements for sealing the gap around the wheel axles of the base plate have previously been used to prevent loss of cooling air. In this way, the losses of the cooling air flowing from the cooling air chamber to the sinter cooling chamber must be reduced, so that more cooling air passes through the holes of the perforated plate, with the in order to improve the cooling of sinter material and reduce operating costs. The previously used cooling air seal is subject to considerable wear, which involves a frequent renewal of the sealing elements that is done manually.
Es el objetivo de la presente invencion equipar un enfriador de sinter tal como se menciono anteriormente con un novedoso sello de gas de enfriamiento, el cual con una durabilidad incrementada reduce de forma segura las perdidas de aire de enfriamiento y, por consiguiente, la cantidad de aire de enfriamiento requerida, lo cual debera conducir a un ahorro en los costos operativos y a una mejora en la eficacia del enfriador.It is the objective of the present invention to equip a sinter cooler as mentioned above with a novel cooling gas seal, which with increased durability safely reduces cooling air losses and, consequently, the amount of required cooling air, which should lead to savings in operating costs and an improvement in the efficiency of the cooler.
En un enfriador de sinter tal como se menciono anteriormente, este objetivo en particular es solventado ya que el sello de gas de enfriamiento transportado junto con la camara de enfriamiento de sinter incluye placas de faldon internas y/o elementos de sellado externos cada uno insertado en las paredes de sellado, en donde la respectiva placa de faldon o el respectivo elemento de sellado encierra el eje de rueda de la placa base con ajuste seguro y se monta en la pared de sellado a fin de poder moverse libremente en relacion con el eje de la rueda de la placa base.In a sinter cooler as mentioned above, this particular objective is solved since the cooling gas seal transported together with the sinter cooling chamber includes internal skirt plates and / or external sealing elements each inserted into the sealing walls, where the respective skirting plate or the respective sealing element encloses the wheel axis of the base plate with secure fit and is mounted on the sealing wall in order to be able to move freely in relation to the axis of The motherboard wheel.
Debido a este tipo especial de la formacion y disposicion del sello de gas de enfriamiento, se propone un metodo de auto-compensacion para una proteccion confiable de los elementos de sellado, con el fin de evitar o reducir el desgaste de los mismos, lo que podria conducir a perdidas de gas de enfriamiento no deseadas.Due to this special type of formation and arrangement of the cooling gas seal, a method of self-compensation for a reliable protection of the sealing elements is proposed, in order to avoid or reduce the wear thereof, which It could lead to unwanted cooling gas losses.
Este objetivo en particular se logra cuando las placas de faldon y/o los elementos de sellado estan dispuestos para flotar libremente alrededor del eje de rueda de la placa base y absorber el movimiento del eje de rueda de la placa base.This particular objective is achieved when the skirt plates and / or the sealing elements are arranged to freely float around the wheel axis of the base plate and absorb the movement of the wheel axis of the base plate.
Los elementos de sellado dispuestos por fuera en particular se pueden hacer de neopreno.Sealing elements arranged on the outside in particular can be made of neoprene.
La respectiva placa de faldon puede tener un refuerzo de borde que descansa contra el eje de la rueda de la placa base y de manera preferible esta adaptado al espesor de la pared de sellado.The respective skirt plate may have an edge reinforcement that rests against the wheel axis of the base plate and is preferably adapted to the thickness of the sealing wall.
