Abstract
Description
Dispositivo de fijación de bloques de sobresolera para vagonetas de hornos túnel.Block fixing device envelope for tunnel kiln cars.
La presente invención se refiere a un dispositivo de fijación de bloques de sobresolera para vagonetas de hornos túnel, del tipo de los que están ensamblados entre sí formando la superficie de sobresolera. Particularmente, el dispositivo de la invención es ventajosamente aplicable para unir los bloques de soporte mediante un "puente" o perfil cuya sección transversal sea como la letra Pi (la letra griega \pi).The present invention relates to a device for fixing block of overlays for wagons tunnel ovens, of the type that are assembled together forming the surface of envelope. Particularly, the device of the invention is advantageously applicable for joining the support blocks by means of a "bridge" or profile whose cross section be like the letter Pi (the Greek letter \pi).
En la industria cerámica, el soporte y transporte de las piezas en curso de fabricación suele efectuarse sobre unas vagonetas que se desplazan por la planta productiva, sobre las cuales acceden y son sometidos a las diferentes fases del proceso. Encima de la solera de las vagonetas se dispone normalmente una sobresolera, hecha de bloques de refractario, que soporta las piezas en curso de fabricación, apiladamente en una o varias capas.In the ceramic industry, the support and transport of parts in the process of manufacturing is usually done on some wagons that move through the production plant, on which they access and are subjected to the different phases of the process. Above the floor of the wagons is normally arranged an envelope, made of refractory blocks, that supports the parts in progress, stacked in one or more layers.
Son ya conocidos los bloques de soporte de forma primática de sección en forma de letra Pi, comprendiendo dos tabiques laterales y una porción puente que los une. Estos bloques son normalmente macizos o contienen orificios para facilitar la circulación del aire y, por lo tanto, producir una mejor disipación del calor desde las piezas cerámicas en contacto con la sobresolera.The shape support blocks are already known sectional elementary in the form of letter Pi, comprising two lateral partitions and a bridge portion that joins them. These blocks they are normally solid or contain holes to facilitate air circulation and therefore produce a better dissipation of heat from the ceramic pieces in contact with the It stands out.
También es de uso común el empleo de placas lisas de material refractario, que se disponen en pilares apoyados directamente sobre la solera. Este tipo de distribución no resulta muy estable, por estar todas las piezas apoyadas entre sí, pero en ningún caso fijadas las unas con las otras constituyendo un solo bloque. Por consiguiente, es habitual que la estructura se desmonte o desmorone, al menos parcialmente, debido a las etapas de carga y descarga del material cerámico, o a las dilataciones y contracciones del material de la sobresolera.The use of plates is also commonly used smooth of refractory material, which are arranged on supported pillars directly on the hearth. This type of distribution is not very stable, because all the pieces are supported by each other, but in no case fixed with each other constituting a single block. Therefore, it is customary for the structure to be disassembled or crumble, at least partially, due to the loading stages and discharge of ceramic material, or to dilations and contractions of the envelope material.
En bloques de refractario, los dispositivos de fijación que se basan en adhesivos no resultan una buena solución, porque dichos adhesivos no permiten las dilataciones diferenciales de los dos materiales a unir.In refractory blocks, the devices of fixing based on adhesives is not a good solution, because said adhesives do not allow differential expansion of the two materials to join.
Este problema queda resuelto con el objeto de la presente invención.This problem is solved for the purpose of present invention
El dispositivo de fijación de bloques de sobresolera con una sección transversal formada por dos tabiques y un elemento de puente que los une, estando dichos bloques dispuestos uno encima del otro con sus tabiques enfrentados, de la presente invención está caracterizado esencialmente por estar compuesto de varias partes de fijación cilíndricas o prismáticas, adaptadas para encajar en sendas muescas u orificios complementarios practicados en respectivos bloques contiguos, de modo que dichos bloques contiguos ensamblados quedan impedidos de sufrir movimientos de desplazamiento y/o giro relativamente grandes, uno respecto del otro, permitiendo sin embargo las dilataciones diferenciales de los materiales ensamblados.The block fixing device of envelope with a cross section formed by two partitions and a bridge element that joins them, said blocks being arranged one on top of the other with their facing partitions, of the present invention is essentially characterized by being composed of several cylindrical or prismatic fixing parts, adapted for fit into notched paths or complementary holes made in respective adjoining blocks, so that said blocks contiguous assemblies are prevented from suffering movements of relatively large displacement and / or rotation, one with respect to other, however, allowing differential dilatation of assembled materials
Según otra característica de la invención, dichas piezas de fijación están constituidas por tubos huecos, o por varillas o espigas, preferentemente de sección transversal similar a la de las muescas u orificios practicados en los bloques ensamblados, de modo que quedan introducidos con escasa holgura en dichos orificios o muescas.According to another feature of the invention, said fixing parts consist of hollow tubes, or by rods or pins, preferably of cross section similar to that of the notches or holes made in the blocks assembled, so that they are introduced with little slack in said holes or notches.
A continuación se hace una descripción de una forma de realización particular, no limitativa, del dispositivo de fijación objeto de la presente invención, para cuya mejor comprensión se acompaña de unos dibujos a título de ejemplo, en los cuales:Below is a description of a particular, non-limiting embodiment of the device fixation object of the present invention, for whose best understanding is accompanied by some drawings by way of example, in the which:
