Abstract
A continuous elongate ceramic article manufacturing system capable of continuously manufacturing elongate ceramic articles having a predetermined length by continuously extruding a clay material containing clays as the principal components in a hollow or solid continuous strip, drying the continuous strip in a short time, firing the dried continuous strip, and cutting the fired continuous strip in the predetermined length. The system comprises a continuous arrangement of an extruder, a drying machine, a cutter, and a firing furnace arranged in that order, or a continuous arrangement of an extruder, a drying machine, a firing furnace, and a cutter arranged in that order.
Claims16
A continuous elongate ceramic article manufacturing system comprising a sequential linear arrangement of:
- an extruder having a nozzle which continuously extrudes a material clay containing clays as principal components;
- a drying machine for drying a continuous strip extruded by the extruder;
- a moving cutter for cutting the continuous strip delivered from the drying machine into dry elongate plates having a predetermined length;
- a conveying machine for conveying the dry elongate plates;
- a firing furnace which continuously preheats, fires and cools the dry elongate plates;
- and
- a delivering machine which delivers the fired elongate plates delivered from the firing furnace to the next process,
- characterized in that the nozzle of the extruder is provided with a hollow lattice core for forming hollows within the continuous strip, and one or a plurality of pipes corresponding to the number of legs of the lattice of the lattice core are attached to the front or rear part of the lattice core to circulate gaseous fluid through the hollows of the continuous strip in the direction of movement of the extruded continuous strip.
A continuous elongate ceramic article manufacturing system comprising a linear arrangement of:
- a vacuum extruder which continuously extrudes a clay material containing clays as the principal materials, in a continuous strip;
- a heating machine which dries the continuous strip by infrared rays;
- a drying machine which dries the continuous strip delivered from the heating machine;
- a firing furnace which fires the continuous strip delivered from the drying machine;
- a moving cutter which cuts the fired continuous strip delivered from the firing furnace into elongated ceramic plates having a predetermined length;
- and
- a delivering machine which delivers the elongate ceramic plates formed by cutting the fired continuous strip by the moving cuter;
- characterized in that the nozzle of the extruder is provided with a tubular lattice core for forming a hollow in the longitudinal central portion of the continuous strip and a ventilating pipe connected to external equipment at one end is connected at the other end to the tubular lattice of the tubular lattice core at a position near the inlet thereof for forcing gaseous fluid through the hollow in the continuous strip in the direction of movement of the extruded continuous strip.
