Description

Technical Field

[0001] The utility model relates to the technical field of ceramic tile production, in particular to a tunnel kiln circulation production system. Background Art

[0002] In the production of ceramic tiles, the green tiles need to be fired in a tunnel kiln. The green tiles are generally transported to the tunnel kiln by kiln cars for firing. In actual production, workers stack the green tiles on the kiln cars, then push the kiln cars loaded with green tiles into the tunnel kiln for firing. After firing, the tiles are unloaded from the kiln cars and stored. The empty kiln cars then return to the loading area along the same route to stack the tiles. Since the kiln cars use the same track for loading and unloading, they also need to occupy the track during the empty return journey, which makes continuous production impossible, and is not conducive to improving production efficiency and shortening the production cycle. In addition, most existing kiln cars use a flatbed structure, which cannot provide good protection for the green tiles during transportation and can easily cause damage to the green tiles.
