Clay tile blank supporting and drying device

Abstract

The invention relates to a clay tile blank supporting and drying device, which comprises a roller type drying kiln and a tile blank support frame, wherein the roller type drying kiln comprises a roller and air delivery pipes, the roller is formed by arranging a plurality of roller bars, each roller bar is driven by a motor to rotate towards the same direction, the tile blank support frame is provided with a plurality of ventilating holes, and is provided with a boss according to the shape of a tile blank, the hot air is pressurized by a mechanical fan, the upper and lower surfaces of the tile blank are heated in a synchronous air convection way through the air delivery pipes, and then the air pressure at the surface of the tile blank is smaller than the air pressure in the tile blank. The clay tile blank supporting and drying device has the advantage that as the roller type drying kiln single layer control technology and the tile blank support frame horizontal type quick drying technology are adopted, the production cycle of clay tile is greatly shortened, and the product quality and production efficiency are improved.

Description

[0001] technical field

[0002] The invention relates to clay tile drying equipment, in particular to a clay tile blank support and roller table horizontal fast drying device.

[0003] Background technique

[0004] Since China has a history of making terracotta tiles, the drying process has been natural and slow drying. Before the 1960s, it was basically natural air-drying and sun-drying. It was fired vertically in an inverted flame kiln. This is the traditional Chinese pottery. watt. Later, people began to use waste heat to dry tile blanks, and tunnel-type multi-layer drying equipment came into being, which greatly improved production efficiency, and the drying time was reduced from more than 7 days to less than 60 hours. Then Japan had the tunnel-type multi-layer vertical drying technology, and Italy had the multi-layer tunnel-type drying production line. The drying time was more than 35 hours, and the maximum drying temperature was controlled below 80°C. The existing c...
