The mobile tunnel kiln arranges the production activities of the four main processes of laying, drying, roasting and discharging the brick after forming the wet blank body in the ring kiln road in a compact manner, and moves with the ring kiln body in a sequential cycle. In the production line of this process design, except outside the tunnel kiln, the equipment and production activities of other processes are carried out in the environment without maintenance walls around, without heating and insulation facilities, and basically in the outdoor natural environment. Only a rain-proof and sun-proof kiln canopy is set on the top of the kiln tunnel.
During the northern winter frost, the mud in the conveyor, mixer and brick machine of this production line will freeze hard and become unproductive. In particular, the wet blank placed in the ring kiln road, to stop in the outdoor for a long time, to enter the dry part, has been frozen hard can not be used, must stop production and close the door. Is near the frost period before, after the low temperature of the time, even if the wet billet did not freeze, but the production output and product quality will be affected.
Affected by the cold climate in the north, the production line of various sintered bricks only works for 7 to 10 months each year, so the total output of the year is greatly reduced. This has become a refractory refractory brick production line.
Xi 'an Liyuan after years of research: the use of fully enclosed plant, after the practice of Hebei Province, Shaanxi Province and other places, can fully meet the "mobile tunnel kiln" year-round non-stop operation, greatly improve the production efficiency. From now on, the mobile tunnel kiln can be used safely in the northern winter.
