The utility model relates to the technical field of
quartz sand baking equipment, in particular to a
roasting device for
quartz sand production, which comprises a
roasting horizontal tank, a heating component which is arranged along the axis of the
roasting horizontal tank and is independent of the roasting horizontal tank and sleeved with the roasting horizontal tank, a feed port is arranged on the upper portion of a tank body at one end of the roasting horizontal tank, and a feed hopper is arranged at the feed port. A filter
sieve is arranged in the feeding hopper, a discharging port is formed in the bottom of a tank body at the other end of the horizontal roasting tank, a sliding slope is arranged on the bottom wall of the tank body of the horizontal roasting tank in a downward inclined mode in the direction from the feeding port to the discharging port, a high-pressure air inlet
assembly is arranged on one side of the top end of the sliding slope, and high-pressure
inert gas enters the horizontal roasting tank, so that
quartz sand is effectively blown and turned over. The quartz sand is uniformly heated and treated in the roasting process, and the surface of each quartz sand can be in full contact with high-temperature
airflow, so that the roasting efficiency and effect are improved. And meanwhile, the liquid quartz sand is effectively guided to flow from the feed port to the
discharge port, the quartz sand is prevented from being retained or accumulated in the tank body, and the effects of uniform heating and good rolling are achieved.
