A production process and curing
drying equipment for a solar
polycrystalline silicon quartz crucible solve the problem that the wall thickness of the existing
crucible is not uniform, the thermotechnical curing equipment cannot achieve the set process demands and the like. The production process is characterized in that the an organic
monomer is added in
quartz ceramic mud and a
crucible product is obtained after the
quartz ceramic mud is molded in a nonporous die; the process flow comprises the steps of melting a high-purity quartz
raw material, preparing the quartz
ceramic mud, pouring, solidifying and molding, curing and
drying,
sintering, detection, packing obtaining a finished product and storing in a warehouse. The
kiln body of the curing
drying equipment is of a three-layer structure, temperature measuring holes,
humidity measuring holes, pressure measuring holes, hot air regulating holes and observation
doors are arranged at two sides of a
kiln wall of each layer of roller
kiln; a circulation air pipeline, a hot air supplying pipeline, a damp air discharging pipeline and a cooling air pipeline are arranged above a
metal frame; distributed control is performed by adopting a full integration
automated control system, the
waste heat of the a kiln furnace is furthest used under the condition of ensuring the drying quality of the
quartz crucible product, and the aims of energy saving and cost reducing are achieved.
