The invention provides a
continuous production apparatus of a
microcrystalline heat insulation particle. The apparatus comprises a
raw material bin, a preheating furnace, a
kiln, a cooler and a finished product bin which are sequentially connected, a
raw material is preheated by the preheating furnace and then is conveyed into the
kiln through a tubular chain lifter, the
kiln comprises a furnace body, a feeding bin is arranged at the upper end of the furnace body, a discharging port is arranged at the lower end of the furnace body, the furnace body comprises an expansion section and a
vitrification section, a discharging device is arranged in the expansion section of the furnace body, the discharging device comprises at least one set of funnel and conical bucket, and the preheated sands are dispersed and gathered through the inner walls of the funnel and the cone; and the furnace body is symmetrically provided with a plurality of sets of burners. The
perlite ore sands are dispersed andthen gathered in the furnace body, so the discharging time is delayed, and the expansion heat
absorption time of the preheated sands is prolonged to ensure sufficient heat absorption and reach a expansion temperature; and the
microcrystalline heat insulation particle wrapped with a
smooth surface and having a cavity structure is produced through the apparatus, and the heat insulation particle hasthe advantages of no water absorption, high strength and excellent heat insulation performance.
