Abstract
The invention provides a high-purity quartz sand purification method. Two rotating roasting furnaces which are coaxially arranged are adopted, the two rotating roasting furnaces are obliquely arranged with the ground at an inclination angle of 20-30 degrees, the upper rotating roasting furnace is a pre-heating furnace, the lower rotating roasting furnace is a calcinator, and a discharging opening in the lower part of the pre-heating furnace is butted with a feeding opening in the upper part of the calcinator through a same connector. The temperature of the pre-heating furnace is between 750 DEG C and 800 DEG C, and the temperature of the calcinator is between 1000 DEG C and 1100 DEG C. Quartz blocks are fed in the pre-heating furnace through a continuous feeding device to be preheated, and then fed into the calcinator to be roasted. The roasted high-temperature quartz blocks fall into a water tank below the calcinator to be quenched by water, and the quenched material is conveyed to a vibrating table by a material conveying device to be sorted and purified. The steps of pre-heating and roasting are sequentially carried out, so that non-uniformity in heating of quartz blocks caused by uniform heating is avoided. The whole device adopts fully-automatic operation, the labor intensity is lowered, and the production efficiency is increased. The arrangement of the rotating roasting devices ensures great heating effect on the quartz blocks.
