Background
Silica sand is typically stored in homogenization silos in many glass plants in the building materials industry. The chemical components and moisture of the silica sand fluctuate, and particularly, the moisture is influenced by external conditions such as production and transportation and is easy to fluctuate when entering a factory. In order to reduce adverse effects of moisture and chemical component fluctuation of the silica sand on production and batch quality, homogenization measures are taken in the storage process of the silica sand, so that the batch quality is favorably improved. High quality silica sand is an important guarantee for producing high quality float glass. And discharging the homogenized silica sand into an aggregate belt conveyor by a sand raking machine, and transporting the silica sand to a silica sand daily bin of a raw material workshop by the belt conveyor or other conveying equipment after screening by a sieve. The sieve is used for sieving and removing impurities (including mud lumps, large particles, frozen blocks and the like) brought in the silica sand transportation process, and if the impurities enter a rear-end production line, the impurities can cause defects of stones, defects and the like on the quality of finished glass.
The traditional silica sand screening of the homogenization silo generally adopts a vibrating screen, but the screen mesh of the vibrating screen has larger aperture, and a plurality of impurities are difficult to screen. In order to control the quality of silica sand in the glass factory, a plane sieve is generally selected for sieving the silica sand. The plane shaking screen has high screening efficiency, good screening quality and small screen mesh aperture, and is suitable for screening out impurities in silica sand; however, the screen area of a single plane shaking screen is small, the yield is low, generally, the yield of a single plane shaking screen is 30-40 t/h and is far less than the yield (more than 120 t/h) of a sand raking machine. Because the output of a single plane sieve shaker is lower, the output of the whole set of silica sand feeding system is correspondingly reduced, and the silica sand feeding time is greatly prolonged.
