Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand drum screening, in particular to high-precision quartz sand drum screening equipment. Background Art

[0002] Quartz sand is quartz particles made by crushing quartz stone. It plays an important role in the field of industrial manufacturing. As an important industrial mineral raw material, quartz sand is not only widely used in metallurgy, construction, plastics, abrasives and other industrial industries, but also plays an important role in water treatment agent filter materials. The uses of quartz sand with different particle sizes are also different. Quartz sand refers to the particle size or coarseness of quartz sand by mesh number. Usually, various multi-level vibrating screens are used to screen quartz sand of different mesh numbers. Among the existing various vibrating screens, Square vibrating screens are widely used. Their working principle is as follows: the sieve plates of each layer are parallel and inclined. Quartz sand falls from the feed port to the upper end of the uppermost sieve plate, and then slides down the upper surface of the sieve plate through the vibrator and the weight of the quartz sand. During the sliding process of the quartz sand, quartz sand with a diameter smaller than the sieve hole diameter falls to the next sieve plate when passing through the sieve hole, and quartz sand with a diameter larger than the sieve hole diameter continues to slide to the tail end of the sieve plate of this layer through the sieve hole until it slides out of the discharge port. The existing quartz sand drum screening equipment has low screening efficiency and poor practicality. Utility Model Content
