Description

Technical Field

[0001] The utility model belongs to the technical field of quartz sand, in particular to a quartz sand grading and screening device which is convenient for replacing the screen. Background Art

[0002] Quartz sand is a non-metallic mineral. It is a hard, wear-resistant, chemically stable silicate mineral. Its main mineral component is SiO2. The color of quartz sand is milky white or colorless and translucent. The hardness is 7. Quartz sand is an important industrial mineral raw material and a non-chemical hazardous substance. It is widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical solvents, metallurgy, construction, chemicals, plastics, rubber, abrasives and other industries.

[0003] According to a disclosed quartz sand screening device (publication number: CN209061527U), it includes a main body shell, a hopper and a support frame. The hopper is arranged inside the main body shell, and the support frame is arranged below the hopper. A material receiving port is opened on the side wall at the bottom of one side of the main body shell, and a material discharge port is arranged above the material receiving port. The material discharge port is welded on the side wall of the main body shell, and the material discharge port is connected with the interior of the main body shell. A limiting frame is sleeved on the outer wall of the outer side of the hopper. However, in the above device, it is difficult to achieve the effect of accelerating the speed of quartz sand screening by vibration of the filter plate through the mutual cooperation of components such as the main body shell, the hopper and the support frame, and it is difficult to prevent the filter plate from being blocked, which reduces the screening efficiency, increases the maintenance cost, and reduces the operability and reliability of the equipment, which needs to be improved.
