Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of silica sand screening, especially to a silica sand continuous screening device. BACKGROUND

[0002] Silica sand, also known as quartz sand, is a non-metallic mineral aggregate with quartz as the main mineral component. It is a sand particle processed by crushing quartzite, and its main component is silicon dioxide, and other impurities include iron, aluminum, calcium, and magnesium oxides. Silica sand has relatively high hardness and density, which makes it have good wear resistance and chemical stability. These characteristics make silica sand widely used in many fields.

[0003] The working principle of the silica sand continuous screening device is as follows: the silica sand to be screened is continuously fed into the screening device through the feed inlet. The driving device is started to drive the screen to vibrate. The silica sand particles on the screen are subjected to the action of the vibration force and start to be screened. The silica sand particles smaller than the screen aperture fall to the lower layer and become undersize material, which is discharged from the corresponding discharge outlet. The silica sand particles larger than the screen aperture continue to roll and jump on the screen and are finally discharged from the discharge outlet, completing the screening work.

[0004] However, the inclination angle of the screen of the existing silica sand continuous screening device cannot be adjusted, so it cannot be adjusted according to the diameter of the silica sand and the screening requirements. In addition, during use of the existing silica sand continuous screening device, the screen holes are often blocked and need to be cleaned manually by the staff using a brush, which is low in efficiency and time-consuming and laborious, greatly affecting the screening efficiency of the device.
