Description

Technical Field

[0001] This utility model relates to the field of quartz sand magnetic separation technology, and in particular to a modular quartz sand magnetic separation device that is easy to maintain. Background Technology

[0002] Quartz sand is quartz particles produced by crushing and screening quartz stone. Quartz stone is a non-metallic mineral, and its main mineral component is silicon dioxide (Si). Quartz sand can be classified by quality into ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused quartz sand, and silica powder, etc. Quartz sand is a diamagnetic material and cannot be magnetized in a magnetic field, while impurity minerals such as magnetite, hematite, limonite, and biotite are magnetic. Taking advantage of this difference in properties, magnetic impurity minerals and quartz sand particles enriched with a large amount of iron-oxygen minerals inside or on the surface of the particles can be removed from quartz sand ore by magnetic separation.

[0003] Currently, during the magnetic separation process of placing a large amount of quartz sand material into the feed trough of a quartz sand magnetic separator, due to the small particle size of the quartz sand, some of the quartz sand inevitably contains a certain amount of moisture. Furthermore, when the quartz sand is piled up in the feed trough, it is subject to vibration and external forces, causing some material to easily adhere to the inner wall of the feed trough. Prolonged accumulation can affect the smoothness of material processing within the feed trough, requiring regular internal maintenance. However, existing magnetic separation equipment is time-consuming and labor-intensive to open the top cover, which is opened with bolts. The operating space after opening the top cover is relatively small. Furthermore, once a large top cover is opened, multiple top covers need to be operated during disassembly and reassembly, resulting in low operating efficiency and inconvenience for regular internal maintenance. Therefore, this utility model provides a modular quartz sand magnetic separation device that is easy to maintain. Utility Model Content
