Technical Field

[0001] This utility model relates to the technical field of casting, and in particular to a magnetic separation device for a casting resin sand treatment system. Background Technology

[0002] Currently, the magnetic separation mechanism of the casting resin sand treatment system adopts both permanent magnet and electromagnetic magnetic control, which has a large magnetic penetration depth and strong magnetic force, making it an effective control point for the product.

[0003] Existing magnetic separation devices for casting resin sand treatment systems, such as the magnetic separation device for casting resin sand treatment systems disclosed in utility model patent application number 201920973618.4, mainly include a driven roller, a belt, and a magnetic yoke. The belt is wrapped around the two driven rollers with parallel axes, and the magnetic yoke is placed between the two driven rollers and inside the belt. In use, driven by a drive motor, the driven roller rotates, causing the belt to rotate. Affected by the sand mold carried on the belt, the lower edge of the upper section of the belt contacts the upper surface of the unpowered guide rod assembly.

[0004] However, existing magnetic separators suffer from uneven resin sand drop or excessively thick material layers, making it difficult to adsorb iron impurities in the lower layers, resulting in incomplete magnetic separation. Furthermore, the adsorbed impurities tend to accumulate, requiring regular manual cleaning, which leads to low work efficiency. Utility Model Content
