AI Technical Summary
Technical Problem
In existing technologies, active metals and alloys are easily oxidized in the molten state, leading to nozzle system blockage. Furthermore, single-layer foam ceramic filters have poor filtration effects and cannot effectively remove oxides and impurities.
Method used
It adopts a multi-layer foam ceramic filter structure with the mesh diameter decreasing from top to bottom. Combined with the detachable connection design, it achieves graded filtration and ensures that the nozzle is not easily clogged.
Benefits of technology
It significantly improves the purity of the alloy melt, reduces the risk of nozzle clogging, and enhances the efficiency and filtration effect of the equipment.

Abstract
The utility model discloses a multilayer filtering structure for alloy melt, which comprises a container for accommodating the alloy melt, an opening at the upper end of the container and a material spraying nozzle at the lower end of the container, and further comprises a filtering structure, the filtering structure comprises a cylinder body with openings at two ends, and the cylinder body is detachably connected with the upper end of the container. A plurality of layers of filter screens made of foamed ceramic are arranged in the cylinder body and are distributed at intervals along the axial direction of the cylinder body, and the diameters of meshes of the filter screens are gradually reduced from top to bottom. According to the utility model, multi-layer filtration is adopted, so that oxides or impurities in alloy melt can be effectively filtered out, the filtering effect is better, and the material spraying nozzle is not easy to block.
