[0002] In the industrial spinning production process, mechanical impurities and agglomerated particles in the high-temperature melt are the main factors affecting the quality of spinning and spinning. Therefore, the spinning components of the existing structure generally use a weighted filtering structure to filter them to improve the quality of the spinning. However, this filtering structure is generally filter sand wrapped in a filter mesh, and its filtration is a primary filtration. Not only is the filtration of mechanical impurities and agglomerated particles insufficient, but the normal flow of the melt is also easily affected by the accumulation of impurities. Summary of the invention

[0005] Furthermore, the upper plate surface of the filter plate is evenly distributed with primary filter holes connected to the storage cavity, the inner circle of the hollow filter column is evenly distributed with secondary filter holes connected to its sandwich structure, and the outer circle of the hollow filter column is evenly distributed with tertiary filter holes connected to its sandwich structure. The aperture of the primary filter hole is larger than the aperture of the secondary filter hole, and the aperture of the secondary filter hole is larger than the aperture of the tertiary filter hole.

[0006] Furthermore, the filter material is filter sand whose particle size is larger than the pore size of the third-level filter hole.

[0007] Furthermore, the inner wall of the sand cup body has a step support body corresponding to the filter plate, and the filter plate is placed in the cup body from the cup mouth of the sand cup body and supported by the step support body.

[0008] Furthermore, the bottom of the filter plate has a mounting opening corresponding to the hollow filter column, and the hollow filter column is docked with the mounting opening, so that the hollow filter column is in a non-contact suspended state relative to the inner bottom of the sand cup body.

[0009] Furthermore, a plurality of melt discharging inclined holes are arranged through the bottom of the sand cup body.

[0010] Beneficial effect: The utility model forms a three-stage melt filtration structure through the built-in filter plate of the sand cup and the hollow filter column, thereby gradually realizing three-stage filtration of mechanical impurities and agglomerated particles from large to small, achieving more detailed filtration of the melt, fully filtering out the mechanical impurities and agglomerated particles in the melt, and avoiding excessive accumulation of filtered impurities to affect the flow of the melt, greatly improving the spinning quality and improving production efficiency.
