Description

Technical Field

[0001] The utility model relates to a molten steel filtering cup. Background Art

[0002] Prior art, such as Chinese invention patent document, with announcement number CN104959541B, discloses a pouring cup device and pouring method for iron mold sand-coated casting, which is applied to molten iron pouring in casting production, and belongs to the field of iron mold sand-coated casting equipment tooling. The pouring cup device in the present invention comprises an upper iron mold of the pouring cup, a resin sand mold of the pouring cup and a pouring ceramic filter screen, the upper iron mold of the pouring cup is a trumpet-shaped, the resin sand mold of the pouring cup and the upper iron mold of the pouring cup cooperate with each other, the upper iron mold of the pouring cup is located above the resin sand mold of the pouring cup, and the upper iron mold of the pouring cup has a pouring ceramic filter screen.

[0003] Based on the above, in the prior art, a pouring ceramic filter is provided in the upper iron mold of the pouring cup. The filter plays a role in filtering the molten steel when the molten steel is poured. However, the arrangement of directly arranging the filter at the bottom of the pouring cup has the problem that the molten steel directly washes the filter, which easily causes the filter to crack and be damaged. In severe cases, the filter will break and rush into the casting, causing the casting to be scrapped. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a molten steel filter cup which adopts double cup buffering to avoid the direct rush of molten steel.

[0005] A molten steel filter cup designed for this purpose includes a buffer cup, a pouring cup and a filter plate. A connecting flow channel is arranged between the buffer cup and the pouring cup. The buffer cup, the connecting flow channel and the pouring cup are connected in sequence. The filter plate is arranged in the pouring cup below the output end of the connecting flow channel.

[0006] Preferably, the connecting flow channel and the axis of the buffer cup are arranged perpendicular to each other.

[0007] Preferably, the pouring cup is opened at the upper end.

[0008] Compared with the prior art, the utility model includes a buffer cup, a pouring cup and a filter plate. A connecting flow channel is provided between the buffer cup and the pouring cup. The buffer cup, the connecting flow channel and the pouring cup are connected in sequence, and the filter plate is provided in the pouring cup below the output end of the connecting flow channel. The utility model increases the setting of the buffer cup, so that the molten steel can be input from the buffer cup, and then transported to the pouring cup through the connecting flow channel, filtered by the filter plate in the pouring cup, and then transported to the molten steel cup inlet of the mold shell. The double cup setting can buffer the molten steel, avoid the problem that the molten steel directly washes the filter plate and causes damage to the filter plate, thereby avoiding inclusion defects in the casting due to damage to the filter plate, and can optimize the defective product rate to meet production requirements.

[0012] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0013] See also Figure 1-Figure 3 A molten steel filter cup includes a buffer cup 10, a pouring cup 30 and a filter plate 40. A connecting flow channel 20 is provided between the buffer cup 10 and the pouring cup 30. The buffer cup 10, the connecting flow channel 20 and the pouring cup 30 are connected in sequence. The filter plate 40 is provided in the pouring cup 30 below the output end of the connecting flow channel 20. The utility model increases the setting of the buffer cup, so that the molten steel can be input from the buffer cup, and then transported to the pouring cup through the connecting flow channel, and then filtered by the filter plate in the pouring cup before being transported to the molten steel cup inlet of the mold shell. The double cup setting can buffer the molten steel, avoid the problem that the molten steel directly washes the filter plate and causes damage to the filter plate, thereby avoiding inclusion defects in the casting due to damage to the filter plate, and can optimize the defective rate to meet production requirements.

[0014] See also Figure 1 The connecting flow channel 20 is perpendicular to the axis of the buffer cup 10. The connecting flow channel 20 arranged perpendicular to each other can further slow down the flow of molten steel and avoid damage caused by local point impact of fast-flowing molten steel on the filter plate.

[0015] See also Figures 1 to 3 The pouring cup 30 has an opening at the upper end, and the purpose of the opening is to facilitate the installation of the filter plate 40.

[0016] See also Figure 3 A card slot 310 is provided on the inner wall of the pouring cup 30. When installing, the filter screen 40 is embedded into the pouring cup 30 from top to bottom, and the card slot 310 can limit the filter screen 40 from moving downward.
