Description

Technical Field

[0001] The utility model discloses a casting pot with a built-in filter screen, belonging to the field of casting equipment, and relates to a casting pot with a built-in filter screen with a large area. Background Art

[0002] A casting pot is a pot used for casting molten metal. Currently, casting pots are roughly divided into two categories: one is the anti-oxidation casting pot, and the other is the wide-mouthed casting pot. The anti-oxidation casting pot is mainly used for casting aluminum alloy solution. Its advantages are that the casting pot has a small inlet, the metal solution inside has less contact with the air, and the metal solution is not easily oxidized. Its disadvantages are that the casting pot has a complex structure, oxides adhere to the inner wall and are difficult to clean, it cannot filter residues and oxides, the casting speed is slow, and the casting is prone to pores. The wide-mouthed casting pot is mainly used for casting steel solution. Its advantages are that it is easy to feed and discharge. Its disadvantages are that it cannot filter residues and oxides, the casting speed is slow, and the casting is prone to pores.

[0003] Application number: ZL2022216149961 An antioxidant and heat-insulating casting pot belongs to the field of mechanical manufacturing. An inlet and outlet are provided in front of the casting pot body, and a hopper is installed in front of the inlet and outlet. An exhaust hole is provided on the rear of the top of the casting pot body. Terminals are installed on the front and back of the casting pot body respectively, and the two terminal posts are respectively connected to two graphite electrodes installed on the inner wall of the casting pot body. A support shaft is installed on the left side of the casting pot body and a connecting shaft is installed on the right side. The hanging arm is provided above the casting pot body, the hanging ring on the left side of the hanging arm is movably connected to the support shaft, the hanging ring on the right side of the hanging arm is movably connected to the connecting shaft, and a hook is installed on the top of the hanging arm. The above effectively prevents the internal metal solution from contacting with the air for a long time and reduces the degree of oxidation on the surface of the metal solution. Then, the graphite electrode is used to continuously provide current to the metal solution to make it self-heating and have the effect of slowing down the cooling.

[0004] Application number: ZL2022233186069 A splash-proof and positionable casting pot belongs to the field of casting equipment. The casting pot is equipped with a U-shaped boom through the boom shaft on the left and right sides, an electric pulley is installed on the back above the boom, and the electric pulley is connected to the bottom of the back of the casting pot through a wire rope. A conical first-level funnel is installed between two D-shaped brackets installed on both sides of the V-shaped liquid outlet on the front upper part of the casting pot. The first-level funnel is connected to the two brackets through the supporting shafts on both sides. A conical second-level funnel is installed at the front and back below the first-level funnel through the supporting shafts. A conical third-level funnel is installed at the left and right below the second-level funnel through the supporting shafts. A conical fourth-level funnel is installed at the front and back below the third-level funnel through the supporting shafts. The molten metal flows into the first-level funnel, the second-level funnel, the third-level funnel, and the fourth-level funnel through the liquid outlet. The outlet below the fourth-level funnel is aligned with the pouring gate and then flows into the pouring gate and the mold box.

[0005] The above-mentioned antioxidant and heat-insulating casting pot uses an inlet and outlet, a hopper, an exhaust hole, a terminal, a graphite electrode, a support shaft, a connecting shaft, a boom, and a hook to prevent the internal molten metal from coming into contact with the air for a long time and reduce the degree of oxidation on the surface of the molten metal. The above-mentioned anti-splash and positionable casting pot uses a casting pot, a boom shaft, a boom, an electric pulley, a wire rope, a liquid outlet, a bracket, a first-level funnel, a support shaft, a second-level funnel, a third-level funnel, and a fourth-level funnel to align the liquid outlet with the pouring port and then flow into the pouring port and the mold box. Both of the above-mentioned two types of casting pots cannot achieve the effect of filtering residues and oxides. Therefore, there is a need for a casting pot with a fast feeding speed, a fast discharging speed, and the ability to quickly filter residues and oxides during the discharging process.
