Description

Technical Field

[0001] This utility model relates to the field of alloy steel smelting technology, and in particular to an alloy steel casting impurity removal smelting device. Background Technology

[0002] Alloy steel used in the cast state, also known as cast alloy steel, is classified into cast alloy structural steel and special-purpose alloy cast steel according to its application. The former consists of low and medium alloy cast steel, mainly used to manufacture general mechanical structural parts. The latter is mostly high alloy cast steel, such as wear-resistant cast steel, stainless and acid-resistant cast steel, heat-resistant cast steel, and cast alloy tool steel.

[0003] The existing alloy steel casting impurity removal smelting device uses a rotating crushing roller to perform preliminary crushing of the alloy steel raw material. The crushed alloy steel material then enters the smelting furnace for high-temperature smelting. After smelting, the alloy steel solution is filtered using a filter screen to remove impurities from the solution.

[0004] However, as an important source of recycled metal materials, scrap metal parts have a complex composition and may contain non-metallic substances. When these scrap metal parts containing non-metallic substances are directly put into the melting furnace with alloy steel without effective pretreatment, the non-metallic substances may exist in the alloy steel solution as molten impurities. The filter plate is difficult to filter out the liquid impurities, which not only affects the purity and quality of the alloy steel, but may also have an adverse effect on the subsequent processing technology and product quality. Therefore, this utility model provides an alloy steel casting impurity removal melting device. Utility Model Content

[0005] This addresses the technical problem of existing alloy steel casting impurity removal smelting devices, where non-metallic substances may be present during smelting, and these non-metallic substances may exist in the alloy steel solution in the form of molten impurities, making it difficult for filter plates to filter out liquid impurities.

[0006] The technical solution of this utility model is as follows: an alloy steel casting impurity removal and smelting device, including a smelting furnace; it also includes a first motor and a toggle assembly; a support frame is provided on one side of the smelting furnace, a crushing box is provided on the upper end of the support frame, a baffle to prevent metal from falling is provided on the upper end of the support frame, a toggle assembly is provided on one side of the baffle, a first motor is provided on one side of the crushing box, a first crushing roller is provided at the output end of the first motor, a first gear is provided on the outer side of the first crushing roller, a second gear is provided on one side of the first gear, the first gear meshes with the second gear, a second crushing roller is provided on the inner side of the second gear, and the second crushing...

[0007] Preferably, the crushing box has a slot, and the second crushing roller is rotatably connected to the inside of the crushing box through the slot.

[0008] Preferably, the support frame has a second groove, and the transmission roller is rotatably connected to the inside of the support frame through the second groove.

[0009] Preferably, the support frame has a groove three, and the magnetic roller is rotatably connected to the inside of the support frame through the groove three.

[0013] The beneficial effects of this utility model are as follows: Compared with traditional alloy steel casting impurity removal and smelting devices, where non-metallic substances may exist in the alloy steel solution during smelting, and these non-metallic substances may exist in the form of molten impurities, making it difficult for filter plates to filter liquid impurities, this device addresses this issue by having the crushed metal fall onto a conveyor belt. The conveyor belt carries the crushed metal, and when it reaches the magnetic roller, the magnetic roller attracts and moves the metal. Non-metallic substances, unaffected by the magnetic roller, fall into the non-metallic collection box. When the metal leaves the range of the magnetic roller, it falls into the metal guide box and enters the conveying cylinder. The second motor is then activated, driving the spiral blades to rotate. The spiral blades carry the metal upward to the discharge pipe, where it enters the smelting furnace for smelting. This improves the purity and quality of the alloy steel, providing high-quality raw materials for subsequent casting, forging, and other processing steps. Attached Figure Description

The slot 3 on the support frame 2 also serves as a limiting mechanism when the magnetic roller 511 rotates within the slot 3. By starting the first motor 501, the first motor 501 drives the first crushing roller 502 to rotate. The first crushing roller 502 drives the first gear 503 to rotate, the first gear 503 drives the second gear 504 to rotate, and the second gear 504 drives the second crushing roller 505 to rotate, causing the first crushing roller 502 and the second crushing roller 505 to rotate inward simultaneously.

When the metal leaves the range of the magnetic roller 511, it falls into the metal guide box 513 and enters the conveyor cylinder 514. The second motor 515 is then activated, driving the spiral blades 516 to rotate. The spiral blades 516 lift the metal upwards to the discharge pipe 517, through which it enters the smelting furnace 1 for melting.

The first crushing roller 502 drives the first gear 503 to rotate, the first gear 503 drives the second gear 504 to rotate, and the second gear 504 drives the second crushing roller 505 to rotate. This causes both the first and second crushing rollers 502 and 505 to rotate inwards simultaneously. The second crushing roller 505 drives the first pulley 506 to rotate, which in turn drives the transmission belt 507 to rotate. The transmission belt 507 drives the second pulley 508 to rotate, which in turn drives the transmission roller 509 to rotate. The transmission roller 509 drives the conveyor belt 510 to rotate, and the conveyor belt 510 drives the magnetic roller 511 to rotate. Then, the scrap metal parts are placed into the crushing box 3 and crushed by the first and second crushing rollers 502 and 505.

When it moves to the magnetic roller 511, the magnetic roller 511 attracts the metal. As the magnetic roller 511 moves, the non-metallic material, unaffected by the magnetic roller 511, falls into the non-metallic collection box 512. When the metal leaves the range of the magnetic roller 511, it falls into the metal guide box 513 and enters the conveying cylinder 514. The second motor 515 is then started, which drives the spiral blades 516 to rotate. The spiral blades 516 lift the metal up to the discharge pipe 517, and then it enters the smelting furnace 1 through the discharge pipe 517 for smelting.

[0025] Through the above steps, by starting the first motor 501, the first motor 501 drives the first crushing roller 502 to rotate, the first crushing roller 502 drives the first gear 503 to rotate, the first gear 503 drives the second gear 504 to rotate, and the second gear 504 drives the second crushing roller 505 to rotate, causing the first crushing roller 502 and the second crushing roller 505 to rotate inward simultaneously.

Then, the scrap metal parts are put into the crusher. Inside the crushing box 3, the metal is crushed by the first crushing roller 502 and the second crushing roller 505. The crushed metal falls onto the conveyor belt 510, which moves the crushed metal. When the metal reaches the magnetic roller 511, the magnetic roller 511 attracts the metal and moves it. The non-metals, not affected by the magnetic roller 511, fall into the non-metal collection box 512. When the metal leaves the range of the magnetic roller 511, it falls into the metal guide box 513 and enters the conveying cylinder 514. The second motor 515 is started, which drives the spiral blade 516 to rotate. The spiral blade 516 lifts the metal up to the discharge pipe 517 and enters the smelting furnace 1 for smelting.
