Description

Technical Field

[0001] The embodiments of this utility model relate to the field of crude nickel-iron refining technology, specifically, to a medium-frequency melting furnace for crude nickel-iron refining. Background Technology

[0002] Refining crude ferronickel is an important smelting process aimed at removing impurities from crude ferronickel and increasing its nickel content and metal purity. Crude ferronickel typically contains high levels of sulfur, phosphorus, carbon, and other impurities, which need to be effectively removed during the refining process to produce high-purity ferronickel that meets the requirements and is widely used in the manufacture of stainless steel and alloy materials.

[0003] In the existing technology, medium-frequency melting furnaces require manual continuous feeding before processing, and it is difficult to solve the problem of automatic feeding, which increases manual labor and reduces work efficiency. Therefore, we propose a medium-frequency melting furnace for crude nickel-iron refining. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a medium-frequency melting furnace for refining crude nickel-iron, which solves the problem of not being able to automatically feed crude nickel-iron in related technologies.

[0005] According to one aspect, at least one embodiment of the present invention provides a medium-frequency melting furnace for refining crude nickel-iron, including a wall, a bottom plate fixedly connected to the side of the wall, a medium-frequency melting furnace disposed on the top of the bottom plate, a feeding area disposed on the side of the bottom plate, and a feeding mechanism disposed on the top of the bottom plate.

[0006] The feeding mechanism includes a support column, the bottom of which is fixedly connected to the top of a base plate. A mounting plate is fixedly connected to the side of the support column, and a motor is fixedly connected to the side of the mounting plate. A rotating shaft is fixedly connected to the output end of the motor, and a gear is fixedly threaded through the circumference of the rotating shaft. A sliding groove is provided on the side of the mounting plate, and a rack is slidably connected inside the sliding groove. A push rod is fixedly connected to the top of the rack. A storage box is fixedly connected to the top of the support column, and a support shaft is rotatably connected to the side of the storage box. A conveying channel is fixedly connected to the circumference of the support shaft.

[0007] For example, in at least one embodiment of the present invention, a medium-frequency melting furnace for refining crude nickel-iron is provided, which further includes: a movable groove is provided on the side of the storage box, and a baffle plate is slidably connected inside the movable groove. The end of the baffle plate away from the storage box is set as an inclined surface, the purpose of which is to ensure that the outlet of the storage box is closed when not in use.

[0008] A return spring is fixedly connected to the side of the support column. The end of the return spring away from the side of the support column is fixedly connected to the side of the conveying channel. The purpose of this is to ensure that the conveying channel can automatically reset.

[0009] The number of the support column and the reset spring is two, and they are symmetrical to each other along the vertical central axis of the base plate. The weight of the baffle plate is higher than the frictional force between the baffle plate and the storage box. The purpose is to ensure that the baffle plate can descend by its own weight when it is under force.

[0010] The bottom of the conveying channel is located on the displacement trajectory of the push rod, and the side of the baffle is located on the displacement trajectory of the conveying channel. The purpose is to ensure that the movement of the push rod can push the conveying channel, and to ensure that the rotation of the conveying channel can push the baffle.

[0011] According to another aspect, at least one embodiment of the present invention also provides a medium-frequency melting furnace for refining crude nickel-iron, including a turning mechanism. The turning mechanism includes a threaded rod, one end of which is fixedly connected to the end of a rotating shaft away from the motor output end. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A support frame one is fixedly connected to the top of the threaded sleeve. A connecting plate is hinged inside the support frame one. A support frame two is fixedly connected to the side of the medium-frequency melting furnace. The interior of the support frame two is hinged to one end of the connecting plate. A control shaft is rotatably connected to the side of the medium-frequency melting furnace. The circumferential surface of the control shaft is fixedly connected to the top of the feeding area.

[0012] For example, in at least one embodiment of the present invention, a medium-frequency melting furnace for refining crude nickel-iron is provided, which further includes: a connecting rod fixedly connected to the side of the threaded sleeve, a telescopic rod rotatably connected to the top of the connecting rod, and a baffle fixedly connected to the telescopic end of the telescopic rod. The purpose of this is to prevent the internal materials from being transported out of the prescribed route when the medium-frequency melting furnace is tilted at too large an angle, which could lead to leakage and cause danger.

[0013] A limiting plate is fixedly connected to the top of the base plate, and the side of the limiting plate penetrates the circumferential surface of the threaded rod. A limiting rod is fixedly connected to the top of the medium-frequency melting furnace, the purpose of which is to limit the displacement distance of the threaded sleeve.

[0014] The limiting plate has a limiting shaft fixedly connected to its side. The circumferential surface of the limiting shaft passes through and slides through the side of the threaded sleeve. The purpose of this is to prevent the threaded sleeve from rotating during movement.

[0015] The limiting plates are provided in two quantities and are arranged linearly along the side of the threaded sleeve. The bottom of the baffle is in contact with the inlet of the medium-frequency melting furnace, the purpose of which is to ensure that the baffle blocking part does not leak.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] 1. In this utility model, through the cooperation between components such as the motor, storage bin, and conveying channel of the feeding mechanism, when using the medium-frequency melting furnace, the operator starts the motor to rotate forward, driving the rotating shaft and gear to rotate. The gear drives the rack to move in the slide groove, pushing the push rod and the bottom of the conveying channel. The conveying channel rotates through the support shaft, pressing the baffle plate from the side, causing it to move upward, opening the outlet of the storage bin, and conveying the material to the medium-frequency melting furnace. When the material reaches the outlet and is refined, the operator starts the motor to rotate in reverse, driving the rack to reset. The conveying channel is reset by the reset spring, and the baffle plate slides down under gravity, closing the outlet of the storage bin. This design achieves the effect of automatic material conveying, ensuring the smooth progress of the melting process, avoiding material leakage, and improving the automation and stability of the equipment.

[0018] 2. In this utility model, through the cooperation between the control shaft, baffle, and limiting shaft of the flipping mechanism, when the motor reverses, the drive shaft drives the threaded rod to rotate, and the threaded sleeve moves linearly. Through the support frame, it pushes the connecting plate, thereby driving the medium-frequency melting furnace to rotate and smoothly discharge the material. The threaded sleeve synchronously drives the connecting rod to move, which in turn drives the telescopic rod and the baffle to partially block the inlet of the medium-frequency melting furnace to prevent excessive tilting and ensure that the material flows along the prescribed route. This design achieves the effect of automatically flipping the medium-frequency melting furnace, improving the stability and efficiency of material discharge after melting.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0028] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-6 As shown, it illustrates a medium-frequency melting furnace for refining crude nickel-iron in one embodiment of the present invention, including a wall 1, a bottom plate 2 fixedly connected to the side of the wall 1, a medium-frequency melting furnace 3 provided on the top of the bottom plate 2, a feeding area 4 provided on the side of the bottom plate 2, and a feeding mechanism 5 provided on the top of the bottom plate 2.

[0034] The feeding mechanism 5 includes a support column 51, the bottom of which is fixedly connected to the top of the base plate 2. A mounting plate 52 is fixedly connected to the side of the support column 51. A motor 53 is fixedly connected to the side of the mounting plate 52. A rotating shaft 54 ​​is fixedly connected to the output end of the motor 53. A gear 55 is fixedly passed through the circumference of the rotating shaft 54. A sliding groove 56 is provided on the side of the mounting plate 52. A rack 57 is slidably connected inside the sliding groove 56. A push rod 58 is fixedly connected to the top of the rack 57. A storage box 59 is fixedly connected to the top of the support column 51. A support shaft 510 is rotatably connected to the side of the storage box 59. A conveying channel 511 is fixedly connected to the circumference of the support shaft 510.

[0035] In some examples, the material storage bin 59 is provided with a moving groove 512 on its side, and a baffle plate 513 is slidably connected inside the moving groove 512. The end of the baffle plate 513 away from the material storage bin 59 is set as an inclined surface, the purpose of which is to ensure that the outlet of the material storage bin 59 is closed when it is not in use.

[0036] A return spring 514 is fixedly connected to the side of the support column 51. The end of the return spring 514 away from the side of the support column 51 is fixedly connected to the side of the conveying channel 511. The purpose is to ensure that the conveying channel 511 can automatically reset.

[0037] There are two support columns 51 and reset springs 514, which are symmetrical to each other along the vertical central axis of the base plate 2. The weight of the baffle plate 513 is higher than the frictional force between the baffle plate 513 and the storage box 59. The purpose is to ensure that the baffle plate 513 can descend by its own weight when it is under force.

[0038] The bottom of the conveying channel 511 is located on the displacement trajectory of the push rod 58, and the side of the baffle plate 513 is located on the displacement trajectory of the conveying channel 511. The purpose is to ensure that the movement of the push rod 58 can push the conveying channel 511, and to ensure that the rotation of the conveying channel 511 can push the baffle plate 513.

[0039] For example, such as Figures 1-6 As shown, when the medium-frequency melting furnace 3 needs to be used, the operator starts the motor 53 to rotate forward, causing the output end of the motor 53 to rotate in the forward direction. The rotation of the output end of the motor 53 drives the rotating shaft 54 ​​to rotate, and the rotation of the rotating shaft 54 ​​drives the gear 55 to rotate. Through the meshing of the gear 55 and the rack 57, the rotation of the gear 55 causes the rack 57 to move inside the slide groove 56. The movement of the rack 57 causes the push rod 58 to move. During the movement of the push rod 58, it pushes the bottom of the conveying channel 511. The bottom of the conveying channel 511 is subjected to force and rotates through the support shaft 510. The rotation of the support shaft 510 causes the side of the conveying channel 511 to be blocked. The inclined surface of the material plate 513 is pressed, causing the baffle plate 513 to move upward inside the moving trough 512 under force. At this time, the side of the conveying channel 511 overlaps with the outlet of the storage box 59, causing the material inside the storage box 59 to slide down into the medium frequency melting furnace 3 through the conveying channel 511. When the conveyed material reaches the required quantity and is refined, the operator starts the motor 53 to reverse, causing the gear 55 to rotate and drive the rack 57 to reset. This causes the conveying channel 511 to reset through the reset spring 514. At this time, the baffle plate 513 is not under force and slides down to the bottom of the moving trough 512 by its own gravity, closing the outlet of the storage box 59.

[0040] like Figures 1-6As shown, this invention illustrates a medium-frequency induction furnace for refining crude nickel-iron, which is largely the same as the above-described technical solution. Therefore, only the differences are described. The furnace includes a flipping mechanism 6, which comprises a threaded rod 61. One end of the threaded rod 61 is fixedly connected to the end of the rotating shaft 54 ​​away from the output end of the motor 53. A threaded sleeve 62 is threadedly connected to the circumferential surface of the threaded rod 61. A support frame 63 is fixedly connected to the top of the threaded sleeve 62. A connecting plate 64 is hinged inside the support frame 63. A second support frame 65 is fixedly connected to the side of the medium-frequency induction furnace 3. The interior of the second support frame 65 is hinged to one end of the connecting plate 64. A control shaft 66 is rotatably connected to the side of the medium-frequency induction furnace 3. The circumferential surface of the control shaft 66 is fixedly connected to the top of the feeding area 4.

[0041] In some examples, the following are also included: a connecting rod 67 is fixedly connected to the side of the threaded sleeve 62, a telescopic rod 68 is rotatably connected to the top of the connecting rod 67, and a baffle 69 is fixedly connected to the telescopic end of the telescopic rod 68. The purpose of this is to prevent the internal materials from being transported out of the prescribed route when the induction furnace 3 is tilted at too large an angle, which could lead to leakage and cause danger.

[0042] A limiting plate 610 is fixedly connected to the top of the base plate 2. The side of the limiting plate 610 penetrates the circumferential surface of the threaded rod 61. A limiting rod 611 is fixedly connected to the top of the medium frequency melting furnace 3. Its purpose is to limit the displacement distance of the threaded sleeve 62.

[0043] The side of the limiting plate 610 is fixedly connected to a limiting shaft 612. The circumferential surface of the limiting shaft 612 is slidably connected to the side of the threaded sleeve 62. The purpose of this is to prevent the threaded sleeve 62 from rotating during movement.

[0044] Two limit plates 610 are provided and are arranged in a linear array along the side of the threaded sleeve 62. The bottom of the baffle 69 is in contact with the inlet of the medium frequency melting furnace 3. The purpose is to ensure that the baffle 69 does not leak.

[0045] For example, such as Figures 1-6As shown, when motor 53 reverses, it drives shaft 54 ​​to rotate. Shaft 54 ​​drives threaded rod 61 to rotate. The rotation of threaded rod 61 causes threaded sleeve 62 to move linearly through limiting shaft 612. The linear movement of threaded sleeve 62 further drives support frame 1 63, pushing connecting plate 64 to move along a predetermined path. The movement of connecting plate 64 causes medium-frequency melting furnace 3 to generate a corresponding pushing effect through support frame 2 65. In turn, it drives medium-frequency melting furnace 3 to rotate through control shaft 66, thereby smoothly conveying the molten material to the internal container of the unloading area 4 for unloading. During this process, the movement of threaded sleeve 62 also drives connecting rod 67 to move forward. The movement of connecting rod 67 drives telescopic rod 68 to move accordingly. The movement of telescopic rod 68 drives baffle 69 to move, thereby partially blocking the inlet of medium-frequency melting furnace 3, preventing medium-frequency melting furnace 3 from having an excessive tilt angle, ensuring that the material flows along the prescribed route, and avoiding abnormal flow of molten material due to excessive furnace tilt.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
