Description

Technical Field

[0001] This utility model specifically relates to the field of smelting furnace technology, and more specifically to an aluminum rod smelting furnace. Background Technology

[0002] An aluminum rod melting furnace is an industrial heating device used to heat solid aluminum ingots, aluminum scrap, and other raw materials to a molten state, and then refine and remove impurities to prepare qualified molten aluminum, which is ultimately used for casting aluminum rods. It is a core upstream equipment in the aluminum processing industry (such as profile extrusion and aluminum alloy forging). Its core function is to achieve integrated processing of aluminum raw materials through "melting-purification-heat holding," ensuring that the output molten aluminum has a uniform composition and low impurity content, meeting the process requirements for subsequent aluminum rod casting.

[0003] Traditional smelting furnaces can only perform simple smelting functions and cannot directly cast molten aluminum into rods. The molten aluminum needs to be transported out for casting, which lowers the temperature of the molten aluminum and has a high risk factor. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum rod smelting furnace that can directly discharge the molten aluminum and then pour it into an aluminum casting cylinder to form a new aluminum rod. This reduces the intermediate handling of the molten aluminum, thereby reducing labor intensity and enabling rapid casting of aluminum rods; thus solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An aluminum rod smelting furnace includes a frame body, a top plate fixedly installed on the top of the frame body, and a smelting furnace installed on the top of the top plate; the bottom of the smelting furnace has an aluminum outlet pipe, and the aluminum outlet pipe extends to the top of the tilting furnace.

[0007] The rotating furnace has convex shafts at both ends on the side near the casting rod assembly, which are installed with a bracket through bearings, and the bracket is fixed on the machine frame. The lower part of the rotating furnace away from the casting rod assembly is movably connected to the rotating cylinder through a fisheye joint. The bottom of the rotating cylinder is connected to a fixed seat through a rotating shaft, and the fixed seat is fixed on the machine frame.

[0008] As a further technical solution of this utility model, the rotary oven includes a furnace body, and multiple through holes are circumferentially opened at both ends of the furnace body along the arc-shaped furnace cavity, and thermocouple heaters are embedded inside the through holes.

[0009] A horizontal plate is fixed to one side of the top of the furnace body, and a thermocouple temperature sensor is fixed above the horizontal plate. The lower end of the thermocouple temperature sensor extends into the furnace cavity of the furnace body.

[0010] As a further technical solution of this utility model, the upper surface of the furnace body near the casting rod assembly is provided with multiple aluminum outlets, which are connected to a through groove located inside the furnace body.

[0011] As a further technical solution of this utility model, the casting rod assembly includes a flipping frame, on which multiple cast aluminum cylinders are fixedly installed; the two ends of the flipping frame are provided with fixed shafts, which are installed with bearing brackets through bearings; the bottom of the bearing bracket is fixed with a slide block, which is slidably connected to the slide rail; one end of the flipping frame is also fitted with a rotary cylinder, which is fixedly connected to the bearing bracket.

[0012] The outer side of the slide block is fixedly connected to the cylinder rod of the telescopic cylinder; the telescopic cylinder is fixed to the outer side of the frame.

[0013] As a further technical solution of this utility model, a cooling shell is fitted onto the outside of each cast aluminum cylinder. The upper end of the cooling shell is welded to the tilting frame. A water inlet pipe is connected to the outside of the cooling shell through a tee joint or elbow. A water outlet pipe is connected to the bottom of the cooling shell through a tee joint or elbow. The water inlet pipe and the water outlet pipe are connected to the water chiller.

[0014] As a further technical solution of this utility model, a guide plate is provided on the inner side of the frame body near the casting rod assembly; a controller is also fixed on the top plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In use, waste aluminum rods are placed in a smelting furnace for melting and casting. After the aluminum liquid is refined, it is discharged into a tilting furnace through a copper aluminum liquid pipe at the bottom. Then the tilting furnace is tilted so that the aluminum liquid is poured into the casting rod assembly, thereby realizing the recasting of aluminum rods. This reduces the intermediate transfer of aluminum liquid, which can reduce labor intensity and quickly realize the casting of aluminum rods.

[0017] 2. In this utility model, after the refined aluminum liquid is transported into the furnace, the thermocouple heater also heats the furnace to keep the aluminum liquid warm and prevent it from solidifying too quickly and making subsequent casting impossible; the thermocouple temperature sensor monitors the temperature of the aluminum liquid in the furnace to ensure the temperature of the aluminum liquid is stable.

[0018] 3. In this utility model, when casting aluminum rods, the cylinder rod of the tilting cylinder extends, causing the entire tilting furnace to tilt around the movable connection between the tilting furnace and the support as the axis. The molten aluminum inside the furnace enters the aluminum outlet through the channel, and then is discharged from the aluminum outlet into the aluminum casting cylinder, thereby realizing the casting of aluminum rods.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-8In this embodiment of the present invention, an aluminum rod smelting furnace includes a frame body 1, a top plate 7 fixedly installed on the top of the frame body 1, and a smelting furnace 8 installed on the top of the top plate 7; the bottom of the smelting furnace 8 has an aluminum outlet pipe, and the aluminum outlet pipe extends to the top of the tilting furnace 2.

[0032] The rotating furnace 2 has convex shafts at both ends on the side near the casting rod assembly 5, and is installed with the bracket 4 through bearings, so the bracket 4 is fixed on the frame body 1; the lower part of the rotating furnace 2 away from the casting rod assembly 5 is movably connected to the rotating cylinder 3 through a fisheye joint; the bottom of the rotating cylinder 3 is connected to a fixed seat through a rotating shaft, so the fixed seat is fixed on the frame body 1.

[0033] By adopting the above technical solution, the waste aluminum rods are placed into the smelting furnace 8 for melting and casting. After the aluminum liquid is refined, it is discharged into the tilting furnace 2 through the copper aluminum liquid pipe at the bottom. Then the tilting furnace 2 is tilted so that the aluminum liquid is poured into the casting rod assembly 5, thereby realizing the recasting of the aluminum rods. This reduces the intermediate transfer of aluminum liquid, which can reduce labor intensity and quickly realize the casting of aluminum rods.

[0034] It should be noted that the smelting furnace 8 is an induction smelting furnace, which uses the principle of electromagnetic induction. Alternating current passes through the coil to generate a magnetic field, causing the aluminum material to heat up and melt.

[0035] When smelting scrap aluminum rods, the smelting furnace 8 adds refining agents (such as hexachloroethane and nitrogen) to the molten aluminum. Hydrogen in the molten aluminum is removed through chemical degassing and physical slag removal, which can effectively prevent porosity and oxide slag from appearing in newly cast aluminum rods and prevent the mechanical properties of aluminum rods from declining.

[0036] It should be noted that when directly heating an induction melting furnace, the heating rate should be controlled at 50-80℃ / hour to avoid localized overheating of the molten aluminum due to excessively rapid heating.

[0037] In addition, the refining temperature should be controlled at 720-740℃ and the refining time should be 20-30 minutes. During this time, the aluminum liquid needs to be stirred (stirring speed 30-50 rpm) to ensure that the refining agent and the aluminum liquid are in full contact (exceeding 800℃ will result in an increase in aluminum oxide slag).

[0038] The smelting furnace 8 is equipped with conventional components such as manholes, material inlets, stirring mechanisms, exhaust vents, and thermocouple sensors. The smelting furnace uses existing technology, and its specific structure will not be described in detail here.

[0039] In this embodiment, the rotating furnace 2 includes a furnace body 21, and multiple through holes 22 are circumferentially opened at both ends of the furnace body 21 along the arc-shaped furnace cavity. A thermocouple heater 10 is embedded inside the through holes 22.

[0040] A horizontal plate 25 is fixed on one side of the top of the furnace body 21, and a thermocouple temperature sensor 26 is fixed above the horizontal plate 25. The lower end of the thermocouple temperature sensor 26 extends into the furnace cavity of the furnace body 21.

[0041] By adopting the above technical solution, after the refined aluminum liquid is transported into the furnace body 21, the thermocouple heater 10 also heats the furnace body 21 to keep the aluminum liquid warm and prevent the aluminum liquid from solidifying too quickly and making subsequent casting impossible; the thermocouple temperature sensor 26 monitors the temperature of the aluminum liquid in the furnace body 21 to ensure the temperature of the aluminum liquid is stable.

[0042] More specifically, the upper surface of the furnace body 21 near the casting rod assembly 5 is provided with multiple aluminum outlets 23, which are connected to a through groove 24 located inside the furnace body 21.

[0043] By adopting the above technical solution, when casting aluminum rods, the cylinder rod of the tilting cylinder 3 extends, causing the entire tilting furnace 2 to tilt around the movable connection between the tilting furnace 2 and the support 4. The molten aluminum inside the furnace body 21 enters the aluminum outlet 23 through the channel 24, and then is discharged from the aluminum outlet 23 into the aluminum casting cylinder 52, thereby realizing the casting of aluminum rods.

[0044] In this embodiment, the casting rod assembly 5 includes a flipping frame 51, on which a plurality of cast aluminum cylinders 52 are fixedly mounted; the two ends of the flipping frame 51 are provided with fixed shafts, which are installed with bearing brackets 53 through bearings; the bottom of the bearing bracket 53 is fixed with a slide block 54, which is slidably connected to the slide rail 56; a rotary cylinder 510 is also installed at one end of the flipping frame 51, which is fixedly connected to the bearing bracket 53.

[0045] The outer side of the slide block 54 is fixedly connected to the cylinder rod of the telescopic cylinder 55; the telescopic cylinder 55 is fixed to the outer side of the frame body 1.

[0046] More specifically, each cast aluminum cylinder 52 is fitted with a cooling shell 57 on its outer side. The upper end of the cooling shell 57 is welded to the tilting frame 51. A water inlet pipe 58 is connected to the outer side of the cooling shell 57 through a tee joint or elbow, and a water outlet pipe 59 is connected to the bottom of the cooling shell 57 through a tee joint or elbow. The water inlet pipe 58 and the water outlet pipe 59 are connected to a water chiller. A guide plate 6 is provided on the inner side of the frame body 1 near the casting rod assembly 5. A controller 9 is also fixed on the top plate 7.

[0047] By adopting the above technical solution, when the molten aluminum is poured into the aluminum casting cylinder 52, the aluminum rod can be formed by natural cooling; or water cooling can be used to assist cooling and accelerate the forming of the aluminum rod.

[0048] When cold water cooling molding is used, the water inlet pipe 58 delivers cooling water to the cooling shell 57 to cool the cast aluminum cylinder 52. The water that has exchanged heat with the cast aluminum cylinder 52 is discharged through the water outlet pipe 59 at the bottom and is recycled after being cooled by the water chiller.

[0049] After the aluminum rod cools and solidifies, the cylinder rod of the telescopic cylinder 55 retracts, causing the slide block 54 to slide outward along the slide rail 56. When it slides to the side of the guide plate 6, the rotary cylinder 510 is activated, causing the tilting frame 51 to tilt as a whole, so that the cast aluminum plate is tilted onto the guide plate 6. Then the aluminum rod slides down the guide plate 6 to the ground, so that workers or crane clamps can remove it.

[0050] The working principle of this utility model is as follows: When in use, waste aluminum rods are placed into the smelting furnace 8 for melting and casting. After the aluminum liquid is refined, it is discharged into the tilting furnace 2 through the copper aluminum liquid pipe at the bottom. After the refined aluminum liquid is transported into the furnace body 21, the thermocouple heater 10 also heats the furnace body 21 to keep the aluminum liquid warm and prevent the aluminum liquid from solidifying too quickly and making subsequent casting impossible. The thermocouple temperature sensor 26 monitors the temperature of the aluminum liquid in the furnace body 21 to ensure the temperature of the aluminum liquid is stable.

[0051] During the casting of aluminum rods, the cylinder rod of the tilting cylinder 3 extends, causing the entire tilting furnace 2 to tilt around the movable connection between the tilting furnace 2 and the support 4. The molten aluminum inside the furnace body 21 enters the aluminum outlet 23 through the channel 24, and then is discharged from the aluminum outlet 23 into the aluminum casting cylinder 52. When the molten aluminum is poured into the aluminum casting cylinder 52, the aluminum rod can be formed by natural cooling; alternatively, water cooling can be used to assist in cooling and accelerate the forming of the aluminum rod.

[0052] When cold water cooling molding is used, the water inlet pipe 58 delivers cooling water to the cooling shell 57 to cool the cast aluminum cylinder 52. The water that has exchanged heat with the cast aluminum cylinder 52 is discharged through the water outlet pipe 59 at the bottom and is recycled after being cooled by the water chiller.

[0053] After the aluminum rod cools and solidifies, the cylinder rod of the telescopic cylinder 55 retracts, causing the slide block 54 to slide outward along the slide rail 56. When it slides to the side of the guide plate 6, the rotary cylinder 510 is activated, causing the tilting frame 51 to tilt as a whole, so that the cast aluminum plate is tilted onto the guide plate 6. Then the aluminum rod slides down the guide plate 6 to the ground, so that workers or crane clamps can remove it.

[0054] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0055] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
