Description

Technical Field

[0001] This utility model relates to the field of aluminum-manganese alloy production and manufacturing technology, and more specifically, to a melting and stirring device for manufacturing aluminum-manganese alloys. Background Technology

[0002] The production and application of aluminum-manganese alloy pipes have long been widespread. However, in the smelting process of aluminum-manganese alloy pipe production, the existing smelting equipment does not stir the aluminum-manganese raw materials sufficiently during the smelting process. This results in low smelting efficiency due to uneven heating of the aluminum-manganese raw materials.

[0003] Patent authorization number CN212253719U discloses a melting and stirring device for manufacturing aluminum-manganese alloy, including a melting shell, a melting barrel sitting on the melting shell, an electromagnetic heater fixed inside the melting shell, a conical gear ring sleeved on the outer wall of the melting barrel, the conical gear ring being slidably connected to the upper side of the melting shell, a motor fixed on the upper side of the melting shell, a conical gear connected to the output shaft end of the motor, the conical gear cooperating with the conical gear ring, a stirring device inside the melting barrel, the rotation direction of the rotating shaft being opposite to the rotation direction of the melting barrel, and a barrel cover hinged to the mounting plate, which enables the aluminum-manganese raw materials to be stirred more evenly and fully during melting, accelerating their melting, thereby making the melting efficiency of aluminum-manganese alloy higher, and during the melting process, nitrogen gas is continuously injected into the melting barrel to reduce the oxygen content in the melting barrel, thereby improving the melting quality of aluminum-manganese alloy.

[0004] However, in the process of stirring molten alloy, patent authorization number CN212253719U mainly uses axial stirring, which has limited impact on the flow field disturbance of the molten alloy, thus affecting the stirring effect and resulting in an unsatisfactory alloy mixing effect. In addition, the contact parts between the ball bearings and the structural parts dry-rub, which makes the structural parts prone to wear and affects their service life. Therefore, we propose a molten stirring device for aluminum-manganese alloy manufacturing to solve the above-mentioned problems. Utility Model Content

[0020] 3. Beneficial effects

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] (1) In this scheme, the raw material is heated and melted by starting the electromagnetic heater. During the melting process, the reduction motor is started. The active bevel gear and the driven bevel gear mesh, so that the sleeve and the shaft move in opposite directions on the same axis. This allows the blades on the sleeve and the shaft to stir the molten raw material, which can effectively improve the disturbance of the raw material flow field. In addition, during the synchronous rotation of the connecting frame, the stirring paddle will rotate under the action of the flow field disturbance, thereby disturbing the radial flow field of the raw material and improving the mixing effect of the raw material.

[0023] (2) In this solution, lubricating oil is added to the inside of the protective box through the filling port, so that the lubricating oil covers the driven bevel gear and the driving bevel gear. Then, the filling port is blocked with a plug. When the driven bevel gear works with the driving bevel gear, the wear between them is reduced and the service life is extended.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Please see Figure 1-5 A melting and stirring device for manufacturing aluminum-manganese alloy includes a melting tank 1, a melting barrel 2 located on the melting tank 1, a barrel cover 3 installed on the top of the melting barrel 2, and an electromagnetic heater 4 installed inside the melting tank 1. A protective box 5 is installed on the upper surface of the barrel cover 3. A sleeve 6 is installed inside the protective box 5, penetrating the barrel cover 3 and extending to the inside of the melting barrel 2. A shaft 7 is rotatably connected to the inside of the sleeve 6. A driven bevel gear 8 is installed at the top of both the sleeve 6 and the shaft 7. A reduction motor 9 is installed on the outer wall of the protective box 5. The power output end of the reduction motor 9 is driven by a driving bevel gear 10 that meshes with the driven bevel gear 8.

[0034] Blades 11 and connecting frames 12 are installed on the outer walls of both sleeve 6 and shaft 7, and both ends of the connecting frame 12 are rotatably connected to stirring paddles 13.

[0035] It should be noted that when using this aluminum-manganese alloy manufacturing melting and stirring device, the aluminum-manganese raw material is placed into the melting tank 2, and the electromagnetic heater 4 is started to heat the raw material to melt it. During the melting process, the reduction motor 9 is started, and the active bevel gear 10 meshes with the driven bevel gear 8, so that the sleeve 6 and the shaft 7 move in opposite directions on the same axis. This causes the blades 11 on the sleeve 6 and the shaft 7 to stir the molten raw material, which can effectively improve the disturbance of the raw material flow field. In addition, during the synchronous rotation of the connecting frame 12, the stirring paddle 13 will rotate under the action of the flow field disturbance, thereby disturbing the radial flow field of the raw material and improving the mixing effect of the raw material.

[0036] like Figure 1 , Figure 5 As shown, the inner side of the protective box 5 is filled with lubricating oil that does not cover the driven bevel gear 8 and the driving bevel gear 10. The top of the protective box 5 is provided with a filling port, and the inner side of the filling port is detachably connected with a plug 14. The outer wall root of the protective box 5 is connected to a discharge pipe 15, and a shut-off valve is installed on the discharge pipe 15.

[0037] It should be noted that by adding lubricating oil to the inside of the protective box 5 through the filling port, the lubricating oil covers the driven bevel gear 8 and the driving bevel gear 10. Then, the filling port is blocked with the plug 14. When the driven bevel gear 8 and the driving bevel gear 10 work together, the wear between them is reduced and the service life is extended. The lubricating oil is discharged through the discharge pipe 15 by opening the shut-off valve, and the lubricating oil is replaced regularly.

[0038] like Figure 5 As shown, a first dynamic seal is installed at the junction of the sleeve 6 and the bottom of the protective box 5;

[0039] A second dynamic seal is installed at the junction of the power output shaft of the geared motor 9 and the protective box 5;

[0040] It should be noted that this effectively prevents lubrication leakage inside the protective box 5.

[0041] like Figure 1 , Figure 5 As shown, a first bearing is installed at the junction of the sleeve 6 and the bucket lid 3;

[0042] A second bearing, which is interference-fitted with the shaft 7, is installed at the bottom of the sleeve 6.

[0043] It should be noted that this reduces the resistance of the sleeve 6 and shaft 7 during rotation and ensures the rotational accuracy of the sleeve 6 and shaft 7.

[0044] like Figure 1 As shown, a feeding hopper 16 is installed on the upper edge of the barrel lid 3, and a discharge pipe 17 that penetrates the smelting box 1 is connected to the root of the melting barrel 2, and a control valve is installed on the discharge pipe 17.

[0045] It should be noted that aluminum-manganese raw materials are added to the inside of the melting tank 2 through the feeding hopper 16. After melting and stirring, the raw materials are discharged through the discharge pipe 17 by opening the control valve.

[0046] In use: Place the aluminum-manganese raw material into the melting barrel 2, start the electromagnetic heater 4 to heat the raw material and melt it. During the melting process, start the reduction motor 9. Through the meshing between the active bevel gear 10 and the driven bevel gear 8, the sleeve 6 and the shaft 7 move in opposite directions on the same axis. This causes the blades 11 on the sleeve 6 and the shaft 7 to stir the molten raw material, which can effectively improve the disturbance of the raw material flow field. In the process of driving the connecting frame 12 to rotate synchronously, the stirring paddle 13 will rotate under the action of the flow field disturbance, thereby disturbing the radial flow field of the raw material.

[0047] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
