Description

Technical Field

[0001] The utility model relates to the technical field of nonferrous metal production equipment, in particular to an aluminum alloy insulation furnace with magnetic stirring. Background Art

[0002] Electromagnetic stirring devices are widely used in the aluminum casting industry and are typically installed at the bottom of the aluminum furnace. The traveling magnetic field generated by the electromagnetic stirring device passes through the furnace bottom via its salient iron poles, acting on the molten aluminum inside, causing it to move and stir. However, because the furnace bottom thickness often exceeds 500 mm, the salient iron poles of the electromagnetic stirring device are far from the molten aluminum. As a result, the magnetic field generated by the electromagnetic stirring device decays exponentially with increasing distance, reducing the device's efficiency. To address this issue, two possible technical measures are to minimize the thickness of the furnace bottom or walls or to increase the power of the electromagnetic stirring device. However, reducing the thickness of the furnace bottom or walls reduces the thermal insulation performance of the aluminum furnace, shortening its service life. Increasing the power of the electromagnetic stirring device increases equipment investment and the electromagnetic stirring power required for the furnace, increasing the construction and operating costs of the aluminum casting plant.

[0003] Patent number CN212658075U, titled "An Electromagnetic Stirring Device for an Aluminum Melting Furnace," addresses the aforementioned issues. However, the distance between the core salient pole and the extended salient pole cannot be adjusted, resulting in a constant stirring rate for the aluminum melt, which in turn reduces the stirring effect. Based on this, the present invention designs an aluminum alloy holding furnace with magnetic stirring to address the aforementioned issues. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figure 1 、 Figure 2 、 Figure 5As shown, the device includes a furnace body 1 and an isolation frame 2, the isolation frame 2 is fixed at the lower end of the interior of the furnace body 1, a stirring assembly 3 is provided inside the furnace body 1, and an adjustment assembly 4 is provided inside the isolation frame 2, the stirring assembly 3 includes an electromagnetic stirrer 301 fixed at the lower end of the interior of the furnace body 1, and magnetic pins 302 are fixed on the left and right sides of the top of the electromagnetic stirrer 301, the adjustment assembly 4 includes a protective sleeve 401 connected to the left and right sides of the top of the isolation frame 2, the internal thread of the protective sleeve 401 is provided with a magnetic sleeve 402, the magnetic sleeve 402 is sleeved on the outside of the magnetic pin 302, and the external fixed sleeve of the protective sleeve 401 is provided with a worm gear 403, a worm 404 is rotated and penetrated at the lower left end of the exterior of the furnace body 1, and the worm 404 rotates and penetrates the isolation frame 2, and the worm 404 and the worm gear 403 are in a gear meshing design.

[0029] A feed hole 5 is integrally provided at the top of the furnace body 1. The feed hole 5 is a through-hole design. A cover plate 6 is provided on the left side of the top of the furnace body 1 by a hinge and on the right side by a lock. The staff first pours the aluminum solution into the furnace body 1 through the feed hole 5, then closes the cover plate 6, and then turns on the electromagnetic stirrer 301. The magnetic force generated by the electromagnetic stirrer 301 passes through the magnetic pin 302, the magnetic sleeve 402, and the protective sleeve 401 into the furnace body 1, thereby generating a magnetic field inside the furnace body 1. Through the action of this magnetic field, the aluminum solution inside the furnace body 1 is magnetically stirred. In addition, the staff can rotate the worm 404, which drives the worm gear 403 to rotate together with the protective sleeve 401. Through the threaded transmission of the anti-slip sleeve and the magnetic sleeve 402, the magnetic sleeve 402 moves along the direction of the magnetic sleeve 402, thereby adjusting the distance between the magnetic sleeve 402 and the aluminum solution, thereby changing the intensity of the magnetic field inside the furnace body 1 and ultimately adjusting the stirring rate of the aluminum solution.

[0030] Example 2

[0031] like Figure 2 、 Figure 3 、 Figure 4As shown, the internal cross-section of the magnetic sleeve 402 and the external cross-section of the magnetic pin 302 are circular in design. The axes of the magnetic sleeves 402, the magnetic pin 302 and the protective sleeve 401 on the left and right sides are in a coaxial design state. A connecting plate 7 is fixed between each of the two magnetic sleeves 402. The connecting plate 7 and the axis of the magnetic pin 302 are in a vertical design state. The outer wall of the magnetic sleeve 402 on the left is fixed with an indicator pin 8. The indicator pin 8 slides through the furnace body 1 and the isolation frame 2. The furnace body 1 is made of heat-insulating material and the isolation frame 2 is integrally provided on the left side. There is a first give way hole 9, and a second give way hole 10 is integrally provided at the lower left end of the interior of the furnace body 1. The first give way hole 9 and the second give way hole 10 are both through-hole designs, and the first give way hole 9 and the second give way hole 10 are in a one-to-one corresponding design.

The top of the protective cover 401 is made of ferrite material and has the function of magnetic penetration.

[0032] According to the operation method in Example 1, when the protective sleeve 401 rotates, since the protective sleeve 401 and the magnetic sleeve 402 are in a threaded connection design, at this time, the connecting plate 7 limits the synchronous rotation of the magnetic sleeve 402 following the protective sleeve 401, thereby ensuring the normal up and down displacement of the magnetic sleeve 402. When the magnetic sleeve 402 moves up and down, the left magnetic sleeve 402 drives the indicator pin 8 to move along the direction of the scale 11 until the indicator pin 8 moves to the value of the scale 11 that meets the staff's requirements, that is, the stirring rate of the aluminum solution is controlled within the staff's requirements. The staff then releases the worm 404, and the first and second clearance holes 9 and 10 make room for the displacement of the indicator pin 8. When the stirring of the aluminum solution is completed, the valve 13 is opened again to discharge the aluminum solution from the discharge pipe 12 into the next process.
