Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy smelting furnace structures, and in particular to an energy-saving double-vortex well aluminum alloy smelting furnace. Background Art

[0002] The aluminum alloy melting furnace is a new, highly efficient and energy-saving aluminum melting furnace developed based on the aluminum smelting process. It is primarily used for melting and maintaining the heat of aluminum ingots, effectively meeting the requirements of aluminum smelting processes. The furnace consists of a melting furnace, crucible, heating elements, a furnace lid lifting mechanism, and an electrical automatic temperature control system. The furnace shell is welded cylindrically from sections of steel and steel plates. A hole is located at the lower front end of the furnace body to allow the molten liquid in the crucible to drain out of the furnace if cracks develop due to corrosion or oxidation, thus protecting the working chamber and hearth.

[0003] Most traditional aluminum alloy melting furnaces adopt a single melting chamber design, in which the aluminum material is directly heated and melted by a heating device. However, this design has many shortcomings, which limit the further improvement of melting efficiency and quality. First, during the melting process, the aluminum liquid comes into contact with oxygen in the surrounding environment, and oxidation reactions easily occur, generating impurities such as aluminum oxide. These impurities not only reduce the purity of the aluminum liquid, but may also affect the performance of subsequent processed products. In order to reduce oxidation, traditional methods often require the continuous introduction of inert gas for protection during the melting process. However, this method has low utilization efficiency of the inert gas and it is difficult to achieve sufficient mixing of the gas and the aluminum liquid, resulting in limited deoxidation effect. Summary of the Invention

[0040] Furthermore, a feed funnel 106 is fixedly connected to the upper surface of the support plate 105 and the feed pipe 104, a gas collecting box 109 is fixedly connected to one side of the smelting furnace body 101, an exhaust pipe 108 is fixedly connected to one side of the gas collecting box 109, a discharge pipe 110 is fixedly connected to one side of the lower surface of the smelting furnace body 101, and a first air inlet pipe 107 is fixedly connected to one side of the smelting furnace body 101, wherein a heating device is provided in the first well 214 and the second well 311 of the equipment, and the heating device is a conventional device in the field where the smelting furnace is located, and therefore is not elaborated in detail in the present invention. Furthermore, each connection part of the equipment is provided with a sealing structure to prevent leakage of gas and melt.

[0041] Furthermore, a U-shaped groove is opened in the lower surface of the top plate 103, and the lower surface of the top plate 103 is rotatably connected to a connecting pipe 212 through an axial ring. The other end of the connecting pipe 212 is fixedly connected to the upper surface of the connecting cross bar 202 through an axial ring. Both sides of the connecting cross bar 202 are fixedly connected with symmetrically distributed semicircular arc plates 207, wherein the U-shaped groove allows external inert gas to be introduced into the melt through the connecting pipe 212 and the driving rod 213. Further, the connecting cross bar 202 is used to transmit the driving force exerted on the fan blade 210 to it, so that the stirring shear plate 206 is rotated.

[0042] Furthermore, an annular plate 201 is fixedly connected to the lower surface of the top plate 103, an inclined air pipe 208 is fixedly connected inside the annular plate 201, and a second air inlet pipe 208 is connected through the outer surface of the connecting ring 102, wherein one side of the inclined air pipe air outlet is facing the side of the fan blade 210, and the inert gas between the connecting ring 211 and the connecting ring 102 is introduced into the equipment through the second air inlet pipe, thereby reducing the oxygen content inside the equipment and improving the smelting effect of the equipment to a certain extent.

[0043] Furthermore, a rotating groove is provided on the upper surface of the smelting furnace body 101, and a fan blade 210 is slidingly provided on the upper surface of the rotating groove. A connecting ring 211 is fixedly connected to one side of the fan blade 210, and the lower surface of the connecting ring 211 is fixedly connected to the upper surface of the annular plate 201. A hollow groove 203 is provided in the stirring shear plate 206. The hollow groove 203 provided in the stirring shear plate 206 allows the stirring shear plate 206 to form a vortex as much as possible when rotating, thereby improving the mixing efficiency to a certain extent and improving the smelting effect of the equipment.

[0044] Furthermore, a first electromagnetic coil 205 is fixedly connected to the inside of the smelting furnace body 101, a coil control box 204 is fixedly connected to the side of the outer surface of the smelting furnace body 101 close to the first electromagnetic coil 205, and a flow tube 209 is fixedly connected to the connecting ring 211. The first electromagnetic coil 205 is set so that the magnetic field penetrates the aluminum liquid and induces a toroidal eddy current, which couples with the magnetic field to generate a tangential Lorentz force, driving the melt to rotate. At the same time, the side wall eddy current can be used to specifically eliminate the dead zone at the edge of the molten pool.

[0045] Working principle: Aluminum material is introduced into the smelting furnace body 101 through the feed funnel 106, the first air inlet pipe 107, the exhaust pipe 108, the gas collection box 109 and the discharge pipe 110. Furthermore, the gas introduced into the smelting furnace body 101 is collected and buffered by the gas collection box 109, thereby preventing the gas introduced into the equipment from being directly discharged to a certain extent, thereby reducing the impact on the external environment.

[0046] By using the first electromagnetic coil 205, the stirring shear plate 206, the semicircular arc plate 207, the second air inlet pipe 208, the circulation pipe 209, the fan blade 210, the connecting ring 211, the connecting pipe 212, the driving rod 213 and the first well groove 214, the second air inlet pipe 208 introduces the inert gas into the interior of the smelting furnace body 101, so that the second air inlet pipe 208 blows the gas toward the side of the fan blade 210. Furthermore, when the fan blade 210 slides in the equipment, it drives the connecting ring 211 and the annular plate 201 to rotate synchronously. The annular plate 201 then synchronously drives the connecting crossbar 202, thereby synchronously driving the stirring shear plate 206, thereby stirring the liquid inside the first well 214 for the first time, forming a first vortex. The first electromagnetic coil 205 is then used to cause the liquid in the first well 214 to form a second vortex, and the flow direction of the second vortex is opposite to that of the first vortex. The shear force generated by the two vortexes is used to fully mix the liquid and the introduced inert gas, thereby improving the smelting effect of the equipment to a certain extent.

[0047] By using the fixed guide rail 301, the electric telescopic rod 302, the material separator 303, the limit plate 304, the T-shaped groove 305, the fixed rod 306, the teardrop-shaped cross-section plate 307 and the second electromagnetic coil 308, the liquid inside the first well 214 is completely melted, and then the material separator 303 is used to connect the first well 214 and the second well 311 through the engaging groove 312 and the movable groove 313, so that the completely melted aluminum material inside the first well 214 is introduced into the second well 311. Furthermore, the liquid is driven by the second electromagnetic coil 308, and the rotating liquid is simply blocked by the teardrop-shaped cross-section plate 307, and the inert gas is again introduced into the interior of the equipment through the air guide groove 314 and the air supply pipe 310, so that the molten liquid maintains a certain temperature and flow effect in the second well 311.

[0048] Example 2:

[0049] Reference Figure 2 - Figure 7 , the difference compared to the first embodiment is that: an annular groove 309 is opened at the bottom of the smelting furnace body 101, a second electromagnetic coil 308 is fixedly connected to the annular groove 309, and an air supply pipe 310 is fixedly connected to the second well groove 311, wherein, when the second electromagnetic coil 308 allows the solution to flow from the first well groove 214 to the inside of the second well groove 311, it maintains a certain degree of mixing effect.

[0050] Furthermore, a movable groove 313 is provided in the melting furnace body 101, and a symmetrically distributed fixed guide rail 301 is fixedly connected to one side of the melting furnace body 101, and a limiting plate 304 is fixedly connected to the fixed guide rail 301 away from the melting furnace body 101. An electric telescopic rod 302 is fixedly connected in the limiting plate 304, and a material separation plate 303 is slidably connected to the upper surface of the engaging groove 312 and the inner surface of the movable groove 313. One end of the telescopic axis of the electric telescopic rod 302 is fixedly connected to one end of the material separation plate 303, and a T-shaped groove 305 is provided in the fixed guide rail 301. The fixed guide rail 301 and the limiting plate 304 cooperate with each other, so that the material separation plate 303 can connect the first well 214 with the second well 311 under the drive of the electric telescopic rod 302, and the distance the material separation plate 303 is moved can also be used to control the flow rate of the molten metal in the first well 214.

[0051] Working principle: First, the aluminum material enters the first well 214 through the feed funnel 106. The built-in heating device (conventional resistance / induction heating) melts the aluminum material into liquid. When the first electromagnetic coil 205 is energized, an alternating magnetic field is generated, inducing the aluminum liquid to form a first vortex, evenly distributing heat and preliminarily breaking the oxide film. The second air inlet pipe 208 introduces inert gas into the smelting furnace body 101. The gas is blown toward the fan blade 210 through the inclined air pipe. The gas drives the fan blade 210 to rotate, driving the connecting ring 211, the annular plate 201 and the connecting cross bar 202 to rotate synchronously, driving the stirring shear plate 206 to form a second vortex. The first vortex and the second vortex are in opposite directions, forming a strong shear layer at the aluminum liquid interface, efficiently tearing the oxide film and stripping off impurities. The inert gas is injected into the aluminum liquid through the one-way gas groove 215 of the driving rod 213, thereby reducing the degree of oxygen oxidation of the aluminum solution.

[0052] Secondly, after the smelting of the first well trough 214 is completed, the electric telescopic rod 302 pushes the partition plate 303 to slide along the fixed guide rail 301, connecting the first well trough 214 and the second well trough 311, and the aluminum liquid flows into the second well trough 311 through the guide channel. The second electromagnetic coil 308 is started to induce the aluminum liquid to form a low-speed laminar flow to stabilize the alloy composition. The teardrop-shaped cross-section plate 307: fixed on the inner wall of the second well trough 311, its streamlined design has the following effects on the flow of aluminum liquid: turbulence suppression: the flow mode of the aluminum liquid is changed from turbulent to laminar flow, reducing the risk of secondary oxidation, impurity aggregation: high-density impurities gather in the low-pressure area on the back flow side of the teardrop-shaped cross-section plate 307, and are periodically discharged through the bottom discharge pipe 110. The air supply pipe 310 injects inert gas along the side wall of the second well trough 311, and the gas is evenly diffused through the gas guide groove 314 to form an air film covering the surface of the aluminum liquid, thereby reducing the oxygen content;

[0053] Finally, the second electromagnetic coil 308 is arranged in a ring at the bottom of the second well groove 311, and induces the aluminum liquid to oscillate slightly through a low-frequency magnetic field to further refine the grains. The separator 303 is linked to the electric telescopic rod 302 through the T-shaped groove 305, so that the first well groove 214 and the second well groove 311 can be separated or connected.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
