Description

Technical Field

[0001] The invention relates to the technical field of vacuum degassing of aluminum solution furnaces, in particular to a degassing device for an aluminum solution insulation furnace. Background Art

[0002] Vacuum degassing of molten aluminum is a crucial step in the preparation of energy-saving building materials. It addresses the problem of molten aluminum absorbing gases during the smelting process and reacting with ambient moisture during high-temperature smelting, generating hydrogen that dissolves in the molten aluminum. During solidification, this hydrogen release forms pores, which reduce the density of energy-saving building materials, leading to decreased mechanical strength, thermal conductivity, and sound insulation.

[0003] Most existing vacuum degassing devices for aluminum solution first discharge the gas in the aluminum solution and then directly introduce inert gas into the solution.

[0004] The traditional method of directly using a vacuum pump for suction will not only cause the aluminum solution to be sucked out by the vacuum pump, but also cause hydrogen to be continuously released from the inside of the aluminum solution, resulting in hydrogen remaining above the aluminum solution. At the same time, it is easy to cause local overheating or solidification risks if it is stored in the inner tank for a long time.

[0005] Traditionally, inert gas is blown directly into the surface of the aluminum solution, thereby contacting the surface of the aluminum solution, which cannot completely contact every part of the aluminum solution. At the same time, the aluminum solution contains a large amount of hydrogen. If the interior cannot fully contact with the inert gas, an oxide film will easily form in the aluminum solution, which will cause hydrogen residue to cause porosity defects in the energy-saving building materials produced later.

[0006] Therefore, a degassing device for an aluminum solution holding furnace is proposed. Summary of the Invention

[0007] The object of the present invention is to provide a degassing device for an aluminum melt holding furnace to solve the problems raised in the above background technology.

[0010] Furthermore, the transfer component also includes a second spring symmetrically fixedly connected to the inside of the arc-shaped baffle, the bottom of each first sliding block is fixedly connected to a third spring, and the bottom of each third spring is fixedly connected to the sliding groove, and the two second springs are commonly fixedly connected to the second sliding block at one end away from the arc-shaped baffle, an ejection outlet is provided on the side wall of the cylinder, an opening is provided on the side wall of the cylinder, the outer wall of the cylinder is fixedly connected to a fixed shell, and the interior of the fixed shell is fixedly connected to a curved pipe.

[0011] Furthermore, an inert gas exhaust assembly is provided on the outer shell of the insulation furnace. The inert gas exhaust assembly includes a second vent pipe that penetrates and is fixedly connected to the interior of the fixed shell. The outer side of the insulation furnace outer shell is fixedly connected to an inert gas exhaust device.

[0012] Furthermore, an aluminum solution collecting box is fixedly connected to the bottom of the insulation furnace shell, and the bottom of the curved pipe is communicated with the aluminum solution collecting box.

[0013] Furthermore, one end of the first ventilation pipe is interconnected with the insulation furnace cover, and the other end of the first ventilation pipe is interconnected with the gas collecting box. The touch button is located on the movement path of the cone, and each group of sliding blocks is located on the movement path of two T-shaped rods respectively.

[0014] Furthermore, the arc-shaped baffle is adapted to slide inside the sliding opening, and the size of the arc-shaped baffle is adapted to the size of the notch.

[0015] Furthermore, the bottom of the second sliding block is configured as an inclined surface, and the second sliding block and the inner sliding adaptation of the arc-shaped baffle are adapted to each other, and the size of the ejection port and the size of the second sliding block are adapted to each other.

[0016] Furthermore, the size of the opening is adapted to the size of the notch, and the ejection outlet is located on the movement path of the second sliding block.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The setting of the vacuum exhaust component can not only remove the air above the aluminum solution, but also remove most of the hydrogen in the aluminum solution in a short time. At the same time, the liquid surface of the aluminum solution can be close to the bottom of the insulation furnace cover. Compared with the traditional direct suction by a vacuum pump, the aluminum solution will not be sucked out by the vacuum pump, so that there will be no residual air above the aluminum solution, which solves the problem that energy-saving building materials will not produce pores due to residual air during the later molding, and will not reduce the tensile strength and fatigue life of the energy-saving building materials during use.

[0019] The working setting of the transfer component can ensure that the gas above the aluminum liquid can be transferred away in time after it is exhausted. At the same time, during the flow of the aluminum liquid, residual hydrogen and other gases naturally float to the surface due to the density difference. With the help of the vacuum environment, the solubility is further reduced, and the degassing efficiency is accelerated. At the same time, the natural convection formed by gravity flow promotes the uniform distribution of the aluminum liquid temperature, reducing the risk of local overheating or solidification.

[0020] The arrangement of the curved pipe and the inert discharge assembly can firstly react to generate hydrogen in the aluminum solution, and at the same time, the inert gas is directly blown into the surface of the aluminum solution, so as to purge the aluminum solution continuously flowing out of the fixed shell, thereby greatly increasing the contact area between the inert gas and the aluminum solution, thereby more completely removing the hydrogen in the aluminum solution and inhibiting the formation of oxide film in the aluminum solution.

An ejection outlet 20 is opened on the side wall of the cylinder 6, and the bottom of the second sliding block 19 is set as an inclined surface. The second sliding block 19 is adapted to slide inside the arc-shaped baffle 17, and the size of the ejection outlet 20 is consistent with the size of the second sliding block 19. The inches are adapted to each other, an opening 21 is provided on the side wall of the cylinder 6, and the ejection outlet 20 and the opening 21 are both opened on the cylinder 6, and the outer wall of the cylinder 6 is fixedly connected with a fixed shell 22, and the fixed shell 22 is arranged corresponding to the positions of the opening 21 and the ejection outlet 20, and the interior of the fixed shell 22 is fixedly connected with a curved pipe 23, the size of the opening 21 is adapted to the size of the notch 13, and the ejection outlet 20 is located on the movement path of the second sliding block 19, the bottom of the ejection outlet 20 is set to a curved surface, and the bottom inclined surface of the ejection outlet 20 is adapted to the bottom inclined surface of the second sliding block 19.

[0027] The curved pipe 23 is S-shaped and fixedly wound from the top of the outer wall of the cylinder 6 to the bottom of the outer wall of the cylinder 6 .

[0028] An inert gas discharge assembly is provided on the insulation furnace shell 1, and the inert gas discharge assembly includes a second ventilation pipe 24 that penetrates and is fixedly connected to the interior of the fixed shell 22, and the second ventilation pipe 24 is sealed from the outside of the insulation furnace shell 1 to prevent leakage. The top of the curved pipe 23 and the gas outlet of the second ventilation pipe 24 are located on the same horizontal plane. An inert gas discharge device 25 is fixedly connected to the insulation furnace shell 1, and the top of the curved pipe 23 and the gas outlet of the second ventilation pipe 24 are located on the same horizontal plane, and the end of the second ventilation pipe 24 away from the curved pipe 23 is connected to the inert gas discharge device 25.

[0029] An aluminum solution collecting box 26 is fixedly connected to the bottom of the insulation furnace shell 1 , and the bottom of the curved pipe 23 is communicated with the aluminum solution collecting box 26 .

[0030] The above implementation works as follows: The initialization steps are as follows: The staff opens the insulation furnace cover 2 and pours the processed aluminum solution into the inner cavity of the circular inner tank 7, and the liquid level of the aluminum solution is kept at the same level as the top of the truncated cone 9. Then the staff closes the insulation furnace cover 2 again, and the second spring 181 is in a stretched state.

[0031] The steps for running the job are as follows: The working steps of the vacuum exhaust assembly are as follows: The staff first turns on the suction pump 3, and the suction pump 3 sucks the air inside the insulation furnace shell 1 and the cylinder 6 into the air collecting box 5 through the first ventilation pipe 4, thereby creating a vacuum environment inside the entire insulation furnace shell 1. As the suction pump 3 continuously sucks the air in the inner cavity of the cylinder 6, the atmospheric pressure inside the cylinder 6 is continuously weakened, so that the circular inner liner 7 slides vertically upward in the inner cavity of the cylinder 6 under the influence of the air pressure difference. As the circular inner liner 7 moves vertically upward, the circular inner liner 7 drives the circular table 9 to move vertically upward synchronously. When the circular table 9 moves vertically upward and contacts the touch button 10, the circular table 9 touches the touch button 10, causing the touch button 10 to control the suction pump 3 to be closed through the controller. Because the liquid level of the aluminum solution in the inner cavity of the circular inner liner 7 is maintained on the same horizontal plane as the top of the circular table 9, when the liquid level of the aluminum solution is in contact with the bottom of the insulation furnace cover 2, it means that all the air above the aluminum solution is discharged.

[0032] At the same time, during the vertical upward movement of the circular inner liner 7, the circular inner liner 7 also drives the T-shaped rod 8 vertically upward, so the T-shaped rod 8 moves vertically upward and in the direction close to the sliding protrusion 11, and when the round table 9 contacts the touch button 10, the T-shaped rod 8 pushes open the two sliding protrusions 11 on both sides and compresses the first spring 12, so that the T-shaped rod 8 is clamped on the two first springs 12, thereby keeping the round table 9 always in contact with the touch button 10, and preventing the circular inner liner 7 from slipping.

[0033] The arrangement of the vacuum exhaust assembly not only removes the air above the aluminum solution, but also removes most of the hydrogen in the aluminum solution in a short time. At the same time, the liquid surface of the aluminum solution is close to the bottom of the insulation furnace cover 2. Compared with the traditional direct suction by a vacuum pump, the aluminum solution will not be sucked out by the vacuum pump, so that there will be no residual air above the aluminum solution, which solves the problem that energy-saving building materials will not produce pores due to residual air during the later molding, and will not reduce the tensile strength and fatigue life of the energy-saving building materials during use.

[0034] The working steps of the transfer component are as follows: As described above, as the circular inner liner 7 moves vertically upward, the circular inner liner 7 drives the notch 13 to move vertically upward as well, and the notch 13 drives the arc-shaped baffle 17 to move vertically upward. At the same time, because the second spring 181 is always in a stretched state, the second sliding block 19 always contacts the inner wall of the cylinder 6, so that the arc-shaped baffle 17, the second sliding block 19 and the circular inner liner 7 form a closed space to prevent the aluminum solution from overflowing from the inner cavity of the cylinder 6. When the circular inner liner 7 drives the second sliding block 19 to move to the ejection outlet 20, the inner wall of the cylinder 6 no longer contacts the second sliding block 19, so that the second spring 181 pushes the second sliding block 19 into the inner cavity of the ejection outlet 20 through the elastic contraction force, and at the same time, the circular inner liner 7 As the circular liner 7 moves upward, the top of the inner cavity of the ejection port 20 contacts the second sliding block 19, so that the second sliding block 19 cannot move further upward, and the second sliding block 19 limits the upward movement of the arc-shaped baffle 17. As the circular liner 7 moves vertically upward, the arc-shaped baffle 17 slides vertically downward in the inner cavity of the sliding port 15 and compresses the third spring 182. At the same time, the arc-shaped baffle 17 drives the first sliding block 16 to slide vertically downward inside the sliding groove 14, so that the arc-shaped baffle 17 no longer blocks the gap 13, so that the aluminum solution gathered in the inner cavity of the circular liner 7 flows out of the gap 13 along the slope at the bottom of the circular liner 7. Similarly, because the aluminum solution has fluidity, the aluminum solution continuously enters the interior of the fixed shell 22 through the gap 13.

[0035] Thus, the aluminum solution flows from the interior of the fixed shell 22 into the inner cavity of the curved pipe 23 and continuously rolls along the inner cavity of the curved pipe 23 .

[0036] The working setting of the transfer component can ensure that the gas above the aluminum liquid can be transferred away in time after it is exhausted. At the same time, during the flow of the aluminum liquid, residual hydrogen and other gases naturally float to the surface due to the density difference. With the help of the vacuum environment, the solubility is further reduced, and the degassing efficiency is accelerated. At the same time, the natural convection formed by gravity flow promotes the uniform distribution of the aluminum liquid temperature, reducing the risk of local overheating or solidification.

[0037] The working steps of the inert gas exhaust assembly are as follows: As described above, when the aluminum solution preferentially enters the fixed shell 22, the staff opens the inert gas discharge device 25 and continuously ventilates the inert gas toward the top inlet of the curved pipe 23. As the inert gas continuously enters the inner cavity of the fixed shell 22, the atmospheric pressure is continuously increasing. The mutual engagement of the T-shaped rod 8 and the sliding protrusion 11 prevents the vertical downward movement of the circular inner liner 7. The inert gas is continuously blown onto the continuously flowing aluminum solution, thereby forming a purge of the aluminum solution. At the same time, the inert gas discharge device 25 can also continuously blow the aluminum solution toward the inner cavity of the curved pipe 23, ensuring that the aluminum solution does not remain in the inner cavity of the fixed shell 22 and flows into the inner cavity of the curved pipe 23. As a result, the hydrogen dissolved in the aluminum solution forms bubbles with the inert gas such as argon. The hydrogen enters the bubbles due to diffusion and is discharged with them, thereby reducing the hydrogen content and improving the oxidation resistance of the aluminum.

[0038] After the aluminum solution is completely poured, the inert gas also completely reacts with the hydrogen in the aluminum solution, so that the aluminum solution flows into the aluminum solution collection box 26 along the inner cavity of the curved pipe 23. The aluminum solution collection box 26 collects the degassed aluminum solution and properly stores it.

[0039] At the same time, the staff opens the insulation furnace cover 2 again and manually separates the two sliding protrusions 11 to remove the circular inner liner 7 and puts the circular inner liner 7 back into the inner cavity of the cylinder 6 to facilitate the subsequent degassing of the aluminum solution.

[0040] The arrangement of the curved pipe 23 and the inert discharge assembly can firstly react to generate hydrogen in the aluminum solution. At the same time, compared with the traditional method of blowing the inert gas directly into the surface of the aluminum solution, it can be used to blow on the aluminum solution continuously flowing out of the fixed shell 22, greatly increasing the contact area between the inert gas and the aluminum solution, thereby more completely removing the hydrogen in the aluminum solution and inhibiting the formation of an oxide film in the aluminum solution.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
