Description

Technical Field

[0001] The invention relates to the technical field of aluminum liquid dehydrogenation, in particular to an aluminum liquid dehydrogenation device. Background Art

[0002] During the smelting process of aluminum alloy and other metals, there is a lot of hydrogen in the molten metal. If the hydrogen is not removed in time, it will cause defects such as shrinkage cavities and shrinkage in the formed profiles. Such defects are fatal defects for load-bearing structural parts and will seriously reduce the structural strength and life of the structural parts. Therefore, hydrogen must be removed in time during the smelting process.

[0003] The existing Chinese patent application with publication number CN111363932B discloses a dehydrogenation device for aluminum liquid smelting for cast aluminum plates, in order to solve the problem that in the process of aluminum liquid smelting for cast aluminum plates, there are still a large number of small bubbles that have not yet floated or are floating inside the aluminum liquid, these bubble lava is difficult to observe, and the number is huge. Since the aluminum liquid has a certain viscosity, coupled with the obstruction of the slag inside the aluminum liquid, it takes a certain amount of time for these small bubbles to float up, including the main body of the equipment; the main body of the equipment is a regular six-sided columnar tank structure as a whole, and the upper end of the tank mouth of the main body of the equipment is sealed with a top sealing mechanism. In the present invention, since the left and right edges of the side walls corresponding to the installation position of the defoaming box on the main body of the equipment are fixedly installed with vertical guide rails, coupled with the obstruction of the slag inside the aluminum liquid, it takes a certain amount of time for the small bubbles generated in the aluminum liquid to float up, so it is necessary to stand for a period of time to produce scum, and the scum can be removed to complete the dehydrogenation.

[0004] However, the dehydrogenation device has the following defects when used:

[0005] 1. When the existing aluminum liquid dehydrogenation device is in use, the fineness of the bubbles determines the dehydrogenation effect of the aluminum liquid to a certain extent. In the existing aluminum liquid dehydrogenation device, the inert gas is only sprayed into the aluminum liquid through the rotating rotor to form a large number of dispersed small bubbles, so as to perform degassing and refining treatment. However, this type of injection method is difficult to further increase the number of inert gas bubbles and reduce the diameter of the inert gas bubbles. At the same time, it is also difficult to ensure that the inert gas bubbles stay in the aluminum liquid for a longer time. Therefore, the overall dehydrogenation effect needs to be improved;

[0006] 2. It is difficult to maintain the flow state of the molten aluminum when the existing molten aluminum dehydrogenation device is in use, resulting in the temperature of the molten aluminum changing with mixing and subsequent standing process during the dehydrogenation process, which is not conducive to the overall dehydrogenation effect. Therefore, it is urgently needed to be improved. Summary of the invention

[0041] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0042] 1. In the aluminum liquid dehydrogenation device, an inert gas is introduced into the circular cavity through a gas injection structure, and then the driving component is used to drive the mixing component, so that the mixing component breaks the rotor rotating at a high speed of the inert gas into numerous small bubbles, which diffuse and rise in the aluminum liquid, thereby removing hydrogen. In the process of rising, the small bubbles, due to the effect of surface tension, bring a part of the inclusions from the aluminum liquid to the liquid surface, forming scum, thereby removing the inclusions in the aluminum liquid. At the same time, the whole device is divided into several circular cavities, and several circular cavities are filled with a number of aluminum liquids, so that the dehydrogenation treatment of the aluminum liquid is more refined, and combined with the stirring effect of the mixing component in the circular cavity, the alloy composition in the aluminum liquid is more uniform, which is more conducive to the long-term and efficient operation of the whole device;

[0043] 2. In the aluminum liquid dehydrogenation device, the first rotating shaft can be driven to rotate by the arranged driving assembly, so that the supporting frame and the first conical block can rotate. Since the side of the first conical block fits the inner wall of the second conical cavity, the annular opening and the branch channel are connected, so that the inert gas can enter the annular opening and the hollow cavity, and then spray out through a plurality of air holes and be inside the third conical cavity. The plurality of air holes divide the inert gas into fine bubbles. At this time, the ultrasonic generator is started to make the ultrasonic probe emit ultrasonic waves, and the ultrasonic waves further break the inert gas into smaller pieces, so as to help the degassing and refining effect. Moreover, since the first conical block is at the inner bottom end of the circular cavity, the tiny bubbles can move from top to bottom, so that the bubbles are in contact with the aluminum liquid for a longer time, which can further improve the degassing effect.

[0044] 3. In the aluminum liquid dehydrogenation device, when the first conical block rotates, the arc cover will rotate accordingly, and the tiny bubbles in the third conical cavity inside the first conical block will float up by buoyancy. At the same time, under the action of the rotation of the first conical block, the tiny bubbles will generate centrifugal force. Through the arc cover with an outward-expanding arc structure, the tiny bubbles are affected by the centrifugal force and guided by the arc cover during the floating process, and approach the inner wall of the circular cavity, so that the tiny bubbles located in the middle of the bottom end of the circular cavity will diffuse outward and float upward, so that the tiny bubbles are dispersed more evenly, thereby increasing the contact range between them and the aluminum liquid, and further ensuring the degassing effect;

[0045] 4. In the aluminum liquid dehydrogenation device, when the first rotating shaft rotates, the stirring plate rotates accordingly. During the rotation of the stirring plate, the second magnets at the two edges of the top of the stirring plate and the first magnet at the bottom of the support plate are affected by the magnetic force. The two will attract each other or move away from each other, so that when the stirring plate is rotated to the bottom of the support plate, the stirring plate will be deflected. Since one second magnet corresponds to the first magnet at the bottom of two support plates, when the second magnet is magnetically attracted to the first magnet at the bottom of one of the support plates, the second magnet will be magnetically attracted to the first magnet at the bottom of the other support plate. Therefore, the stirring plate will flip back and forth when passing through the first magnets at the bottom of the two support plates in sequence, and the flipping of the stirring plate will make the contact between the aluminum liquid and the bubbles more uniform, so as to ensure the degassing effect.

[0046] 5. In the aluminum liquid dehydrogenation device, when the first rotating shaft rotates, the fan blades will rotate accordingly, and then after the heating tube is started, a certain threshold temperature is generated inside the heating tube, and then the fan blows the air into the annular cavity and into the hollow structure of the stirring plate. The heat-conducting material of the stirring plate is used to heat the aluminum liquid during the stirring process to ensure the flow state of the aluminum liquid and thus ensure the degassing effect.

[0068] See also Figure 1-Figure 10 , a molten aluminum dehydrogenation device, comprising a device barrel 1, a gas injection structure 2, a mixing component 3 and a driving component 4. Among them:

[0069] The device barrel 1 is a cylindrical structure, and at least four circular cavities 11 are opened at equal intervals in the circumferential direction of the device barrel 1. The top of the device barrel 1 is also provided with a feed port 12 connected to the four circular cavities 11 one by one. The bottoms of the four circular cavities 11 are sequentially provided with a first conical cavity 111 and a second conical cavity 112 from top to bottom. The cross-sectional area of ​​the first conical cavity 111 gradually decreases from top to bottom, and the cross-sectional area of ​​the second conical cavity 112 gradually increases from top to bottom. In addition, the device barrel 1 is also provided with a feed port 12 connected to the four circular cavities 11. The discharge cavity 14 is below the cavity 11, and a discharge pipe 13 extending to the inside of the discharge cavity 14 is provided at the bottom of the side of the device barrel 1. Valves are provided inside the feed port 12 and the discharge pipe 13. When in use, aluminum liquid can be injected into the circular cavity 11 through the set feed port 12, and the valve on the discharge pipe 13 is closed at the same time, and the valve at the feed port 12 is closed after a certain amount of injection. In this embodiment, the device barrel 1 is made of transparent material. Correspondingly, as other embodiments, other materials can also be used, depending on the manufacturer;

[0070] In addition, the gas injection structure 2 is arranged inside the device barrel 1, and the gas injection structure 2 is used to inject the inert gas into the circular cavity 11. The number of mixing components 3 is the same as the number of circular cavities 11 and they are arranged one by one inside the circular cavity 11. The mixing components 3 are used to make the aluminum liquid in the circular cavity 11 contact with the inert gas. The driving component 4 is arranged above the device barrel 1, and the driving component 4 is used to drive the mixing component 3 to rotate. When the aluminum liquid is inside the circular cavity 11, the inert gas enters the inside of the circular cavity 11 through the arranged gas injection structure 2, and then the driving component 4 is used to drive the mixing component 3, so that the mixing The mixing component 3 breaks the high-speed rotating rotor of the inert gas into countless small bubbles, which diffuse and rise in the aluminum liquid, thereby removing hydrogen. In the process of rising, due to the effect of surface tension, the small bubbles bring a part of the inclusions from the aluminum liquid to the liquid surface, forming scum to remove the inclusions in the aluminum liquid. At the same time, the entire device is divided into several circular cavities 11, and several circular cavities 11 are each filled with a plurality of aluminum liquids, so that the dehydrogenation treatment of the aluminum liquid is more refined, and combined with the stirring effect of the mixing component 3 in the circular cavity 11, the alloy composition in the aluminum liquid is more uniform, which is more conducive to the long-term and efficient operation of the entire device.

[0071] Specifically, the gas injection structure 2 includes a main channel 21, a branch channel 22 and an air pipe 23, wherein the main channel 21 is vertically opened at the center of the device barrel 1, and the top of the main channel 21 extends to the outer top of the device barrel 1, the number of branch channels 22 is the same as the number of circular cavities 11 and corresponds one to one, the branch channel 22 is horizontally opened inside the device barrel 1, one end of the branch channel 22 is connected to the second conical cavity 112, and the other end of the branch channel 22 is connected to the inner bottom end of the main channel 21, and one end of the air pipe 23 is connected to the top of the main channel 21, and a valve is arranged inside the air pipe 23.

[0072] When the gas injection structure 2 is in use, after injecting inert gas into the trachea 23 (the other end of the trachea 23 is transported to the inside of the bronchus 23 by an external delivery pump or other structure, not shown in the figure), the inert gas can enter the inside of each branch channel 22 through the main channel 21.

[0073] Furthermore, in order to make the inert gas flow reasonably, the mixing assembly 3 includes a first rotating shaft 31, a first conical block 32 and a supporting frame 33, wherein the first rotating shaft 31 is vertically arranged at the center of the circular cavity 11, a third conical cavity 321 is opened on the top of the first conical block 32, and a hollow cavity 323 is opened inside the first conical block 32, the hollow cavity 323 and the third conical cavity 321 are connected through a plurality of air holes 322, an annular opening 324 is opened on the side of the first conical block 32, and the annular opening 324 is used to connect the hollow cavity 323 and the branch channel 22, the supporting frame 33 is fixed to the inner top end of the first conical cavity 111, the bottom end of the first rotating shaft 31 is fixed to the top end of the supporting frame 33, and the cross-sectional area of ​​the first conical block 32 gradually increases from top to bottom, and the side of the first conical block 32 cooperates with the inner side wall of the second conical cavity 112.

[0074] Furthermore, the mixing component 3 also includes an opening cavity 311, an ultrasonic transmitter 34 and an ultrasonic probe 35, wherein the opening cavity 311 is opened inside the first rotating shaft 31, the ultrasonic transmitter 34 is arranged inside the opening cavity 311, the ultrasonic probe 35 is arranged on the ultrasonic transmitter 34, and the bottom end of the ultrasonic probe 35 passes through the inside of the third conical cavity 321.

[0075] That is, when in use, the driving assembly 4 is arranged to drive the first rotating shaft 31 to rotate, thereby rotating the supporting frame 33 and the first conical block 32. Since the side of the first conical block 32 fits the inner wall of the second conical cavity 112, the annular opening 324 is connected to the branch channel 22, thereby allowing the inert gas to enter the annular opening 324 and the hollow cavity 323, and then spray out through the plurality of air holes 322 and be inside the third conical cavity 321. The plurality of air holes 322 divide the inert gas into fine bubbles. At this time, the ultrasonic generator is started to make the ultrasonic probe 35 emit ultrasonic waves. The ultrasonic waves further break the inert gas into smaller pieces, thereby contributing to the degassing and refining effect. Moreover, since the first conical block 32 is at the inner bottom end of the circular cavity 11, the tiny bubbles can move from top to bottom, thereby making the bubbles contact with the aluminum liquid for a longer time, thereby further improving the degassing effect.

[0076] Furthermore, an arc cover 36 is fixed on the top of the first conical block 32, and the longitudinal section of the arc cover 36 is an arc structure that spreads outward from the center of the first conical block 32, that is, Figure 5 and Figure 7It can be seen that when the first conical block 32 rotates, the arc cover 36 will rotate accordingly, and the tiny bubbles in the third conical cavity 321 inside the first conical block 32 will float up due to buoyancy. At the same time, under the action of the rotation of the first conical block 32, the tiny bubbles will generate centrifugal force. Through the arc cover 36 with an outward-expanding arc structure, the tiny bubbles are affected by the centrifugal force and guided by the arc cover 36 during the floating process and approach the inner wall of the circular cavity 11, so that the tiny bubbles located in the middle of the bottom end of the circular cavity 11 will diffuse outward and float upward, so that the tiny bubbles are dispersed more evenly, thereby increasing their contact range with the aluminum liquid and further ensuring the degassing effect.

[0077] At the same time, in order to help the aluminum liquid and the bubbles to achieve better combination, an auxiliary stirring component 5 is also arranged on the outside of the first rotating shaft 31, and the auxiliary stirring component 5 includes a stirring plate 51, a support plate 52, a first magnet 53 and a second magnet 54, wherein the stirring plate 51 is rotatably connected to the outside of the first rotating shaft 31, and the interior of the stirring plate 51 is a hollow structure, a second magnet 54 is eccentrically arranged on the top of the stirring plate 51, and the second magnet 54 is located at the end of the stirring plate 51 away from the first rotating shaft 31, the support plate 52 is fixed on the inner wall of the circular cavity 11 and is located above the second magnet 54, the first magnet 53 is arranged at the bottom of the support plate 52 and cooperates with the second magnet 54, then, when the first rotating shaft 31 rotates, the stirring plate 51 rotates accordingly, and when the stirring plate 51 During the rotation process, the second magnets 54 at the two edges of the top of the stirring plate 51 and the first magnets 53 at the bottom of the support plate 52 are affected by the magnetic force, and the two will attract each other or move away from each other, so that when the stirring plate 51 is rotated to the bottom of the support plate 52, the stirring plate 51 will be deflected. Since one second magnet 54 corresponds to the first magnets 53 at the bottom of two support plates 52, when the second magnet 54 is magnetically attracted to the first magnet 53 at the bottom of one of the support plates 52, the second magnet 54 will be magnetically attracted to the first magnet 53 at the bottom of the other support plate 52. Therefore, the stirring plate 51 will flip back and forth when passing through the first magnets 53 at the bottom of the two support plates 52 in sequence, and the flipping of the stirring plate 51 will make the contact between the aluminum liquid and the bubbles more uniform, so as to ensure the degassing effect.

[0078] Of course, in order to ensure the stability of the stirring plate 51, a torsion spring is also provided at the rotation connection between the stirring plate 51 and the first rotating shaft 31. The rotation performance of the torsion spring makes the stirring plate 51 turn over more smoothly.

[0079] In addition, in order to ensure subsequent material discharge, the mixing component 3 also includes a central cavity 325, pillars 37 and a second conical block 38, wherein the central cavity 325 is opened inside the first conical block 32, and the top of the central cavity 325 is connected to the inner bottom end of the third conical cavity 321, and the bottom end of the central cavity 325 extends to the outer bottom of the first conical block 32, the number of pillars 37 is the same as the number of circular cavities 11 and corresponds one to one, and the bottom of the pillars 37 is fixed to the inner bottom end of the discharge cavity 14, the top of the pillars 37 extends to the inside of the central cavity 325 and is fixed with the second conical block 38, and the outer side of the second conical block 38 cooperates with the inner side wall of the third conical cavity 321. A lifting assembly 6 is also provided at the top of the device barrel 1, and the lifting assembly 6 includes a telescopic cylinder 61, an electric telescopic rod 62 and a top plate 63, wherein the telescopic cylinder 61 and the electric telescopic rod 62 are both arranged at the top of the device barrel 1, and the telescopic ends of the telescopic cylinder 61 and the electric telescopic rod 62 are both connected to the bottom of the top plate 63, and the top end of the first rotating shaft 31 passes through the top plate 63 and is rotatably connected to the top plate 63.

[0080] Therefore, when in use, after the electric telescopic rod 62 is started, the electric telescopic rod 62 drives the top plate 63 to descend, so that the driving assembly 4 and the mixing assembly 3 are descended, and then the first conical block 32 begins to descend. When the first conical block 32 descends, a gap is generated between its outer side and the inner wall of the second conical cavity 112, and a gap is also generated between the inner wall of the third conical cavity 321 and the outer side of the second conical block 38, so as to complete the removal of the aluminum liquid. The degassed aluminum liquid will enter the inside of the discharge cavity 14, which is conducive to the subsequent unified discharge. In addition, it is worth mentioning that in order to ensure the feeding effect, a silicone one-way valve nozzle is provided inside the air hole 322 to prevent the aluminum liquid from entering the air hole 322 and the hollow cavity 323.
