Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid aluminum refining, and particularly relates to an online liquid aluminum refining and degassing device for a large integrated die casting device. BACKGROUND

[0002] At present, the mixed liquid aluminum in a molten state usually needs to undergo at least one refining and impurity removing operation before being die cast by a die casting machine, that is, a predetermined amount of powdered refining agent is introduced into the mixed liquid aluminum, so that the refining agent reacts with the oxide impurities and hydrogen in the liquid aluminum, so that the content of the oxide impurities and hydrogen in the mixed liquid aluminum can be reduced to below the preset standard, thereby avoiding a too high defective rate of the products formed by die casting.

[0003] It can be known that the powdered refining agent can quickly react with the oxide impurities and hydrogen in the mixed liquid aluminum to achieve the refining purpose, but most of the powdered refining agent introduced can only fall on the liquid surface position of the mixed liquid aluminum, and it is difficult to quickly sink to the bottom position of the mixed liquid aluminum, which makes it difficult for the oxide impurities and hydrogen at the bottom position of the mixed liquid aluminum to contact and react with the refining agent, so that the content of the oxide impurities and hydrogen at the bottom position of the mixed liquid aluminum is still higher than the preset standard. In addition, if the mixed liquid aluminum flows for a shorter time in the refining device, the oxide impurities and hydrogen at the bottom position of the mixed liquid aluminum will not have enough time to react with the refining agent after the refining agent sinks to the bottom.

[0023] It can be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of one element can be one, and in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as a limitation on the number.

[0024] Reference Figures 1 to 5 The aluminum liquid online refining degassing equipment for large-scale integrated die casting device according to a preferred embodiment of the present application will be described in detail below, which comprises a container body 10 and a stirring driving assembly 20.

[0025] Specifically, the container body 10 has an inlet channel 101, an outlet channel 102 and a refining channel 103 arranged between the inlet channel 101 and the outlet channel 102 and communicating with both the inlet channel 101 and the outlet channel 102.

[0026] It is appreciated that the refining passage 103 is used as a location for the reaction of the oxide impurities and hydrogen in the mixed aluminum liquid with the refining agent, whereby the mixed aluminum liquid is introduced into the refining passage 103 from the liquid inlet passage 101, and after the refining operation in the refining passage 103, the mixed aluminum liquid is discharged from the liquid outlet passage 102.

[0027] The driving and stirring assembly 20 is arranged in the container body 10 to stir the mixed aluminum liquid in the refining passage 103, so that the refining agent and the mixed aluminum liquid are uniformly mixed, thereby enabling the oxide impurities and hydrogen in the mixed aluminum liquid to fully react with the refining agent.

[0028] Further, the container body 10 is recessed from the top to the bottom by a predetermined length to form a driving and stirring passage 104, which is communicated with the refining passage 103, so that the driving and stirring assembly 20 at least partially penetrates into the refining passage 103, thereby enabling the mixed aluminum liquid and the refining agent in the refining passage 103 to be stirred.

[0029] In a preferred embodiment, as shown in Figure 2 The refining passage 103 is arranged to be formed at a position lower than the formed positions of the liquid inlet passage 101 and the liquid outlet passage 102. In this way, the length of the refining passage 103 is extended, so that the mixed aluminum liquid stays in the refining passage 103 for a longer time, thereby enabling the refining agent to have sufficient time to contact and react with the oxide impurities and hydrogen at the bottom position of the mixed aluminum liquid under the stirring action, thereby reducing the content of the oxide impurities and hydrogen at different positions of the mixed aluminum liquid.

[0030] Specifically, the driving and stirring assembly 20 comprises a driving unit 21, an output shaft 22, and a stirring member 23, wherein the output shaft 22 is rotatably connected to the driving unit 21, and the output shaft 22 at least partially penetrates into the refining passage 103 and the driving and stirring passage 104, and is arranged on the axis of the driving and stirring passage 104, and further, the output shaft 22 has a conveying passage 2201 in the inside thereof, which is communicated with the refining passage 103 and has an outlet close to the bottom of the refining passage 103, for the passage of inert gas and refining agent. The stirring member 23 is connected to the end of the output shaft 22 away from the driving unit 21, and the stirring member 23 is arranged to be rotatable in the refining passage 103 when the driving unit 21 drives the output shaft 22, so as to stir the mixed aluminum liquid in the refining passage 103.

[0031] Those skilled in the art will understand that when the mixed aluminum liquid flows through the refining channel 103 and an inert gas such as nitrogen and a refining agent are simultaneously introduced into the conveying channel 2201, the drive unit 21 is activated to drive the output shaft 22 to rotate, so that the stirring element 23 stirs the mixed aluminum liquid along the axial direction of the output shaft 22. At the same time, the gas flowing out from the outlet of the conveying channel 2201 forms a vortex at the bottom of the mixed aluminum liquid, causing the mixed aluminum liquid to be churned from bottom to top. Meanwhile, the refining agent flowing out from the outlet of the conveying channel 2201 follows the vortex and gradually comes into contact with the churning mixed aluminum liquid, thereby causing the oxide impurities and hydrogen in the mixed aluminum liquid to be reacted.

[0032] In this way, the mixed aluminum liquid located in the refining channel 103 can come into contact with the refining agent from the surface to the bottom. This allows the oxide impurities and hydrogen in the mixed aluminum liquid to react fully with the refining agent and gradually reduce their content to below the preset standard. As a result, the number of unqualified products formed by die casting the mixed aluminum liquid is greatly reduced.

[0033] In one embodiment, the drive unit 21 is implemented as a drive motor, the output end of which is rotatably connected to the output shaft 22 to drive the output shaft 22 to rotate.

[0034] In a specific example, such as Figure 5 As shown, the drive unit 21 includes a drive member 211, a transmission member 212, and a rotating member 213. The drive member 211 is drivably connected to the input end of the transmission member 212, and the rotating member 213 is rotatably connected to the output end of the transmission member 212. The output shaft 22 is connected to the other end of the rotating member 213, so that when the drive member 211 drives the transmission member 212, the output shaft 22 is driven to rotate axially following the rotating member 213. It should be noted that in this example, the drive member 211 is implemented as a motor, the transmission member 212 is implemented as including but not limited to a belt drive or a gear drive, and the rotating member 213 is implemented as a rotary joint.

[0035] Preferably, the drive unit 21 is further provided with a housing 214, which is arranged around the transmission member 212 to form a storage cavity 21401, and the transmission member 212 is housed in the storage cavity 21401 to prevent the transmission member 212 from being covered by dust and affecting the transmission effect.

[0036] In one embodiment, the conveying channel 2201 is provided to extend through both ends of the output shaft 22 to introduce gas and refining agent from the axial direction of the output shaft 22 into the refining channel 103.

[0037] It is worth mentioning that since the output shaft 22 is arranged on the axis of the stirring passage 104, and the stirring member 23 is arranged on the axis of the stirring passage 104, when the stirring member 23 is driven to rotate, the stirring member 23 is difficult to contact the inner wall of the stirring passage 104 to avoid being abraded.

[0038] Preferably, the stirring member 23 is uniformly provided with a plurality of blade portions 231 in the circumferential direction, and each of the blade portions 231 of the stirring member 23 is at least partially arranged in the refining passage 103. Each of the blade portions 231 of the stirring member 23 is arranged in the radial direction of the output shaft 22 and forms a predetermined angle with the axial direction of the output shaft 22, so as to increase the contact surface of the blade portions 231 for stirring and mixing the aluminum liquid, and thereby increase the range of vortex generated by stirring when the stirring member 23 rotates with the output shaft 22, so as to fully mix and react the aluminum liquid and the refining agent.

[0039] Further, the aluminum liquid online refining and degassing device for large-scale integrated die casting device further comprises a material feeding unit 30. Specifically, the material feeding unit 30 comprises a gas feeding member 31 and an agent feeding member 32. The gas feeding member 31 is used to feed inert gas such as nitrogen into the conveying passage 2201. The agent feeding member 32 is used to feed refining agent into the conveying passage 2201.

[0040] Preferably, the gas feeding member 31 comprises a gas storage device 311 and a gas feeding device 312. The gas storage device 311 is connected to the gas feeding device 312, and the gas feeding device 312 is further connected to the inlet of the conveying passage 2201. The gas feeding device 312 is arranged to guide the gas from the inside of the gas storage device 311 to the conveying passage 2201.

[0041] Preferably, the gas feeding device 312 is implemented as a gas pump.

[0042] Preferably, the agent feeding member 32 comprises an agent storage device 321, an agent feeding pipeline 322, and an agent feeding device 323. The agent storage device 321 is connected to the agent feeding device 323, and the inside of the agent storage device 321 is arranged to store a predetermined amount of refining agent. Two ports of the agent feeding pipeline 322 are respectively connected to the agent feeding device 323 and the conveying passage 2201. The agent feeding device 323 is arranged to guide the refining agent in the inside of the agent storage device 321 to the agent feeding pipeline 322.

[0043] Preferably, the agent feeding device 323 is arranged as a blade screw conveyor driven by a motor.

[0044] It is understood that when the mixed aluminum liquid is introduced into the refining channel 103, the gas feeding member 312 guides the gas to be introduced into the output channel 2201, and the agent feeding member 323 feeds the refining agent stored in the agent storage 321 to the agent feeding channel 322, so that the gas and the refining agent are both introduced into the delivery channel 2201 and gradually introduced into the refining channel 103.

[0045] In a preferred embodiment, the gas feeding member 312 is arranged to communicate with the end of the agent feeding channel 322, so that when the gas feeding member 312 guides the gas to be introduced into the delivery channel 2201, the refining agent introduced into the agent feeding channel 322 can be blown by the gas guided by the gas feeding member 312 to the delivery channel 2201, so that the refining agent can be quickly contacted with the mixed aluminum liquid.

[0046] In addition, the aluminum liquid online refining and degassing device for large integrated die casting device further comprises a lifting device 40, which is used to separate the container body 10 and the stirring assembly 20 after the stirring assembly 20 completes the stirring operation.

[0047] Specifically, the lifting device 40 comprises a driving member 41 and a driving frame 42, wherein the driving member 41 is arranged to be vertically drivable to drive the driving frame 42. The driving unit 21 of the stirring assembly 20 is arranged at the other end of the driving frame 42 away from the driving member 41. The agent storage 321 of the agent feeding member 32 is connected to the driving frame 42. The agent feeding member 323 is connected to the driving frame 42.

[0048] It is understood that the driving member 41 is started to drive the driving frame 42 to move vertically, so that the stirring assembly 20 as a whole moves vertically along with the driving frame 42.

[0049] Therefore, after the stirring assembly 20 completes the stirring operation, the lifting device 40 can be driven to drive the stirring assembly 20 as a whole to move vertically away from the container body 10, so that the output shaft 22 and the stirring member 23 of the stirring assembly 20 are exposed, thereby facilitating the cleaning and replacement of the staff.

[0050] Preferably, the gas storage 311 of the gas feeding member 31 is also connected to the other end of the driving frame 42 away from the driving member 41 and adjacent to the driving unit 21.

[0051] In one embodiment, the driving member 41 is implemented as a hydraulic cylinder, and the belt carrier 42 is connected to the telescopic end of the hydraulic cylinder, so that when the hydraulic cylinder is started to make the telescopic end extend or retract, the belt carrier 42 is driven to move vertically, so that the whole driving and stirring assembly 20 can move close to or away from the container body 10.

[0052] It is worth mentioning that the driving member 41 can also be provided as a lifting device such as a chain wheel, so that the belt carrier 42 can be driven to complete vertical movement.

The belt carrier 42 is connected to the moving table 4123, and the driving element 411 is connected to the moving frame 4124, so that when the driving element 411 rotates the screw rod 4122, the moving table 4123 moves in a direction parallel to the extending direction of the guide rail 4121, so that the belt carrier 42 can move close to or away from the container body 10, so that the whole driving and stirring assembly 20 can move close to or away from the container body 10 correspondingly by following the movement of the belt carrier 42.

[0055] Preferably, the driving element 411 is implemented as an electric motor.
