Description

Technical Field

[0002] In the electrolytic aluminum production process, the anode carbon blocks of prebaked anodes are gradually consumed as production progresses. The portion of the prebaked anode that remains at the end of the electrolysis cycle is called the residual anode.

The remaining anode carbon blocks can be returned to carbon production after crushing. The separated anode rod can be cast and connected to a new anode carbon block to form a new prebaked anode. During the casting and connection process of the anode rod and the new anode carbon block, it is usually necessary for operators to manually take molten iron from the smelting furnace and transfer it to the casting station. This casting and connection operation poses certain safety hazards, and the amount of molten iron taken is difficult to control, which can easily affect the casting quality of the new prebaked anode.

[0053] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0054] It should be noted that during the electrolytic aluminum production process, the anode carbon blocks of the prebaked anode are gradually consumed as production progresses. The portion of the prebaked anode that remains at the end of the electrolysis cycle is called the residual anode. The electrolyte on the surface of the residual anode can be returned to electrolysis after cleaning and crushing. The remaining anode carbon blocks can be returned to carbon production after crushing. The separated anode rod can be cast and connected with new anode carbon blocks to form a new prebaked anode. However, during the casting and connection process of the anode rod and the new anode carbon block, operators usually need to manually take molten iron from the smelting furnace and transfer it to the casting station. This casting and connection operation poses certain safety hazards. Furthermore, the amount of molten iron taken is usually manually controlled by the operators, and the accuracy of the amount taken is difficult to guarantee, which can easily affect the casting quality of the new prebaked anode.

[0055] In view of this, such as Figures 1 to 3 As shown, a first aspect of the present disclosure provides a prebaked anode casting system 10 for aluminum electrolysis, comprising: a casting device 100 having a holding tank 101 and a drain outlet 102, the holding tank 101 being used to hold molten iron, and the drain outlet 102 being connected to the holding tank 101 and used to discharge the molten iron from the holding tank 101; and a supporting device 200 disposed on one side of the casting device 100, the supporting device 200 being used to place the prebaked anode 10' to be cast, and the casting device 100 being used to pour... The prebaked anode 10' to be cast is poured with molten iron; a receiving device 300 is used to hold the molten iron output from the intermediate frequency furnace and to add molten iron to the holding tank 101; a transfer device 400 is used to move the receiving device 300 between the casting device 100 and the intermediate frequency furnace; a weighing device 500 is used to obtain the weight information of the molten iron contained in the receiving device 300.

[0056] The prebaked anode casting system 10 for aluminum electrolysis provided in this embodiment includes the aforementioned casting device 100, bearing device 200, receiving device 300, transfer device 400, and weighing device 500. The aforementioned containing device 300 is mounted on the aforementioned transfer device 400. In practical applications, the containing device 300 can be used to hold molten iron output from the intermediate frequency furnace and to add molten iron to the holding tank 101 of the aforementioned casting device 100. The transfer device 400 can move the containing device 300 between the intermediate frequency furnace and the aforementioned casting device 100, thereby facilitating the containing device 300 to perform the aforementioned operation of connecting or adding molten iron and enabling the transfer of molten iron, reducing manual intervention in the transfer operation and improving the safety of the production process. The aforementioned weighing device 500 is mounted on the containing device 300 and can be used to obtain the weight information of the molten iron contained in the containing device 300, thereby facilitating the operator to understand the amount of molten iron stored in the containing device 300 during operation and assisting the operator in determining the amount of molten iron connected by the containing device 300 when connecting molten iron output from the intermediate frequency furnace. The weight of the molten iron, i.e., the amount of molten iron to be used, helps to improve the accuracy of the amount of molten iron to be used, thus ensuring the quality of the prebaked anode casting. The aforementioned supporting device 200 is set on one side of the aforementioned casting device 100. In practical applications, the aforementioned supporting device 200 can be used to place the prebaked anode 10' to be cast. The aforementioned casting device 100 can discharge the molten iron in the holding tank 101 through the drain port 102 and use it to pour the molten iron into the aforementioned prebaked anode 10' to be cast. 0' Pour molten iron into the anode guide rod 11' and anode carbon block 12' of the prebaked anode 10' to be cast into the molten iron ...

[0057] It is understood that, in practical applications, the aforementioned casting device 100 can be arranged within the prebaked anode processing workshop, for example, at the casting station within the prebaked anode processing workshop. The aforementioned casting device 100 and the aforementioned intermediate frequency furnace can be located in different workshops or at different stations within the same workshop. Correspondingly, the aforementioned transfer device 400 may include, but is not limited to, an automated guided vehicle (AGV). The AGV can have pre-stored running trajectory coordinates, and during operation, the AGV can automatically move between the aforementioned casting device 100 and the intermediate frequency furnace according to the aforementioned running trajectory coordinates. The aforementioned receiving device 300 can be mounted on the AGV and move along with it. The aforementioned running trajectory coordinates can be set according to the actual layout of the production environment, and are not subject to further limitations here.

[0058] For example, the aforementioned automated guided vehicle is configured to move toward the aforementioned medium-frequency furnace in response to a liquid retrieval command until the receiving device 300 corresponds to the molten iron output end of the medium-frequency furnace, and to move toward the aforementioned pouring device 100 in response to a transfer command until the holding tank 101 is within the pouring range of the receiving device 300.

[0059] It is understood that, in practical applications, the aforementioned supporting device 200 may be fixedly installed on one side of the aforementioned casting device 100, or it may be movably arranged relative to the casting device 100. When the supporting device 200 is movably arranged relative to the casting device 100, the range of motion of the supporting device 200 includes a casting position. When the supporting device 200 is in the aforementioned casting position, it is located on one side of the aforementioned casting device 100 and is suitable for receiving the molten iron poured out by the casting device 100 from the prebaked anode 10' placed on it. For example, the aforementioned prebaked anode processing workshop may be equipped with a conveyor, and the number of the aforementioned supporting devices 200 may be multiple, with multiple supporting devices 200 mounted on the conveyor and driven by the conveyor. During the operation of the conveyor, the carrier device 200 can pass through the alignment and mold closing position, the casting waiting position, and the aforementioned casting position in one go. When the carrier device 200 is located at the aforementioned alignment and mold closing position, the carrier device 200 is used to load the anode guide rod 11' to be cast. The carrier device 200 with the prebaked anode 10' to be cast can be further moved to the aforementioned casting waiting position under the drive of the aforementioned conveyor, so that it can be moved to the aforementioned casting position after the previous batch of prebaked anodes 10' to be cast is completed, thereby improving the processing continuity of the prebaked anode.

[0060] It is understood that the prebaked anode 10' to be cast may include an anode guide rod 11' and an anode carbon block 12'. The top of the anode carbon block 12' is provided with a carbon bowl structure. The steel claw part of the anode guide rod 11' is provided in the aforementioned carbon bowl structure. The aforementioned casting device 100 can perform the action of pouring molten iron into the aforementioned carbon bowl, thereby realizing the casting connection between the anode guide rod 11' and the anode carbon block 12'.

[0061] In some feasible examples, the support device 200 can be a trough-shaped structure for placing the aforementioned anode carbon block 12'. Exemplarily, the support device 200 can be made of a heat-resistant material.

[0062] In some feasible examples, the aforementioned weighing device 500 may include a weight sensor disposed on the aforementioned container 300 and used to acquire weight information of the molten iron containing phosphorus in the container 300. It is understood that the weight sensor may be disposed on the outer bottom wall of the container 300 to facilitate weight monitoring and reduce the impact of the molten iron on the operation of the weight sensor.

[0063] In some feasible examples, the aforementioned weighing device 500 may also include a warning component. This warning component is signal-connected to the aforementioned weight sensor and is used to generate a warning message when the aforementioned weight reaches a preset weight. The preset weight may be determined based on the weight of molten iron required for casting the prebaked anode 10'. For example, the preset weight may be equal to the weight of molten iron required for casting the prebaked anode 10'. Thus, the prebaked anode casting system 10 for aluminum electrolysis can use the warning component to remind operators to close the molten iron output end of the intermediate frequency furnace when the weight of molten iron stored in the containing device 300 reaches the casting requirement. This facilitates the quantitative use of molten iron, providing a more reliable guarantee for the accuracy of the molten iron usage, and thus helps ensure the casting quality of the prebaked anode. It is understood that the aforementioned warning component may include, but is not limited to, components suitable for outputting acoustic information such as buzzers and loudspeakers, or components suitable for outputting optical information such as warning lights and displays. Accordingly, the aforementioned warning information may be acoustic or optical information.

[0064] In some feasible examples, the aforementioned weighing device 500 may further include a signal transmitting component. This component is signal-connected to the weight sensor and the intermediate frequency furnace, and is used to send a shutdown command to the intermediate frequency furnace when the weight reaches a preset weight. The intermediate frequency furnace is configured to shut down the molten iron output in response to the shutdown command. Thus, the prebaked anode casting system 10 for aluminum electrolysis can automatically shut down the molten iron output of the intermediate frequency furnace using the signal transmitting component when the weight of the molten iron stored in the containing device 300 reaches the casting requirements. This facilitates the quantitative use of molten iron, providing a more reliable guarantee for the accuracy of the molten iron usage, thereby ensuring the casting quality of the prebaked anode and further reducing the workload and injury risk for operators. It is understood that the signal transmitting component can be wired or wirelessly connected to the intermediate frequency furnace.

[0065] In some feasible examples, the aforementioned weighing device 500 may include both the aforementioned warning component and the aforementioned signal transmitting component.

[0066] like Figure 2 and Figure 3 As shown, in some examples, the pouring device 100 includes: a first tank portion 110 having a drain side 103 located between the top and bottom ends of the first tank portion 110, a drain outlet 102 opening on the drain side 103, a holding tank 101 opening on the top end of the first tank portion 110, and a support device 200 arranged corresponding to the drain side 103; a first drive portion 120 connected to the first tank portion 110, the first drive portion 120 being used to drive the first tank portion 110 to rotate, thereby adjusting the angle between the drain side 103 and the horizontal plane.

[0067] In this technical solution, the casting device 100 may include the aforementioned first tank portion 110 and the aforementioned first drive portion 120. Based on the aforementioned configuration, the opening of the holding tank 101 can be located at the top of the first tank body 110, thereby facilitating the access of the molten iron output from the receiving device 300 and improving the convenience of the receiving device 300 when adding molten iron to the holding tank 101. The drain port 102 is located on the aforementioned drain side 103, and the first driving unit 120 can drive the first tank body 110 to rotate, so that the angle between the drain side 103 and the horizontal plane changes. This allows for the adjustment of the distance between the molten iron liquid level in the holding tank 101 and the drain port 102, so that the molten iron can be stably stored in the holding tank 101, or that the molten iron can be poured out through the aforementioned drain port 102. This improves the controllability of the pouring action of the casting device 100 in pouring molten iron, enhances the ease of use of the casting device 100, and helps to further reduce the amount of manual work when pouring molten iron into the prebaked anode 10' to be cast, thereby enhancing the safety of the casting operation.

[0068] It is understood that the aforementioned drain side 103 may be a lateral tank wall extending between the top and bottom ends of the first tank body 110.

[0069] In some feasible examples, the first tank portion 110 may include a first outer shell and a first tank-shaped component. The first tank-shaped component has the aforementioned holding tank 101 and is disposed within the aforementioned first outer shell. The aforementioned drain port 102 penetrates the aforementioned first outer shell and the aforementioned first tank-shaped component. The aforementioned first outer shell is made of steel, and the aforementioned first tank-shaped component is made of heat-resistant and heat-insulating material. Exemplarily, the aforementioned first tank-shaped component includes a first insulation board, a first interlayer, and a first graphite crucible. The first graphite crucible defines the aforementioned holding tank 101. The first insulation board covers the outer wall of the first graphite crucible. The first interlayer is disposed between the aforementioned first graphite crucible and the first insulation board. The first insulation board may be, but is not limited to, a nano-insulation board, and the first interlayer may be made of, but is not limited to, a castable material.

[0070] In some feasible examples, the aforementioned drain port 102 can be arranged close to the top of the first tank body 110, which is beneficial to increase the effective volume of the holding tank 101 when the volume of the first tank body 110 is limited, which is beneficial to the holding tank 101 to hold more molten iron, and to the molten iron in the holding tank 101 to be poured out during the rotation of the first tank body 110.

[0071] like Figure 1 and Figure 2 As shown, in some examples, the first drive unit 120 includes: a support leg 121, one end of which is hinged to the bottom end of the first tank part 110; a drive cylinder 122, which is a telescopic structure, one end of which is hinged to the bottom end of the first tank part 110 in the telescopic direction; wherein, the angle between the drain side 103 and the horizontal plane is adapted to change with the length of the drive cylinder 122 in the telescopic direction.

[0072] In this technical solution, the first driving unit 120 may include the aforementioned support leg 121 and the aforementioned driving cylinder 122. Based on the aforementioned configuration, both the support leg 121 and the driving cylinder 122 can rotate relative to the first tank body 110. In practical applications, the end of the support leg 121 away from the first tank body 110 and the other end of the driving cylinder 122 in the extension and retraction direction can be supported on the ground or a mounting platform, thereby achieving support and fixation of the first tank body 110, which is beneficial for the stable placement of the first tank body 110 and improves the safety of the pouring device 100. When the driving cylinder 122 undergoes extension and retraction, the angle between the aforementioned drain side 103 and the horizontal plane can change accordingly, thereby enabling the adjustment of the distance between the liquid level of the molten iron in the holding tank 101 and the drain port 102, so that the molten iron can be stably stored in the holding tank 101, or the molten iron can be poured out through the aforementioned drain port 102.

[0073] It is understandable that the aforementioned horizontal plane is a reference plane perpendicular to the direction of gravity.

[0074] Understandably, in practical applications, the drive cylinder 122 can be connected to an air source, which supplies pressurized gas to the drive cylinder 122 to extend and retract. The pressurized gas can be air, which helps improve the cleanliness of the drive cylinder 122.

[0075] It is understandable that the outrigger 121 can be rod-shaped, and the axial direction of the outrigger 121 and the extension and retraction direction of the drive cylinder 122 can both be arranged perpendicular to the ground or the mounting platform, which is beneficial for the outrigger 121 and the drive cylinder 122 to stably support the first groove part 110.

[0076] For example, both the support leg 121 and the drive cylinder 122 are adapted to rotate relative to the first tank portion 110 about a first direction. The end of the support leg 121 that is hinged to the first tank portion 110 and the end of the drive cylinder 122 that is hinged to the first tank portion 110 are arranged at intervals along a second direction. The first direction is perpendicular to the second direction, and the second direction intersects the extension direction of the aforementioned drain side 103. Thus, when the support leg 121 and the drive cylinder 122 are supported on the ground or a mounting platform, the angle between the drain side 103 and the horizontal plane can change accordingly when the length of the drive cylinder 122 in the extension direction changes. The number of the aforementioned support leg 121 and drive cylinder 122 can be multiple, with multiple support legs 121 arranged at intervals along the aforementioned first direction and multiple drive cylinders 122 arranged at intervals along the aforementioned first direction.

[0077] like Figures 1 to 3As shown, in some examples, the pouring device 100 further includes: a pouring section 130 disposed in the first tank section 110, the pouring section 130 protruding from the drain side 103 in a direction away from the holding tank 101, and the pouring section 130 having a guide groove 104 communicating with the drain port 102.

[0078] In this technical solution, the casting device 100 may further include the aforementioned gate section 130. Based on the aforementioned configuration, the casting device 100 can use the gate section 130 to guide the flow direction of the molten iron flowing out of the drain port 102, which can prevent the molten iron from adhering to the aforementioned drain side 103. This helps to prevent the molten iron from flowing along the drain side 103 after flowing out of the drain port 102, reducing the probability of the molten iron splashing onto the production site. This further improves the safety and cleanliness of the casting process, and helps to achieve stable control over the pouring direction of the molten iron, thereby improving the casting quality.

[0079] like Figure 3 As shown, in some examples, there are multiple drain ports 102, and the distance between the multiple drain ports 102 and the bottom wall of the holding tank 101 is the same along the depth direction of the holding tank 101.

[0080] In this technical solution, there can be multiple drain ports 102, and the multiple drain ports 102 are positioned in the same direction along the depth of the holding tank 101. Based on the aforementioned configuration, the casting device 100 can discharge molten iron from the phosphorus through multiple channels. In practical applications, the multiple drain ports 102 can be arranged one-to-one with the multiple carbon bowls on the anode carbon block 12', which facilitates the casting device 100 to simultaneously pour molten iron from the phosphorus into multiple carbon bowls, thereby improving casting efficiency. Furthermore, by setting the distance between the multiple drain ports 102 and the bottom wall of the holding tank 101 to be the same along the depth direction of the holding tank 101, the consistency of the flow rate and the synchronicity of the pouring of the multiple drain ports 102 can be improved, which in turn helps to improve the consistency of the pouring amount to the multiple carbon bowls and further ensures the casting quality.

[0081] like Figure 1 As shown, in some examples, the receiving device 300 includes: a second tank portion 310 forming an open receiving tank for holding molten iron output from an intermediate frequency furnace; a cover portion 320 detachably disposed on the second tank portion 310 for opening or covering the open of the receiving tank; and a cover driving portion 330 connected to the cover portion 320 for driving the cover portion 320 to move so that the cover portion 320 opens or covers the open of the receiving tank.

[0082] In this technical solution, the receiving device 300 may include the aforementioned second tank body 310, cover body 320, and cover body driving unit 330. Based on the aforementioned configuration, the receiving device 300 can open and close the opening of the receiving tank by using the cover body driving unit 330 to drive the cover body 320 to move. Thus, when the receiving device 300 needs to perform the entry and exit of molten iron, the cover body driving unit 330 can drive the cover body 320 to open the opening of the aforementioned receiving tank, so that the molten iron can enter and exit the second tank body 310 through the opening of the receiving tank. Alternatively, during the transfer process of the receiving device 300, the cover body driving unit 330 can drive the cover body 320 to cover the opening of the receiving tank, thereby ensuring the stability of the environment of the receiving tank and preventing the molten iron from experiencing significant heat loss or oxidation during the transfer process, which is beneficial for ensuring the stable transportation of molten iron.

[0083] It is understood that the specific form of the aforementioned cover driving part 330 can be selected in various ways. It can drive the cover part 320 to move relative to the second groove part 310 so that the cover part 320 opens or covers the opening of the receiving groove. No further limitations are made here.

[0084] In some feasible examples, the second tank portion 310 may include a second outer shell and a second tank-shaped member, the second tank-shaped member having the aforementioned receiving groove and disposed within the aforementioned second outer shell; the aforementioned second outer shell is made of steel, and the aforementioned second tank-shaped member is made of heat-resistant and heat-insulating material.

[0087] It is understandable that the transfer vehicle 410 could be the aforementioned automated guided vehicle.

[0088] It is understandable that the second drive unit 420 can take many forms, as long as it can drive the receiving device 300 to move along the height direction of the transfer vehicle 410. No further restrictions are imposed here.

[0091] like Figure 4 As shown, a control method for a prebaked anode casting system for aluminum electrolysis is provided according to a second aspect of the present disclosure, for use in the prebaked anode casting system 10 for aluminum electrolysis as described in any of the first aspects above, the aforementioned control method comprising:

[0092] Step S101: In response to the liquid taking command, control the transfer device 400 to drive the receiving device 300 to move towards the medium frequency furnace until the receiving device 300 corresponds to the molten iron output end of the medium frequency furnace;

[0093] Specifically, the prebaked anode casting system 10 for aluminum electrolysis can respond to the aforementioned liquid extraction command, and in response to the aforementioned liquid extraction command, the aforementioned transfer device 400 can drive the receiving device 300 to move closer to the medium frequency furnace until the receiving device 300 is arranged correspondingly to the iron output end of the medium frequency furnace, so that the receiving device 300 is ready to receive the phosphorus pig iron output from the medium frequency furnace.

[0094] It is understandable that the aforementioned liquid dispensing command can be issued manually by the operator. For example, if the transfer device 400 includes the aforementioned automated guided vehicle, the control panel of the automated guided vehicle can be equipped with a button area for the aforementioned liquid dispensing command, and the aforementioned liquid dispensing command can be issued by the operator by operating the aforementioned button area.

[0097] Specifically, the weighing device 500 can acquire the weight information of the molten iron containing the container 300. The aforementioned weight information can help operators understand the amount of molten iron stored in the container 300 during operation, and can also help operators determine the weight of the molten iron entering the container 300 when it is connected to the molten iron output from the medium frequency furnace, that is, determine the amount of molten iron to be taken, thereby improving the accuracy of the amount of molten iron to be taken and ensuring the quality of prebaked anode casting.

[0098] It is understood that when the receiving device 300 corresponds to the molten iron output end of the medium frequency furnace, the aforementioned step S102 can be performed, thereby shortening the running time of the weighing device 500 and reducing the amount of data and energy consumption generated during system operation.

[0099] Step S103: If the weight information reaches the preset weight, generate a warning message. The preset weight is determined based on the weight of molten iron required for casting the prebaked anode 10'.

[0100] Specifically, when the weight information obtained by the weighing device 500 reaches the aforementioned preset weight, the prebaked anode casting system 10 for aluminum electrolysis generates the aforementioned warning information to remind the operator to close the molten iron output end of the medium frequency furnace, so as to facilitate the quantitative use of phosphorus pig iron, provide a more reliable guarantee for the accuracy of the amount of phosphorus pig iron used, and thus help to ensure the casting quality of the prebaked anode.

[0101] It is understood that the aforementioned preset weight can be equal to the weight of molten iron required for casting the prebaked anode 10'. The aforementioned weight of molten iron required for casting the prebaked anode 10' can be specifically determined by combining the shape parameters of the carbon bowl structure on the anode carbon block 12' and the number of carbon bowls.

[0110] When the cover 320 opens the accommodating tank, a prompt message is generated or an opening command is sent to the induction furnace. The induction furnace is configured to open the molten iron output end in response to the aforementioned opening command.

[0111] Specifically, when the cover 320 opens the accommodating tank, the prebaked anode casting system 10 for aluminum electrolysis generates the aforementioned prompt information to remind the operator to open the molten iron output end of the intermediate frequency furnace so that the accommodating device 300 can receive the phosphorus pig iron, or the aforementioned opening command can be directly sent to the intermediate frequency furnace to control the intermediate frequency furnace to automatically open the molten iron output end.
