Description

Technical Field

[0001] The utility model relates to the technical field of on-line weighing of anode carbon blocks, and more particularly to an on-line weighing device for anode carbon blocks. Background Art

[0002] During the anode casting process, due to the inability to accurately control the weight of the carbon blocks, there is often a certain weight difference between the anode carbon blocks, resulting in uneven thickness of the same group of anodes during the electrolysis process as the electrolysis cycle progresses. This leads to premature replacement of the residual anodes with still usable value, causing waste, and even melting of the steel claws and an increase in the iron content of the electrolytic cell, thus affecting the stability of the process control of the entire electrolytic cell.

[0003] In the prior art, a lifting weighing mechanism is usually adopted to weigh and control the casting liquid during the anode casting stage. For example, in the patent with the publication number CN208495788U, a tundish driving and weighing structure for anode plate casting is disclosed. Specifically, it uses a weighing device to detect the weight of the liquid in the tundish in real time.

[0004] However, when regulating the weight of the anode carbon blocks by weighing and controlling the casting liquid during the casting stage, there are local temperature differences caused by multiple castings during the regulation period, resulting in uneven quality of the cast carbon blocks. During the electrolysis process, there are still uneven thicknesses and even fractures.

[0005] Based on the above description, there is an urgent need for an on-line weighing device that can accurately control the weight of the anode carbon blocks put into electrolysis. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an on-line weighing device for anode carbon blocks, aiming to solve the technical problems that in the prior art, weighing during the anode casting stage still cannot accurately control the weight of each anode during the anode use stage, which is likely to cause uneven electrolysis and fractures.

Specific embodiments

[0023] Embodiment 1

[0024] Please refer to Figures 1 to 3 , the present utility model provides the following technical solutions: An on-line weighing device for anode carbon blocks is applicable to the situation of accurately weighing anode carbon blocks on-line and screening them.

[0025] Specifically, as Figures 1 to 3 shown, an on-line weighing device for anode carbon blocks includes a pair of first conveying mechanisms 1, a first induction module 2, a lifting and weighing mechanism 3, and a transfer mechanism 4; the lifting and weighing mechanism 3 is arranged between the pair of first conveying mechanisms 1; the first induction module 2 is mounted on the top side of the first conveying mechanism 1 through a frame 8; the first induction module 2 is electrically connected to the lifting and weighing mechanism 3 through a control module 5; the control module 5 is electrically connected to the first conveying mechanism 1 and the transfer mechanism 4 in sequence.

[0026] In this embodiment, the first conveying mechanism 1 is a commonly used conveyor in the art, and specifically, a chain conveyor or a belt conveyor can be adopted. By using a pair of first conveying mechanisms 1 to support both ends of the anode carbon block, the anode carbon block is conveyed. Further, the lifting and weighing mechanism 3 is arranged at one end of the first conveying mechanism 1 and between the pair of first conveying mechanisms 1, which is convenient for installing the lifting and weighing mechanism 2 to lift and weigh the anode carbon block on the top of the first conveying mechanism 1. When the anode carbon block is conveyed to one side of the first induction module 2 (first photoelectric sensor), the first induction module 2 transmits an electrical signal to the control module 5 (single-chip microcomputer or PLC controller), and then the control module 5 controls the first conveying mechanism 1 to stop immediately, and then starts the lifting and weighing device 3 (second servo motor, multiple lifting rods connected to the first servo motor, and electronic scale) to weigh. For the anode carbon blocks that do not meet the preset weight range, the control module 5 controls the first servo motor to drive the transfer mechanism 4 to push the unqualified anode carbon blocks out of the first conveying mechanism 1.

[0027] In this embodiment, the lifting and weighing mechanism 3 is electrically connected to the electric lifting rod through the control module 5.

[0028] Specifically, as Figure 1 and Figure 2 shown, the transfer mechanism 4 includes a telescopic component 41, a guiding component 42, and a second conveying mechanism 43. The telescopic component 41 is horizontally arranged on the top of the first conveying mechanism 1 and extends towards the second conveying mechanism 43. The second conveying mechanism 43 is arranged at one side end of the first conveying mechanism 1 away from the first induction module 2. The guiding component 42 is arranged between the first conveying mechanism 1 and the second conveying mechanism 43.

[0029] In this embodiment, the telescopic component 41 includes multiple electric telescopic crossbars and a push plate. One end of the electric telescopic crossbar is connected to the frame 8. The other end of the electric telescopic crossbar extends towards the top of the first conveying mechanism 1 and is connected to the push plate. Among them, the second servo motor drives the electric telescopic crossbar to expand and contract.

[0030] Specifically, as Figures 1 to 3 shown, the guiding component 42 includes a frame, multiple rollers, multiple electric lifting rods, and a base. Multiple rollers are rotatably connected to the frame. The first conveying mechanism 1 and the second conveying mechanism 43 are both parallel to the rollers. The frame is connected to the base through multiple electric lifting rods.

[0031] In this embodiment, the electric lifting rod is driven by a third servo motor. By driving the electric lifting rod with the third servo motor, when there are unqualified anode carbon blocks, the telescopic component 41 expands and contracts to guide the unqualified anode carbon blocks through the rollers to the second conveying mechanism 43 (the same as the first conveying mechanism 1, which is a commonly used conveyor in the art) for separation.

[0032] Specifically, asFigures 1 to 3 As shown in the figure, a second induction module 6 is provided on the side of the second transfer mechanism 43 away from the guiding assembly 42; the second induction module 6 is electrically connected to the electric telescopic cross bar through the control module 5.

[0033] In this embodiment, the second induction module 6 is a photoelectric sensor, which transmits an electrical signal to the control module 5, thereby real-time sensing the position of the anode carbon block moving towards the second transfer mechanism 43, and controlling the telescopic movement of the electric telescopic cross bar through the control module 5 to prevent the anode carbon block from slipping; after the anode carbon block moves to an appropriate position on the second transfer mechanism 43, the second induction module 6 transmits an electrical signal to the control module 6, and the second transfer mechanism 43 is controlled to continue conveying through the control module 5.

[0034] Specifically, as Figures 1 to 3 shown in the figure, the frame body 8 is provided with an extension plate; a pair of marking devices 7 are provided on a wall surface of the extension plate close to the first transfer mechanism 1; the weighing mechanism 3 is electrically connected to the pair of marking devices 7 through the control module 5.

[0035] In this embodiment, the marking device 7 includes an alarm lamp and a marker (laser marker or paint marker); the weighing mechanism 3 weighs and transmits an electrical signal to the control module 5, and when an overweight (first marking device) or underweight (second marking device) anode carbon block appears, it is warned by the alarm lamp and corresponding marking is carried out by the marker.

[0036] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
