Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell busbar cleaning technology, and more specifically to an automatic cleaning device for electrolytic cell busbars. Background Technology

[0002] To adapt to the working environment of high molten salt, high current, strong magnetic field and high dust in aluminum electrolysis workshops, especially with the emergence of large prebaked electrolytic cells, the requirements for multi-functional aluminum electrolysis units are also getting higher and higher. It is necessary to combine many single-function machines into a multi-functional and multi-purpose machine to improve efficiency, and change the filling or grabbing of filler, insulation material and alumina from open to closed to improve the workshop working environment. This has led to the promotion of the use of such multi-functional machines, namely multi-functional overhead crane moving parts.

[0003] However, during the electrolysis process, excessive dust may accumulate on the busbar. After the electrode replacement operation by the moving part of the multi-functional overhead crane, the surface of the horizontal busbar at the electrode replacement point is manually cleaned by connecting the air duct from the ground air source. The personnel need to face the molten pool after the residual electrode is pulled out. The temperature of the molten pool is above 900℃. On the one hand, there is a great safety risk for personnel to get close to the molten pool. On the other hand, in order to ensure safety, the manual surface cleaning distance from the molten pool cannot be too close. As a result, the surface cleaning of the contact surface between the horizontal busbar and the anode group guide rod is not ideal, which can easily cause poor conductivity of the new electrode after the electrode replacement, resulting in fluctuations in the voltage of the electrolytic cell and affecting the stability of the electrolytic cell.

The device also includes a connecting plate, a blowing mechanism, and an auxiliary dust blowing mechanism. The connecting plate is located below the lifting component via a rotating assembly. The blowing mechanism is located on the connecting plate for blowing away dust from the top of the busbar body. The auxiliary dust blowing mechanism is located below the connecting plate for blowing away dust from the portion of the busbar body obscured by the anode guide rod.

[0008] Furthermore, the rotating assembly includes a dust cover, a first motor, and a first rotating shaft.

Another end of the first rotating shaft is coaxially fixedly connected to the output end of the first motor.

[0009] Furthermore, the purging mechanism includes an air compressor, an air outlet pipe, a fixed plate, a main air duct, and multiple main air nozzles.

The top end of the fixed plate is fixedly connected to the bottom end of the connecting plate. The top end of the main air duct is fixedly connected to the bottom end of the fixed plate. The middle part of the outer side wall of the main air duct is connected to the other end of the air outlet pipe. One end of each of the multiple main air nozzles is connected to the bottom end of the main air duct.

[0010] As a further embodiment of this solution, the auxiliary dust blowing mechanism includes a telescopic tube, a secondary air duct, multiple secondary air nozzles, and an adjustment component. One end of the telescopic tube is connected to the other end of the outer wall of the main air duct, one end of the secondary air duct is connected to the other end of the telescopic tube, and one end of each of the multiple secondary air nozzles is connected to the bottom end of the secondary air duct. The adjustment component is disposed on the fixed plate and the secondary air duct, and is used to move the secondary air duct to the top of the busbar body and blow dust left and right.

[0011] As a further embodiment of this solution, the adjustment assembly includes an electric telescopic rod, a connecting seat, a semi-toothed ring, a gear, and a second motor. One end of the electric telescopic rod is fixedly connected to one end of the fixed plate, and one end of the connecting seat is fixedly connected to the other end of the electric telescopic rod.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] Please see Figures 1 to 5 An automatic cleaning device for the busbar of an electrolytic cell includes a busbar body 1 and a crane moving part 2. Multiple clamps 3 are fixedly connected to the busbar body 1 for fixing and clamping the anode guide rod 4. The crane moving part 2 is located above the busbar body 1. A lifting component 5 is fixedly connected to the bottom of the crane moving part 2. The crane moving part 2 drives the lifting component 5 to move, thereby driving the blowing mechanism and the auxiliary dust blowing mechanism to move to one side of the busbar body 1 and the anode guide rod 4. The device also includes a connecting plate 6, a blowing mechanism, and an auxiliary dust blowing mechanism.

[0028] It should be added that the bottom end of the first rotating shaft 9 is rotatably connected to a clamping member 26, which is used to clamp the two anode guide rods 4 for electrode switching.

[0029] like Figure 2 As shown, the connecting plate 6 is set on the lower side of the lifting component 5 through a rotating assembly. The rotating assembly includes a dust cover 7, a first motor 8, and a first rotating shaft 9. The top of the dust cover 7 is fixedly connected to the bottom of the lifting component 5. The first motor 8 is installed inside the dust cover 7. One end of the first rotating shaft 9 is coaxially rotatably connected to the bottom of the dust cover 7. One end of the first rotating shaft 9 is coaxially fixedly connected to the output end of the first motor 8. By starting the first motor 8, the output end of the first motor 8 rotates, driving the first rotating shaft 9 to rotate, and the first rotating shaft 9 drives the connecting plate 6 to rotate.

[0030] like Figure 2 and Figure 4As shown, the purging mechanism is mounted on the connecting plate 6 and is used to purge dust from the top of the busbar body 1. The purging mechanism includes an air compressor 10, an air outlet pipe 11, a fixing plate 13, a main air duct 14, and multiple main air nozzles 15. The air compressor 10 is mounted on the connecting plate 6. One end of the air outlet pipe 11 is connected to the output end of the air compressor 10 via a solenoid valve 12. The solenoid valve 12 is installed between the air outlet pipe 11 and the air compressor 10. The top end of the fixing plate 13 is fixedly connected to the bottom end of the connecting plate 6. The top end of the main air duct 14 is fixedly connected to the bottom end of the fixing plate 13. The middle part of the outer side wall of the main air duct 14 is connected to the other end of the air outlet pipe 11. One end of each of the main air nozzles 15 is connected to the bottom end of the main air duct 14. The other end of the main air nozzles 15 is inclined and faces the busbar body 1. After the clamping member 26 is moved above the corresponding anode guide rod 4 by the crane moving part 2, the clamping member 26, the blowing mechanism and the auxiliary dust blowing mechanism are driven to move downward by the lifting part 5. When the clamping member 26 is in a suitable clamping working position, the blowing mechanism is on one side of the busbar body 1. When the air compressor 10 is started and the solenoid valve 12 is started, the air moves from the air outlet pipe 11 into the main air duct 14 and is transferred to the multiple main air nozzles 15 to blow the top of the busbar body 1.

[0031] like Figure 3 , Figure 4 and Figure 5As shown, the auxiliary dust blowing mechanism is located below the connecting plate 6 and is used to blow away dust from the part of the busbar body 1 that is blocked by the anode guide rod 4. The auxiliary dust blowing mechanism includes a telescopic pipe 16, a secondary air duct 17, multiple secondary air nozzles 18, and an adjustment assembly. One end of the telescopic pipe 16 is connected to the other end of the outer wall of the main air duct 14, one end of the secondary air duct 17 is connected to the other end of the telescopic pipe 16, and one end of each of the multiple secondary air nozzles 18 is connected to the bottom end of the secondary air duct 17. The adjustment assembly is located on the fixed plate 13 and the secondary air duct 17 and is used to move the secondary air duct 17. The device moves to the top of the busbar body 1 and blows away dust from left and right. The adjustment assembly includes an electric telescopic rod 19, a connecting seat 20, a semi-toothed ring 22, a gear 23, and a second motor 25. One end of the electric telescopic rod 19 is fixedly connected to one end of the fixed plate 13, and one end of the connecting seat 20 is fixedly connected to the other end of the electric telescopic rod 19. A protrusion 21 is provided at the bottom end of the connecting seat 20, and the protrusion 21 is rotatably connected to the other end of the auxiliary air duct 17. The semi-toothed ring 22 is fitted onto the outer wall of the auxiliary air duct 17 and is coaxially fixedly connected to the auxiliary air duct 17. The base 20 has a groove that engages with the gear 23. The gear 23 rotates with the inner wall of the groove via a second rotating shaft 24. The second motor 25 is embedded in the connecting base 20, and its output end is coaxially and fixedly connected to the gear 23. After the lifting component 5 drives the auxiliary dust blowing mechanism to one side above the busbar body 1, it moves the connecting base 20 toward the busbar body 1 by activating the electric telescopic rod 19. The connecting base 20 moves the protrusion 21 and the auxiliary air duct 17, and the auxiliary air duct 17 moves the other end of the telescopic rod. When the auxiliary air nozzles 18 are directly above the busbar body 1, the second motor 25 is started. The output end of the second motor 25 rotates, which drives the second shaft 24 to rotate. The second shaft 24 drives the gear 23 to rotate, the gear 23 drives the half-tooth ring 22 to rotate, and the half-tooth ring 22 drives the auxiliary air duct 17 to rotate. The rotation angle is between 0 degrees and 60 degrees. This can blow away the dust on the busbar body 1 and hidden behind the anode guide rod 4, that is, the dust that is "hidden" in the corner and not blown away by the main air nozzle 15.

[0032] It should be further explained that the first motor 8 and the second motor 25 in this embodiment are both commercially available conventional devices known to those skilled in the art. The model can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function. For those skilled in the art, the setting method, installation method and electrical connection method can be debugged and operated according to the requirements of the instruction manual, and will not be described in detail here. The first motor 8 and the second motor 25 are both equipped with matching control switches. The installation position of the control switches can be selected according to the actual use requirements to facilitate the operation and control of the operator. At the same time, the motors need to be connected to the forward and reverse circuit before use for forward and reverse operation. As for the forward and reverse use of the motor, according to the patent disclosed in patent number CN109889124A, the forward and reverse operation of the motor is a well-known technology to those skilled in the art, and the technology is very mature and can be implemented.

[0033] Working Principle: When cleaning the dust accumulated on the electrolytic cell busbar, the automatic cleaning device utilizes the overhead crane moving part 2, lifting component 5, and clamping component 26 in conjunction with each other during the electrode switching process. The overhead crane moving part 2 moves the clamping component 26 above the corresponding anode guide rod 4. Then, the lifting component 5 drives the clamping component 26, the blowing mechanism, and the auxiliary dust blowing mechanism downwards. When the clamping component 26 is in the appropriate clamping position, the blowing mechanism is positioned on one side of the busbar body 1. By starting the air compressor 10 and activating the solenoid valve 12, air moves from the outlet pipe 11 into the main air pipe 14 and is transferred to multiple main air nozzles 15, thus blowing the top of the busbar body 1. This removes some of the dust accumulated on the busbar body 1 and the clamping component 3. Simultaneously, the electric telescopic rod 19 is activated... The moving connecting seat 20 moves toward the busbar body 1. The connecting seat 20 drives the protrusion 21 and the auxiliary air duct 17 to move. The auxiliary air duct 17 drives the other end of the telescopic rod to move and stretch it. When multiple auxiliary air nozzles 18 are directly above the busbar body 1, the second motor 25 is started. The output end of the second motor 25 rotates and drives the second rotating shaft 24 to rotate. The second rotating shaft 24 drives the gear 23 to rotate. The gear 23 drives the half-tooth ring 22 to rotate. The half-tooth ring 22 drives the auxiliary air duct 17 to rotate. The rotation angle is between 0 degrees and 60 degrees. This can blow away the dust on the busbar body 1 and hidden behind the anode guide rod 4. That is, it can blow away the dust that is "hidden" in the corner and not blown away by the main air nozzle 15. This can blow away most of the dust accumulated on the busbar body 1, avoid fluctuations in the electrolytic cell voltage, and improve the stability of the electrolytic cell.

[0034] After the dust is blown away, the electric telescopic rod 19 and the lifting component 5 drive the connecting seat 20 and the dust cover 7 back to their initial positions in sequence. By starting the first motor 8, the output end of the first motor 8 rotates, which drives the first rotating shaft 9 to rotate. The first rotating shaft 9 drives the connecting plate 6 to rotate. The first motor 8 drives the connecting plate 6 to rotate 90 degrees, so that the connecting plate 6 drives the blowing mechanism and the auxiliary dust blowing mechanism to "flip" at an angle. In conjunction with the crane moving part 2, dust blowing can be carried out when the electrodes on both sides of multiple electrolytic cells are changed.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
