Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection technology, and specifically relates to an online rust removal and cleaning device for anode steel claws for aluminum. Background Art

[0002] In the aluminum electrolysis production process, the electrolytic cell is powered to produce aluminum liquid, which requires positive and negative electrodes and related catalysts. The positive electrode, also known as the anode, is composed of three parts: the anode guide rod, the anode steel claw and the anode carbon block. Figure 1 As shown in the figure, the anode processing is completed in the anode assembly workshop, and the anode steel claw is inserted into the carbon bowl of the anode carbon block, and then connected by iron tree casting. When the anode is used in the electrolytic cell production, with the increase of temperature, the exposed steel claw will be oxidized, and the electrolyte, carbon block residue and dust will adhere to the surface of the steel claw. These impurities are very unfavorable for the casting connection of the anode steel claw, which will increase the contact resistance and energy consumption. In severe cases, it may cause the carbon block and steel claw to separate during the production process, so it is very necessary to clean the surface of the steel claw.

[0003] At present, there are two main automatic cleaning methods for steel claws: shot blasting and chain throwing. Shot blasting is to throw a certain amount of iron sand at the steel claw at high speed, and clean the impurities on the surface of the steel claw through collision and friction. This cleaning method has the best effect, but the iron sand is consumed very quickly and has a high cost, so it is basically no longer used in the industry. Chain throwing cleaning is to use a motor to drive several iron chains to directly hit the steel claw. This cleaning method can clean most of the sticky impurities, but rust and some tightly stuck impurities cannot be cleaned. In this way, the motor speed is high and the cleaning is relatively clean, but the chain is replaced more frequently and the noise is loud; the motor speed is low, it is difficult to clean, and the effect is poor. At present, many people in this field adopt a compromise method, which is to install a set of chain throwing cleaning, but run it at a low speed, observe it manually, and then clean it manually if there are a lot of rust and impurities left.

[0004] The Chinese utility model patent with publication number CN215201315U discloses a device for cleaning anode steel claws, which includes a frame, a conveying catenary and a brushing device; a conveying catenary is arranged above the frame; a brushing device is arranged on the frame; the brushing device includes a wire brush roller and a steel bar brush, and at least two wire brush rollers are rotatably arranged on the frame; the wire brush rollers are symmetrically and evenly distributed on both sides of the conveying catenary; corresponding steel bar brushes are fixed on the frames on both sides of the conveying catenary. The advantages of the utility model are: the utility model has a simple structure, is easy to implement, does not require manual knocking and cleaning, saves time and effort, reduces the work intensity of slag cleaning, improves work efficiency, saves labor costs, and avoids safety hazards; improves the service life of the furnace lining, ensures the quality of aluminum products; protects the on-site working environment; and realizes automatic cleaning. However, the utility model uses a steel bar brush, and when the strength is not well controlled, it is easy to not clean it thoroughly or damage the surface of the steel slag. Utility Model Content

[0027] The pneumatic high-frequency striker 1 is driven by compressed air and includes a cross-cone striking head 1.1. When in action, the cross-cone striking head 1.1 rotates and performs high-frequency striking action. The striking head 1.1 strikes the surface of the anode steel claw 14 at a high frequency to remove rust and other impurities. When the pneumatic high-frequency striker 1 is installed on the fixed beam 2.1 of the horizontal mounting frame 2, the shock absorber 1.2 is used to reduce the impact of vibration on the mounting mechanism. The number of pneumatic high-frequency strikers 1 installed is determined according to the number of claws of the anode steel claw 14, and the pneumatic high-frequency striker 1 is installed in an adjustable manner when installed on the fixed beam 2.1, which can be more fixed according to the anode steel claws 14 of different specifications.

[0028] The horizontal mounting frame 2 is composed of a fixed beam 2.1 and a horizontal telescopic drive mechanism 2.2. By adjusting the position of the fixed beam 2.1 through the horizontal telescopic drive device 2.2, the horizontal mounting frame 2 can complete the horizontal telescopic action of the pneumatic high-frequency striker 1 to ensure effective contact between the striking head 1.1 and the anode steel claw 14.

[0029] The lifting platform 3 is composed of a platform 3.1 and a lifting drive mechanism 3.2. The lifting platform 3 is installed on the equipment frame 9, and the platform is moved up and down by the lifting drive mechanism 3.2. The lifting platform 3 can complete the vertical lifting action of the horizontal installation frame 2 and the pneumatic high-frequency beater 1.

[0030] The fixing fixture 4 is fixed by the equipment frame 9. When the anode steel claw 14 is in place, it holds the anode guide rod 13 to ensure the stability of the anode steel claw 14 during the cleaning process. When the anode steel claw 14 is sent to the catenary stopper 11 by the catenary transport trolley 12 along the cantilever rail 10, the fixing fixture 4 holds the anode guide rod 13 to prevent the anode steel claw 14 from shaking during the rust removal process.

[0031] The detection sensor 5 can be contact or non-contact. The detection sensor 5 is used to detect the position of the anode steel claw 14 and the distance from the horizontal mounting frame 2 to the anode steel claw 14. By automatically adjusting the horizontal telescopic drive mechanism 2.2, it ensures the effective contact between the striking head 1.1 and the anode steel claw 14, ensuring that the pneumatic high-frequency striking head 1.1 can act on the anode steel claw 14.

The dust collecting hood 7 covers the action equipment and the working area to prevent rust and dust from flying around. The dust collecting hood 7 is to prevent the cleaned rust and impurities from flying around, and also to better achieve negative pressure dust collection.

[0034] The negative pressure dust collector 8 is connected to the dust collecting hood 7 through the dust suction pipe 8.1 to ensure that the dust collecting hood is in a negative pressure state. The negative pressure dust collector 8 forms a negative pressure to collect the removed rust and dust in an orderly manner to prevent flying everywhere and polluting the environment.

[0035] The equipment frame 9 adopts a door-shaped frame, which can be used as equipment support, can be used for the lifting platform 3 to slide up and down, can also be used for the installation of the detection sensor 5, and can also be used for the installation of the dust collection cover 7 and the fixing fixture 4.

[0036] In the production of aluminum electrolytic anode assembly workshop, the rust and other impurities on the anode steel claws should be cleaned before the anode carbon blocks and anode steel claws enter the pouring station to reduce the resistance after pouring due to rust and other impurities, which increases energy consumption and even causes the carbon block to separate from the steel claws during use, causing production accidents. The online rust removal device for anode steel claws uses a mechanical mechanism combined with high-frequency vibration to automatically loosen or remove rust and other adhered impurities online. The negative pressure dust collector collects the dust at the same time, reducing the impurities attached to the steel claws and the pouring resistance, which plays a great role in energy saving and consumption reduction in subsequent production processes.
