Description

Technical Field

[0001] The invention relates to the technical field of prebaked anode production, and more specifically to an environmentally friendly cleaning device for a prebaked anode carbon bowl for aluminum. Background Art

[0002] Prebaked anode is made of petroleum coke and asphalt coke as aggregate and coal tar as binder, and is used as anode material for prebaked aluminum electrolytic cells.

[0003] Modern electrolytic aluminum industry uses prebaked anodes to produce electrolytic aluminum. Prebaked anodes are generally rectangular parallelepipeds with stable geometric shapes. They use rock tar and asphalt coke as aggregates and coal tar as binder. They have different sizes according to the size of the electrolytic cell current and the process. Their current density is generally in the range of 0.68-0.9A / cm2, and the service life of each carbon block is generally 23-30 days. In the existing technology, the anode steel claws and anode carbon blocks are all connected by phosphorus pig iron casting. There are 2-4 circular grooves with a diameter of 160-180mm and a depth of 80-110mm on the upper surface of the prebaked anode carbon block in the conductive direction, commonly known as carbon bowls. When the anode is assembled, the carbon bowl is used to place the anode steel claws. The anode steel claws are cast in the carbon bowl with phosphorus pig iron. The steel claw head and the aluminum conductive rod are connected by aluminum-steel explosion welding. In this way, the anode conductive rod and the anode carbon block are connected as a whole to form an anode carbon block group.

[0004] At present, most anode carbon block carbon bowls adopt manual cleaning methods, which have slow cleaning efficiency, high labor intensity, and easily cause dust pollution to the human body, affecting human health. Subsequently, people developed some simple carbon bowl cleaning tools, but the cleaning effects were not good.

[0045] Working principle:

[0046] First, the prebaked anode is placed on the feed end of the first roller conveyor 2. When placing the prebaked anode, it is turned upside down with one side of the carbon bowl facing the carbon bowl cleaning mechanism 6. When it is at the feed end of the first roller conveyor 2, the side cleaning mechanisms 5 located on both sides of the feed end of the first roller conveyor 2 clean one side of the prebaked anode and the side where the carbon bowl is located. Then, the prebaked anode is transported by the first roller conveyor 2 to the discharge end of the first roller conveyor 2. Since the side cleaning mechanism 5 is provided at the discharge end of the first roller conveyor 2 to block the prebaked anode, the prebaked anode stays here. At this time, the side cleaning mechanism 5 cleans one side of the prebaked anode facing it. After the set time is reached, the first hydraulic cylinder 9, driven by the hydraulic station, pushes the prebaked anode to the second roller conveyor 3.

[0047] When the prebaked anode moves to the discharge end of the second roller conveyor 3, it is blocked by the limit block 11, so the prebaked anode stays here. At this time, the side cleaning mechanism 5 located on the side of the discharge end of the second roller conveyor 3 cleans the side of the prebaked anode, and under the drive of the third hydraulic cylinder 66, the carbon bowl cleaning mechanism 6 moves as a whole, and the wire brush head 63 can be extended into the carbon bowl. Under the action of the second drive motor 62, the inside of the carbon bowl is cleaned. After the set time is reached, it exits under the drive of the third hydraulic cylinder 66.

[0048] At this time, the second hydraulic cylinder 10 drives the side cleaning mechanism 5 connected to its piston rod to move the side cleaning mechanism 5 as a whole, and then push the prebaked anode to the third roller conveyor 4. During the pushing process, the prebaked anode passes through the scraper mechanism 7, and the upper and lower surfaces of the prebaked anode are cleaned by the upper scraper and the lower hanging knife. At this time, the cleaning of the six surfaces of the prebaked anode and the carbon bowl is completed.

[0049] Under the action of the third roller conveyor 4, the prebaked anode enters the cover 81 of the high-pressure airflow cleaning mechanism 8 for thorough cleaning by the high-pressure airflow. The large pieces of residue that are washed off are collected in the residue recovery box 83, and the diffused dust enters the cyclone dust collector 14 and the bag dust collector 12 through the pipe for secondary dust removal treatment to avoid dust pollution to the environment.

[0050] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
