[0002] Aluminum reduction cells are the primary technical equipment for electrolytic aluminum production. They consist primarily of two main components: the molten pool at the bottom and the superstructure. The anode is one of the most core components of this superstructure and primarily includes the anode aluminum guide rod, aluminum-steel explosive weld block, anode steel claw, and anode carbon block.

[0003] The function of phosphorus pig iron in the anode assembly process is to connect the new anode carbon block and the guide rod group together. The connection part is between the steel claws of the guide rod group and the bowl gap of the carbon block. The molten phosphorus pig iron contained in the ladle is poured into the gap between the steel claws and the carbon bowl with the help of a pouring machine. After cooling, the guide rod group and the carbon block are combined into one and transported to the electrolysis process for use.

[0004] The current production process primarily involves manual pouring using a pouring cart. This process takes a long time to pour the entire anode, and the four carbon bowls cannot be poured simultaneously, increasing labor costs during the production of aluminum electrolytic anodes.

[0018] See Figure 1-7 In the present invention, a low-pressure environment vacuum arc chamber power frequency withstand voltage detection device includes a box body 1, and a plurality of processing cavities that are independently arranged and open to the outside are formed on the inner side of the box body 1, and the processing cavities include a main cavity 100 and a sub-cavity 101; a discharge pipe 2, the discharge pipe 2 is arranged at the upper end of the side wall of one side of the box body 1, and is interconnected with the sub-cavity 101; a discharge pipe 10, the discharge pipe 10 is arranged at the lower end of the side wall of one side of the box body 1, and is interconnected with the main cavity 100; an air-controlled pressurization port 11, the air-controlled pressurization port 11 is arranged on the upper end surface of the clamping cover 6, and is interconnected with the main cavity 100.

[0019] When in use, the box body 1 is assembled from the outside to the inside using silicon carbonitride plates combined with refractory castables, nano-insulation boards and ceramic fiber boards as the main processing body; and the multiple independent processing cavities formed on the inside include a main cavity 100 and a sub-cavity 101. The number of processing cavities formed is preferably four groups, each group corresponding to a main cavity 100 and a sub-cavity 101, which is simple to manufacture, low in cost and easy to operate. The cavities are independent of each other to ensure that each cavity can be individually controlled by an intelligent air control device. The main cavity 100 serves as the main processing area, and the cavity 101 serves as the processing adjustment area. The air control pressurization port 11 set on the pressing cover 6 can be used to pass air into the inside of the main cavity 100, and the amount of compressed air introduced can be adjusted so that the high-temperature ferrophosphorus liquid inside the main cavity 100 is moved to the sub-cavity 101 to achieve the height of the ferrophosphorus liquid level in the box, thereby realizing the automatic pouring of ferrophosphorus into the anode steel claws of the aluminum electrolytic cell. The discharge pipe 2 of the auxiliary inner cavity 101 is arranged at the upper end of the side wall of one side of the box body 1, and is at a certain distance from the lower end surface, so that the auxiliary inner cavity 101 can store more high-temperature ferrophosphorus liquid. When it reaches the discharge pipe 2, the excess high-temperature ferrophosphorus liquid is discharged through the discharge pipe 2, and the discharge pipe 10 is placed at the lower end of the side wall of one side of the box body 1, so as to discharge the residue on the lower wall of the main inner cavity 100. A sealed component is set in the main inner cavity 100, and the sealed component includes a support frame 5, a pressing cover 6, an adjusting rod 8, a support block 9, The support frame 5 is arranged on the upper end face of the box body 1 and is located at the opening of the main inner cavity 100, and the upper end face is provided with the adjusting rod 8. One end of the adjusting rod 8 passes through the support frame 5 and is connected to the clamping upper cover 6. The upper opening of the main inner cavity 100 is sealed by the provided clamping upper cover 6. The provided adjusting rod 8 can be made into a bolt rod, which is threadedly matched with the support frame 5. By screwing in the adjusting rod 8, pressure is continuously applied to the clamping upper cover 6 to ensure the sealing of the main inner cavity 100 opening with respect to the clamping upper cover 6.

[0020] In this example, the sealing assembly further comprises a sealing plate 7 disposed between the compression cover 6 and the adjustment rod 8. The sealing plate 7 serves as a transitional connector between the compression cover 6 and the adjustment rod 8. The compression cover 6 can be squeezed simply by rotating the adjustment rod 8 and continuously squeezing the sealing plate 7. The compression cover is equipped with a lifting handle 12 and is provided with an air inlet flange and an air inlet pipe for connection to air control equipment to complete the pressurization operation of the split cavity within the box.

[0021] Specifically, the main inner cavity 100 and the auxiliary inner cavity 101 are provided with a baffle 110, and a certain distance is provided between the baffle 110 and the inner bottom wall of the working inner cavity to form a transition channel, so as to facilitate the amount of compressed air introduced into the inner side of the main inner cavity 100, so that the high-temperature ferrophosphorus liquid inside the main inner cavity 100 flows to the auxiliary inner cavity 101.

[0022] Specifically, the discharge pipe 2 is connected to the discharge pipe 4 through the discharge flange 3 at one end away from the box body. The discharge channel is extended by connecting the discharge pipe 4 to the discharge flange 3 to facilitate collection.

[0023] Specifically, an overflow hole 13 is provided on the partition between the two adjacent sub-cavities 101. For safety reasons, when the high-temperature ferrophosphorus liquid inside the sub-cavity 101 exceeds the discharge pipe 2, it can be discharged into the adjacent cavity in time to avoid excessive splashing of high-temperature liquid.

[0024] Specifically, the inner bottom wall of the working cavity gradually decreases from the discharge pipe 2 to the unloading pipe 10 to form an inclined surface so that the waste liquid can flow out of the unloading pipe 10 better.

[0025] In addition to the above-mentioned preferred embodiments, the present invention has other implementation modes. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
