Technical Field
The utility model relates to an unpowered separating screen, in particular to an unpowered separating screen of carbon fine powder for aluminum.
Background
The anode carbon block is used in an electrolytic cell, and the consumption of electrochemical reaction is 1.6-2.2cm per day. In the using period of the anode carbon block, the anode mechanism drives the anode carbon block to descend along with the gradual consumption of the anode so as to ensure the stable polar distance of the electrolytic cell. When used for a certain period of time, the carbon block has become very thin (about 13-18cm), and in order to prevent the anode steel stud from being melted by the electrolyte, a new group of anode carbon blocks must be replaced, and the residual carbon blocks taken out are called residual anodes, and the residual anode amount is generally 15% -25% of the anode carbon block amount.
Solid iron in the broken residual anode is removed by a plurality of deironing devices such as a belt deironing device, a roller deironing device, a disc deironing device and a pipeline deironing device in the conveying process, but partial unseparated free iron is carried in the residual anode, a small amount of ferrophosphorus tightly combined with the anode is also removed by pressure and blanking when the residual anode is pressed and removed, and the partial iron is difficult to remove by the deironing device in the conveying process due to dispersion, fine particles and light weight, so that the residual anode enters a batching production line.
The Fe, Na and Ga elements in the prebaked anode mainly come from anode scrap, and particularly the Fe and Na elements account for more than 50 percent. The Fe element in the aluminum liquid mainly comes from the anode. The Fe, Na and Ga elements in the prebaked anode mainly come from the anode scrap, the trace elements in the anode scrap are mainly concentrated in the fine residues, the trace elements in the fine residues are mainly concentrated in the superfine residues, and the high efficiency of the Fe, Na and Ga elements in the superfine residues on the anode reaches 30%, 28% and 8% respectively.
Therefore, an unpowered separating screen for carbon fine powder for aluminum is particularly needed to solve the existing problems.
