Description
Technical Field
The utility model relates to a metal and alloy preparation field particularly, the utility model relates to a siphon is changeed and is annotated device and siphon that has this siphon and change notes device and change notes system.
Background
In the aspect of preparing aluminum and its alloy, transferring the aluminum liquid from the electrolytic bath or other storage tank to the next process is an indispensable step. For example, in the primary aluminum electrolysis production industry, aluminum liquid needs to be transferred from an electrolytic bath to a mixing furnace in a foundry, and the currently adopted mode is to suck the aluminum liquid from the electrolytic bath to a ladle chamber by using a vacuum ladle, transport the ladle to the foundry, and then transfer the aluminum liquid to the mixing furnace by the ladle in a pouring mode; the aluminum-scandium master alloy is produced by a molten salt electrolysis method, and the aluminum-scandium master alloy liquid obtained by electrolysis needs to be transferred from an electrolytic bath to a refining furnace for impurity removal and homogenization.
At present, the main ways of producing the aluminum liquid are vacuum ladle and siphon. The vacuum ladle is characterized in that after the ladle aluminum suction pipe is inserted into the electrolytic bath, a certain vacuum degree is generated in the ladle cavity through the vacuum generating device, aluminum liquid enters the ladle cavity from the liquid inlet, and after the ladle filled with the aluminum liquid is transported to the next working procedure, the aluminum liquid is poured out from the ladle liquid outlet in a pouring mode. This manner of "dumping" the aluminum tends to produce a large amount of aluminum oxide dross. The main factors affecting the formation of oxides in the molten metal are temperature, turbulence, and oxygen. The oxidation speed of the aluminum liquid by oxygen is greatly improved when the aluminum liquid is at high temperature. In addition, the aluminum liquid is discharged in a pouring mode, turbulence can be caused, and the turbulence continuously provides a fresh molten aluminum surface for the formation of oxides. The aluminum liquid is in a high-temperature state, and in the aluminum discharging mode, the aluminum liquid can not be stably transferred, and the turbulent flow continuously provides a fresh high-temperature aluminum liquid surface, so that a large amount of aluminum oxide slag is generated in the aluminum liquid. The turbulence caused by the higher temperature and the 'dumping' of the aluminum liquid is the root cause of the oxidation of the aluminum liquid and the generation of a large amount of scum. For example, according to the report of relevant data and statistical data of some electrolytic aluminum casting workshops, the aluminum liquid is transferred into the mixing furnace in a vacuum ladle pouring mode, and the burning loss rate of the aluminum liquid is as high as 0.8% -2.0%. Taking an electrolytic aluminum plant with the capacity of 30 ten thousand tons as an example, the metal burning loss caused by the transfer injection of aluminum liquid is up to 2400-6000 tons each year. If the average market price of the current aluminum ingot is 14000 yuan/ton, the economic loss of the aluminum liquid can reach 3360 ten thousand to 8400 ten thousand yuan if the aluminum liquid is burnt.
Another way to transfer the aluminum liquid is to use a siphon. Siphon tubes have been developed in two general forms, as shown in fig. 1 (a) and (b). The siphon in the two forms has the same principle fundamentally, and the liquid inlet and the liquid outlet have delta h0The height difference is utilized to generate a siphon effect so as to realize the transfer injection of the aluminum liquid. When in use, the liquid inlet A0Inserted into a furnace (called as a "liquid feeding furnace") filled with aluminum liquid, and a liquid outlet B0Inserting into a furnace (called as a "liquid receiving furnace") for receiving the aluminum liquid, scooping a certain amount of aluminum liquid from the liquid feeding furnace to the liquid receiving furnace manually, liquid sealing the liquid outlet, and the amount of aluminum liquid scooped manually to the liquid receiving furnace at least needs to be capable of filling the liquid outlet section H of the siphon tube0Height, the siphon effect can be generated under the principle of the structure. At the moment, the liquid inlet and the liquid outlet are both sealed by aluminum liquid, and the opening C is arranged0Connecting the vacuum generator, starting the vacuum generator to gradually pump out air in the siphon tube to generate negative pressure inside the siphon tube. Under the action of atmospheric pressure, the aluminum liquid enters the siphon tube from the liquid inlet and the liquid outlet at the same vertical speed. Because the liquid inlet and the liquid outlet have a height difference deltah0When the rising heights of the aluminum liquid at the two ends reach H0The height of the aluminum liquid at the liquid outlet reaches the height shown in the figure L0When the molten aluminum is ignited, the molten aluminum at the liquid inlet end reaches the highest point T of the molten aluminum channel of the siphon tube0And keeping the negative pressure, so that the aluminum liquid flows along the direction shown by the arrow in the figure, the siphon effect is formed, and the aluminum liquid is transferred from the liquid inlet to the liquid collecting furnace through the siphon pipe. The pressure of the aluminum liquid in the liquid inlet is P-rho gH0The pressure of the metal liquid at the liquid outlet is P-rho g (H)0+Δh0) Wherein P is atmospheric pressure, rho is the density of the aluminum liquid, and g is the acceleration of gravity. The pressure of the liquid inlet is greater than that of the liquid outlet by rho g delta h0And the aluminum liquid is transferred and injected due to the existence of pressure difference.
However, the siphon pipes with the two structures have three disadvantages in use: 1) when the siphon is used, the vacuum generating device is opened, and because the siphon is directly connected with the vacuum generating device, the vacuum generating device has no buffer device, and if the negative pressure is slightly overIf the aluminum liquid is large or unstable in control, the aluminum liquid is easily sucked into a hose of the vacuum generating device or even the vacuum generating device from the interface of the aluminum liquid and the vacuum generating device by negative pressure, so that accidents occur and production is influenced; 2) according to the using principle of the siphon, the liquid outlet and the liquid inlet are both required to be sealed by aluminum liquid. When the siphon liquid container is used, a part of aluminum liquid needs to be manually transferred from a furnace for containing the aluminum liquid to a liquid receiving furnace in advance so that the aluminum liquid can seal the liquid outlet of the siphon tube, and the amount of the manually scooped aluminum liquid at least ensures that the H at the liquid outlet end of the siphon tube can be filled with the manually scooped aluminum liquid0Height. After the vacuum generating device is started, negative pressure can be generated in the tube. Therefore, the siphon tube needs a manual liquid scooping process in production. For the production line with large molten aluminum amount needing to be transferred, the siphon is also relatively thick and long, and the molten aluminum amount manually scooped to the aluminum receiving furnace needs to at least ensure that the molten aluminum amount can be filled with H at the liquid outlet end of the siphon0The height is larger than the amount of the aluminum liquid which needs to be transferred in advance, which prevents the aluminum liquid from being applied to a production line with larger capacity; 3) the transfer of the aluminum liquid can not be stopped midway. When the aluminum-scandium intermediate alloy is electrolyzed, the lower part in the electrolytic cell is aluminum liquid, the upper part of the aluminum liquid is molten salt, and during transfer, only the aluminum liquid is required to be transferred, but the molten salt is not required to be absorbed, so that when the aluminum liquid in the electrolytic cell is completely transferred, the siphon is required to stop working, and the siphon is prevented from continuously working to absorb the molten salt.
In conclusion, the existing aluminum liquid siphon transfer device still needs to be improved.
