Description
Technical Field
The utility model belongs to the field of alloy smelting production equipment, relates to effective elimination of dross on the surface of alloy liquid in the alloy smelting process, and in particular relates to a system device for effectively removing dross on the surface of alloy liquid in a smelting furnace.
Background
Typically, the first step in preparing the alloy material is alloy melting. In the smelting process, various scum is easy to appear on the surface of alloy liquid in a smelting furnace, on one hand, the existence of the scum is favorable for preventing external oxygen from contacting with the alloy liquid, on the other hand, when the alloy liquid is transferred into a die to be solidified, the scum is easy to carry into a cavity of the die, after the alloy liquid is solidified, scum particles are fixed in an alloy ingot, and the small particles have a very adverse effect on the performance of the alloy. In order to eliminate the adverse effect of the wrung scum as much as possible, a plurality of deslagging measures are invented. For example, the patent number of patent grant CN 218884671U, the patent name is an utility model patent of aluminum alloy refining slag removal frame, in the technical field of aluminum alloy refining, designed a slag removal frame, compared with pure manual slag removal, the labor intensity of workers is reduced, and meanwhile, the labor efficiency is also improved.
The effect of such an increased slag-stopping means to remove dross from the surface of the alloy liquid can be illustrated by means of living examples. For example, in life, most of the oil floats on the water surface, if it is desired to transfer the oil-water mixture in the cup to another container, and the liquid transferred to the other container is required to be entirely water. The physical barrier method does not remove the oil layer on the water surface completely, and a small amount of oil is always transferred to a new container together with water. Therefore, in industrial production, most of the dross on the surface of the alloy liquid can be removed by adding a slag blocking device, but a small amount of dross is still trapped in the alloy liquid during the transfer process.
Common sense of life teaches that when we are taking water from below the oil/water interface, the oil is totally floating on the surface of the water, so the water taken is totally free of oil, for example, when the needle is always below the oil/water interface, and the needle is used for taking water, the liquid sucked into the needle is definitely all the water. When the flow guide pipe is penetrated into the alloy liquid, the port of the flow guide pipe is close to the bottom of the smelting furnace, and the other section of the flow guide pipe is positioned outside the smelting furnace, and the lower part of the port of the section is right at the die opening. Therefore, once the alloy liquid can be continuously injected into the die from the smelting furnace through the guide pipe, the influence of scum can be completely avoided, and the purity of the alloy liquid in the die is ensured. The key problem to be solved is how to design a system device, through which the alloy liquid can be continuously injected into the mould through the flow guide pipe.

A groove (not shown) is formed in the edge of the opening of the collecting groove 11, a graphite gasket 13 for sealing is arranged in the groove, and the size of the graphite gasket 13 is matched with the sealing cover 11 and the collecting groove 12;

Further, the draft tube 3 comprises a first port 31 near the receiving trough 11 and a second port 32 near the smelting furnace 9, the height of the first port 31 being smaller than the height of the second port 32.

A mechanical vacuum pump (not shown) is connected to the third branch 53 for evacuating the sealed tank.
Further, the pipe diameter of the flow guiding pipe 3 is 0.3cm-45cm, and the flow guiding pipe 3 is made of a material which is high-temperature resistant and does not react with the alloy liquid 92.
In use, if the mold used can be directly evacuated, as shown in FIG. 1, the mold may be used in a manner corresponding to the use of the collecting tank 11 to directly collect the alloy liquid 92. If the mold used cannot be directly evacuated, as shown in fig. 3, the sealed can 1 is subjected to air pressure adjustment, and the mold 10 is placed in the sealed can 1 for collecting the alloy liquid 92.
In particular, in example 1, if the mold used can be directly evacuated, the mold may correspond to the case of using the collecting tank 11. As shown in FIG. 1, the use flow of the utility model is that firstly, a graphite gasket 6 is placed in a groove of a collecting tank (mold) 11, then a sealing cover 12 (comprising all accessories such as a flow guide pipe 3 fixed on the sealing cover 12) is placed on the collecting tank (mold) 11, and the collecting tank (mold) and the sealing cover 12 are fixed, and the assembled sealing cover is shown in FIG. 2.
The first valve 6 on the gas filling pipeline 4 is opened to fill gas into the collecting tank (mould) 11, and the flow guiding pipe 3 is always communicated with the outside, so that the filled gas is discharged from the second port 32 through the flow guiding pipe 3, when the second port 32 is continuously sensed to be discharged, the second port 32 of the flow guiding pipe 3 is immersed into the alloy liquid 92 until the position adjacent to the bottom of the smelting furnace 9, the first valve 6 on the gas filling pipeline 4 is closed, and gas filling is stopped.
After the mechanical vacuum pump is started, a third valve 8 on a third branch 5 of the three-way pipeline 5 is slowly opened. As the mechanical vacuum pump operates, the air pressure in the collection tank (mold) 11 is continuously reduced, and the alloy liquid 92 gradually enters the draft tube 3 under the influence of the atmospheric pressure, flows out from the first port 31 of the draft tube 3, and is injected into the collection tank (mold) 11. When the alloy liquid 92 is seen from the quartz glass observation window 2 to be injected into the collecting tank (mold) 11, the third valve 8 of the third branch 53 is closed, the mechanical vacuum pump is turned off, and the second valve 7 of the second branch 52 is opened to the atmosphere. On the premise that the volume of the collecting tank (mould) 11 is larger than the volume of the alloy liquid 92 in the smelting furnace 9, observing the change of the scum 91 and the liquid level of the alloy liquid 92 in the smelting furnace 9, and closing the second valve 7 of the second branch 52 when the scum 91 is adjacent to the bottom of the smelting furnace 9. The second port 32 of the flow guide 3 is moved to a position higher than the dross 91 (still in the smelting furnace 9), the first valve 6 of the gas filling pipe 4 is opened, and the gas flowing into the collecting tank (mold) 11 flows out from the second port 32 of the flow guide 3, and the liquid 92 drops of the alloy liquid remaining on the inner wall of the flow guide 3 are removed by the gas flow. When the second port 32 of the flow guide pipe 3 is found, no liquid drops fly out, the first valve 6 of the air filling pipeline 4 is closed, and the flow guide pipe 3 is moved out of the smelting furnace 9. If the production is continuous, the materials are fed into the smelting furnace 9 for smelting, after the alloy liquid 92 is smelted uniformly, the collecting tank (die) 11 is replaced, the operation of the flow is repeated, if the smelting is not needed, the scum 91 and the residual materials in the smelting furnace 9 are only needed to be removed, and the residual materials can be stored independently, so that the residual materials are added into the smelting furnace 9 to be melted together with new materials when the same alloy is produced next time.
Because the alloy liquid 92 in the collecting tank (die) 11 is collected from the position below the dross 91/alloy liquid 92 interface of the smelting furnace 9, the collected alloy liquid 92 is ensured to have no dross 91, and the problem of doping a small amount of dross 91 in the alloy is solved.
In particular, in example 2, if the mold 10 used cannot be directly evacuated, the mold 10 is placed in the sealed vessel 1 for collecting the alloy liquid 92, such as an open-die mold, and such a mold cannot be directly evacuated.

After placement of the mold 10, the closure 12 is placed over the collection trough 11 and secured by screws or other means, as shown in fig. 4.
The first valve 6 of the gas filling pipeline 4 is opened to charge gas into the sealed tank body 1, and the flow guide pipe 3 is always communicated with the outside, so that the charged gas is discharged from the second port 32 of the gas filling pipeline 3, when the second port 32 is continuously sensed to flow out of the gas, the second port 32 is immersed into the alloy liquid 92 at a position adjacent to the bottom of the smelting furnace 9, the first valve 6 on the gas filling pipeline 4 is closed, and gas filling is stopped. After the mechanical vacuum pump is started, the third valve 8 of the third branch 53 of the three-way pipeline 5 is slowly opened, the air pressure in the sealed tank 1 is continuously reduced along with the operation of the mechanical vacuum pump, the alloy liquid 92 gradually enters the guide pipe 3 and flows out of the first port 31 of the guide pipe 3 to be injected into the lower mold 10, when the alloy liquid 92 is seen from the quartz glass observation window 2 to be injected into the mold 10, the third valve 8 of the third branch 53 is closed, the mechanical vacuum pump is closed, the second valve 7 of the second branch 52 is opened, and the air is communicated.
If the capacity of the mould 10 is smaller than the volume of the alloy liquid 92 in the smelting furnace 9, the change of the liquid level of the alloy liquid 92 in the mould 10 is continuously focused through the quartz glass observation window 2, when the liquid level of the alloy liquid 92 in the mould 10 is higher, the second port 32 of the flow guide pipe 3 is moved to a position higher than the scum 91 in the smelting furnace 9, the second valve 7 of the second branch 62 is closed, the first valve 6 of the air-filling pipeline 4 is opened, the gas injected into the sealed tank 1 flows out from the flow guide pipe 3, the residual liquid drops of the alloy liquid 92 on the inner wall of the flow guide pipe 3 are removed by means of gas flow, the first valve 6 of the air-filling pipeline 4 is closed when the liquid drops are not flying out at the second port 32 of the flow guide pipe 3, the sealed tank 1 is opened, and the operation of collecting the alloy liquid 92 in the next round is performed after the mould 10 is replaced.
If the capacity of the mould 10 is larger than the volume of the alloy liquid 92 in the smelting furnace 9, the change of the scum 91 and the liquid level of the alloy liquid 92 in the smelting furnace 9 is observed, when the scum 91 is adjacent to the bottom of the smelting furnace 9, the second valve 7 of the second branch 52 is closed, the second port 32 of the flow guide pipe 3 is moved to a position higher than the scum 91 (still positioned in the smelting furnace 9), the first valve 6 of the air-adding pipeline 4 is opened, the gas flowing into the mould 10 is removed from the second port 32 of the flow guide pipe 3, the residual liquid 92 drops on the inner wall of the flow guide pipe 3 are removed by means of the gas flow, and when the second port 32 of the flow guide pipe 3 is found, the first valve 6 of the air-adding pipeline 4 is closed, and the flow guide pipe 3 is moved out of the smelting furnace 9.
If the production is continuous, the materials are fed into the smelting furnace 9 for smelting, after the alloy liquid 92 is smelted uniformly, the operation of the process is repeated after the mould 10 is replaced, if the smelting is not needed, the scum 91 and the residual materials in the smelting furnace 9 are only needed to be removed, the residual materials can be stored independently, and then the residual materials are added into the smelting furnace 9 to be melted together with new materials when the same alloy is produced next time.
Since the alloy liquid 92 in the die 10 is collected from below the dross 91/alloy liquid 92 interface of the smelting furnace 9, the collected alloy liquid 92 is ensured to have no dross 91, and the problem of doping a small amount of dross 91 in the alloy is solved.
