Description

Technical Field

[0001] The utility model relates to the technical field of iron removal from molten aluminum, in particular to a device for removing iron from molten aluminum. Background Art

[0002] The principle of iron removal from molten aluminum is based on the differences in the physical and chemical properties of aluminum and iron. Iron removal is achieved through specific processes and additives. Common methods for removing iron from molten aluminum include flux removal and filtration. Flux removal involves adding specific fluxes to the molten aluminum. These fluxes react chemically with the iron in the molten aluminum to form compounds that are insoluble in the aluminum. These compounds are then separated from the molten aluminum through physical methods.

[0003] However, when using traditional aluminum liquid iron removal equipment, the method of introducing the specific solvent is simple. After the specific solvent is introduced through a single inlet, it cannot be dispersed into the aluminum liquid in time. It takes a long time to stir before the iron element in the aluminum liquid can fully react with the solvent, which is time-consuming and has low iron removal efficiency. Utility Model Content

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0017] The utility model discloses an aluminum liquid iron removal device mainly used in conventional aluminum liquid iron removal devices. When in use, the method of introducing a specific solvent is simple. After the specific solvent is introduced through a single inlet, it cannot be dispersed into the aluminum liquid in time. A long period of stirring is required before the iron element in the aluminum liquid can fully react with the solvent, which is time-consuming and has low iron removal efficiency.

[0019] Filtering and cleaning mechanism: The filtering and cleaning mechanism is arranged inside the processing barrel 1.

[0020] In this solution, the specific solvent for iron removal can be first added to the liquid supply tank 6 through the provided mixing introduction mechanism, and then the specific solvent in the liquid supply tank 6 is introduced into the hollow rod 7 through the conduit and the hose 5 using the booster pump, so that the specific solvent can be discharged along the liquid outlet 15 on one side of the dispersed stirring rod 8, so that the introduced solution can be directly dispersed into the aluminum liquid. Combined with the motor 4 to drive the stirring rod 8 to rotate, the solvent is fully promoted to react with the iron element in the aluminum liquid, and the iron removal effect is better.

[0021] Among them, the stirring rod 8 is set to an arc structure, the driving direction of the motor 4 is counterclockwise, and the liquid outlet 15 is set on the concave side of the arc structure. When the motor 4 drives the hollow rod 7 to rotate counterclockwise, the convex side of the stirring rod 8 on the outer wall of the hollow rod 7 stirs against the liquid flow, and the liquid outlet 15 set on the concave side of the stirring rod 8 can synchronously disperse and introduce a specific solvent into it, and the stirring mixing and solvent introduction are coordinated to improve the reaction efficiency.

The ring box is connected to the hollow rod 7 through a bearing, and the ring box is connected to the inside of the hollow rod 7.

[0023] It should be noted that, by such connection and installation, it is possible to ensure that the motor 4 drives the hollow rod 7 to rotate stably, and it does not affect the transfer of the specific solvent from the liquid supply box 6 to the hollow rod 7, thereby ensuring the stable progress of the mixing and solution introduction process.

Four equally distributed supports 2 are provided on the bottom outer wall of the processing barrel 1 to facilitate the removal of the collecting partition 13.

[0026] Specifically, the precipitate produced by the reaction of the solvent with the iron element in the aluminum liquid can be collected by setting the collecting baffle 13. After the reaction is completed, under the action of the electric telescopic rod 9 and the U-shaped connecting rod 14, the collecting baffle 13 can be driven to lift the collected precipitate to the notch position at the top of the processing barrel 1. The collecting baffle 13 is removed from the limited state of the limit block 11 for cleaning, and then installed again after cleaning and placed back on the bottom of the processing barrel 1. The whole process is simple to clean and easy to disassemble and assemble.

[0027] Working principle: When in use, first introduce the aluminum liquid to be deironed into the processing barrel 1, then add the specific solvent for deironing into the liquid supply tank 6, and use the booster pump in the liquid supply tank 6 to introduce the specific solvent into the interior of the hollow rod 7 through the conduit and hose 5. At the same time, the motor 4 drives the hollow rod 7 to rotate, and the specific solvent entering the hollow rod 7 is dispersed and introduced into the processing barrel 1 from the liquid outlet 15 of the stirring rod 8 in the rotating state, and is fully mixed with the aluminum liquid. The reaction is more sufficient and efficient, and the deironing efficiency is higher.
