[0002] In the production process of aluminum alloy, impurities are one of the main factors affecting the quality of aluminum alloy. Therefore, adding different refining agents to the aluminum liquid can significantly improve the performance and quality of the aluminum alloy. The general principle of aluminum liquid refining is to add the refining agent directly or indirectly to the aluminum liquid, so that the impurities in it react with the refining agent to generate non-metallic substances, which settle or float on the surface, thereby improving the purity and quality of the aluminum liquid.

[0003] At present, in the prior art, the aluminum liquid refining process usually directly pours the refining agent into the refining furnace on the top of the aluminum liquid, and then stirs and mixes the refining agent and the aluminum liquid through a stirring device provided in the refining furnace. Although this operation method is convenient for adding the refining agent, it often causes a certain amount of refining agent to accumulate on the top of the aluminum liquid, which easily leads to uneven mixing of the refining agent and the aluminum liquid in the refining furnace during the refining process. Especially when the refining furnace cavity is large, not only is the stirring device required to have a higher working efficiency, but the working time of the stirring device is further increased. The refining effect is not ideal and the efficiency of aluminum liquid refining is also reduced. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0023] See also Figure 1-4 The present embodiment relates to a regenerative aluminum liquid refining furnace 1, comprising a refining furnace 1 main body, wherein a stirring assembly 2 is arranged inside the refining furnace 1 and is driven to rotate by a first driving component 101 arranged at the bottom thereof, wherein the stirring assembly 2 comprises a first stirring shaft 21, wherein a second stirring shaft 22 is sleeved on the outer side of the first stirring shaft 21, wherein a plurality of conveying pipes 221 are arranged inside the second stirring shaft 22 and a plurality of stirring rods are surrounded on the outer side, wherein a plurality of through holes are opened on the stirring rods and are surrounded at different heights on the outer wall of the second stirring shaft 22 and are connected to the conveying pipe 221 adapted to be arranged inside the second stirring shaft 22, and a receiving cavity 222 is arranged on the top of the second stirring shaft 22.

[0024] Specifically in this embodiment, a certain amount of aluminum liquid is poured into the refining furnace 1. After the aluminum liquid is added, the first driving component 101 provided at the bottom of the refining furnace 1 drives the stirring component 2 inside the refining furnace 1 to rotate, thereby stirring the aluminum liquid in the refining furnace 1. During the rotation of the stirring component 2, Figure 3-4As shown, the refining agent required for aluminum liquid refining can be added into the accommodating chamber 222 on the second stirring shaft 22, and the refining agent placed in the accommodating chamber 222 can reach the connection with several stirring rods below through several conveying pipes 221 provided in the second stirring shaft 22. Specifically, the first driving component 101 drives the first stirring shaft 21 and the second stirring shaft 22 sleeved on its outer side to rotate, and the rotation of the second stirring shaft 22 causes the internal conveying pipe 221 and several stirring rods surrounding the outer side to rotate synchronously. The refining agent in the second stirring shaft 22 that reaches the connection between the conveying pipe 221 and the stirring rod can enter the interior of the stirring rod under the action of the centrifugal force generated when the second stirring shaft 22 rotates, and contacts the aluminum liquid in the refining furnace 1 through several through holes provided on the stirring rod, and drives the second stirring shaft 22 and the stirring rod to rotate under the drive of the first driving component 101. Thereby, the refining agent and the aluminum liquid are fully mixed. This operation mode is not only convenient for adding and adjusting the refining agent, but also, in cooperation with the stirring component 2 inside the refining furnace 1, the refining agent can reach the inside of the aluminum liquid through the conveying pipe 221, and the refining agent can reach different depths and positions in the aluminum liquid and be mixed through a plurality of stirring rods arranged at different heights on the outer wall of the second stirring shaft 22, thereby reducing the occurrence of uneven mixing and further improving the refining effect and work efficiency. In addition, the design of the refining furnace 1 with the stirring component 2 allows the conveying pipe 221 inside the second stirring shaft 22 and the stirring rods surrounding the outside thereof to be evenly distributed and arranged according to the size of the furnace front of the specific refining furnace 1, so as not to be affected by the size of the furnace chamber, further improving the mixing degree and mixing efficiency of the refining agent and the aluminum liquid, further shortening the time required for mixing, further improving work efficiency, and improving applicability.

[0025] The stirring rod is rotatably arranged on the conveying pipe 221 and is arranged at a certain angle. Specifically, the stirring rod is arranged obliquely downward along the bottom of the refining furnace 1. Under the rotation of the second stirring shaft 22 and the stirring rod, the rate at which the refining agent in the conveying pipe 221 reaches the stirring rod can be further accelerated, and the stirring efficiency and mixing uniformity can be further improved. In addition, the stirring rod is rotatably arranged on the conveying pipe 221, so that under the drive of the first driving shaft and the second stirring shaft 22, the stirring rod contacts the inside of the aluminum liquid in the refining furnace 1 during the rotation process and has a certain inertia force in its rotation direction, so that it can rotate synchronously along the direction of its conveying pipe 221, further improving the mixing effect of the refining agent and the aluminum liquid.

[0026] The top of the refining furnace 1 is connected to a matching sealing cover 3 through a fastener 4, and an observation window 31 is provided on the sealing cover 3. Figure 1As shown, a sealing cover 3 is provided on the top of the refining furnace 1. The sealing cover 3 can seal the refining furnace 1 and can be provided according to different usage requirements, thereby further preventing the leakage of molten aluminum during the refining process or the leakage of harmful gases generated by it. At the same time, the sealing cover 3 is fastened by a fastener 4 provided on the top of the refining furnace 1, so that the interior of the refining furnace 1 has a certain sealing property, reducing the heat loss generated by the molten aluminum during the refining process and affecting the refining effect. In addition, an observation window 31 is provided on the sealing cover 3. While ensuring that the interior of the refining furnace 1 has a certain sealing property, the real-time state of the molten aluminum can be conveniently observed and adjusted through the observation window 31, thereby improving the convenience of use.

[0027] The accommodating chamber 222 is also provided with a material guide plate 5 which is rotatably disposed therein. The material guide plate 5 is provided with a plurality of material guide holes 51 adapted to the plurality of conveying pipes 221.

The refining agent stored in the accommodating chamber 222 can be mixed under the rotation of the guide plate 5 and evenly enter the conveying pipe 221 below through the guide hole 51, which is convenient for operation and further improves the mixing uniformity of the refining agent and the aluminum liquid. It is not easy to cause uneven mixing due to excessive or insufficient refining agent locally, which affects the refining effect. At the same time, it can also further reduce the waste of refining agent, improve the utilization rate of refining agent and further reduce the use cost.

[0028] The guide plate 5 and the second driving component 102 are respectively installed in the accommodating cavity 222 and on the sealing cover 3 through an adapted detachable structure, as shown in FIG.

Figure 3 or Figure 5As shown, the stirring paddle 211 can further improve the stirring effect of the stirring component 2, strengthen the disturbance of the internal aluminum liquid and fully mix it with the refining agent, thereby improving the effect and avoiding the phenomenon that impurities generated by the refining agent or aluminum liquid during the refining process accumulate at the bottom of the refining furnace 1 for a long time and affect the refining effect.

[0030] The refining furnace 1 is also provided with a heating component, which includes a heating pipe 61. The heating pipe 61 is arranged around the side wall and the bottom of the refining furnace 1 and is connected to a temperature controller 62 arranged on the main body of the refining furnace 1. For details, see Figure 5 As shown, the refining furnace 1 can observe and adjust the temperature of the aluminum liquid inside it in real time during the aluminum liquid refining process through the temperature controller 62, and evenly heat the aluminum liquid inside the refining furnace 1 through the heating tubes 61 arranged around the side walls and the bottom of the refining furnace 1, thereby meeting the different temperature requirements during the aluminum liquid refining process, reducing the heat loss of the aluminum liquid inside the refining furnace 1, and further accelerating the reaction rate of the refining agent and the aluminum liquid, thereby improving the refining effect and refining efficiency.

[0031] A liquid pouring port 11 is provided on the top side wall of the refining furnace 1, and a filter plate 112 of a suitable size is installed at the liquid pouring port 11 through a detachable structure, as shown in FIG.

During the pouring of the molten aluminum, the filter plate 112 arranged at the pouring port 11 can filter and separate impurities generated during the refining process of the molten aluminum. At the same time, the filter plate 112 is slidably arranged on the pouring port 11 through the trough body 111 arranged at the pouring port 11, thereby facilitating the installation, disassembly and replacement of the filter plate 112, meeting different usage requirements, and improving the convenience and flexibility of operation.
