Description

Technical Field

[0001] The utility model relates to the technical field of smelting devices, in particular to an aluminum liquid refining device based on refining agent pretreatment. Background Art

[0002] Aluminum alloy has a small weight, low thermal expansion coefficient, good casting performance and wear resistance. The alloy castings cast with it have high impact resistance and good high-pressure density, so it has been widely used in many industries. In order to prevent shrinkage cavities and shrinkage in aluminum alloys and improve the quality of aluminum alloys, nitrogen needs to be filled in the process of smelting aluminum alloys to drive away the gas in the aluminum alloy solution, and refining agents need to be added to make the impurities in the aluminum alloy solution precipitate and float to the liquid surface to facilitate the removal of impurities.

The liquid aluminum refining device, through the coordinated arrangement of the screen plate, the screen holes, the grinding mechanism and the driving mechanism, when the refining agent is blown into the refining chamber, it will fall onto the screen plate, and the refining agent with a smaller volume can pass through the screen holes and contact with the aluminum alloy solution inside the shell; while the refining agent with a larger volume can be driven by the driving mechanism to drive the grinding mechanism to move on the screen plate, the refining agent with a larger volume is fully ground so that it can pass through the screen holes, so that the refining agent can be evenly dispersed on the surface of the aluminum alloy solution, which is convenient for the smooth progress of the aluminum alloy refining operation.

[0004] However, although the aluminum liquid refining device can grind refining agents of smaller volume, the screen plate inside it is prone to clogging, resulting in the refining agent remaining on the surface of the screen plate, making it impossible for the refining agent to fully enter the mixing drum, resulting in an error in the mixing ratio of the refining agent and the aluminum material, thereby reducing the quality of aluminum liquid refining.

[0024] The mixing drum 1 and the crushing drum 2 are connected by the support plate 3. The refining agent is added into the crushing drum 2 under the action of the feed pipe 4 and enters the mixing drum 1 through the sieve plate 5. The refining agent and the aluminum material can be fully stirred and mixed under the action of the stirring plate 8 inside the mixing drum 1, so that the aluminum liquid refining quality of the device is improved. The aluminum material enters the crushing drum 2, and the aluminum material with large lumps or particles is left inside the crushing drum 2.

The ground aluminum material is left inside the sieve plate 5 or enters the mixing drum 1. The anti-blocking plate 7 is rotated to effectively clean the holes inside the sieve plate 5 to avoid blockage of the sieve plate 5, thereby improving the processing efficiency of the device.

[0025] like Figure 1 and Figure 6 As shown, a cylinder cover 9 is provided on the top of the pulverizing cylinder 2, and the pulverizing cylinder 2 and the cylinder cover 9 are connected by positioning bolts. The feed pipe 4 is perpendicular to the cylinder cover 9. There are two cylinder covers 9, and a closing cover 10 is installed on the top of the cylinder cover 9 by rotating through a hinge.

[0026] The barrel cover 9 is driven by the crushing barrel 2. When the barrel cover 9 contacts the crushing barrel 2, the positioning bolts inside the barrel cover 9 are rotated to facilitate the positioning of the barrel cover 9. The feed pipe 4 is connected to the barrel cover 9. The closing cover 10 is flipped under the action of the hinge. When the closing cover 10 is opened, it is convenient to add aluminum material and aluminum refining agent into the crushing barrel 2.
