Description

Technical Field

[0001] This utility model relates to the field of aluminum liquid quality testing technology, and more specifically, to a device for testing the quality of recycled aluminum liquid from waste aluminum. Background Technology

[0002] In aluminum casting production, the quality of the molten aluminum alloy before pouring directly affects the quality of the aluminum castings. Under the premise of ensuring the aluminum alloy composition and pouring temperature, pre-furnace inspection is an important means to control the melting process and ensure the quality of aluminum castings.

[0003] Waste aluminum is often combined with other metals such as iron and steel for construction. In this way, the molten aluminum produced by recycling will inevitably contain a large number of impurities. When there is too much of a certain heat-resistant metal in a furnace, these impurities in the molten aluminum will affect the quality of the final aluminum products. In some precision fields, the lack of product quality can bring great hidden dangers.

[0004] A search revealed that Chinese patent CN211292883U discloses a quality testing device for recycled aluminum liquid. The waste aluminum solution is separated from impurities by the high-speed rotation of the filter screen in the pre-filter cartridge. After being exported to the testing tank, the pressure sensor provides feedback, which is displayed on the display module. If the value meets the requirements, the aluminum liquid is considered excellent. Aluminum liquid with values ​​fluctuating within a certain range can also be used. If the value deviation is too large, it is introduced into a precision separation device for fine separation and processing before quality inspection. This equipment is easy to set up, highly adaptable, cost-controllable, and effective, making it suitable for widespread application.

[0005] In actual use, the above-mentioned waste aluminum recycling liquid quality testing device separates impurities through a single filter screen rotating at high speed. However, the high-speed rotation of the filter screen can easily cause it to break. The broken filter screen cannot effectively intercept impurities, thereby reducing the filtration efficiency.

A second filter barrel is fixedly connected inside the first filter barrel. Two connecting rods are fixedly connected to the outer side of the first filter barrel. The connecting rods are fixedly connected to the top of the filter tank by bolts.

[0008] By adopting the above technical solution, double-layer filtration can be achieved. After the aluminum liquid is initially filtered, it is then finely filtered again, which helps to improve the filtration efficiency.

[0009] As a further description of the above technical solution: the mixing mechanism includes a variable frequency motor, which is fixedly connected to the top of the detection tank. A first rotating rod is fixedly connected to the output end of the variable frequency motor. Multiple first spiral blades are fixedly connected to the outside of the first rotating rod.

The second rotating rod is rotatably connected to the inside of the fixed cylinder.

[0010] By adopting the above technical solution, the aluminum liquid can be fully mixed in the testing tank, ensuring that the components in the aluminum liquid are evenly distributed.

[0011] The technical effects and advantages of this utility model are as follows: 1. By setting up a filtration assembly, compared with the prior art, the first filter barrel and the second filter barrel are used to filter impurities in the aluminum liquid. Multiple first and second scrapers can scrape the inner walls of the first and second filter barrels, thereby reducing the adhesion of impurities in the aluminum liquid and preventing impurities from accumulating on the first and second filter barrels. This helps to maintain the filtration efficiency of the first and second filter barrels and ensures that the aluminum liquid can pass through the first and second filter barrels smoothly. 2. By setting up a mixing mechanism, compared with the existing technology, the aluminum liquid can be fully mixed in the detection tank by rotating and stirring the first spiral blade and two second spiral blades inside the detection tank, ensuring that the components in the aluminum liquid are evenly distributed, reducing detection errors caused by uneven aluminum liquid composition, and improving detection accuracy.
