Description

Technical Field

[0001] This utility model relates to the technical field of filtration and impurity removal equipment, specifically a multi-stage filtration and impurity removal equipment for aluminum alloy smelting. Background Technology

[0002] Aluminum alloys, which are based on aluminum and contain a certain amount of other alloying elements, are a type of light metal material. During the smelting and casting of aluminum alloys, the aluminum alloy is smelted into a hot liquid. Impurities in the aluminum alloy liquid need to be removed to prevent them from affecting the hardness of the aluminum alloy when it is cast into an item. Impurities are filtered through a multi-stage filtration box to ensure that the hardness of the item is appropriate when the aluminum alloy liquid solidifies and is cast into an item, thereby ensuring the quality of the product.

[0003] For example, CN220495738U discloses a multi-stage filter box for aluminum alloy smelting, belonging to the field of aluminum alloy smelting. It includes a box body, with a filter tank fixedly connected inside. One end of the filter tank is fixedly connected to a liquid inlet that penetrates the box body. A primary filter layer is fixedly connected inside the filter tank, with a primary filter plate at the bottom of the primary filter layer, tightly fitted to the bottom of the primary filter layer. A heating module is fixedly connected to the bottom of the filter tank. A secondary filter layer is fixedly connected inside the filter tank, with a sliding groove inside the secondary filter layer. A secondary filter plate is slidably connected inside the sliding groove. An outlet is fixedly connected to the other end of the filter tank, penetrating the box body. The heating module evenly preheats the filter box and filter plate to near the temperature of molten aluminum, removing moisture and helping the filter plate pores shrink in advance, preventing partial pore blockage due to thermal shrinkage during filtration.

[0004] While the aforementioned patent can help preheat and shrink the filter plate pores in advance to prevent partial pore blockage caused by thermal shrinkage during filtration, the existing multi-stage filter box does not have a temperature monitoring structure, making it difficult to monitor the temperature of the aluminum alloy raw material solution inside the filter box in real time. This can easily lead to quality problems due to temperature fluctuations, reducing its practicality. Utility Model Content
