[0024] Reference Figures 1-4During overall operation, aluminum dross and other impurities generated during filtration can easily clog the filtration structure, resulting in high replacement costs and inconvenient disassembly. The frame 1 and the primary filter tank 603 are connected by bolts. The support frame 602 is connected by bolts to the electrical control box 601, the tertiary filter tank 604, the secondary filter tank 605, the heating tank 606, the vacuum separator 607, and the cooler 608.

By filtering aluminum dross and other impurities, the cost of subsequent processing steps can be reduced.

[0025] Working Principle: The oil filtration equipment for electrolytic aluminum transformers first extracts the oil from the transformer using an oil pump and sends it to the primary filter tank 603 for preliminary filtration to remove large particulate impurities. Subsequently, the oil is heated in a multi-stage infrared or conventional heating tank 606 to increase the temperature and facilitate the subsequent evaporation of moisture and gases. The heated oil then enters the vacuum separator 607, where, under vacuum, the oil forms a mist and film, significantly increasing the contact area between the oil and the vacuum. This allows the moisture in the oil to rapidly vaporize under high heat, high vacuum, and large surface area conditions and be discharged through the vacuum system. The evaporated water vapor and other gases are cooled and dehumidified before entering the condenser for further cooling. The condensate is collected and discharged. The treated, dried oil is then filtered and discharged from the oil outlet, completing the entire oil purification process. The frame 1 is bolted to the cabinet door 2 and the top-hinged door 3, and bolted to the cooling fan 4. A solenoid valve is installed on one side of the cooling fan 4. The frame 1, the top-hinged door 3, and the hydraulic rod 5 are connected... The rotating base connection, along with the enclosure door 2 and multiple sets of upward-opening doors 3, facilitates easy opening from all directions during maintenance, making operation convenient. The cooling fan 4, equipped with a solenoid valve, can be adjusted to maintain internal airtightness and air circulation. The frame 1 and primary filter tank 603 are bolted together. The support frame 602 is bolted together with the electrical control box 601, tertiary filter tank 604, secondary filter tank 605, heating tank 606, vacuum separator 607, and cooler 608. The end cover 6032 is bolted together with the primary filter tank 603. The filter cylinder 6038 and primary filter tank 603 are connected via a sleeve. The clamping sleeve 6036 is connected to the tail cover 6035 and primary filter tank 603 via a sleeve and secured with a tightening bolt 6037. The detachable primary filter tank 603 allows for rapid separation of aluminum slag-containing liquid, improving production efficiency, reducing energy consumption and environmental pollution. Filtering aluminum slag and other impurities reduces the cost of subsequent processing steps.
