Description
Technical Field
The invention belongs to the technical field of metal drawing oil filtration, and particularly relates to a filtration treatment system and a filtration treatment method for drawing oil containing aluminum slag.
Background
The aluminum conductor has the characteristics of small specific gravity, high conductivity, easy processing and the like, and is widely applied as a conductive material in the wire and cable industry. Because the aluminum conductor is extruded and processed into the form of an aluminum rod with the thickness of about 8mm by adopting a casting method during primary processing, the aluminum rod is not suitable for the application of the conductor in the electric wire and cable, and the aluminum rod is required to be drawn by drawing dies with different sizes to obtain an aluminum wire with a proper specification and then twisted by a plurality of aluminum wires to be suitable for the conductor in the electric wire and cable. In the metal wire drawing process, the mode of gradually reducing the outer diameter of the metal material through wire drawing dies with different sizes is adopted. During the wire drawing process, the metal material is extruded and deformed when passing through the wire drawing die, and a large amount of heat is generated. In order to reduce the large amount of heat generated by the metal material in the drawing process and prevent the wire drawing die from being overheated and locked by the wire drawing material, a large amount of cooling liquid is required to cool the wire drawing die. Therefore, in the process of drawing the thick aluminum rod into the thin aluminum wire, a large amount of cooling liquid is needed to cool the wire drawing die so as to prevent the aluminum rod from being locked at the position of the wire drawing die opening due to overheating. In order to ensure good passing property between the aluminum material and the wire-drawing die, generally, the cooling liquid adopts oily wire-drawing oil, so that the wire-drawing die can be cooled and the gap between the wire-drawing die opening and the aluminum conductor can be effectively lubricated.
However, because the aluminum material has poor mechanical strength and is brittle, after a long wire drawing process, a large amount of aluminum powder residues are mixed in the wire drawing oil, so that a large amount of aluminum powder residues are generated in the wire drawing process, and the following defects are caused: 1) the aluminum powder residue and the wire drawing oil form a solid-liquid mixture, and the solid-liquid mixture cannot precipitate in the repeated use process, so that the quality of the aluminum wire after wire drawing is influenced: 2) a small amount of aluminum powder residues are attached to the surface of the aluminum rod and pass through the wire drawing die, so that the surface of the drawn aluminum wire is uneven or has scale-like lines, the quality of the aluminum wire is seriously influenced, and the quality of a wire and cable product is further influenced. Because the wire drawing oil is an expensive oily substance which has large influence on the environment and is not easy to decompose, the direct abandonment of the wire drawing oil containing aluminum powder is neither economical nor environment-friendly, so that the aluminum powder residues in the wire drawing oil must be separated by a proper way, the wire drawing oil can be recycled, and the surface quality of the aluminum wire is not influenced.
