Description

Technical Field

[0001] The invention relates to aluminum continuous extrusion equipment and a method and device for online processing of process wastes thereof, and in particular to a continuous extrusion aluminum overflow processing device and a processing method. Background Art

[0002] The working principle of the existing continuous extruder is as follows Figure 1 As shown, after the aluminum rod (1) is pressed down by the compacting wheel (2), it is embedded in the wheel groove (4) and rotates together with the extrusion wheel (5) under the action of friction. There is an arc surface on the cavity (3) that matches the outer circumferential surface of the extrusion wheel. A small gap is maintained between the two arc surfaces during operation. During operation, the extrusion wheel rotates clockwise, while the cavity is fixed. There is a convex part (blocking block) on the cavity that extends into the groove of the extrusion wheel. When the blank rotates with the extrusion wheel to the position of the blocking block, the movement along the circumferential direction is blocked and plastic deformation occurs, changing the flow direction and entering the cavity. Due to the uninterrupted supply of the blank, a certain pressure is formed inside the cavity. Under the action of pressure, most of the billet is extruded through the die to form a product (6), and another small part of the billet is extruded from the gap between the cavity and the extrusion wheel to form overflow; when aluminum and aluminum alloy are extruded, the overflow adheres to the surface of the extrusion wheel and rotates with the extrusion wheel. When the overflow rotates to the position of the extruder scraper (8), it is peeled off to form overflow (7). Due to deformation and friction, the temperature of the overflow is between 400 and 500°C. The main problem currently exists is that the overflow is in the form of continuous strips and has a high temperature, which is not easy to collect and occupies a large space; at the same time, the operator needs to continuously handle the overflow, which consumes manpower and has high labor intensity.
