Abstract (en)

[origin: EP3708350A1] An extrusion separation and purification device, comprising an extrusion separation device body (100) and a purification device (200). The purification device comprises a material trough (7), a screw shaft (8), a motor (9), and a reduction box (10). An inner part of the material trough along the length direction of the material trough is provided with a sieve plate (16), the sieve plate divides the interior of the material trough into an upper chamber (18) and a lower chamber (19), and the sieve plate is provided thereon with a plurality of through holes (17). The screw shaft is rotatably arranged in the upper chamber. A rotating shaft of the motor is connected to a power input shaft of the reduction box, and a power output shaft of the reduction box is connected to one end of the screw shaft. One end of the material trough is provided with a first discharge port (23) that communicates with the upper chamber, and the other end of the material trough is provided with a second discharge port (24) that communicates with the lower chamber. A discharge port of the extrusion separation device body is located above a notch of the material trough. The aforementioned extrusion separation and purification device improves dry-wet separation efficiency and may effectively remove impurities in wet component materials.
