This utility model discloses a cooling device for a twin-screw extruder, comprising a cooling tank: a twin-screw extrusion body is transversely installed through the side wall of the cooling tank, a direct cooling assembly is arranged on the cooling tank, a cleaning assembly is arranged outside the twin-screw extrusion body, a filter plate is transversely installed in the cooling tank, and an anti-blocking assembly is arranged on the filter plate. The cooling device for a twin-screw extruder is provided with a U-shaped copper pipe, equipment and water spray nozzles. When the twin-screw extrusion body needs to be cooled, the cooling liquid filtered by the filter plate at the bottom inside the cooling tank is brought into the U-shaped copper pipe by starting the equipment, then cooled in a deep water well through the U-shaped copper pipe, and then the cooled cooling liquid enters each water spray nozzle through a pipeline. Water is sprayed outside the twin-screw extrusion body through each water spray nozzle, and the twin-screw extrusion body is directly cooled by flowing cold water, thus solving the problem of slow heat conduction in the above patent.
