The invention relates to a barrel of a parallel twin-screw extruder, comprising multiple cylinder sections. The inner cavity of each cylinder section is provided with a double-barrel extrusion flow channel, and connecting flanges are arranged at both ends. A spiral flow channel for cooling medium circulation is formed inside the cylinder wall, and liquid inlet and outlet mechanisms communicated with the spiral flow channel are installed at two ends of each cylinder section. With optimized sealing and connection structures, the barrel realizes effective sealing at joints through the expansion fit of sealing films and annular extrusion airbags. The connection operation is simple and labor-saving; automatic sealing can be completed during flange locking without additional power supply.
