Supercritical fluid-assisted polymer processing device

The utility model discloses a supercritical fluid-assisted polymer processing device which can be used for realizing quick shearing and diffusing of supercritical fluid towards the inner part of the polymer under a molten state by virtue of a heating and shearing effect of the device, and assisting the processing and foaming of thermoplastic plastics and thermoplastic elastomer. The supercritical fluid-assisted polymer processing device comprises a chamber for bearing pressure, a shearing element, a multi-point gas inlet and cooling structure, a sealing structure, a supercritical fluid conveying device, a pressure release device, a pressure display device, a heating element and a temperature control device. The chamber is provided with the multi-point gas inlet structure for preventing blockage; and the chamber is further provided with the pressure display device and the pressure release device, so that the pressure release velocity is adjustable. The supercritical fluid-assisted polymer processing device has
