Mobile dyeing cup for supercritical fluid dyeing and finishing

A mobile dyeing cup for supercritical fluid waterless dyeing and finishing, comprising a high-pressure dyeing cup body (6), a high-pressure dyeing cup seal cover (4), a first high-pressure pipe (8), a second high-pressure pipe (9), a first high-pressure stop valve (1) and a second high-pressure stop valve (5), wherein:

• the high-pressure dyeing cup seal cover movably covers an upper cup opening of the high-pressure dyeing cup body, one end of the first high-pressure pipe being connected with an upper end of the high-pressure dyeing cup seal cover and being in communication with the high-pressure dyeing cup body, the other end of the first high-pressure pipe being connected to an external gas source or filling system, and the first high-pressure stop valve being mounted on the first high-pressure pipe;
• the bottom of the high-pressure dyeing cup body is in the shape of a circular arc, a medium outlet (10) being provided at the lowest portion of the circular arc bottom of the high-pressure dyeing cup body, one end of the second high-pressure pipe being connected at the medium outlet, the other end of the second high-pressure pipe being connected to an external separation and recycling system, and the second high-pressure stop valve being mounted on the second high-pressure pipe;
• a perforated baffle (7) is fixedly disposed in the high-pressure dyeing cup body, and the perforated baffle being located on a chord of the circular arc bottom of the high-pressure dyeing cup body;
• the mobile dyeing cup for supercritical fluid waterless dyeing and finishing further comprises a wireless integrated pressure and temperature sensor (2) and a safety valve (3), the wireless integrated pressure and temperature sensor being mounted on the first high-pressure pipe or the second high-pressure pipe, and the safety valve being mounted on the first high-pressure pipe or the second high-pressure pipe;
• both the wireless integrated pressure and temperature sensor and the safety valve are mounted on the second high-pressure pipe, a four-way connector (12) being mounted on the second high-pressure pipe between the medium outlet and the second high-pressure stop valve, and the wireless integrated pressure and temperature sensor and the safety valve being mounted at two opposite joints of the four-way connector respectively;
• the perforated baffle is made of fluorine coated stainless steel or a tetrafluoride material, and the perforated baffle has a pore size of 0.01 to 2 cm;
• and
• an inner surface of the high-pressure dyeing cup body is coated with polytetrafluoroethylene.
