Proofing dyeing cup for supercritical fluid dyeing and finishing

A proofing 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 high-pressure fluid delivery tube (7), 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 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, 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 inner bottom of the high-pressure dyeing cup body is in the shape of a concave circular arc, a medium outlet (10) being provided on a side wall of the high-pressure dyeing cup body at a position adjacent to the cup opening, 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;
• the high-pressure fluid delivery tube is connected with a lower end of the high-pressure dyeing cup seal cover, and the high-pressure fluid delivery tube being vertically suspended in the high-pressure dyeing cup body;
• and
• the proofing dyeing cup for supercritical fluid waterless dyeing 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.
