Description

Technical Field

[0001] The utility model relates to the technical field of supercritical dyeing equipment, in particular to a supercritical mixed fluid dyeing device. Background Art

[0002] A supercritical fluid is a fluid state above its critical temperature and critical pressure. In this state, the fluid's density and solubility lie between those of a gas and a liquid, resulting in unique solubility characteristics. The most commonly used supercritical fluid is supercritical carbon dioxide (SC-CO2), due to its safety and relatively low cost at room temperature and pressure. In this supercritical state, the fluid can effectively penetrate the interior of the material, providing a uniform dyeing effect. Dyes or pigments in supercritical fluids have high solubility and react well with the fibers or matrix of the material, achieving deep dyeing. These fluids are used to maintain a sealed environment in the supercritical state, typically subject to high pressure. They are used to heat the fluid to a supercritical state.

[0003] The prior art has the following defects or problems: The prior art publication number is: CN206015309U discloses a dye kettle for supercritical CO2 anhydrous dyeing, including a dye kettle tank body and a dye cylinder in the dye kettle tank body, the dye cylinder includes a cylindrical shell and a chassis, the chassis is arranged at the lower end of the cylindrical shell, and diversion holes are evenly distributed on the chassis. At least 3 dye separation channels are vertically arranged on the chassis, and the dye separation channels are formed by a partition vertically fixed on the chassis and the cylindrical shell. A dye net for placing dye is arranged at the bottom of the dye cylinder above the chassis, a filter membrane is arranged on the top of the dye cylinder, and a protective net is arranged above the filter membrane.

[0004] During use, the above-mentioned equipment uses a dye separation channel to isolate different dyes in the same dye cylinder, so that the supercritical CO2 anhydrous dyeing equipment can dye multiple colors at a time, reduce the uneven dyeing phenomenon that occurs during the anhydrous dyeing process, and achieve the purpose of preventing various dyes from contaminating each other and controlling the dye dosage.

[0005] The structure of the dye kettle described above does not have a structure for adjusting the pressure in the device, which may easily lead to excessive pressure and cause certain safety hazards. In addition, it does not have the effect of fully mixing the internal fluid during the dyeing process. Therefore, a supercritical mixed fluid dyeing device is proposed to address the above shortcomings.
