Reaction kettle device for production of nylon dyeing acid-releasing agent

Abstract

The invention discloses a reaction kettle device for production of a nylon dyeing acid-releasing agent. The reaction kettle device comprises a kettle body, a stirring shaft, two stirrers, a motor, two material drip adding pipes and a material feeding pipe. The stirring shaft is arranged in the kettle body and rotatably connected to a reaction kettle cover, and the motor which is a driving motor is arranged at the top end of the stirring shaft; the two stirrers including an upper frame stirrer and a lower propeller stirrer are mounted on the stirring shaft in the kettle body; the material feeding pipe and the two material drip adding pipes are arranged on the reaction kettle cover, and the two material drip adding pipes are positioned on two sides of the stirring shaft respectively; a discharging pipe is arranged at the bottom of the kettle body, an annular jacket is arranged outside the kettle body, the bottom of the annular jacket is provided with a water inlet, and one side of the upper end of the annular jacket is provided with a water outlet. By the design that the stirrers in two layers are mounted on the stirring shaft, vertical circulation of materials in the kettle can be effectively promoted; by additional arrangement of spray heads at openings of the material drip adding pipes, material scattering speed can be effectively increased to shorten reaction time while energy consumption is effectively reduced, solvent evaporation is avoided in production, surrounding environment pollution is avoided, and product production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and in particular relates to a reactor device for nylon dyeing acid release agent provided by the application of textile dyeing auxiliaries. Background technique [0002] Nylon dyeing acid release agent has the advantages of high strength, good elasticity, good wear resistance, mildew and moth resistance, etc. It is mainly used in the field of nylon fiber in the textile industry. After the product diffuses into the fiber, it can also form with NH3 Ionic bonding, the pH value of the dye bath has a great influence on the dyeing of acid dyes. Due to the different pH values, the amount of H+ adsorbed by the fibers changes greatly, so the faster the dyeing rate of dyeing nylon, the higher the pH value. In this way, while ensuring a high balance dyeing percentage, it can reduce the initial dyeing rate, further improve the uniformity and stability of dyeing, and improve the product quality, so the mark...
