When the reaction tank body 1 of this structure adds dye and solvent into the interior through the feed port at the top for reaction, the driving motor 2 can stir the dye and solvent by driving the stirring shaft 3 to rotate, and when the stirring shaft 3 rotates, it will synchronously drive a plurality of slow-flow rings 4 to rotate, and when the slow-flow ring 4 rotates, it can The dye and the solvent are efficiently stirred, and the falling speed of the dye and the solvent can be delayed. At the same time, when the circulating pump 7 is started inside the arch seat 5, the material can be sucked in through the suction pipe 8 and refluxed from the discharge pipe 6 to the upper end of the reaction tank body 1 to form a material circulation, so that the dye and the solvent are more effectively in continuous contact during the circulation flow, further prolonging the action time, improving the reaction uniformity, and reducing energy consumption. Bolt paddles 9 are fixed on both sides of the middle of the stirring shaft 3 through support rods, and the bolt paddles 9 correspond to the vertical surface of the side corresponding to the arch seat 5. When the material inside the reaction tank body 1 passes through the two arch seats 5, the material inside the reaction tank body 1 is formed between the two arch seats 5. When the channel is formed, the bolt paddle 9 can cooperate with the stirring shaft 3 to rotate to stir the material more effectively, effectively increase the contact area between the dye and the solvent, thereby accelerating the dissolution rate. The stirring shaft 3 and the corresponding position of the slow flow ring 4 are fixedly sleeved with a sleeve 10, and a plurality of mixing plates 11 are connected around the outer wall of the sleeve 10 and the inner wall of the slow flow ring 4. The connection between the mixing plate 11 and the outer wall of the sleeve 10 and the inner wall of the slow flow ring 4 is welded and fixed, and the inner wall of the mixing plate 11 is evenly welded and fixed with a plurality of support pieces 12. When the material falls into the rotating slow flow ring 4, a part of it will directly fall into the mixing plate 11. The interior of the mixing plate 11 is in contact with a plurality of supporting pieces 12, so that the slow flow ring 4 can more effectively stir the material through the plurality of mixing plates 11, and also play a certain degree of slow flow effect, so as to achieve the effectiveness of the interaction between the dye and the solvent. The gaps formed between the mixing plates 11 are provided with stirring pieces 13, and the stirring pieces 13 are in an arc-shaped structure.

[0018] Working principle: When using the reaction device of disperse dye solvent, first add the material into the reaction tank body 1 through the two feed ports on the top of the reaction tank body 1, and then start the drive motor 2. When the drive motor 2 is driven, it will drive the stirring shaft 3 to rotate inside the reaction tank body 1. When the stirring shaft 3 rotates, it will also drive several slow flow rings 4 and bolt paddles 9 to rotate synchronously. In this way, when the falling material enters each rotating slow flow ring 4, a part of it will directly fall into the mixing plate 11 and several supporting pieces 12. The material is stirred by a group of slow-flow rings 4 at the upper end of the stirring shaft 3, and a part of it falls into the gap formed between the mixing plates 11 and contacts the stirring blades 13. When the material is stirred by a group of slow-flow rings 4 at the upper end of the stirring shaft 3, it will fall into the top of the arch seat 5. The arch seat 5 uses several guide grooves 14 on the top to concentrate the material to fall into the channel formed in the middle. At this time, the bolt paddle 9 will stir the material more fully. When the material is finally stirred by a group of slow-flow rings 4 at the lower end of the stirring shaft 3 and falls into the bottom layer inside the reaction tank body 1, the circulation pump 7 is started. When the circulation pump 7 is started, the material can be sucked in through the suction pipe 8 and refluxed from the discharge pipe 6 to the upper end of the reaction tank body 1 again to form a material circulation. In this way, the interaction effect between the dye and the solvent will be better, and the reaction rate will be faster, thereby completing a series of tasks.
