Description

Technical Field

[0001] This utility model relates to the technical field of dispersion preparation apparatus, and in particular to a dispersion preparation apparatus for disperse dyes. Background Technology

[0002] Disperse dye dispersions are stable systems formed by uniformly dispersing disperse dyes in a dispersion medium, and are widely used in textile printing and dyeing, coatings, and other fields. Existing disperse dye dispersion preparation equipment typically uses methods such as stirring and grinding to first mix the disperse dye with dispersant, solvent, etc., and then disperses the dye particles in the medium through mechanical force. After filtration and other processes, the dispersion is obtained. The basic principle is to rely on physical external force to break the agglomeration of dye particles and achieve uniform dispersion.

[0003] However, current disperse dye dispersion preparation devices on the market generally suffer from large dye particle size during disperse dye preparation, which affects the coloring and dyeing quality of the dye. Existing devices often cannot achieve integrated operation of dye dispersion and nanoscale preparation. The dispersion process and the nanoscale refining process usually need to be carried out step by step in different equipment. This not only increases the complexity of the process flow and leads to low production efficiency, but may also cause dye loss and contamination due to multiple material transfers. It is difficult to meet the modern industry's demand for high-quality and high-efficiency disperse dye dispersion preparation. To address these issues, we propose a disperse dye dispersion preparation device. Utility Model Content

The mixing and dispersion chamber 3 is provided with a dispersing and stirring component 9. The two drive motor units 6 drive the rotor shearing frame 8 and the dispersing and stirring component 9 to rotate respectively.

[0029] The beneficial effects of this solution are as follows: By providing an isolation distribution plate 2 inside the preparation carrier tank 1, the interior of the preparation carrier tank 1 can be divided into a mixing and dispersion chamber 3 and a nano-dispersion chamber 4. The disperse dye is mixed and prepared in the mixing and dispersion chamber 3, and then pressurized and guided by the pressurized flow guiding component 5 to be drawn into the nano-dispersion chamber 4. The nano-cutting component 7 and the rotor shear frame 8 disperse the nano-sized particles. The complete dispersion and refinement operation can be carried out in a single equipment and a single process operation, which improves the efficiency of dispersion preparation and production.

[0030] The top drive motor 6 drives the dispersing and stirring component 9 to rotate, stirring the dispersion liquid in the mixing and dispersing chamber 3. Then, the pressure guiding component 5 pressurizes and guides the liquid into the nano-dispersion chamber 4. The bottom drive motor 6 drives the rotor shearing frame 8, which rotates and shears the dispersion liquid in the nano-cutting component 7. This performs nano-level extrusion shearing, cutting the dispersion liquid particles into nano-sized particles, making them easier to dye fibers, improving color fastness, and resulting in excellent preparation quality. The device can complete the dispersion and refinement of the dispersion liquid in one integrated process, improving the efficiency of dispersion liquid preparation and production. It also has good dispersion and shearing effects and high dye processing quality.

[0038] Specifically, multiple nano-adhesive ends 71 ​​are arranged in a ring shape and nested sequentially, with cutting edges 72 evenly distributed on the nano-adhesive ends 71. Multiple rotor shearing blades 82 can stably squeeze and shear the seams of the nano-adhesive ends 71, facilitating nanoscale cutting and crushing of the dispersion. The multiple nano-adhesive ends 71 ​​and multiple rotor shearing blades 82 cooperate to squeeze the dispersion into the cutting edges 72 to complete the squeezing and shearing, resulting in good particle crushing effect and excellent shearing quality.

Multiple rotor shearing cutters 82 are evenly installed on the top of the rotating support frame 81 according to their size. The rotor shearing cutters 82 rotate and fit against the gap of the nano-cutting component 7.

[0040] Specifically, the rotating support frame 81 can support and fix multiple rotor shearing cutters 82. Running the rotating support frame 81 can drive multiple rotor shearing cutters 82, so that multiple rotor shearing cutters 82 can stably squeeze and shear the joint of the nano-adhesive end 71, which facilitates nano-level cutting and crushing of the dispersion. Multiple nano-adhesive end 71 and multiple rotor shearing cutters 82 cooperate to squeeze the dispersion into the cutting edge 72 to complete the squeezing and shearing, resulting in good particle crushing effect and excellent shearing quality.

[0041] Furthermore, a sealing oil seal 83 is provided at the joint between the rotating support frame 81 and the preparation support tank 1, and the rotating support frame 81 is driven to rotate by the drive motor unit 6 at the bottom.

[0044] Specifically, the drive motor 6 at the top drives the rotating frame 91 to mix and stir the inside of the mixing and dispersing chamber 3, ensuring stable mixing. At the same time, it drives the cleaning scraper 92 to scrape away dirt from the inner wall, achieving a cleaning effect.

[0045] How to use and how to work this device:

[0046] By providing an isolation distribution plate 2 inside the preparation carrier tank 1, the preparation carrier tank 1 can be divided into a mixing and dispersion chamber 3 and a nano-dispersion chamber 4. The disperse dye enters the preparation carrier tank 1 through the feed hopper 14, is mixed and prepared in the mixing and dispersion chamber 3, and is then pressurized and guided by the pressurizing and guiding component 5 to be drawn into the nano-dispersion chamber 4. The nano-cutting component 7 and the rotor shearing frame 8 disperse the nano-sized particles. The complete dispersion and refinement operation can be carried out in a single equipment and a single process operation, which improves the efficiency of dispersion preparation and production.

[0047] The mixing and dispersing chamber 3 is equipped with a dispersing and stirring component 9. The drive motor 6 at the top can drive the dispersing and stirring component 9 to rotate, so that the dispersion liquid in the mixing and dispersing chamber 3 is stirred and prepared. Then, the pressure guiding component 5 pressurizes and guides the liquid to be drawn into the nano-dispersing chamber 4. The drive motor 6 at the bottom drives the rotor shearing frame 8, which can be rotated and sheared in the nano-cutting component 7 to perform nano-level extrusion shearing on the dispersion liquid. This allows the particles of the dispersion liquid to be sheared into nano-sized particles, which are easier to dye fibers, improve color fastness, and produce excellent quality.

[0048] The discharge pipe 11 can discharge excess impurities or materials in the mixing and dispersion chamber 3. The pressure gauge 12 is used for pressure measurement. When the preparation liquid in the nano-dispersion chamber 4 is sufficient, the pressure can be directly measured by the pressure gauge 12 with high measurement accuracy. The switch control tube 13 can discharge materials in the nano-dispersion chamber 4 and the switch control is convenient. The discharge hopper 14 facilitates the entry of materials into the mixing and dispersion chamber 3. The operation is stable and the adaptability is good.

[0049] The pressurized flow guiding component 5 includes a connecting pipe 51 and a flow guiding pump body 52. ​​The connecting pipe 51 can guide the solution in the mixing and dispersion chamber 3 to the interior of the nano-dispersion chamber 4. The flow guiding pump body 52 plays the role of pressurization and flow guiding. When the nano-dispersion chamber 4 is full of solution, it can be detected by the pressure measuring gauge 12. The flow guiding pump body 52 stops the injection and the switch-close valve 53 controls the switching operation to prevent backflow and ensure stable operation.

[0050] The nano-cutting component 7 includes nano-adhesive ends 71 ​​and cutting blades 72. Multiple nano-adhesive ends 71 ​​are arranged in a ring shape and nested sequentially. The cutting blades 72 are evenly distributed on the nano-adhesive ends 71. The rotor shearing frame 8 includes a rotating support frame 81 and rotor shearing blades 82. The rotating support frame 81 can support and fix multiple rotor shearing blades 82. Running the rotating support frame 81 can drive multiple rotor shearing blades 82, so that multiple rotor shearing blades 82 can stably squeeze and shear the joint of the nano-adhesive ends 71, which is convenient for nano-level cutting and crushing of the dispersion. Multiple nano-adhesive ends 71 ​​and multiple rotor shearing blades 82 cooperate to squeeze the dispersion into the cutting blades 72 to complete the squeezing and shearing. The particle crushing effect is good and the shearing quality is excellent.

[0051] The dispersing and stirring component 9 includes a rotating frame 91 and a cleaning scraper 92. The drive motor 6 at the top drives the rotating frame 91 to mix and stir the inside of the mixing and dispersing chamber 3. The stirring is stable, and at the same time, the cleaning scraper 92 scrapes off dirt from the inner wall, achieving a cleaning effect. This allows the device to complete the dispersion and refinement of the dispersion liquid in one go, improving the efficiency of dispersion liquid preparation and production. It also has good dispersion and shearing effects and high dye processing quality.
