Description

TECHNICAL FIELD

[0001] The application relates to the technical field of liquid disperse dye preparation, in particular to an intelligent production equipment and production method for liquid disperse dye with high strength and high stability. BACKGROUND

[0002] In the textile printing and dyeing industry, liquid disperse dye has become the first choice for dyeing synthetic fibers such as polyester and polyamide due to its excellent coloring performance, good light and washing fastness, and good affinity for synthetic fibers. Compared with traditional powder disperse dye, liquid disperse dye has the advantages of rapid dissolution / dispersion, simple operation, low pollution emission, and has been widely popularized in industrial production. However, with the increasing requirements of high-end garment fabrics and functional textiles on color uniformity and batch stability, the traditional disperse dye production process has the following technical bottlenecks: (1) uneven dispersion problem: conventional liquid disperse dye production usually uses high-speed mechanical stirring (such as paddle, sand mill or colloid mill) to mix the dye with the water phase and the dispersant. However, this method is difficult to completely destroy the agglomeration phenomenon between the dye particles, resulting in uneven distribution of the dye in the solvent, affecting the coloring uniformity and stability of the final product, especially for high-concentration disperse dye systems, the system viscosity increases significantly, the van der Waals force between particles increases, and mechanical shear is difficult to completely disperse the agglomerated particles, which is easy to form local high-concentration "dead zone" in the mixing container or re-aggregate along the container wall-stirring paddle gap, eventually leading to wide particle size distribution, uneven color, and large coloring fastness fluctuation between batches; (2) low surfactant addition efficiency: the existing process usually uses one-time input of surfactant, which cannot locally strengthen the wetting of the agglomerated dye generated or migrated during the production process, resulting in that part of the dye is not fully wrapped, and is easy to precipitate or flocculate during storage, reducing the product stability; (3) lack of process monitoring: the current production mainly relies on manual experience to judge the mixing endpoint, and lacks quantitative indicators. Although optical detection method can be used for uniformity evaluation, the dye is easy to adhere to the detection window during stirring, resulting in signal drift.

[0003] To solve the above problems, the prior art such as patent CN116102902A uses vinyl monomers and silane monomers to prepare an emulsion, and mixes to form a high molecular emulsion as a dispersion stabilizer, cooperates with sealed high-speed shearing and rotary distillation concentration to form a high-concentration liquid dispersed dye. Although this method improves the dye concentration and improves the storage and transportation performance to some extent, the high molecular / silane emulsion as a whole dispersant is difficult to penetrate deeply into the agglomerated dye inside, only forms an adsorption layer on the surface of the agglomerate, and has no effect on the internal unwetted particles, and the high-temperature and high-pressure shearing and rotary concentration process accelerates the system desolventization and concentration, but does not implement directional regrinding or local intensive shearing on the agglomerate, and the agglomerate core is difficult to be completely destroyed, and the problem that the dispersed dye cannot be fully contacted with the dispersion stabilizer inside after agglomeration cannot be fully solved in the above high-concentration liquid dispersed dye process; therefore, it is urgent to develop a production method integrating efficient dispersion, intelligent control and self-cleaning function to meet the stringent requirements of high-end textile printing and dyeing industry on dye quality.

In the process of mixing the solvent with the surfactant and the disperse dye to prepare the liquid disperse dye by the rotation of the stirring blade 506, due to the high-speed rotation of the stirring blade 506, a vortex will appear in the center of the liquid surface, and the disperse dye located in the center of the vortex will be fully mixed with the solvent. At this time, the distance between the vortex and the cover 3 is observed by the distance measuring module 701, and then the distance between the vortex and the bottom of the inner wall of the mixing bucket 1 is calculated. At this time, the extension cylinder 707 is moved upward by starting the electric telescopic rod 705 to push the connecting ring 706, so that the upper end of the extension cylinder 707 moves to the lower side of the liquid surface by 5 cm. Then start the first water pump 708, at this time the first water pump 708 will extract the disperse dye in the center of the liquid surface downward through the upper end of the extension cylinder 707, and then enter the inside of the fixed cylinder 703, and then be discharged through the gap between the outer wall of the fixed cylinder 703 and the inner wall of the fixed disc 503 and the outer wall of the friction plate 704. Since the inside of the fixed cylinder 703 is fixedly connected with the inner wall of the mixing bucket 1 through the fixed stake 702, the outer wall of the friction plate 704 rotates at high speed relative to the fixed cylinder 703 and the fixed disc 503, and since the outer wall of the friction plate 704 is rough, the dye and liquid passing through the gap between the inner wall of the fixed disc 503 and the outer wall of the friction plate 704 are subjected to strong extrusion and turning friction, so that the inner and outer surfaces of the disperse dye are fully contacted and wetted by the solvent. And since the agglomerated dye will also move to the upper side of the vortex in the vortex due to the influence of the vortex, it will be extracted, and then be ground and dispersed by the inside of the fixed disc 503, so that the agglomeration phenomenon in the mixing process can be avoided. And since another part of the surfactant is injected into the water storage box 801 through the liquid inlet pipe 802, the second water pump 803 extracts the surfactant and discharges it into the upper side of the fixed stake 702 through the liquid outlet pipe 804. During the operation of the second water pump 803, whether it is idling is detected by the control module 4. When the second water pump 803 idles, it means that the second water pump 803 has emptied the surfactant in the water storage box 801, and the second water pump 803 is turned off immediately. After the surfactant enters between the fixed disc 503 and the outer wall of the fixed cylinder 703, it contacts with the solvent rich in disperse dyes that have not been fully mixed, and is fully mixed when being discharged upward through the fixed disc 503, thereby achieving the effect of adding surfactant to the solvent containing disperse dyes, so that the surface of the disperse dyes is more efficiently wetted.

The laser emitting module 806 can output light to the laser receiving module 807, the laser receiving module 807 receives and records the brightness of the received light, and transmits the brightness fluctuation to the control module 4, when the brightness fluctuation is large and frequent, it indicates that the distribution of the disperse dye in the solvent is not uniform, when the brightness remains stable for a period of time, it indicates that the disperse dye has been fully mixed with the solvent, and then the electric telescopic rod 705 is started to retract the extension cylinder 707, so that the extension cylinder 707 moves away from the lower side of the liquid surface, at the same time, the control module 4 detects whether the second water pump 803 is stopped, if the second water pump 803 has not stopped, the surfactant is continuously emptied, in the process of descending of the extension cylinder 707, the rubber ring 809 is pushed downward, and then the rubber ring 809 moves to the inside of the transparent ring 805, in this process, the rubber ring 809 wipes the inner wall of the transparent ring 805, so that the dye adhered to the inner wall of the transparent ring 805 is scraped off and washed away, and the rubber ring 809 shields the inside of the transparent ring 805, preventing the dye from polluting the transparent ring 805 and affecting the detection result of the laser receiving module 807, so as to achieve real-time control of the mixing effect.

[0017] The application integrates a movable dispersion mechanism and a directional extraction mechanism in a traditional high-speed stirring device, uses a distance measuring module to accurately position the vortex center of the liquid surface and drive an electric telescopic rod to drive an extension cylinder, extracts the dye aggregates formed during mixing directly from the vortex on the liquid surface to the grinding area formed between the fixed disc and the friction plate, and performs high-strength extrusion and overturning friction to completely break the aggregation core and realize comprehensive wetting of the inner and outer surfaces.
