[0002] Water-soluble anti-yellowing fluorescent whitening agents, as the name implies, are a type of whitening agent that can dissolve in water. They are mainly used to enhance or correct the whiteness of the object surface and improve the overall brightness of the object. Water-soluble fluorescent whitening agents are widely used in many industries and fields such as textiles, papermaking, detergents, plastics, coatings, inks, leather, anti-counterfeiting, and laser detection. In detergents, common fluorescent whitening agents include types such as EBF, which are widely used in fields such as water-based coatings, dyed textiles, foam rubber, and polymers;

[0003] The main functions of water-soluble anti-yellowing fluorescent whitening agents include: improving the washing effect: in detergents, the fluorescent whitening agent can make yellowed and aged clothes become white and bright as new, visually improving the washing effect of the detergent; improving the appearance of the washing product: the fluorescent whitening agent can also increase the whiteness of the washing powder powder or soap bar body, improving the appearance of the detergent product and enhancing the product grade; brightening and enhancing the color effect: on textiles and other objects that need to be whitened, the fluorescent whitening agent can significantly increase their whiteness and brightness, making the object look more vivid and bright.

The lower end of the stirring motor 4 is fixedly installed with a stirring shaft 5, and the stirring shaft 5 is rotationally connected to the middle of the upper end of the reactor main body 1 through a rotating shaft. At the bottom of the stirring shaft 5, there is fixedly installed a stirring paddle 6 for mixing and stirring the water-soluble anti-yellowing fluorescent whitening agent inside the reactor main body 1. The bottom of the reactor main body 1 is fixedly installed and communicated with a discharge pipe 7 for discharging the raw materials of the water-soluble anti-yellowing fluorescent whitening agent that have completed the mixing reaction inside the reactor main body 1. On the outer curved surface of the front end of the reactor main body 1, there are successively fixedly installed and communicated with an upper sampling pipe 8, a middle sampling pipe 9, and a lower sampling pipe 10 from top to bottom, so that the raw materials of the water-soluble anti-yellowing fluorescent whitening agent at different heights inside the reactor main body 1 can be discharged and sampled through the upper sampling pipe 8, the middle sampling pipe 9, and the lower sampling pipe 10. On the outer curved surface of the side end of the reactor main body 1, there is fixedly installed a transparent observation window 11, so that the reaction condition of the raw materials of the water-soluble anti-yellowing fluorescent whitening agent inside the reactor main body 1 can be observed through the transparent observation window 11. A temperature sensor is fixedly installed inside the reactor main body 1, so that the temperature inside the reactor main body 1 can be monitored through the temperature sensor;

[0024] On the upper side end of the reactor main body 1, a U-shaped support frame 12 is fixedly installed. At the upper end of the U-shaped support frame 12, a driving motor 13 is fixedly installed. At the lower end of the transmission shaft of the driving motor 13, a first sprocket 14 is fixedly installed. The outer end of the first sprocket 14 is connected by a chain to a second sprocket 15. In the middle of the second sprocket 15, a heat conduction pipe 16 is fixedly installed. The upper and lower outer curved surfaces of the heat conduction pipe 16 are respectively rotationally connected through a rotating shaft at the upper and lower side ends of the reactor main body 1. At the upper and lower openings of the heat conduction pipe 16, an upper rotating joint 17 and a lower rotating joint 18 are respectively installed.

The number of the dispersion pipes 19 is several, and they are symmetrically distributed with respect to the upper and lower outer curved surfaces in the middle of the heat conduction pipe 16.

[0025] Working principle: When in use, the utility model discharges the raw materials of the water-soluble anti-yellowing fluorescent whitening agent to be reacted and processed into the reactor main body 1 through the main feeding port 2 and the auxiliary feeding port 3. When the raw materials of the water-soluble anti-yellowing fluorescent whitening agent are discharged into the reactor main body 1, the stirring motor 4 is controlled to be turned on. When the stirring motor 4 is turned on, it will drive the stirring shaft 5 to rotate. When the stirring shaft 5 rotates, it will drive the stirring paddle 6 to mix and stir the water-soluble anti-yellowing fluorescent whitening agent, so as to realize the function of mixing and stirring the water-soluble anti-yellowing fluorescent whitening agent inside the reactor main body 1.

[0026] When the water-soluble anti-yellowing fluorescent whitening agent is subjected to mixing and stirring reaction, through the upper sampling pipe 8, the middle sampling pipe 9 and the lower sampling pipe 10, it is convenient to discharge and sample the raw materials of the water-soluble anti-yellowing fluorescent whitening agent at different heights inside the reactor main body 1.

The temperature inside the reactor main body 1 is monitored by the temperature sensor fixedly installed inside the reactor main body 1. When the temperature inside the reactor main body 1 is too high or too low, the temperature-adjusted water is discharged into the heat conduction pipe 16 and the dispersion pipe 19 along the upper rotating joint 17 through the external water supply pipe, so that the temperature-adjusted water exchanges heat with the raw materials of the water-soluble anti-yellowing fluorescent whitening agent inside the reactor main body 1 in the heat conduction pipe 16 and the dispersion pipe 19, and the heat-exchanged temperature-adjusted water is discharged through the lower rotating joint 18 and the external return water pipe, so as to realize the function of adjusting the temperature inside the reactor main body 1 while mixing and stirring the water-soluble anti-yellowing fluorescent whitening agent inside the reactor main body 1.

[0027] Meanwhile, by controlling the start of the driving motor 13, when the driving motor 13 is started, it will drive the first sprocket 14 to rotate. When the first sprocket 14 rotates, it will drive the second sprocket 15 to rotate through chain drive. When the second sprocket 15 rotates, it will drive the heat conduction tube 16 and the dispersion tube 19 to rotate. When the heat conduction tube 16 and the dispersion tube 19 rotate, it will accelerate the heat exchange effect between the temperature control water and the water-soluble anti-yellowing fluorescent brightening agent raw material inside the heat conduction tube 16 and the dispersion tube 19, thereby further facilitating the regulation of the temperature inside the reaction kettle body 1.
