Description

Technical Field

[0001] The utility model relates to the technical field of fluorescent whitening agent production, in particular to a crystal mixing reaction device for fluorescent whitening agent production. Background Technique

[0002] Fluorescent whitening agents, also known as fluorescent dyes or white dyes, are special compounds that can emit blue or blue-violet fluorescence under ultraviolet light irradiation.

[0003] Its functions mainly include: Optical whitening effect: Fluorescent whitening agents can absorb invisible ultraviolet light in the light and then emit visible fluorescence. This fluorescence usually appears blue or blue-violet. Application fields: Fluorescent whitening agents are widely used in many industries, including but not limited to paper, plastics, leather, detergents, textiles, etc. Environmental friendliness: Some types of fluorescent whitening agents (such as CBS) are used in low amounts in detergents and are easily degradable. In domestic sewage after general treatment, the content of CBS can be greatly reduced. Safety: After years of research and experiments, fluorescent whitening agents have been proven to be non-irritating to the skin, will not cause skin allergies, and will not react with the skin.

[0004] Among them, when producing fluorescent whitening agents, a mixing reaction device is used to mix and react the raw material crystals of fluorescent whitening agents for the subsequent processing of fluorescent whitening agent raw materials.

Existing mixing reaction devices often have problems such as low mixing efficiency and slow reaction speed when mixing reaction materials. Especially in chemical reactions catalyzed by temperature, they cannot provide sufficient temperature support, resulting in poor reaction effects. Content of the Utility Model

A stirring motor 8 is fixedly installed in the middle of the upper end of the mixing reaction kettle 4. A stirring shaft 9 is fixedly installed at the lower end of the transmission shaft of the stirring motor 8. The upper end of the stirring shaft 9 is rotationally connected through a rotating shaft to the upper end of the mixing reaction kettle 4. Stirring rods 10 for stirring and mixing the crystals of the fluorescent whitening agent production raw materials inside the mixing reaction kettle 4 are fixedly installed on the outer surface of the lower end of the stirring shaft 9. The number of stirring rods 10 is several, which are symmetrically distributed in sequence from top to bottom on the outer surface of the lower end of the stirring shaft 9;

[0025] There are two support plates 11 fixedly installed at the front end of the support base 3, symmetrically distributed up and down at the front end of the support base 3. A support ring 12 is fixedly installed at the front end of the support plate 11, and the support ring 12 surrounds the outer curved surfaces of the upper and lower ends of the middle part of the mixing reactor 4 inside. A limiting ring rail 13 is fixedly installed inside the support ring 12, and a number of limiting rollers 14 are in rolling fit with the inside of the limiting ring rail 13, symmetrically distributed in sequence on the inside of the limiting ring rail 13.

The exhaust gas generated by the crystal mixing reaction of the fluorescent whitening agent production raw materials inside the mixing reactor 4 is discharged through the exhaust port 7 for centralized treatment. By controlling the driving motor 16 to start, when the driving motor 16 starts, it drives the transmission gear 17 to rotate. When the transmission gear 17 rotates, due to the meshing connection between the inner side of the transmission gear 17 and the transmission gear ring 20, a force is generated to drive the heating cylinder 15 to rotate. When the heating cylinder 15 rotates, it drives the electric heating tube 19 to rotate. When the electric heating tube 19 rotates, the crystals of the fluorescent whitening agent production raw materials inside the mixing reactor 4 are evenly heated, thereby increasing the mixing reaction efficiency of the fluorescent whitening agent production raw materials crystals while enabling the crystals of the fluorescent whitening agent production raw materials to be evenly heated.
