Description

Technical Field

[0001] This utility model relates to the field of decolorizing devices for optical resins, and more specifically, to a decolorizing device for optical resins. Background Technology

[0002] Optical resins are widely used in lenses, optical discs, optical fibers, architecture, and precision lenses. Diethylene glycol dicarbonate allyl ester and its oligomer optical resin (ADC) is one such optical resin material. As a raw material for optical resin lenses, ADC has particularly high requirements for color and requires a decolorization process. The decolorization process of ADC has the disadvantages of large amount of decolorizing agent used, high cost, and large environmental impact.

[0003] In existing technologies, the decolorization of optical resins requires the injection of a decolorizing agent into a reaction vessel. For example, patent application CN 117486721 A discloses a decolorization process for diethylene glycol dicarbonate allyl ester and its oligomeric optical resins. The process involves: adding crude ADC and pretreated decolorizing agent into a decolorization vessel at once, heating and stirring to a predetermined temperature and holding for a period of time, then vacuum dehydrating and collecting the solution from a filter to complete the ADC decolorization. This invention employs the ADC decolorization process, pre-treating and regenerating the wood fiber activated carbon used for decolorization for recycling. This can reduce the unit consumption by more than 90%, significantly reducing decolorization costs and the amount of solid waste emitted into the environment.

[0004] According to existing technology, in the optical resin decolorization reactor, the stirring mechanism is the mechanism to enhance the reaction. However, in the existing technology, the stirring mechanism is simple, the stirring position is constant during stirring, and the stirring is not comprehensive. Utility Model Content

Stirring blades are fixedly connected to the outer end surface of the rotating disks. A spring is sleeved on the lower outer surface of the drive shaft.
