[0002] A photoinitiator, also known as a photosensitizer or a photo-curing agent, is a kind of compound that can absorb energy of a certain wavelength in the ultraviolet region (250 - 420 nm) or the visible light region (400 - 800 nm), generate free radicals, cations, etc., thereby initiating the polymerization and cross-linking curing of monomers.

[0003] During the preparation process of the photoinitiator, a decolorization process is required. The existing decolorization equipment generally decolorizes the photoinitiator solution through an activated carbon layer. After decolorization, the finished product is obtained through crystallization, washing, and drying, and then packaged and stored in the warehouse. However, the existing decolorization equipment needs to replace the decolorizing agent after working for a period of time, otherwise the decolorization effect will be affected. When replacing the decolorizing agent, the device needs to stop working, resulting in low production efficiency and being not conducive to the continuous production. In view of the above problems, the utility model provides a solution. Summary of the Utility Model

Detailed Embodiments

[0017] The following further describes the present utility model in detail with reference to the drawings. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Such as Figures 1-3As shown in the figure, a photoinitiator decolorization device includes a housing 1, a feed inlet 2, a liquid outlet 5, and feet 10. The feed inlet 2 is provided at the top of the housing 1. The cross-section of the housing 1 is a rectangular structure. A liquid distribution plate 6 and a decolorization plate 8 are installed inside the housing 1. The liquid distribution plate 6 is located above the decolorization plate 8. A liquid storage cavity 3 is formed between the upper part of the liquid distribution plate 6 and the housing 1. The liquid distribution plate 6 is provided with a number of evenly distributed liquid dripping holes 7. The lower end of the liquid dripping hole 7 is a liquid distribution nozzle protruding from the bottom surface of the liquid distribution plate 6. The number of the decolorization plates 8 is multiple. The bottom of each decolorization plate 8 is horizontally seated on a support base 11 inside the housing 1. An installation socket for inserting the decolorization plate 8 is provided on one side of the housing 1. A handle 9 is provided on one side of the decolorization plate 8 at the installation socket position. The handle 9 extends to the outside of the housing 1. The decolorization plate 8 includes a filter support net 19, a filter layer 20, and a decolorization layer 21 from bottom to top in sequence. The bottom cavity of the housing 1 is a liquid outlet cavity 4. The liquid outlet 5 is provided on the bottom side wall of the liquid outlet cavity 4. A valve 12 is installed on the liquid outlet 5. A decolorization cover 13 is installed at the outer end of the liquid outlet 5. An outer filter net 14, an outer filter layer 15, an adsorption layer 16, an inner filter layer 17, and an inner filter net 18 are installed at the outlet end of the decolorization cover 13 from outside to inside in sequence.

[0019] Further, the number of the liquid outlets 5 is multiple. A valve 12 and a decolorization cover 13 are installed on each liquid outlet 5. The liquid outlet that needs to replace the decolorization cover 13 can be closed through the valve 12.

[0020] Further, the outer filter net 14, the inner filter net 18, and the filter support net 19 are all metal wire meshes. The above filter nets play a framework role externally, restricting the adsorption and decolorization materials and filter materials inside to form a certain shape.

[0021] Further, the outer filter layer 15, the inner filter layer 17, and the filter layer 20 are all made of non-woven fabric. The non-woven fabric wraps the adsorption and decolorization materials in the above filter layer to prevent them from flowing with the liquid.

[0022] Further, the adsorption layer 16 and the decolorization layer 21 are both filled with activated carbon, and various adsorbents can also be selected according to the type of photoinitiator.

[0023] Further, the decolorization cover 13 is connected to the end of the liquid outlet 5 through a threaded structure. The threaded structure connection facilitates the disassembly of the decolorization cover 13 to replace the internal filter layer and adsorption layer.

[0024] Working principle: The photoinitiator liquid is added into the liquid storage chamber 3 from the feed port 2, and then distributed by the liquid distribution plate 6 and evenly flows downward to the decolorization tray 8. After the luminescent agent liquid is decolorized multiple times by the decolorization tray 8, it reaches the liquid outlet chamber 4 at the bottom and is discharged through the liquid outlet 5. When discharging, it is decolorized again through the decolorization cover 13. When it is necessary to replace the decolorization tray 8, just take out the decolorization tray 8 through the handle 9, replace the decolorization material inside, insert it, and then replace the next decolorization tray 8 in sequence. When replacing the decolorization cover 13, close the valve 12 on the corresponding liquid outlet 5 for replacement. After replacement, open the valve 12 again. During the replacement process, it does not affect the normal operation of the decolorization device, ensures the continuous operation of the decolorization device, improves work efficiency, and reduces the pollution caused by the intermediate transfer process.

[0025] This specific embodiment is only an interpretation of the present invention, and it is not a limitation to the present invention. After reading this specification, those skilled in the art can make modifications without creative contributions to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
