Description

Technical Field

[0001] The present application relates to the technical field of zinc powder filtration, and in particular to a zinc powder removal filtration device for ultraviolet absorber production. Background Art

[0002] The zinc powder removal filtration device in the production process of ultraviolet absorbers is an important link in the production process. It is mainly used to remove zinc powder and its by-products from the reaction mixture after the reduction reaction or similar steps to ensure the purity and quality of the product. The treated zinc powder and its by-products are collected and further processed or disposed of as needed.

[0003] After searching, the publication number: CN211836703U announced a filtering device for the production of ultraviolet absorbers. The raw material liquid is injected into the box through the input pipe. The raw material liquid is first filtered through the primary filter plate and enters the stirring bin. The raw material liquid is fully stirred to separate the impurities. Then the solenoid valve is opened to discharge the raw material liquid downward, pass through the fine filter plate, and then pass through the leak plate for precipitation. The funnel mouth of the leak plate is a funnel structure to prevent the sediment from turning over. After a long period of precipitation, the valve on the drain pipe is opened to discharge the upper layer of liquid into the filter bin and flow into the filter chamber on both sides of the filter bin. A dispersion plate is set in the filter chamber. The dispersion plate is a pore structure. Then it passes through the coke layer, lime layer, and cotton yarn layer in turn and is discharged from the outlet, absorbing oil and particulate matter in the process.

[0004] Regarding the above-mentioned related technologies, the inventors believe that there are the following technical defects that need to be improved:

For the filtration of nano zinc powder, although the particles of the ultraviolet absorber are generally smaller than the zinc powder particles, a small amount of small particles of zinc powder still remain in the absorber after filtration, and sufficient filtration cannot be achieved.
