Description

Technical Field

[0001] This utility model relates to the field of photocurable material processing technology, and in particular to a filtration device for photocurable high-viscosity monomers. Background Technology

[0002] The filtration device for high-viscosity monomers in photocurable materials production is a piece of equipment used to perform filtration operations on high-viscosity monomers. It consists of a feeding device, a filtration assembly, a heating and stirring unit, and a discharging device. It is installed in the photocurable materials production line to efficiently remove impurities from high-viscosity monomers and ensure the purity and quality of photocurable products.

[0003] If impurities in high-viscosity monomers are not effectively removed during the manufacturing process of photocurable materials, they will interfere with the polymerization process during the photocuring reaction, resulting in performance defects in the product, such as incomplete curing, insufficient hardness, and reduced transparency. This seriously affects product quality, increases the defect rate, and reduces the company's economic benefits and market competitiveness.

[0004] When traditional filtration devices process high-viscosity photocurable monomers, the poor flowability and high viscosity of the material make it difficult to pass through the filter paper layer, resulting in low effective filtration efficiency and affecting product purity. Existing technologies generally use plate and frame filter presses combined with industrial filter paper, and pre-treat the high-viscosity monomers by heating to reduce viscosity before filtration. However, in actual use, the removal effect of impurities is still not good after heating to reduce viscosity. Moreover, the overall impurity removal effect of plate and frame filter presses with industrial filter paper through pressure filtration is generally average, which cannot meet the strict requirements of high-quality photocurable products for monomer purity.

[0044] Working principle: The high-viscosity monomer raw material to be processed is introduced into the device through the feeding mechanism 5. The bottom of the feeding funnel 501 is connected to the top left side of the box cover 407. The raw material enters the heating box 401 through the feeding port 502.

The sliding rods 3061 are fixed on the left and right sides of the threaded pressure plate 305 and move within the sliding rails 3062 to ensure that the pressure plate moves smoothly up and down. The filtered liquid is discharged through the draining mechanism 7. The left end of the guide pipe 701 is connected to the right side of the collecting cylinder 601 to guide the filtered liquid out. The check valve 702 on its outer wall prevents the liquid from flowing back. The liquid finally flows into the collecting tank 801 of the collecting mechanism 8. The bottom of the collecting tank 801 is connected to the top right side of the support base 1. The internal collecting filter screen 802 further separates particulate impurities from the liquid, completing the entire filtration process.
