A water-based polyurethane filtration device

Abstract

This utility model relates to the technical field of waterborne polyurethane production equipment, and discloses a waterborne polyurethane filtration device, including a filter collection tank and a discharge pipe. The filter collection tank is located below the discharge pipe, and a filter bag is provided at the discharge end of the discharge pipe. Multiple movable slots are respectively opened on the outer wall of the discharge pipe, and an upper cylinder cover is movably installed in each of the multiple movable slots. A support column is fixedly installed inside the filter collection tank. In this utility model, during the squeezing process of the filter bag, the waterborne polyurethane splashed from the filter bag is blocked by the upper cylinder cover, allowing the squeezed waterborne polyurethane to flow into the lower filter collection tank through the gap between the upper cylinder cover and the lower semi-circular cover. The waterborne polyurethane is centrally collected and stored through the filter collection tank. The method of filtering and collecting waterborne polyurethane in this invention can automatically achieve the filtration and collection of waterborne polyurethane without manual operation, thus saving labor.
