A filtration device for polyurethane production

Abstract

This utility model relates to the field of polyurethane production, specifically a filtration device for polyurethane production. It includes a sealing mechanism for providing a sealed filtration environment, a power component for providing power, and a pump for providing suction. The power component is installed on top of the sealing mechanism, and the pump is installed at the impurity outlet of the sealing mechanism. It also includes a filter screen for filtering polyurethane, a scraping mechanism for removing impurities from the filter screen, and a vibration support mechanism for vibrating and deforming the filter screen to improve the scraping effect of the scraping mechanism. This utility model utilizes the cooperation of the scraping mechanism and the vibration support mechanism. The scraping mechanism and the vibration support mechanism support each other, causing the filter screen to deform. When impurities are filtered through the filter screen, vibration and deformation loosen the impurities stuck in the filter holes, which are then scraped away by the scraping mechanism, improving the scraping and filtration effect and preventing impurities from affecting the filtration efficiency.
