The flipping plate of the filter press, also known as the liquid receiving plate or the liquid collecting plate, is a liquid collection device installed below the filter plate. When the filter press is feeding, the leaked liquid below the filter plate flows into the flipping plate (automatic water collection plate) and then flows to both sides of the filter press. It is collected into the centralized pool through the liquid collection tank. The main advantage of this device is to prevent the liquid from flowing into the filtered solid material. It can reduce costs and improve efficiency. It is more advantageous to concentrate the washing solution when washing the filter cloth, reducing the labor intensity of workers.
