PURPOSE: To uniformly place a muddy solid-liquid mixture flowing down from a flowing-down plate on filter cloth and to smoothly progress solid-liquid separating treatment by forming the flowing-down plate into descending slope toward the circumferential direction of the filter cloth and also downward curving the flowing-down plate and forming a solid-liquid guiding face projected upward in the width direction of the filter cloth.
CONSTITUTION: In a flowing-down plate 42, a sludge flowing part 51 continues in such a shape that it is connected to the tip of a narrow sludge introduction part 50. The flowing face of the sludge flowing part 51 is formed into a sectoral shape widened toward the traveling direction of filter cloth 2. The whole is formed into descending slope along the traveling direction of the filter cloth 2 and also the center is high along the width direction of the filter cloth 2 and the sludge flowing part is formed into descending slope toward both sides. Therefore, sludge supplied to the sludge introduction part 50 flows down on the flowing face of the sludge flowing part 51 along two directions of the traveling direction and th width direction of the filter cloth 2 and is fully broadened and then flows down on the filter cloth 2. As a result, sludge is uniformly placed on the filter cloth 2.
