Abstract: A drying apparatus based on peristaltic propelling, including a heat supply module, a drying chamber and a conveying device. The conveying device is arranged in the drying chamber. The drying chamber is provided with a heat source inlet, a heat source outlet, a feeding port and a discharging port. A heat output point of the heat supply module is arranged at the heat source inlet and is configured to provide heat to the drying chamber. The conveying device is configured to provide a platform for laying and propelling a material. The conveying device includes a platform formed by alternate stacking of at least two grid groups. A gap is provided between two adjacent grids. The gap is kept unobstructed and the material is flipped when the material is propelled forward. The gap formed between the adjacent movable grids facilitates improving the fluidity of the air, enhancing the drying efficiency.

Abstract: In a solid-liquid separation apparatus, which comprises multiple movable members and screws that extend and pass through the movable members without contacting the movable members and which dehydrates sludge while conveying same by means of the rotation of the screws, to apply a wringing action on the sludge and increase sludge dehydration efficiency. (Solution) A first movable unit 41 is configured by linking multiple movable members 4A and 4B as a unit with a linking rod 44, a second movable unit 41A is configured by linking multiple other movable members 4C and 4D as a unit with a linking rod 44A, and the movable members 4A and 4B of the first movable unit 41 and the movable members 4C and 4D of the second movable unit 41A are reciprocated with a phase difference.
