High-efficiency continuous garbage aerobic composting device with rapid dehydration function

The invention discloses a high-efficiency continuous garbage aerobic composting device with a rapid dehydration function, and relates to a garbage aerobic composting device. The invention aims to solve the technical problems that the existing small-scale dispersed household garbage treatment in the cold region is not in place, the decomposition efficiency of the garbage aerobic compost at low temperature is low, the dehydration effect is poor, and the compost product quality is poor. The composting device comprises a horizontal fermentation bin, an air blower, an induced draft fan, a gas heat exchange device, a prewashing pool, a biological filter and a controller, aeration holes with different densities are sectionally formed in the surface of a hollow stirring shaft of the horizontal fermentation bin to achieve accurate aeration, spiral paddles and three-blade paddles are alternately arranged on the shaft, the spiral paddles propel materials according to the composting period, dehydration of the materials i
