[0030] Working principle: When the building-type turning and drying equipment is in use, the sludge is added into the receiving hopper 4 of the turning and drying equipment on the top layer, and the sludge then falls from the bottom of the receiving hopper 4 into the double-axis screw feeder 8, and the double-axis screw feeder 8 transports the sludge to the ground on the top layer, and at the same time, the turning and drying main frame 3 is driven by the walking mechanism 2 to move along the track 1, and the turning and drying main frame 3 drives the receiving hopper 4 and the sludge spreading mechanism 7 to move, so that the sludge falls fully to the ground, and when the sludge spreading mechanism 7 moves, the sludge on the ground is displaced laterally along the spreading plate 702 in turn, so that the sludge is spread flat on the ground, and after many round trips, the sludge is gradually pushed laterally from the left end to the right end, and the transmission shaft 502 and the turning and throwing claw 503 are driven to rotate by the second reduction motor 501, and the sludge is turned and thrown by the turning and throwing claw 503, so as to increase the sludge contacting air area, accelerate the drying, and the sludge. After being pushed to the rightmost end, it falls into the second layer, and then the material is flipped from the second layer from right to left, and finally falls into the bottom layer at the leftmost end. The bottom layer is flipped and moved from left to right. The sludge is realized after multiple movements to form a spatial overhead mobile drying. The air inlet on one side and the air outlet on the other side of the two ends of the factory building conveys air to the induced draft duct 601 through the induced draft fan 6, and the air flow is balanced through the inlet and outlet valves. It runs for a long time inside the workshop to form a stable and balanced airflow, which increases the air circulation and accelerates the drying effect. Through the superposition of equipment and facility space, a larger space flipping and drying space is formed, which greatly reduces the floor area. The flipping and spreading mechanism of the flipping equipment is operated to increase the contact area between the sludge and the air, and the induced draft fan 6 is used to increase the air flow inside the factory building. At the same time, it is equipped with fluorescent light transmission and floor heating to accelerate the evaporation of water in the sludge and shorten the sludge drying process.
