The application discloses a large-flow mud circulating system and a deslagging method for super-large-section shaft construction, and belongs to the technical field of tunnels and underground engineering. The deslagging method comprises the following steps: collecting mud pressure, concentration, flow rate and excavation face muck profile data of each branch pipeline; fusing the collected multi-dimensional observation data to generate an excavation face muck deposition thermal diagram, identifying a high-risk muck accumulation area and calculating a target suction flow instruction value for optimizing flow distribution; adjusting the valves and pump groups of each branch pipeline based on the target suction flow instruction value, driving the jet nozzle to perform targeted flushing on the high-risk area and forming a local reinforced circulating flow; and continuously pumping the mud containing muck to the ground slurry treatment station through the annular main pipe, and the ground station performs solid-liquid separation on the muck-containing mud. The application dynamically adjusts the mud circulating operation in the super-large-section shaft construction in real time, accurately identifies and processes the muck accumulation area, and ensures efficient and sustainable cleaning operation.

This invention provides an automatic slag removal mechanism for drying equipment, its installation method, and its application, belonging to the technical field of slag removal structures for drying equipment. The automatic slag removal mechanism includes a driven shaft seat, a driven roller, a slag removal pipe, a spiral shaft, and a transmission structure. Two driven shaft seats are provided and arranged opposite to each other. The driven roller is rotatably installed between the two driven shaft seats and is used for supporting and guiding the conveyor belt of the drying equipment during reversal. The slag removal pipe is fixed between the two driven shaft seats, parallel to the driven roller, and positioned on the side of the driven roller away from the conveyor belt. A notch is provided on the side of the slag removal pipe facing the driven roller. In the above solution, the automatic slag removal mechanism for drying equipment, its installation method, and its application realize the automatic scraping, collection, and conveying discharge of residue from the driven roller, without manual intervention or machine shutdown for slag removal, effectively improving slag removal efficiency, ensuring continuous operation of the equipment, and increasing production efficiency.

This utility model relates to a combined high-temperature material feeding hopper, including a feeding hopper and a cylindrical cooling feeding pipe. The feeding hopper has an inclined conical feeding structure that is larger at the top and smaller at the bottom. The slope of the left feeding face is greater than that of the right feeding face. The left feeding face has a wear-resistant inner layer and an outer layer. A slag-removing hole is provided on the right feeding face. The cylindrical cooling feeding pipe is connected to the bottom of the feeding hopper and is inclined to the right. A cooling jacket is formed by the inner wall and outer wall of the feeding pipe. A slag-removing hole is provided on the right side of the cylindrical cooling feeding pipe. Both the hopper slag-removing hole and the feeding pipe slag-removing hole have detachable sealing slag-removing gates. The bottom of the cylindrical cooling feeding pipe has a discharge port connected to the inlet of a slag cooler. Through the asymmetrical design of the inclined conical hopper, the wear-resistant left feeding face, and the slag-removing right side, combined with the right-inclined water-cooled cylindrical feeding pipe, a combination of cooling and slag removal is achieved, which extends the wear life, improves the slag removal efficiency, and reduces the outlet material temperature.
