The utility model discloses a water flow driven rotating device, which relates to the technical field of pre-pump filtration and comprises an outer ring, a flange fixedly connected to the outer surface of the outer ring, an inner ring arranged inside the outer ring, a plurality of blades mounted on the inner wall of the inner ring and fixedly connected with the outer ring, and a detachable support ring slidably assembled inside the inner ring. And a bearing is embedded in the supporting ring. According to the utility model, the filter cartridge can be driven to rotate by using power generated when the water pump sucks water, so that the filter cartridge can be driven to rotate continuously without additionally arranging a driving motor, the rotating speed is controlled only by the flow of water, and the water purifier has the characteristics of energy conservation, safety and high efficiency; the water flow driving rotating device is simple in structure, the sealing type deep groove spherical bearing is adopted to reduce resistance when the filter cylinder rotates, so that the service life of the bearing is guaranteed, the service life of the water flow driving rotating device is prolonged, meanwhile, all parts in the water flow driving rotating device are low in cost and simple in process, production cost can be reduced, and the cost performance is high.

This utility model belongs to the field of underground backfilling of coal mine gangue slurry, specifically relating to an intelligent backfilling system, including the following subsystems: a crushing system, a storage system, a batching system, a slurry mixing system, a pumping system, and a pipeline conveying system. All equipment in each system is connected to a PLC control system. The crushing system includes a steep-angle belt conveyor, a four-toothed roller crusher, and a scraper conveyor above the silo. The end of the steep-angle belt conveyor is connected to the inlet of the four-toothed roller crusher, and the outlet of the four-toothed roller crusher is connected to the starting end of the scraper conveyor above the silo. This utility model has a wide range of applications, suitable for mines with insufficient construction budgets to afford the construction of gangue buffer silos, and also suitable for mines with sufficient construction budgets but poor geological conditions and lack of stratigraphic relationships at the working face, making it impossible to construct large-capacity gangue silos.
