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.

The invention relates to a small photo-thermal utilization system and method suitable for an oil field station. The system comprises a solar heat collector, a heat storage device, a variable frequency pump, a heat exchanger, a PLC control cabinet, a low-voltage control cabinet and a variable-frequency governor. The solar heat collector is connected with the heat exchanger and the heat storage device, the variable frequency pump is connected between the heat exchanger and the heat storage device, the heat exchanger is connected with a well site produced liquid pipeline and an oil field station crude oil treatment pipeline, and the variable frequency governor is connected with the variable frequency pump. The PLC control cabinet is connected with the solar heat collector, the heat storage device, the heat exchanger and the low-pressure control cabinet. When the first temperature signal of the solar heat collector is larger than or equal to the first working temperature signal, the PLC control cabinet controls the solar heat collector to directly exchange heat for the heat exchanger, and redundant heat is stored in the heat storage device. Under cloudy and rainy weather and night conditions, the heat storage device exchanges heat with wellhead produced liquid through a high-temperature heat supply medium, and application of solar photo-thermal utilization in an oil field station yard is achieved.

The invention discloses a preparation method of manganese-loaded bean dreg baking charcoal and application of the manganese-loaded bean dreg baking charcoal in purification of malachite green in aquarium fish culture water. The preparation method comprises the following steps: by taking kitchen residue bean dregs as a raw material, washing, drying and crushing the kitchen residue bean dregs, soaking the bean dregs in a phosphoric acid solution for pretreatment, soaking the bean dregs in a potassium permanganate buffer solution for manganese loading, and finally performing a low-temperature baking technology, thereby obtaining the manganese-loaded bean dreg baking charcoal. According to the method, value-added utilization of kitchen residue bean dregs and low-temperature waste heat resources is achieved, the prepared manganese-loaded bean dreg baking charcoal has efficient adsorption capacity on malachite green in water, the maximum adsorption capacity of the manganese-loaded bean dreg baking charcoal reaches 373.4 mg / g, and the manganese-loaded bean dreg baking charcoal can be used as an efficient adsorbent for purifying malachite green in aquarium fish culture water.
