The invention discloses a beneficiation method for improving comprehensive recovery indexes of complex low-grade molybdenum polymetallic ores, and particularly relates to comprehensive recovery of valuable elements such as molybdenum, copper and sulfur in low-grade molybdenum ores. According to the method, the effective flotation separation of molybdenite, chalcopyrite and pyrite can be realized,and the comprehensive recovery indexes of the low-grade molybdenum ores are improved. The method comprises the following steps of primary ore grinding, molybdenum (molybdenite) flotation, secondary ore grinding (rough molybdenum copper concentrate regrinding), copper (chalcopyrite) flotation, and sulfur (pyrite) flotation. The method is stable and effective in reagent regime and beneficiation process flow and high in adaptability. By using the beneficiation method, high-quality molybdenite, chalcopyrite and pyrite are obtained from the complex, difficult-to-select and low-grade molybdenum polymetallic ore with associated copper/ sulfur, and the comprehensive recovery indexes of sulfide minerals are excellent. The adopted reagent is non-toxic and harmless, has little influence on the environment, and is an excellent beneficiation method.

The invention relates to the technical field of underwater robots, in particular to an emergency suspension device. An emergency suspension device for a seabed sonar robot comprises a connecting base, a slow lifting mechanism and a quick lifting mechanism, whereinthe top of the connecting base is provided with a supporting cylinder, a connecting ring and a top cover, a corrugated pipe is connected between the connecting ring and the top cover, and an air bag sleeve is arranged between the connecting ring and the top cover; the slow lifting mechanism comprises a first self-locking motor and a mounting seat, and a first lead screw is connected with a threaded cylinder at the center of the mounting seat; and the quick lifting mechanism comprises a second self-locking motor and a second lead screw, and the second lead screw is connected with the threaded cylinder at the top of the supporting cylinder. The lead screw is arranged between the top cover and the connecting ring for transmission, the corrugated pipe between the top cover and the connecting ring can be freely adjusted according to needs to form the size, and the robot can slowly move upwards conveniently; besides, a gas generator is arranged in the high-pressure area, an electromagnetic valve is arranged on the partition plate, the expansion degree of the air bag sleeve can be freely adjusted according to needs, and therefore the floating speed of the robot is controlled.

The invention relates to the technical field of medicines, in particular to a tofacitinib gastric retention floating type sustained release tablet and a preparation method thereof. The tofacitinib gastric retention floating type sustained release preparation provided by the invention takes carbomer as gel and is matched with proper expanding agent, floating agent, controlled release material and other auxiliary materials. All the components are properly selected and reasonably matched, so that the prepared controlled release tablet can quickly float in a stomach environment, the effective components are released and absorbed in a relatively low-pH environment, and the bioavailability is improved. Experiments show that the preparation rapidly floats after being put into a dissolution cup and continuously floats in a dissolution medium for at least 10 hours. In a medium with the pH value of 6.8, the medicine is stably and completely released within 10 hours; in simulated gastric juice, the release rate of the medicine in 6h is greater than 85%.

The invention discloses an intelligent drainage type cleaning pool. The intelligent drainage type cleaning pool comprises a frame body, wherein a cleaning pool body is arranged in the frame body; a plurality of spray heads are arranged above the cleaning pool body; a plurality of cleaning brushes are arranged in the cleaning pool body; a space for removing peach hair is formed between every two adjacent cleaning brushes, and the cleaning brushes are further connected with a driving device used for driving the cleaning brushes to shake; a turbidity sensor is arranged on the side wall of the upper portion of the cleaning pool body; an upper water outlet and an upper water inlet are further formed in the upper portion of the cleaning pool body, and are provided with a first one-way valve anda second one-way valve respectively; the turbidity sensor is connected with a controller, and the controller controls opening and closing of the first one-way valve and the second one-way valve; a water pipe is connected between the upper water outlet and the upper water inlet; and a purifying device is arranged in the water pipe. The design of the shaking type cleaning brushes is adopted, so thatthe cleaning brushes continuously shake back and forth in the direction perpendicular to the cleaning brushes, and peach hair on the surface of each peach is removed.

The invention relates to a silicon-barium-strontium-iron alloy deoxidizer. The silicon-barium-strontium-iron alloy deoxidizer comprises the following components in percentage by weight: 23 to 31 percent of silicon, 8 to 14 percent of barium, 11 to 18 percent of strontium and the balance of iron and is characterized by comprising 2 to 9 weight percent of cobalt oxide or titanium oxide, wherein the granularity of a silicon-barium-strontium-iron alloy and the cobalt oxide or the titanium oxide is between molecular level and 100nm. In the deoxidizer provided by the invention, the silicon-barium-strontium-iron alloy is mixed with the cobalt oxide or the titanium oxide, and the mixture is used as a molten steel deoxidizer. Compared with a single alloy deoxidizer, the silicon-barium-strontium-iron alloy deoxidizer has an obvious deoxidizing effect; particularly, an Al2O3 inclusion in a type of steel with low requirements on the content of aluminum and sulfur can be changed and reduced. The deoxidizer can make all alloy elements exert a coordinating function in the deoxidizing process, so that the inclusion can be formed quickly and float on the surface of molten metal; and the deoxidizer has extremely ideal effects of deoxidization, desulfurization and dephosphorization.
