  • Patent number: 12288965
    Abstract: Provided are a new vertical cavity surface emitting laser structure and a manufacturing method thereof. The structure includes a substrate layer, a lower N-type DBR, an active region, an upper N-type DBR and a mixed dielectric DBR sequentially arranged from bottom to top, where a second-class tunnel junction is arranged on one side of the active region close to the upper N-type DBR, where the second-class tunnel junction is embedded in a bottom of the upper N-type DBR and surrounded by the upper N-type DBR, and the substrate layer, the lower N-type DBR, the active region, the upper N-type DBR, the mixed dielectric DBR and the second-class tunnel junction are all coaxial elliptical cylinders; negative electrodes are arranged on the lower N-type DBR, and positive electrodes are arranged on the upper N-type DBRs substrate layer.

  • Patent number: 12115539
    Abstract: A wide-size-fraction flotation system and process includes feeding coal slime to be floated into a stirrer, adding water to the floating coal slime in the stirrer, stirring, then feeding same into a grading cyclone through a first feeding pump for pre-grading; after grading of the coal slime in the grading cyclone, feeding overflow in the grading cyclone into a flotation column through a second feeding pump for flotation, discharging flotation tailings through an underflow port of the flotation column, collecting flotation concentrates through an overflow port of the flotation column and feeding same into a bubble generator through a fourth feeding pump, and the flotation concentrates passing through the bubble generator and being fed from the bottom of a hydraulic flotation machine; and feeding underflow in the grading cyclone into the hydraulic flotation machine through a third feeding pump, for flotation and recovery.

  • Publication number: 20220001395
    Abstract: A flotation process for treating coal slime in which coal slime, a collecting agent and a frothing agent are fed into an ore slurry pretreater, and salt-containing waste water of coal chemical industry discharged from a coal chemical enterprise is fed as dilution water into the ore slurry pretreater and mixed together to complete mineralization; the mineralized ore slurry is subjected to a rough separation operation, the products obtained in the rough separation operation are subjected to a fine separation operation, and the ash content of the fine separation tailings is tested with an ash analyzer; the tailings are returned into the ore slurry pretreater for separation again if the ash content of the fine separation tailings is greater than 20%; otherwise the tailings are discharged as fine separation tailing products if the ash content of the fine separation tailings is smaller than 20%; the fine separation tailing products discharged through a pipeline enter into a pressure filter for dehydration, and filt
