4results about How to "Reduce sorting costs" patented technology

The invention provides an image processing method, electronic equipment and a storage medium, and the method comprises the steps: carrying out the gray processing of an eye fundus image, and obtaining a gray image, the retina in the eye fundus image comprises an optic disc; determining a relationship between a corresponding brightness value and a pixel point based on the grayscale image, and determining a target position of the optic disk; and determining a first classification result of the fundus image according to the target position, wherein the first classification result comprises a left eye image and a right eye image. The method can reduce the classification cost of the eye fundus image and improve the classification precision.

The invention discloses a beneficiation method for pre-enrichment of copper cobalt oxide ores, and particularly relates to the technical field of beneficiation of copper cobalt oxide of low-grade and high-calcium magnesium minerals. The beneficiation step of copper oxide cobalt ore pre-enrichment comprises the steps that copper oxide cobalt ore is crushed to-60 mm; three particle fractions of-60 + 10 mm,-10 + 0.5 mm and-0.5 mm are screened out; carrying out photoelectric separation on a sample with the size fraction of-60 + 10 mm to obtain copper cobalt oxide concentrate I and tailings; carrying out dense medium separation on the sample with the size fraction of-10 + 0.5 mm to obtain copper cobalt oxide concentrate II and tailings; carrying out magnetic separation on a sample with the particle size of-0.5 mm to obtain copper oxide cobalt concentrate III and tailings; and all concentrates are combined, and copper cobalt oxide ore pre-enrichment is completed. According to the method, the copper cobalt oxide ore can be pre-enriched, a large amount of tailings can be discarded, the follow-up selected copper cobalt grade and the selected ore quantity are greatly improved, the cost is reduced, the efficiency is improved, meanwhile, most carbonate ore is discarded, the use amount of acid in the leaching operation process can be remarkably reduced, and the sorting cost is saved.

The application discloses a waste miscellaneous aluminum classification and rapid identification method and relates to the field of waste miscellaneous aluminum classification and rapid identification. S1, grading pretreatment: through a conveying belt, the waste miscellaneous aluminum to be sorted is conveyed into a three-layer vibrating screen machine to be graded and screened, and waste miscellaneous aluminum of different sizes is sorted out; S2, separation of impurities: the graded waste miscellaneous aluminum is conveyed into a drum-type magnetic separator respectively to remove magnetic impurities, then the waste miscellaneous aluminum after magnetic separation is conveyed into an air flow sorting machine to separate light non-metallic impurities, and then a conveying belt conveys the waste miscellaneous aluminum onto a loading platform, full-process automatic processing reduces manual dependence, and the work load of a single production line of sorting workers can be reduced; the classification cost is reduced, compared with manual sorting, the waste product rate of recycled aluminum alloy can be effectively reduced due to accurate classification, and economic benefits are significantly improved.

The utility model discloses circulating type valve plate stamping waste recovery equipment, and particularly relates to the field of valve plate machining, the circulating type valve plate stamping waste recovery equipment comprises an equipment platform and an equipment support located below the equipment platform, a stamping table is installed on the equipment platform, a through waste lower groove is formed in the stamping table, and a funnel-shaped discharging pipe is connected to the bottom of the waste lower groove. An inclined recycling conveying belt is installed on the inner side of the equipment support and located under the discharging pipe, a magnetic suction plate is arranged in the recycling conveying belt, and a metal recycling groove is formed in the edge of the upward-inclined side of the recycling conveying belt. The equipment is compact in structure, can be directly integrated on an existing stamping production line, does not need to greatly reform the production environment, reduces manual intervention through automatic sorting, can reduce sorting cost and improve recovery efficiency for a long time, classified metal can be directly returned to a furnace for smelting, plastic can enter a regeneration production line, mixed pollution is avoided, waste recovery value is improved, and the production cost is reduced. And recycling is realized.
