This invention belongs to the field of petroleum coke production technology, and particularly relates to an integrated device for precise proportioning and homogenization of multiple raw materials for petroleum coke. The device includes: a base plate, a rotating frame fixedly installed on the top of the base plate, a mixing drum rotatably installed inside the rotating frame, a rotating rod rotatably installed inside the mixing drum, several stirring rods fixedly installed around the rotating rod, a guide nozzle fixedly installed on one side of the mixing drum, and a drive motor fixedly installed at the bottom of the mixing drum, the output end of the drive motor penetrating the bottom of the mixing drum and coaxially connected to the rotating rod; a power assembly located inside the rotating frame and used to drive the mixing drum to rotate; and a fixed frame fixedly installed on the top of the base plate and located on one side of the mixing drum. This invention allows for flexible adjustment of the total feed amount of corresponding raw materials by adjusting the rotation speed and frequency of the drive motor, achieving precise proportioning of multiple types of petroleum coke, ensuring consistency in the proportion of each batch of mixed materials, and effectively improving the stability of the finished coke's indicators.

The invention relates to the related technical field of preparation of precision casting sand powder, in particular to a production device and method for preparing precision casting mullite sand powder.The production device comprises a flour mill, a valve is arranged on the surface of one side of the flour mill, a feeding groove is formed in the surface of one side of the flour mill, and a discharging port is formed in the surface of one side of the flour mill; a rack is fixedly mounted on the lower surface of the flour mill, a conveying mechanism is arranged on the surface of one side of the flour mill, and a screening mechanism is arranged on the surface of one side of the rack. According to the production device and method for preparing the precision casting mullite sand powder, when raw materials are conveyed into the flour mill, the raw materials firstly enter the material conveying opening, at the moment, the material rolling motor is started, the raw materials are conveyed into the material storage tank through the material conveying pipe, and then the raw materials enter the flour mill through the material conveying opening to be crushed; the arrangement of the material storage tank can ensure the continuous supply of the raw materials, thereby avoiding the idle running of the flour mill caused by insufficient supply of the raw materials, improving the production efficiency and reducing the energy consumption.

This invention relates to a nutrient synergistic regulation system and control method for water-saving wheat cultivation, belonging to the field of wheat cultivation technology. The system includes: mapping soil moisture and nutrient content to a first feature vector; enhancing a wheat growth state image to obtain an enhanced growth state image; extracting a second feature vector from the enhanced growth state image using an image feature extraction network; fusing the first and second feature vectors to obtain a fused feature; inputting the fused feature into a deep learning model for training to obtain a wheat nutrient demand prediction model; and using the wheat nutrient demand prediction model to regulate the nutrients of the target wheat. This invention employs a random forest algorithm, an image feature extraction network, and a deep learning model, which can fully explore and learn the complex relationship between the soil environment and wheat growth state, more accurately reflecting the actual needs of wheat, achieving precise water and fertilizer ratios, and thus improving water and fertilizer utilization efficiency.
