The application provides a provincial meteorological and administrative collaborative wind speed prediction method based on dynamic federal learning, relates to the cross technical field of artificial intelligence and energy meteorology, S1, basic data of N meteorological monitoring stations in a province is acquired, is divided into M initial subgraphs according to the administrative boundary of a prefecture-level city and is allocated an edge server, each collaborative subgraph pair is determined according to the Pearson correlation coefficient of the wind speed sequence of the station, the time sequence data deviation of the synchronized subgraph is synchronized through a dynamic time warping algorithm after every 3 rounds of federal iteration, and the subgraph data after synchronization is output. Through an endogenous decision and optimization framework, three links of dynamic coordination of cross-domain collaboration, local learning and gradient transmission are coordinated, and finally a global optimal provincial meteorological and administrative collaborative wind speed prediction method based on dynamic federal learning is achieved among multiple targets such as prediction accuracy, convergence speed and communication cost.

This utility model relates to the field of rotary kiln waste heat recovery technology, and discloses a rotary kiln waste heat recovery device, including: a kiln body and a rotary cylinder. The rotary cylinder is rotatably mounted inside the kiln body. A high-temperature waste gas outlet pipe is provided at the top of one end of the kiln body. A dust removal filter cylinder is provided at one end of the high-temperature waste gas outlet pipe. Waste heat waste gas guide pipes are provided on both sides of one end of the dust removal filter cylinder. One end of the waste heat waste gas guide pipe is connected to both sides of the kiln body. This utility model sets the introduction point of high-temperature flue gas on the side of the kiln, utilizing the characteristic that the density of high-temperature flue gas is less than that of air, promoting the smooth penetration of heat flow from bottom to top under the action of density difference, forming a stable and effective heat convection. This design ensures that the rotary cylinder of the kiln is uniformly heated within a 360° range, without any heating blind spots, guaranteeing the evenness of heating of the cylinder.

The utility model relates to one -way valve technical field especially relates to a liquid chromatograph one -way valve, solved the problem among the prior art. A liquid chromatograph one -way valve, including the tubulature, both ends of tubulature all have the threaded connection pipe of intercommunication, the inside one side of tubulature is connected with the water inlet pipe, the top elastic connection of water inlet pipe has the valve cover, the inside upper portion one side of water inlet pipe is fixedly connected with the connecting plate. The utility model makes the valve cover and the connecting plate between form by the initiative reset mechanism of extension spring drive, has improved the response speed and action reliability of valve cover closing significantly, even under the working condition that pump cavity pressure drops rapidly or exists transient negative pressure, can also ensure that the valve cover resets seal quickly, has prevented the reverse leakage of mobile phase, improved the stability of infusion flow and the repeatability of analysis data, avoided the baseline fluctuation and chromatographic peak distortion caused by backflow or bubble introduction.

This invention relates to the field of phenolic resin technology, specifically to a preparation process for polymerized rosin-modified phenolic resin. First, polymeric rosin with high dimer content is purified by devolatilization, adsorption decolorization, and antisolvent precipitation to obtain directionally polymerized rosin A. Then, an epoxidation reaction is performed to obtain epoxidized product B. Subsequently, cashew phenol, 3-pentadecanylphenol, and oleic acid are grafted in stages to obtain directionally modified polymeric rosin C. Simultaneously, a phenolic prepolymer is prepared. Finally, the prepolymer, modified rosin C, and natural rosin are polycondensed together, and an antioxidant is added to obtain the finished product. This process, through directional control of raw materials and staged reaction control, enables the resin to possess high softening point, light color stability, high n-heptane tolerance, and excellent processing safety, significantly improving batch consistency and making it suitable for high-performance ink binders.
