The application discloses a cooling and condensing device for electromagnetic wire processing and relates to the technical field of electromagnetic wire processing equipment.The device comprises a rack and a self-adapting adjusting component, and an alternating-current power supply is fixedly installed at the bottom of the rack.The cooling and condensing device for electromagnetic wire processing realizes power linkage based on the electromagnetic vortex induction principle.The electromagnetic iron under alternating-current power supply generates a vortex effect in cooperation with the metal wire body passing through, and different wire bodies generate vortexes with different intensities according to the law of electromagnetic induction, so that the electromagnetic attraction of the electromagnetic iron to the armature is changed, the armature can axially slide along the limited track of the rear guide sleeve, the displacement change close to or away from the electromagnetic iron is realized, the physical change amount of the wire diameter is passively converted into a mechanical displacement amount, and the stable and reliable movement basis can be provided for the synchronous linkage adjustment of the subsequent pre-cleaning component and the gap adjusting component without the need of electric control sensors and additional driving elements.The device has the advantages of simple structure, strong anti-interference capability and adaptation to the wet processing working condition of electromagnetic wire.

This invention belongs to the field of waste plastic pyrolysis resource utilization, specifically a machine learning-based process optimization method for preparing light aromatics from waste plastic pyrolysis. This method constructs a dataset based on raw material characteristics, pyrolysis conditions, and product data from published literature, performs preprocessing, trains and optimizes various machine learning regression models, and selects the optimal model for predicting light aromatics yield based on evaluation indicators. Then, interpretability analysis is used to identify key factors affecting the yield, and raw material structural characteristics such as saturated C-H bonds, methyl branches, and carbonyl groups are used as inputs to enhance the characterization of raw material differences. Under industrial constraints, with the light aromatics yield as the optimization objective, a particle swarm optimization algorithm is used to globally optimize the reaction condition parameters to obtain the optimal combination of operating parameters. This invention can achieve light aromatics yield prediction and operating parameter recommendation under fluctuating raw material composition, improving prediction stability and generalization ability, reducing experimental iterations, and lowering optimization costs.
