[0001] The utility model relates to the technical field of static electricity removal oven, specifically relates to a particle static electricity removal oven for EPP material processing. BACKGROUND

[0002] In the processing of EPP particles, due to friction, contact and other reasons, static electricity is easily accumulated on the surface of the particles. These static electricity not only affects the processing performance of the particles, but also may cause problems in the subsequent production process, such as adhesion between particles, dust explosion and other safety hazards.

[0003] In the process of removing static electricity from EPP particles, the method of spraying diluted surfactant and dehumidifying is usually used to uniformly coat a layer of surfactant on the outside of EPP particles. This layer of surfactant can adsorb a layer of water film on the surface of EPP particles, thereby minimizing the static deposition on the surface of EPP particles. After spraying the surfactant, the excess water needs to be removed. The traditional static electricity removal oven may have the problems of slow drying rate and uneven drying, which may require long-time use of the oven, resulting in increased energy consumption and working time.
