Description

Technical Field

[0001] The utility model relates to the technical field of EPS processing, in particular to an EPS particle foaming device. Background Art

[0002] EPS particles are a kind of light polymer. It is made of polystyrene resin with a foaming agent added, and heated to soften, generating gas to form a rigid closed-cell foam plastic, which can be used for reproduction and recycling, which is green and environmentally friendly.

[0003] The existing EPS foaming machines generally use steam for foaming. The steam generated by the steam generator is input into the foaming tank through a pipeline to heat and foam the EPS foam particles. When the existing foaming machines are in use, the EPS particles are stirred to make the contact with the steam more sufficient. During the stirring process, the EPS particles will mostly accumulate at the bottom of the foaming machine, resulting in insufficient contact between the EPS particles at the bottom and the steam, resulting in low foaming quality and efficiency of the material, and poor foaming effect.
