Description

Technical Field

[0001] The utility model relates to the technical field of epoxy resin production devices, and particularly relates to a screening device for epoxy resin production. Background Art

[0002] A curing agent, also known as a hardener, curing agent or stabilizer, is a substance or mixture that promotes or controls the curing reaction. The curing of resin is an irreversible change process of thermosetting resin through chemical reactions such as condensation, ring closure, addition or catalysis. The curing is completed by adding a curing (crosslinking) agent.

[0003] During the production of the curing agent, it is necessary to screen it. When screening, the material is fed through a feeding hopper. The discharging port is very easy to be blocked and can only be dredged manually, which is very troublesome. Moreover, too much material discharged at one time will also lead to insufficient screening of the curing agent and reduce the screening effect, having limitations. Summary of the Utility Model
