Description

Technical Field

[0002] PVC heat stabilizers are a type of additive that can prevent or reduce the degradation or cross-linking of polyvinyl chloride (PVC) caused by heat during processing and use, thereby extending the service life of the composite material. They have high stability, good transparency, excellent heat resistance, and are mostly in powder or granular form.

[0003] After being stored for a long time, PVC heat stabilizer needs to be dried to facilitate its subsequent use as an additive. However, granular PVC heat stabilizer may clump after being idle for a long time. In order to pre-disperse the PVC heat stabilizer to facilitate its drying in the dryer, a feeding mechanism for a PVC heat stabilizer dryer is designed. This mechanism preferentially feeds the PVC heat stabilizer into the inner cavity of the feeding box. At this time, under the action of the scattering structure, the lumpy PVC heat stabilizer will be broken up and separated, so that the PVC heat stabilizer can be pre-dispersed to facilitate its drying in the dryer.
