Description

Technical Field

[0001] The utility model relates to the technical field of anti-blocking feeding, in particular to a feeding device of a PHA modified granular material granulator. Background Art

[0002] A screw feeder is a device used to convey various granular, powdered, or bulk materials. The rotating spiral blades evenly deliver the materials from the hopper, achieving quantitative feeding of the materials. It features high conveying efficiency, safe and reliable operation, simple structure, complete functions, good sealing, low noise, and an attractive appearance.

[0003] Due to the performance defects of a single PHA, PHA modified materials are currently usually blended and modified with different types of PHA to improve their overall performance. However, for PHA powder materials, the melting temperature of some PHA powders is low, and as the temperature increases, the viscosity of this type of powder will also increase. During the feeding process, as the spiral blades continue to stir, the temperature of the powder will increase, resulting in an increase in the viscosity of the PHA powder, and then forming a bridging phenomenon with full top and empty bottom. This bridging phenomenon leads to instability in the production process and uneven mixing of the pellets, which greatly damages the production. Therefore, it is necessary to optimize the feeding system to solve the problem of PHA powder clogging during the production process. Therefore, we propose an anti-clogging feeding device for a PHA modified pellet granulator.

[0004] The above-mentioned prior art solution has the following defects: a rotary stirring device is added to the existing screw feeder hopper, so that the powder can be stirred and dispersed, thereby avoiding the bridging problem of PHA powder. Utility Model Content
