Technical Field

[0002] Biodegradable plastics refer to a type of plastics that are degraded by the action of microorganisms existing in nature, such as bacteria, molds (fungi), and algae. Ideal biodegradable plastics are high-molecular materials with excellent service performance, which can be completely decomposed by environmental microorganisms after being discarded, and finally become an inorganic part of the carbon cycle in nature.

The feeding main body and the drying box are respectively fixedly installed on the support bottom plate and are adjacent to each other. The dust removal and screening feeding mechanism is arranged in the feeding main body, and the multi-dimensional vibration drying mechanism is arranged in the drying box. When in use, biodegradable plastic particles are placed into the barrel. When the screening inclined plate ascends and descends, it drives the limit baffle to ascend and descend. The limit baffle corresponding to the feeding port opens and closes the feeding port when sliding up and down. The biodegradable plastic particles falling on the screening inclined plate roll along the inclined plane and enter the collection cloth bag through the feeding port to collect the biodegradable plastic particles. When the biodegradable plastic particles fall in the feeding main body, the hot air blower is started. The hot air blower injects hot air flow into the pressure cavity through the air inlet pipe and finally discharges it through the exhaust pipe, blowing towards the falling biodegradable plastic particles, blowing the dust or small-sized waste materials and scraps towards the electrostatic adsorption plate, and being adsorbed and removed by the electrostatic adsorption plate.
