Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic particles, specifically to a drying machine for plastic particle production. BACKGROUND

[0002] Plastic particles refer to polypropylene, which is a colorless, odorless, non-toxic, translucent solid substance. Polypropylene is a thermoplastic synthetic resin with excellent performance, which is a colorless translucent thermoplastic lightweight general-purpose plastic. As one of the main plastics, polypropylene has good electrical properties and high-frequency insulation that is not affected by humidity, but it becomes brittle at low temperatures, is not wear-resistant, and is prone to aging. It is suitable for making general mechanical parts, corrosion-resistant parts, and insulating parts. In use, the staff needs to dry the plastic particles.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN220489584U discloses a plastic particle drying device. Its technical solution is: a storage cylinder is connected with a conveying assembly at the bottom, the conveying assembly is connected with a air supply assembly on one side, a drive assembly is installed at the upper end of the storage cylinder, a stirring rod is connected with the lower end of the drive assembly, and a collection bowl is installed at the lower end of the inner cavity of the storage cylinder. The beneficial effects of the utility model are: after the air pump extracts air, the heated air forms hot air through the heater, and then the hot air is discharged through the exhaust pipe. Subsequently, the hot air enters the hollow stirring rod through the guide pipe, three-way valve, and connecting pipe. After the hot air enters the stirring rod, it can be dispersed into each branch rod and flow out through the ventilation hole. At the same time, the output end of the drive motor penetrates the lower end of the protection box and is fixedly connected with the stirring rod, which facilitates the rotation of the stirring rod for stirring the plastic particles, makes the plastic particles evenly heated and dried, and accelerates the drying speed.

[0004] However, the existing plastic particle drying device can disperse the hot air into each branch rod after the hot air enters the stirring rod, and then the hot air flows out through the ventilation hole. The ventilation hole does not have a filtering mechanism, and the plastic particles and impurities can easily enter each branch rod through the ventilation hole during the stirring process, which can affect the drying effect.

[0005] Therefore, we propose a drying machine for plastic particle production to solve the above problems. Utility model content
