Description

Technical Field

[0001] This utility model belongs to the field of polyester chip production technology, specifically a modified polyester chip drying device that facilitates control of the discharge speed. Background Technology

[0002] Polyester chips are polymer chips made from purified terephthalic acid and ethylene glycol through a polycondensation reaction. They are white granules with good mechanical properties and processability. Modified polyester chips are products with special properties obtained by adding modifiers and changing the molecular structure during the production of polyester chips. Drying is an important step in the production of modified polyester chips. Because the modified chips may contain more hydrophilic groups or have a looser structure, moisture needs to be removed by means of hot air circulation to avoid degradation, bubbles and other problems during processing.

[0003] According to a search, patent document CN216115281U discloses a drying device for polyester chips, including a base, a housing inclinedly disposed on the base, an air supply mechanism fixedly installed on the higher side of the housing, a semi-through groove slidably engaged between the inner and outer sides of the middle part of the housing along the arrangement direction of the housing, and a driving mechanism disposed between the semi-through groove and the side wall of the housing. The housing has an inlet and an outlet. The inlet is located at the top of the housing and close to the air supply mechanism, and the outlet is located on the side wall of the lower side of the housing. The air outlet of the air supply mechanism is connected to the lower part of the housing. The opening of the semi-through groove is arranged upward and the opening end of the semi-through groove is arranged facing the outlet. The sliding trajectory of the semi-through groove is located directly below the outlet. The driving mechanism is used to drive the semi-through groove to slide back and forth rapidly along the arrangement direction of the housing, so that the polyester chips move in the semi-through groove towards the outlet. During the movement of the polyester chips, hot air can dry the polyester chips from all directions.

[0004] The aforementioned comparative document also has the following shortcomings: the drying efficiency of the aforementioned comparative document is low. When hot air is introduced into the shell through the air duct, the air outlet of the air duct is not aligned with the semi-through slot, which causes the hot air to be unable to act accurately on the material, resulting in low heat utilization. At the same time, the discharge port on one side of the shell is large, which causes the heat inside the shell to dissipate quickly, resulting in increased energy consumption. Utility Model Content
