Description

TECHNICAL FIELD

[0001] The utility model relates to polyester product production device technical field, specifically, relate to a polyester elastomer dehumidification dryer. BACKGROUND

[0002] Polyester elastomer is also called TPEE, which is a linear block copolymer containing PBT (polybutylene terephthalate) polyester hard segment and aliphatic polyester or polyether soft segment. TPEE has excellent elasticity of rubber and easy processability of thermoplastic plastic, adjustable softness and hardness, and design freedom. It is a new variety of thermoplastic elastomer that attracts much attention. The production method of polyester elastomer is similar to that of polyurethane elastomer. After underwater granulation is completed, the elastomer after granulation needs to be dried.

[0003] After searching, it is found that the application No. CN202320767369.X, named thermoplastic elastomer material dryer, proposes that the drying gas of elastomer contains volatile gas and has certain toxicity, which needs to be filtered. The traditional dried gas needs to be filtered by a separate filtering device before being discharged, which is troublesome. The air is heated by the heating sheet group and then enters the heat exhaust plate, and then the uniform hot air is discharged into the drying chamber. The air flows in the drying chamber, and the shelf is slowly rotated to achieve uniform heating and drying effect. The dried gas is first filtered by the activated carbon filter block, and then the toxic gas is reacted by the solution to make the discharged gas meet the emission standard. However, the activated carbon block needs to be replaced after saturation, which is troublesome and affects the work efficiency. At the same time, the hot gas is not dehydrated, which will quickly saturate the activated carbon and lose its effect, increasing the replacement frequency and the inconvenience of use. Further improvement can be made.
