Description

Technical Field

[0001] The utility model relates to the technical field of PBT copolyester esterification reaction, in particular to a reaction device capable of continuous feeding. Background Art

[0002] PBT copolyester generally refers to copolyester. Copolyester (Z-resin) is a new series of transparent engineering plastics, a perfect combination of high transparency, high impact resistance and high chemical resistance. Conventional polyester is widely used. With the increase in social demand for polyester products, its production scale has also increased. Copolyester needs to undergo esterification reaction in a reactor during production.

[0003] After production, PBT copolyester undergoes a series of processing and is often processed into granular form for easy storage, transportation and subsequent processing and use.

[0004] In the existing PBT copolyester reaction device, when reacting PBT copolyester, granular PBT copolyester is usually fed manually. When placed manually, not only the amount placed cannot be controlled, but also the PBT copolyester is very easy to be blocked during the feeding process. In addition, during the placement process, the operator frequently maintains the same action and is very easy to get tired. To solve this problem, we proposed a reaction device that can continuously feed. Utility Model Content
