Description

Vacuum pumping structure of stirring tank for preparing ethylene glycol antimony

Technical Field

The utility model relates to a vacuum exhaust hole structure especially relates to a preparation ethylene glycol antimony uses agitator tank's evacuation structure.

Background

The ethylene glycol antimony is mainly used as a novel catalyst used in the production process of Polyester (PET), can activate related functional groups of reactants in the polycondensation reaction process of the polyester, promotes the reaction, and is used for bottle-grade chips, textile chips, film-grade chips and the like in the production of the polyester. The antimony glycol impurity content is low, so that the antimony glycol is easily dissolved in ethylene glycol, has no toxicity, and has better performance than antimony trioxide and antimony acetate.

Conventional antimony glycol preparation typically requires multiple steps, typically: reaction, filtering, crystallization, centrifugal separation and drying. When negative pressure is required to be pumped to reaction materials by the traditional stirring tank body, a negative pressure port is generally required to be independently arranged on the side wall of the tank body to be connected with a negative pressure device, and when a rotating shaft for stirring extends into the tank body from the top of the tank body, gaps are easy to appear, so that the negative pressure effect is reduced, and the reaction effect is influenced by air mixed in when the negative pressure is pumped.
