Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a titanium series polyester catalyst production reaction kettle. Background Art

[0002] Titanium-based catalysts are favored by many polyester manufacturers due to their high activity and lack of heavy metals. Titanium-based catalysts are also a research hotspot for polyester catalysts in recent years. The production method commonly used in the production of titanium-based polyester catalysts is to add anhydrous ethanol, nano-silica, titanate and ethylene glycol into a reactor, heat under nitrogen protection and vigorous stirring, and after heat preservation and reaction, a white product is obtained, which is filtered, washed, and vacuum dried to obtain a polyester catalyst with nano-silica as a carrier and titanium ethylene glycol as a catalytic active center.

[0003] However, currently, after the raw materials enter the reactor, the catalyst is stirred by the stirring blades inside the reactor. However, due to the same specifications and swinging directions of the stirring blades, when the catalyst raw materials are stirred, a vortex will be generated and synchronized with the rotation speed of the stirring blades, thereby affecting the stirring effect, and the catalyst raw materials are prone to precipitation. Therefore, a titanium polyester catalyst production reactor is provided to solve the above problems. Utility Model Content
