Feeding anti-agglomeration device in production of saturated polyester resin

Abstract

The invention provides a feeding anti-agglomeration device in production of saturated polyester resin, belonging to the technical field of machinery. The feeding anti-agglomeration device in production of the saturated polyester resin comprises a reaction kettle, wherein a pipe body is fixedly arranged at the upper part of the reaction kettle; an upper cover and a lower cover are respectively andfixedly arranged at the upper end and the lower end of the pipe body; a feeding pipe is connected with and arranged at the upper part of the pipe body; a discharging pipe is connected with and arranged at the lower part of the pipe body; a sealing structure is respectively arranged on the discharging pipe and the feeding pipe; the pipe body is used for storing liquid or solid raw materials; a rotating pipe is rotatably arranged in the pipe body; a driving mechanism I used for driving the rotating pipe to rotate is arranged on the pipe body; a stirring mechanism used for stirring raw materialsis arranged on the rotating pipe and comprises a plurality of stirring assemblies; a stirring chamber can be formed between every two adjacent stirring assemblies; and each stirring assembly comprisesa plurality of stirring blades. The feeding anti-agglomeration device provided by the invention has the advantages of high stirring efficiency and no agglomeration of the raw materials.

Description

technical field [0001] The invention belongs to the technical field of machinery, in particular to a feeding anti-agglomeration device in the production of saturated polyester resin. Background technique [0002] In the production of saturated polyester resin, due to the direct feeding of solid powder raw materials and liquid raw materials in proportion, the raw materials of each component are dispersed unevenly, and agglomeration of different sizes occurs, which makes the esterification reaction and polycondensation reaction incomplete, which affects the performance and quality of the product. and color, especially in recent years, in order to reduce production costs, polyester production has adopted large-capacity reactors for production. Due to the unavoidable large stirring dead angle in the reactor, the phenomenon of incomplete reaction often occurs due to the agglomeration of raw materials, which seriously affects the stability of product quality and the change of color...
