Description

TECHNICAL FIELD

[0001] The utility model relates to final polycondensation disc reactor, especially the dynamic disc structure of final polycondensation disc reactor. BACKGROUND

[0002] The final polycondensation reactor is a key equipment in polyester production, which is mainly used for completing the further growth of polyester chain and the improvement of polymerization degree. In the reactor, through high temperature and high vacuum conditions, the oligomer is repeatedly dehydrated and polycondensed and de-EG (ethylene glycol) polycondensed to form polyester macromolecular chain. The stirring device in the reactor ensures the uniform mixing of materials, and promotes the removal of small molecular products at the same time, so as to achieve the required polymerization degree and viscosity. The disc reactor is a typical structure of the final polycondensation reactor, and the stirring mechanism in the disc reactor has an important influence on the film drawing effect of the polyester melt. The dynamic disc is one of the main stirring components in the stirring mechanism, therefore, it is necessary to design a dynamic disc structure with good film drawing effect. SUMMARY

[0003] The embodiment of the application provides a dynamic disc structure for improving the film drawing effect. The embodiment of the application also provides a final polycondensation disc reactor adopting the dynamic disc structure.

[0004] The first aspect of the application provides a dynamic disc structure, comprising:

[0005] A shaft sleeve;

[0006] A spoke connected to the shaft sleeve;

[0007] A plurality of ring plates arranged axially along the shaft sleeve, wherein part of the ring plates are connected to the spoke;

[0008] A connecting plate connecting the ring plates;

[0009] A distance plate arranged between adjacent ring plates.

[0010] The above embodiment has the beneficial effect that the distance between the ring plates is ensured by the distance plate, the overall structure is fixed and formed by the connecting plate to improve the structural strength, and the contact area with the material is increased by the distance plate and the connecting plate, thereby increasing the evaporation area to improve the film drawing effect.

[0011] On the basis of the above embodiment, the embodiment of the application can also be improved as follows:

[0012] In one of the embodiments of the present application, the shaft sleeve is provided with an annular boss, and the spoke is connected to the annular boss. The beneficial effect of this step is that, since the spoke is usually connected to the shaft sleeve by welding, the thickness of the corresponding structure of the shaft sleeve is increased by the boss, thereby improving the structural strength and avoiding welding deformation, and meanwhile, since the structure of other parts of the shaft sleeve is not increased, the mass of the shaft sleeve is smaller while the connection strength is ensured.

[0013] In one of the embodiments of the present application, the connecting plate is arranged circumferentially along the ring plate, and the connecting plate penetrates all the intermediate ring plates except the outermost ring plate. The beneficial effect of this step is that the circumferential arrangement of the connecting plate can reduce the resistance during stirring, thereby reducing the stress of the stirring shaft, and the connecting structure formed by penetrating the intermediate ring plate has high strength.

[0014] In one of the embodiments of the present application, the distance plate is arranged circumferentially along the ring plate. The beneficial effect of this step is that the circumferential arrangement of the distance plate can reduce the resistance during stirring, thereby reducing the stress of the stirring shaft.

[0015] In one of the embodiments of the present application, the connecting plate and the distance plate are arranged in a staggered manner in the circumferential direction and the radial direction of the ring plate. The beneficial effect of this step is that the multiple positions of the connecting plate and the distance plate on the surface of the ring plate can improve the strength of the overall structure, and the staggered structure also forces part of the moving material to contact the connecting plate and the distance plate.

[0016] In one of the embodiments of the present application, the connecting plate and the distance plate are provided with holes on the surface. The beneficial effect of this step is that the holes can reduce the mass of the connecting plate and the distance plate, thereby reducing the mass of the impeller, and also allowing part of the material to flow through the holes, ensuring that the material has a certain flow rate.

[0017] The second aspect of the present application provides a final polycondensation disc reactor comprising the impeller structure. BRIEF DESCRIPTION OF DRAWINGS
