There are following some shortcomings in existing physics method: it is very high that (1) requires to reclaim material quality, " particular about food " phenomenon of originating highly stable; (2) even reached the quality requirements of raw material, also because reclaimed materials has always passed through processing, the quality that causes in process descends and cannot repair; (3) quality uniformity of raw material does not reach the high-quality of industrialized unit, successional requirement.

Summary of the invention

The purpose of this utility model is the physics method above shortcomings that reclaim raw material regeneration at existing, provide and to change molecular chain structure, polyolefin and derivative class organic impurities thereof such as PVC, the PP in the removal recovery raw material, PE, thereby a kind of melt polycondensation high polymer old material regeneration device that the chemical method of the purity of raising regenerative raw materials and quality uses.

The purpose of this utility model is achieved through the following technical solutions, a kind of melt polycondensation high polymer old material regeneration device, it is characterized in that, described regeneration uses device by cylindrical tube, the cylindrical shell two ends are through the bolted end cap of lip weldering sealing flange, the oblique anti-blocking liquid level gauge mouth down that end cap is provided with near the bottom, the combination vacuum seal mechanism that tape spool that respective end covers holds is passed at the shaft two ends that are provided with in the cylindrical shell, the stirring disc of fixed interval successively from front to back on the shaft, an end is fixed on the baffle plate that has opening on the cylinder inboard wall between the stirring disc, the heating agent chuck of the cylindrical shell outside and the welding of end cap outer face, the charging aperture of the bottom solid welding of the close front end of cylindrical shell and cylindrical shell are near the discharging opening of the bottom solid welding of rear end, and the gas phase mouth of the cylindrical shell top solid welding of corresponding discharging opening constitutes; Bottom near an end end cap is provided with anti-blocking liquid level gauge mouth, inserts liquid level gauge in the anti-blocking liquid level gauge mouth.

The front and rear cover center slightly is provided with the stirring axis hole to the bottom eccentric part.

Stir the open-celled structure that adopts gradual change successively on the disc.

The utility model is finished alcoholysis or hydrolysis with melt polycondensation high polymer old material at the comparatively pure melt that the physics method obtains under the cooperation of related system, homogenizing, decontamination, remove little molecule, the several technical process of reaggregation, help from having changed molecular chain structure in essence, removed the PVC that reclaims in the raw material, PP, polyolefin and derivative class organic impurities thereof such as PE, thereby the purity and the quality of regenerative raw materials have been improved, the polyester fondant of Xing Chenging is in uniformity thus, impurity content and final quality just are higher than these indexs of raw material far away, thereby be widely used in the POY long filament, three-dimensional hollow, FDY, nonwoven, in strong industry silk, regeneration bottles etc. are to reclaiming the higher occasion of raw material quality requirement, minimizing realizes recycling economy to the demand and the consumption of petroleum resources of former raw material.The utlity model has following beneficial effect:

(1) adaptability to waste and old raw material is strong, can process extremely greatly to count markets and reclaim waste and old raw material and produce high-quality raw product again;

(2) core of the present utility model is homogenizing reaggregation process, has solved the quality problem of non-uniform between the raw material of separate sources, and the raw material same with the physics method handled through the utility model, can produce the product that quality is more stable, quality is higher;

(3) the utility model macromolecule melt quality of producing can online adjustment quality index, and steady production, satisfies the different industries quality requirement different to of a sort raw material;

(4) present technique is follow-up can use by supporting direct melt continuously, and does not need regeneration to produce middle product (high polymer particle), reduces production process and energy consumption.
