Abstract

The invention discloses a high-performance polyester POY preparation device and method. The high-performance polyester POY preparation device comprises a vibration impurity removal device, a crystallization device, a drying device, a screw extrusion device, a filtering device, a melt metering pump, a heat preservation box, a spinning assembly, a side air blowing device, a filament guide device, anoiling device and a winding device, wherein a polyester slice is subjected to vibration and impurity removal; a melt is filtered through the filtering device and then is subjected to spinning; the whole process flow comprises twice filtering and impurity removal, so that the production quality of the polyester POY is improved. The high-performance polyester POY preparation device and method provided by the invention have the advantages of being reasonable in structure, convenient to use, high in finished product quality and the like, and effectively solve the problem that the conventional polyester POY production process does not involve screening of materials in a former procedure, so that impurities are easily doped in the raw materials, and the quality of the polyester POY is affected.

Description

technical field [0001] The invention relates to the technical field of polyester POY production, in particular to a high-performance polyester POY preparation device and method. Background technique [0002] Among the known technologies, polyester POY high-speed spinning is a new technology developed in the 1970s. Its production capacity is 6-15 times higher than that of conventional spinning. The combination of spinning and drawing processes reduces process losses. The most widely used spinning technology in polyester POY production. The existing polyester POY production mainly includes direct spinning and slicing spinning. Direct spinning means that the melt is directly transported to the spinning equipment without pelletizing, drying, extrusion and other processes, so the cost is saved, but the production is flexible. However, although there are several more processes in chip spinning, the equipment parameters are easy to adjust, and the varieties of products that can be...
