Embodiment Construction
[0015] Such as figure 1 It is a structural schematic diagram of the present invention, a drying device for differentiated polyester yarn raw materials, including a drying body 1, a heating plate 2 is fixed on the side wall of the inner cavity of the drying body 1, and a stirring device 3 is arranged in the middle of the inner cavity of the drying body 1, and the drying body 1. Exhaust devices 4 are provided on both sides of the top. The middle part of the top of the drying body 1 is provided with an inlet 5 for feeding raw materials. The side of the drying body 1 is fixedly connected with a drive motor 6.
[0016] When in use, put the raw materials into the drying machine body 1, rotate the stirring device 3 through the drive motor 6 to stir the raw materials, open the heating plate 2 at the same time to raise the room temperature of the inner cavity of the drying machine body 1, dry the raw materials, and then open the exhaust device 4, The water vapor from the drying process...

The invention relates to the technical field of differentiated polyester yarn production equipment, in particular to a differentiated polyester yarn raw material drying device. The differentiated polyester yarn raw material drying device comprises a dryer body; a heating plate and a stirring device are arranged in the dryer body; an exhaust device and a feed port are arranged at the upper end of the dryer body; and a driving motor is arranged on the side surface of the dryer body. In the differentiated polyester yarn raw material drying device, raw materials are put in the dryer body, and arestirred through rotation of the stirring device by the driving motor; meanwhile, the heating plate is opened to increase the room temperature of an inner cavity of the dryer body for drying the raw materials; and then, the exhaust device is started for exhausting water vapor generated by drying out of the inner cavity of the dryer body, so that the dryness of the raw materials is guaranteed, the crystallization degree and the softening point of the raw materials are further effectively improved, and the softening cementation caused by lower softening point in subsequent treatment process is prevented.
Description
technical field [0001] The invention relates to the technical field of differential polyester yarn production equipment, in particular to a differential polyester yarn raw material drying device. Background technique [0002] In the process of producing differentiated polyester yarn, the polyester yarn raw material needs to be sliced and dried first. If the moisture in the raw material is not removed, it will cause the following adverse effects: 1. The raw material is prone to hydrolysis during subsequent melt extrusion , In turn, it is easy to form foaming during spinning, resulting in broken ends and filaments; 2, the crystallinity and softening point are relatively low, and it is easy to soften and bond during melt extrusion, thereby causing blockage. Contents of the invention [0003] In order to overcome the disadvantages of low crystallinity and softening point caused by the insufficient drying degree of the existing polyester yarn principle, the present invention ...
