Description

Technical Field

[0001] The utility model relates to a drying device, in particular to a drying device for polyester filaments. Background Art

[0002] Polyester filament is made of polyester. Polyester is an important variety of synthetic fiber and the trade name of polyester fiber in my country. It is made of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) as raw materials, and is made of polyethylene terephthalate (PET) through esterification or ester exchange and polycondensation reaction. The fiber is made through spinning and post-processing.

[0003] Existing polyester filaments generally need to be cleaned and dried during production to obtain relatively clean polyester filaments; the polyester filaments are generally cleaned first and then dried by a drying device; the existing polyester filaments are generally contaminated with a small amount of clean water after cleaning. If they are directly dried, their drying efficiency is slow. Therefore, a drying device that can first remove the clean water contaminated on the polyester filaments and then dry the polyester filaments is what we need, which can improve the drying efficiency of the polyester filaments. Utility Model Content

[0004] The utility model aims to solve the technical problem of providing a drying device which can first remove the clean water contaminated on the polyester filaments and then dry the polyester filaments.

[0005] In order to solve the above technical problems, the technical solution of a drying device for polyester filaments in the utility model is:

[0006] It comprises a frame, the front side of the frame is rotatably connected with an inlet roller, the rear side of the frame is rotatably connected with an outlet roller, and the frame is also connected with a conductor roller; a water absorbing device for absorbing water from polyester filaments is connected between the conductor roller and the inlet roller of the frame, and a drying mechanism is connected between the conductor roller and the outlet roller of the frame; the water absorbing device comprises a water-absorbing cotton swab, a connecting shaft and an end cover; the connecting shaft is integrated with the frame; the water-absorbing cotton swab is rotatably connected to the connecting shaft and is limited by the end cover; the end cover is detachably connected to the connecting shaft; the drying mechanism comprises a hot air blower and a spiral drying pipe; an air outlet is provided on the spiral drying pipe, and the spiral drying pipe is connected to the hot air blower.

[0007] A fixed panel is connected below the frame; the hot air blower is installed on the fixed panel.

[0008] A main pipeline is connected between the hot air blower and the spiral drying pipeline; the hot air blower is connected to the main pipeline through a connecting pipe, and the spiral drying pipeline is connected to the main pipeline; and a plurality of spiral drying pipelines are connected to the main pipeline.

[0009] The main pipeline is connected to seven spiral drying pipelines which are arranged at equal distances in the transverse direction.

[0010] The frame is provided with two water absorbing devices for removing water from the upper and lower sides of the polyester filaments respectively.

[0011] The end cover is threadedly connected to the connecting shaft.

[0012] The technical effect achieved by the utility model is as follows: the utility model connects a water absorbing device for absorbing water from the polyester filaments between the wire roller and the inlet roller of the frame. During the drying process of the polyester filaments, the polyester filaments are first introduced by the inlet roller, and then the clean water contaminated by the polyester filaments is removed by the water absorbing device. Then, the polyester filaments are guided by the wire roller to enter the drying mechanism, and after being dried by the drying mechanism, they are finally discharged by the outlet roller. Before drying the polyester filaments, the utility model first removes the clean water contaminated by the polyester filaments, so the subsequent drying process is faster and the drying efficiency is higher.
