Description

Technical Field

[0001] The utility model belongs to the technical field of polyester production, and in particular relates to a three-dimensional rapid drying device for polyester yarns. Background Art

[0002] At present, when making polyester yarn, the raw materials are first subjected to the melt spinning process, which means that the polyester raw materials are subjected to certain processing, and then enter the screw extruder for heating after pelletizing, wet slicing and other processes, and then spin-formed. The formed polyester yarn needs to be sprayed with water or cooled by water so that the polyester yarn can be quickly shaped. After cooling, the wet polyester yarn needs to be dried. In the existing technology, when drying the polyester yarn, it is twisted and reeled immediately after spin-forming, and then cooled by water, which results in a thicker diameter of the yarn bundle after twisting and reeling. During the drying process, the polyester yarns are always densely squeezed together, which easily leads to incomplete drying of the filaments in the middle part, which in turn affects the subsequent processing after winding. For this reason, we propose a polyester yarn production drying equipment. Summary of the Invention

[0013] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0014] Embodiment: A three-dimensional rapid drying device for polyester yarn, such as Figure 1-Figure 3 As shown, it includes a left air duct 1, a bottom air duct 2 and a right air duct 3, and the left air duct 1, the bottom air duct 2 and the right air duct 3 all include an air inlet end 4 and an air outlet end 5. The air inlet ends 4 of the left air duct 1, the bottom air duct 2 and the right air duct 3 are all opened in the same direction. The right side of the left air duct 1, the top surface of the bottom air duct 2 and the right side of the right air duct 3 are all provided with air outlets 6. The top of the bottom air duct 2 is symmetrically provided with two groups of air guide shells 7, and each group of the air guide shells 7 includes a plurality of air guide plates 8. The outlet of the air guide shell 7 is set upward, and a plurality of groups of roller assemblies are provided above the air guide shell 7. The plurality of groups of roller assemblies are equidistantly arranged above the air guide shell 7. Each group of roller assemblies includes two vertical connecting rods 9 and two guide rollers 10. Both ends of the two guide rollers 10 are rotatably connected to the bottom of the two vertical connecting rods 9. The two guide rollers 10 are aligned up and down, and a plurality of guide grooves 11 are equidistantly provided on the surfaces of the two guide rollers 10. The guide grooves 11 on the surfaces of the two guide rollers 10 correspond to each other.

[0015] An exhaust assembly is provided on the top of the left air duct 1, the bottom air duct 2 and the right air duct 3, and the exhaust assembly includes two dust hoods 12; an air collecting pipe 13 is provided between the tops of the two dust hoods 12; the two dust hoods 12 and the air collecting pipe 13 are interconnected.

[0016] The principle of the present invention is as follows: after the filament bundles are squeezed out of the screw machine and cooled and shaped through water, multiple strands of filament bundles are passed through the frontmost roller assembly in turn, and multiple groups of filament bundles are arranged on the guide roller 10. The position of the filament bundles is restricted by the guide groove 11 to avoid overlapping. The air inlet ends 4 of the left air duct 1, the bottom air duct 2 and the right air duct 3 are respectively connected to the heater, and the air collecting duct 13 is connected to the exhaust equipment. When the filament bundles pass through the left air duct 1, the bottom air duct 2 and the right air duct 3, the hot air blown out from the air outlet 6 dries the filament bundles from three opposite directions, which can improve the drying effect of the filament bundles. The upward floating hot air can be collected by the exhaust assembly and recycled and utilized in the same way as the external waste heat recovery device to dry the filament bundles. The air guide plate 8 provided in the air guide shell 7 can evenly guide the hot air blown out of the bottom air duct 2 to the filament bundles arranged on the guide roller 10.
