Description

Technical Field

[0001] This utility model relates to the field of POY yarn oiling, specifically a POY yarn oiling device for efficient oil recovery. Background Technology

[0002] In the production of POY (pre-oriented yarn), the oiling process is an indispensable and important step. It can effectively improve the smoothness, bundle cohesion, and antistatic properties of the yarn bundle, thereby ensuring the smooth progress of subsequent textile processing. However, traditional POY yarn oiling devices have many problems in terms of oil recovery, making it difficult to meet the modern production requirements for high efficiency, energy saving, and environmental protection.

[0003] Existing oil recovery devices have relatively simple structures, with only a single collection container and a lack of preliminary filtration. This results in the recovered oil containing impurities such as fiber debris and dust. These impurities not only affect the quality of the oil and reduce its reusability, but may also clog the oiling equipment, increasing maintenance costs and downtime, thus impacting production efficiency. Furthermore, many devices use fixed filter components in the fine filtration stage of the oil, which are inconvenient to clean and replace. When clogged, they require shutdown and disassembly, which is time-consuming and complex. At the same time, traditional devices rely on static separation to separate moisture from the oil, which is inefficient and makes it difficult to ensure that the moisture content of the recovered oil meets production requirements, thus affecting the oiling quality and product performance of POY yarn. Therefore, we propose a POY yarn oiling device for efficient oil recovery. Utility Model Content

[0060] Working Principle: During the POY yarn production process, the oiling roller of the oiling machine 1 applies oil to the yarn bundle. Excess oil drips down. The collection frame 2 is located below the oiling roller, with its open end facing the roller, to catch the dripping oil and complete the initial collection. The recovery structure inside the collection frame 2 then comes into play. The large opening end of the conical frame 4 faces the opening end of the collection frame 2. When the oil enters the conical frame 4, the filter cloth 8 performs preliminary filtration, intercepting larger impurities such as fiber debris and dust, while simultaneously absorbing the oil quickly and preventing splashing. The pre-filtered oil flows out through the filter plate 14 at the small opening end of the conical frame 4 and enters the centrifuge 6. The oil inlet of the centrifuge 6 corresponds to the filter plate 14. After entering the centrifuge 6, the oil is separated into oil and water under the centrifugal force generated by high-speed rotation, based on the density difference between oil and water. The separated oil flows out from the oil outlet of the centrifuge 6 and is transported towards the filter frame 3. After entering the filter frame 3, the filter absorbs the oil. Component 13 begins operation, performing fine filtration of the oil to further remove residual impurities and odors, bringing the oil to a reusable standard. It is then stored in filter frame 3 for reuse. Regarding cleaning the recycling structure, when filter cloth 8 needs cleaning, the sludge-separating plate 10 is inserted into the conical frame 4 through the strip hole 11, covering the circular hole of the overlapping plate 15. This closes the oil flow channel. The filter cloth 8 is then rinsed with a high-pressure water gun and cleaning fluid. Wastewater generated during rinsing is discharged through the drain pipe 7. A valve at one end of the drain pipe 7 inside the conical frame 4 controls wastewater discharge. After cleaning, the cleaning fluid is drained, the valve of the drain pipe 7 is closed, the sludge-separating plate 10 is removed, and the circular hole of the overlapping plate 15 is reopened to restore normal oil flow. Furthermore, the movable plate 12, located at the connection point between collection frame 2 and filter frame 3, allows for easy disassembly. When the device requires maintenance, the movable plate 12 is removed, facilitating inspection and maintenance of components such as the centrifuge 6, ensuring the stable operation of the entire device.
