Description
Technical Field
[0001] This utility model relates to the field of polyester chip technology, specifically to a recycled polyester chip melt filtration device. Background Technology
[0002] Recycled polyester chip melt is a substance produced during the polyester recycling process. After polyester products (such as polyester fiber clothing, polyester plastic bottles, etc.) are recycled, they are pre-treated by washing, drying, crushing and other processes to make recycled polyester chips. When these chips are heated and melted, recycled polyester chip melt is formed.
[0003] A recycled polyester chip melt filtration device is used in the polyester recycling process when the melt may contain impurities, incompletely melted particles, etc. The device is mainly composed of filter chambers, filter screens or filter elements. When the melt flows through the filtration device, the filter screen will intercept these impurities, allowing pure melt to pass through, thereby improving the quality of the recycled polyester melt and ensuring that high-quality recycled polyester products are produced in subsequent processing.

[0036] Combination Figures 2-4A feed pipe 10 is slidably connected to the top left side of the lid 8. Slide plates 12 are fixedly connected to the front and rear ends of the top left side of the lid 8. The inner wall of the slide plate 12 is slidably connected to the feed pipe 10, allowing the feed pipe 10 to be installed. A snap-fit assembly, including a connecting pipe 1, is provided at one end of the slide plate 10. One end of the connecting pipe 1 is fixedly connected to the slide plate 12, allowing the connecting pipe 1 to be installed. A pull rod 2 is slidably connected to the other end of the connecting pipe 1. A top plate 17 is slidably connected to the inner wall of the connecting pipe 1.

[0037] Working principle: When material is added to the feed pipe 10, impurities and unmelted particles can be filtered out in the filter barrel 18. The melt passes through the filter barrel 18 and is discharged from the drain pipe 6. When impurities and unmelted particles block the inner wall of the filter barrel 18, the melt cannot be discharged. When the brake motor 9 is turned on, the output end of the brake motor 9 rotates, driving the rotating rod 14 and scraper 21 to rotate, which can scrape off the impurities adhering to the inner wall of the filter barrel 18, thus allowing the melt to be discharged smoothly. When the filter barrel 18 needs to be cleaned, the barrel cover 8 is removed, and then the filter barrel 18 is pushed to the rear end to remove the filter barrel 18, thereby cleaning the impurities and unmelted particles inside the filter barrel 18. When the feed pipe 10 needs to be replaced, the pull rod 2 is pulled, which will cause the top plate 17 to press the spring 16 along the second slide groove 15. When the pull rod 2 is disengaged from the insertion hole 11, the feed pipe 10 can be removed and replaced.
