Description

Technical Field

[0001] The utility model relates to the field of polyphenylene sulfide processing, in particular to a hot water circulation washing device for polyphenylene sulfide purification. Background Art

[0002] In the production process of PPS (polyphenylene sulfide), the circulating pipeline filtration system plays a crucial role; especially in the transportation and recycling of the material mixture, the filtration system can effectively remove solid particles, impurities and pollutants in the fluid, ensuring the continuity of the production process and the product quality; however, the circulating pipeline filtration system faces some technical challenges and difficulties in practical applications;

[0003] First of all, during the circulation of the PPS material mixture, due to the characteristics of the material and the influence of operating conditions, it often contains a large amount of solid particles and impurities; the presence of these particles and impurities will not only affect the purity and quality of the product, but may also cause blockage and wear to the circulating pipeline and filtration equipment, reducing the operating efficiency and stability of the system;

[0004] To solve this problem, the circulating pipeline filtration system usually uses filter plates, filter meshes or filter elements and other filtration media for filtration; these filtration media can effectively intercept solid particles and impurities in the fluid, ensuring that the clean fluid continues to be recycled; however, as the filtration time goes by, the particles and impurities accumulated on the filtration media gradually increase, resulting in an increase in filtration resistance, a decrease in filtration efficiency, and even possible blockage.

[0005] Therefore, it is necessary to provide a new hot water circulation washing device for polyphenylene sulfide purification to solve the above technical problems. Summary of the Utility Model

[0032] The working principle of the hot water circulation washing device for polyphenylene sulfide purification provided by the present utility model is as follows:

[0033] The device efficiently purifies and washes polyphenylene sulfide by means of hot water circulation; at the beginning of operation, hot water enters the washing bin 1 through the water inlet pipe 2 to conduct the primary washing of polyphenylene sulfide; during the washing process, sewage and impurities are carried to one side of the washing bin 1 under the action of gravity and water flow, and enter the circulation bin 4 through the circulation pipe 3;

[0034] In the circulation pipe 3, a filter plate 5 is installed to intercept impurities in the sewage; to ensure the smoothness of the filter plate 5, a scraper 6 is installed on the inner wall of the circulation pipe 3; the rotation of the scraper 6 is realized through a transmission mechanism 7: when water flows through the water inlet pipe 2, the turbine 71 rotates accordingly, driving the driving bevel gear 72 to rotate, and then driving the transmission bevel gear 74 on the connecting shaft 73 to rotate; one of the transmission bevel gears 74 meshes with the driven bevel gear 75, thereby driving the driven bevel gear 75 and the scraper 6 connected to its axis to rotate inside the circulation pipe 3; the rotation of the scraper 6 scrapes off the blockages on the filter plate 5, keeping the filter plate 5 smooth;

[0035] The connection between the scraper 6 and the circulation pipe 3 is realized through a connection structure 8; an arc-shaped connecting piece 82 is provided in a notch 81 opened in the middle of the circulation pipe 3, and an arc-shaped limiting strip 84 on one side of the scraper 6 is slidably connected to a chute 83 on the inner wall of the arc-shaped connecting piece 82, enabling the scraper 6 to move along the inner wall of the circulation pipe 3 under the restriction of the connecting piece; at the same time, the arc-shaped connecting piece 82 is fixed to the circulation pipe 3 through bolts 85 and nuts 87, ensuring the stability of the connection;

[0036] To ensure the stable connection between the scraper 6 and the driven bevel gear 75, a conduit 9 is fixedly connected to the axis of the driven bevel gear 75, and a spring 10 is installed inside the conduit 9; one end of the spring 10 is connected to a push rod 11, and the other end of the push rod 11 is fixed to the scraper 6; this design enables the scraper 6 to have a certain buffer and self - adaptability when being impacted by water flow or blocked by impurities, ensuring the close fit between the scraper 6 and the filter plate 5;

[0037] The heating plate installed in the circulation bin 4 can control the temperature of the washing water and the circulating water, ensuring a constant temperature during the washing process; this temperature control helps to improve the washing effect and ensure the purification quality of polyphenylene sulfide;

[0038] After the washing process is completed, the waste water in the washing bin 1 can be discharged by opening the sewage outlet and valve at the bottom of the washing bin 1; at the same time, the cleaning and maintenance of the equipment become simple and fast, improving the overall use efficiency of the equipment.
