Description

Technical Field

[0001] This utility model relates to the technical field of dyeing wastewater processing, and in particular to a dyeing wastewater recycling device. Background Technology

[0002] Dyeing and printing wastewater refers to the wastewater discharged from dyeing and printing factories that process cotton, linen, chemical fibers and their blended products, silk, wool dyeing and finishing factories, and silk factories. The wastewater contains dyes, sizing agents, auxiliaries, oils, acids and alkalis, fiber impurities, sand, inorganic salts, etc.

[0003] Extensive research revealed Chinese patent publication number CN208577488U, which discloses a device for the in-situ recycling of tanning and dyeing wastewater from leather production. The technical problem this invention aims to solve is the inconvenience of maintaining the stirring device inside the reaction tank. To address this issue, a device for the in-situ recycling of tanning and dyeing wastewater from leather production is provided. This device includes a reaction tank with supporting legs fixedly connected to its bottom. A discharge valve is fixedly connected to the outlet at the bottom of the tank. A cover is installed on the top of the tank, and first fixing sleeves are fixedly connected to both sides of the cover. Movable plates are movably fitted inside each of the first fixing sleeves. This device facilitates the separation of the reaction tank from the cover, allowing workers to easily inspect and maintain the internal stirring block, ensuring greater stability during rotation and extending the service life of both the reaction tank and the stirring block.

[0004] In summary, existing dyeing wastewater treatment devices typically use filter screens or filter cartridges that are fixedly installed inside the tank, making disassembly and replacement very troublesome. Furthermore, the filtration efficiency of the filter screens or filter cartridges will be significantly reduced over long-term use.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a dyeing wastewater recycling device, which would make it more valuable for industrial use. Utility Model Content
