Description

Technical Field

[0001] The invention relates to the technical field of wastewater recovery, and in particular to a device and a method for recovering wastewater after yarn dyeing. Background Art

[0002] Organic matter and dyes in wastewater are the main pollutants. Treatment equipment can effectively remove these harmful substances through physical, chemical or biological methods, such as activated carbon adsorption, precipitation, filtration, etc., thereby reducing their harm to the environment. With the continuous improvement of environmental protection requirements, the printing and dyeing industry needs to take the path of sustainable development. The popularization and application of wastewater treatment equipment can not only help enterprises meet environmental protection standards and reduce production costs, but also enhance the social image of enterprises and promote the healthy and sustainable development of the printing and dyeing industry.

[0003] Chinese patent CN117682574B proposes a printing and dyeing wastewater recovery and treatment device and a treatment method thereof. By setting a transducer cylinder, the printing and dyeing wastewater first enters the transducer cylinder after heat exchange treatment. The printing and dyeing wastewater entering the transducer cylinder passes through the filter plate and is preliminarily filtered through the filter net to filter the solid impurities inside. After passing through the filter plate, the printing and dyeing wastewater continues to move forward while impacting the paddle blades. The paddle blades rotate under the impact of the water flow. On the one hand, the filter plate is driven to rotate through the transmission shaft, so that multiple energy-generating balls inside the filter plate follow the rotation movement. The ball core inside the energy-generating ball rotates at high speed under the action of centrifugal force, and electricity is generated by the generator in the ball core and stored in an external storage device. On the other hand, the transmission shaft rotates while driving the first bevel gear to rotate. The first bevel gear and the second bevel gear are meshed and driven to drive the rotating shaft and the third bevel gear. The bevel gear rotates and meshes with the fourth bevel gear to rotate and generate electricity. The two power generation modes generate electricity synchronously, which significantly improves the energy conversion efficiency and saves energy. It solves the problem that the existing printing and dyeing wastewater recovery and treatment device only filters the wastewater, has low energy conversion efficiency and high treatment cost during the filtration process. During filtering, the filter disc rotates under the action of the blades and the transmission shaft. On the one hand, it can meet the power generation needs of the two power generation systems. On the other hand, the self-rotation of the filter disc can continuously disturb the water body, which can effectively prevent particles from accumulating on the surface of the filter disc and causing blockage. After the wastewater treatment is completed, the electric control valve in the impurity removal port is opened by the valve-controlled motor, and the particulate impurities filtered by the filter net in the energy conversion cylinder are cleaned by the exhaust equipment connected to the flexible air duct hose, and the impurities removal efficiency is high.

[0004] The above scheme cannot clean the surface of the filter, which may easily lead to clogging of the filter surface. The clogging will affect the recovery efficiency. It is also not convenient to replace the internal parts of the filter assembly. Replacement requires a large number of bolts, which is very troublesome and reduces the practicality of the wastewater recovery device after yarn dyeing. Summary of the invention
