Detailed Implementation

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-4 The embodiments of the present invention include: like Figures 1-4 The fabric dyeing wastewater treatment device shown includes: a wastewater tank 1, a floating frame 14, a turntable 5, an arc-shaped stirring block 2, a sliding seat 6, a one-way valve 3, and a filter screen 23. The floating frame 14 is vertically and vertically mounted above the wastewater tank 1. In this embodiment, mounting frames 12 are provided on both sides of the wastewater tank 1. The mounting frames 12 are provided with guide posts 10 that penetrate upward through the floating frame 14. The floating frame is provided with linear bearings 11 corresponding to the guide posts 10 to guide the floating frame 14 in raising and lowering.

[0019] In this embodiment, a lifting drive mechanism 13 is provided on one side of the mounting frame 12 to drive the floating frame 14 to move up and down. The lifting drive mechanism 13 adopts a hydraulic cylinder or an electric push rod. The lifting drive mechanism 13 is connected to a controller, and the lifting control is performed through the corresponding controller to adjust the height of the floating frame 14.

[0020] The slide block 6 is movably mounted on the floating frame 14 along the length of the wastewater tank 1. In this embodiment, the floating frame 14 is provided with a slide rail 15 located at the bottom of the slide block 6 to guide the lateral movement of the slide block 6.

[0021] like Figure 1 As shown, the floating frame 14 is provided with a linear drive mechanism 16 for driving the slide block 6 to move laterally. In this embodiment, the linear drive mechanism 16 adopts a synchronous belt type linear module or a ball screw type linear module. The linear drive mechanism 16 is connected to a controller, and the controller is used to control the reciprocating linear movement.

[0022] A reduction gearbox 8 is mounted on the slide block 6. A rotating shaft 9 extends downwards from the bottom of the reduction gearbox 8 into the wastewater tank 1. A motor 7 is mounted at the input end of the reduction gearbox 8 to rotate the rotating shaft 9. The motor 7 can be speed-controlled via a controller and a frequency converter, allowing for speed adjustment of the rotating shaft 9 to adapt to different processes.

[0023] The turntable 5 is concentrically positioned at the bottom of the rotating shaft 9. In this embodiment, the turntable 5 is provided with a sleeve 4 that is connected to the rotating shaft 9. The sleeve is easy to insert and can be locked with bolts to achieve synchronous rotation of the turntable 5 and the rotating shaft 9.

[0024] The arc-shaped stirring blocks 2 are arranged in a circular array at the bottom of the turntable 5. The turntable 5 is equipped with a first screw 17 that connects to the top of the arc-shaped stirring blocks 2, facilitating easy assembly and disassembly. In this embodiment, as... Figure 2 As shown, two arc-shaped stirring blocks 2 are used, which rotate with the turntable 5 to stir the wastewater.

[0025] like Figure 3 and Figure 4 As shown, a cavity 18 is provided in the arc-shaped stirring block 2. Several water inlets 21 communicating with the cavity 18 are provided at intervals at the front end of the arc-shaped stirring block 2. The one-way valve 3 is provided in the water inlet 21. During the rotation of the arc-shaped stirring block 2, wastewater is allowed to enter the cavity 18 in one direction through the one-way valve 3.

[0026] In this embodiment, the inlet 21 adopts a stepped hole, and a first pressure ring 19 is provided in the inlet 21 to press and fix the edge of the one-way valve 3. A second screw 20 is provided on the first pressure ring 19 to connect with the arc-shaped stirring block 2, which facilitates assembly and ensures structural stability. The one-way valve 3 can be a flanged rubber duckbill valve, which is corrosion-resistant, low in cost, and has a good anti-backflow effect.

[0027] like Figure 4 As shown, several water outlets 25 communicating with the cavity 18 are arranged at intervals at the rear end of the arc-shaped stirring block 2. The filter screen 23 is arranged in the water outlet 25. During the process of wastewater in the cavity 18 being discharged through the water outlet 25, the filter screen 23 is used to filter impurities, so that the impurities are retained in the cavity 18 and secondary pollution is avoided.

[0028] Specifically, the outlet 25 adopts a stepped hole, and a second pressure ring 22 is provided in the outlet 25 to press and fix the edge of the filter screen 23. A third screw 24 connected to the arc-shaped stirring block 2 is provided on the second pressure ring 22. The structure is stable, and different types of filter screens 23 can be replaced in different stages of the filtration process, from primary filter screen to high-efficiency filter screen, which is flexible in use.

[0029] In addition, a drain pipe 28 is provided at the bottom of the wastewater tank 1. A valve 26 and an activated carbon filter 27 are connected in series on the drain pipe 28. After the wastewater is filtered, it undergoes final filtration through the activated carbon filter 27 during the discharge process to prevent impurities from flowing out (leaving some behind).

[0030] Wastewater treatment process: like Figure 1 As shown, in the process of treating fabric dyeing wastewater, the filter screen 23 first adopts a primary filter screen. During the rotation and lateral movement of the arc-shaped stirring block 2, the filter screen 23 is used to perform preliminary filtration of the wastewater. Next, bleaching agent is added for decolorization, followed by flocculant to coagulate oxides in the wastewater. At this time, the arc-shaped stirring block 2 rotates at low speed and moves back and forth to ensure the coagulation effect. After coagulation is complete, the floating frame 14 is lifted, causing the arc-shaped stirring block 2 to detach from the wastewater surface. The cleaned arc-shaped stirring block 2 in the cavity 18 is replaced, and a high-efficiency filter screen is installed. Then, the floating frame 14 is driven to descend and reset. The arc-shaped stirring block 2 rotates at high speed and moves back and forth horizontally to achieve stirring and high-efficiency filtration of the wastewater. Finally, the valve 26 is opened, and the activated carbon filter 27 is used for final filtration during the wastewater discharge process. The wastewater can then be reused for secondary dyeing or further purified before being discharged after meeting the standards.

[0031] In summary, the fabric dyeing wastewater treatment device disclosed in this invention can filter wastewater, has a compact structure, occupies a small area, and reduces treatment costs.

[0032] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
