Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment devices, and in particular to a device for treating wastewater from reactive dyeing. Background Technology

[0002] Knitted products are called textiles after they have been processed and woven. Knitted textiles need to be dyed to form beautiful patterns and colors before they can be sold on the market. During the dyeing process of knitted textiles, a large amount of wastewater is generated. If this wastewater is discharged without purification treatment, it will affect the surrounding environment. Therefore, this wastewater needs to be specially treated before it can be discharged.

[0003] Dyeing wastewater contains large amounts of pollutants such as dyes and auxiliaries. Direct discharge will color the water, reduce its transparency, and affect the photosynthesis and living environment of aquatic organisms. It may also contain harmful substances such as heavy metals, causing long-term damage to the ecosystem. After treatment, pollutants can be effectively removed, reducing pollution to water bodies, soil, and other environmental elements, and protecting the ecological balance.

[0004] Dyeing wastewater treatment is a crucial aspect of the green development of the textile printing and dyeing industry. In related technology, application number CN202420232855.6 discloses a dyeing wastewater treatment device. This device uses a conical filter plate to separate textile threads and impurities from the wastewater, preventing impact on subsequent processes and improving wastewater treatment efficiency. However, during operation, when separating textile threads, impurities and threads are trapped together at the top of the conical filter plate, causing blockages. The filter plate needs to be removed and cleaned frequently. If treating large volumes of dyeing wastewater, this necessitates frequent cleaning, significantly impacting treatment efficiency.

[0005] Therefore, it is necessary to provide a reactive dye dyeing wastewater treatment device to solve the above-mentioned technical problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 A device for treating wastewater from reactive dyeing includes: a base plate 1, a filter assembly 2 disposed on the left side of the top of the base plate 1, and an acid-base neutralization assembly 3 disposed on the right side of the top of the base plate 1.

[0023] The filter assembly 2 includes a filter box 21 located on the top left side of the base plate 1. The top of the filter box 21 is provided with a water inlet 22.

[0024] The bottom of the inlet 22 is set separately. When the wastewater is discharged from the top, it will flow to the top of the two filter plates 25. Under the action of the two filter plates 25, the textile threads and impurities will remain on the top of the filter plates 25, while the wastewater will flow through the filter plates 25 to the bottom of the filter box 21. During this process, since the filter plates 25 are set at an angle, the textile threads and impurities will gradually roll into the two collection frames 27 under the continuous impact of the water flow above and be collected.

[0026] The exhaust gas treatment cylinder 34 includes an exhaust fan and two purification adsorption plates, which can treat the harmful exhaust gases generated during acid-base neutralization.

[0027] Two support springs 26 are provided on the inner side of the placement plate 23 and on the peripheral side of the two sets of limiting rods 24 respectively. The opposite ends of each pair of support springs 26 are fixedly connected to the upper and lower sides of the two filter plates 25 respectively.

[0028] Collection frames 27 are provided on both the left and right sides of the inner wall of the filter box 21, which can slide back and forth. Fixing blocks 28 are provided on the inner side of the filter box 21 and on the opposite side of the two collection frames 27. A first telescopic sleeve 29 is provided on the top of each of the two fixing blocks 28. A second telescopic sleeve 4 is provided on the top of each of the two first telescopic sleeves 29, which can slide up and down. The top of each of the two second telescopic sleeves 4 is fixedly connected to the bottom of the two filter plates 25 respectively.

[0029] The limit rod 24 and the two telescopic sleeves allow the filter plate 25 to move up and down inside the filter box 21. When the rotating cam 5 rotates, it drives the connecting strip 6 to rotate, which in turn causes the filter plate 25 to vibrate up and down continuously, which can improve the filtration effect and prevent impurities from clogging the filter holes. With the collection frame 27, it is not necessary to deal with the accumulated textile threads and impurities for a longer period of time.

[0030] The inner side of the filter box 21 is rotatably provided with two rotating protrusions 5. The two rotating protrusions 5 are rotatably provided with connecting strips 6 on their circumferential sides. The bottom of the two connecting strips 6 are respectively rotatably connected to the top of the two filter plates 25.

The top of the mixing chamber 31 is equipped with a mixing motor 35 for driving the mixing frame 32 to rotate, and the bottom of the mixing chamber 31 is equipped with a discharge port 36.

[0033] The stirring motor 35 drives the stirring frame 32 to rotate, thereby stirring the wastewater and solution inside, thus completing the treatment process of neutralizing the acid and alkali of the wastewater.

[0034] The working principle of the reactive dyeing wastewater treatment device provided by this utility model is as follows:

[0035] Step 1: When in use, wastewater is discharged from the top inlet 22. The wastewater will flow to the top of the two filter plates 25. Under the action of the two filter plates 25, the textile threads and impurities will remain on the top of the filter plates 25, while the wastewater will flow through the filter plates 25 to the bottom of the filter box 21. During this process, since the filter plates 25 are set at an angle, the textile threads and impurities will gradually roll into the two collection frames 27 under the continuous impact of the water flow above and be collected.

[0036] Step 2: The filtered wastewater is discharged into the mixing chamber 31 by the water pump 8. The cover is opened and the acid-base neutralization solution is poured into the feed port 33. After the cover is closed, the stirring motor 35 is turned on to drive the stirring frame 32 to rotate, thereby stirring the wastewater and solution inside, thus completing the acid-base neutralization treatment process of the wastewater.

[0037] Compared with related technologies, the reactive dyeing wastewater treatment device provided by this utility model has the following beneficial effects:

[0038] With the arrangement of two filter plates 25, textile threads and impurities will remain on the top of the filter plates 25, while wastewater will flow through the filter plates 25 to the bottom of the filter box 21. During this process, because the filter plates 25 are inclined, the textile threads and impurities will gradually roll into the two collection frames 27 under the continuous impact of the water flow above. With the arrangement of two collection frames 27, it is not necessary to deal with the accumulated textile threads and impurities for a longer period of time, thereby ensuring the wastewater treatment efficiency.
