Description

Technical Field

[0001] The utility model relates to the field of dechlorination devices, in particular to a cleaning liquid dechlorination device. Background Art

[0002] With the prevalence of fast food culture, the use of various plastic packaging products has become increasingly frequent. For example, the use of disposable plastic packaging products such as plastic lunch boxes (PP, PS), milk tea cartons, and beverage bottles has increased significantly. However, due to the inherent chemical properties of the material, it is not easy to degrade. The large amount of discarded plastic waste has increased the environmental burden. Whether it is landfilled or incinerated, it will have a serious negative impact on the ecosystem. Relying solely on the degradation of plastic waste often takes a very long time. A safe, effective, and environmentally friendly method is to recycle and reuse the chemical materials.

[0003] Compared to new, unused materials, the degradation of recycled plastics is unavoidable, and the greater the impurities, the more severe the degradation. Plastic lunch boxes, in particular, often clog with food residue, grease, and other impurities, making them difficult to effectively reuse simply by recycling. Therefore, the plastic recycling process typically includes crushing, cleaning, and granulation, with cleaning being particularly crucial.

[0004] In plastic recycling, cleaning agents typically include alkali, detergents, salts, and other chemical reagents. Salting-out is also used to increase the reuse rate and efficiency of the water containing the cleaning agent. However, the water after salting-out typically contains a large amount of chloride ions. The excessive presence of these ions reduces the binding of sodium ions with sodium stearate during reuse of the water containing the cleaning agent, reducing cleaning efficiency.

[0005] Currently, the most practical and cost-effective solution for industrial cleaning water is to use activated carbon to absorb chloride ions from water. However, static activated carbon adsorption has certain drawbacks, as small particles accumulate on the surface of the activated carbon, reducing adsorption efficiency. Utility Model Content

[0006] The purpose of the utility model is to provide a cleaning liquid dechlorination device to reduce the adsorption of small particles in sewage on the surface of activated carbon and improve the dechlorination effect of the activated carbon.

[0026] The following is a more detailed description of the cleaning liquid dechlorination device of the present invention, with reference to a schematic diagram, which illustrates a preferred embodiment of the present invention. It should be understood that those skilled in the art may modify the present invention as described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as a general guide for those skilled in the art and not as a limitation of the present invention.

[0027] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the present utility model proposes a cleaning liquid dechlorination device, including a treatment box 1, an activated carbon box 2, a support spring 3 and a floating airbag 4.

[0029] Specifically, the bottom and top of the treatment box 1 are respectively provided with a sewage inlet 5 and a sewage outlet 6.

[0030] The activated carbon box 2 is movably disposed inside the treatment box 1 , and the activated carbon box 2 moves between the sewage inlet 5 and the sewage outlet 6 .

[0031] The support spring 3 is fixedly disposed between the activated carbon box 2 and the inner bottom surface of the processing box 1 , and the support spring 3 is used to elastically support the activated carbon box 2 .

[0032] The floating airbag 4 is arranged above the activated carbon box 2 , and a traction rope 7 is connected between the floating airbag 4 and the activated carbon box 2 .

[0033] In this embodiment, the sewage pipe is connected to the sewage inlet 5, while the sewage outlet pipe 6 is also connected to the sewage outlet 6. As sewage is added to the treatment tank 1, the floating airbag 4 floats in the sewage. As the sewage flows from the bottom to the top of the activated carbon tank 2, the chloride ions in the sewage are adsorbed and removed by the activated carbon 11.

[0034] At the same time, the flow of sewage drives the floating airbag 4 to float up and down, and the floating airbag 4 drives the activated carbon box 2 to move up and down through the traction rope 7. The impact of the water flow causes the small particles adsorbed on the surface of the activated carbon 11 to separate from the activated carbon 11. At this time, the contact area between the activated carbon 11 and the sewage is increased, and the dechlorination effect of the activated carbon 11 is enhanced.

[0035] In one embodiment, a transparent window (not shown) is provided on the sidewall of the treatment box 1, and a sludge discharge valve 8 is installed at the bottom of the treatment box 1. During the dechlorination process, on-site staff can observe the treatment status within the treatment box 1 through the transparent window. Furthermore, if a large amount of sludge is observed at the bottom of the activated carbon box 2 through the transparent window, the sludge discharge valve 8 can be opened to discharge the sludge.

[0036] Furthermore, the activated carbon box 2 includes a mesh box body 9 , a mesh box cover 10 and activated carbon 11 .

[0037] Specifically, the mesh box 9 is movably arranged inside the processing box 1 .

[0038] The mesh box cover 10 is detachably mounted on the mesh box body 9 , and the mesh box cover 10 is fixedly connected to the traction rope 7 .

[0039] The activated carbon 11 is disposed between the mesh box body 9 and the mesh box cover 10 , and the activated carbon 11 is used to remove chloride ions in sewage.

[0040] In this embodiment, the cleaning liquid flows upward from the bottom of the mesh box 9. When the cleaning liquid contacts the activated carbon 11, a chemical reaction occurs to remove the chloride ions in the cleaning liquid. Because the activated carbon 11 acts as a reactant, its consumption decreases during the chloride ion removal process, and it is necessary to regularly add activated carbon 11 to the mesh box 9.

[0041] Since the mesh box cover 10 and the mesh box body 9 are connected in a detachable manner, after opening the mesh box cover 10, activated carbon 11 can be directly added into the mesh box body 9. The mesh box cover 10 and the mesh box body 9 can be connected and fixed by bolts 12.

[0042] To ensure that the cleaning liquid below the mesh box 9 can fully react with the activated carbon 11, the sidewalls of the mesh box 9 are in close contact with the inner wall of the treatment box 1 and in sliding contact. As the cleaning liquid flows upward from the bottom of the mesh box 9, it can only pass through the small holes in the mesh box 9 and the mesh box cover 10. During this process, the cleaning liquid is able to fully contact the activated carbon 11, improving the chlorine removal effect.

[0043] It should be noted that the activated carbon 11 is coconut shell activated carbon. Coconut shell activated carbon is a type of irregularly sized, crushed carbon with high strength and the ability to be regenerated multiple times after saturation. Its notable features include high adsorption capacity and low resistance. This product is widely used in fixed or fluidized beds.

[0044] Furthermore, a plurality of support springs 3 are provided, and the plurality of support springs 3 are evenly distributed between the activated carbon box 2 and the bottom surface of the processing box 1 .

[0045] Specifically, when the support spring 3 is compressed to its maximum, the bottom of the activated carbon box 2 is higher than the sewage inlet 5. In this case, the cleaning liquid can fully pass through the bottom of the mesh box 9 and fully contact the activated carbon 11, thereby ensuring the dechlorination effect of the cleaning liquid.

[0046] Furthermore, a plurality of traction ropes 7 are provided, and the traction ropes 7 are evenly distributed between the activated carbon box 2 and the floating airbag 4 .

[0047] Specifically, when the sewage in treatment tank 1 reaches the height of sewage outlet 6, the floating airbag 4 applies an upward pull to the activated carbon tank 2 via the traction rope 7. After the cleaning liquid is dechlorinated and discharged from sewage outlet 6, the floating airbag 4 applies an upward pull to the activated carbon tank 2 via the traction rope 7. As the cleaning liquid flows upward from bottom to top, the floating airbag 4 is driven to float up and down.

[0048] At this point, the floating airbag 4, via the traction rope 7, pulls the activated carbon 11 upward and downward, removing small particles adsorbed on the surface of the activated carbon 11 through the water flow. This increases the contact area between the activated carbon 11 and the cleaning fluid, thereby improving the cleaning fluid's chlorine removal effectiveness. Furthermore, the upward traction provided by the floating airbag 4 on the activated carbon 11 reduces the compressive load on the support spring 3, thereby extending its service life.

[0049] Compared with the prior art, the present invention has at least the following beneficial effects:

[0050] The utility model utilizes the up and down fluctuation of the floating air bag when the sewage flows, and cooperates with the elastic support of the supporting spring to drive the activated carbon box to float up and down, which can effectively reduce the adsorption of small particles in the sewage on the activated carbon, thereby greatly improving the dechlorination effect of the activated carbon box.

[0051] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
