[0002] The application of wastewater recycling systems in concrete production stems primarily from the need to conserve resources and protect the environment. Wastewater generated during concrete production typically contains solid particles such as cement and sand. Direct discharge can lead to water pollution and resource waste.

Sedimentation tanks rely on gravity to settle solids and have inlets, outlets, and sludge discharge ports. Filtration equipment filters or absorbs impurities in layers. Mixing equipment mixes chemicals with wastewater. Water storage equipment stores treated water and has water level monitoring devices.

[0004] When water flows into the sedimentation tank of the wastewater recycling device, the sediment is flushed out, which will cause the settled impurities to be re-suspended in the water, reducing the sedimentation effect, resulting in an increase in the load of the subsequent treatment process, affecting the treatment efficiency and water purification level of the entire wastewater recycling system; and the filter plate in the wastewater recycling device cannot be disassembled, which will cause blockage.

[0025] Reference Figure 3 and Figure 4 On the right side of the interior of the water tank 1, there are quartz sand filter plates 18 and activated carbon filter plates 19 sliding at equal intervals. The quartz sand filter plates 18 are mainly used to filter larger particles of impurities. The particle size of the quartz sand can be selected according to specific filtering requirements, such as 0.5-1.2mm. The frame of the filter plate can be made of stainless steel, such as 304 stainless steel, to ensure its structural strength and corrosion resistance. The activated carbon filter plate 19 is used to adsorb impurities such as organic matter in the water. Coconut shell activated carbon can be used as the activated carbon, which has a large specific surface area and adsorption performance. The filter plate frame can also be made of 304 stainless steel. Two convex grooves 13 are equidistantly provided on the middle side of the right side of the water tank 1. The inner bottom side of the convex groove 13 is fixedly connected to one end of the spring 22, and the other end of the spring 22 is fixedly connected to the lower middle side of the convex block 23.

It is made of transparent tempered glass, such as transparent tempered glass with a thickness of 5 mm, which has good transparency and strength and can withstand a certain pressure.

[0026] Working principle: First, wastewater enters the filter box 2 through the water inlet flange 6. Since the water wheel 10 is a component that rotates by the force of water flow, it is connected to the limit block 11 through the bearing 12. The wastewater hits the water wheel 10 to make it rotate during the flow, so as not to mix the sediment at the bottom of the filter box 2. Then, the bottom sediment is blocked with a quickly detachable baffle 15 for easy cleaning. The water outlet holes 16 are provided on the baffle 15 to allow the wastewater that has undergone preliminary treatment to flow out evenly from the small holes, thereby achieving uniform distribution of water flow and avoiding excessive local filtration pressure due to concentrated impact of water flow;

[0027] The operator can easily pull the convex block 23 located within the convex groove 13 using the pull rod 24. This action releases the engagement between the locking rod 26 and the quartz sand filter plate 18 and the activated carbon filter plate 19. The quartz sand filter plate 18 and the activated carbon filter plate 19 are then removed from the water tank 1 using the specially designed pull rod 24 for cleaning. After cleaning, the quartz sand filter plate 18 and the activated carbon filter plate 19 are returned to the water tank 1. When closed, the spring 22 attached to the bottom side of the convex groove 13 generates a spring force that pushes the convex block 23, causing the locking rod 26 on the pull rod 24 on the right side of the convex block 23 to automatically engage the cylindrical groove 27 of the quartz sand filter plate 18 and the cylindrical hole 28 of the activated carbon filter plate 19, quickly securing the convex block 23. In this process, two washers 25, equidistantly located on the right sides of the quartz sand filter plate 18 and the activated carbon filter plate 19, play a crucial role. The gasket 25 is made of a material with good sealing performance (such as nitrile rubber), which can effectively prevent water from leaking out from the gap between the filter plate and the wall of the water tank 1. This solves the problem that the filter plate is easily blocked due to its non-detachable nature, which in turn leads to increased operating costs.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
