Construction waste has a wide-ranging corrosive effect on our living environment. If construction waste is left unattended for a long time, it will have a detrimental impact on urban environmental sanitation, living conditions, and land quality assessment.

[0003] Currently, construction waste recycling on the market generally involves automatic or semi-automatic sorting of different materials such as concrete, bricks, metal, wood, and plastic. Large pieces of waste (such as concrete and stone) are broken down into small particles using crushers and pulverizers. Then, metals are separated using vibrating screens and magnetic separators, and wood and lightweight materials are manually screened out.

[0004] Currently, construction waste recycling equipment on the market often requires manual labor to separate wood from stones. However, manual sorting requires a large number of workers, is very labor-intensive, and has low efficiency and is not accurate. Therefore, a construction waste recycling device is proposed to solve the above problems. Utility Model Content

[0013] Reference Figures 1-4 The water circulation component includes a water pump 21, which is an ISG type vertical pipeline centrifugal pump. The water pump 21 is fixedly connected inside the water tank 1. A water pipe 13 is fixedly connected to the outlet of the water pump 21. A rectangular water inlet 5 is fixedly connected to the end of the water pipe 13 away from the water pump 21. The rectangular water inlet 5 is made of stainless steel perforated plate. A rubber ring 17 is fitted between the water pipe 13 and the rectangular water inlet 5 to seal and prevent leakage. A fan 16 is installed on the outside of the water tank 1. A duct 15 is fixedly connected to the air outlet of the fan 16. The end of the duct 15 away from the fan 16 is fixedly connected to the inside of the water tank 1. The fan 16 blows air into the bottom of the water tank 1 through the duct 15, increasing the buoyancy of the water in the water tank 1.

[0014] Reference Figure 1 , Figure 4 and Figure 5 The top of the water tank 1 is fixedly connected to the inlet 6, which is made of stainless steel plate and has a large size. The inclined angle of the inlet 6 ensures that the waste can slide in smoothly. The bottom of the inlet 6 is fixedly connected to the bracket 7. The surfaces of conveyor belt 1 2 and conveyor belt 2 3 are provided with multiple drainage holes 22, which are arranged in a quincunx pattern. This design can not only ensure the effective transportation of waste, but also allow the cleaning wastewater to seep out quickly. Collection box 1 9 and collection box 2 10 are set on the outside of the water tank 1. Collection box 1 9 is located below conveyor belt 1 2, and collection box 2 10 is located below conveyor belt 2 3. A scale 8 is fixedly connected inside the water tank 1. A drain valve 12 is fixedly connected to the outside of the water tank 1.

[0015] Working principle: First, add appropriate amount of water to water tank 1 according to scale 8. Then, start the equipment and add pre-treated construction waste into the equipment through inlet 6 supported by bracket 7. The construction waste will then fall into the water. Waste with low density and light weight will float on the surface and be conveyed to collection box 9 by conveyor belt 2, while waste with high density and heavy weight, such as stones, will sink and be conveyed to collection box 10 by conveyor belt 3. The water carried out by the conveyor belt will flow back to water tank 1 through the drain hole 22. During this process, the water pump 21 in water tank 1 continuously pumps water. Water is drawn from tank 1 through pipe 13 and then discharged back into tank 1 through rectangular inlet 5, creating forward water waves that push floating waste forward. Baffle 18 prevents floating waste from drifting onto conveyor belt 2 3. Meanwhile, fan 16 continuously supplies air to the bottom of tank 1 through duct 15, increasing buoyancy in tank 1 and making it easier for low-density waste to float. After the equipment is used, the water can be drained through drain valve 12 for treatment. Long plate 1 4 and long plate 2 24 prevent waste from falling from both sides during the conveying process.
