Description

Technical Field

[0001] The utility model belongs to the technical field of road engineering, and in particular relates to a municipal road solid waste classification and recycling device. Background Art

[0002] In the context of urban renewal, the maintenance and renovation of municipal roads have entered a peak period. A large amount of old road milling materials have become road solid waste, which not only pollutes the environment, but also causes a large amount of resource waste. At present, the utilization of old road milling materials is limited to recycling. However, due to various problems such as the poor mechanical properties of the milling materials themselves and the excessive amount of admixture that cannot meet the use requirements, only a small amount of milling materials can be recycled, the utilization rate is low, and the waste is too large. The existing recycling methods basically do not perform special treatment on the milling materials. The recycled milling materials are not only of poor quality, but also extremely difficult to use. Asphalt is a non-renewable fossil energy. In some areas, stone materials are scarce and the purchase cost is high. If the old road milling materials can be used efficiently and the aggregates can be classified and recycled, it will greatly solve the problem of resource waste and environmental pollution. In view of this situation, there is an urgent need for a municipal road solid waste classification and recycling device. Utility Model Content

[0003] The purpose of the utility model is to provide a municipal road solid waste classification and recycling device to solve the problem of poor recycling quality in existing recycling methods.

[0004] The technical solution of the utility model is: a municipal road solid waste classification and recycling device, including a vehicle body, in which a crushing device, a first stirring drum and a second stirring drum connected in sequence are provided, a heating plate is provided in the first stirring drum, a plurality of holes are opened in the middle of the side wall of the first stirring drum, an asphalt collection box is provided below the first stirring drum, a screen is provided in the middle of the side wall of the second stirring drum, a fine aggregate collection box is provided below the second stirring drum, and a coarse aggregate collection box is provided at the rear end of the second stirring drum.

[0005] As a further improvement of the present invention, the crushing device includes a feed hopper and a crushing roller, and the crushing roller is relatively arranged at the lower end of the feed hopper.

[0006] As a further improvement of the present invention, the crushing device and the first stirring drum are connected via a first conveyor belt.

[0007] As a further improvement of the present invention, the first stirring drum and the second stirring drum are connected via a second conveyor belt.

[0008] As a further improvement of the present invention, a fan is provided above the second conveyor belt.

[0009] The beneficial effects of this utility model are as follows: A crushing device, a first mixing drum, and a second mixing drum are installed within the vehicle body. Road solid waste is first crushed and then enters the first mixing drum for heating. The asphalt melts and flows out through the holes and is collected in the asphalt collection box. The remaining solid waste enters the second mixing drum, where fine aggregate is screened out and collected in the fine aggregate collection box. Coarse aggregate is discharged from the rear end of the second mixing drum and collected in the coarse aggregate collection box. After a series of treatments, the asphalt, fine aggregate, and coarse aggregate are separated and recycled. The waste asphalt is fully recycled by adding a modifier, and the recycled aggregate is also taken to the material yard as new aggregate for remixing and reuse. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0012] The present invention will be described in detail below with reference to the accompanying drawings.

[0013] like Figure 1 As shown, a municipal road solid waste classification and recycling device includes a body 1, in which a crushing device 2, a first mixing drum 3 and a second mixing drum 4 connected in sequence are provided. A heating plate 31 is provided in the first mixing drum 3, and a plurality of holes 32 are opened in the middle of the side wall of the first mixing drum 3. An asphalt collecting box 5 is provided below the first mixing drum 3, a screen 41 is provided in the middle of the side wall of the second mixing drum 4, a fine aggregate collecting box 6 is provided below the second mixing drum 4, and a coarse aggregate collecting box 7 is provided at the rear end of the second mixing drum 4.

[0014] The crushing device 2 includes a feed hopper 21 and a crushing roller 22 , and the crushing roller 22 is relatively arranged at the lower end of the feed hopper 21 .

[0015] The crushing device 2 and the first stirring drum 3 are connected via a first conveyor belt 8 .

[0016] The first stirring drum 3 and the second stirring drum 4 are connected via a second conveyor belt 9. A fan 10 is provided above the second conveyor belt 9.

[0017] Road milling material enters the feed hopper 21, is crushed by the crushing rollers 22, and then transported to the first mixing drum 3 via the first conveyor belt 8. Inside the first mixing drum 3, the material rotates and stirs while being heated by the heating plate 31. The melted asphalt flows through the holes 32 below and into the asphalt collection box 5, recycling the waste asphalt. The deasphalted, dry aggregate then passes through the second conveyor belt 9 and enters the second mixing drum 4. During this transport, the fan 10 above the second conveyor belt 9 blows away dust. As the aggregate rotates and stirs in the second mixing drum 4, fine aggregate leaks through the mesh of the screen 41 and is collected in the fine aggregate collection box 6. Finally, the remaining coarse aggregate enters the coarse aggregate collection box 7. This completes the sorting and recycling of road solid waste. The waste asphalt is fully recycled by adding a modifier, and the recovered aggregate is then returned to the material yard as new aggregate for remixing.
