Description

Technical Field

[0001] This utility model relates to the field of waste treatment, and in particular to a sorting machine for municipal solid waste treatment. Background Technology

[0002] In traditional municipal solid waste treatment processes, landfill and incineration are the main terminal disposal methods. While landfill is relatively inexpensive, it occupies a large amount of land resources, and leachate can cause long-term pollution to the surrounding soil and water bodies. However, the high moisture content of kitchen waste in unsorted waste reduces incineration efficiency and increases energy consumption. Furthermore, the combustion of plastics, rubber, and other components may release toxic and harmful gases such as dioxins, posing a threat to the atmospheric environment and human health. Therefore, waste sorting, as a key upstream link in the municipal solid waste treatment chain, directly determines the effectiveness of subsequent treatment processes and the resource recycling rate through its efficiency and accuracy.

[0003] A search revealed that Chinese Patent Publication No. CN222901231U discloses a sorting machine for municipal solid waste treatment. Inside the housing, a first sorting mechanism and a second sorting mechanism are installed. When waste falls into the housing, it undergoes initial sorting through the large-diameter filter holes of the second sorting mechanism. Larger pieces of waste are stored inside the second sorting mechanism, while smaller pieces fall and are sorted into the first sorting mechanism. Waste falls into both the first and second sorting mechanisms, and the waste sorted from the first sorting mechanism is discharged through the housing's outlet, achieving multiple sorting operations and ensuring the smooth operation of the waste treatment process.

[0004] In the above-mentioned technical solution, the waste is sorted through a two-stage sorting mechanism. However, the two sorting mechanisms may not move in sync. For example, the second sorting mechanism may swing too fast while the first sorting mechanism moves too slowly, resulting in a large difference in the time the waste stays in the container. Some waste may fall out before being fully sorted. Alternatively, the sorting rhythms of the two mechanisms may not match, making it impossible to form a stable and consistent sorting process and affecting the stability of the overall sorting effect. Therefore, a sorting machine for municipal solid waste treatment is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a sorting machine for municipal solid waste treatment, including a sorting box 1. A mounting frame 2 is fixedly connected to the outer wall of the sorting box 1. A drive motor 3 is fixedly connected to the outer wall of the mounting frame 2. A conveyor roller 4 is fixedly connected to the output end of the drive motor 3. Four sets of conveyor rollers 4 are arranged, with each set connected to two sets of conveyor belts 5 in pairs. The outer wall of the conveyor rollers 4 is connected to the conveyor belts 5 via a transmission connection. The conveyor belt 5 at the top of the sorting box 1 is longer than the conveyor belt 5 at the bottom, allowing for waste separation during discharge. This facilitates guiding waste with different sorting results to different collection areas, preventing mixing. A notch 14 is provided through the outer wall of the sorting box 1, fitting onto the outer wall of the conveyor belts 5. The notch 14 facilitates the conveyor belts 5 removing waste from the sorting box 1. Two ends of a connecting rod 11 are rotatably connected to a first sorting frame 9 and a second sorting frame 12 via a rotating shaft 8, respectively, to achieve… The linkage of the two sorting frames ensures synchronized movement and improves sorting consistency. The outer wall of the conveyor roller 4 is connected to the transmission belt 6 via the transmission wheel. The transmission belt 6 drives the conveyor roller 4 to rotate via the transmission wheel. The top of the sorting box 1 is fixedly connected to the electric push rod 7, which provides power for the swing of the sorting frame 9 and can precisely control the angle adjustment of the sorting frame. The inner wall of the sorting box 1 is rotatably connected to the sorting frame 9, so that the sorting frame 9 can swing flexibly around the connection point, which is convenient for adjusting the screening angle to adapt to different waste characteristics. The outer wall of the sorting frame 9 has a straight groove 10. The surface of the sorting frame 12 also has a straight groove 10. The inner wall of the straight groove 10 is rotatably connected to the rotating shaft 8. The output end of the electric push rod 7 is rotatably connected to the outer wall of the rotating shaft 8. The outer wall of the rotating shaft 8 is rotatably connected to the connecting rod 11, which transmits the movement of the sorting frame 9 to the sorting frame 12, realizing the coordinated action of the two.

[0032] Reference Figures 1-3The inner wall of the sorting box 1 is rotatably connected to the sorting frame 2 12. The outer wall of the sorting frame 2 12 is also provided with a straight groove 10 and a rotating shaft 8. The two ends of the connecting rod 11 are rotatably connected to the sorting frame 1 9 and the sorting frame 2 12 through the rotating shaft 8 respectively. The outer walls of the sorting frame 1 9 and the sorting frame 2 12 are respectively fixedly connected to a micro vibration motor 13, which accelerates the movement of waste on the screen surface through vibration and improves the screening efficiency. The sorting frame 1 9 and the sorting frame 2 12 are both set in a U-shape, and the U-shaped opening is set towards the side of the conveyor belt 5. The bottom of the sorting frame 1 9 and the sorting frame 2 12 are provided with screen holes distributed at equal intervals, and the diameter of the screen hole of the sorting frame 1 9 is larger than the diameter of the screen hole of the sorting frame 2 12.

[0033] Reference Figure 4 The inner walls of sorting frame 19 and sorting frame 212 are both fixedly connected to fixed pipes 15. The inner walls of fixed pipes 15 are fixedly connected to air jet pipes 16. Multiple sets of air jet pipes 16 are arranged downwards, which can transmit the air source to the surface of the screen holes and spray high-pressure gas evenly onto the waste in the sorting frame to separate light impurities and assist in cleaning the screen holes. The inner walls of fixed pipes 15 are fixedly connected to air pumps 19 through connecting pipes 18. The outer walls of air pumps 19 are fixedly connected to the outer walls of sorting box 1. The inner walls of fixed pipes 15 are fixedly connected to transmission pipes 17. The transmission pipes 17 and connecting pipes 18 are partially retractable to adapt to the position changes when sorting frame 19 and sorting frame 212 swing, avoid damage to the pipeline due to pulling, and ensure the continuity of airflow.

[0034] Working principle: Waste falls into sorting frame 9 through the feed inlet of sorting box 1. The electric push rod 7 is activated, and its reciprocating motion, via the rotating shaft 8 and connecting rod 11, drives sorting frame 9 to tilt and vibrate regularly. Simultaneously, the micro-vibration motor 13 is activated to enhance the vibrating screening effect. Waste particles smaller than the screen holes of sorting frame 9 are screened out, while larger particles remain inside the frame and move along the U-shaped opening under vibration, eventually sliding onto the conveyor belt 5 below and being collected and discharged. Smaller particles screened out from sorting frame 9 continue to fall into sorting frame 1 below. 2. Under the same linkage mechanism and the action of its own micro-vibration motor 13, the waste in the second sorting frame 12 undergoes synchronous vibration screening and is retained within the second sorting frame 12. It then slides down along the U-shaped opening onto another conveyor belt 5 for centralized discharge. During the sorting process, the air pump 19 is activated, and the airflow passes sequentially through the connecting pipe 18, the retractable transmission pipe 17, and enters the fixed pipe 15, finally exiting at high speed from the jet pipe 16. The airflow blows towards the waste being screened, preventing screen clogging. After two stages of sorting and airflow cleaning, waste of different sizes falls onto the corresponding conveyor belts 5. All conveyor belts 5 are continuously operated under the control of the drive motor 3, transporting the sorted waste out of the sorting box 1, completing the entire sorting, collection, and discharge process.
