Description

Technical Field

[0001] This utility model belongs to the technical field of waste sorting devices, and relates to a waste sorting device for surface mud-containing waste in landfills. Background Technology

[0002] With the acceleration of urbanization, the amount of waste generated is increasing day by day. As one of the main methods of waste disposal, the treatment of surface sludge waste in landfills is crucial. Surface sludge waste usually contains a large amount of mud, sand, stones, plastics, paper and other components, which need to be effectively sorted for subsequent treatment and utilization.

[0003] Currently, existing landfill surface sludge sorting devices have some shortcomings in operation. For example, traditional sorting devices often use a single screening method, which cannot accurately sort waste of different particle sizes and densities, resulting in low sorting efficiency and poor sorting effect. At the same time, for waste with high sludge content, sludge and sand easily clog the screen holes, affecting the normal operation of the screening process and requiring frequent shutdowns for cleaning, increasing labor and equipment maintenance costs. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a sorting device for muddy waste on the surface of landfills.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] In the above-mentioned landfill surface mud-containing waste sorting device, the bottom of the drum screen is equipped with an undersize collection conveyor, and one end of the undersize collection conveyor is equipped with an undersize transfer conveyor.

[0011] In the above-mentioned landfill surface mud-containing waste sorting device, the integrated sorting machine includes a vibrating feeder, an air separator, and a discharge conveying mechanism. The vibrating feeder receives material from the magnetic separator and feeds the material evenly into the air separator through vibration. The air separator uses airflow to separate light and heavy substances in the material. The discharge conveying mechanism receives the light and heavy substances separated by the air separator.

[0012] In the above-mentioned landfill surface mud-containing waste sorting device, the discharge conveying mechanism includes a heavy material transfer conveyor and a light material transfer conveyor, and the output port of the integrated sorting machine is connected to the heavy material transfer conveyor and the light material transfer conveyor respectively.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, a landfill surface sludge-containing waste sorting device includes a frame, on which a feeding mechanism, a screening mechanism, and a magnetic separation mechanism 5 are installed. The feeding mechanism includes a chain plate feeder 1 and a feeding conveyor 2, with the output port of the chain plate feeder 1 connected to the input port of the feeding conveyor 2. The screening mechanism includes a drum screen 3 and a comprehensive separator 4, with the output port of the feeding conveyor 2 connected to the input port of the drum screen 3. The magnetic separation mechanism 5 is located between the drum screen 3 and the comprehensive separator 4, with the output port of the drum screen 3 connected to the input port of the magnetic separation mechanism 5, and the output port of the magnetic separation mechanism 5 connected to the input port of the comprehensive separator 4.

[0027] Furthermore, the magnetic separation mechanism 5 includes a suspended iron remover 6 and an oversize conveyor 7, wherein the suspended iron remover 6 is disposed above the oversize conveyor 7.

[0028] In this embodiment, the suspended magnetic separator 6 uses the electromagnet assembly 19 to magnetically adsorb and separate the passing material, effectively removing iron impurities from the waste. The oversize conveyor 7 then continues to transport the magnetically separated material forward for subsequent processing or classification.

[0029] Furthermore, the chain plate feeder 1 includes a drive motor 8, a drive sprocket 9, a driven sprocket 10, and a chain plate 11. The drive motor 8 is connected to the drive sprocket 9. A chain is fitted on the drive sprocket 9 and the driven sprocket 10. The chain plate 11 is provided on the chain. The drive motor 8 drives the drive sprocket 9 to rotate, thereby driving the chain and the chain plate 11 to convey materials.

[0030] In this embodiment, the chain plate feeder 1 can feed materials into the feeding conveyor 2 evenly and stably, avoiding material accumulation and blockage during the conveying process. The drive motor 8 provides stable power, and through the cooperation of the drive sprocket 9 and the driven sprocket 10, the chain and chain plate 11 can run smoothly, ensuring the continuity and reliability of material conveying.

[0031] Furthermore, the drum screener 3 includes a drum body 12, a screen, a drive device 13, and a support device 14. The screen is installed inside the drum body 12. The drive device 13 is connected to the drum body 12 and drives the drum body 12 to rotate. The support device 14 is used to support the drum body 12.

[0032] In this embodiment, the drum body 12 serves as the main component for screening. The screen installed inside can effectively screen the material and separate materials of different particle sizes. The drive device 13 is closely connected to the drum body 12, providing it with a continuous source of rotational power to ensure the continuity and efficiency of the screening process.

[0033] Furthermore, the bottom of the drum screener 3 is provided with an undersize material collection conveyor 25, and one end of the undersize material collection conveyor 25 is provided with an undersize material transfer conveyor 26.

[0034] In this embodiment, the undersize material collection conveyor 25 is used to collect fine materials after being screened by the drum screener 3. These materials fall onto the undersize material collection conveyor 25 through the screen mesh. The other end of the undersize material collection conveyor 25 is connected to the undersize material transfer conveyor 26, realizing the continuous collection and transfer of undersize materials.

[0035] Furthermore, the integrated sorting machine 4 includes a vibrating feeder 15, an air separator 16, and a discharge conveying mechanism. The vibrating feeder 15 receives material from the magnetic separator 5 and feeds the material evenly into the air separator 16 through vibration. The air separator 16 uses airflow to separate light and heavy substances in the material. The discharge conveying mechanism receives the light and heavy substances separated by the air separator 16.

[0036] In this embodiment, the vibration frequency of the vibrating feeder 15 ensures that the material can be fed into the air separator 16 uniformly and continuously, avoiding material blockage or accumulation. The air separator 16 utilizes the principle of airflow; by adjusting the intensity and direction of the airflow, it can accurately and effectively separate light and heavy substances in the material.

[0037] Furthermore, the discharge conveying mechanism includes a heavy material transfer conveyor 17 and a light material transfer conveyor 18, and the output port of the integrated sorting machine 4 is connected to the heavy material transfer conveyor 17 and the light material transfer conveyor 18 respectively.

[0038] Furthermore, the suspended iron remover 6 includes an electromagnet assembly 19, a suspension frame 20, and a control system. The electromagnet assembly 19 is mounted on the suspension frame 20, and the control system controls the energization and de-energization of the electromagnet assembly 19.

[0039] In this embodiment, the electromagnet assembly 19 generates a magnetic field when energized, which can adsorb ferromagnetic impurities in the material. When the control system receives a start signal, the electromagnet assembly 19 is energized, a magnetic field is generated, and the ferromagnetic impurities are adsorbed onto the surface of the electromagnet. When the control system receives a stop signal, the electromagnet assembly 19 is de-energized, the magnetic field disappears, and the ferromagnetic impurities fall off, thus achieving the purpose of iron removal.

[0040] Furthermore, the feeding conveyor 2 includes a conveyor frame 21, a conveyor belt 22, a drive roller 23, and a driven roller 24. The conveyor frame 21 is used to support the entire feeding conveyor 2. The conveyor belt 22 is wound around the drive roller 23 and the driven roller 24. The rotation of the drive roller 23 drives the conveyor belt 22 to transport materials.

[0041] Furthermore, the structures of the oversize conveyor 7, undersize collection conveyor 25, undersize conveyor 26, heavy material conveyor 17, and light material conveyor 18 are the same as those of the feeding conveyor 2.

[0042] The working principle of this utility model is as follows:

[0043] In use, the waste is first initially conveyed by the chain plate feeder 1 to ensure that the material can enter the feeding conveyor 2 evenly and stably. The material is then conveyed by the feeding conveyor 2 to the drum screen 3. Inside the drum screen 3, the material is separated by the screening action of the screen, and the material of different particle sizes is separated. The oversize material is conveyed to the magnetic separation mechanism 5 by the oversize material transfer conveyor 7, while the undersize material is collected and transferred by the undersize material collection conveyor 25 and the undersize material transfer conveyor 26.

[0044] The suspended iron separator 6 in the magnetic separation mechanism 5 uses an electromagnet assembly 19 to adsorb and separate magnetic substances from the material, effectively removing iron impurities from the waste. The material after magnetic separation is then conveyed to the integrated separator 4. Inside the integrated separator 4, a vibrating feeder 15 evenly feeds the material into an air separator 16, which uses airflow to separate light and heavy substances from the material. The separated light and heavy substances are collected and transferred via a light material transfer conveyor 18 and a heavy material transfer conveyor 17, respectively.
