municipal solid waste sorting machine
With accelerated urbanization and rising living standards, the amount of municipal solid waste generated is increasing year by year, and “garbage siege” has become a serious challenge for many cities. Traditional landfill and incineration methods not only occupy a large amount of land resources but may also cause secondary pollution. Against this backdrop, source reduction and resource utilization have become the fundamental solutions for solid waste treatment, and the key prerequisite for achieving this goal is efficient and precise solid waste sorting.
I. The Necessity of Municipal Solid Waste Sorting
Municipal solid waste is “resources in the wrong place,” but its mixed state leads to a severe underestimation of its value, significantly increasing the difficulty and cost of treatment.
1. The Cornerstone of Resource Utilization: Only by effectively separating recyclable materials such as plastics, metals, paper, and glass can they enter the appropriate recycling channels, turning waste into treasure and reducing the exploitation of primary resources.
2. Alleviating End-of-Life Treatment Pressure: Effectively separating recyclables and organic matter can significantly reduce the amount of waste entering landfills and incinerators, extend the service life of facilities, and reduce environmental risks.
3. Policy Response: The nation is vigorously promoting the construction of “zero-waste cities” and the waste sorting system, setting clear targets for the resource utilization rate of solid waste. Efficient sorting is the hardware guarantee for achieving these policy goals.
II. Intelligent Sorting Solution: How We Transform “Mixed” into “Separated”
Guoxin’s intelligent municipal solid waste sorting machine integrates mechanical, sensing, artificial intelligence, and airflow control technologies to provide you with a fully automated and highly efficient sorting solution.
Workflow:
1. Uniform Feeding and Bag Breaking: Waste is uniformly fed to the crusher via a plate feeder, automatically breaking open bagged waste to release internal dispersed materials, preparing for subsequent fine sorting.
2. Intelligent Identification and Sensing: The dispersed materials enter the core sorting area. Here, we are equipped with multiple high-precision sensing systems:
Near-infrared spectral sensor: Accurately identifies different types of plastics (such as PET, PE, and PP) and paper.
Electromagnetic sensor: Effectively captures metallic substances such as iron and aluminum.
Visual Recognition System: Based on AI deep learning, it can recognize the shape, color, and even brand of materials, enabling more complex classification.
3. Precise Execution and Separation: Once the target material is identified, the control system issues instructions within milliseconds, driving the corresponding actuators:
High-Pressure Airflow Nozzles（Air Separator）: Used to sort lightweight plastics, paper, etc., by precisely spraying them into designated collection troughs.
Electromagnetic（Magnetic Separator）Catapults: Used to sort metals, ejecting them using a momentary strong magnetic field.
Robotic Arms（Smart waste sorting): At specific workstations, AI robotic arms can assist in sorting, grasping special or high-value items.
4. Sorted Collection and Discharge: Different categories of sorted materials enter the collection bin through different chutes or conveyors, are packaged(Waste Horizontal Hydraulic Baler), and then sent to downstream recycling companies, achieving a closed-loop cycle.
III. Advantages of Municipal Solid Waste Sorting
Our equipment is not just for sorting; it brings you comprehensive value enhancement.
Advantage 1: Extremely High Sorting Efficiency and Precision
Replacing a large amount of repetitive manual labor, overcoming the problems of fatigue and unstable efficiency in manual sorting.
Our Solution: The equipment operates continuously and stably 24 hours a day, with a sorting speed dozens of times faster than manual sorting and a purity of over 95%, significantly enhancing the economic value of recyclables.
Advantage Two: Significantly Improved Economic Benefits
High labor costs and low value of mixed waste.
Our Solution: Although it’s a one-time investment, in the long run, it significantly reduces labor costs and directly generates considerable economic benefits by sorting out high-purity, high-value recyclable resources, with a clear return on investment period.
Advantage Three: Improved Working Environment
Manual sorting is dirty, messy, and unsanitary, posing health and safety hazards and making recruitment difficult.
Our Solution: Achieves fully automated, enclosed operation. Operators do not need to contact waste directly; they only need to monitor from the control room, completely improving the working environment and solving the company’s difficulties in recruiting and retaining staff.
Advantage Four: High Flexibility and Intelligence
The complex and variable composition of waste makes it difficult for fixed procedures to handle.
Our Solution: Our AI-based vision system possesses self-learning capabilities, continuously optimizing its sorting algorithm through data accumulation to adapt to changes in waste composition across different regions and seasons. The modular design also allows for customized sorting solutions based on customer needs (e.g., specializing in plastics or RDF fuel preparation).
IV. Successful Application Scenarios
Our intelligent sorting system has been successfully applied in:
* Municipal solid waste sorting and treatment centers
