Different material properties of municipal solid waste,

Integrated design scheme on intelligent waste crushing and processing system

I. System design principles

Aiming at the different material characteristics of municipal solid waste, industrial waste, electronic waste, etc., the modular customized design concept is adopted.

Recycling equipment for beverage bottles (plastic bottles) and glass bottles is categorized into various types depending on the material and processing needs.

Through the preliminary analysis of material composition (moisture content, hardness, density and other parameters), the use of ANSYS simulation technology for crushing stress simulation, and the construction of multi-dimensional mathematical models to ensure that the selection of equipment and process routes accurately match.

Second, the core processing equipment

1. Twin-shaft shear shredder
Adopting PLC intelligent control system, equipped with adjustable torque sensor, the processing capacity is up to 5-50 tons/hour.

The knife shaft is made of SKD11 mold steel, the surface is treated by supersonic flame spraying, and the hardness is above HRC60.

The unique V-shaped knife group design can realize 360° dead angle free crushing, and the discharged material size is controlled at 50-150mm.
2. Impact Crusher
is equipped with hydraulic overload protection system, and the built-in wear-resistant lining plate is made of high chrome cast iron.

Crusher: hammer blade striking crushing mainly, suitable for crushing branches, logs, etc., with high output and large crushing ratio.

With frequency conversion speed control technology to achieve dynamic adjustment of the discharge size (10-80mm), equipped with airflow classification system to improve crushing efficiency, unit energy consumption reduced by more than 15%.

Auxiliary process system

1. Pre-treatment module
contains automatic feeder (capacity 80t/h), magnetic separator (iron recovery rate ≥98%), eddy current sorter (non-ferrous metal recovery rate ≥95%), tumbler screen (screening efficiency ≥90%) and other equipment, to achieve the preliminary sorting of materials and de-contamination. 2.
2. Conveying system
adopts modular belt conveyor design, equipped with anti-running device and automatic tensioning system. According to the characteristics of different materials, it can be equipped with special materials such as high temperature resistant (-40℃~200℃), acid and alkali resistant conveyor belts, and the conveying inclination can reach 30°.
3. Environmental protection treatment unit
Integrated pulse bag filter (dust removal efficiency ≥99.9%), UV photo-oxidation catalytic exhaust gas treatment device (VOCs removal rate ≥90%), sewage treatment system (using A/O process, the effluent water reaches Class A standard), to ensure that the whole process of green production.

Intelligent control system
adopts Industrial Internet of Things (IIoT) technology to realize real-time monitoring of equipment status through distributed control system (DCS).

Configured with AI fault diagnosis system, predictable maintenance cycle is shortened by 40%.

The production data is accessed to the cloud platform, supporting remote operation and maintenance and big data analysis, and the utilization rate of resourcefulness is increased to more than 92%.

Through the intelligent design of the whole process, this system can realize the large-scale production with an average daily processing capacity of 300-2000 tons, which meets the demand for solid waste resource treatment under different application scenarios and is in line with the guidelines for the construction of national “Waste-Free Cities”.
