Continuous Tree Waste Processing System for Power Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Municipalities face challenges in continuously shredding and processing tree waste into manageable pieces for efficient volume reduction and energy generation, as existing systems lack the capability to handle large wood sections and soil-saturated materials effectively.
Innovation Solution
A system comprising multiple shear stations with reciprocating blades and an indexing blade, coupled with a pulverizing station and furnace, converts tree waste into steam energy for electricity generation, while also producing mulch and wood ash, utilizing hammer mills for consistent shredding and a magnet station for metal removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple pay-loaders, excavator mounted scissor shears, trailer mounted tub grinders, multiple conveyor systems and laborers are used to process tree waste, then the tree waste can be processed into mulchable output product, but the system complexity and labor requirements increase significantly
Solution Approach 1:
The patent combines multiple separate processing functions (shearing, grinding, conveying, screening) into a single integrated continuous processing system. The system merges the capabilities of multiple pay-loaders, excavator mounted shears, trailer mounted grinders, and conveyor systems into one unified apparatus that processes tree waste continuously from input to output without requiring separate equipment for each function.
Solution Approach 2:
The processing system is designed to handle multiple types of tree waste materials (branches, logs, stumps, roots) with varying sizes and conditions through a single multi-functional apparatus. The system can process different material types and deliver different output products (mulch, chips, shredded material) through the same integrated equipment, eliminating the need for separate specialized equipment for each material type.
2Loss of substance
If traditional shredding machines are used to process tree waste, then volume reduction can be achieved, but the machines cannot continuously digest large wood sections and soil-saturated materials
Solution Approach 1:
The patent segments the processing into distinct functional zones within a continuous system: initial shearing of large sections, intermediate grinding, and final screening. This segmentation allows each zone to handle specific tasks optimally, with the shearing section breaking down large wood sections into manageable sizes, the grinding section achieving volume reduction, and the screening section separating finished product, enabling continuous processing of all material sizes.
Solution Approach 2:
The system performs preliminary shearing of large wood sections and soil-saturated materials before they enter the main grinding and shredding mechanisms. This preliminary action breaks down oversized and difficult-to-process materials into smaller, more manageable pieces that can be continuously fed into the subsequent processing stages, preventing bottlenecks and maintaining continuous operation.
3Productivity
If manual labor and multiple equipment operators are used for tree waste processing, then processing can be performed, but labor costs and operational complexity increase
Solution Approach 1:
The patent implements a continuous processing system where materials flow continuously through shearing, grinding, and screening operations without interruption. The system maintains continuous operation with automatic material feeding, processing, and discharge mechanisms that eliminate the need for manual intervention between processing cycles, keeping all components in constant productive operation.
Solution Approach 2:
The system incorporates automatic material handling and positioning mechanisms that feed materials through the processing stages without manual assistance. The apparatus self-regulates the flow of materials, with automatic screening and product separation, minimizing the need for operators to manually load, position, or retrieve materials during processing.

AI summary
A system for generating electrical power, including a frame defining a vertical axis and a horizontal axis, and having a support base generally extending along the longitudinal axis. The support base has an input end and an output end. At least a first shear station includes a first shearing blade adapted to reciprocate in a vertical direction between a first displaced position displaced from the support base and a second approximated position proximate the support base to shear the tree waste supported by the support base. An index blade is adapted for at least general horizontal movement along the support base. The index blade is dimensioned and adapted to direct the sheared tree waste toward the output end of the support base. A pulverizing station receives the sheared tree waste directed through the output end of the support base. The pulverizing station includes a pulverizing member actuable to pulverize the sheared tree waste. A furnace receives and converts the pulverized tree waste into steam energy. A steam generator turbine converts the steam energy into electricity.
