Roll Cage Waste Compaction Chamber for High-Pressure Bale Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste compacting technologies, such as roll cages, are limited by their weight capacity and risk damage from excessive pressure, preventing high compaction and requiring manual handling, while existing compactors produce bales with low height-to-width ratios and necessitate manual handling.
Innovation Solution
A waste compacting apparatus with an outer framework, inner compaction chamber, compaction plate assembly, and ejection assembly, utilizing hydraulic rams and scissor mechanisms to compact waste within a roll cage, allowing for high compaction forces and automated ejection without manual handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a roll cage framework is used for waste compaction, then the apparatus is portable and easy to operate, but the framework is relatively light weight and at risk of damage from large pressure, preventing high compaction
Solution Approach 1:
The framework is divided into two distinct parts: an outer framework that provides portability and an inner compaction chamber that provides structural strength. The inner chamber is fixedly attached to the outer framework, creating a composite structure where each component serves its optimal function.
Solution Approach 2:
Different parts of the framework have different properties: the outer framework is designed for portability while the inner compaction chamber is designed for strength and rigidity to withstand high compaction pressures. This local differentiation allows the light-weight roll cage to achieve high compaction capability.
2Ease of operation
If a tilting bale ejector is used, then the bale can be ejected from the compacter, but the bale has low height relative to width and requires manual handling
Solution Approach 1:
Instead of tilting the ejector to eject the bale sideways or downward, the pusher plate moves horizontally in the same direction as the roll cage insertion, pushing the bale forward along the insertion path. This inverted ejection direction allows the bale to be ejected in a controlled manner that facilitates automated handling.
Solution Approach 2:
The ejection mechanism is integrated with the roll cage insertion mechanism, using the same horizontal movement path. The pusher plate automatically ejects the bale when the roll cage is inserted, eliminating the need for separate manual handling operations.
3Stability of the object's composition
If side plates are used to stabilize the roll cage during compaction, then the roll cage is supported, but the side plates add device complexity and the roll cage framework remains light weight
Solution Approach 1:
The support structure is merged with the compaction chamber itself. The inner compaction chamber's side walls serve dual purposes: they form the compaction space and simultaneously provide structural support and stabilization for the roll cage during compaction, eliminating the need for separate support plates.
Solution Approach 2:
The inner compaction chamber performs multiple functions: it contains the waste for compaction, provides structural strength to withstand compaction pressures, and stabilizes the roll cage during the process. This multi-functionality reduces overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables high compaction of waste within roll cages, reducing storage space and transport costs by achieving compaction equivalent to multiple roll cages with a single compaction, and facilitating automated waste ejection into roll cages.
Implementation Method 1
waste is compacted by a pressure plate referred to as a, 'platen' which is pressed downward by a hydraulic ram onto the waste in the roll cage
Implementation Method 2
A pair of side plates then move inwardly to stabilise and support the sides of the roll cage during compaction of waste. Waste is then compacted by a pressure plate referred to as a, 'platen' which is pressed downward by a hydraulic ram onto the waste in the roll cage
Implementation Method 3
A pusher plate is then employed to urge the roll cage out of the apparatus

AI summary
A waste compacting apparatus (10) comprises an outer framework (1); an inner compacting chamber (7); a compaction plate assembly; and a waste ejection assembly for ejecting compacted waste from the apparatus. The inner compacting chamber comprises a pair of spaced apart side walls (8, 8') and a base (9), wherein the side walls and base are fixedly attached to the outer framework. The inner compacting chamber is positioned within the outer framework such that the side walls and the base of the inner compacting chamber locate within an interior space of a roll cage when a roll cage is introduced into the framework. The compaction plate assembly includes a press plate (14) which is moveable between an upper position and a lower position within the inner compacting chamber such that waste within the inner compacting chamber is compacted by the press plate. The waste ejection assembly comprises at least one pusher plate (15) configured to move between a retracted position located at a rear region of the inner compaction chamber, and an extended position located at a front region of the inner compaction chamber. A method for compacting waste using the apparatus is also disclosed.
