Poker Compactor Pivoting Motion for Bulk Material Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compacting devices that enter open packages from above and use vacuum suction to compact bulk materials often leave a significant amount of material adhering to the outer surface, leading to contamination and cleanliness issues due to their external operation.
Innovation Solution
A compacting device with a poker compactor that pivots around its central longitudinal axis, allowing it to loosen and wipe off adhering bulk material particles during removal, reducing contamination and improving cleanliness by using a gas-permeable outer wall connected to a suction duct for efficient degassing and compacting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a poker compactor enters an open package from above and uses vacuum suction to compact bulk material, then compacting efficiency is improved, but bulk material adheres to the outer surface of the compacting unit causing contamination
Solution Approach 1:
The poker compactor is designed to perform a pivoting motion around its longitudinal axis during insertion and removal from the package. This dynamic movement creates shear forces that prevent bulk material from adhering to the outer surface of the gas-permeable wall, thereby reducing contamination while maintaining compacting efficiency through vacuum suction
Solution Approach 2:
The pivoting motion of the poker compactor around its longitudinal axis generates mechanical shear forces that effectively loosen and remove bulk material particles from the outer surface during insertion and removal operations, preventing adhesion and contamination
2Object-generated harmful factors
If a bottom vibrator applies vibrations from beneath to compact bulk material, then compacting is achieved without adhesion issues, but the device cannot effectively degas the bulk material
Solution Approach 1:
The invention combines two previously separate functions into a single poker compactor: the gas-permeable wall provides vacuum suction capability for effective degassing, while the pivoting motion around the longitudinal axis provides the mechanical action needed to prevent bulk material adhesion, merging the advantages of both approaches
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
The pivoting motion effectively reduces the amount of bulk material transported outward, decreases contamination, and enhances cleanliness by ensuring that less material adheres to the compacting device, allowing for more efficient and accurate filling and compacting processes.
Implementation Method 1
The poker compactor comprises an outer wall that is at least partially gas-permeable and connected with a suction duct... sucks air out of the bulk material contained therein
Implementation Method 2
the poker compactor to pivot around its longitudinal axis following compacting, so that any bulk material particles adhering to or caking on the outer surface or the outer wall of the poker compactor are loosened or wiped off (due to inherent friction in the bulk material)
