Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for suctioning compacted powders and granular materials often result in nozzle damage due to lateral forces and incomplete suction due to low flowability, leading to dead spaces and material scattering.
Innovation Solution
A machine with a double-layered suction nozzle and a movable or stationary table system that allows precise insertion and movement of the nozzle within the container, combined with a controller for optimizing suction patterns and air flow based on container size and material levels, ensuring comprehensive suction and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the nozzle is inserted into compacted powders and granular materials to suction them, then the suctioning capability is improved, but a large lateral force is applied to the nozzle tip causing it to break
Solution Approach 1:
The container is rotated to incline the powders and granular materials before nozzle insertion, creating a slope that guides material flow away from the nozzle tip and reduces lateral forces during suctioning
Solution Approach 2:
The container rotation is dynamically adjusted during the suctioning process to maintain optimal material flow conditions, allowing the system to adapt to changing material levels and flow characteristics
2Ease of operation
If the drum is inclined and rotated to suction powders and granular materials from the bottom, then accessibility is improved, but dead spaces are formed where the nozzle cannot reach
Solution Approach 1:
The container is pre-rotated to gather powders and granular materials at the bottom in a concentrated manner before nozzle insertion, ensuring the nozzle can access all material without creating dead spaces
Solution Approach 2:
The container rotation continues during the suctioning process to maintain material flow toward the nozzle, ensuring continuous and complete suctioning without dead spaces
3Ease of operation
If air is exhaled into the dead space to move powders and granular materials, then material movement is improved, but the powders and granular materials are violently scattered
Solution Approach 1:
The container is pre-rotated to eliminate dead spaces and position all material within the nozzle's suction range, making air exhalation unnecessary and preventing violent scattering
Solution Approach 2:
The harmful action of exhaling air into dead spaces is eliminated by removing the dead spaces themselves through proper container rotation and nozzle positioning
4Strength
If the nozzle is slowly lowered to suction powders and granular materials little by little, then nozzle damage is prevented, but the suctioning time is extended
Solution Approach 1:
The container is pre-rotated to create optimal material flow conditions before nozzle insertion, allowing faster and safer suctioning without compromising nozzle integrity
Solution Approach 2:
The container rotation continues during suctioning to maintain steady material flow, enabling faster and more efficient suctioning while protecting the nozzle from lateral forces

AI summary
The object of the present invention is to suction all powders and granular materials in a container such as a drum to transport them. The powders and granular materials have low flowability, since over time they have been compacted due to their own weight or vibrations from the outside or humidity. The machine (1) for suctioning powders and granular materials comprises movable tables (2, 3) that the container that stores the powders and granular materials is mounted on and that horizontally move, a device (8) for driving the tables, a double-layered suction nozzle (11) that is located above the tables and is connected to a suction source, a device (12) for moving the nozzle up and down in the container mounted on the tables, and a controller for controlling the devices, wherein, while moving the tables, the suction nozzle is inserted in proper positions in the container to suction the powders and granular materials.
