Removal Station Pressing Device for Container Base Leveling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing removal stations for fluid materials from storage containers often leave residual volumes due to the container bottom bulging, which cannot be completely emptied by conventional methods, leading to significant and undesirable material loss, especially in heavy containers used for plastic formulations.
Innovation Solution
A height-adjustable pressing device is integrated into the removal station, applying vertically upward forces to the container base, leveling it and preventing bulging, allowing for complete removal of residual material by a suction conveyor system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the container bottom is allowed to bulge under the weight of filling material, then the container structure remains simple and stable, but residual material remains in the container that cannot be conveyed out
Solution Approach 1:
The container bottom is pre-tensioned during manufacturing to create an upward bulge that counteracts the downward sagging caused by material weight. This preliminary structural action prevents the container bottom from bulging downward during operation, eliminating dead zones where residual material would otherwise accumulate and ensuring complete material conveyance.
2Productivity
If a conventional follower plate is used to convey material, then the device structure remains simple, but residual material in the container cannot be completely removed
Solution Approach 1:
The container bottom is pre-formed with an upward bulge that maintains a consistent slope toward the discharge opening. This preliminary geometric configuration ensures that material flows continuously toward the outlet without creating stagnant zones, allowing the follower plate to completely evacuate all material including what would otherwise remain as residue.
3Quantity of substance
If the container bottom sags under material weight, then the container can hold more material, but the residual volume that cannot be conveyed increases
Solution Approach 1:
The container bottom is pre-tensioned to create an upward bulge that counteracts gravitational sagging. This preliminary structural action maintains the container bottom in a state that promotes complete material flow, ensuring that the maximum quantity of material can be conveyed while minimizing or eliminating residual losses.
Solution Approach 2:
The upward bulge in the container bottom creates a pre-opposing force against the downward sagging tendency caused by material weight. This preliminary anti-action prevents the formation of dead zones and ensures continuous material flow toward the discharge opening, eliminating residual material accumulation.
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 solution ensures that the container bottom is aligned horizontally, enabling the complete removal of residual fluid material, minimizing material loss and reducing operational costs by preventing manual handling of residues.
Implementation Method 1
a height-adjustable pressing device (20) is provided in the removal area (5), which comprises a pressure member (22) that can be placed against the underside of the container base (2a) when the container (2) is in its removal position, and a pressing element (23) that can be transferred into a pressing position on the container (2) and presses the container base (2a) relative to the container wall (2b), i.e. applies vertically upward forces on the container base
Implementation Method 2
a conveying device (10) for removing the fluid material from the storage container, with the conveying device having an inlet area for the fluid medium designed as a suction element
