Disposable Liner for Drum Lifter Inverter Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixing technologies face challenges in minimizing ingredient loss and ensuring consistent proportions during the mixing of large batches, particularly due to trapping of materials within containers during the pouring process, which is influenced by viscosity and ambient conditions.
Innovation Solution
A drum lifter/inverter machine with a cone-shaped funnel and a disposable liner that facilitates complete removal of materials by allowing the drum to be inverted and secured to the liner, ensuring accurate and reproducible blending through controlled flow and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If traditional pouring methods are used to transfer ingredients from containers to mixing equipment, then the process is simple and quick, but significant ingredient loss occurs due to material trapping in containers
Solution Approach 1:
A disposable liner is introduced as an intermediary component between the drum and the mixing equipment. The liner facilitates complete discharge of ingredients by providing a smooth surface that prevents material adherence, acting as a mediator that enables near-100% transfer efficiency while maintaining simple operation
Solution Approach 2:
The patent employs disposable liners that are discarded after single use. These inexpensive, single-use components eliminate the need for complex cleaning procedures and ensure consistent performance without material buildup, resolving the contradiction between minimizing loss and maintaining productivity
2Manufacturing precision
If traditional mixing equipment without liners is used, then the device structure is simple, but ingredient proportions are inconsistent due to variable trapping losses
Solution Approach 1:
The disposable liner provides a consistent, controlled surface for ingredient flow without requiring complex mechanical or thermal systems. This simple yet effective approach ensures reproducible ingredient discharge and proportional accuracy while avoiding the complexity of active cleaning or heating mechanisms
Solution Approach 2:
The liner function is extracted as a separate, removable component rather than being integrated into the permanent equipment structure. This allows the core mixing equipment to remain simple while the liner provides the necessary controlled-discharge functionality
3Loss of time
If permanent mixing equipment is used without disposable components, then equipment cost is lower initially, but cleaning time and maintenance requirements increase operational costs
Solution Approach 1:
The disposable liner eliminates cleaning operations entirely by being discarded after single use. This resolves the time loss associated with cleaning while the low cost of the liner itself offsets the manufacturing cost increase, achieving both time and cost efficiency
Solution Approach 2:
Instead of cleaning and reusing expensive equipment surfaces, the system discards the liner after use. This approach recovers the time value by eliminating cleaning cycles while the inexpensive nature of the liner makes the discarding strategy economically viable
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 significantly reduces waste and improves the consistency and accuracy of ingredient proportions by ensuring complete discharge and easy cleaning, addressing the issues of loss and variability in mixing processes.
Implementation Method 1
After elevating and inverting the drum using the stanchion and arm, a flow control valve may be actuated to permit flow of the material from the drum and through the liner/cone, and into the mixing container

AI summary
A disposable liner, used with a cone-shaped funnel of a drum lifter/inverter mixing/discharge machine, may include a first liner portion formed into a hollow cylinder having a first diameter and a first thickness. The first liner portion transitions into a second portion that is formed into a conical shape, with a first end formed to the first diameter, and with a second end formed to a second diameter being larger than the first diameter. The second portion is formed with a plurality of openings positioned a small distance away from the second end and are spaced equally spaced about a third diameter of the second portion. Each the openings are formed to a special elliptical shape, with a corresponding elliptically formed grommet, to be configured to be preloaded with respect to the center of corresponding buttons on the cone, onto which the openings may be received to mount the liner.
