Funnel with Suction Means for Dust-Free Powder Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for dosed dispensing of powdered substances from a magazine often result in dust clouds, leading to inefficiencies and potential contamination when handling different powdery substances.
Innovation Solution
The method involves using a funnel with integrated suction means to extract dust clouds and a metering valve for controlled dispensing, along with blowing nozzles for cleaning, ensuring efficient extraction and prevention of contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the container is tipped into a funnel for dosed dispensing, then the dispensing process can be achieved with relatively simple means, but dust clouds are released from the container causing contamination
Solution Approach 1:
The harmful dust cloud is extracted from the system by connecting suction means directly to the funnel. The suction means removes dust clouds released from the container during the tipping and dispensing process, preventing contamination while maintaining the simple dispensing mechanism.
Solution Approach 2:
The funnel acts as an intermediary element between the container and the dispensing point. By coupling the suction means to the funnel, the system captures dust at the source without requiring complex sealed container mechanisms, thus maintaining simplicity while preventing dust release.
2Productivity
If the funnel is used for dispensing without cleaning, then the process is simple, but contamination occurs when handling different powdery substances
Solution Approach 1:
The funnel performs self-cleaning by using the remaining powdery substance to blow out dust clouds through the suction means. This automatic cleaning process ensures purity when handling different substances without requiring manual intervention or complex cleaning mechanisms.
Solution Approach 2:
The system uses the remaining powdery substance in the funnel for a secondary purpose - blowing dust clouds out through the suction means. This converts what would be waste material into a useful cleaning agent, ensuring purity while maintaining productivity.
3Loss of time
If the container is removed from the funnel without extraction, then the process is faster, but dust clouds escape causing contamination
Solution Approach 1:
The suction means operates continuously during the container removal process, maintaining extraction of dust clouds throughout the entire operation. This continuous action ensures no dust escapes while the container is being removed, balancing speed with contamination prevention.
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
This approach effectively minimizes dust clouds and contamination, allowing for efficient and clean handling of powdery substances by ensuring complete extraction and cleaning of the dispensing system.
Implementation Method 1
dust clouds released from the container are extracted by suction means arranged on the funnel mouth
Implementation Method 2
the funnel is blown clean by nozzles and the powdery substance blown away is extracted by the suction means

AI summary
In a method for dosed dispensing of powdery substance from a magazine in which containers with different powdery substances are contained therein, first the container 3 with the desired powdery substance is removed from the magazine and then a funnel 11 is placed upside down on a container 3 that is open at the top. Subsequently, the container 3 and the funnel 11 thereon are turned upside down so that the contents of the container end up in the funnel. The funnel mouth 17 is then opened for dosed dispensing of the powdery substance 4 until the desired amount has dropped from the funnel 11, after which the funnel mouth 17 is closed. Subsequently, the container 3 and the funnel 11 present underneath are turned back so that the remaining powdery substance 4 falls back into the container. Finally, the funnel 11 is removed from the container 3 and the container is placed back in the magazine.
