Separating Powder Filter for Automated Powder Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powder dispensing devices require time-consuming and laborious cleaning when switching between different types or kinds of powders, as the powder supply lines need to be accessed through wall openings, making it inefficient to change between powder types.
Innovation Solution
A powder separating filter with multiple inlets and a single outlet allows for selective connection of different powder sources to a powder dispensing device, eliminating the need to clean powder supply lines by enabling automatic powder hose changes without routing lines through wall openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If powder supply lines are routed through wall openings for powder dispensing devices, then the devices can be positioned outside the coating booth, but switching between different powder types requires time-consuming cleaning of the supply lines
Solution Approach 1:
The system is divided into separate segments: multiple powder supply lines are routed through separate wall openings, each dedicated to a specific powder type. This segmentation allows the powder dispensing device to remain positioned outside the coating booth while enabling quick switching between powder types by simply changing which inlet is active, without requiring cleaning of shared supply lines.
2Device complexity
If a single powder supply line is used for multiple powder types, then the system structure is simplified, but extensive cleaning is required when switching between powder types
Solution Approach 1:
The powder dispensing device is designed with multiple inlets that can universally accept different powder types. Each inlet is specifically configured for a particular powder type, allowing the device to function with multiple powders simultaneously without requiring structural changes or extensive cleaning when switching between types.
3Productivity
If powder supply lines are accessed through wall openings, then the dispensing device can operate outside the coating booth, but the cleaning process becomes laborious and time-consuming
Solution Approach 1:
The cleaning requirement is extracted and eliminated by dedicating separate wall openings to each powder type. This allows the powder supply lines to remain in place without cleaning when switching between powder types, as each inlet is specifically configured for its designated powder type, thereby maintaining high operational efficiency while simplifying the switching process.

AI summary
The invention relates to a separating powder filter, particularly for supplying different types and/or sorts of powder, as selected, to a powder delivery device. The separating powder filter comprises the following: a first powder inlet, at least one additional, second powder inlet, and a powder outlet. Either the first powder inlet or the at least one second powder inlet can be fluidically connected to the powder outlet of the separating powder filter.
