Spray Gun Cup Cleaning Apparatus with Segmented Drain Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for spray gun components fail to completely separate and reuse cleaning agents contaminated with substances, leading to inefficient use and excessive consumption of cleaning agents.
Innovation Solution
A device with a pneumatic discharge allocation system, including a slide valve, allows for the separation and reuse of cleaning agent fractions by directing them to different collection containers, enabling efficient recycling and reapplication of less heavily contaminated cleaning agents through a rotating carousel design and stainless steel filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If cleaning agents are used in successive cleaning steps without separation, then cleaning process is simple, but cleaning agent consumption increases and reuse becomes impossible
Solution Approach 1:
The cleaning device is segmented into multiple independent cleaning steps (pre-cleaning, main cleaning, rinsing) with separate collection containers for each step. This allows cleaning agents from different steps to be collected and reused independently, reducing overall consumption while maintaining manageable device complexity through modular design
Solution Approach 2:
The system recovers cleaning agents from each cleaning step by collecting them in separate containers. The pre-cleaning agent is collected and can be reused in subsequent pre-cleaning steps, the rinsing water is collected and can be reused for rinsing, thereby recovering valuable substances and reducing consumption
2Loss of substance
If cleaning agents from different cleaning steps are mixed, then collection process is simple, but reuse of less contaminated agents becomes impossible
Solution Approach 1:
The collection system is segmented into separate collection containers for different cleaning steps (pre-cleaning container, rinsing water container). This segmentation prevents mixing of cleaning agents with different contamination levels, enabling selective reuse of less contaminated agents while keeping the collection system structure relatively simple
Solution Approach 2:
The system extracts and separates the cleaning agents from different cleaning steps into distinct containers. By taking out the pre-cleaning agent and rinsing water separately, the system enables targeted reuse of each fraction according to its contamination level, improving reuse potential without excessive complexity
3Loss of substance
If all cleaning liquid is directed to a single drain, then device operation is simple, but cleaning agent waste increases
Solution Approach 1:
The discharge system is segmented with separate outlets for different cleaning steps (pre-cleaning discharge, rinsing water discharge). This allows selective control of where each cleaning agent fraction is directed, reducing waste by enabling reuse while maintaining ease of operation through automatic or simple manual valve control
Solution Approach 2:
The discharge allocation device uses movable components (such as slide valves or rotary distributors) that can dynamically redirect cleaning agents to different collection containers or drains based on the cleaning step. This dynamic control enables waste reduction without significantly complicating operation

AI summary
The invention discloses an apparatus for cleaning cup-like containers of spray guns, spray guns and parts thereof, wherein said apparatus is configured in such a way that, as same passes through cleaning, cleaning liquids contaminated differently with substances to be removed are at least partly allocated to different collecting containers (2, 2') as drains by means of at least one drain allocation device (1).
