Rotating Scraper Screen for Bottle Processing Machine Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bottle treatment machines face clogging issues due to foreign matter like label residues and glue in process water, which obstructs pump and nozzle screens, requiring frequent manual cleaning and increasing workload.
Innovation Solution
A bottle treatment machine with a screen having a partially perforated surface and a rotatable scraper for mechanical cleaning, allowing foreign matter to be screened out and removed during operation, maintaining liquid throughput without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cleaning of screens is used, then foreign matter can be removed, but workload and personnel deployment increase
Solution Approach 1:
The screen cleaning system performs self-service by automatically removing foreign matter from the screen surface. The scraper mechanism is driven by the screen's own rotation, eliminating the need for external manual intervention. The system cleans itself continuously during operation, transforming from a manual task requiring personnel deployment to an autonomous self-maintaining function.
Solution Approach 2:
The patent replaces the manual mechanical cleaning system with an automated mechanical scraping system. Instead of manual labor, a scraper element mechanically removes foreign matter from the screen surface through rotational motion. This substitution transforms human-operated mechanical cleaning into automated mechanical cleaning, reducing workload while maintaining cleaning effectiveness.
2Reliability
If screens are used to separate particles, then foreign matter can be removed from process water, but screens become clogged and require frequent cleaning
Solution Approach 1:
The patent ensures continuity of useful action by implementing continuous screen cleaning during the separation process. The scraper operates simultaneously with the screen's rotation and the water flow, continuously removing foreign matter as it accumulates. This prevents interruptions in the separation process and maintains constant screen throughput, eliminating the need to stop operation for cleaning.
Solution Approach 2:
The scraper performs preliminary action by removing foreign matter before it can completely clog the screen pores. By continuously scraping the screen surface, the system prevents the accumulation of sufficient foreign matter to block flow, thereby maintaining screen permeability and throughput throughout the operation cycle.
3Ease of manufacture
If plug-in screens are used, then cleaning can be performed, but system complexity and personnel deployment increase
Solution Approach 1:
The patent merges the screen filtration function with the cleaning function into a single integrated system. The scraper mechanism is combined with the screen assembly, creating a unified unit where cleaning and filtration occur simultaneously. This integration eliminates the need for separate manual cleaning operations or complex plug-in mechanisms, reducing overall system complexity while maintaining ease of manufacture.
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 effectively removes 80-95% of foreign matter from the screen, preventing clogging and ensuring continuous operation of the bottle treatment machine until the next cleaning phase, reducing manual workload and maintaining system efficiency.
Implementation Method 1
at least one scraper (17, 26), which rests at least partially on the at least partially perforated surface of the screen (15)
