Ionizing Electrode with Solenoid-Driven Linear Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ionizing electrode cleaning devices suffer from low cleaning efficiency and complexity due to the need for nonlinear motion of wire electrodes within bushings, which limits the cleaning area and increases complexity.
Innovation Solution
An ionizing electrode formed as a thin wire from conducting spring material is mounted inside a bushing with a solenoid-driven linear back-and-forth movement mechanism, utilizing a high voltage supply and return spring to ensure the electrode's ionizing end is fully cleaned by matching the electrode's cross-section with the bushing's inner diameter and using short voltage pulses for efficient dust removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inner diameter of the bushing is made much larger than the wire diameter to facilitate wire sliding during nonlinear back-and-forth motion, then the wire can move freely inside the bushing, but only a part of the wire circumference is cleaned, resulting in low cleaning efficiency
Solution Approach 1:
The invention changes the motion parameter from nonlinear back-and-forth motion to linear reciprocating motion. The wire electrode moves linearly along its axis inside the bushing, entering and exiting through the bushing ends. This linear motion allows the entire wire circumference to be cleaned while maintaining smooth sliding through the bushing.
2Length of moving object
If the length of the bushing is made many times smaller than the maximum amplitude of back-and-forth motion of the wire, then the wire can travel sufficient distance for cleaning, but the bushing cannot contain the wire effectively, resulting in poor cleaning quality
Solution Approach 1:
Instead of having the wire move back-and-forth within the bushing length, the invention inverts the approach by having the wire travel linearly beyond the bushing ends. The bushing length is now shorter than the wire travel distance, with the wire entering and exiting the bushing during its linear reciprocating motion, ensuring complete circumference cleaning.
3Extent of automation
If complex devices are used to convert linear movement to rotational movement or rotational movement to linear movement for cleaning, then the cleaning mechanism can be actuated, but the device complexity increases
Solution Approach 1:
The invention extracts and eliminates the complex motion conversion mechanisms from the system. Instead of using devices to convert linear movement to rotational movement or vice versa, the system directly uses linear reciprocating motion of the wire electrode, simplifying the overall device structure while maintaining automated cleaning functionality.
4Use of energy by moving object
If centrifugal force is used as the energy source for the cleaning process, then the cleaning mechanism can operate, but the cleaning effectiveness is insufficient for thorough dust removal
Solution Approach 1:
The invention replaces centrifugal force with mechanical vibration as the energy source for cleaning. The wire electrode is subjected to high-frequency vibrations during its linear reciprocating motion through the bushing, which significantly enhances dust removal effectiveness compared to centrifugal force alone.
