Apparatus for separating extraneous particles of a fluid in a hydraulic circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic circuit apparatuses for separating extraneous particles, such as dirt separators and deaerators, face installation challenges due to their large size and configuration, making them unsuitable for systems with limited space, and they often result in high pressure drops and frequent cleaning requirements.
Innovation Solution
A compact apparatus with a tubular configuration and deflecting flaps within the conduit creates turbulent fluid motion to separate and collect particles, allowing for efficient removal of both solid and gaseous impurities with minimal pressure drops and easy installation in constrained spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional dirt separators and deaerators are used, then effective particle separation is achieved, but the apparatus size becomes large and installation space is insufficient
Solution Approach 1:
The patent integrates both the dirt separator function and deaerator function into a single unified apparatus. The collecting chamber serves dual purposes: collecting solid particles that settle at the bottom and capturing gaseous bubbles that rise to the top. This nesting of multiple separation functions within one apparatus structure reduces the overall volume compared to using separate dirt separator and deaerator units.
Solution Approach 2:
The apparatus is designed to perform multiple functions simultaneously: separating solid particles from fluid and removing gaseous bubbles from the fluid. The single collecting chamber handles both types of impurities, making the apparatus universal in its separation capabilities and eliminating the need for multiple specialized devices.
2Quantity of substance
If traditional large chamber apparatuses are used, then particle collection capacity is sufficient, but cleaning frequency increases and maintenance becomes frequent
Solution Approach 1:
The patent incorporates an automatic purging mechanism that uses the hydraulic circuit's own fluid flow to periodically clear the collecting chamber. The purging conduit allows fluid under pressure to flush accumulated particles and bubbles out of the chamber, enabling the apparatus to self-clean without manual intervention. This reduces cleaning frequency and maintenance requirements while maintaining adequate collection capacity.
3Volume of moving object
If compact tubular configuration is used, then installation space is reduced, but pressure drop may increase
Solution Approach 1:
The apparatus is designed as a tubular structure with segmented functional zones: an inlet section, a collecting chamber section with deflecting flaps, and an outlet section. The deflecting flaps are arranged to create localized turbulence only where needed for particle-bubble collision, rather than throughout the entire flow path. This segmented approach minimizes overall pressure drop while achieving effective separation in a compact volume.
