Air Drier Cartridge With Collision Member For Oil Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air drier cartridges for commercial vehicles are inadequate in effectively removing oil and water from compressed air, leading to reduced system durability and increased manufacturing costs due to the need for additional components like check valves, which compromise sealing and increase costs.
Innovation Solution
An air drier cartridge design featuring a collision member in the gap between the cartridge body and housing to pre-filter oil, followed by an oil adsorption filter, eliminating the need for a check valve and enhancing the sealing ability with a '⊏' shape gasket, thereby improving the filtration efficiency and lifespan of the oil adsorption filter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a check valve is installed adjacent to the adsorption filter to enable compressed air to bypass the oil adsorption filter during regeneration, then the regeneration process can be achieved, but the manufacturing cost increases and complete sealing cannot be achieved around the check valve
Solution Approach 1:
The patent removes the check valve from the system entirely. Instead of using a check valve to control airflow direction during regeneration, the invention uses the structural design of the housing and cartridge body with integrated flow paths that naturally guide compressed air to bypass the oil adsorption filter during regeneration without requiring any additional valving components.
Solution Approach 2:
The housing structure serves multiple functions: it provides structural support, defines flow paths for both normal operation and regeneration modes, and eliminates the need for separate sealing components around check valves. The integrated design makes the housing universal for both filtration and regeneration functions.
2Object-affected harmful factors
If only an oil adsorption filter is used to remove oil from compressed air, then the structure is simple, but the oil removal performance is insufficient
Solution Approach 1:
The collision member is positioned upstream of the oil adsorption filter to perform preliminary oil removal by causing compressed air to collide with the collision member surface, separating larger oil droplets before the air enters the oil adsorption filter. This preliminary action reduces the oil load on the adsorption filter and enhances overall oil removal performance.
Solution Approach 2:
The collision member acts as an intermediary component between the compressed air inlet and the oil adsorption filter. It mediates the oil removal process by providing a surface for oil droplet separation and collision, bridging the gap between raw compressed air and the adsorption filter to improve overall filtration efficiency.
3Duration of action of moving object
If the oil adsorption filter is exposed to all compressed air containing oil, then oil removal is maximized, but the lifespan of the oil adsorption filter is reduced
Solution Approach 1:
The collision member performs preliminary oil separation before compressed air enters the oil adsorption filter, removing a significant portion of oil content in advance. This preliminary action extends the lifespan of the oil adsorption filter by reducing the total oil load it must handle, while maintaining effective oil removal performance through the combined action of both components.
Solution Approach 2:
The collision member handles the excessive oil removal task partially, taking on the burden of removing large oil droplets and reducing the workload on the oil adsorption filter. This partial action by the collision member protects the filter from premature saturation and extends its service life.

AI summary
The present disclosure relates to a drier cartridge that can improve the effect of cleaning compressed air by filtering out water, oil, and foreign substances, which are contained in compressed air, through several steps therein. In particular, when a narrow compressed air channel is formed between a cartridge body and a cartridge housing, a collision member that is a pre-filtering member that can primarily filter out oil, etc. is formed between the cartridge body and the housing, whereby it is possible to improve the performance of removing oil and water from a filter cartridge.
