Conical Diffuser Plate for FRP Pressure Vessel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing FRP pressure vessels lack efficient internal features and accessories, particularly diffuser plates, which restrict access and functionality, leading to limited installation of features and increased manufacturing costs and complexity.
Innovation Solution
The integration of conical internal diffuser plates within FRP tanks, allowing for customizable installation by cutting the plastic liner and creating weld grooves for secure attachment, reducing tooling expenses and enhancing manufacturing flexibility, while the conical shape reduces stress and maximizes tank volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a filter basket is used in existing FRP pressure vessels, then the tank can perform water treatment, but the access to the tank is restricted and installation of internal features is limited
Solution Approach 1:
The diffuser plate is divided into multiple segments or sections that can be independently installed and accessed. The plate includes multiple openings that can be selectively configured, allowing different internal features to be installed in different sections without requiring complete disassembly of the tank.
Solution Approach 2:
The diffuser plate serves as an intermediary component between the tank interior and the internal features. It provides a standardized interface with multiple openings that can accommodate various accessories, enabling easy installation and removal of internal features without direct access to the tank interior.
2Ease of manufacture
If traditional diffuser plates are installed in FRP tanks, then fluid dispersion is achieved, but manufacturing costs and complexity increase
Solution Approach 1:
The diffuser plate utilizes variations in opening size, shape, and distribution as adjustable parameters to achieve different fluid dispersion patterns. By changing these parameters, the same basic plate design can serve multiple applications, reducing the need for custom-manufactured components and lowering manufacturing costs.
Solution Approach 2:
The diffuser plate is designed with multiple openings of varying configurations that can serve different functions within a single component. This multi-functionality eliminates the need for separate components for different fluid distribution requirements, simplifying the manufacturing process and reducing overall device complexity.
3Ease of operation
If the plastic liner is cut to install diffuser plates, then access to the tank interior is enabled, but the liner integrity is compromised
Solution Approach 1:
The diffuser plate is designed with pre-formed openings and attachment features that allow installation before the tank is fully assembled or before the liner is permanently sealed. This preliminary action enables access to be created at the optimal time without compromising the overall integrity of the liner system.
Solution Approach 2:
The diffuser plate creates a replicated access pathway through its multiple openings, providing alternative routes for installation and maintenance access. If one opening or access point is compromised, the other openings serve as backups, maintaining the overall reliability of the tank system.
