Unmanned Tank Lining Installation via Intermediate Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing tank inner linings require fitters to enter the tank, posing risks due to potential explosive gases and making the process hazardous, and existing solutions do not provide a safe and efficient way to rehabilitate tanks without replacing them.
Innovation Solution
A method for unmanned installation of a tank inner lining using a tank inner lining with an inner shell and intermediate layer, supported by an installation aid, which allows the lining to be inserted and aligned without entering the tank, utilizing a pulling device and guide element to position and expand the lining within the tank.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fitter enters the tank to install the inner lining, then the installation can be performed manually with direct control, but the safety risk increases due to potential explosive gases and hazardous environment
Solution Approach 1:
The patent introduces an installation aid as an intermediary device that operates inside the tank without requiring a fitter to enter. The installation aid includes a support structure with fastening elements that can be controlled from outside the tank, serving as a mediator between the operator and the hazardous environment while performing the installation tasks
Solution Approach 2:
The patent replaces the mechanical system of manual entry and hand-operated installation with a remotely controlled or automated installation aid. The fastening elements can be actuated by pneumatic, hydraulic, or electric actuators that are controlled from outside the tank, substituting direct mechanical manipulation with remote or automated systems
2Reliability
If the tank is excavated to replace the tank, then the tank can be completely replaced, but the operational disruption and economic cost increase significantly
Solution Approach 1:
The patent applies preliminary action by installing the protective lining inside the existing tank while the tank remains in place and operational. This allows the tank to be rehabilitated and protected against leaks before any potential failure occurs, avoiding the need for excavation and complete tank replacement
Solution Approach 2:
The patent implements the nesting principle by placing an inner lining inside the existing tank structure. The inner lining is nested within the tank, creating a protective barrier without requiring removal of the outer tank structure, thus avoiding excavation and operational disruption
3Productivity
If the inner lining is inserted and inflated to line the tank, then the lining can be installed efficiently, but positioning and alignment become difficult without manual entry
Solution Approach 1:
The installation aid serves as an intermediary that provides support and positioning functions inside the tank. It includes fastening elements that can attach to the inner lining and control its position and alignment during installation, enabling precise placement without manual entry
Solution Approach 2:
The patent incorporates feedback mechanisms through sensors and detection devices that monitor the position and alignment of the inner lining during installation. This feedback is transmitted to operators outside the tank, allowing real-time adjustments to achieve proper positioning and alignment
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
This method eliminates the need for fitters to enter the tank, reducing risk and enabling safe rehabilitation of tanks by allowing the lining to be installed efficiently without manual entry, thus preventing hazardous situations and facilitating compliance with safety regulations.
Implementation Method 1
The tank inner lining can be deployed, for example, by filling the inner shell with a fluid. The inner shell can be filled with air or another gas, for example.
Implementation Method 2
In the lined state, the intermediate layer is arranged between the inner shell and the tank wall and the intermediate layer bears against the tank wall at least in sections.

AI summary
The method involves lining the inner region (2) of the tank (1), by inserting the tank inner lining (15) inserted into the inner region of tank through tank opening (7), and unfolding the tank inner lining in the inner region of tank. An intermediate layer between the inner casing and the tank wall (3) is arranged in the cased condition. The intermediate layer is applied in sections against the tank wall. The tank inner lining is positioned in the lining, with the support of auxiliary mounting device in a non-deployed or expanded state and/or is aligned partially. An independent claim is included for tank inner lining.
