Rotating Tank Cleaning Nozzle for Full Interior Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cleaning larger tanks, such as oil tanks, is a challenging and potentially hazardous task due to the need to access all internal surfaces, requiring an efficient and reliable method to remove solids and fluids like sludge.
Innovation Solution
A nozzle arrangement with a rotating mechanism, comprising a primary drive shaft, gear teeth, an angular gear, and a worm gear, which rotates the nozzle pipe section to efficiently inject and distribute cleaning liquid across the tank's interior, including an angled cleaner head and secondary drive shaft for targeted cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning methods are used for tank interiors, then personnel can directly access and clean surfaces, but health risks increase and cleaning efficiency decreases
Solution Approach 1:
The patent introduces a nozzle arrangement as an intermediary device that delivers cleaning liquid into the tank without requiring personnel to enter or directly contact the contaminated interior surfaces. The system uses a rotating mechanism with multiple nozzles that can be positioned to clean all internal surfaces including bottom and side surfaces, thereby maintaining cleaning effectiveness while eliminating health risks associated with manual cleaning.
2Area of stationary object
If cleaning liquid is injected statically into the tank, then the injection mechanism is simple, but coverage of internal surfaces is insufficient
Solution Approach 1:
The patent employs a rotating mechanism that dynamically positions multiple nozzles to cover the entire internal surface area of the tank. The rotation mechanism, driven by gears including a worm gear for precise control, allows the nozzle assembly to sweep across bottom and side surfaces, transforming a static injection system into a dynamic one that achieves comprehensive coverage while maintaining reasonable mechanical complexity.
3Reliability
If regular interval cleaning is performed, then tanks are maintained properly, but health risks and operational disruptions are enforced repeatedly
Solution Approach 1:
The rotating nozzle arrangement enables continuous and thorough cleaning action that can be completed efficiently in a single operation during each maintenance interval. The system rotates to clean all surfaces systematically, ensuring reliable cleaning results while minimizing the time the tank is out of service, thus reducing operational disruptions associated with regular cleaning cycles.
