Internal Cleaning Nozzle With Gas-Liquid Mixture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing internal cleaning apparatuses struggle to achieve thorough three-dimensional cleaning of internal spaces, particularly in objects like tanks, as they often fail to effectively reach and clean every corner, and may introduce foreign substances that can damage the apparatus or leave behind dirt.
Innovation Solution
An internal cleaning apparatus featuring a rotary shaft with a liquid flow passage and a revolving rotary shaft that combines a liquid flow with a gas flow, forming a gas-liquid mixture, which is ejected through a nozzle that can be oriented and moved to ensure comprehensive cleaning, while a lid seals the opening to prevent external interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a cleaning nozzle is inserted into the internal space to clean surfaces, then cleaning coverage is improved, but foreign substances may infiltrate and damage the apparatus
Solution Approach 1:
The harmful factor (foreign substance) is extracted and separated from the cleaning system by introducing a gas flow that creates a protective barrier and directs contaminants away from the apparatus, allowing the nozzle to maintain insertion for cleaning coverage while preventing contamination
Solution Approach 2:
A gas flow is introduced as an intermediary substance between the external environment and the cleaning apparatus. This gas flow acts as a protective mediator that prevents foreign substances from directly contacting the apparatus while still allowing the liquid cleaning flow to effectively clean the internal space
2Reliability
If a liquid flow is used for cleaning, then cleaning action is maintained, but cleaning reach into corners is insufficient
Solution Approach 1:
The liquid flow cleaning system is merged with a gas flow system to create a combined gas-liquid mixture flow. This combination allows the cleaning action to maintain consistency through the liquid while the gas component extends the reach into corners and hard-to-access areas, solving both reliability and cleaning reach requirements simultaneously
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 configuration enables efficient, three-dimensional cleaning of internal spaces with a wide spraying range, preventing damage from foreign substances and ensuring a stable, reliable cleaning action by using a gas-liquid mixture and a smooth, flattened nozzle for enhanced coverage.
Implementation Method 1
a gas flow passage being provided along the liquid flow passage of each of the rotary shaft and the revolving rotary shaft from a gas inflow opening provided in the rotary shaft, wherein a gas-liquid mixture flow having a gas supplied from outside an object to be cleaned mixed with the liquid is ejected from the nozzle
