Rotating Nozzle Flushing Device for Self-Cleaning Flush Liquid Pipe
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flushing devices cannot effectively clean the flush liquid pipe within enclosed spaces, such as marine tanks, limiting their overall cleaning efficiency and requiring additional complexity or components.
Innovation Solution
The flushing device is equipped with a rotatable nozzle device that directs flush liquid streams to contact the flush liquid pipe during rotation, allowing for the pipe's periphery to be cleaned efficiently, with adjustable nozzle orientations and spreads to ensure thorough cleaning without increasing component complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the flushing device uses a simple nozzle arrangement for cleaning enclosed spaces, then the device complexity is low and cost-effective, but the flush liquid pipe cannot be cleaned effectively
Solution Approach 1:
The nozzle device is designed to perform multiple functions: cleaning the enclosed space and cleaning the flush liquid pipe. By orienting nozzles to direct flush liquid streams against both the tank interior and the pipe periphery during rotation, a single device structure achieves dual cleaning purposes without requiring separate systems
Solution Approach 2:
The rotatable nozzle device dynamically adjusts the direction of flush liquid streams during operation. As the nozzle device rotates about the longitudinal axis and the nozzles rotate about their own axes, the spray pattern dynamically contacts different portions of the pipe periphery and tank interior, enabling comprehensive cleaning without additional components
2Reliability
If additional components are added to clean the flush liquid pipe, then the cleaning effectiveness improves, but the device complexity and cost increase
Solution Approach 1:
The existing nozzle device is made multi-functional to clean both the enclosed space and the flush liquid pipe. The same nozzles that spray the tank interior are oriented to also contact the pipe exterior during rotation, eliminating the need for separate cleaning components
Solution Approach 2:
The flush liquid pipe cleans itself through the rotating nozzle device. The high-velocity flush liquid streams directed at the pipe periphery during rotation automatically remove contaminants from the pipe exterior without requiring external cleaning mechanisms or additional parts
3Reliability
If the nozzle device is oriented to clean the pipe periphery, then the pipe cleaning effectiveness improves, but the coverage of the enclosed space cleaning may be reduced
Solution Approach 1:
The dual rotation system creates dynamic cleaning coverage. The nozzle device rotates about the longitudinal axis while nozzles rotate about their own axes, causing the spray pattern to sweep across both the pipe periphery and the enclosed space interior. This dynamic motion ensures comprehensive coverage of both targets without sacrificing effectiveness for either
Solution Approach 2:
The rotating nozzle device delivers periodic streams of flush liquid to different portions of the pipe and tank. During each rotation cycle, nozzles alternately contact the pipe periphery and the enclosed space interior, ensuring both surfaces receive adequate cleaning attention through repeated periodic action

AI summary
The present invention concerns a flushing device (1) comprising a flush liquid pipe (6) arranged in an enclosed space (2) with at least one flush head (7) which is substantially rotatable about the longitudinal axis (A) of the flush liquid pipe, and a nozzle device (8) arranged on said flush head, being substantially rotatable about an axis (B) extending substantially transversely to the longitudinal axis of said flush liquid pipe, having one or more nozzles (9, 11) for the provision of one or more flush liquid streams (10, 12) directed substantially against the inside of said enclosed space for the cleaning thereof. To provide a flushing device (1) which also permits cleaning of components of the flushing device which are located within the enclosed space (2), at least one of said one or more nozzles (9, 11) of the nozzle device (8) are arranged and/or formed such that at least a portion of the flush liquid streams (10 and 12) from the nozzle during at least a portion of the rotation of the nozzle device contacts the flush liquid pipe (6) along a portion of the periphery of the flush liquid pipe and such that at least said portion of the flush liquid stream from the nozzle contacts the flush liquid pipe during rotation of the flush head (7) along the entirety of, or a portion of, its periphery, thereby cleaning the flush liquid pipe.
