Rotary Disk Filter Spray Nozzle Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary disk filters for wastewater treatment have complex maintenance due to non-detachable spray nozzle sections, making it difficult to remove and replace nozzles without damage.
Innovation Solution
The design incorporates pivotable spray nozzle tubes with interlocking connections that allow easy attachment and detachment of spray nozzle sections, enabling quick maintenance without tools, and features spray nozzles with separate components that can be easily connected and disconnected from the tubes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spray nozzle sections are non-detachably mounted on spray nozzle tubes, then the connection is secure during operation, but maintenance becomes complex and requires tools for removal
Solution Approach 1:
The spray nozzle is divided into multiple detachable sections (first spray nozzle section, second spray nozzle section, etc.) that can be separated from each other and from the spray nozzle tube. Each section has connection elements (protrusions and recesses) that enable tool-free attachment and detachment while maintaining secure connection during operation. This segmentation allows individual sections to be removed for maintenance without requiring tool intervention.
Solution Approach 2:
The connection system transitions from a static non-detachable mounting to a dynamic detachable connection. The spray nozzle sections are designed with movable connection elements (latching mechanisms with actuating sections) that allow the nozzle sections to be easily attached and detached from the spray nozzle tube during maintenance operations, while providing secure connection during filtration operation.
2Strength
If spray nozzle sections are permanently fixed to tubes, then structural integrity is maintained, but nozzle replacement requires damage risk and complex procedures
Solution Approach 1:
The spray nozzle system is segmented into replaceable sections that connect to the spray nozzle tube through standardized connection elements. Each spray nozzle section can be independently removed and replaced without risking damage to the spray nozzle tube or other components. The connection elements (protrusions fitting into recesses with latching mechanisms) provide secure attachment that maintains structural integrity during operation while enabling easy replacement.
Solution Approach 2:
The spray nozzle sections are designed as recoverable components that can be removed, inspected, cleaned, or replaced without damaging the spray nozzle tube or other permanent components. The detachable connection system allows used nozzle sections to be separated and replaced with new or refurbished sections, extending the service life of the overall spray nozzle arrangement while maintaining structural integrity.
3Stability of the object's composition
If multiple spray nozzle sections are connected non-detachably, then the assembly is stable, but maintenance requires tool intervention and time
Solution Approach 1:
The spray nozzle is segmented into multiple independently detachable sections, each with its own connection elements (protrusions and recesses with latching mechanisms). This segmentation allows any single section to be quickly removed and replaced without requiring tools or disassembling the entire assembly. The connection elements provide stable assembly during operation while enabling rapid maintenance intervention.
Solution Approach 2:
The spray nozzle sections are designed with self-latching connection mechanisms that automatically secure sections to the spray nozzle tube without requiring tools for assembly. The latching mechanisms include actuating sections that can be manually operated to release the latches, enabling quick maintenance. This self-service design eliminates the need for tool intervention while maintaining stable assembly during operation.
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 design simplifies maintenance by allowing spray nozzles to be removed and replaced easily, reducing maintenance complexity and costs while ensuring a secure connection during operation.
Implementation Method 1
The spray nozzle tubes each have multiple spray nozzles, by means of which a cleaning liquid fed to the spray nozzle tubes during the operation of the spray nozzle arrangement can be sprayed onto the outer side of a filter surface facing the spray nozzle.

AI summary
A rotary disk filter includes a drum and filter disks. Each filter disk has an inner hollow space, at least a portion of which is delimited by filter surfaces, wherein the hollow spaces are fluidically connected to the drum such that the waste water can flow from the interior of the drum into the hollow spaces and, from there, the filtrate can flow across the filter surfaces toward the outside. The rotary disk filter also has a spray nozzle arrangement including spray nozzle tubes and spray nozzles mounted on the spray nozzle tubes. In one aspect, the spray nozzles each have two spray nozzle sections (each having at least one nozzle head), and an interlocking connection, by means of which the spray nozzle sections are connected to the spray nozzle tubes. The spray nozzles can be removed from the spray nozzle tube once the interlocking connection has been released.
