Horizontal Agitator Flow Guide Motor Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing horizontal agitators for clarifiers face inefficiencies in producing horizontal flow due to frame-induced flow resistance, which limits their operational efficiency and requires costly and complex support structures.
Innovation Solution
The horizontal agitator supports the submersible motor via at least two flow guide elements, eliminating the need for a frame and enhancing flow efficiency, with angled flow guide elements and a carrier plate forming a stable tunnel-like structure, and includes a detachable assembly unit for easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a frame is used to support the submersible motor, then the motor can be stably supported, but flow resistance increases and efficiency decreases
Solution Approach 1:
The invention extracts and removes the frame structure from the support system, replacing it with flow guide elements that serve dual purposes. The frame is completely taken out of the system, eliminating its harmful flow resistance effect while the motor support function is maintained through the alternative flow guide element configuration.
Solution Approach 2:
The flow guide elements are designed to perform multiple functions: they guide the water flow to reduce resistance, support the submersible motor structurally, and position the propeller assembly. This multi-functionality eliminates the need for a separate frame structure, resolving the contradiction between support stability and flow resistance.
2Reliability
If a frame is used to support the submersible motor, then the motor can be stably supported, but device complexity and cost increase
Solution Approach 1:
The frame structure is extracted and removed from the design, simplifying the overall device complexity. The support function is achieved through integrated flow guide elements that are part of the existing hydrodynamic structure, eliminating the need for additional frame components.
Solution Approach 2:
The support function previously requiring a separate frame is merged into the flow guide elements. These elements simultaneously perform flow guidance and structural support tasks, reducing the total number of components and simplifying the device structure while maintaining reliability.
3Stability of the object's composition
If the assembly unit is permanently fixed to the mount, then structural stability is improved, but maintenance and repair become difficult
Solution Approach 1:
The connection between the assembly unit and mount is made dynamically adjustable rather than permanently fixed. The coupling device allows the assembly unit to be easily detached and reattached, providing operational flexibility that maintains structural stability during use while enabling simple maintenance and repair operations.
Solution Approach 2:
The system is segmented into separable components: the assembly unit (motor and propeller) can be detached from the mount using the coupling device. This segmentation allows the assembly unit to be removed for maintenance while the mount remains in place, balancing structural stability with ease of repair.

AI summary
The invention relates to a horizontal agitator for producing a flow in a clarifier, a propeller being connected to a submersible motor which is axially offset in relation thereto, wherein the propeller and the submersible motor are designed such that a flow in a direction from the propeller towards the submersible motor is produced when the submersible motor is operated, and wherein plate-shaped flow guide elements are provided downstream of the propeller and extend in at least an axial plane that runs substantially parallel to the propeller axis. In order to improve the efficiency of the horizontal agitator, it is proposed in accordance with the invention to support the submersible motor on a bottom of the clarifier via at least two first flow guide elements.
