Horizontal Agitator Cable Guide Eliminates Post Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing horizontal agitators in clarifiers face inefficiencies due to flow resistance caused by the post guiding the assembly unit, which hinders effective horizontal recirculation of water and requires complex maintenance procedures.
Innovation Solution
The horizontal agitator eliminates the need for a post by using cables to guide the assembly unit, allowing for efficient horizontal recirculation and simplified maintenance through a cable system with winches and coupling arrangements that enable easy lifting, lowering, and coupling of the assembly unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a post is used to guide the assembly unit, then the assembly unit can be vertically displaced and guided, but flow resistance is caused that hinders efficient horizontal recirculation of water
Solution Approach 1:
The invention removes the post from the system entirely and replaces it with a cable winch mechanism. The post is extracted as a harmful element causing flow resistance, and its guiding function is transferred to a flexible cable system that can be retracted or positioned to minimize interference with water flow patterns in the clarifier.
Solution Approach 2:
A cable is introduced as an intermediary element between the winch and the assembly unit. This cable serves as the guiding medium, replacing the solid post with a flexible connection that creates minimal flow resistance while still providing the necessary guidance and support for vertical displacement of the assembly unit.
2Strength
If a post is used to guide the assembly unit, then structural support is provided, but the structure becomes more complex and maintenance becomes difficult
Solution Approach 1:
The rigid post structure is segmented into discrete components: a winch mechanism, a cable, and an assembly unit with attachment points. This segmentation allows each component to be independently selected, installed, and maintained, reducing overall system complexity while maintaining structural support functionality.
Solution Approach 2:
The static post structure is replaced with a dynamic cable-winching system that can adapt its configuration. The cable can be tensioned, relaxed, retracted, or extended as needed, providing structural support only when required while allowing flexibility for maintenance removal and storage when not in use.
3Ease of operation
If a post is used to guide the assembly unit, then guidance is provided, but maintenance and repair of the assembly unit become difficult
Solution Approach 1:
The assembly unit is pre-equipped with attachment points or coupling mechanisms designed specifically for quick connection to and disconnection from the cable system. This preliminary preparation enables rapid maintenance access without requiring complex disassembly procedures or specialized tools.
Solution Approach 2:
The guidance system transitions from a fixed post requiring the assembly unit to be permanently mounted or difficult to remove, to a dynamic cable system that can be quickly disconnected. The assembly unit can be easily lifted out of the clarifier by winching the cable, accessed for maintenance, and then reinstalled by reversing the process.

AI summary
The invention relates to a horizontal agitator for producing a flow in a clarifier, a submersible motor (1) and a propeller (3) drivingly connected thereto forming an assembly unit (M), wherein a receiving portion (A) for removably attaching the assembly unit (M) is provided and can be supported on the bottom (Bo) of the clarifier, and wherein a guide for guiding the assembly unit (M) along a substantially vertical movement path between a surfacing position above a maximum nominal sewage level (N) defined for the clarifier and the receiving portion (A) is provided. In order to improve the efficiency of the horizontal agitator and to reduce complexity of manufacture, the guide is formed by at least one first cable (S) extending between the surfacing position and the receiving portion (A).
