Solids Distributor Rotor Radial Removal Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Distributor devices for solids-containing liquids face issues with clogging due to solids in the liquid and wear of cutting blades, leading to reduced functionality and increased maintenance complexity, particularly in agricultural applications where precise distribution is required.
Innovation Solution
A distributor device design featuring a detachable connecting part between the rotor and blade drive shaft, allowing radial removal of the rotor through a side wall opening, reducing the need for axial movement and enabling easier maintenance and replacement of cutting blades without disassembling the end wall, thus minimizing force and time required for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the rotor is axially removed from the distribution chamber by disassembling the end wall, then the cutting blades can be replaced, but the mobility of the end wall is restricted and great force and time are required for removal and reassembly
Solution Approach 1:
The rotor is divided into modular components (rotor body, connecting part, cutting blades) that can be independently accessed and replaced. The connecting part serves as a detachable interface between the rotor and drive shaft, allowing the rotor to be segmented into removable sections for easier maintenance.
Solution Approach 2:
The rotor removal path is changed from axial direction (through end wall) to radial direction (through side wall opening). This dimensional change in the removal trajectory eliminates the need to disassemble the end wall and its connected hoses, significantly reducing maintenance time and force requirements.
2Ease of repair
If the end wall is disassembled for rotor removal, then the rotor can be accessed, but the connected hoses experience increased stress and mobility is restricted
Solution Approach 1:
The rotor extraction path is routed through the side wall opening rather than through the end wall. This extracts the rotor removal operation from the constrained axial path (which requires end wall disassembly and hose movement) and provides an alternative radial path that leaves the end wall and hoses in their fixed positions, eliminating stress on the hoses.
3Reliability
If cutting blades are worn and need replacement, then functionality is restored, but regular renewal requires significant force and time effort
Solution Approach 1:
The connecting part is designed with detachable connections (screw connections or form-fit connections) that allow dynamic assembly and disassembly. This enables the rotor to be easily connected and disconnected from the drive shaft, transforming the static, fixed rotor design into a dynamic, maintainable system where cutting blades can be quickly replaced without permanent fixation.

Function Achieved in This Case
This design enhances the accessibility and maintainability of cutting blades, reduces wear-related issues, and decreases the effort needed for maintenance, while maintaining plane parallelism and reducing stress on hoses, thereby extending their service life and improving the overall efficiency of the distribution process.
Implementation Method 1
the cutting blade is moved relative to the perforated disc to create this shear action
Implementation Method 2
a clamping device which is designed to effect a contact force between the first cutting blade and the first perforated blade disc

AI summary
A distributor device for solids-containing liquids includes a distribution chamber with an inlet opening which leads to a chamber interior space of the distribution chamber, wherein the distribution chamber has a first end wall with several connection ports and a first side wall arranged laterally to the end wall. The distributor device also includes a connecting part connecting the rotor and the blade drive shaft, which connecting part is detachably connected to the rotor and/or to the blade drive shaft, wherein a movement of the rotor is guided by the connecting part relative to the first perforated blade disk. The distribution chamber has at least one closable opening which is located in the first side wall, wherein the opening is designed at least so large that the rotor is removable from the distribution chamber through the opening.
