Grinder Pump Basin Bracket Mounting and Cutter Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current grinder pump basin systems face issues with clogging due to solid and fibrous materials, vibration, and inefficiency in grinding, leading to operational interference and reduced longevity.
Innovation Solution
A novel grinder pump basin system design where the pump is secured to a bracket above the basin's bottom surface, with a directional flow path and cutter plate/cutter blade configuration that directs waste water and solids away from the pump, preventing direct impact and enhancing grinding efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the grinder pump is attached directly to the cover plate of the basin, then the pump is securely positioned, but solid and fibrous materials can deposit on the pump and float switches causing clogging
Solution Approach 1:
The patent introduces a bracket as an intermediary component between the cover plate and the grinder pump. The bracket is attached to the cover plate while the pump is mounted to the bracket, creating a mediating structure that prevents direct contact between the pump and incoming waste water flow, thereby eliminating the clogging issue while maintaining secure positioning
Solution Approach 2:
The mounting system is segmented into separate components: the cover plate, the bracket, and the grinder pump. This segmentation allows the bracket to serve as a dedicated mounting structure that can be positioned to optimize flow patterns and prevent solids from reaching the pump, while the pump itself remains securely mounted without direct attachment to the cover plate
2Productivity
If the grinder pump is positioned at the bottom of the basin, then it can effectively pump waste water, but sediment builds up below the pump interfering with operation
Solution Approach 1:
The patent elevates the grinder pump from the bottom surface of the basin to a higher position using the bracket, changing the vertical dimension of pump placement. This dimensional change allows waste water to flow underneath the pump while it grinds solids, preventing sediment accumulation below the pump and maintaining operational efficiency
3Productivity
If the grinder pump grinds solid or semisolid materials, then waste water is processed, but significant vibration and torquing occur reducing system longevity
Solution Approach 1:
The bracket serves as a vibration-isolating intermediary between the grinder pump and the cover plate. By mounting the pump to the bracket rather than directly to the cover plate, the bracket absorbs and dampens the significant vibration and torquing generated during grinding operations, protecting the cover plate and other system components from damage and extending overall system longevity

AI summary
A grinder pump basin system is provided which includes a basin; a cover plate; a bracket secured to the cover plate; and a grinder pump with cutter plate with openings and a cutter blade secured to the bracket above a bottom surface of the basin. The openings in the cutter plate have an unique shape which assists in the cutting of material which flows through an inlet of a grinder pump. The shape of the cutter blade cooperates with the openings in the cutter plate such that solids are forced between these respective components and thereby are efficiently cut into small pieces for passing through the openings and for discharge from the grinder pump basin system.
