Segmented Distributor Plate with Movable Valve Plates for Water Softener Resin Scrubbing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current distributor plates in water softeners are inefficient during backwash or upflow operations, leading to minimal scrubbing of the resin bed, and existing solutions like turbulators are not suitable for abrasive media or gravel under-beds, causing reduced efficiency and potential resin migration.
Innovation Solution
A segmented distributor plate with movable valve plates that allow unobstructed downflow and block flow during upflow, enhancing scrubbing by altering the flow distribution and using a material with lower specific gravity than the treated fluid to facilitate sealing during backwash.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional distributor plate is used to allow bidirectional flow, then service flow is relatively efficient, but backwash flow is inefficient with minimal scrubbing
Solution Approach 1:
The distributor plate incorporates movable valve plates that automatically change position based on flow direction. During backwash, valves open to create concentrated flow paths for enhanced scrubbing; during service flow, valves close to maintain uniform distribution. This dynamic adaptation resolves the contradiction between scrubbing efficiency and flow uniformity.
Solution Approach 2:
The system changes the flow distribution parameters dynamically by using valve plates that alter the opening configuration based on flow direction. The valve plates transition between open and closed states, changing the flow path characteristics to optimize for either backwash scrubbing or service flow uniformity as needed.
2Productivity
If a turbulator with check valves is used to enhance backwash scrubbing, then scrubbing is improved, but the system becomes incompatible with abrasive media and gravel under-beds
Solution Approach 1:
The distributor plate is segmented into multiple independent valve plates that can be selectively positioned. This segmentation allows the system to achieve concentrated flow paths for scrubbing without requiring the complex check valve mechanisms of turbulators, thereby maintaining compatibility with abrasive media and gravel under-beds while still improving backwash efficiency.
Solution Approach 2:
The invention extracts the essential function of flow concentration for scrubbing from the complex turbulator assembly with multiple check valves. By using simpler movable valve plates on a segmented distributor, the system achieves the scrubbing enhancement without the compatibility problems associated with traditional check valve mechanisms.
3Speed
If valve plates are made lighter to facilitate easier movement during flow direction changes, then responsiveness is improved, but sealing capability during backwash may be compromised
Solution Approach 1:
The valve plates are designed with buoyancy forces that counteract their weight. During backwash flow, the upward buoyant force helps lighter valve plates maintain sealing contact with the distributor plate surface, compensating for their reduced weight and ensuring reliable sealing despite faster response characteristics.

AI summary
A distributor plate for a resin tank of a fluid treatment device such as a water softener includes a central hub, an outer ring, a plurality of ribs extending between the hub and the ring and dividing the distributor plate into discrete segments, and a slotted plate connected therebetween. The distributor plate separates the resin bed from a lower end of the resin tank. The distributor plate further comprises at least one valve plate coupled to an underside of the distributor plate over at least one segment thereof. The valve plate is constructed from a material configured to float in the fluid being treated and is movable between a raised position during upflow and a lowered position during downflow. In this manner, the valve plate acts like a check valve to regulate the manner in which fluid flows through the distributor plate during upflow and downflow, improving resin scrubbing during upflow.
