Chemical Feeder Support Plate with Arcuate Extensions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chemical feeders face variability in dissolving solid treatment chemicals, leading to inconsistent concentrations in treated liquids, which can result in reduced sanitizing properties or toxicity, making it challenging to maintain a controllable and reproducible level of treatment chemicals.
Innovation Solution
A chemical feeder design featuring a support plate with arcuate or spiral extensions that facilitate the dissolution of solid chemicals by directing the feed liquid through apertures, ensuring consistent contact and mixing, thereby maintaining a controlled concentration of dissolved chemical material in the treated liquid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solid treatment chemical is placed in chemical feeder to contact with liquid, then treated liquid composition is produced, but variability in dissolution rate causes undesirable variation in treatment chemical concentration
Solution Approach 1:
The support plate is segmented into multiple functional zones: a base plate with apertures for liquid distribution, and multiple arcuate extensions that create channels and compartments. This segmentation divides the dissolution process into multiple controlled pathways, ensuring uniform liquid distribution across the solid chemical and consistent dissolution rates.
Solution Approach 2:
The invention transitions from a flat support plate to a three-dimensional structure with arcuate extensions that rise vertically from the base plate. These extensions create channels and compartments that guide liquid flow in multiple directions, adding vertical and radial dimensions to the dissolution process for improved concentration control.
2Manufacturing precision
If support plate with arcuate extensions is used to improve dissolution consistency, then concentration control is enhanced, but device complexity increases
Solution Approach 1:
The support plate incorporates arcuate (curved) extensions instead of straight geometric shapes. These curved structures naturally guide liquid flow in circular patterns across the solid chemical, improving dissolution uniformity through streamlined fluid dynamics while maintaining manufacturability via standard molding processes.
3Reliability
If feed liquid flows through apertures to contact solid chemical, then treated liquid is formed, but inconsistent contact leads to variable concentration
Solution Approach 1:
The arcuate extensions act as intermediary structures between the liquid feed and the solid chemical. They create channels that mediate the liquid flow path, ensuring consistent distribution of liquid across the chemical while protecting the aperture system from clogging and maintaining stable flow patterns.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures a consistent and reproducible concentration of treatment chemicals, enhancing sanitizing properties while preventing toxicity and aesthetic issues by ensuring uniform dissolution of solids.
Implementation Method 1
At least some of the feed liquid introduced through the inlet flows through the plurality of arcuate channel apertures, contacts the solid chemical material supported on or above the support plate, and forms the treated liquid
Implementation Method 2
ensuring consistent contact and mixing, thereby maintaining a controlled concentration of dissolved chemical material in the treated liquid

AI summary
A chemical feeder includes a support plate that is positioned within the housing chamber of the chemical feeder is described. The support plate includes a base plate having an upper surface that has one or more extensions that extend upward from the upper surface. The extensions can, with some embodiments, be in the form of arcuate extensions that can together define an impeller pattern or a spiral extension that defines a spiral channel. The upper surface of the base plate and/or the one or more extensions are adapted to support a solid chemical material thereon. The support plate further includes a plurality of arcuate channel apertures or spiral channel apertures that extend through the base plate. A feed liquid introduced into the housing chamber flows through at least one of the plurality of arcuate/spiral channel apertures and contacts the solid chemical material to form a treated liquid.
