Concrete Chute Gap Separator for Aggregate-Free Cement Slurry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete separating devices fail to effectively separate cement slurry from aggregate in concrete mix, lacking a mechanism to direct cement slurry into a receptacle while excluding aggregate.
Innovation Solution
A bar is inserted between adjacent sections of a concrete chute to create a gap, with a funnel positioned below to collect cement slurry, excluding aggregate and directing it into a receptacle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a bar is inserted to create a gap in the concrete chute, then cement slurry can pass through to be separated, but aggregate is blocked and cannot pass through
Solution Approach 1:
The concrete chute is divided into sections with a gap created by the bar, segmenting the flow path to separate cement slurry from aggregate based on particle size
Solution Approach 2:
The bar acts as an intermediary element inserted between chute sections to create the separating gap, while the funnel serves as an intermediary to collect and direct the separated slurry
2Ease of operation
If a funnel is attached to collect cement slurry, then slurry can be directed into a receptacle, but the device complexity increases
Solution Approach 1:
The funnel is attached directly to the bar structure, merging the separation element (bar) with the collection element (funnel) into a single integrated device
Solution Approach 2:
The funnel's wide opening automatically captures slurry passing through the gap, and gravity naturally directs it into the receptacle below, requiring no additional active components
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
Efficient generation of cement slurry free of aggregate, suitable for finishing work, by creating a gap in the chute and using a funnel to collect and contain the slurry.
Implementation Method 1
The bar is sized so that aggregate of a concrete mix, which passes through the concrete chute, is selectively excluded from passing through the gap. Cement slurry, which is substantially free of aggregate, is generated from the concrete mix and passes through the gap.
Implementation Method 2
A funnel is attached to the bar so that the funnel is positioned below the gap upon insertion of the bar between the adjacent sections of the concrete chute. The funnel is configured to direct the cement slurry into a receptacle

AI summary
A concrete mix separating device for generating cement slurry from a concrete mix includes a bar, which is insertable between adjacent sections of a concrete chute so that a gap is created between the adjacent sections. The bar is sized so that aggregate of a concrete mix, which passes through the concrete chute, is selectively excluded from passing through the gap. Cement slurry, which is substantially free of aggregate, is generated from the concrete mix and passes through the gap. A funnel is attached to the bar so that the funnel is positioned below the gap upon insertion of the bar between the adjacent sections of the concrete chute. The funnel directs the cement slurry into a receptacle, such as a bucket or a wheelbarrow, which is positioned below the funnel.
