Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of dry stabilizers in road bed treatment generates fugitive dust, which is harmful and creates cleanup issues, limiting the application to open areas and necessitating the development of a more effective slurry distribution method to address dust problems and ensure proper mixing and contamination prevention.
Innovation Solution
A slurry spreader apparatus with a trough attached to a cement truck's discharge chute, featuring a flange to prevent spillage, an enclosed basin with adjustable drainage nozzles for efficient distribution, and a screen to filter the slurry, ensuring homogeneous distribution and minimizing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If dry stabilizer powder is applied to the road base, then the road bed stabilization is achieved, but fugitive dust is generated which is harmful and creates cleanup problems
Solution Approach 1:
The invention changes the physical state of the stabilizer from dry powder to slurry form by mixing with water. This parameter change eliminates dust generation while maintaining the stabilization function, as the slurry can be applied without creating airborne particles.
Solution Approach 2:
The invention uses hydraulic principles by forming and distributing slurry through a spreading apparatus. The slurry is pumped and distributed in liquid form, which prevents dust generation entirely while achieving the same road bed stabilization effect.
2Object-generated harmful factors
If slurry is used instead of powder to eliminate dust, then dust problems are eliminated, but the slurry may be imperfectly mixed and contain debris
Solution Approach 1:
The invention incorporates a screening mechanism that filters the slurry before distribution. This preliminary action removes debris and ensures proper mixing quality, addressing the contamination issue while maintaining the dust-free advantage of slurry application.
3Manufacturing precision
If a slurry spreader with enclosed basin and filtration is used, then slurry quality is maintained and distribution is improved, but the device complexity increases
Solution Approach 1:
The invention divides the spreader into modular components: a receiving hopper, an enclosed basin with screen, and a distribution system with nozzles. This segmentation allows for easier maintenance, cleaning, and operation while achieving improved slurry distribution uniformity through the enclosed design and filtration.
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 slurry spreader effectively prevents dust generation, ensures efficient and uniform slurry coverage, and allows for quick attachment and detachment, making it suitable for urban areas while maintaining slurry quality.
Implementation Method 1
The upper end of the trough may include a flange configured to extend under the discharge chute and prevent spillage therefrom
Implementation Method 2
The slurry spreader may include a screen attachment that covers the aperture and filters the slurry
Implementation Method 3
A plurality of adjustable drainage nozzles may be disposed along the bottom of the enclosed basin that concurrently distribute the slurry to a plurality of locations
Implementation Method 4
An aperture formed into the enclosed basin may enable the slurry to flow from the trough into the enclosed basin
