Portable Pump Station for Water Slurry Dewatering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dewatering systems in mining and construction sites are inefficient and costly due to the need for frequent manual removal of sand and stone material, which clogs pumps and requires multiple operators, and are not portable, leading to suboptimal cavity location and increased operational costs.
Innovation Solution
A portable pump station arrangement with a chassis for forklift access, a tank design that minimizes sediment accumulation, quick coupling connections for easy pump replacement, and a platform for elevated access, allowing for efficient and flexible operation regardless of orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stationary cavities are used for dewatering, then pumps can be installed in fixed locations, but the system becomes less adaptable as the mine front moves and cavities lose optimal positioning
Solution Approach 1:
The pump station is designed as a mobile, portable unit that can be dynamically repositioned along the mine front using a chassis with forklift entry openings. This allows the system to adapt to the moving mine front while maintaining operational functionality, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The pump station is divided into modular components including a removable tank, discharge pump, and outlet pipe system that can be independently assembled and disassembled. This segmentation enables easy transport and repositioning, improving adaptability without significantly increasing overall system complexity.
2Reliability
If manual removal of sand and stone is performed frequently, then pump clogging is prevented, but operator time and costs increase
Solution Approach 1:
The system uses gravity and tank design features to automatically separate and remove sand and stone material without requiring manual intervention. The tank geometry and outlet positioning enable self-cleaning operation, maintaining pump reliability while eliminating time-consuming manual removal tasks.
Solution Approach 2:
The tank is designed to extract and separate solid sediment material from the water slurry through gravity settling. This extraction of harmful solids prevents pump clogging and eliminates the need for frequent manual cleaning operations.
3Productivity
If multiple operators are deployed for pump maintenance, then continuous operation is maintained, but operational costs increase
Solution Approach 1:
The pump station is designed with self-monitoring and self-maintaining features that reduce the need for multiple operators. The system can detect and respond to operational issues independently, maintaining continuous productivity while reducing the quantity of human resources required.
4Adaptability or versatility
If the pump station is made portable, then optimal cavity location is maintained, but the system becomes more complex
Solution Approach 1:
The pump station incorporates a mobile chassis with forklift entry openings enabling dynamic repositioning. This dynamic capability allows the system to maintain optimal cavity location while the modular design keeps the added complexity manageable through standardized components and easy assembly.
