Tube-Integrated Scoop Pump for Low-Level Viscous Media Conveying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveyor devices for viscous media can only operate if the medium level inside a container is higher than the scoop's edge, limiting their functionality when the medium level drops below this point.
Innovation Solution
A conveyor device with a scoop device and pump device arranged inside a tube, featuring a foot valve for medium inflow regulation and a piston that moves between retracted and extended positions, allowing for continuous medium conveyance even when the level is low, using a conveyor drive to synchronize scooping and pumping operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional ladle-based scooping device is used, then the device structure is simple, but the device cannot operate when the medium level falls to or below the rim of the ladle
Solution Approach 1:
The scooping device and pumping device are nested inside a pipe, with the scooping device positioned within the pipe and the pumping device also arranged inside the same pipe. This nested configuration allows both devices to share the same space and work in coordination, enabling operation at low medium levels while maintaining a compact overall structure.
Solution Approach 2:
The invention combines the scooping device and pumping device into a single integrated system within the pipe, where the scooping device draws medium into the pipe and the pumping device simultaneously or sequentially conveys it out. This merging of functions allows continuous operation even when the medium level is below the rim of a conventional ladle.
2Productivity
If the medium level is higher than the ladle rim, then the scooping device can convey medium, but further conveying is impossible when the medium level drops to or below the rim
Solution Approach 1:
The pipe acts as an intermediary structure that extends into the container, allowing the scooping device to reach and draw medium even when the medium level is below the rim of a conventional ladle. The pipe provides a pathway for medium to be drawn in and conveyed out, enabling operation across a wider range of medium levels.
3Power
If a piston chamber with inflow and outflow areas is used, then medium can be conveyed under pressure, but the device becomes more complex
Solution Approach 1:
The piston chamber is integrated within the scooping device structure, combining the functions of medium intake, compression, and discharge in a single compact unit. The piston rod connects the scooping device to the conveying drive, merging the scooping and pumping functions into one coordinated system that generates conveying pressure without requiring separate complex subsystems.
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
Enables nearly complete removal of free-flowing media from containers, maintaining operation even at low medium levels and enhancing delivery efficiency by regulating flow direction and pressure, while preventing backflow and overload through check valves and relief openings.
Implementation Method 1
a piston is arranged in the piston chamber which divides the piston chamber into an inflow area and an outflow area, wherein the inflow area and the outflow area can be connected or are connected via the piston, and the piston can be moved between a retracted position and an extended position inside the piston chamber
Implementation Method 2
the scooping device has a foot valve which is arranged at a second end of the pipe, by means of which a foot valve can be used to control an inlet for an inflow of medium into a piston chamber
