A Lance Canister Dispensing Assembly with Mandrel Rinsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatus for transferring liquid contents from herbicide, pesticide, or fertilizer canisters into larger vessels often face issues with fluid dispensation due to incised floor edges impinging on cutting blades, which impedes downward emission and interferes with subsequent rinsing processes.
Innovation Solution
The use of an 'A' lance with sharpened legs and a horizontally extending bar that pierces and incises the canister floor, allowing for efficient dispensation and subsequent rinsing by emitting water jets through a mandrel and sprinkler head configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the canister floor is incised by cutting blades, then the liquid contents can be dispensed into the tank, but the incised floor edges impinge against the cutting blades and impede the downward emission of fluid
Solution Approach 1:
The canister floor is divided into multiple segments by incising it with cutting blades arranged in a star pattern. This segmentation allows the floor to be divided into wedge-shaped sections that can be easily separated and dispense liquid contents into the tank without impingement issues.
Solution Approach 2:
A mandrel is introduced as an intermediary component that supports the incised floor sections from below. The mandrel prevents the cut edges from contacting the cutting blades by providing a surface for the floor sections to rest on, thereby eliminating impingement and ensuring smooth fluid flow.
2Productivity
If the canister floor is incised to enable dispensation, then liquid contents can flow downward, but the incised edges resist and interfere with upward and inward flows of rinsing water
Solution Approach 1:
The mandrel serves as an intermediary that facilitates both dispensation and rinsing operations. During rinsing, the mandrel supports the floor sections to allow rinsing water to flow upward and inward without resistance from impinged edges, thereby improving rinsing efficiency while maintaining dispensation effectiveness.
Solution Approach 2:
The system transitions between two operational states: during dispensation, the floor sections are held in a position that facilitates downward flow; during rinsing, the same structure allows upward and inward flow of water. The mandrel enables this dynamic adaptation to different operational requirements.
3Loss of time
If cutting blades are used to incise the canister floor, then the contents can be transferred quickly, but the impingement of incised edges against blades interferes with downward flows of rinsed residual chemical
Solution Approach 1:
The mandrel acts as a mediator that eliminates interference with the downward flow of rinsed residual chemical. By supporting the incised floor sections, the mandrel prevents contact between the cut edges and cutting blades, ensuring complete rinsing without compromising the quick transfer achieved through incision.
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
Facilitates smooth dispensation of liquid contents into the tank and effective rinsing of residual chemicals by minimizing impingement issues and enhancing fluid flow and rinsing efficiency.
Implementation Method 1
Upon downwardly thrusting or driving a canister's floor against such sharpened point, a hole within the floor is formed, and upon further downward driving, the sharpened edges of the 'A' lance's blade configured legs effectively incise and divide or segment the canister's floor into a plurality of flexible or bendable leaf sections
Implementation Method 2
the bore position above the canister's floor allows the water jets to efficiently rinse the walls and floor of the canister. The mandrel configured 'A' bar is preferably adapted to function as a sprinkler head, and further preferably as a rotatable sprinkler head
Implementation Method 3
the rinsing means are adapted for emitting rinsing water into the interior volume of a canister for rinsing therefrom chemical residue such as herbicide, pesticide, or fertilizer residues. The rinsing means are preferably adapted for emitting the rinsing water in the form of jets which extend from the 'A' lance's bar component
