Conveyor Device for Non-Homogeneous Liquids with Collection Box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveying devices for non-homogeneous liquids like liquid manure and sewage sludge often experience blockages due to uncrushable solids, requiring frequent uncoupling and recoupling of suction hoses, which is inefficient and cumbersome.
Innovation Solution
A conveying device with a housing featuring an antechamber, a main chamber, a rotating suction wheel, and a comminuting device with a cutting plate having helical openings, along with a collection box in the antechamber for uncrushable foreign bodies, allowing them to be collected and easily ejected, eliminating the need for frequent hose uncoupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cutting device is used to break down solids in the conveying device, then coarse solids can be broken down to prevent damage to downstream equipment, but unbreakable solids still cause blockages requiring hose disconnection
Solution Approach 1:
The pre-chamber is segmented into a main flow area and a collection box area separated by a partition wall with openings. This segmentation allows solids to be divided into two categories: those that continue with the liquid flow and those that are collected in the box. The collection box acts as a separate compartment for accumulating unbreakable foreign objects, preventing them from causing blockages in the main conveying path.
Solution Approach 2:
The partition wall with openings serves as an intermediary structure between the main flow and the collection box. It allows the liquid and breakable solids to pass through while directing unbreakable foreign objects into the collection box. This intermediary structure efficiently separates different types of solids without requiring complete disconnection of the suction hose.
2Productivity
If unbreakable foreign objects are allowed to accumulate in the conveying device, then continuous operation is maintained, but blockages occur requiring hose uncoupling and recoupling
Solution Approach 1:
The collection box extracts and isolates unbreakable foreign objects from the main conveying stream. By providing a dedicated collection space with its own discharge opening, the system removes problematic solids without requiring interruption of the main conveying operation. The collection box can be independently accessed and emptied while the suction hose remains connected.
Solution Approach 2:
The system provides self-service by automatically separating and collecting unbreakable foreign objects during normal operation. The partition wall with openings automatically directs these objects into the collection box based on their inability to be broken down by the cutting device, eliminating the need for manual intervention to remove blockages.
3Ease of operation
If the collection box is provided with a discharge opening in the pre-chamber, then foreign bodies can be discharged without disconnecting the suction hose, but the pre-chamber structure becomes more complex
Solution Approach 1:
The pre-chamber is segmented into functional zones: a main flow area for liquid and breakable solids, and a collection box area for unbreakable foreign objects. The partition wall with openings creates a controlled separation that allows the collection box to have its own discharge opening accessible from the pre-chamber, enabling independent access without affecting the main conveying operation.
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 solution enables efficient handling of non-homogeneous liquids by preventing blockages and reducing the need for tedious hose connections, ensuring continuous operation by allowing uncrushable solids to be collected and discharged without interrupting the flow.
Implementation Method 1
a suction wheel (7) arranged in the main chamber (4) and mounted on a driven shaft (6)
Implementation Method 2
The collection box (14) is arranged below the shredding unit so that any non-shredable foreign matter falls into the collection box (14) by gravity
