Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-shaft laminated spiral solid-liquid separators face issues with drive rod deformation and abrasion, especially when handling high-fiber-content materials, leading to reduced processing capacity and machine failure due to inadequate support and contact between moving parts.
Innovation Solution
A multi-shaft laminated spiral solid-liquid separator with a pendulum motion design, featuring staggered arrangement of fixed and movable rings, multiple screw shafts, and a gear transmission mechanism, where the primary drive rod is supported and equipped with eccentric devices to prevent deformation and reduce abrasion, allowing for efficient moisture drainage and increased processing capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If movable rings are driven by a rotating screw shaft, then the filtrate can be drained out while processed objects are moved towards the outlet, but abrasion occurs between the movable rings and the screw shaft
Solution Approach 1:
The patent extracts the drive function from the screw shaft by introducing an independent drive rod system. The screw shaft is removed from the driving mechanism, eliminating the source of abrasion while preserving the conveying function through the drive rod's interaction with movable rings.
Solution Approach 2:
The patent introduces drive rods as intermediary elements between the power source and movable rings. These drive rods transmit motion without direct contact between moving parts, using guide holes and positioning mechanisms to eliminate abrasion while maintaining drive functionality.
2Reliability
If an eccentric shaft is used to drive movable rings, then abrasion between movable rings and screw shaft is avoided, but deformation easily occurs and large machines cannot be driven due to high load bearing
Solution Approach 1:
The patent segments the drive system into multiple independent components: drive rod, support device, positioning mechanism, and movable rings. This segmentation distributes the load across multiple elements rather than concentrating it on a single eccentric shaft, preventing deformation while maintaining abrasion-free operation.
Solution Approach 2:
The patent transitions from a single-axis eccentric shaft mechanism to a multi-dimensional support structure where drive rods are positioned at multiple locations along the screw shaft axis. This spatial distribution adds dimensional stability and load-bearing capacity without requiring high-strength eccentric components.
3Reliability
If movable rings are driven up and down by an external driver around the periphery of the screw shaft, then abrasion is reduced, but materials accumulate on the screw shaft during high-fiber-content sludge processing, reducing processing capacity and causing overload
Solution Approach 1:
The patent removes the screw shaft from the driving function entirely, extracting its role as a drive element. This eliminates the central accumulation point for high-fiber materials, allowing uninterrupted processing capacity while maintaining the peripheral drive mechanism's abrasion-free operation.
4Strength
If a cover is provided around the upper portions of the screw shafts with movable or fixed plates on lower portions, then structural support is provided, but contact between plates and screw shafts causes abrasion
Solution Approach 1:
The patent extracts the support function from the screw shaft by implementing independent support devices positioned separately from the drive mechanism. This separation eliminates contact between support structures and driving elements, removing the source of abrasion while maintaining structural integrity.
