Solution Overview
Problem
Existing solid-liquid separators face issues with drive rod deformation and abrasion, especially when handling high-fiber-content sludge, leading to reduced processing capacity and machine failures due to inadequate support and design flaws in drive mechanisms.
Innovation Solution
A multi-shaft laminated spiral solid-liquid separator design featuring staggered fixed and movable rings, multiple screw shafts, and a dual-drive rod system with eccentric devices and gear transmission mechanisms to prevent deformation and abrasion, allowing for efficient handling of high-fiber-content materials and improved moisture drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If movable rings are driven by a single screw shaft, then the structure is simple, but the drive rod deforms and bends under high load
Solution Approach 1:
The single screw shaft is divided into multiple screw shafts (first screw shaft, second screw shaft, etc.), each independently supporting the movable rings. This segmentation distributes the mechanical load across multiple components, preventing drive rod deformation while maintaining structural simplicity through modular replication.
2Device complexity
If movable rings contact the screw shaft directly, then the drive mechanism is simple, but abrasion occurs between movable rings and screw shaft
Solution Approach 1:
A linear guide device is introduced as an intermediary component between the movable rings and the screw shafts. The linear guide device guides the movable rings along the screw shafts without direct contact, eliminating abrasion while maintaining the simplicity of the drive mechanism through a low-friction interface.
3Productivity
If high-fiber-content sludge is processed, then the processing capacity increases, but materials accumulate on the screw shaft and cause overload
Solution Approach 1:
The screw shafts rotate at controlled speeds to create mechanical vibration and tumbling motion of the sludge material. This vibration prevents high-fiber-content materials from adhering to and accumulating on the screw shaft surfaces, maintaining processing capacity while preventing overload conditions through continuous material loosening and redistribution.
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 design effectively prevents drive rod deformation and abrasion, enhances processing capacity, and ensures thorough moisture drainage by using multiple screw shafts and a dual-drive rod system, which also reduces the risk of machine failure and improves operational efficiency.
Implementation Method 1
Each of the support devices has a linear guide device and a giving-way hole, the guide rod passes through the linear guide device, the secondary drive rod passes through the giving-way hole... so that the secondary drive rod drives the one end of the movable rings to make a circular motion while the guide rod drives the another end of the movable rings to move up and down by the linear guide device
Implementation Method 2
one or more eccentric devices are provided on the primary drive rod... Each of the eccentric devices is fixedly connected a drive sheet, the drive sheet and a corresponding one of the movable rings are integrally formed, so that each of the eccentric devices is connected to the secondary drive rod via the drive sheet and the movable ring
