Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamella thickeners face issues such as complex assembly processes, unstable support, deformation, and reduced efficiency due to the use of individual inclined plates, which limit their operational stability and long-term performance in solid-liquid separation processes.
Innovation Solution
The vibrating inclined plate box settlement separator features a modular design with securely connected inclined plate boxes supported by spring assemblies and a tapered hopper system, allowing for efficient installation, increased stability, and enhanced separation efficiency through adjustable vibration frequencies and intermittent vibration modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional inclined plates are used in lamella thickeners, then settlement area can be enlarged, but the assembly process becomes complex and the structure becomes unstable
Solution Approach 1:
The patent combines multiple inclined plates into an integrated inclined plate assembly where plates are connected through ribs and support structures, forming a unified module that simplifies installation while maintaining large settlement area. The assembly is treated as a single unit rather than separate plates requiring individual installation.
Solution Approach 2:
The inclined plate assembly is divided into modular sections with standardized ribs and support structures, allowing for easier fabrication and assembly. The segmentation into manageable modules reduces overall assembly complexity while maintaining the extended settlement area.
2Area of stationary object
If conventional inclined plates are used in lamella thickeners, then settlement area can be enlarged, but the plates deform easily and reliability decreases
Solution Approach 1:
The assembly is segmented into sections connected by ribs and support structures, distributing mechanical loads across multiple points rather than concentrating stress on individual plates. This segmentation prevents deformation while maintaining the total settlement area.
Solution Approach 2:
The inclined plates are pre-assembled into a rigid framework with ribs and support structures before installation, ensuring proper alignment and structural integrity. This preliminary assembly prevents deformation during operation by establishing correct geometric relationships in advance.
3Reliability
If vibrating mechanism is added to prevent plate deformation, then reliability improves, but device complexity increases
Solution Approach 1:
A vibrating mechanism is integrated into the inclined plate assembly to prevent material accumulation and maintain separation efficiency. The vibration is applied directly to the plate structure, using the existing framework rather than adding separate complex mechanisms, thus improving reliability with minimal increase in overall device complexity.

Function Achieved in This Case
This design simplifies the assembly process, prevents deformation, and significantly improves separation efficiency by creating multiple narrow settlement channels, extending the equipment's wear-out period and ensuring smooth operation with reduced material loss, while also enabling effective discharge of high-concentration underflows.
Implementation Method 1
The supporting platforms (1-1) have several spring assemblies (3), on which mounted several inclined plate box modules (4) that can vibrate separately
Implementation Method 2
The vibrator bracket (4-7) is welded at the center-of-gravity position of the settlement module... and on the two sides of the frame. The bottom plate of the vibrator (4-8) is welded on the top of the vibrator bracket (4-7), and the vibrator (4-9) is fastened onto the bottom plate (4-8) with screws and bolts
Implementation Method 3
The inclined plate box (4-2) is rectangular, with a length equal to that of the sloped side (4-1-1) of the parallelogram frame (4-1). The top (4-2-1) and bottom (4-2-2) panels of the inclined plate box (4-2) consists of the titled settlement plate
Implementation Method 4
Each inclined plate box (4-2) forms several long and narrow independent settlement channels (4-2-5)

AI summary
The invention involves a vibrating inclined plate box settlement separator, which is used for the liquid-solid separation, particularly applicable to high-efficiency settling concentration and separation of solid particles from liquid or water. The separator consists of an upper box and a lower tapered hopper. The upper box and the lower tapered hopper are connected securely to each other and sealed. The upper box is a rectangular or square steel-structured box with two supporting platforms on both of its sides, on which several spring assemblies are installed. The inclined plate box modules which can independently vibrate are installed on the spring assemblies. The feed box is placed on top of or inside the upper box. An overflow collect chute is welded on the side of the box frame opposite to the feed box.
