Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid separating systems face issues with remoistening and inefficient drying rates due to surface tension and uneven pressure distribution, leading to mechanical damage and high energy consumption, making it difficult to achieve high dry matter percentages for effective litter use.
Innovation Solution
A liquid separating device with a cascading configuration of liquid separation assemblies, where each stage's passage narrows to increase thickness and pressure, using guiding assemblies to redistribute matter uniformly, and employing perforated rollers with adjustable speed and drainage holes to minimize remoistening and maximize water extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If compression pressure is increased to improve water extraction, then liquid separation efficiency is improved, but mechanical damage to fiber and energy consumption increase
Solution Approach 1:
The compression process is divided into multiple stages with progressively narrower passages (first passage, second passage, third passage). Each stage extracts liquid at different pressure levels, avoiding the need for excessive single-stage compression that would damage fiber. The segmentation of compression stages allows efficient liquid separation while maintaining fiber integrity.
2Productivity
If compression pressure is increased to improve water extraction, then liquid separation efficiency is improved, but energy consumption increases
Solution Approach 1:
The compression process is divided into multiple stages with progressively narrower passages. Each stage extracts liquid at different pressure levels, avoiding the need for excessive single-stage compression that would consume excessive energy. The multi-stage approach distributes energy consumption across stages, improving overall efficiency.
Solution Approach 2:
The passage width dynamically decreases from the first passage to the third passage, creating progressively higher compression pressures only where needed. This dynamic structure allows efficient liquid extraction at each stage without applying excessive pressure throughout the entire system, reducing unnecessary energy consumption.
3Productivity
If roller porosity is increased to improve liquid extraction, then water removal efficiency is improved, but remoistening increases
Solution Approach 1:
The liquid separation is divided into multiple stages with progressively narrower passages. Liquid is extracted in stages rather than all at once, allowing the material to be progressively dewatered without excessive liquid remaining in roller porosities that would cause remoistening. Each stage handles a portion of the liquid extraction task.
Solution Approach 2:
The invention transitions from a single-dimension extraction approach to a multi-dimensional cascading structure with passages arranged in sequence. This dimensional change allows liquid to be extracted through multiple passages in series, reducing the liquid capacity needed in individual rollers and minimizing remoistening.
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 significantly improves drying rates, reduces remoistening, and maintains fiber integrity for litter use, achieving up to 37% dry matter with reduced energy consumption and minimal mechanical issues, while allowing for more efficient water extraction and longer fiber preservation.
Implementation Method 1
The upper wringing component and the lower draining component are positioned with respect to another so as to define a passage through which mixture material to be processed is channeled and pressed, in order to extract liquid material therefrom
Implementation Method 2
The phenomenon of surface tension in the liquids causes the liquid extracted and going through the porosities of the roller to not be entirely extracted since an amount of water remains within the porosities of the roller
Implementation Method 3
The phenomenon of surface tension in the liquids causes the liquid extracted and going through the porosities of the roller to not be entirely extracted since an amount of water remains within the porosities of the roller

AI summary
A liquid separating device (1) for processing a mixture material (3) containing both solid and liquid materials (3a, 3b), in order to separate liquid material (3b) from the solid material (3a), the liquid separating device (1) includes a support frame (5), a series of liquid separation assemblies (7a, 7b) and a corresponding guiding assembly ( 19) between each pair of liquid separation assemblies (7). The liquid separation assemblies (7) are disposed about the support frame (5) in a cascading configuration, and the passage (13) of each liquid separation assembly (7) is narrower in width than the passage of a preceding liquid separation assembly (7) so that each subsequent liquid separation assembly (7b) is enabled to extract more liquid material via an increased wringing pressure resulting from a thickening of the remaining mixture material (3) to be processed and the narrower subsequent passage (13b) through which it is channeled and pressed.
