Solution Overview
Problem
Current solid-liquid separators for sewage, such as those using a wire ring with guide wires, face issues like complex installation, frequent maintenance, and inefficiencies due to wire corrosion and paper clogging, which hinder effective separation of solids and liquids.
Innovation Solution
A solid-liquid separator with a hollow structure featuring a curved-funnel-shaped inner separator surface and a frustoconically-shaped inner liquid guide surface, eliminating the need for guiding elements by utilizing geometric configurations to separate solids and liquids based on their differences in momentum, with a conduit connecting the separator and collector portions to ensure efficient separation and collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire ring with guide wires is used to separate solids and liquid, then separation function is achieved, but installation complexity increases and maintenance frequency increases
Solution Approach 1:
The patent removes the wire ring and guide wires from the separator system entirely. Instead, it uses a smoothly curved inner separator surface that guides solids and liquids through geometric design alone, eliminating the need for separate guiding elements and their associated installation and maintenance issues.
Solution Approach 2:
The patent employs a curved inner separator surface with specific geometric curvature to guide the flow of solid-liquid mixture. The curved surface naturally directs solids toward the solids outlet and liquid toward the liquid outlet without requiring additional guiding structures, simplifying the overall device design.
2Reliability
If guide wires are used to guide solids, then separation is achieved, but corrosion and clogging occur requiring frequent maintenance
Solution Approach 1:
The patent eliminates the wire ring and guide wires that are susceptible to corrosion and clogging. The separation function is achieved through the geometric design of the hollow structure's inner surfaces, which are not subject to the same degradation mechanisms as metal guide wires.
Solution Approach 2:
The patent changes the physical parameters of the guiding mechanism from thin metal wires to solid surfaces with specific geometric curvatures. This parameter change transforms the system from one using delicate guiding elements to one using robust geometric forms that resist corrosion and clogging.
3Productivity
If liquid flows along guide wires, then liquid is collected, but re-mixing with solids occurs reducing separation efficiency
Solution Approach 1:
The patent segments the hollow structure into distinct functional zones: a separator portion with a curved inner separator surface for initial separation, and a collector portion with a liquid guide surface for liquid collection. This segmentation prevents re-mixing by maintaining separate flow paths for solids and liquid throughout the structure.
Solution Approach 2:
The patent uses three-dimensional geometric surfaces to guide flow in multiple directions simultaneously. The curved inner separator surface and frustoconical liquid guide surface create spatial separation of flow paths, directing solids and liquid into different dimensional zones that prevent re-mixing.
4Reliability
If wire ring is used for separation, then solids and liquid are separated, but installation must be precise without error
Solution Approach 1:
The patent removes the wire ring assembly that requires precise installation. The separation function is achieved through the inherent geometry of the hollow structure itself, which does not require alignment or precise positioning during installation.
Solution Approach 2:
The patent merges the guiding function previously performed by separate wire ring components into the integrated hollow structure. The inner separator surface and liquid guide surface work together as a unified geometric system, eliminating the need for separate installation steps and precision alignment.

AI summary
A solid-liquid separator including a hollow structure. The hollow structure may include a separator portion having a solid-liquid-mixture inlet and a curved-funnel-shaped inner separator surface. The hollow structure may further include a collector portion having a frustoconically-shaped inner liquid guide surface. The separator portion and the collector portion may be disposed such that a spout of the curved-funnel-shaped inner separator surface and a narrower end of the frustoconically-shaped inner liquid guide surface may be directed towards each other.
