Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screening devices fail to adequately separate contaminants and aquatic animals from wastewater, risking contamination of aquatic animal channels and potential injury to the animals, and often require additional means to prevent contaminants from entering the animal channel.
Innovation Solution
A screening device with a circulating endless screening belt and dual collecting devices for contaminants and aquatic animals, utilizing upper and lower deflections to separate and collect materials efficiently, allowing for a compact design with minimal chamber opening and reduced fall height for aquatic animals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single outflow channel is used for both contaminants and aquatic animals, then the device structure is simplified, but contaminants can easily enter the outflow channel with aquatic animals and additional means are required to prevent this
Solution Approach 1:
The patent divides the outflow system into two separate channels: a first outflow channel for contaminants and a second outflow channel for aquatic animals. This segmentation ensures complete separation of the two streams, preventing contaminants from entering the aquatic animal channel while maintaining a relatively simple overall device structure.
2Area of stationary object
If the chamber opening is reduced to minimize device size, then the device becomes more compact, but it becomes difficult to ensure adequate separation and guidance of aquatic animals into the outflow channel
Solution Approach 1:
The patent utilizes the vertical dimension by arranging the first and second outflow channels one above the other or in overlapping positions. This three-dimensional arrangement allows adequate separation and guidance of aquatic animals even with a minimal horizontal chamber opening, effectively solving the space constraint problem.
3Reliability
If aquatic animals are conveyed over a long distance to the outflow channel, then separation is more thorough, but the fall height increases and aquatic animals may be injured
Solution Approach 1:
The patent introduces a guide unit as an intermediary structure that actively directs aquatic animals into the second outflow channel. This guide unit prevents aquatic animals from falling long distances by providing a controlled path, thereby maintaining thorough separation while preventing injury through the mediating guidance function.

Implementation Method 1
The screening device (1) comprises a plurality of screening elements (5) arranged in a row along a direction of movement (6), forming a circulating endless screening belt (7)... During proper use of the screening device (1), the wastewater (4) flows through the screening elements (5), retaining contaminants and aquatic organisms.
Implementation Method 2
The circulating movement of the endless screening belt along the direction of movement conveys the contaminants and aquatic organisms upward.
