Bin Washing System Solid-Liquid Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Trash receptacles are not typically cleaned inside during collection, leading to organic matter decomposition and foul odors, posing health hazards and unpleasant conditions.
Innovation Solution
A bin washing system comprising a first and second solid-liquid separating device, a pump, and an inlet structure, which recycles cleaning water by separating solids from wastewater, reducing pump damage and extending its service life, and includes a mobile configuration for ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pump is used to pump cleaning water through the solid-liquid separating device, then the cleaning process is effective, but the pump is damaged by particulates in the water
Solution Approach 1:
The patent applies preliminary action by placing the solid-liquid separating device in the water path before the pump. This separator removes particulates from the water in advance, so that when the pump operates, it receives only clean water without damage-causing particles. The separator is positioned to intercept and remove solids before they can reach and damage the pump mechanism.
2Productivity
If the pump receives water with particulates, then the cleaning process can proceed, but the pump suffers damage reducing its service life
Solution Approach 1:
The patent uses an intermediary approach by introducing a solid-liquid separating device as a mediator between the water source and the pump. This separator acts as a protective intermediary that allows water with particulates to reach the pump while preventing the particulates from causing damage. The separator mediates the interaction between contaminated water and the pump, enabling continuous operation without direct exposure of the pump to harmful particles.
3Ease of operation
If the bin washing system is made mobile, then ease of use is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the bin washing system with multi-functional capabilities that can be deployed in various locations. The mobile configuration allows the same core system to serve multiple purposes: washing bins in different locations, adapting to various bin types, and being transported easily. This multi-functionality justifies the mobile design despite increased complexity, as the system can be used anywhere without requiring permanent installation.

AI summary
Provided is an example of bin washing system. The bin washing system may include a first solid-liquid separating device, a second solid-liquid separating device, a pump, and an inlet structure. The first solid-liquid separating device may be configured to receive a first solid-liquid suspension having first solids and second solids, separate the first solids from the second solids, and dispatch a second solid-liquid suspension having the second solids. The second solid-liquid separating device may be configured to receive the second solid-liquid suspension, capture the second solids, and dispatch cleaned water. The pump may be configured to pump cleaning water to the first solid-liquid separating device. The inlet structure may be configured to receive waste water that includes the first and second solids. The bin washing system may be configured to combine the cleaning water pumped by the pump with the waste water to form the first solid-liquid suspension.
