Wet Dust Collector Multi-Cyclone Water Separation for Vacuum Cleaners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wet type dust collecting apparatuses face limitations in dust separating efficiency and collection region due to the use of a single cyclone and a small centrifugal separating pipe diameter, which restricts the enhancement of dust separating efficiency and extends the dust collecting region.
Innovation Solution
The apparatus includes a first separating unit with a centrifugal separating pipe and a dust container, along with multiple second centrifugal separating units that filter dust from air by direct contact with water, using impellers and water overflow preventing ribs to enhance separation efficiency and prevent water overflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single cyclone is used for dust separation, then the device complexity is reduced, but the dust separating efficiency decreases
Solution Approach 1:
The dust separation system is divided into multiple cyclones (first cyclone and second cyclone) that operate in series. The first cyclone performs initial separation and the second cyclone performs further separation, thereby increasing overall dust separating efficiency while maintaining reasonable device complexity through modular segmentation
2Productivity
If the diameter of centrifugal separating pipe is reduced to increase water rotation speed, then dust separating efficiency increases, but the dust collecting region is limited
Solution Approach 1:
The centrifugal separation process is segmented into multiple stages with different pipe diameters. The first centrifugal separating pipe has a larger diameter for initial separation with broader collection region, while the second centrifugal separating pipe has a smaller diameter for enhanced water rotation speed and higher dust separating efficiency in the second stage
Solution Approach 2:
The system extends the dust collection capability from a single-dimensional approach to a multi-dimensional approach by using multiple cyclones arranged in series, where each cyclone handles a different portion of the dust separation process, thereby expanding the effective dust collecting region while maintaining high separation efficiency

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration increases dust separating efficiency by enhancing the contact area and time between air and water, minimizing water overflow, and effectively collecting dust in both the first and second centrifugal separating regions.
Implementation Method 1
a first separating unit configured to filter out and discharge dust by rotating air which is inlet via a first air inlet
Implementation Method 2
a plurality of a second centrifugal separating units configured to filter out dust from the air which is discharged from the first separating unit, and configured to eliminate dust from the inlet air via water which is filled inside of the second centrifugal separating units
Implementation Method 3
Air which is inlet to the second centrifugal separating units may be directly contacted to the water which is filled inside of the second centrifugal separating units and rotated so that dust in air is filtered out
