Solution Overview
Problem
Conventional cyclone separators have limited dust filter efficiency, requiring either increased chamber volume or complex multi-layered dust filter inner cylinders, which are bulky, difficult to maintain, and inadequate for industrial applications.
Innovation Solution
A multi-cyclonic dust filter device with a deflector component comprising first and second deflector tubes, where the first tube has dust filter holes and a deflector hood to redirect dust back into the collection chamber, forming multiple cyclones to enhance dust separation and filtration efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the volume of the chamber in the separation cylinder is increased to improve dust filter effect, then the dust filter efficiency is improved, but the overall volume of the cyclone separator becomes bulky
Solution Approach 1:
The invention divides the separation cylinder into multiple independent separation chambers (first separation chamber, second separation chamber, etc.), each capable of independent cyclone separation. This segmentation allows the total dust filter efficiency to be improved by adding more chambers rather than increasing the volume of a single chamber, thus avoiding the problem of bulky overall volume while achieving better dust filtration performance through parallel processing of multiple smaller chambers.
2Reliability
If a multi-layered dust filter inner cylinder is provided in the separation cylinder to improve dust filter effect, then the dust filter efficiency is improved, but the structure becomes more complicated and maintenance becomes difficult
Solution Approach 1:
Instead of adding complex multi-layered inner cylinders within a single chamber, the invention segments the system into multiple independent separation chambers arranged in parallel. Each chamber is a simple, self-contained unit that can be easily accessed and maintained. This approach achieves improved dust filter efficiency through increased total separation capacity rather than through complex internal structures, thereby maintaining simplicity and ease of maintenance.
3Reliability
If a multi-layered dust filter inner cylinder is implemented to improve dust filter effect, then the dust filter efficiency is improved, but the periodic replacement of the dust filter inner cylinder requires system shutdown
Solution Approach 1:
The invention divides the dust filtration system into multiple independent separation chambers, each with its own simple structure and dust collection capability. When maintenance is needed, only one chamber needs to be accessed and emptied at a time while other chambers continue to operate. This segmentation eliminates the need for complete system shutdown during maintenance, improving operational convenience while maintaining high dust filter efficiency through the parallel operation of multiple chambers.
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 multi-cyclonic design improves dust filter efficiency while maintaining a compact structure, simplifying maintenance and meeting industrial dust collection requirements.
Implementation Method 1
The centrifugal force is used to rotate the particles in a vortex flow at a high speed. The faster the rotation speed, the faster the centrifugal sedimentation speed the particles obtain, thereby achieving the object of separating the particles from the airflow.
Implementation Method 2
The cyclone separation actually belongs to a type of centrifugal sedimentation. The gas then forms a descending swirl along an inner wall of the separation cylinder 8, and finally due to a suction force provided to the suction duct 82, an ascending airflow is formed in the separation cylinder 8.
Implementation Method 3
The dust is unable to rise with the ascending airflow due to its own gravity, and sinks to the bottom of the separation cylinder 8, thereby generating a dust collecting effect.

AI summary
A multi-cyclonic dust filter device comprises a dust collection chamber for collecting dust, a cyclonic chamber providing a gas to-be-filtered out dust to enter and forming a first cyclone to enter into the dust collection chamber, and a deflector component disposed between the dust collection chamber and the cyclonic chamber; the deflector component comprises a first deflector tube for receiving the gas to-be-filtered out dust refluxed from the dust collection chamber and forming a second cyclone, and a second deflector tube disposed in a same axial direction as the first deflector tube and separately disposed by an airflow convergence interval, the first deflector tube is provided with at least one dust filter hole for discharging the dust in the second cyclone, and the second deflector tube combines the first cyclone and the second cyclone through the airflow convergence interval to form a third cyclone for discharging.
