Cyclone Filter Displacement for Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air separation devices using cyclone separators face issues with environmental pollution due to the release of suspended matter when replacing filters and emptying collection containers, as they require opening the system, allowing contaminants to escape.
Innovation Solution
The design incorporates a system where the filter is not pulled out but instead falls into the collection container, with seals preventing contamination, and the collection bag is sealed and removed without exposing the cyclone separator to the environment, ensuring containment of suspended matter during filter changes and emptying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter is pulled out of the discharge pipe to replace it, then the filter can be replaced, but suspended matter escapes into the environment
Solution Approach 1:
The collection bag is inserted into the collection container, and the filter is inserted into the discharge pipe which protrudes into the separating container. This nested arrangement allows the filter to be pushed down into the collection container through the discharge pipe without removing it from the pipe, maintaining sealing while enabling replacement.
Solution Approach 2:
The discharge pipe acts as an intermediary channel that allows the filter to be pushed from the discharge pipe into the collection container. This intermediary structure enables the filter replacement process while maintaining the sealed environment, as the filter travels through the discharge pipe rather than being exposed to the external environment.
2Productivity
If the collection container is opened to empty suspended matter, then the container can be emptied, but suspended matter escapes into the environment
Solution Approach 1:
The collection bag is extracted from the collection container as a separate, self-contained unit. The collection bag can be pulled out through the opening in the collection container's bottom, allowing the suspended matter to be removed without opening the main cyclone separator housing, thus preventing contamination release.
Solution Approach 2:
The collection system is segmented into the collection container and the removable collection bag. This segmentation allows the collection bag to be independently removed and emptied, separating the waste removal process from the main separation device and maintaining the sealed environment of the cyclone separator.
3Device complexity
If the discharge pipe is fixed in the separating container, then the structure is simple, but filter replacement is difficult
Solution Approach 1:
The discharge pipe is made movable relative to the separating container through a guiding mechanism with slots and guide pins. This dynamic design allows the discharge pipe to be easily repositioned vertically, enabling simple filter replacement by pushing the filter down through the movable discharge pipe into the collection container.
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
This approach minimizes environmental pollution by keeping the cyclone separator's interior isolated from the environment during filter changes and emptying, effectively managing suspended matter disposal within the collection container.
Implementation Method 1
The suspended matter contained in the air is thrown against the wall of the separating tank by centrifugal force and slowed down so that it is released from the flow and falls down into a collecting tank
Implementation Method 2
The at least one filter is expediently held on an inside of the discharge pipe by means of a friction fit

AI summary
The invention relates to a device (10) for separating suspended particles from air with a cyclone separator (14) comprising a separation vessel (16), an air inlet (24) oriented tangentially with respect to a vertical longitudinal axis (22) at a distance from it and opening into the separation vessel (16), a collection vessel (20) into which the separation vessel (16) opens at its lower end (18), and a discharge pipe (28) opening into an air outlet (32), adjoining the separation vessel (16) at the top and communicating with it, and with at least one filter (34) arranged in the discharge pipe (28) for the suspended particles.According to the invention, the at least one filter (34) has a rigid, airtight outer shell (36) and a filter medium (40) arranged in the outer shell (36) at a distance from it, enclosing a central cavity (42), which communicates with the separator container (16) via an opening (48) at its first end face (50) facing the separator container (16) and is closed at its second end face (52) facing away from the separator container (16) by means of an airtight cover plate (54), that the at least one filter (34) is displaceable in the discharge pipe (28) in the direction of the separator container (16) and that the separator container (16) and the collection container (20) each have an inner diameter that is larger than the outer diameter of the at least one filter (34).
