Bag Filter Cleaning Head with Internal Drive and Rotating Rotor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for bag filters expose the drive device to significant dust ingress during cleaning, leading to impaired function and potential failure, as dust is sucked into the housing and accumulates due to the cleaning process's design.
Innovation Solution
The drive device is integrated within the cleaning head and surrounded by an end cap, with a rotor forming the cleaning bore, allowing only the rotor to rotate and preventing exposure to dust, and the pressure medium hose is coupled to a pressure pipe for easy connection of mechanical components and control elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drive device is located inside the housing at the first end of the cleaning head, then the cleaning head can be connected to the pressure medium hose, but dust enters through the bearing and impairs the drive device function
Solution Approach 1:
The drive device is extracted from the housing and relocated to the cleaning head itself. This separation removes the drive device from the dust-prone environment inside the housing while maintaining its functional connection to the cleaning head, thus protecting it from dust impairment while preserving operational capability
Solution Approach 2:
The cleaning head serves as an intermediary carrier for the drive device. By placing the drive device in the cleaning head rather than in the housing, the system uses the cleaning head as a mediator to protect the drive device from dust while maintaining its functional connection to the pressure medium hose
2Manufacturing precision
If the entire cleaning head rotates to perform cleaning, then the cleaning bore can be positioned correctly, but rotating parts may collide with the support basket
Solution Approach 1:
The cleaning head is segmented into rotating and stationary parts. Only the rotor with the cleaning bore rotates, while the housing and other components remain stationary. This segmentation allows precise positioning of the cleaning bore while preventing collision with the support basket, as the rotating portion is limited to the rotor only
Solution Approach 2:
Instead of rotating the entire cleaning head housing, the invention inverts the approach by making only the internal rotor rotate while the housing remains stationary. This reversal of the rotation concept eliminates collision risks while maintaining cleaning bore positioning accuracy
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 configuration ensures the cleaning head does not require rotation, preventing dust exposure and maintaining the drive device's functionality, while allowing for effective cleaning by directing the cleaning jet radially onto the bag filter's inner wall, enhancing cleaning efficiency and reducing clogging.
Implementation Method 1
through the pressure medium exits a cleaning bore which can be rotated about a main axis of the cleaning head
