Filter Cylinder Forcing Structure for Dust Collector Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter cylinder type dust collectors suffer from a lack of airtightness due to inclined rails and single-point locking, allowing dust and chips to pass through, which reduces the filtration efficiency and quality of air purification.
Innovation Solution
The forcing and fixing structure incorporates parallel setting racks, unequal diameter forcing rods with rotary handles, and assembling-and-disassembling plates to ensure tight fit of filter cylinders with the division plate, enhancing airtightness and assembly convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter cylinder assembling-and-disassembling mechanism is locked at only one place with the division plate, then the assembly and disassembly process is simple, but the filter cylinders cannot be tightly fitted with the division plate, resulting in poor airtightness
Solution Approach 1:
The locking mechanism is segmented into multiple locking points (first locking point and second locking point) distributed at different locations between the filter cylinder assembling-and-disassembling mechanism and the division plate. This segmentation allows the mechanism to be locked at multiple positions simultaneously, ensuring tight fitting and good airtightness while maintaining ease of operation through the modular locking structure.
2Ease of manufacture
If inclined rails are used for the filter cylinder assembling-and-disassembling mechanism, then the assembly process is simplified, but the filter cylinders cannot be forced to tight fit with the division plate, creating gaps that reduce filtration efficiency
Solution Approach 1:
The forcing rods are designed with forcing portions that preliminarily apply forcing action to the filter cylinders before the final locking operation. This preliminary forcing action ensures the filter cylinders are pre-positioned and tightly fitted against the division plate, eliminating gaps and ensuring precise fitting while maintaining the simplicity of the inclined rail assembly structure.
3Device complexity
If a single locking point is used between the assembling-and-disassembling mechanism and the division plate, then the device complexity is reduced, but the airtightness and filtration quality deteriorate due to gaps formed
Solution Approach 1:
The locking mechanism is divided into multiple independent locking points (first locking point and second locking point) positioned at different locations. This segmentation increases the number of contact and locking points between the assembling-and-disassembling mechanism and the division plate, ensuring comprehensive sealing and preventing dust leakage without significantly increasing device complexity.
Solution Approach 2:
The multiple locking points and forcing actions are merged into a coordinated operation where the forcing rods and locking structure work together as an integrated system. This merging ensures that the filter cylinders are simultaneously forced and locked at multiple positions, achieving effective sealing and preventing dust leakage while maintaining operational simplicity.
