Disposal Bag Punching Device for Vacuum Pressure Equalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction-grade vacuuming devices face issues with disposal bags being sucked into the turbine, leading to impaired suction and the need for expensive special bags to prevent this, which increases operational costs.
Innovation Solution
A device, referred to as a punching device, is used to introduce openings into standard disposal bags when the vacuuming device is closed, allowing pressure equalization between the bag and the collecting tank, thereby preventing the bag from being sucked by the turbine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standard disposal bags are used without pre-punched openings, then the vacuuming device can operate with negative pressure to suck dust, but the disposal bag moves or is pulled in the direction of the turbine, impairing the suction process
Solution Approach 1:
The punching device performs preliminary action by creating openings in the disposal bag before the vacuuming operation begins. The punch and die are positioned in advance, and when the suction head is connected to the collecting tank, the punch automatically creates openings in the bag, allowing pressure equalization to occur before the negative pressure suction starts, thus preventing the bag from being pulled into the turbine
Solution Approach 2:
The punching device acts as an intermediary mechanism between the suction head and the disposal bag. It mediates the interaction by creating a controlled pressure equalization path through the openings, allowing the negative pressure to be balanced without directly affecting the bag's position, thus resolving the conflict between maintaining suction pressure and preventing bag movement
2Reliability
If expensive special disposal bags with pre-punched openings are used, then the disposal bag remains stationary and suction is maintained, but the operational and consumption costs increase significantly
Solution Approach 1:
The invention enables the use of cheap standard disposal bags by providing a punching device that creates the necessary openings during operation. This replaces the need for expensive pre-punched special bags, allowing cost-effective standard bags to be used while maintaining the same functional reliability through on-demand opening creation
Solution Approach 2:
The punching device enables the disposal bag system to be self-sufficient by automatically creating the necessary openings when needed. The system serves itself by using the existing mechanical connection between the suction head and collecting tank to activate the punching mechanism, eliminating the need for pre-manufactured special bags and reducing operational costs
3Object-affected harmful factors
If the disposal bag is hermetically sealed in the collecting tank, then the dust medium is contained and protected, but the negative pressure causes the bag to be pulled toward the turbine
Solution Approach 1:
The punching device applies local quality by creating specific localized openings in the disposal bag at predetermined positions. These localized openings allow pressure equalization only in specific areas, maintaining dust containment in the overall sealed structure while providing local pressure relief to prevent bag movement toward the turbine
