Coupled Suction Supply Channel Air Recirculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction devices for machining processes are energy-intensive and inefficient in particle removal, often requiring separate compressed air supplies for blasting and filtration, which increases energy consumption and operational costs.
Innovation Solution
A suction device with a coupled suction and supply channel system recirculates processed air for blasting, reducing the need for separate compressed air and utilizing a pre-separator for coarse filtration, allowing for energy savings and improved particle collection without the need for high-purity air filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If separate compressed air supply and fine filtration system are used for blasting and particle removal, then particle elimination effectiveness is improved, but energy consumption and system complexity increase
Solution Approach 1:
The patent merges the suction channel and supply channel into a coupled system where processed air from the suction channel is routed back to the supply channel for blasting. This integration eliminates the need for separate compressed air supply and fine filtration systems, reducing energy consumption while maintaining particle elimination effectiveness through the recirculation of cleaned air
Solution Approach 2:
The patent recovers processed air that has passed through the pre-separator and work area, routing it back through the supply channel for continued use in blasting. This recovery approach prevents waste of already-cleaned air and reduces the energy required for continuous particle removal, as the system reuses air that has already served its primary filtration function
2Quantity of substance
If fine filtration system is used for air treatment, then air purity is improved, but air resistance and system cost increase
Solution Approach 1:
The patent applies different filtration qualities to different locations in the system: a pre-separator is placed at the suction channel inlet to remove coarse particles, while the air is then used for blasting without requiring fine filtration. This local quality approach matches the filtration level to the specific needs of each system section, reducing air resistance and energy loss while maintaining sufficient air purity for the blasting function
Solution Approach 2:
The patent changes the purity parameter requirements for air used in different system functions. Air extracted through the suction channel is sufficiently cleaned by the pre-separator for its intended purpose of blasting, eliminating the need for additional fine filtration. This parameter adjustment reduces air resistance and energy consumption while maintaining adequate air quality for the specific application
3Use of energy by moving object
If air is recirculated through coupled suction and supply channels, then energy savings are achieved, but particle deposition risk increases
Solution Approach 1:
The patent establishes continuous air flow through the coupled suction and supply channels, with processed air being constantly recirculated through the work area. This continuous action prevents particle accumulation and deposition by maintaining constant air movement, while the pre-separator continuously removes coarse particles, thereby achieving energy savings without increasing particle deposition risk
Solution Approach 2:
The patent introduces the pre-separator as an intermediary component between the suction channel and the recirculation path. This intermediary device removes coarse particles from the air before it is recirculated through the supply channel, preventing particle deposition on workpieces while allowing the energy-efficient recirculation system to operate effectively

AI summary
An exhaust device (1, 20, 40) is proposed for exhausting particles (8, 29), such as chips and/or dust from the processing area during the machining of wood, fiber, or composite materials or plastics and/or during the dry processing of metal materials, comprising an exhaust channel (9, 27, 47, 56, 66) for exhausting air together with the chips and/or dust to be exhausted from the processing area. In order to be able to save energy and for a better detection/extraction of the chips/dust, a supply channel (17, 28, 46, 57, 65) is provided for supplying air into the processing area, and the exhaust channel and the supply channel are coupled to each other, such that at least a part of the air exhausted via the exhaust channel is guided into the supply channel for recirculation of the air into the processing area, and the supply channel is designed for this purpose, and a tool (5, 24, 45, 53, 64) and/or workpiece (7, 26, 41, 55, 67) is to be directly illuminated in the processing area (50).
