Waste Liquid Filtration With Bubble Water Seal Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing waste liquid treating apparatuses face issues with bubble leakage when surfactants are used in processing water, leading to operational disruptions and inefficiencies in purifying and recirculating processing water.
Innovation Solution
A waste liquid treating apparatus is designed with a bubble water seal type pump and a sealing water reservoir tank to capture and recycle bubbles, integrating a temperature control unit and a spray water seal type pump to prevent external leakage and ensure continuous operation by reusing the treated water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surfactant is mixed into processing water to prevent deposition of cutting chips, then the processing water can effectively restrain deposition, but bubbles are generated in the waste liquid treating apparatus and may leak to the exterior
Solution Approach 1:
The patent extracts and removes bubbles from the processing water system using a bubble removal device. The device separates bubbles from the liquid phase and discharges them externally, preventing bubble accumulation and leakage while maintaining the surfactant's deposition prevention function.
Solution Approach 2:
The patent introduces a bubble removal device as an intermediary component between the processing water circulation system and the external environment. This device acts as a mediator that captures and removes bubbles before they can leak, while allowing the processed water to continue circulating with surfactant functionality intact.
2Productivity
If bubbles are generated in the waste liquid treating apparatus, then the apparatus cannot directly continue operation, but removing bubbles requires additional equipment and complexity
Solution Approach 1:
The bubble removal device is designed to automatically remove bubbles from the processing water without requiring manual intervention or complex control systems. The device self-regulates bubble removal through its structural design, maintaining continuous operation while adding minimal complexity to the overall system.
3Loss of substance
If pure water is continuously purified and recirculated, then water consumption is reduced, but the purification system becomes complex and energy-intensive
Solution Approach 1:
Instead of implementing a complete and complex purification system, the patent applies partial action by focusing only on bubble removal as the critical impurity. This selective approach reduces water consumption and maintains processing water quality without requiring energy-intensive full purification systems, achieving practical water recycling with minimal complexity.
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
The apparatus effectively prevents bubble leakage and ensures the continuous operation of the processing water circulation system by recycling and purifying the waste liquid, maintaining the quality of the processing water for reuse.
Implementation Method 1
a bubble water seal type pump that sucks at least bubbles generated in the waste liquid filter unit
Implementation Method 2
a waste liquid filter unit that filters the waste liquid in the waste liquid accommodating tank to purify the waste liquid into fresh water
Implementation Method 3
a temperature control unit that controls the pure water obtained by purifying the fresh water by the pure water producing unit, to a predetermined temperature

AI summary
A waste liquid treating apparatus includes a waste liquid accommodating unit for waste water discharged from a processing apparatus. A waste liquid filter unit filters the waste liquid in that tank to purify the waste liquid into fresh water. A fresh water reservoir tank reserves the fresh water obtained by filtering the waste liquid by the waste liquid filter unit. A pure water producing unit purifies the fresh water reserved in the fresh water reservoir tank into pure water, and a temperature control unit controls the pure water obtained by purifying the fresh water by the pure water purifying unit to a predetermined temperature. A bubble water seal type pump sucks at least bubbles generated in the waste liquid filter unit, and a sealing water reservoir tank reserves the bubbles sucked by the bubble water seal type pump as a waste liquid.
