Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fluid processing apparatuses face challenges in achieving uniform mixing and reaction between processing surfaces due to pulsation and pressure changes caused by the introduction of fluids, leading to difficulties in operation such as uniform mixing, reaction, and separation.
Innovation Solution
The apparatus incorporates a design with a pulsation-reducing depression and optimized depression arrangements on the processing surfaces to minimize pulsation effects, using a surface-approaching pressure mechanism and fluid pressure to stabilize the processing environment, allowing for continuous and uniform fluid introduction and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a first fluid is introduced between processing surfaces by rotating a processing member having a depression from a central side to an outer side (micro-pump effect), then the fluid can be introduced into the processing space, but pulsation occurs causing pressure change and flow disturbance that adversely affects uniform mixing and reaction
Solution Approach 1:
The processing member is divided into multiple independent depressions (first depression and second depression) that operate in sequence. The first depression introduces the first fluid while the second depression introduces the second fluid, segmenting the fluid introduction process to reduce pulsation and improve mixing uniformity.
Solution Approach 2:
A buffer chamber is introduced as an intermediary element between the fluid source and the processing space. This buffer chamber absorbs pressure fluctuations and pulsation from the rotating depressions, providing a more stable flow to the processing area and improving mixing uniformity.
2Use of energy by stationary object
If the processing member rotates to introduce fluid, then continuous fluid supply is achieved, but pressure change and flow disturbance occur near the opening where the second fluid is introduced
Solution Approach 1:
The buffer chamber serves as a mediator that decouples the rotating processing member from the stationary fluid introduction opening. It absorbs the harmful pressure changes and flow disturbances generated by rotation, delivering a smoother flow to the processing space.
Solution Approach 2:
The buffer chamber provides beforehand cushioning by pre-absorbing pressure fluctuations before the fluid enters the processing space. This cushioning effect protects the mixing zone from adverse pressure changes and flow disturbances.

AI summary
In order to enable the more stable performance of uniform treatment such as reaction by reducing pulsation generated in a fluid introduced between treatment surfaces using a micropump effect, provided is a device for treating an object to be treated between treatment surfaces (1, 2) facing each other of treatment parts which can move close to and away from each other and at least one of which rotates relatively with respect to the other, and performing the treatment by introducing a fluid between the treatment surfaces using a micropump effect by a recessed section (13) formed in at least one of the treatment surfaces (1, 2) and mixing and stirring the fluid between the treatment surfaces. The micropump effect generates force in the direction in which the treatment surfaces (1, 2) move away from each other by the rotation of a treatment part (10) and the recessed section (13) formed in the treatment surface (1) to thereby produce the effect of introducing the fluid between the treatment surfaces (1, 2). The recessed section (13) is formed so as to extend in the circumferential direction and inward/outward direction of the treatment surface (1), and multiple recessed sections (13) are provided or an additional recessed section (α) different from the recessed sections (13) is formed in at least one of the treatment surfaces (1, 2).
