Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing stirring processing apparatuses face issues with throughput due to interference between suction and ejecting flows, particularly in highly viscous fluids, leading to cavitation and insufficient fluid introduction, which affects the processing efficiency regardless of fluid properties.
Innovation Solution
The apparatus incorporates a suppressing body between the suction and ejecting openings, designed to minimize interference by directing the suction flow smoothly into the stirring chamber, and utilizes a rotating screen to increase relative rotation speed without causing cavitation, enhancing shear strength and throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the rotating blade rotates at high speed to apply shear force to the fluid, then the processing efficiency is improved, but the suction flow and ejecting flow interfere with each other, causing cavitation and reducing throughput
Solution Approach 1:
A flow guide member is introduced as an intermediary component between the suction opening and ejecting opening. This flow guide member guides the suction flow to prevent it from interfering with the ejecting flow, thereby eliminating cavitation while maintaining high-speed rotation and processing efficiency
Solution Approach 2:
The flow guide member extends in the axial direction of the rotating blade, utilizing the third dimension (axial direction) to separate and guide the suction flow path. This spatial arrangement prevents the suction flow from directly interfering with the ejecting flow in the radial direction, resolving the flow interference problem
2Device complexity
If the suction opening and ejecting opening are disposed side by side to simplify structure, then the device complexity is reduced, but flow interference occurs between suction and ejecting flows
Solution Approach 1:
The flow guide member serves as a mediator that enables the side-by-side configuration of suction and ejecting openings to function properly. By guiding the suction flow along the periphery of the rotating blade, it prevents interference with the ejecting flow, allowing the simple side-by-side structure to achieve both structural simplicity and high throughput

AI summary
The present invention has an object to provide a stirring processing apparatus and a processing method to realize excellent processing of a fluid regardless of the properties of the fluid. The stirring processing apparatus is provided with the stirring blade 22 and the stirring chamber 18 provided with the screen 23, wherein the apparatus performs, under a state in which the stirring chamber 18 is disposed in a fluid to be processed, a process of applying a shear force to the fluid by a relative rotation between the screen 23 and the stirring blade 22. The stirring chamber 18 is provided with the suction opening 24 to suck the fluid from outside to inside and the ejecting opening 25 to eject the fluid from inside to outside; these openings being disposed above and below. The suppressing body 31 to control a flow of the fluid is disposed between the suction opening 24 and the ejecting opening 25. The suppressing body 31 is, for example, in the form of a cylinder, and is interposed between the suction flow 26 and the ejecting flow 27, thereby suppressing interference between the two flows.
