Vibration Sifter Suction Nozzle Layout for On-Sifter Powder Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration sifter devices do not effectively collect on-sifter powder, which can lead to clogging, despite methods to suppress clogging such as brushing or blowing off the powder, and there is a need for a device that can regularly collect this powder.
Innovation Solution
A collection device for vibration sifters that includes a hollow shaft with nozzles and suction ports, controlled by an elevation and rotation unit, to systematically collect on-sifter powder by moving and rotating the shaft and nozzles to ensure complete suction of powder from the sifter surface and inner barrel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brushing or blowing off the sifter surface is used to suppress clogging, then clogging is suppressed, but collection of the on-sifter powder is not accomplished
Solution Approach 1:
The patent combines the clogging suppression function (brushing/blowing) with the powder collection function (suction) into a single integrated system. The suction unit is positioned to work in conjunction with the cleaning mechanisms, allowing simultaneous removal of powder from the sifter surface and collection of the removed powder, thereby resolving the contradiction between suppressing clogging and achieving powder collection
Solution Approach 2:
The patent introduces a suction unit as an intermediary mechanism that captures the on-sifter powder after it has been loosened by brushing or blown off by air. This intermediary suction function enables the system to both suppress clogging (by removing powder from the sifter surface) and collect the powder (by directing it into a collection container), thus resolving the contradiction
2Productivity
If a collection device is added to the vibration sifter, then powder collection is achieved, but device complexity increases
Solution Approach 1:
The collection device is designed with multi-functionality: the suction unit serves both to collect powder and to prevent clogging, the container serves as both collection vessel and temporary storage, and the positioning mechanism allows the same structure to adapt to different sifter configurations. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while achieving powder collection
Solution Approach 2:
The patent employs adjustable parameters in the collection device design, such as the position of the suction unit, the size and shape of the container, and the airflow characteristics. These adjustable parameters allow the device to be optimized for different application scenarios without requiring completely different structural designs, thus achieving powder collection while controlling device complexity
