Screw Conveyor Guide Plate and Perforated Cover for Chip Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screw conveyors face blockages due to aluminum chips floating on cutting fluid, causing inefficiencies in chip discharge and fluid overflow.
Innovation Solution
A screw conveyor design featuring a guide plate and screw cover with fine holes to prevent chips from floating, ensuring chips are collected and discharged effectively, while allowing cutting fluid to pass through.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional screw conveyor uses a storage tank with an opening covered by perforated metal for collecting cutting fluid, then the cutting fluid can be collected and discharged, but aluminum chips float on the cutting fluid surface and block the opening
Solution Approach 1:
The storage tank is divided into a first storage tank for chips and a second storage tank for cutting fluid, with a partition wall between them. This segmentation prevents chips from mixing with cutting fluid and blocking the opening, while still allowing both to be collected and discharged effectively.
Solution Approach 2:
A screw conveyor is introduced as an intermediary device between the two storage tanks. The screw conveyor transfers chips from the first storage tank through the partition wall to the second storage tank, enabling chip discharge without requiring chips to pass through the opening that would otherwise be blocked.
2Productivity
If the screw conveyor stirs the cutting fluid to move chips, then chips are conveyed rearwards, but this stirring action causes light aluminum chips to float on the cutting fluid surface
Solution Approach 1:
By segmenting the storage tank into separate zones for chips and cutting fluid, the patent eliminates the interaction between screw stirring and chip floating. Chips are conveyed through the partition wall without being stirred in the cutting fluid, maintaining both conveyance efficiency and chip position stability.
3Quantity of substance
If the opening is covered with perforated metal to allow cutting fluid collection, then fluid can pass through, but chips accumulate and block the perforated metal
Solution Approach 1:
The partition wall creates separate storage zones, preventing chips from reaching the opening covered with perforated metal. Cutting fluid can still be collected through the opening while chips are contained in the first storage tank and discharged via the screw conveyor, eliminating chip accumulation on the opening.

AI summary
A screw conveyor that appropriately discharges chips inside cutting fluid includes: a main body in the form of a container provided with a storage tank; a screw rotatably assembled inside the storage tank; a discharge pipe formed at a rear side of the main body and connected to the storage tank; an inlet section configured to receive the chips and the cutting fluid into the storage tank at a front side; a guide plate configured to guide the chips and the cutting fluid to the screw; a screw cover provided with multiple fine holes configured to cover a space above the screw; and an opening formed in the storage tank at a position higher than the screw cover such that the cutting fluid enters inside the main body.
