Extruder Cutting Apparatus With Upward Cyclonic Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting devices for extruders require pipes or hoses below the cutting tool for material discharge, complicating cleaning and causing material deformation due to vertical air flow, which affects product quality.
Innovation Solution
The cutting apparatus features inlet and outlet pipes that open into the housing from above and extend upwards, creating a cyclonic flow to gently discharge material, allowing hoses and pipes to be positioned above the device for easy cleaning and reducing material impact on housing walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pipes or hoses are arranged below the cutting tool for material discharge, then material can be collected and conveyed, but cleaning of the building becomes complicated
Solution Approach 1:
The patent inverts the conventional arrangement by positioning inlet and outlet pipes above the cutting tool instead of below it. The pipes extend upwards from the housing, allowing material discharge through the top rather than the bottom, thereby eliminating the need for complex below-floor piping and enabling easy cleaning of the building interior.
2Productivity
If air stream flows vertically downward through the cutting device, then material can be discharged, but material deformation occurs due to impact against housing walls
Solution Approach 1:
The patent inverts the conventional vertical downward air flow by implementing upward flowing air streams through inlet and outlet pipes positioned above the cutting tool. This reversal changes the discharge mechanism from gravity-assisted downward flow to upward cyclonic flow, eliminating material impact against the housing bottom wall and preserving product quality.
Solution Approach 2:
The patent employs pneumatic principles by using pressurized air streams flowing through the inlet and outlet pipes to generate cyclonic motion within the cutting device. The upward flowing air creates a vortex that gently transports shredded material outward and upward, replacing the harmful vertical downward impact flow with a gentle rotational discharge mechanism.
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
This design facilitates easy cleaning, enhances product quality by minimizing material deformation, and improves discharge efficiency through a cyclonic flow.
Implementation Method 1
the inlet pipe and the outlet pipe are arranged in such a way that a passing air stream creates a cyclone flow within the cutting device
Implementation Method 2
an air stream is usually passed through the cutting device, which discharges the material through an outlet opening located at the bottom of the cutting device with the aid of gravity
