Long Part Separator with Transverse Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for separating long parts from bulk materials are inefficient and prone to jamming, as they rely on non-selective separation techniques and additional mechanical devices, which are cumbersome and often fail to distinguish between long and compact parts effectively.
Innovation Solution
A device comprising a conveying device and a rake with interstices of varying dimensions, combined with a deflection device that aligns long parts transversely to the conveying direction, allowing them to slide over the rake webs while compact parts fall through, thereby separating long and compact parts without blockages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screens or vibratory conveyors are used to separate long particles, then separation of elongated particles is achieved, but long particles become jammed in the passages for fine particles
Solution Approach 1:
The deflecting device performs preliminary action by aligning long particles at an angle of 45° to 90° to the first direction before they reach the screen. This preliminary orientation prevents long particles from entering the screen passages in a jamming position, allowing them to be separated as coarse material without blocking the fine particle passages.
2Reliability
If brushes are used to comb elongated particles off the conveying device, then long particles are removed, but the separation is not selective and additional mechanical devices are required
Solution Approach 1:
The invention extracts the essential function of long particle separation from complex mechanical devices like brushes. By using a deflecting device that simply changes the orientation of long particles at 45° to 90°, the system achieves selective separation without requiring additional driven mechanical components, reducing device complexity while maintaining reliability.
3Productivity
If oscillating conveying systems with finger screens are used, then bulk material is conveyed and screened, but long pieces dip into the screen upon being dropped and fall through it
Solution Approach 1:
The deflecting device performs preliminary action by orienting long particles at an angle of 45° to 90° to the first direction before they reach the screen. This preliminary orientation ensures that when bulk material is conveyed and dropped, long particles approach the screen at an angle that prevents them from dipping into and falling through the screen openings, maintaining separation accuracy while preserving bulk material processing productivity.

AI summary
Device and method for separating elongated parts (long parts) from bulk materials. The device comprises the following elements: a conveying device (1), a deflecting device (2), and a screen with ridges (4) oriented longitudinally to the conveying direction. According to the method, the bulk material is transported on the conveying device (1), and then long parts (10) are aligned transversely to the conveying direction by means of a deflecting device (2). After passing the deflecting device (2), the transversely oriented long parts are transferred to the screen (4) and discharged as coarse material (7). Compact parts (11) fall through this screen and thus become part of the fine material (6).
