Solution Overview
Problem
Conveyor belt filter devices require frequent adjustments to maintain optimal contact force and compensate for wear and elongation of the flexible drive, leading to increased maintenance efforts without ensuring operational reliability.
Innovation Solution
The scraper device is supported by a common carrier with a spring device, allowing simultaneous adjustment of the upper deflection device and support device, maintaining constant contact force and reducing the need for separate adjustments, with a tension spring design for easy force adjustment and compact layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the scraper device is adjusted to maintain optimal contact force, then cleaning effectiveness is improved, but maintenance effort increases due to frequent adjustments
Solution Approach 1:
The scraper device is designed to automatically adjust and maintain optimal contact force through the spring mechanism and common carrier arrangement. The system self-regulates the contact force between the scraper and filter belt, eliminating the need for frequent manual adjustments and reducing maintenance effort while ensuring consistent operational reliability
Solution Approach 2:
The scraper device incorporates a spring mechanism that allows dynamic adjustment of contact force. The spring enables the scraper to adapt to variations in filter belt tension and wear automatically, maintaining optimal cleaning effectiveness without requiring manual intervention, thus reducing maintenance frequency while preserving reliability
2Manufacturing precision
If the upper deflection device is adjusted to compensate for drive element elongation, then conveyor belt positioning is improved, but scraper device contact force consistency deteriorates
Solution Approach 1:
The support device for the scraper is integrated with the upper deflection device on a common carrier. This merging ensures that when the upper deflection device is adjusted to compensate for drive element elongation, the support device is adjusted simultaneously and equally, maintaining constant contact force between the scraper and filter belt while preserving accurate conveyor belt positioning
Solution Approach 2:
The common carrier acts as an intermediary structure that couples the upper deflection device and support device adjustments. This intermediary ensures that adjustments for drive element elongation are transmitted equally to both devices, maintaining both positioning accuracy and contact force consistency without requiring separate adjustment procedures
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 configuration minimizes necessary adjustments and maintains consistent contact force, reducing maintenance efforts and ensuring operational reliability by dynamically adjusting to changes in the drive elongation and wear, while preventing damage from larger objects.
Implementation Method 1
the support device has a spring device to generate a supporting force
Implementation Method 2
which ensures a rapid reduction of the contact gap
Implementation Method 3
it is particularly advantageous if the support device has a spring device to generate a supporting force, so that dynamic restoring forces are formed
Implementation Method 4
The rocker arm is mounted above the deflection shaft, so that reliable contact between the support device and the scraper device is ensured by gravity
