Conveyor-Belt Filter Chain Tension Measurement for Wear Control

Solution Overview

Problem

Conventional conveyor-belt filter devices experience excessive wear due to improper tensioning of the chain, which is difficult to visually assess and prone to fluctuation, leading to increased mechanical stress and potential damage.

Innovation Solution

Incorporation of a measuring mechanism with a gauge and measuring unit to accurately measure tension and slack of the chain, allowing controlled adjustment to minimize wear.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the chain tension is set too low or slack is set too large, then the chain runs smoothly, but the filter elements drag across the bottom of the channel causing increased wear and potential destruction

Engineering Contradiction:

Improvechain operation smoothnessVSAvoidfilter element durability

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The patent replaces subjective mechanical judgment with objective measurement technology. A measuring mechanism with sensor detects chain tension forces and converts them into measurable electrical signals, allowing precise quantification of tension status. This substitution of mechanical sense judgment with electronic measurement enables accurate monitoring of chain tension to prevent both excessive slack and over-tensioning.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements a feedback control system where the measuring mechanism continuously monitors chain tension and provides real-time information about tension status. The sensor detects tension variations and feeds this information back to the control system, which can then adjust the tensioning mechanism to maintain optimal tension levels, preventing the harmful effects of both insufficient and excessive tension.

Inventive Principle:

Principle #23Feedback
