Demolition Tool Suction Device Segmented Retaining Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction devices for mining tools often clog due to larger pieces of mined material being sucked into the suction lines, leading to dust pollution and operational hindrances.
Innovation Solution
A suction device with a retaining element featuring defined suction openings that limit the size of material sucked in, preventing clogs and improving dust particle collection, utilizing a design with trapezoidal segments and a concave antechamber to guide airflow effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the suction device allows larger pieces of mined material to be sucked in, then the dust particle collection efficiency is improved, but the suction channels become clogged
Solution Approach 1:
The retaining element is divided into multiple segments that are arranged at distances from one another, creating defined suction openings. This segmentation allows the structure to filter material by size while maintaining open pathways for dust particles to pass through to the suction device.
Solution Approach 2:
The retaining element acts as an intermediary component between the suction openings and the suction channels. It mediates the suction process by allowing dust particles to pass while blocking larger pieces of mined material, preventing clogs in the suction channels.
2Stability of the object's composition
If the suction device uses an elastic section to maintain contact with the substrate, then the suction device remains stable during advanced excavation, but the suction device may kink without proper guidance
Solution Approach 1:
The feed-through opening for the tool is designed to form a guide for the suction device in advance, preventing kinking before it can occur. This preliminary structural guidance ensures that the elastic section maintains its shape and functionality throughout the excavation process.
Solution Approach 2:
The suction device incorporates an elastic section that can be reduced in its longitudinal extent, allowing it to flex and maintain contact with the substrate during advanced excavation while the feed-through opening provides structural guidance to prevent excessive deformation.
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
The solution effectively prevents suction line clogging and reduces dust pollution by controlling the size of material sucked in, ensuring efficient operation and maintaining clear airflow paths.
Implementation Method 1
dust particles produced are removed by means of the vacuum source
Implementation Method 2
the maximum size of the pieces of degraded material sucked in is limited, which prevents the suction channels from becoming clogged
