Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rock-drilling dust collection systems are inefficient due to slow operation of discharging devices, leading to health hazards from dust dispersion during rock drilling.
Innovation Solution
A method and apparatus where rock material is dosed in batches into a closable compression space using a displacement feeder, compressing the material into a smaller volume before discharge, allowing for simultaneous dosing and compression, and optionally incorporating a binder for enhanced compaction and dust control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rock material is removed from the dust separator with conventional discharging devices, then dust can be collected and separated, but the operation is slow and dust disperses into the environment
Solution Approach 1:
The invention changes the physical state of rock material from loose to compacted by applying compression force. The discharging device compresses the rock material into a compacted form, which prevents dust dispersion and simultaneously enables faster removal, thus improving productivity while eliminating harmful dust dispersion.
2Object-affected harmful factors
If rock material is compacted into a solid cake, then dust dispersion is minimized, but additional compression space and time are required
Solution Approach 1:
The invention merges the dust separator and discharging device into an integrated system where the compression space is incorporated within or directly connected to the dust separator. This combination eliminates the need for separate compression equipment, reducing overall device complexity while still achieving effective dust containment through compaction.
3Productivity
If rock material is dosed in batches with a displacement feeder, then compression can be performed effectively, but the dosing process becomes more complex
Solution Approach 1:
The displacement feeder is designed to perform multiple functions: it doses rock material in batches, transports it to the compression space, and facilitates compression through its reciprocating motion. This multi-functionality reduces the need for separate dosing and compression equipment, thereby reducing overall device complexity while maintaining high compression efficiency.

AI summary
The invention relates to a method for processing dust when breaking rock, to a dust separator, and further to a rock-drilling rig. Rock material and air sucked from a borehole (9) or some other operating location is separated from each other in the dust separator (14). The separated rock material (25) falls into a discharge part (14a) of the dust separator, from which it can be dosed in batches into a discharging device (16). The discharging device comprises a closed compression space (39) in which the rock material batch is compressed into a more compact state. This forms a solid matter cake (17) that is removed from the dust separator (14).
