Surface Treatment Machine Abrasive Removal Blower
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface treatment machines face instability and residual abrasive issues when treating elongated workpieces like H steel, as abrasives tend to remain on the surface, especially when conveyed in certain positions, leading to inefficiencies and stability concerns.
Innovation Solution
A surface treatment machine equipped with conveying equipment, a blasting device, and a blower that blows gas downstream and above the workpiece to remove residual abrasives, along with a receptacle to collect them, and optional features like height sensors, lifting devices, and antiscattering equipment to enhance efficiency and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the H steel is conveyed in its H-like position for stable conveying, then conveying stability is improved, but abrasives remain on the upper surface
Solution Approach 1:
The patent extracts and removes the harmful element (residual abrasives) from the workpiece surface using a blower device that blows air to detach and remove abrasives from the upper surface of the H steel, allowing the workpiece to be conveyed in the stable H-like position without contamination
Solution Approach 2:
The patent introduces an intermediary substance (air flow from the blower) to mediate between the blasting process and the conveying process, using the air flow to remove abrasives and enable stable conveying in the H-like position
2Object-generated harmful factors
If the H steel is conveyed in its I-like position to prevent abrasive residue, then residual abrasives are reduced, but conveying stability deteriorates
Solution Approach 1:
The patent introduces an intermediary substance (air flow from the blower) to mediate between the blasting process and the conveying process, using the air flow to remove abrasives and enable stable conveying in the H-like position
3Object-generated harmful factors
If manual labor or contact-based removal methods are used to remove abrasives, then abrasive removal is achieved, but productivity decreases and device complexity increases
Solution Approach 1:
The patent replaces manual labor and contact-based mechanical removal methods with a pneumatic system (blower device) that uses air flow to remove abrasives, achieving automated non-contact removal that maintains high productivity
Solution Approach 2:
The blower device enables the workpiece to self-clean during the conveying process, with the air flow automatically removing abrasives without requiring additional manual intervention or complex mechanical removal systems
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
Effectively prevents or inhibits residual abrasives on the workpiece, improving stability and efficiency by ensuring complete removal without manual labor or contact-based removal methods, and allows for the reuse of abrasives through a circulating mechanism.
Implementation Method 1
the blower blows the gas from above the conveying path to the upper surface of the workpiece such that the abrasives on the workpiece are blown off and removed therefrom
Implementation Method 2
the blasting device then projects the abrasives to the conveying workpiece such that it is surface treated

AI summary
Disclosed herein is a surface treatment machine that enables the inhibition or reduction of residual abrasives that remain on a workpiece that has been surface treated. An H steel (a workpiece to be treated) 12 is conveyed by means of a conveying device 20. Blasting devices 24A, 24B are then projected abrasives on to the conveying H steel such that it is surface treated. In the downstream of the blasting devices 24A, 24B along the conveying direction, a blowing port 30A of an air blower 30 is located above a conveying path to blow gas to the upper surface 112A of the H steel 12 such that the abrasives on the H steel 12 are blown off and removed therefrom.
