Sandblasting Gun Sand Source Selecting Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Typical sandblasting guns have a fixed sandbox that cannot easily increase sand supply, making them inadequate for larger metal workpieces and inefficient for smaller ones.
Innovation Solution
A sand source selecting structure with two sub-channels and control valves allows for selectable sand supply sources, enabling the gun to use either the sandbox or an external sand pile, allowing for adjustable sand flow based on the size of the workpiece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed sandbox is used in the sandblasting gun, then the structure is simple, but the sand supply amount cannot be adjusted for different sized workpieces
Solution Approach 1:
The sand supply system is segmented into multiple independent channels: a first sub-channel connecting to a sandbox and a second sub-channel connecting to an external sand pile. Each channel can be independently controlled by its own control valve, allowing selective activation based on workpiece size and sand consumption requirements.
Solution Approach 2:
The sandblasting gun is designed with multi-functionality by incorporating both a built-in sandbox and an external sand pile connection capability. The system can universally handle different sand supply scenarios (small workpieces using sandbox, large workpieces using external sand pile) through a unified dual-channel architecture with selective valve control.
2Quantity of substance
If a sandbox with fixed sand amount is used, then the device structure is simple, but it cannot meet the sand supply needs of larger metal workpieces
Solution Approach 1:
The sand supply system transitions from a static fixed sandbox to a dynamic configurable system. The control valves enable real-time switching between sandbox and external sand pile sources, and the system can dynamically adjust sand supply quantity by selecting appropriate sources based on workpiece size and treatment requirements.
Solution Approach 2:
Control valves serve as intermediaries between the sand sources (sandbox and external sand pile) and the sandblasting channel. These intermediary components enable easy selection and switching of sand sources without requiring complex manual intervention or system reconfiguration.
3Productivity
If the sandbox cannot increase sand amount easily, then the structure remains simple, but productivity decreases for larger workpieces
Solution Approach 1:
The sand supply system is segmented into multiple independent channels: a first sub-channel connecting to a sandbox and a second sub-channel connecting to an external sand pile. Each channel can be independently controlled by its own control valve, allowing selective activation based on workpiece size and sand consumption requirements.
Solution Approach 2:
The system prepares multiple sand supply sources in advance (sandbox and external sand pile) so that when a large workpiece requires extensive sandblasting, the operator can pre-select the external sand pile source through the control valve, ensuring continuous high-volume sand supply without interruption to productivity.

Function Achieved in This Case
This structure allows for flexible sand supply, optimizing sand usage for both larger and smaller metal workpieces by enabling the selection of sand sources, improving efficiency and adaptability in surface treatment processes.
Implementation Method 1
a first control valve installed in the first sub-channel; and a second control valve installed in the second sub-channel
Data Source
AI summary
A sand source selecting structure for a sandblasting gun has a main body; a channel provided in the main body, for passing pressurized gas; at least two sub-channels provided in the main body respectively connected to the channel; a sandbox mounted on the main body connected to the channel through the first sub-channel; a first control valve installed in the first sub-channel; and a second control valve installed in the second sub-channel. Therefore, the combination of the first control valve with the second valve provides a selecting structure, which can offer different sand supply sources.
