Advantages and Application Directions of Explosion-proof Shot Blasting Machines
The explosion-proof shot blasting machine is a professional surface treatment equipment that is based on the ordinary shot blasting cleaning equipment and has a complete set of explosion-proof safety design for combustible metal dust and flammable/explosive gas working conditions. It can avoid explosion risks caused by friction sparks, electric sparks, static electricity, and dust accumulation, and complete tasks such as rust removal, oxide layer removal, welding slag removal, and surface strengthening for safe production.
Advantages of using explosion-proof shot blasting machines
1. Safe and explosion-proof, eliminating explosion hazards during shot blasting machine operation
A. Complete set of explosion-proof electrical components: explosion-proof motors, explosion-proof control cabinets, explosion-proof junction boxes, explosion-proof lighting, preventing ignition of dust clouds by electric sparks, meeting dust explosion safety standards requirements.
B. Explosion suppression and pressure relief protection: explosion-proof shot blasting machine dust collectors are equipped with spark catchers, flameless explosion relief devices, flame-retardant anti-static filter materials, dry powder fire extinguishing systems. Abnormal pressure is quickly released to prevent explosion propagation and extinguish open flames; a wet dust collector can also be selected to further reduce the risk of combustion and explosion.
C. Anti-static and anti-friction sparks: explosion-proof shot blasting machines have reliable grounding connections, eliminating static electricity in real time; key parts of the chamber use materials that do not produce sparks under impact and reduce the friction sparks from shot blasting; the chamber has no dead corners, reducing the accumulation of flammable/explosive dust.
D. Sealing and dust prevention: explosion-proof shot blasting machines have a sealed structure and negative pressure design, reducing the leakage of flammable/explosive dust and lowering the risk of explosion in the workshop environment.
2. Comparable to ordinary shot blasting machines in terms of process performance, while also considering production efficiency
High cleaning efficiency, recycling of shot blasting particles, capable of performing rust removal, oxide layer removal, burr removal, surface stress strengthening, and meeting the requirements for pre-treatment before coating and anodizing.
A wide range of models: tracked type, hook type, through type, suitable for small batch, medium and large-sized irregular parts, sheet metal and profiles for continuous operation, supporting customized explosion-proof grades and production capacity.
3. Compliant production, meeting safety supervision acceptance requirements
Compliant with GB3836 and GB24390 explosion-related norms, addressing safety rectification requirements for enterprises with explosive dust such as aluminum, magnesium, zinc, titanium, etc., and avoiding safety accident risks.
4. Reducing overall operational risks
Reducing personnel and equipment losses caused by dust explosion accidents;
Strong equipment stability, reducing downtime in high-risk conditions;
High filtration accuracy of the dust removal system, balancing environmental protection emission requirements.
Application directions of explosion-proof shot blasting machines
Applicable: Workpieces generated by aluminum, magnesium, zinc, titanium and other flammable/explosive metals during processing, and working conditions with flammable/explosive gases present.
1. Aluminum, magnesium, zinc metal industry (main scenarios)
Aluminum die-casting parts, magnesium alloy parts, zinc alloy die-casting parts: removing parting marks, oxide layers, and release agents, performing anodizing and pre-treatment before coating; aluminum alloy wheels, aluminum shells, lightweight alloy components, battery box components for new energy vehicles, cleaning and polishing.
2. Automotive parts manufacturing
Surface cleaning and strengthening pre-treatment for aluminum alloy transmission housings, engine aluminum components, aluminum magnesium alloy die-casting parts, lightweight alloy components.
3. Aerospace and precision manufacturing
Precise parts and components of titanium alloys, magnesium-aluminum alloys, sandblasting, surface strengthening; removing burrs from aluminum parts, meeting dual requirements of dust explosion prevention and surface quality.
4. Petrochemical, coal chemical equipment manufacturing
Petrochemical equipment components, explosion-proof valves, chemical storage tank accessories, rust removal, oxide layer removal, pre-treatment for anti-corrosion in environments with flammable/explosive gases or dust risks.
5. New energy industry
Surface pre-treatment for aluminum battery shells, energy storage cabinets, lightweight new energy structural components, suitable for explosion-proof workshops with aluminum dust requirements.
6. General high-risk conditions
1. Rust removal and deburring of aluminum, aluminum profiles, magnesium alloy hardware parts;
2. Cleaning of components from mining, explosion-proof equipment factories;
3. If the workshop itself is a dust explosion hazard area, even if processing carbon steel parts, the entire machine needs to undergo explosion-proof renovation projects.
Selection tips for explosion-proof shot blasting machines
1. When processing aluminum-magnesium-titanium alloy workpieces, it is strictly prohibited to use ordinary shot blasting machines directly. A complete set of explosion-proof configuration must be adopted.
2. Select the machine model based on the size and output of the workpiece: for small batches of workpieces, choose the explosion-proof crawler-type shot blasting machine; for medium and large irregular workpieces, choose the explosion-proof hook-type shot blasting machine; for large quantities of sheet metal and profiles, choose the explosion-proof through-type shot blasting machine.
3. Dry explosion-proof equipment is equipped with explosion-proof valves and isolation valves; for extremely risky working conditions, a wet explosion-proof dust removal system should be preferred.
