Application Scenarios of Vacuum Sand Suction Machines
Vacuum sand suction machines (bulk material recovery machines, wind-powered sand suction machines) are mainly applied in the recovery of grinding materials after sandblasting/shot blasting operations and the sealed transportation of bulk granular materials. They are particularly typical in the fields of shipbuilding and marine engineering, steel structure anti-corrosion, and bulk material handling at docks.
1. Shipbuilding and marine engineering
This is the most classic application area of vacuum sand suction machines (bulk material recovery machines, wind-powered sand suction machines). After sandblasting and rust removal of the hull, vacuum sand suction machines are used to recover grinding materials such as steel sand and copper ore sand, while also removing oxide scales and dust. This includes cleaning of shipyard compartments, water storage tanks, and sand recovery in the sand blasting rooms of ship sections, suitable for complex working conditions inside the ship compartments.
2. Steel structures, petrochemical pipelines, and bridge engineering
At large-scale steel structures, elevated bridges, and sandblasting anti-corrosion construction sites, vacuum sand suction machines are used to recover scattered grinding materials and clean sand dust and rust. For outdoor or semi-outdoor operations where a fully enclosed sandblasting shed cannot be set up, negative pressure recovery can significantly reduce material spillage and surrounding dust pollution, while also reducing the cost of grinding material procurement.
3. Casting and industrial cleaning
Casting plants use them for sand recovery; in various industrial production processes, they are used for cleaning and pneumatic transportation of dust and granular materials. Additionally, they are also applied in large-scale sandblasting sites in petrochemicals, mining machinery, and other industries.
3. Dock bulk material handling
Vacuum sand suction machines (bulk material recovery machines, wind-powered sand suction machines) are particularly suitable for the loading and unloading of sand from ships and vehicles at docks. The advantage lies in their ability to perform long-distance and small-diameter pneumatic transportation with high concentration. This scenario utilizes their negative pressure pneumatic transportation capability rather than the sandblasting recovery function.
Key Points for Scenario Adaptation
When choosing, it is necessary to distinguish the focus of requirements: in the grinding material recovery scenario, attention is paid to recovery efficiency (tons/hour) and grinding material breakage rate; in the bulk material handling/cleaning scenario, more emphasis is placed on transportation distance and the ability to maintain vacuum.
Environmental and Cleanliness of Vacuum Sand Suction Machines (Bulk Material Recovery Machines, Wind-Powered Sand Suction Machines)
Zero dust emission outside: The equipment operates under negative pressure, and dust will not leak out. Combined with efficient dust removal filters, the exhaust dust content can be controlled at ≤20 mg/m³, meeting strict emission requirements.
Improvement of working environment: Compared to manual sand cleaning or positive pressure blowing, it reduces the harm of dust to the health of operators and the surrounding environment from the source.
