With increasing environmental protection requirements and upgraded manufacturing standards, traditional open-loop sandblasting operations can no longer meet modern production needs. Qingdao Puhua Heavy Industry Machinery Co., Ltd., combining over twenty years of experience in surface treatment equipment manufacturing, has launched a fully automated recycling sandblasting booth system, providing the industry with a complete, efficient, and environmentally friendly solution.
The equipment adopts a fully enclosed structural design, integrating sandblasting, recycling, dust removal, and sorting processes within a standardized chamber. During operation, abrasive particles impact the workpiece surface through a high-pressure spray gun, carrying impurities into a recovery system. After multi-stage sorting, the clean abrasive particles are returned to the sandblasting system for reuse. This closed-loop design achieves an abrasive utilization rate of over 95%.
The system is equipped with an industrial-grade PLC control center, which can preset various combinations of process parameters. After the operator selects the workpiece type via a touchscreen, the system automatically matches parameters such as sandblasting pressure, abrasive flow rate, and spray gun movement speed. The real-time monitoring system continuously records key data such as abrasive consumption and dust removal efficiency, enabling refined production management.
The dust removal system employs a three-stage filtration design: a primary cyclone separator removes large particles, a intermediate cartridge dust collector filters fine dust, and a final high-efficiency filter ensures emissions meet standards. Actual measurement data shows that the equipment's emission concentration is below 15 milligrams per cubic meter, fully meeting the requirements of the GB 16297 national standard.
Compared to traditional sandblasting equipment, this system improves abrasive circulation speed by 40% through optimized recovery pipeline design and the use of high-efficiency sorting technology. Combined with a frequency converter-controlled fan and intelligent pressure regulation device, overall energy consumption is reduced by approximately 30%. Annual operating costs per unit can be reduced by over 150,000 RMB.
Qingdao Puhua Heavy Industry offers modular designs, allowing customers to choose according to their production needs:
Standard Type: Suitable for processing conventional workpieces, equipped with 8-12 spray guns
Reinforced Type: For heavy-duty steel structures, equipped with a high-pressure sandblasting system
Customized Type: Customized chamber and recovery system designed according to specific process requirements
The sandblasting chamber body is welded from 6mm steel plates, with replaceable wear-resistant rubber linings inside. Key components feature double-thickness design to ensure equipment stability under continuous operation. All doors and windows employ multi-layer sealing structures to effectively prevent abrasive leakage.
In multiple large-scale engineering projects, the fully automated recycling sandblasting booth has demonstrated outstanding performance:
A shipbuilding company, after application, increased its section processing efficiency from 400 square meters per shift to 650 square meters.
An engineering machinery manufacturer, after use, reduced the processing time for individual structural components by 35%.
A bridge steel structure company reported that the pretreatment quality fully meets the requirements for heavy-duty anti-corrosion coating construction.
The equipment is particularly suitable for the following fields:
Shipbuilding and Repair: Surface treatment of hull sections, decks, and compartments
Energy Equipment: Anti-corrosion pretreatment of wind turbine towers, pressure vessels, and pipeline systems
Transportation: Surface treatment of bridge steel structures, railway vehicles, and containers
Heavy Machinery: Engineering Maintenance and Refurbishment of Equipment, Mining Machinery, and Port Machinery
Qingdao Puhua Heavy Industry has established a comprehensive service system:
* Installation and Commissioning Support: A professional engineering team provides on-site installation guidance to ensure equipment reaches optimal operating condition.
* Operation Training Service: A combination of theoretical instruction and practical training ensures operators fully master equipment operation skills.
* Regular Maintenance Plan: Personalized maintenance plans are developed, including replacement cycles for vulnerable parts and key system testing points.
* Rapid Response Mechanism: Twelve service centers nationwide ensure commonly used spare parts are delivered to the site within 24 hours.
The surface treatment industry is currently developing towards intelligent and green directions. Qingdao Puhua Heavy Industry's R&D team continuously upgrades its technology. The new generation of sandblasting booth systems will integrate IoT technology to achieve remote monitoring, intelligent diagnosis, and preventative maintenance. Simultaneously, specialized sandblasting processes adapted to special alloys, composite materials, and other new materials are being developed to provide customers with more comprehensive solutions.
Choosing the right sandblasting equipment directly affects product quality and production efficiency. Fully automatic recycling sandblasting booths not only meet current environmental protection requirements but also provide technical support for the long-term development of enterprises. Qingdao Puhua Heavy Industry will continue to uphold its commitment to technological innovation, continuously improving product performance and service systems to support the high-quality development of China's manufacturing industry.
