Principle Introduction:
The interior of the sandblasting room forms an air flow layer from top to bottom due to wind force. Abrasive materials, compressed by air, are jetted onto the workpiece surface to remove chips. Some chip fragments turn into dust, which is carried down by the airflow and mixed with abrasive materials and rust debris. The mixture returns to the sorting system via a honeycomb back-sanding floor. After sorting, reusable sand is returned to the storage bin and automatically recycled in the sandblasting system as needed. Dust and impurities that cannot be reused are transported to a dust collector for fine filtration. The settled dust is then recycled, and the filtered gas is released into the atmosphere or reused in the sandblasting room. The entire process is enclosed, with no dust leakage, ensuring safety and environmental protection.
The complete set of mechanical recycling sandblasting room equipment consists of the sandblasting room body, lighting system, air-powered recovery floor, separator, sandblasting system, dust collector, fan, control system, workpiece conveying system, and operator protection system.
Mechanical Recirculating Sand Blasting Booth Features:
★ Eco-Friendly: Fans are powered electrically for clean, pollution-free operation; sandblasting is conducted in a sealed environment, and the sand is recycled through enclosed pipelines, ensuring no leakage of sand or dust to contaminate the surroundings; dust is filtered by a core filter dust collector, with the exhaust gas concentration meeting or exceeding national emission standards.
★Automatic Recycling: The system features an air-powered recycling floor for the automatic reuse of sand materials.
★Dual-purpose: The wind generated by the fan meets both the requirements for conveying sand materials and the system's dust removal needs.
★Automatic Sorting: The sorting unit utilizes the principles of aerodynamics to effectively segregate sand, impurities, and dust. Recyclable sand returns to the storage bin, while non-recyclable dust and impurities are transported to the dust collector for fine filtration.
★ Filter Core Dust Removal: The system employs filter core dust removal method, with high filtration efficiency.
★ Imported Filter Media: Made from imported long fibers, the filter cores offer a large filtering area, with each core having twice the filtering area of a standard filter core.
★Automatic Control: Automatic control is achievable for sand recycling, sorting, nozzle control, dust removal, and sand blasting pot operations. The system also features automatic alarm alerts for system failures.
High integration: The control system employs PLC + touch screen display, enabling both automatic operation mode and manual control mode.
★High-Efficiency Cleaning: Equipped with a high-pressure dual-cylinder continuous sandblasting machine, a single nozzle can clean up to 10 ~ 30 m2/h.
Compared to traditional shot blasting (bead) rooms, it boasts the following distinct features:
1. No need for deep excavation (excavation can be omitted), low infrastructure costs, and a short construction period.
2. Equipped with sand-suction floor, no need for traditional conveyors, belt conveyors, bucket elevators, etc. This avoids wear, clogging, and other issues caused by sand and dust during transportation and lifting processes, resulting in low failure rates and reduced maintenance workload.
3. Equipped with abrasive separator and sorting device, the abrasive is automatically recycled, improving utilization rate and sandblasting cleaning efficiency.
4. The abrasive recycling separator and dust removal share a single fan, achieving multi-functional use with one fan, saving 30% of energy compared to traditional sandblasting rooms.
5. The sandblasting system allows one sand pot to power multiple high-speed guns, each of which can be controlled independently. The sandblasting cleaning efficiency is high, and the working pressure can be infinitely adjusted.
6. Utilizes carbide-tough shot blasting nozzles with an average lifespan of 800-1000 hours.
7. The shot blasting room can utilize different materials and grain sizes of abrasive media (such as steel shots, glass beads, steel grit, quartz sand, copper ore sand, yellow sand, fruit shells, etc.), meeting various process requirements.
8. The indoor air flow in the shot blasting (bead) room circulates from top to bottom, with bright lighting, comfort, and high visibility.
9. Utilizing filter core dust removal technology, the dust emission from the sandblasting (bead) room is significantly lower than the national environmental protection requirements.
10. The sandblasting (ball) room is constructed with foam-insulated color steel panels, offering soundproofing capabilities, and is aesthetically pleasing, sturdy, and airtight.
Dust and Sand Separation System
The material and dust collected from the honeycomb floor must be separated by a sand and dust separator to ensure the sand can be recycled. The efficiency of the separator directly impacts the sandblasting performance of the sandblasting machine and the filtration performance of the dust collector.
The sand separator utilizes a two-stage air separator specifically designed for our shot blasting systems. The first stage is an exclusive cyclonic inertia separator, and the second stage is an air-blowback separator. It effectively sorts the recovered reusable sand, crushed sand, dust, scale, and other impurities. The whole sand is returned to the shot blasting machine for continuous recycling, while the dust and crushed sand are sent to the dust collector, filtered, and stored for scheduled cleaning.
By adjusting the regulating mechanism on the dust separator, the diameter of the separated sand material can be regulated. Special customized dust separators can achieve grading, segmenting (different particle sizes), and round selection of sand materials.
