Principle Overview:
The interior of the sandblasting room forms an air flow layer from the top to the bottom of the room under the influence of wind. The abrasive material is jetted onto the workpiece surface, cut away by compressed air, and some of the abrasive chips are broken down into dust, which is then carried down by the airflow and re-mixed with the abrasive material and rust particles, before returning to the separator system through the honeycomb back-sand floor. After sorting, reusable sand is returned to the storage box and automatically added to the sandblasting system for recycling according to the sandblasting needs; dust and impurities that cannot be reused are transported to the dust collector for fine filtration. The dust settles in the waste bin and is recycled, while the filtered gas is either released into the atmosphere or reused in the sandblasting room. The entire process is sealed, with no dust leakage, ensuring safety and environmental protection.
Mechanical cyclic sandblasting room complete set mainly 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.
Features of mechanical circulating sandblasting room:
★ Eco-Friendly: Fans are powered electrically for clean, pollution-free operation; sandblasting is performed in a sealed environment, and sand is recovered through enclosed pipelines, thus preventing any sand or dust leakage that could cause surrounding pollution; dust is filtered through a core filter, with the emission concentration of the filtered gas exceeding national emission standards.
★Automatic Recirculation: The system uses an air-powered recovery floor for sand material to achieve automatic recycling.
★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 separator uses the principle of air dynamics to effectively sort sand materials, impurities, and dust. The recyclable sand materials return to the storage bin, while the non-recyclable dust and impurities are transported to the dust collector for refined filtration.
★ Filter Core Dust Removal: The system employs filter core dust removal method, ensuring filtration efficiency.
★ Imported Filter Media: Made from imported long fiber materials, offering a large filtration area, with each filter core having twice the filtration area of a standard filter core.
★Automatic Control: Automation of sand recycling, sorting, nozzle control, dust removal, and sandblasting pot operations. The system features automatic fault alarm and prompt.
High Integration: The control system utilizes PLC + touch screen display, enabling both automatic operation mode and manual control mode.
★Efficient Cleaning: Utilizes a high-pressure dual-cylinder continuous sandblasting machine, with a single nozzle capable of cleaning up to 10~30 m2/h.
Compared to traditional shot blasting rooms, it boasts the following distinct features:
No need for deep excavation (or no excavation required), low infrastructure costs, and a short construction period.
2. Equipped with sand-suction flooring, eliminating the need for traditional conveying equipment such as augers, belt conveyors, and bucket elevators. This design prevents wear, clogging, and other issues caused by sand and dust during transportation and lifting processes, resulting in a low failure rate and minimal 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 multiple uses with one wind source, saving 30% of energy compared to traditional shot blasting rooms.
5. The sandblasting system allows one sand pot to power multiple high-speed spray guns, each of which can be controlled individually. 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 sandblasting (bead) room features an indoor air circulation movement from top to bottom, with bright lighting, comfort, and high visibility.
9. Utilizing filter core dust removal technology, the dust emission from the shot blasting room is significantly lower than the national environmental protection requirements.
10. The sandblasting (bead) room is constructed with foam-insulated color steel panels, featuring sound-dampening capabilities, and is aesthetically pleasing, sturdy, and airtight.
Dust Separation System
The material and dust recovered from the honeycomb flooring must be sorted through a sand-dust separator to separate the sand from the dust, allowing the sand to continue in the recycling process. The efficiency of the sand-dust separator directly impacts the sandblasting performance of the sandblasting machine and the filtration performance of the dust collector.
The sand separator employs a two-stage air separator, specifically designed for our shot blasting systems. The first stage is a unique cyclone inertial separator, while the second stage is an airflow backblowing separator. It efficiently sorts reusable sand, crushed sand, dust, scale, and other impurities. The complete sand is returned to the shot blasting machine for continuous recycling. Dust and broken sand are then sent to the dust collector, filtered, and stored for periodic cleaning.
Adjusting the regulating mechanism on the dust separator allows for the regulation of the diameter of the separated sand material. Customized dust separators can achieve grading, segmentation (different particle sizes), and round selection of sand material.
