Principle Overview:
The interior of the shot blasting room forms an air flow layer from top to bottom of the room due to the wind force. Abrasive material, after being acted upon by compressed air, becomes a solid-gas mixture and is jetted onto the workpiece surface for cutting. Some abrasive particles break into dust and are carried downward by the air flow, re-mixing with the abrasive and rust removal impurities and returning to the separator system via the honeycomb back sand floor. After separation, recyclable sand material returns to the storage bin and automatically adds sand to the shot blasting system for cyclic use. Dust and impurities that cannot be reused are transported to a 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 shot blasting room. The entire process is sealed, with no dust leakage, ensuring safety and environmental protection.
The complete mechanical cyclone sandblasting room equipment 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.
Mechanical circulating sandblasting room features:
★Environmental Protection: The fan uses electric drive, clean and pollution-free; sandblasting operates in a closed environment, and the sand is recycled through enclosed pipes, 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 material recovery floor for automatic sand 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 utilizes the principles of aerodynamics to effectively sort sand, impurities, and dust. The recyclable sand returns to the storage bin, while the 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 fiber material, offering a larger filtering area; each filter element has twice the filtering area of a standard filter element.
★Automatic Control: Automation is achievable for sand recycling, sorting, nozzle control, dust removal, and sandblasting pot operations. The system features automatic fault alarms and prompts.
High Integration: The control system uses PLC+touch screen display, allowing for automatic operation mode and manual control mode.
★High-Efficiency Cleaning: Equipped with a high-pressure dual-cylinder continuous sandblasting machine, each nozzle can clean an area of 10 ~ 30 m²/h.
Compared to traditional shot blasting rooms, it boasts the following distinctive features:
No deep excavation required (excavation can also be omitted), low infrastructure costs, and a short construction period.
2. Equipped with sand-suction flooring, it eliminates the need for traditional conveying equipment such as augers, belt conveyors, and bucket elevators. This reduces wear, clogging, and other issues caused by sand and dust on conveying equipment, bearings, and motors during sand material transport and lifting. It boasts a low failure rate and requires minimal maintenance work.
3. Equipped with abrasive separation and sorting devices, the abrasive is automatically recycled, improving utilization rates and sandblasting cleaning efficiency.
4. The abrasive recycling separator and dust removal systems share a single fan, achieving multiple uses with one wind source, saving 30% of energy compared to traditional sandblasting rooms.
5. The sandblasting system allows one sand pot to power multiple high-speed喷枪 simultaneously, each gun can be controlled individually, resulting in high sandblasting efficiency and pressure that 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 various materials and different grain sizes of abrasive media (such as steel shots, glass beads, steel grit, quartz sand, copper ore sand, yellow sand, fruit shells, etc.), catering to diverse process requirements.
8. The indoor air circulation in the shot blasting (bead) room moves from top to bottom, with bright lighting, comfort, and high visibility.
9. Utilizing filter core dust removal technology, the dust emission from the sandblasting (pellet) room is significantly lower than the national environmental protection requirements.
10. The sandblasting (bead) room is constructed with foam-insulated color steel panels, featuring noise reduction capabilities, aesthetic appeal, durability, and airtightness.
Dust Separation System
Material and dust are recovered from the honeycomb floor. They must be separated by a sand and dust separator before the sand can be recycled. The efficiency of the separator directly affects 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 sandblasting systems. The first stage is a unique cyclonic inertial separator, and the second stage is an air-blowing separator. It effectively sorts returned reusable sand, crushed sand, dust, oxide scale, and other impurities. The whole sand is returned to the sandblasting machine for continuous reuse, while the dust and fine sand are sent to the dust collector, filtered, and stored for periodic cleaning.
By adjusting the regulating mechanism on the dust separator, the diameter of the separated sand material can be regulated. Special-order dust separators can achieve grading, segmenting (different particle sizes), and round selection of sand materials.
