Principle Overview:
The internal compartment of the sandblasting room forms an air flow layer from the top down due to wind force. The abrasive material, under the action of compressed air, becomes a solid-gas mixture and is jetted onto the workpiece surface for cutting. Some of the abrasive fragments break into dust, which is then carried down by the air flow. The downward airflow mixes the dust with abrasive and rust particles, and they return to the separator system via the honeycomb back-sand floor. After sorting, the reusable sand is returned to the storage box and automatically added to the sandblasting system according to demand for recirculation use. The non-reusable dust and impurities are carried to the dust collector for fine filtration, and the dust settles in the waste bin for recycling. The filtered gas is then released into the atmosphere or recirculated for use in the sandblasting room. The entire process is sealed, with no dust leakage, ensuring safety and environmental protection.
Mechanical circulation sandblasting recovery booths are complete sets of equipment consisting of the sandblasting booth body, lighting system, air-powered recovery floor, separator, sandblasting system, dust collector, fan, control system, workpiece conveying system, and operator protection system.
Mechanical circulation sandblasting room features:
★ Eco-Friendly: Fans are electrically driven, clean and pollution-free; sandblasting is conducted in a sealed environment, and the sand is recycled through enclosed pipes, ensuring no leakage of sand or dust that could cause pollution; dust is filtered using a core filter, with the emitted gas concentration exceeding national emission standards.
★Automatic Recirculation: The system utilizes an air-powered recovery floor for the automatic recirculation of sand materials.
★ Dual-purpose: The wind generated by the fan not only meets the requirement for conveying sand material but also serves the system's dust removal.
★Automatic Sorting: The separator uses the principle of air dynamics to effectively sort sand, impurities, and dust, allowing reusable sand to return to the storage bin, while non-reusable dust and impurities are transported to the dust collector for fine filtration.
★ Filter Core Dust Removal: The system employs filter core dust removal method.
★ 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: 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 employs PLC+touch screen display, enabling automatic operation mode and manual control mode.
★High-Efficiency Cleaning: Equipped with a high-pressure dual-cylinder continuous sandblasting machine, each nozzle can clean up to 10 ~ 30 m2/h.
Compared to traditional shot blasting (pellet) rooms, it boasts the following distinct features:
No deep excavation required (excavation can be omitted), low infrastructure costs, and short construction period.
2. Equipped with sand-suction floor, eliminating the need for traditional conveying equipment such as augers, belt conveyors, and bucket elevators. This avoids wear, clogging, and other issues caused by sand and dust on conveying equipment, bearings, and motors during sand material transportation and lifting, resulting in a low failure rate and minimal maintenance workload.
3. Equipped with abrasive separation and sorting equipment, the abrasive is automatically recycled, enhancing utilization rate and sandblasting cleaning efficiency.
4. The abrasive recycling separation, sorting, and dust removal 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 multiple high-speed nozzles to operate with one sand pot, each nozzle can be controlled individually, providing high sandblasting efficiency, and the working pressure can be infinitely adjusted.
6. Utilizes carbide-toughed sandblasting nozzles with an average lifespan of 800-1000 hours.
7. The shot blasting room can utilize various materials and particle sizes of abrasive media (such as steel shot, glass bead, steel grit, quartz sand, copper ore sand, yellow sand, fruit shells, etc.), meeting different process requirements.
8. The shot blasting (bead) room features an indoor air flow that circulates from top to bottom, with bright lighting and a comfortable atmosphere, offering 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 polyurethane foam sandwich colored steel panels, featuring sound absorption properties, aesthetics, strength, and airtightness.
Dust Separation System
Material and dust collected from honeycomb flooring must be separated using a sand-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 sandblasting systems. The first stage is an exclusive cyclonic inertial separator, followed by an air-blowing separator. It effectively sorts returned reusable sand, crushed sand, dust, scale, and other impurities. The whole sand is returned to the sandblasting machine for continuous reuse, while the dust and fines are sent to a 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. Customized dust separators can achieve grading, segmentation (different particle sizes), and round selection of sand materials.
