Principle Overview:
The internal chamber of the sandblasting room forms an air flow layer from top to bottom due to the wind force. Abrasive material is ejected onto the workpiece surface after being jetted with compressed air, cutting away chips. Some of the abrasive chips break into dust, which is then carried by the downward airflow, re-mixed with the abrasive material and rust particles, and returned to the selection system via the honeycomb back-sanding floor. After sorting, reusable sand is returned to the storage bin and automatically added to the sandblasting system for recycling according to demand. 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 recycled for use in the sandblasting room. The entire process is enclosed, with no dust leakage, ensuring safety and environmental protection.
Mechanical circulating sandblasting rooms are complete sets of equipment consisting of the sandblasting room body, lighting system, air-powered recovery floor, separator, sandblasting system, dust collector, fans, control system, workpiece conveying system, and operator protection system.
Mechanical recirculating sandblasting booth features:
★Eco-Friendly: The fan is electrically driven, clean and pollution-free; sandblasting operates in a sealed environment, and the sand is recovered in enclosed pipelines, ensuring no leakage of sand or dust particles that could cause pollution around the area; dust is filtered through a core dust collector, with the exhaust gas concentration post-filter exceeding national emission standards.
★Automatic Recirculation: The system employs an aerodynamic material recovery floor for the automatic recirculation of sand material.
★Dual-purpose: The wind generated by the fan not only meets the conveying of sand materials but also serves for system dust removal.
★Automatic Sorting: The separator utilizes aerodynamic principles to effectively sort sand, impurities, and dust, allowing recyclable sand to return 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, ensuring high filtration efficiency.
★ Imported Filter Media: Made from imported long fibers, the filter cores offer a large filtration area, with each core having twice the filtration 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, 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 (or can skip excavation), 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. It boasts a low failure rate and requires minimal maintenance work.
3. Equipped with abrasive separation and sorting devices, the abrasive is automatically recycled, enhancing utilization rates and sandblasting cleaning efficiency.
4. The abrasive recycling separation, sorting, 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 multiple high-speed nozzles to operate with a single sand pot, each nozzle can be controlled individually, offering high sandblasting efficiency, and the working pressure can be infinitely adjusted.
6. Utilizes carbide-tough abrasive nozzles with an average lifespan of 800-1000 hours.
7. The sandblasting room can utilize different materials and particle sizes of abrasive materials (such as steel shots, glass beads, steel sand, quartz sand, copper ore sand, yellow sand, fruit shells, etc.), catering to various process requirements.
8. The shot blasting (bead) room features an indoor air flow that circulates from top to bottom, with bright and comfortable lighting, and high visibility.
9. Utilizing filter core dust removal technology, the dust emissions from the sandblasting (bead) room are significantly lower than the national environmental protection standards.
10. The sandblasting (bead) room is constructed with foam sandwich color steel panels, featuring sound absorption capabilities, aesthetics, durability, and airtightness.
Dust and Sand Separation System
The materials and dust recovered from honeycomb flooring must be separated by a sand-dust separator to ensure the sand is 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 a unique cyclonic inertial separator, and the second stage is 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 recycling, while the dust and crushed sand are sent to the dust collector, filtered, and stored for regular 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 material.
