Principle Overview:
The internal chamber of the sandblasting room forms an air flow layer from top to bottom 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 abrasive particles break into dust, which is then carried down by the flowing air. The air, mixed with the abrasive material and rust particles, returns to the selection system through a honeycomb back-sanding floor. After selection, reusable sand is returned to the storage box and automatically added to the sandblasting system for recycling in accordance with the sandblasting requirements. 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 re-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 circulating sandblasting room complete set mainly consists of the sandblasting room body, lighting system, air dynamic recovery floor, separator, sandblasting system, dust collector, fan, control system, workpiece conveying system, and operator protection system.
Features of Mechanical Recirculating Sand Blasting Booth:
★Environmental Protection: The fan is powered by electricity, ensuring cleanliness and no pollution; sandblasting is performed in a sealed environment, with sand material being recovered in enclosed pipes, thus preventing any leakage of sand or dust that could cause pollution; dust is filtered through a filter core dust collector, with the emission concentration of the filtered gas exceeding national emission standards.
★Automatic Recirculation: The system employs an air-powered recycling floor to achieve automatic reuse of sand material.
★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, 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 a filter core dust removal method, ensuring filtration efficiency.
★ Imported Filter Media: Made from imported long fiber materials, the filter cores have a large filtration area, with each core having twice the filtration area of a standard 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, allowing for 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:
No deep excavation required (or no pit required at all), low infrastructure costs, and 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 the conveying equipment, bearings, and motors during transportation and lifting processes. It boasts 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 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 independently, offering 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 grain sizes of abrasive materials (such as steel shots, glass beads, steel grit, quartz sand, copper ore sand, yellow sand, fruit shells, etc.), meeting different process requirements.
8. The sandblasting (bead) room features an indoor air circulation that 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 (ball) room is constructed with foam plastic sandwich color steel panels, featuring soundproofing capabilities, aesthetics, strength, and airtightness.
Dust and Sand Separation System
The sand and dust recovered from the honeycomb flooring must be separated using a sand-dust separator before the sand can be recycled. The efficiency of the sand-dust separator directly impacts the sandblasting performance of the sandblaster 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, followed by an air-blowing separator. It effectively sorts recycled reusable sand, crushed sand, dust, oxide scale, and other impurities. The whole sand is returned to the shot blasting machine for continuous recycling, while the dust and fine 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, segmenting (different particle sizes), and round selection of sand material.
