Principle Overview:

The internal chamber of the sandblasting room forms an air flow layer from top to bottom under the influence of wind, and the abrasive material is jetted onto the workpiece surface under the action of compressed air to remove chips. Some of the abrasive chips break down into dust, which is then carried by the downward airflow to mix with the abrasive material and rust particles, and returns to the sorting system through the honeycomb back-sanding floor. After sorting, the reusable sand is returned to the storage bin and automatically added to the sandblasting system for recycling according to the sandblasting requirements. The non-reusable dust and impurities are transported to the dust collector for fine filtration, and the dust settles in the waste bin for recycling. The gas filtered through the filter core is then 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 cycle sandblasting recovery booths are complete sets of equipment consisting of the sandblasting booth 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 driven by electricity, ensuring cleanliness and pollution-free operation; sandblasting is conducted in a sealed environment, and sand is recycled through enclosed pipelines, thus preventing any leakage of sand or dust that could cause pollution; dust is filtered through a core filter, with the exhaust gas concentration meeting or exceeding national emission standards.

★Automatic Recirculation: The system utilizes an air-powered recycling floor to achieve automatic reuse 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 principles of aerodynamics to effectively sort sand, impurities, and dust. The reusable sand returns to the storage bin, while the 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, ensuring high filtration efficiency.

★ 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 sand blasting pot operations. The system features automatic fault alarms and prompts.

High Integration: The control system utilizes PLC + touch screen display, enabling both automatic operation mode and manual control mode.

★High-Efficiency Cleaning: Equipped with a high-pressure double-cylinder continuous sandblasting machine, a single nozzle can clean an area of 10 ~ 30 m²/h.

Compared to traditional shot blasting rooms, it boasts the following distinct features:

1. No need for deep excavation (or no excavation required), low infrastructure costs, and a short construction period.

2. Equipped with sand-suction floor, eliminating the need for traditional conveying equipment such as conveyors, belt machines, and bucket elevators. This design prevents wear, clogging, and other issues caused by sand and dust on conveying equipment, bearings, and motors during transportation and lifting processes, resulting in a low failure rate and minimal maintenance workload.

3. Equipped with abrasive separation and sorting devices, the abrasive is automatically recycled, improving 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 fan, saving 30% of energy compared to traditional sandblasting rooms.

5. The sandblasting system allows one sand pot to power multiple high-speed guns, each of which can be controlled independently, ensuring high efficiency in sandblasting cleaning and offering stepless adjustment of working pressure.

6. Utilizes carbide durable sandblasting nozzles with an average lifespan of 800-1000 hours.

7. The sandblasting room can utilize various materials and sizes of abrasive media (such as steel shot, glass bead, steel grit, quartz sand, copper ore sand, yellow sand, fruit shells, etc.), meeting different processing 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 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 soundproofing capabilities, aesthetics, durability, and airtightness.

Dust and Sand Separation System

Material and dust are recovered from the honeycomb floor, which must be sorted 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 recyclable sand, crushed sand, dust, scale, and other impurities. The whole sand is returned to the shot blasting machine for continuous recycling, while the dust and crushed sand are sent to the dust collector, filtered, and stored for scheduled cleaning.

By adjusting the regulating mechanism on the dust separator, the diameter of the separated sand material can be regulated. Special customized dust separators can achieve grading, segmenting (different particle sizes), and round selection of sand materials.
