Principle Introduction:

The internal chamber of the sandblasting room forms an air flow layer from top to bottom under the influence of wind. The abrasive material, after being compressed by air, is ejected onto the workpiece surface to cut off chips. Some abrasive chips break down into dust, which is then carried down by the airflow. The dust is mixed with abrasive material and rust particles, and returns to the separator system through the honeycomb back-sand floor for sorting. After sorting, the recyclable sand is returned to the storage bin and automatically added to the sandblasting system for reuse as needed. The dust and impurities that cannot be reused are brought to the dust collector for fine filtration. The dust settles in the waste bin and is recycled, while the filtered gas is released back into the atmosphere or reused in the sandblasting room. The entire process is sealed, with no dust leakage, ensuring safety and environmental protection.

The complete set of mechanical cyclone sandblasting recovery room equipment 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.

Mechanical recirculating sandblasting booth features:

★Environmental Protection: The fan is driven by electricity, ensuring cleanliness and pollution-free operation; sandblasting is conducted in a sealed environment, and the sand material is recycled through enclosed pipelines, thus preventing any leakage of sand or dust that could cause pollution; dust is filtered through a core filter dust collector, with the exhaust gas concentration after filtration exceeding national emission standards.

★Automatic Recirculation: The system uses an air-powered recycling floor to achieve automatic reuse of sand materials.

★Dual-purpose: The wind generated by the fan not only meets the conveying of sand materials but also serves as system dust removal.

★Automatic Sorting: The separator uses the principles of aerodynamics to effectively sort sand, impurities, and dust. Recyclable sand is returned 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 method, ensuring high filtration efficiency.

★ Imported Filter Media: Made from imported long fiber materials, the filter cores have a large filtering area, with each filter 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 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 up to 10~30 m²/h.

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

1. No need for deep excavation (or no pit required), 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 design avoids sand and dust wear, clogging, and other issues in the transportation and lifting process, 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 rates and sandblasting cleaning efficiency.

4. The abrasive recycling separator and dust removal systems share a single fan, achieving multiple uses with one wind, saving 30% of energy compared to traditional sandblasting rooms.

5. The sandblasting system allows for multiple high-speed nozzle guns to operate with a single sand pot, each gun being individually controlled for high sandblasting efficiency and infinitely adjustable working pressure.

6. Utilizing carbide-tough shot blasting nozzles with an average lifespan of 800-1000 hours.

7. The sandblasting room can utilize various materials and grain sizes of abrasive media, such as steel shots, glass beads, steel sand, quartz sand, copper ore sand, yellow sand, fruit shells, etc., to meet different process requirements.

8. The sandblasting (pellet) 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 (bead) room is significantly lower than the national environmental protection standards.

10. The sandblasting (bead) room is constructed with foam plastic sandwich colored panels, featuring soundproofing capabilities, aesthetics, strength, and airtightness.

Dust and Sand Separation System

The materials and dust recovered from the honeycomb flooring must be separated by 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 employs a two-stage air separator specifically designed for our sandblasting systems. The first stage is a unique cyclonic inertial separator, followed by a reverse air jet separator. It effectively sorts returned reusable sand, crushed sand, dust, oxide scale, and other contaminants. The whole sand is returned to the main unit of the sandblasting machine for continuous recycling, while the dust and sand particles are sent to a 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. Special-order dust separators can achieve grading, segmenting (different particle sizes), and round selection of sand material.
