Introduction to Principle:
The internal chamber of the sandblasting room forms an air flow layer from top to bottom under the influence of wind, and the abrasive is jetted onto the workpiece surface under the action of compressed air to cut off chips. Some abrasive chips break into dust, which is then carried by the downward airflow to mix with more abrasive and rust particles, and returns to the sorting system through 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 re-released into the atmosphere or recycled for use in the sandblasting room. The entire process is sealed, with no dust leakage, ensuring safety and environmental protection.
Mechanical recirculating sandblasting room complete set mainly consists of the sandblasting room body, lighting system, air-powered 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 no pollution; sandblasting is conducted in a sealed environment, and the 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 dust collector, with the emission concentration of the filtered gas exceeding national standards.
★Automatic Recirculation: The system utilizes an air-powered material recovery floor for automatic sand recycling.
★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 pneumatic principles to effectively segregate sand materials, impurities, and dust. Recyclable sand materials return to the storage bin, while non-recyclable dust and impurities are transported to the dust collector for refined filtration.
★ Filter Core Dust Removal: The system employs filter core dust removal method
★ Imported Filter Media: Made from imported long fiber materials, the filter cores offer a large filtering area, with each core having twice the filtering 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 utilizes PLC + touch screen display, enabling automatic operation mode and manual control mode.
★Efficient Cleaning: Utilizes a high-pressure double-cylinder continuous sandblasting machine, with a single nozzle cleaning area 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, no need for traditional conveying equipment such as conveyors, belt machines, and bucket elevators, which avoids sand and dust wear, clogging, and other issues during sand material transportation and lifting. This results in a low failure rate and minimal maintenance work.
3. Equipped with abrasive separation and sorting devices, the abrasive is automatically recycled, enhancing utilization rate and sandblasting cleaning efficiency.
4. The abrasive recycling separator and dust removal share a single fan, achieving multiple uses with one fan, 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, resulting in high sandblasting efficiency and the working pressure can be infinitely adjusted.
6. Utilizes tungsten carbide durable sandblasting nozzles with an average lifespan of 800-1000 hours.
7. The sandblasting room can use different materials and grain sizes of abrasive media (such as steel shot, glass beads, steel grit, quartz sand, copper ore sand, yellow sand, fruit shells, etc.), meeting various process requirements.
8. The sandblasting (bead) room features an indoor air circulation pattern that moves from top to bottom, ensuring bright, comfortable lighting with high visibility.
9. Utilizing filter core dust removal technology, the dust emissions from the sandblasting room are significantly lower than the national environmental protection requirements.
10. The sandblasting (bead) room is constructed with polyfoam sandwich colored panels, offering sound absorption properties, aesthetics, strength, and airtightness.
Dust Separation System
The material and dust recovered from honeycomb flooring must be sorted by a sand-dust separator before the sand can be recycled. The efficiency of the sand-dust 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, followed by an air-blowing separator. It effectively sorts the reclaimed 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 periodic cleaning.
By adjusting the regulating mechanism on the dust separator, the size of the separated sand material diameter can be regulated. Customized dust separators can achieve grading, segmenting (different particle sizes), and round selection of sand material.
