Principle Overview:
The internal chamber of the shot blasting room forms an air flow layer from top to bottom under the influence of wind, while the abrasive material is jetted onto the workpiece surface by compressed air, cutting away chips. Some of the abrasive chips break 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-to-sand floor. After sorting, reusable sand is returned to the storage bin and automatically added to the shot blasting system for recycling in accordance with the blasting requirements; 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 reused in the shot blasting room. The entire process is sealed, with no dust leakage, ensuring safety and environmental protection.
The complete set of mechanical recirculating shot blasting room equipment consists of the blasting room body, lighting system, air dynamic recovery floor, separator, blasting system, dust collector, fan, control system, workpiece conveying system, and operator protection system.
Mechanical circulating 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 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 utilizes an airdynamic floor to recycle sand material, ensuring automatic reuse.
★Dual-purpose: The wind generated by the fan not only meets the requirements for conveying sand material but also serves for dust removal in the system.
★Automatic Sorting: The separator utilizes pneumatic 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 refined 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, offering a larger filtration area, with each filter core having twice the filtration area of a standard filter core.
★Automatic Control: Automation is achievable for sand recycling, sorting, nozzle control, dust removal, sandblasting pot operation, with the system automatically alerting for faults.
High Integration: The control system utilizes PLC and a 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 (pellet) rooms, it boasts the following distinctive features:
No deep excavation required (or can be omitted), low infrastructure costs, and a short construction period.
2. Equipped with sand-suction floor, no need for traditional transport equipment such as conveyors, belt machines, bucket elevators, etc. This avoids the wear, clogging, and other issues caused by sand and dust during transportation and lifting processes, resulting in low failure rates and minimal maintenance work.
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 and dedusting share a single fan, utilizing the wind for multiple purposes, saving 30% of energy compared to traditional sandblasting rooms.
5. The sandblasting system allows one sand pot to power multiple high-speed nozzles, each of which can be controlled individually. The sandblasting cleaning efficiency is high, and the working pressure can be infinitely adjusted.
6. Utilizes carbide-toughened sandblasting nozzles with an average lifespan of 800-1000 hours.
7. The sandblasting room can utilize various materials and different grain sizes of abrasive media (such as steel shot, glass bead, steel grit, quartz sand, copper ore sand, yellow sand, fruit shells, etc.), meeting various process 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 emissions from the sandblasting room are 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
The materials and dust recovered from honeycomb flooring must be separated using a sand-dust separator to ensure 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 dust separator utilizes a two-stage air separator specifically designed for our sandblasting systems. The first stage is a unique cyclone inertial separator, followed by an airflow backblowing separator. It effectively sorts the recycled reusable sand, crushed sand, dust, oxide scale, and other contaminants. The whole sand is returned to the sandblasting machine for continuous recycling, while the dust and fine sand are sent to a dust collector, filtered, and stored for regular cleaning.
Adjusting the regulating mechanism on the dust separator can alter the diameter of the separated sand material. Custom-made dust separators can achieve grading, segmenting (various particle sizes), and round selection of sand material.
