Principle Overview:
The interior of the sandblasting room forms an air flow layer from the top to the bottom of the room due to wind force. The abrasive material is jetted onto the workpiece surface, cut by compressed air, and some abrasive particles are broken into dust. The downward airflow carries the dust back to mix with the abrasive and rust particles, which then return to the selection 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 based on the sandblasting requirements. The non-reusable dust and impurities 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 recycled for use in the sandblasting room. The entire process is enclosed, with no dust leakage, ensuring safety and environmental protection.
Mechanical circulation sandblasting recovery booth complete set is mainly composed 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.
Mechanical Recirculating Sandblasting Booth Features:
★Eco-Friendly: The fan is driven electrically, ensuring cleanliness and no pollution; sandblasting is performed 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 around the area; dust is filtered using a core filter dust collector, with the emissions concentration after filtration exceeding national standards.
★Automatic Recirculation: The system employs an aero-dynamic floor for air recycling, enabling the automatic recirculation of sand material.
★Dual-purpose: The wind generated by the fan meets both the requirement for conveying sand materials and the system's dust removal needs.
★Automatic Sorting: The sorting equipment utilizes pneumatic principles to effectively separate sand, impurities, and dust, with recyclable sand returned to the storage bin and non-recyclable dust and impurities 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 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 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 double-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:
1. No need for deep excavation (or no pit required), low infrastructure costs, and a short construction period.
2. Equipped with sand-suction flooring, eliminating the need for traditional conveyors, belt conveyors, bucket elevators, etc. This design avoids sand and dust wear, clogging, and other issues on the transport equipment, bearings, and motors during sand material transportation and lifting, resulting in a low failure rate and minimal maintenance workload.
3. Equipped with abrasive separation and sorting devices, 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 shot blasting rooms.
5. The sandblasting system allows one sand pot to power multiple high-speed guns, each of which can be controlled individually, resulting in high sandblasting efficiency and adjustable working pressure with infinite adjustment.
6. Utilizing carbide durable sandblasting nozzles with an average lifespan of 800-1000 hours.
7. The shot blasting room can utilize different materials and grain sizes of abrasive media (such as steel shots, 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 movement from top to bottom, with bright lighting, comfort, and high visibility.
9. Employing filter core dust removal technology, the sandblasting room's dust emissions are significantly lower than national environmental protection standards.
10. The shot blasting (bead) room is constructed with foam-insulated color steel sandwich panels, featuring noise reduction capabilities, aesthetics, durability, and airtightness.
Dust and Sand Separation System
Material and dust are recovered from the honeycomb flooring, which must be sorted by a sand-dust separator before the sand can be recycled. The efficiency of the sand-dust separator directly affects 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 shot blasting systems. The first stage is a unique cyclonic inertial separator, followed by an air blast separator. It efficiently separates 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 crushed sand are sent to a 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. Customized dust separators can achieve grading, segmentation (different particle sizes), and round selection of sand materials.
