Principle Overview:
The internal chamber of the sandblasting 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 debris. Some of the abrasive debris breaks down into dust, which is then carried by the downward airflow, mixing with more abrasive material and rust particles, and returning to the sorting system via the honeycomb back-sanding floor. After sorting, reusable sand is returned to the storage bin and automatically added to the sandblasting system for recycling in accordance with the sandblasting 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 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.
Mechanical cycle sandblasting recovery 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 circulation sandblasting room 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 around the area; dust is filtered through a core filter dust collector, with the emissions concentration after filtration exceeding national emission standards.
★Automatic Recirculation: The system employs an air-powered recycling floor to achieve automatic recirculation of sand materials.
★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 separator utilizes the principles of aerodynamics to effectively sort sand, impurities, and dust. The recyclable sand returns to the storage bin, while the 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 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, enabling automatic operation mode and manual control mode.
★High-Efficiency Cleaning: Equipped with a high-pressure double cylinder continuous sandblasting machine, the single nozzle can clean up to 10 ~ 30 m²/h.
Compared to traditional shot blasting (pellet) rooms, it features the following distinct characteristics:
1. No need for deep excavation (or no pit required), low infrastructure costs, and short construction period.
2. Equipped with sand-suction flooring, eliminating the need for traditional conveyors, belt conveyors, bucket elevators, etc., it avoids the wear, clogging, and other issues caused by sand and dust on the transport equipment, bearings, and motors during sand material transportation and lifting. This results 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. Material recycling separation, sorting, and dust removal all share a single fan, utilizing it for multiple purposes, resulting in a 30% energy saving compared to traditional sandblasting rooms.
5. The sandblasting system allows multiple high-speed guns to operate with one sand pot, each gun can be controlled individually, offering high sandblasting efficiency, and the working pressure can be infinitely adjusted.
6. Utilizing carbide-tough shot blasting nozzles with an average lifespan of 800-1000 hours.
7. The shot blasting room can utilize different materials and particle sizes of abrasive materials (such as steel shots, glass beads, steel grit, quartz sand, copper ore sand, yellow sand, fruit shells, etc.), catering to various process requirements.
8. The sandblasting (bead) room features an air circulation pattern from top to bottom, with bright lighting, comfort, and high visibility.
9. Utilizing filter core dust removal technology, the dust emission from the sandblasting (pellet) room is significantly lower than the national environmental protection requirements.
10. The sandblasting (ball) room is constructed with foamed plastic sandwich colored panels, offering noise reduction capabilities, as well as being aesthetically pleasing, sturdy, and airtight.
Dust and Sand Separation System
The material and dust recovered from the honeycomb floor must be separated 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 features a two-stage air separator, exclusively designed for our shot blasting systems. The first stage is an innovative cyclonic inertia separator, followed by an airflow backblowing separator. This unit effectively sorts the reclaimed reusable 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 fine sand are sent to a dust collector, filtered, and stored until scheduled cleaning.
By adjusting the regulating mechanism on the dust separator, the diameter of the separated sand material can be regulated. Custom-designed dust separators can achieve grading, segmentation (different particle sizes), and round selection of sand materials.
