Principle Overview:
The internal chamber of the sandblasting room forms an air flow layer from top to bottom under the action of wind, and the abrasive is ejected onto the workpiece surface, cutting away chips, with some chips breaking into dust. The downward airflow carries the dust, mixing it with more abrasive and rust particles, and returns them to the selection system via the honeycomb back-sanding floor. After sorting, reusable sand is returned to the storage bin and automatically recycled to the sandblasting system as needed. 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 recycling sandblasting booth complete set mainly consists of the sandblasting booth 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 room features:
★Environmental Protection: The fan is powered electrically, ensuring cleanliness and zero pollution; sandblasting is performed in a sealed environment, and sand material is recycled in enclosed pipes, preventing any leakage of sand or dust that could cause surrounding pollution; dust is filtered by a core filter dust collector, with the排放 concentration of the gas after filtration exceeding national emission standards.
★Automatic Recycling: The system features an aerodynamic floor for sand material automatic 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 the principles of pneumatics 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 fine filtration.
★ Filter Core Dust Removal: The system employs a filter core dust removal method, ensuring filtration efficiency.
★ Imported Filter Media: Made from imported long fiber material, the filter cores have 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 alarm and prompt.
High Integration: The control system uses 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 an area of up to 10 ~ 30 m²/h.
Compared to traditional shot blasting rooms, it boasts the following distinct features:
1. No need for deep excavation (excavation can be omitted), low infrastructure costs, and a short construction period.
2. Equipped with sand-suction floor, it eliminates the need for traditional conveyors, belt conveyors, bucket elevators, etc., thereby avoiding wear, clogging, and other issues caused by sand and dust on the conveying equipment, bearings, and motors during sand material transportation and lifting. This results in a low failure rate 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, sorting, and dust removal systems share a single fan, achieving multiple uses with one fan, saving 30% of energy compared to traditional shot blasting rooms.
5. The sandblasting system allows multiple high-speed nozzles 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 shot blasting (bead blasting) room features an indoor air flow that circulates from top to bottom, with bright lighting, comfort, and high visibility.
9. Utilizing filter core dust removal technology, the dust emission from our shot blasting room is significantly lower than the national environmental protection standards.
10. The shot blasting (bead) room is constructed with foam plastic insulated color steel panels, featuring soundproofing capabilities, aesthetic appeal, durability, and airtightness.
Dust and Sand Separation System
The sand 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 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 sandblasting system. The first stage is a unique cyclonic inertial separator, and the second stage is an airflow backblowing separator. It effectively sorts recycled reusable sand, crushed sand, dust, scale, and other impurities. The whole sand after separation returns to the shot blasting machine's main unit for continuous reuse, while the dust and fine sand are sent to a dust collector, filtered, and stored for periodic 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.
