The machine's structure consists of a feeding mechanism, infeed roller conveyor, shot blasting machine, discharge roller conveyor, unloading mechanism, pneumatic control system, electrical control system, and dust removal system. The shot blasting machine comprises a shot blasting chamber, shot blaster assembly, shot chute and grid, shot separator, elevator, platform ladder and railings, and shot supply system. This machine utilizes PLC electrical control, pneumatic valve and cylinder control for the loading and unloading system, a controllable shot gate, and shot conveying fault detection to achieve full machine automation. Therefore, it features high productivity, high reliability, and an advanced degree of automation.
1. Workpiece Cleaning Sequence:
Feeding support → Feeding mechanism → Enters shot blasting chamber → Shot blasting (workpiece rotates while moving forward) → Exits shot blasting chamber → Unloading mechanism → Unloading support
2. Shot Circulation Sequence:
Shot storage → Flow control → Shot blasted workpiece → Bucket elevator vertical lifting → Shot and slag separation → (Recirculation)
Shot Blasting Unit: The shot blasting unit selected for this equipment is a single-disc curved blade unit. It is precision-machined and installed using DISA technology. It mainly consists of an impeller, main shaft and main bearing housing, cover, directional sleeve, shot distribution wheel, blades, guard plate, transmission device, motor, and bearings. This shot blasting unit has a single-disc structure, resulting in good shot inflow performance and a large shot volume per unit power. The impeller body is close to the main shaft end, with a reasonable and compact structure and convenient maintenance.
Dust Removal: Pulse, vibration, or reverse airflow cleaning can easily regenerate the filter cartridge, resulting in good dust removal effect. Cartridge filter dust removal technology is a replacement product for bag filter dust removal and is a filtration technology of the 21st century.
