It is a kind of steel pipe outer wall shot blasting cleaning equipment designed and manufactured according to user requirements. It is used for the shot blasting cleaning of the steel pipe outer wall. This equipment is suitable for shot blasting and antirust treatment of the outer wall of large steel pipes with a diameter of 800 or more. The steel pipe can be removed by shot blasting. The rust and oxide scale on the surface are prepared for anti-corrosion.

Advantages of large steel pipe outer wall shot blasting machine:

1. The equipment adopts frequency conversion speed regulation, high-speed feeding and feeding, to ensure that the workpiece is completely shot blasted.

2. The shot blasting device adopts upward shot blasting arrangement. Since the bottom surface of steel pipes with different pipe diameters is approximately at the same height when conveyed on the roller table, the shot blaster is projected from bottom to top, and the distance between the projectile and the surface of the steel pipe is basically the same. The steel pipe has the same cleaning effect on the surface. Provide the same conditions for subsequent spraying.

3. The use of a centrifugal cantilever type novel high-efficiency multi-functional shot blasting device, with large shot blasting volume, high efficiency, rapid blade replacement, overall replacement performance, and convenient maintenance.

4. The workpiece continuously passes through the entrance and exit of the shot blasting machine. Because of cleaning the steel pipes with large diameter differences, in order to prevent the projectile from flying out, the machine adopts a multi-layer replaceable sealing brush to achieve a complete seal of the projectile.

6. Equipped with a pellet collecting hopper and a screw conveyor to collect the projectiles carried out and scattered by the workpiece.

6. Equipped with the function of accumulating shot blasting time to guide the replacement of wear parts such as shot blasting blades.

7. Simulated projectile drawings (including the determination of the model, number and spatial arrangement of the shot blasting machine, etc.) and all drawings of the shot blasting machine are drawn by computer-aided design (CAD). The selection and layout of the shot blasting machine are more reasonable. . The utilization rate of projectiles and labor productivity are improved, the cleaning effect is ensured, and the abrasion of the chamber body guard plate is reduced.

8. ZGMn13 is used for protection in the cleaning room, and the guard plate is fixed by special nuts. It is simple and convenient to replace and has a long service life. It is the best room body guard plate in the current shot blasting equipment.

9. The separator adopts the BE type full curtain separator technology from Pangborn, USA, with good separation effect.

10. The projectile control system adopts the pneumatic control valve independently developed by our company, which is simple and reliable.
