Brief introduction of construction technology of steel pipe derusting shot blasting machine
1. Definition
    Steel pipe derusting shot blasting machine is a cleaning machine for cleaning the outer wall of the steel pipe. The centrifugal force generated by the blade of the shot blasting machine at high speed is used to shoot the abrasive (steel shot, steel wire section, diamond steel sand, etc.) at a high linear velocity To the surface of the outer wall of the pipe to be treated, it has a knocking and grinding effect to remove the oxide layer and rust on the surface, let the surface leak out the true color of the metal, and provide the roughness with anchoring ability to the coating. It is a more advanced mechanical treatment method for derusting steel pipes. It not only has high production efficiency, but also has low cost and high degree of automation. It can realize assembly line operation and less environmental pollution.
Second, the principle
    When the steel pipe placed on the cone roller is automatically input into the blasting area of the blasting machine room, the circumferential surface of the steel pipe rotating while advancing continuously receives the high-speed pill flow thrown by the high-efficiency powerful blasting machine to throw the rotating steel pipe located in the chamber On the surface, remove the sticky sand, rust layer, welding slag, oxide scale and debris on the surface, so as to obtain a fine and smooth surface, improve the adhesion between the paint film and the steel surface, and improve the fatigue resistance and corrosion resistance of the steel , To improve the inherent quality of steel and prolong its service life. In the process of shot blasting by the shot blasting machine, the scattered dust mixture passes through the chamber funnel and is conveyed horizontally and vertically in the lower part of the elevator, and then lifted into the separator at the upper part of the shot blasting machine. The hopper is used for the circulation of the shot blaster; the dust generated in the shot blasting cleaning is sent to the dust removal system by the exhaust pipe, and the purified gas is discharged into the atmosphere. purpose.
3. Production process
1. Steel pipe shot blasting sequence
   Steel pipe feeding bracket → loading mechanism feeding → entry shot blasting chamber → shot blasting (steel pipe rotating while advancing) → steel pipe feeding out shot blasting chamber → unloading mechanism unloading → steel pipe unloading bracket.
2. Projectile cycle sequence
    Projectile storage → flow control → shot blasting processing workpiece → bucket elevator vertical lifting → shot slag separation → (recycling).
