When the steel pipe outer wall shot blasting machine is working, after the preparation work (dust removal system, separator, elevator, horizontal screw conveyor, vertical screw conveyor, roller conveyor, shot blasting machine, etc.) is completed, the machine starts working normally. Firstly, place the workpiece on the roller conveyor outside the chamber and transport it into the shot blasting cleaning room through the roller conveyor. At this time, open the shot blasting gate to start shot blasting cleaning of the workpiece. After cleaning, close the shot blasting gate and transport the workpiece out of the chamber through the roller conveyor.

Shot blasting treatment is carried out through two fixed shot blasting machines at the top, and the steel pipe is transported in a spiral manner. With the rotation of the steel pipe, the surroundings of the steel pipe are cleaned in all directions, leaving no dead corners. The traveling speed of the steel pipe is adjustable, thus achieving control over the shot blasting effect on the surface of the steel pipe. The steel pipe outer wall shot blasting machine for this shipment is mainly customized according to the customer''s conventional steel pipe size. In order to effectively save equipment costs, the shot blasting machine is fixed to clean single specification steel pipes. Customization can also be made according to customer requirements

The working sequence of this shot blasting cleaning machine is as follows: loading bracket → loading mechanism → entering shot blasting chamber → shot blasting treatment (workpiece rotates while moving forward) → shot storage → flow control → shot blasting treatment workpiece → bucket elevator vertical lifting → shot slag separation → (recirculation) → sending out shot blasting chamber → discharging mechanism → discharging bracket. Due to the use of curved blades in the shot blasting machine, the inflow performance of the shot is improved, the ejection power is increased, and the workpiece is reasonably and compactly ejected without dead corners, making maintenance more convenient.

1. Adopting a centrifugal cantilever type novel and efficient multifunctional shot blasting machine, it has a large shot blasting volume, high efficiency, quick blade replacement, and overall replacement performance, making maintenance convenient.
2. The workpiece continuously passes through the inlet and outlet of the shot blasting machine. To clean steel pipes with significantly different diameters and prevent the projectile from flying out, this machine uses multi-layer replaceable sealing brushes to achieve thorough sealing of the projectile.
3. The use of a full curtain BE type slag separator greatly improves the separation capacity, separation efficiency, and shot blasting quality, reducing the wear and tear on the shot blasting equipment.

The steel pipe outer wall shot blasting cleaning machine uses a roller mechanism. When the steel pipe enters the main shot blasting chamber, the shot blasting machine starts working in sequence. After shot blasting treatment, most of the oxide scale, dirt, and other attachments on the surface of the steel pipe are cleaned up, and the surface of the workpiece can reach Sa2-2.5 level. The working mode of the assembly line is continuous circulation. The shot blasting pellets of the shot blasting system are collected and processed by the circulation processing system, and continue to be used by the shot blasting machine and shot blasting system. The working mode of the circulation system is as follows: scattered pellets are transported to the bucket elevator through the lower longitudinal screw conveyor, lower belt conveyor mechanism, and transverse screw conveyor. The bucket elevator lifts the pellets and debris to the upper part of the cleaning room
