Shot Blasting Machine for Inner and Outer Walls of Tower

This machine can also be used to clean the interior and exterior walls of wind turbine towers and large pipelines. Shot blasting quickly removes scale, old paint, and other contaminants from the surfaces of pipes and steel tanks. Once a certain surface roughness is achieved, a protective coating can be applied to improve paint film adhesion, fatigue strength, and corrosion resistance, thereby enhancing the workpiece's inherent quality and extending its service life.

Shot blasting technology is used to clean the interior walls of cylindrical objects. It primarily utilizes compressed air as a power source, accelerating the projectiles to generate a certain amount of kinetic energy. This technology then sprays the inner walls of pipe fittings and cylinders. When a pipe fitting is positioned in the spray gun chamber, the spray gun automatically extends into the pipe cavity and moves up and down within the cavity, completing a comprehensive spray cleaning of the pipe's interior. 

The tower exterior wall shot blasting machine is a new type of shot blasting equipment developed by our company, suitable for rust removal on the exterior walls of wind turbine towers. A high-efficiency motor-connected shot blasting machine uses a rotating shaft to compensate for the swing angle, ensuring good contact between the shot blasting machine and the tower. This closed-type shot blasting machine uses the tower's self-rotation and the shot blasting machine's movement along the tower's axis to clean and remove rust. This allows for quick and clean blasting of the outer wall of the wind turbine tower (steel pipe).

The inner wall shot blasting trolley travels on the beam while blasting the shot blasting trolley. This travel is frequency-controlled, resulting in a silver-white, spiral-shaped stripe of a certain width on the surface of the tower. By matching the trolley's travel speed with the tower's rotational speed so that adjacent silver-white stripes overlap, the tower surface is completely free of rust. The steel pipe sandblasting method can be modified as follows: during the sandblasting process, the sandblasting trolley does not move simultaneously. After completing one lap, it moves to another working position and then blasts another lap. This continues until the inner wall of the steel pipe is completely sandblasted.

▶ Product Structure

Frame: As the equipment's supporting structure, the frame ensures the stable operation of all components. Tower cleaning machines typically require a larger frame to accommodate the cleaning of large towers.
Shot blaster: The shot blaster is the core component of a tower cleaning machine and is typically a centrifugal type. Steel shot is propelled at high speeds onto the interior and exterior surfaces of the tower, completing the cleaning process. The arrangement of the shot blasters can be adjusted to meet cleaning requirements, ensuring uniform cleaning of every surface area.
Conveyor system: During the cleaning process, the tower rotates or rolls through a specialized conveyor system to ensure uniform cleaning. The conveyor system typically features a conveyor system suitable for large towers, such as a hanging, roller, or track system.
Dust removal system: To control dust generated during the cleaning process, the cleaning machine is equipped with efficient dust removal equipment to prevent dust contamination and improve cleaning efficiency. Common dust removal methods include bag filters and cyclones.

Control system: Modern tower inner and outer wall shot blasting machines are equipped with advanced automatic control systems that can monitor and adjust various parameters of the cleaning process in real time, such as shot blasting speed, cleaning time and steel shot projection amount, to ensure the stability of the cleaning effect.

▶ Advantages

Efficient Cleaning: Shot blasting technology quickly removes rust, scale, oil, and other impurities from tower surfaces, offering high cleaning efficiency and suitability for large-scale production. Shot blasting is particularly effective for surface treatment of large towers.
Ultimate Cleaning: The shot blaster design and the tower's rotating transmission system ensure uniform cleaning of both the inner and outer tower surfaces, eliminating the incomplete cleaning that can occur with traditional manual cleaning or sandblasting.
Enhanced Adhesion: The higher surface roughness of the shot blasted tower promotes better adhesion of coatings, plating, or anti-corrosion layers, enhancing the tower's corrosion resistance and durability.
Energy-Saving: The shot blasting machine is equipped with an efficient dust removal system that effectively controls dust and exhaust gas generated during the cleaning process, meeting modern environmental standards. Furthermore, its low energy consumption helps reduce production costs.
High Automation: Modern tower inner and outer wall shot blasting machines are equipped with automated control systems, reducing manual intervention and improving production efficiency. Simple operation and adjustable parameters ensure more stable and precise cleaning results.

Strong adaptability: The equipment is suitable for cleaning towers of different types and specifications. It can adjust the projection amount, projection angle and cleaning time of the shot blasting machine as needed to meet different production needs.

▶ FAQ

What is the main function of a tower internal and external wall shot blasting machine?
The main function of a tower internal and external wall shot blasting machine is to remove rust, scale, oil, and other impurities from the tower surface, improve the tower's surface roughness, enhance the adhesion of the coating or anti-corrosion layer, and ensure the tower's corrosion resistance and service life.

 
How is uniform cleaning performance ensured?
The precise design of the tower's rotating transmission system and shot blasting wheels allows the shot blasters to evenly distribute steel shot across the tower's internal and external surfaces, ensuring that every surface is thoroughly cleaned. Furthermore, the machine's automatic control system adjusts the shot blaster's projection angle and speed to optimize cleaning performance.

 
How frequently does a tower internal and external wall shot blasting machine require maintenance?
A tower internal and external wall shot blasting machine requires regular maintenance to ensure stable operation. Key maintenance tasks include inspecting the shot blasting wheels for wear, cleaning the dust removal system, replacing the steel shot, and checking the electrical control system. Regular inspection and maintenance can effectively extend the equipment's service life and maintain excellent cleaning results.
