Design background and motion system of environmental protection and energy saving sandblasting machine

useEnvironmental protection and energy saving sandblasting machineSandblasting to remove rust is the main method of surface pretreatment for pipeline coating. The patch area of ​​the submarine pipeline is the bottleneck of the entire pipeline for anticorrosion, and the quality of its surface derusting treatment directly affects the frequency of submarine pipeline failure accidents. At present, the use of sandblasting and rust removal technology is gradually restricted due to its serious environmental pollution and endangering human health. Although wet sandblasting and ultra-high pressure water rust removal technology avoid environmental pollution, it is easy to produce floating rust after wet sandblasting. However, the ultra-high pressure water rust removal technology is expensive and cannot be widely adopted. The development of environmental protection and energy saving sandblasting machine provides an effective way to solve the above problems.

The environmental protection and energy-saving sandblasting machine is an automatic rust removal device for pipe joints, which can reduce pollution to the surrounding environment on a larger scale, improve the working environment of workers, increase their work efficiency, and ensure the quality of pipe joints. Since environmental protection and energy-saving sandblasting machines are usually used in environments with very harsh working conditions, this places higher requirements on their control systems. The advantages and disadvantages of the environmental protection and energy-saving sandblasting machine control systems determine the overall performance of the equipment and affect The effect of sandblasting and rust removal.

The motion system of the environmentally friendly and energy-saving sandblasting machine can be simplified into a type of tandem mechanism. The structure of the motion system is shown in Figure 1. In the figure, A is the motion system body, B is the moving guide rail of the motion system, C is the pipeline, and D is the sandblasting area. It can be seen from Figure 1 that the feed mode of the motion system includes rotary feed along the orbital direction and axial feed along the pipe axis. When the movement system of the environmental protection and energy-saving sandblasting machine moves in a circular motion along the guide rail, its rotary feed motion can be transformed into a rotary motion around the axis of the pipe, and the radius of rotation is r+r.
