Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline spraying, in particular to a zinc spraying device for the inner pipe of a pipeline, and is particularly applicable to zinc spraying on the inner pipe of a ductile iron pipe. Background Art
[0002] Ductile iron pipes are important pipe materials and are widely used in fields such as water supply and gas transmission pipelines. Before casting, magnesium or rare earth magnesium combined nodulizer is added to the molten iron to spheroidize the graphite, reduce stress concentration, and thus have the advantages of high strength, high elongation, impact resistance, corrosion resistance, and good sealing performance.
[0003] During the production of ductile iron pipes, zinc spraying on the inner pipe is required. The currently used inner pipe zinc spraying machine has a complex structure and high cost. This is because the length and diameter of ductile iron pipes are relatively large. When the inner pipe zinc spraying machine sprays zinc on the inner pipe of a ductile iron pipe, it generally needs to rotate and feed simultaneously until the entire inner pipe of the ductile iron pipe is evenly coated with a zinc coating. Making the spray pipe rotate not only requires designing dynamic seals, but also has relatively high costs in terms of rotation control. And making the spray pipe feed increases the length of the feeding pipeline of the machine. In addition, there are also disadvantages in the layout and space utilization of the equipment. Summary of the Utility Model
[0004] To solve the above problems, the utility model provides a zinc spraying device for the inner pipe of a pipeline. By rotatably placing the pipeline (ductile iron pipe) on a movable moving seat and moving along the nozzle, mechanized zinc spraying operation is realized.
