Description

Technical Field

[0001] This utility model relates to the field of pipeline internal wall corrosion prevention technology, and in particular to a long-distance, large-diameter buried pipeline internal wall rust removal and corrosion prevention device. Background Technology

[0002] Currently, the internal corrosion protection of long-distance, large-diameter pipelines is usually processed in sections at the factory and then transported to the site for unified welding. To extend the service life of the pipeline, the inner wall of the welded large-diameter pipeline needs to be treated with corrosion protection. However, the corrosion protection equipment is large, and the cost of moving it to the site for corrosion protection is high. Secondly, the internal corrosion protection layer of the pipeline is easily damaged after a certain number of years of use, which leads to a shortened service life of the pipeline. If we want to save costs and continue to use the pipeline, we need to remove rust and re-spray anti-corrosion material on the inner wall of the pipeline after a certain period of use. The conventional method requires digging the pipeline out of the ground, cutting it into sections and returning it to the factory for rust removal, then welding it again, and spraying the anti-corrosion coating on site. The above operations involve large investments, long cycles, and many pipeline cutting and welding operations, which can easily damage the pipeline.

[0003] Therefore, there is an urgent need for an integrated device that can perform rust removal and corrosion protection on welded pipes. Utility Model Content

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0031] like Figure 1-6 As shown, a pipe inner wall rust removal and anti-corrosion device includes a vehicle body 1, a laser rust remover 2, and a vacuum cleaner 3. Both the laser rust remover 2 and the vacuum cleaner 3 are mounted on the vehicle body 1. It also includes a two-component sprayer 4 and a rotary spray gun 5. The two-component sprayer 4 is mounted on the vehicle body 1, and one end of the rotary spray gun 5 is connected to the two-component sprayer 4. This integrated vehicle uses the laser rust remover 2 on the vehicle body 1 to remove rust from the inner wall of the pipe, uses the vacuum cleaner 3 to absorb the waste generated during rust removal, and then uses the rotary spray gun 5 to re-spray the inner wall of the pipe with anti-rust treatment. This eliminates the need to dig up and cut the buried pipe for rust removal and anti-corrosion treatment, saving costs and shortening the maintenance time of old pipes.

[0032] The rotary spray gun 5 includes a delivery pipe 51 and a nozzle 52. One end of the delivery pipe 51 is connected to the two-component sprayer 4, and the other end of the delivery pipe 51 is connected to the nozzle 52.
