Description

Technical Field

[0001] The present invention relates to the technical field of pipeline spraying, and more particularly to a glass-lined anti-corrosion pipeline spraying device. Background Art

[0002] In numerous industrial sectors, such as the chemical, petroleum, and electric power industries, pipelines serve as crucial vehicles for transporting various media, making their corrosion resistance crucial. Metal pipelines are susceptible to surface corrosion due to chemical or electrochemical reactions when in contact with surrounding media. This not only shortens the pipeline's service life but can also pose safety risks. Glass-lined anti-corrosion technology is gaining increasing attention due to its corrosion resistance, resistance to aging, and high temperature resistance.

[0003] However, the existing glass-lined anti-corrosion pipe spraying equipment still has many shortcomings in practical applications. For example, traditional spraying equipment needs to be constructed on the inner and outer walls in sequence during spraying, and it is necessary to wait until one side is sprayed before the other side. There is a significant process interval, which greatly reduces the spraying efficiency.

[0004] In addition, traditional spraying equipment does not have an anti-overflow mechanism, which causes powder to overflow from both ends of the pipe and float in the air during the spraying process. This not only wastes resources, but also the paint powder floating in the air can easily be accidentally inhaled by workers, thus affecting their health.

[0005] Based on this, the present invention designs a glass-lined anti-corrosion pipeline spraying equipment to solve the above problems. Summary of the Invention

The setting of the sliding grooves 28, sliders 1 29 and sliders 2 30 makes the mounting plate 11 and the lifting block 17 more stable during the lifting process.

[0037] See also Figure 8 The limiting parts are plug-in plates 31 that penetrate and are plugged into the two U-shaped plates 2. There are two groups of plug-in plates 31, and the number of plug-in plates 31 in each group is two. The upper plate surface of one group of plug-in plates 31 is against the lower plate surface of the mounting plate 11, and the upper plate surface of the other group of plug-in plates 31 is against the bottom of the lifting block 17.

[0038] See also Figure 5 An annular dust cover 32 is provided on the inner surface of the annular dust cover 3, and dust collection holes 33 are evenly opened on the inner side of the annular dust cover 32. The bottom of the annular dust cover 32 is connected to a dust collection pipe 34, and one end of the dust collection pipe 34 passes through the annular platform 3. One end of the dust collection pipe 34 is connected to an air pump, and the air outlet end of the air pump is connected to a dust collection box (not shown in the figure) through a pipeline.

[0039] See also Figure 5An annular groove 35 is provided on the top of the annular platform 3, and an annular plate 36 is fixedly installed on the lower plate surface of the annular placement plate 4. Steel balls 37 are evenly arranged on the bottom of the annular groove 35. The annular plate 36 is inserted into the annular groove 35 and contacts the outer surface of the steel balls 37. The steel balls 37 reduce friction, making the pipeline rotate more smoothly and improving the service life of the annular placement plate 4.

[0040] The working principle of the present invention is as follows: the first step is to place the pipe to be sprayed on the annular placement plate 4, start the dual-axis motor 8, and the dual-axis motor 8 drives the two screw rods 9 to rotate. Since the two limit blocks 10 are respectively threaded on the two screw rods 9, and the limit blocks 10 slide in the hollow frame 71, the two limit blocks 10 will move away from each other until they are against the inner wall of the pipe, thereby stably limiting the pipe and also enabling the pipe to be located in the center position of the annular placement plate 4.

[0041] In the second step, the motor 5 is started, and its output shaft drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the annular placement plate 4 to rotate through the cross-shaped connecting plate 7, thereby rotating the pipe placed on the annular placement plate 4. At the same time, the annular plate 36 under the annular placement plate 4 contacts the steel ball 37 in the annular groove 35 of the annular table 3. The steel ball 37 reduces friction and makes the pipe rotate more smoothly.

[0042] The third step is to start the motor 25. Through the operation of the motor 25, one of the winding rollers 20 is driven to rotate. Under the linkage of the sprocket 26 and the chain 27, the other winding roller 20 rotates synchronously. The winding roller 20 rotates to retract and release the wire rope 21. At this time, the mounting plate 11 will move downward under the action of gravity, and the support plate 1 23 drives the mounting plate 11 to move downward in the slide groove 28 of the U-shaped plate 2. The height of the hard pipe 12 and the three-way pipe 14 is adjusted to allow the nozzle 16 to enter the interior of the pipeline and apply the coating. The material enters the tee pipe 14 through the hose 13 and the hard pipe 12, and is then sprayed out from two inclined nozzles 16 to spray the inner wall of the rotating pipe. When the nozzle 16 moves downward to the inside of the pipe, the anti-overflow plate 15 also moves into the pipe, thereby pressing the generated dust downward to prevent the paint from overflowing from the end of the pipe. During the spraying process, the annular dust hood 32 can absorb the powder generated by the spraying through the dust suction hole 33 and the dust suction pipe 34, reducing the powder dispersion, saving resources and protecting the health of workers.

[0043] In the fourth step, also under the action of the retraction and extension of the wire rope 21, the support plate 24 drives the lifting block 17 to move downward in the slide 28, adjusts the height of the discharge pipe 18 and the nozzle 2 181, and aligns the nozzle 2 181 with the outer wall of the pipe. The paint is sprayed out from the nozzle 2 181 through the discharge pipe 18 to spray the outer wall of the rotating pipe.

[0044] In addition, when only the inner wall or outer wall of the pipe needs to be sprayed, the plug plate 31 can be inserted into the U-shaped plate 2 so that the plug plate 31 is against the lower plate surface of the mounting plate 11 or the bottom of the lifting block 17, so that the plug plate 31 supports the mounting plate 11 or the lifting block 17, thereby preventing the mounting plate 11 or the lifting block 17 from moving downward due to the gravity of the mounting plate 11 or the lifting block 17 during the retraction and extension of the wire rope 21.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
