The production process of 3PE anti-corrosion pipes is: electrostatic spraying epoxy powder on the surface of the steel pipe and laterally wrapping adhesive and polyethylene anti-corrosion layer, combining the excellent properties of the three, thus significantly improving the overall quality of the anti-corrosion pipeline.

[0003] The existing cooling technology of 3PE anti-corrosion pipe mainly includes two cooling methods: water cooling and air cooling. For example, the patent publication number CN210700983U provides a 3PE anti-corrosion pipe cooling device, which includes an air cooling part and a water cooling part; the air cooling part includes a cylinder and a blower; the inner wall of the cylinder is fixed with a first mounting plate and a second mounting plate, and a lead screw and a guide slide rod are arranged between the first mounting plate and the second mounting plate; the lead screw is threadedly connected to the nut conversion block, and the blower is arranged on the nut conversion block, and moves back and forth along the axial straight line of the cylinder under the drive of the nut conversion block. By setting up the air cooling part, the anti-corrosion pipe is preliminarily cooled, avoiding the generation of water ripples, grooves, water impact points and dark spots caused by the anti-corrosion pipe being directly sprayed with water under high temperature.

[0004] Based on the above search, combined with the prior art, it is found that the air-cooling method of the blower used in the prior art similar to the above disclosed anti-corrosion pipe cooling device still has the problem of excessive impact of local airflow on the pipe causing surface deformation when blowing air, and after subsequent water cooling, a large amount of water stains are attached to the surface of the pipe, and it cannot be stored directly. Therefore, a 3PE anti-corrosion pipe cooling device is proposed to improve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example: Reference Figure 1-3 The 3PE anti-corrosion pipe cooling device shown comprises a base 1 , a pre-cooling mechanism 2 , a water cooling mechanism 3 and a wiping mechanism 5 .

[0029] Among them, regarding the pre-cooling mechanism 2, specifically, as Figure 2As shown, the pre-cooling mechanism 2 includes an air pump 21, an air guide ring 23 and a plurality of air suction nozzles 24 evenly installed on the inner wall of the air guide ring 23. The air pump 21 is installed on the side end of the base 1. The air guide ring 23 and the base 1 are fixed by an air guide pipe 22, and the air pump 21 is fixedly connected to the air guide ring 23 through the air guide pipe 22.

[0030] When the pipeline passes through the air guide ring 23, the air pump 21 is used to suck air through the air guide pipe 22, the air guide ring 23 and the air suction nozzle 24 to remove the hot air emitted around the pipeline, which is convenient for the pipeline to quickly dissipate heat. Compared with air blowing cooling, the air suction cooling method in this scheme is not easy to cause local stress deformation on the pipeline surface.

[0031] Among them, regarding the water cooling mechanism 3, specifically, Figure 2 As shown, a water collecting tank 101 is provided in the middle part of the base 1, and the water cooling mechanism 3 is installed on the inner side of the water collecting tank 101. The water cooling mechanism 3 includes a circulating water pump 31, a refrigerator 32, a water guide ring 34 and a plurality of nozzles 35 evenly installed on the inner wall of the water guide ring 34. The circulating water pump 31 and the refrigerator 32 are both installed at the inner bottom end of the water collecting tank 101, and the two are connected by a connecting pipe. A water guide pipe 33 is fixed between the water guide ring 34 and the inner wall of the water collecting tank 101. The circulating water pump 31 is connected to the water guide ring 34 through the water guide pipe 33, and the water guide ring 34 is coaxially arranged with the air guide ring 23.

[0032] Based on the coordinated arrangement of the above structure, the circulating water pump 31 is used to pump the water in the water collecting tank 101 into the water guide ring 34, and the cooling water is evenly sprayed on the surface of the pipeline through the nozzle 35 to water-cool the pipeline.

[0033] Among them, about the wiping mechanism 5, specifically, as Figure 2 It is shown that the wiping mechanism 5 is installed at the upper end of the base 1 and is located on the side of the water cooling mechanism 3 away from the pre-cooling mechanism 2. The wiping mechanism 5 includes a fixed ring 53 and absorbent cotton 55. The fixed ring 53 is installed at the upper end of the base 1, and the absorbent cotton 55 is installed on the inner ring of the fixed ring 53. The fixed ring 53 is coaxially arranged with the water guide ring 34. The pipe after water cooling continues to move toward one side of the wiping mechanism 5, and the absorbent cotton 55 is used to absorb water stains on the surface of the pipe, so as to facilitate direct storage after cooling.

[0034] In order to adapt to pipes of different diameters, the wiping mechanism 5 also includes an air pump 51 and an elastic membrane 54. The air pump 51 is installed at the side end of the base 1. An air guide pipe 52 is fixed between the fixed ring 53 and the base 1. The fixed ring 53 is set to be hollow, and the air pump 51 is connected to the fixed ring 53 through the air guide pipe 52. An annular opening is set on the inner circumference of the fixed ring 53. The elastic membrane 54 is fixed at the annular opening, and the absorbent cotton 55 is fixed on the outer surface of the elastic membrane 54.

[0035] Based on the above structure, for pipes with smaller diameters, an air pump 51 can be used to inflate air into the fixed ring 53 through the air guide tube 52, so that the elastic membrane 54 bulges outward, thereby bringing the absorbent cotton 55 to fit the pipe and wipe the moving pipe.

[0036] In order to reduce the wiping burden of the wiping mechanism 5, a pre-dewatering mechanism 4 is arranged between the water cooling mechanism 3 and the wiping mechanism 5. The pre-dewatering mechanism 4 is installed at the upper end of the base 1, and the structure of the pre-dewatering mechanism 4 is consistent with the structure of the pre-cooling mechanism 2, which will not be repeated here. The pre-dewatering mechanism 4 can be used to absorb most of the water stains attached to the surface of the pipe.

[0037] The working principle of the utility model is as follows: when the pipeline passes through the air guide ring 23, the air pump 21 is used to suck air through the air guide pipe 1 22, the air guide ring 23 and the air suction nozzle 24 to remove the hot air emitted around the pipeline, so as to facilitate the rapid heat dissipation of the pipeline and realize the pre-cooling of the pipeline. Compared with the blowing cooling, the air suction cooling method in this scheme is not easy to cause local stress deformation on the pipeline surface; then the circulating water pump 31 is used to suck the water in the water collecting tank 101 into the water guide ring 34, and the cooling water is evenly sprayed on the pipeline surface through the nozzle 35 to water-cool the pipeline; the pipeline after water cooling continues to move toward one side of the wiping mechanism 5, and the pre-water removal mechanism 4 is used to absorb most of the water stains attached to the pipeline surface, and then the absorbent cotton 55 is used to absorb the water stains on the pipeline surface, so as to facilitate direct storage after cooling. For pipelines with smaller diameters, the blowing pump 51 can be used to inflate the fixed ring 53 through the air guide pipe 2 52, so that the elastic membrane 54 bulges outward, thereby bringing the absorbent cotton 55 to fit the pipeline and wipe the moving pipeline.
