Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation pipes, in particular to a rust-free and anti-corrosion thermal insulation pipe structure. Background Art

[0002] Insulated pipe is the abbreviation of insulated pipe. Insulated pipe is used for the transportation of liquid, gas and other media. It is used in petroleum, chemical, aerospace, hot spring, military, central heating, central air conditioning, municipal and other fields. Insulated pipe needs to be treated with anti-corrosion and anti-rust during the production process. Anti-corrosion and anti-rust treatment can protect the pipe from corrosion and damage, thereby extending the service life of the pipe.

[0003] The general anti-corrosion and anti-rust treatment is to spray an anti-corrosion layer and an anti-rust layer on the surface of the insulated pipe, so that a dense protective film is formed on the surface of the insulated pipe to isolate air and moisture, thereby effectively preventing the corrosion of the pipe. However, during the use of the insulated pipe, the flowing medium will contain impurities. These impurities adhere to the inner wall of the insulated pipe for a long time, which will also cause corrosion of the inner wall of the insulated pipe.

[0004] Therefore, we have made improvements to this and proposed a rust-free, anti-corrosion and thermal insulation pipe structure. Utility Model Content

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figures 1 to 4 As shown, the utility model is a rust-free and anti-corrosion thermal insulation pipe structure, including a thermal insulation pipe body 1, the thermal insulation pipe body 1 is composed of a thermal insulation layer 2, an anti-rust layer 3 and an anti-corrosion layer 4, the anti-rust layer 3 and the anti-corrosion layer 4 each have two layers, and the thermal insulation layer 2 is respectively located between the two anti-corrosion layers 4, and the two anti-rust layers 3 are respectively located on the side of the two anti-corrosion layers 4 away from the thermal insulation layer 2.

[0023] By providing the heat-insulating layer 2, the anti-rust layer 3 and the anti-corrosion layer 4, the heat-insulating pipe body 1 can be heat-insulated, rust-proof and anti-corrosion-proof, thereby extending its service life.

[0024] Two limit blocks 8 are fixed inside the insulation pipe body 1, and a fixed disk 11 is arranged on the limit blocks 8, and a threaded rod 5 is rotatably arranged in the middle of the side of the fixed disk 11 away from the limit blocks 8, and a connecting disk 7 is threadedly connected to the threaded rod 5. A plurality of cleaning blocks 6 are evenly arranged on the side wall of the connecting disk 7 along the circumferential direction, and the side of the cleaning block 6 away from the connecting disk 7 is slidably connected to the inner wall of the insulation pipe body 1. The cleaning blocks 6 can clean the wet impurities attached to the insulation pipe body 1, so that the inner wall of the insulation pipe body 1 is kept clean, and the insulation pipe body 1 is prevented from rusting due to the long-term presence of impurities. Specifically, during cleaning:

[0025] The fixing plate 11 is placed inside the heat-insulating pipe body 1 and is pressed against the limit block 8. At this time, the cleaning block 6 is located inside the heat-insulating pipe body 1, so that the threaded rod 5 rotates. The rotation of the threaded rod 5 causes the cleaning block 6 to slide along the inner wall of the heat-insulating pipe body 1. The cleaning block 6 is pressed against the inner wall of the heat-insulating pipe body 1, so that it can play a cleaning role during the movement.

[0026] The inner wall of the insulation pipe body 1 is provided with the same number of slide groove areas as the cleaning blocks 6 (not shown in the figure), and the surface of the cleaning block 6 is provided with raised areas matching the slide groove areas (not shown in the figure). Before the cleaning block 6 starts to move, the raised areas on the cleaning block 6 match the slide groove areas on the inner wall of the insulation pipe body 1.

[0027] A clamping block 10 is fixedly connected to one side of the fixed disk 11 facing the limit block 8, and a clamping slot 9 is provided on the limit block 8, and the clamping block 10 is clamped with the clamping slot 9. By clamping the clamping block 10 on the fixed disk 11 with the clamping slot 9 on the limit block 8, a limiting effect can be achieved.

[0028] The cleaning block 6 is made of polyurethane cleaning cotton, which can play a better cleaning role.

[0029] One end of the threaded rod 5 is fixedly connected with a handle 12, and the handle 12 is located outside the insulation pipe body 1. The threaded rod 5 can be rotated by rotating the handle 12, so that the cleaning block 6 moves to clean the inner wall of the insulation pipe body 1.

[0030] A plurality of fixing grooves 14 are evenly arranged on the side wall of the connection disk 7 along the circumferential direction, and one end of the cleaning block 6 is clamped in the fixing groove 14.

A plurality of mounting holes are evenly provided on the connecting plate 7 along the circumferential direction, and the mounting holes penetrate the fixing groove 14. The mounting holes are fixed with fastening bolts 13. When installing, the cleaning block 6 is first clamped in the fixing groove 14, and then the cleaning block 6 is fixed to the connecting plate 7 by the fastening bolts 13 using existing tools. When disassembling, the fastening bolts 13 are first removed, and then the cleaning block 6 is removed.

[0032] During operation, the fixed disk 11 is in contact with the limit block 8, and the handle 12 is turned to drive the threaded rod 5 to rotate, so that the cleaning block 6 can move along the inner wall of the insulation pipe body 1. During the movement, the cleaning block 6 can wipe off the moist impurities attached to the inner wall of the insulation pipe body 1, so that the inner wall of the insulation pipe body 1 remains clean, thereby preventing it from rusting. After cleaning, the fixed disk 11 and the threaded rod 5 thereon can be removed from the insulation pipe body 1, and the cleaning block 6 and the connecting disk 7 can be detachably installed to facilitate its replacement.
