Description

Technical Field

[0001] The utility model relates to a pipe cleaning device, in particular to a high-density polyurethane foam pipe cleaning device used in the field of pipeline cleaning. Background Art

[0002] After long-distance oil and natural gas pipelines have been running for a period of time, there will be liquid accumulation, dust, wax and other impurities in the pipelines. The deposition of these impurities in the pipelines will affect the equivalent diameter of the pipelines and reduce the transportation efficiency of the pipelines. In order to ensure the efficient operation of the pipelines, long-distance pipelines must be cleaned regularly.

[0003] Long-distance pipelines need to be cleaned regularly. Mechanical pipe cleaners are generally used for routine cleaning. The connecting parts of mechanical pipe cleaners are generally made of high-strength carbon steel. The overall rigidity of the pipe cleaners is extremely strong. Mechanical pipe cleaners are very prone to getting stuck during pipe cleaning operations. Once stuck, the position of the pipe cleaner cannot be determined and the blockage cannot be cleared in time, which will cause great losses to pipeline transportation. Utility Model Content

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that when cleaning long-distance pipelines, mechanical pipe cleaners are generally made of high-strength carbon steel, and are very prone to getting stuck during the cleaning process. Once stuck, the position of the pipe cleaner cannot be determined and the blockage cannot be cleared in time, which will cause great losses to pipeline transportation.

[0005] In order to solve the above problems, the utility model provides a high-density polyurethane foam pipe cleaner, including an outer shell, the outer surface of the outer shell is coated with a wear-resistant coating, the inner bottom wall of the outer shell is fixedly connected with an embedded steel plate, the inner wall of the outer shell is fixedly connected with a foam core material, the upper end of the embedded steel plate is fixedly connected with a traction rope, the upper end of the traction rope is fixedly passed through the foam core material and the outer shell in turn and is fixedly connected with a fixing ring, the lower end of the outer shell is fixedly connected with a mounting ring, the upper end of the mounting ring is fixedly passed through a plurality of heating rods, a fixing plate is also fixedly connected between the outer shell and the mounting ring, a limiting groove is cut on the surface of the fixing plate, an umbrella-shaped scraper is movably embedded in the limiting groove, and a plurality of springs are fixedly connected to the inner wall of the limiting groove.

[0006] In the above-mentioned high-density polyurethane foam pipe cleaner, the pipe cleaner itself has the characteristics of tear resistance and high elasticity, and is not prone to jamming during use, thereby effectively reducing the jamming of pipeline cleaning and reducing the risk of pipe cleaning operations, thereby effectively solving the problem of large-scale accumulation of impurities in long-distance pipelines affecting the pipeline's transportation capacity.

[0007] As a further improvement of the present application, the foam core material and the shell are both made of polyurethane foam fully coated spherical material, and the density of the polyurethane foam fully coated spherical material is 220 kilograms per cubic meter.

[0008] As another improvement of the present application, the heating rods are distributed in a ring array around the central axis of the shell, and the mounting ring is made of an elastic high-temperature resistant material.

[0009] As another improved supplement of the present application, the springs are distributed in an annular array around the central axis of the fixed plate, and the other end of the spring is fixedly connected to the inner annular surface of the umbrella-shaped scraper.

[0010] As another improvement of the present application, grooves are chiseled at the corners of the umbrella-shaped scraper, and the thickness of the umbrella-shaped scraper is consistent with the depth of the limiting groove.

[0011] As another improved supplement of the present application, the umbrella-shaped scraper includes a plurality of flexible blocks and a plurality of hard blocks respectively and staggeredly fixedly connected to the plurality of flexible blocks, and an elastic pad is fixedly connected to one end of the hard block away from the spring.

[0012] In summary, in actual application, the glass transition temperature of polyester material is 69°C, the softening range is 230-240°C, and the melting point is 255-260°C. It has good fiber-forming properties, mechanical properties, wear resistance, creep resistance, low water absorption and electrical insulation properties, which makes the pipe cleaner tear-resistant and highly elastic. When the pipe cleaner is placed inside the pipeline, the outer surface of the shell fits the inner wall of the pipeline, and the pipe cleaner is pushed to slide into the pipeline through the fixing ring, traction rope and embedded steel plate to perform pipe cleaning operations. The foam core material and the shell are both elastic, and are not prone to blockage during pipe cleaning operations, thereby effectively reducing the situation of pipeline cleaning blockage and reducing the risk of pipe cleaning operations, thereby effectively solving the problem of large-scale accumulation of impurities in long-distance pipelines affecting the pipeline transportation capacity.

[0023] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0024] The first implementation method:

[0025] Figure 1 and Figure 2 It is shown that: a high-density polyurethane foam pipe cleaner comprises an outer shell 1, the outer surface of the outer shell 1 is coated with a wear-resistant coating, the inner bottom wall of the outer shell 1 is fixedly connected with an embedded steel plate 2, the inner wall of the outer shell 1 is fixedly connected with a foam core material 3, the upper end of the embedded steel plate 2 is fixedly connected with a traction rope 4, the upper end of the traction rope 4 is fixedly passed through the foam core material 3 and the outer shell 1 in sequence and is fixedly connected with a fixing ring 5, the embedded steel plate 2, the traction rope 4 and the fixing ring 5 are convenient for limiting the position of the pipe cleaner, thereby pushing the pipe cleaner to move inside the pipeline, and the pipe cleaner is also positioned during use to facilitate knowing the position of the pipe cleaner, the foam core material 3 and the outer shell 1 are both made of polyurethane foam fully coated ball material, the density of the polyurethane foam fully coated ball material is 220 kilograms per cubic meter, and the high-density polyurethane foam fully coated ball material makes the pipe cleaner have the characteristics of tear resistance and high elasticity, and it is not easy to cause pipeline blockage during use.

[0026] When in use, the polyester material has a glass transition temperature of 69°C, a softening range of 230-240°C, and a melting point of 255-260°C. It has good fiber-forming properties, mechanical properties, wear resistance, creep resistance, low water absorption, and electrical insulation properties, so that the pipe cleaner has tear resistance and high elasticity. When the pipe cleaner is placed inside the pipeline, the outer surface of the outer shell 1 fits with the inner wall of the pipeline, and the pipe cleaner is pushed to slide into the pipeline through the fixing ring 5, the traction rope 4, and the embedded steel plate 2 to perform the pipe cleaning operation. The foam core material 3 and the outer shell 1 are both elastic, and are not prone to blockage during the pipe cleaning operation, thereby effectively reducing the situation of pipeline cleaning blockage and reducing the risk of pipe cleaning operations, thereby effectively solving the problem of large-scale accumulation of impurities in long-distance pipelines affecting the pipeline transportation capacity.

[0027] The second implementation method:

[0028] Based on the first embodiment, this embodiment adds a mounting ring 6 and a heating rod 7, and the rest of the parts are consistent with the first embodiment.

[0029] Figure 3 and Figure 4 It is shown that: the lower end of the outer shell 1 is fixedly connected with a mounting ring 6, and the upper end of the mounting ring 6 is fixedly penetrated by a plurality of heating rods 7, the heating rods 7 can increase the surface temperature of the mounting ring 6, thereby softening the wax material on the inner wall of the pipeline, the heating rods 7 are distributed in a ring array around the central axis of the outer shell 1, and the mounting ring 6 is made of elastic high-temperature resistant material.

[0030] When in use, the temperature of the mounting ring 6 can be increased by starting the heating rod 7. When the mounting ring 6 contacts the inner wall of the pipeline, the wax deposited material on the inner wall of the pipeline can be softened, thereby facilitating its cleaning.

[0031] The third implementation method:

[0032] Based on the second embodiment, this embodiment adds a fixing plate 8, a limiting groove 9, an umbrella-shaped scraper 10, a spring 11 and a groove 12, and the rest of the parts are consistent with the first embodiment.

[0033] Figure 5 , Figure 6 , Figure 7 and Figure 8 It is shown that a fixing plate 8 is fixedly connected between the housing 1 and the mounting ring 6, a limiting groove 9 is cut on the surface of the fixing plate 8, an umbrella-shaped scraper 10 is movably embedded in the limiting groove 9, a plurality of springs 11 are fixedly connected to the inner wall of the limiting groove 9, the expansion and contraction of the springs 11 facilitates the movement of the umbrella-shaped scraper 10, the springs 11 are distributed in an annular array around the central axis of the fixing plate 8, the other end of the spring 11 is fixedly connected to the inner annular surface of the umbrella-shaped scraper 10, a groove 12 is cut at the corner of the umbrella-shaped scraper 10, the groove 12 facilitates the deformation of the umbrella-shaped scraper 10 to fit the fixing plate 8 inwardly, The thickness of the umbrella-shaped scraper 10 is consistent with the depth of the limiting groove 9. The umbrella-shaped scraper 10 includes a plurality of flexible blocks 101 and a plurality of hard blocks 102 which are respectively staggered and fixedly connected to the plurality of flexible blocks 101. The hard block 102 is fixedly connected to an elastic pad 103 at one end away from the spring 11. When the umbrella-shaped scraper 10 is squeezed, the elastic pad 103 deforms inward to squeeze the hard block 102, causing the spring 11 to shrink and move inward. At the same time, the flexible block 101 is deformed, thereby reducing the overall diameter of the umbrella-shaped scraper 10, making it easier to clean pipes of different diameters.

[0034] When in use, after the heating rod 7 softens the waxy material in the pipe, the waxy material is scraped away by the umbrella-shaped scraper 10. When the inner diameter of the pipe becomes narrower, the umbrella-shaped scraper 10 is squeezed and moves inward, causing the spring 11 to contract inward, thereby improving the practicality of the umbrella-shaped scraper 10.

[0035] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
