Description

TECHNICAL FIELD

[0001] The utility model relates to oil pipeline cleaning technical field, concretely is a kind of ball of silk gourd core structure for pipeline cleaning. BACKGROUND

[0002] Oilfield gathering and transportation pipeline network is an important infrastructure for oil exploitation and transportation, which is large in scale and complex in structure, covering the whole process from oil well to treatment plant, to storage and transportation point. Many of these pipelines have never been subjected to systematic cleaning since they were put into operation due to high maintenance cost and complex operation. With the passage of time, crude oil continues to flow in the pipeline, and a large amount of oil dirt, silt, wax and other types of deposits inevitably accumulate. The accumulation of these deposits not only significantly reduces the flow efficiency of the pipeline and increases the energy consumption of transportation, but also poses a serious threat to the safe operation of the pipeline in the long run, such as causing the inner diameter of the pipeline to shrink, the pressure loss to increase, and even the blockage accident to occur.

[0003] Traditional cleaning tools such as hard ball and scraper can remove some deposits in the pipeline to some extent, but their inherent defects cannot be ignored. Hard ball is rigid and non-deformable, which can easily scratch or damage the inner wall of the pipeline during cleaning, especially when the inner wall of the pipeline is corroded, worn or irregularly shaped. The scraper tool has better effect on removing deposits, but when used in long-distance pipeline, the scraper is easy to accumulate too much impurities due to the large amount of deposits, which may cause blockage and affect the smooth progress of cleaning operation. Therefore, it is particularly important to develop a cleaning ball that can effectively remove deposits without blocking the pipeline. SUMMARY

[0004] In view of the problem that the existing cleaning tool is not convenient for cleaning long-distance pipeline, the utility model provides a ball of silk gourd core structure for pipeline cleaning.

[0022] Further, the cross-sectional area of the mesh strip of the reinforcing mesh is greater than the cross-sectional area of the filament strip, so that the strength and stability of the outer shell can be guaranteed.

[0023] Further, the inner shell thickness is greater than the outer shell thickness so that the cleaning ball can maintain a certain flexibility while maintaining structural strength, facilitating movement in the pipeline.

[0029] The utility model will be further described in detail below in combination with specific embodiments, which are an explanation of the utility model rather than a limitation.

[0030] The utility model discloses a cleaning ball with the structure of the sponge gourd pulp for pipelines, referring to Figure 1 , comprising a sphere in a hollow form, and the sphere is in the form of the sponge gourd pulp porous structure, which not only increases the contact area with the inner wall of the pipeline, but also enables the cleaning liquid to penetrate and act on the dirt more uniformly, thereby significantly improving the cleaning efficiency.

[0031] The sphere is made of an elastic material, and in the embodiment, the material of the sphere structure is a composite material comprising a bio-based material, a degradable plastic and a reinforcing fiber material. The bio-based material is a material manufactured by biological, chemical and physical means from the contents of crops, trees and other plants and their residues. The reinforcing fiber material is one or a mixture of carbon fiber or glass fiber, which not only endows the cleaning ball with excellent cleaning performance, but also embodies the concept of environmental protection and sustainable development.

[0032] The diameter of the sphere is greater than the pipe diameter of the pipeline by 1-2 mm, so that the cleaning ball can generate a certain friction in the pipeline, thereby better removing dirt and blockages.

[0033] The ball comprises an inner shell 1 and an outer shell 2 from inside to outside, wherein the thickness of the inner shell 1 is greater than the thickness of the outer shell 2, so as to ensure that the cleaning ball has sufficient structural strength and flexibility, so that the cleaning ball can adapt to the bending and turning in the pipeline and help the overall cleaning of the pipeline. In addition, the sum of the thicknesses of the outer shell 2 and the inner shell 1 is less than the radius of the ball, and in the embodiment, the sum of the thicknesses of the outer shell 2 and the inner shell 1 is one third of the radius, so as to ensure that the cleaning ball will not be completely deformed or collapsed when being extruded or subjected to external force, and the cleaning effect is maintained.

[0034] The inner shell 1 comprises a plurality of single bodies spliced with each other, and each single body is formed by winding a filament structure. In the embodiment, the single bodies are formed by winding the filament structures between adjacent single bodies, and the plurality of single bodies can disperse stress when the cleaning ball is subjected to pressure, so as to avoid damage to the cleaning ball. Compared with the sheet single body, the single body formed by winding the filament structure has a larger surface area, so that the contact area between the cleaning ball and the inner wall of the pipeline is increased, and the cleaning effect is improved.

[0035] The outer shell 2 is a reinforcing grid, and the reinforcing grid is an irregular grid formed by winding a grid strip. The cross-sectional area of the grid strip of the reinforcing grid is greater than that of the filament strip, so as to ensure the strength and stability of the outer shell 2.

[0036] The ball is processed by a 3D printing process, so that the shape and size of the cleaning ball can be accurately controlled, and the ball can be customized according to actual needs, such as adjusting the size, shape and material of the ball, so as to meet the cleaning needs of different pipelines.

[0037] The use principle of the cleaning ball with the loofah structure for pipelines is as follows: when the cleaning ball with the loofah structure of the composite material enters the oil pipeline, the porous structure begins to adsorb and wrap the impurities such as deposits and oil stains on the inner wall of the pipeline. With the movement of the cleaning ball in the pipeline, the surface of the cleaning ball is in close contact with the inner wall of the pipeline, and the elasticity of the fiber and the adsorption force of the porous structure are utilized to gradually peel off the deposits from the inner wall of the pipeline. When the cleaning ball moves to the outlet of the pipeline, the dirt carried by the cleaning ball is discharged from the pipeline. At this time, the cleaning ball can be cleaned and reused.

[0038] The design of the loofah structure of the composite material avoids the risk of scratching the inner wall of the pipeline by traditional cleaning tools, and realizes gentle and effective cleaning. The application of the porous structure and the high oil absorption material makes the cleaning ball have excellent cleaning ability for the deposits such as oil stains. The use of bio-based materials and degradable plastics as the matrix of the composite material makes the cleaning ball naturally degradable after being discarded, reduces environmental pollution; at the same time, the addition of the reinforcing fiber improves the durability of the material. The reusable feature reduces the cleaning cost; and the cost of the composite material is relatively low, which is conducive to large-scale popularization and application.

[0039] The above merely describes preferred embodiments of the present application, and is not intended to limit the technical solutions of the present application in any way. Those skilled in the art should understand that, without departing from the spirit and principle of the present application, the technical solutions can be modified and replaced in several simple ways, and these modifications and replacements also fall within the protection scope of the claims.
