Abstract
Description
Technical Field
[0001] This utility model relates to the field of crude oil processing equipment technology, and more specifically, it relates to a heating device for crude oil pipelines. Background Technology
[0002] Crude oil is a viscous, dark brown liquid, often referred to as the "blood of industry." It is composed of a mixture of various hydrocarbons, primarily alkanes, cycloalkanes, and aromatics, and is a non-renewable fossil fuel. Crude oil is a complex and vital natural resource; its physical and chemical properties make it irreplaceable in industrial production and daily life.
[0003] In the petrochemical industry, crude oil transportation relies primarily on pipeline systems. The stability of pipeline connections is crucial for the safe operation of the entire transportation system. Unstable pipeline connections can not only lead to crude oil leaks, wasting resources and causing environmental pollution, but can also trigger safety accidents such as fires or explosions, threatening the safety of personnel and facilities.
[0004] In existing technologies, pipe connections typically employ flanges, threads, or welding. Over long-term use, these connections may loosen, wear, or crack due to factors such as temperature variations, pressure fluctuations, and material fatigue, increasing the risk of leakage. These connection problems are particularly pronounced in harsh external environments (such as those with high temperatures, high pressures, or corrosive media).
[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a heating device for crude oil pipelines. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heating device for crude oil pipelines.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a heating device for crude oil pipelines, comprising a heating pipeline body, a telescopic pipeline body disposed within the heating pipeline body, an oil inlet port disposed at one end of the telescopic pipeline body, and a fixing component for fixing the crude oil pipeline disposed outside the oil inlet port;
[0008] The fixing component includes an installation port, which is a hollow ring shape, and a clamping mechanism is provided on the inner wall of the installation port. A protrusion is provided above the installation port, and a control mechanism for controlling the clamping mechanism to open and close is provided inside the protrusion.
[0009] The clamping mechanism includes a second gear disposed in the mounting port, the second gear having a plurality of limiting grooves, and a limiting post disposed in each of the limiting grooves;
[0010] The control mechanism includes a first gear disposed within the protrusion, the first gear meshing with a second gear, and a screw disposed at the axis of the first gear.
[0011] Furthermore, the oil inlet port is provided with several flange interfaces around the perimeter of the crude oil pipeline.
[0012] Furthermore, a circular groove is provided at the bottom of the installation port, and the limiting post is located in the circular groove. One end of the connecting plate is connected to the outside of the limiting post, and the other end of the connecting plate is connected to an arc-shaped clamp for fixing the crude oil pipeline.
[0013] Furthermore, the other end of the telescopic pipe body is provided with an oil outlet port for crude oil discharge.
[0014] Furthermore, the circular groove is provided with a sliding groove corresponding to the number of connecting plates, and the connecting plates are slidably connected within the sliding groove.
[0015] Furthermore, a mounting base is provided at the bottom of the heating pipe body, a telescopic cylinder is provided on the heating pipe body, a connecting block is provided at the extended end of the telescopic cylinder, and the connecting block is provided on the telescopic pipe body.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] In this invention, by setting a clamping mechanism and a control mechanism, the crude oil pipeline is connected to the oil inlet port. Then, the clamping mechanism is closed by rotating the control mechanism, thereby fixing the crude oil pipeline. The advantage of this is that when the connection between the original pipeline opening and the oil inlet port is corroded due to natural environmental reasons, it may become loose. However, due to the presence of the fixing component, the connection between the crude oil pipeline and the oil inlet port will not become loose under the action of the fixing component. This can effectively prevent crude oil leakage and reduce energy waste.
[0018] In this invention, a telescopic cylinder is installed on the heating pipe body. The telescopic cylinder is connected to the telescopic pipe body, and the length of the telescopic pipe body can be changed by the action of the telescopic cylinder. The advantage of this is that after the mounting base is fixed, when connecting with crude oil pipes of different lengths, the length of the telescopic pipe body can be changed at will under the action of the telescopic cylinder, which makes it convenient for workers to connect the pipes and improves the connection efficiency.

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0027] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs. Example
[0028] Please see Figures 1 to 4This utility model provides a heating device for crude oil pipelines, including a heating pipe body 1, a mounting base 6 at the bottom of the heating pipe body 1, a telescopic cylinder 5 on the heating pipe body 1, a connecting block 7 at the extended end of the telescopic cylinder 5, and the connecting block 7 is mounted on the telescopic pipe body 2. The telescopic cylinder 5 is connected to the telescopic pipe body 2, and the length of the telescopic pipe body 2 can be changed by the action of the telescopic cylinder 5. Since the length of the telescopic pipe body 2 can be changed at will under the action of the telescopic cylinder, it is convenient for workers to connect the pipeline. The telescopic pipe body 2 is installed inside the heating pipe body 1. One end of the telescopic pipe body 2 is provided with an oil outlet port 3 for crude oil discharge, and the other end of the pipe body is provided with an oil inlet port 18. Several flange interfaces for connecting with the crude oil pipeline are arranged around the outside of the oil inlet port 18, and a fixing component for fixing the crude oil pipeline is arranged outside the oil inlet port 18.
[0029] The fixing component includes an installation port 4, which is a hollow annular shape. A clamping mechanism is provided on the inner wall of the installation port 4. A protrusion 17 is provided above the installation port 4. A control mechanism for controlling the opening and closing of the clamping mechanism is provided in the protrusion 17. The clamping mechanism includes a second gear 10 provided in the installation port 4. The second gear 10 is provided with several limiting grooves 11. A limiting post 12 is provided in a single limiting groove 11. A circular groove 13 is provided at the bottom of the installation port 4. The limiting post 12 is located in the circular groove 13. One end of a connecting plate 14 is connected to the outside of the limiting post 12. The other end of the connecting plate 14 is connected to an arc-shaped clamping plate 15 for fixing the crude oil pipeline. A sliding groove 16 corresponding to the number of connecting plates 14 is provided in the circular groove 13. The connecting plates 14 slide in the sliding groove 16. The purpose of the arc-shaped clamping plate 15 is to better fit the surface of the crude oil pipeline when clamping it, so that the crude oil pipeline can be clamped more stably.
[0030] The control mechanism includes a first gear 9 disposed in the protrusion, which meshes with a second gear 10. A screw 8 is disposed at the shaft of the first gear 9. When the first gear 9 is rotated, the first gear 9 drives the second gear 10 to rotate, thereby causing the limiting post 12 in the limiting groove 11 on the second gear 10 to move, and then the arc-shaped clamping plate 15 to close. The purpose of the control mechanism here is to facilitate the opening and closing control of the clamping mechanism, and to more conveniently achieve the clamping and fixing of the crude oil pipeline.
[0031] Working principle: The crude oil pipeline opening is aligned with the inlet port 18 and inserted, and then the two are connected by a flange. If the mounting base 6 is located far from the crude oil pipeline, the telescopic pipe body 2 can be stretched by the telescopic cylinder 5, allowing the crude oil pipeline opening to enter the inlet port 18. Then, the screw 8 is rotated, which drives the first gear 9 in the protrusion 17 to rotate. Since the second gear 10 is meshed with the first gear 9, the second gear 10 rotates along with it, thereby causing the limiting groove 11 to drive the limiting post 12 to move. A connecting plate 14 is provided inside and outside the circular groove 13. The connecting plate 14 is in the sliding groove 16 inside the circular groove 13. Therefore, when the second gear 10 rotates, it drives the limiting post 12 to move towards the crude oil pipeline, so that the arc-shaped clamp 15 fits against the surface of the crude oil pipeline. In this way, when the crude oil pipeline is corroded due to natural environmental reasons, the crude oil will not loosen when it enters the heating pipe body 1 inside the crude oil pipeline due to the presence of the fixing component. Thus, the crude oil is heated under the action of the heating pipe body 1, and the treated crude oil flows out from the oil outlet 3.
