Description

Technical Field

[0001] This utility model relates to the field of petroleum transportation technology, and in particular to a liquid heating device for petroleum transportation. Background Technology

[0002] Petroleum is a major energy source. It is stored in some areas of the upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. There are two theories about the formation mechanism of petroleum: biogenic sedimentary petroleum and petrochemical petroleum. The former is more widely accepted and believes that petroleum is formed by ancient marine or lake organisms through a long evolutionary process. It is a biogenic sedimentary petroleum and is non-renewable. The latter believes that petroleum is formed from carbon within the Earth's crust and is not related to organisms. It is renewable. Petroleum is mainly used as fuel oil and gasoline. It is also a raw material for many chemical industrial products, such as solutions, fertilizers, pesticides, and plastics.

[0003] When oil is transported inside pipelines, it can solidify due to the heat generated during the flow, which can affect its normal transport. Therefore, heating devices are needed to keep the oil in a liquid state.

[0004] In existing heating devices, oil flows through the inner wall of the device during heating. Over time, the oil will stick to the inside of the pipe, causing blockage and affecting its use. Furthermore, electromagnetic heating can lead to excessively high temperatures and damage to the pipe. Therefore, a liquid heating device for oil transportation is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a liquid heating device for oil transportation, which aims to improve the problem of the inability to clean the inner wall of the heating device in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A liquid heating device for oil transportation includes an outer pipe, an inner pipe fixedly connected to the inner side of the outer pipe, mounting rings fixedly connected to both ends of the outer pipe, an outlet at one end of the outer pipe, an inlet at the other end of the outer pipe, a heating component installed inside the outer pipe, the heating component being located outside the inner pipe, and a cleaning mechanism installed inside the inner pipe.

[0008] The cleaning mechanism includes two ring blocks, which are fixedly connected inside the inner tube. Multiple connecting rods are fixedly connected to the inner side of each ring block. A rotating shaft is fixedly connected between the multiple connecting rods. A fixed rod is fixedly connected to one side of the rotating shaft. Multiple connecting rods are fixedly connected to the outer side of the fixed rods. A scraper is fixedly connected to the other end of the multiple connecting rods.

[0009] As a further description of the above technical solution:

[0010] The heating assembly includes a heating water tank, which is fixedly connected to one side of the outer pipe. A water supply pipe is fixedly connected to one side of the heating water tank. A heating water pipe is provided outside the inner pipe. The other end of the water supply pipe is fixedly connected to one end of the heating water pipe. A return water pipe is fixedly connected to the other side of the heating water tank. The other end of the return water pipe is fixedly connected to the other end of the heating water pipe.

[0011] As a further description of the above technical solution:

[0012] A water pump is installed in the middle of the water pipe, and the water pump is located outside the outer pipe.

[0013] As a further description of the above technical solution:

[0014] A heating coil is provided on the outside of the inner tube, and the heating coil is located between the outer tube and the inner tube;

[0015] As a further description of the above technical solution:

[0016] The mounting ring has multiple circular holes in its center, and the mounting ring is located at both ends of the outer tube.

[0017] As a further description of the above technical solution:

[0018] A rotating rod is fixedly connected to one side of the rotating shaft, and multiple blades are fixedly connected to the outside of the rotating rod;

[0019] As a further description of the above technical solution:

[0021] As a further description of the above technical solution:

[0022] There are two scrapers, which abut against the inside of the inner tube.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by setting a block inside the heating device, fixing the rotating shaft and blades with a ring block, and setting a fixing rod between the two rotating shafts, the blades are driven to rotate by the flowing liquid, and the fixing rod drives the fixing plate to rotate, scraping the inner wall of the inner tube in real time to prevent wax and impurities from depositing and maintain heat transfer efficiency. The blades use the flow of crude oil to drive the rotating rod, realizing automatic cleaning without additional energy consumption. Filtration and cleaning are linked, dynamically scraping off the scale layer, and the filter plate intercepts large particles of impurities, reducing the frequency of downtime for cleaning. This design extends the service life of the device through a self-cleaning mechanism.

[0025] 2. In this utility model, a closed water circulation system is formed by the heating water tank and the heating water pipe. With the help of the water pump, hot water is forced to circulate, so as to achieve uniform heat conduction. The heating coil directly wraps the inner tube for auxiliary electric heating. The dual heat source can quickly increase the temperature of crude oil, prevent low-temperature solidification and blockage of the pipeline, and the heating method can be controlled to reduce pipeline damage.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a liquid heating device for oil transportation, comprising an outer pipe 1, an inner pipe 21 fixedly connected to the inner side of the outer pipe 1, forming a double-layer pipeline structure with the outer pipe 1 and the inner pipe 21, the space between the outer pipe 1 and the inner pipe 21 being used to install the heating device, the inner pipe 21 serving as the main channel for crude oil flow, mounting rings 6 fixedly connected to both ends of the outer pipe 1 for installing the heating device onto the transportation pipeline, an outlet 9 at one end of the outer pipe 1 and an inlet 8 at the other end of the outer pipe 1, both the inlet 8 and the outlet 9 being used to allow oil to flow, with oil entering from the inlet 8 and flowing out from the outlet 9, a heating component installed inside the outer pipe 1, located outside the inner pipe 21, heating the oil with the heating component between the outer pipe 1 and the inner pipe 21 to allow the oil to flow better, and a cleaning mechanism installed inside the inner pipe 21 to clean the inner wall of the inner pipe 21 to prevent blockage;

[0034] The cleaning mechanism includes two ring blocks 14, which are fixedly connected inside the inner tube 21. The cleaning mechanism is mounted inside the inner tube 21 using the two ring blocks 14. Multiple connecting rods 15 are fixedly connected to the inner sides of each ring block 14, and a rotating shaft 16 is fixedly connected between the multiple connecting rods 15. The rotating shaft 16 is mounted inside the ring blocks 14 using the connecting rods 15, providing a prerequisite for the rotation of the cleaning mechanism. A fixed rod 17 is fixedly connected to one side of the rotating shaft 16. The fixed rod 17, mounted via the rotating shaft 16, can rotate inside the heating device. A fixed rod 17 is fixedly connected to the outer side of the fixed rod 17. There are multiple connecting rods 18 located on both sides of the fixed rod 17. The other end of the multiple connecting rods 18 is fixedly connected to a scraper 19. The scraper 19 is fixed by the connecting rods 18, so that the scraper 19 can rotate with the fixed rod 17. There are two scrapers 19, which abut against the inside of the inner tube 21. The two scrapers 19 are used to remove impurities from the inner wall of the inner tube 21. By fixing the ring block 14 inside the heating device, the ring block 14 supports the rotation of other structures. While rotating, the scraper 19 cleans the inner tube 21, avoiding the accumulation of impurities and extending the service life.

[0035] Reference Figure 1 and Figure 3The heating assembly includes a heating water tank 2, which is fixedly connected to one side of the outer pipe 1. The heating water tank 2 contains water, which is heated. A water supply pipe 3 is fixedly connected to one side of the heating water tank 2, allowing the water inside the heating water tank 2 to flow out. A heating water pipe 12 is installed outside the inner pipe 21, used to heat the inner pipe 21 and the oil inside. The other end of the water supply pipe 3 is fixed to one end of the heating water pipe 12, allowing hot water from the heating water tank 2 to flow into the heating water pipe 12. A return water pipe 4 is fixedly connected to the other side of the heating water tank 2, allowing the water to flow out from the other side of the outer pipe 12. Fixedly connected to the other end of the heating water pipe 12, the return water pipe 4 allows the water in the heating water pipe 12 to flow back into the heating water tank 2. A water pump 5 is installed in the middle of the water supply pipe 3, which drives the water inside the heating water tank 2 to flow. The water pump 5 is located outside the outer pipe 1, and a heating coil 13 is set outside the inner pipe 21. The heating coil 13 heats the inner pipe 21, thereby heating the oil inside the inner pipe 21. The heating coil 13 is located between the outer pipe 1 and the inner pipe 21. The heating efficiency is improved by using both electromagnetic heating and hot water heating. Different heating methods can be changed under different needs to protect the pipes and heating devices.

[0036] Reference Figures 2-4 The mounting ring 6 has multiple round holes 7 in the middle, which are arranged in a ring around the mounting ring 6. The mounting ring 6 is located at both ends of the outer tube 1. The heating device is installed on the water pipe through the mounting rings 6 at both ends. A rotating rod 22 is fixedly connected to one side of the rotating shaft 16. The rotating rod 22 can rotate on the rotating shaft 16. Multiple blades 20 are fixedly connected to the outside of the rotating rod 22. The blades 20 drive the rotating rod 22 to rotate through the liquid flow, forming a rotation without energy consumption. This drives the scraper 19 to rotate and clean the inner wall. A filter plate 10 is installed inside the inner tube 21. The filter plate 10 is used to filter impurities in the oil entering from the inlet 8. The filter plate 10 has multiple filter holes 11 starting from the middle, which allow the oil to pass through and filter impurities.

[0037] Working principle: First, when transporting oil, the flow of oil drives the blade 20 to rotate the rotating rod 22. The rotation of the rotating rod 22 drives the rotating shaft 16 to rotate, which in turn drives the scraper 19 to rotate. The scraper 19 is in contact with the inner wall of the inner tube 21. When the scraper 19 rotates, it scrapes the inner tube 21 circumferentially. The truss structure composed of the fixed rod 17 and the connecting rod 18 ensures that the scraper 19 is always in contact with the tube wall. The filter plate 10 is located at the inlet 8 to clean impurities in the oil.

[0038] Secondly, the heating water tank 2 uses the water pump 5 to deliver high-temperature water through the water pipe 3 into the heating water pipe 12 spirally wound on the outside of the inner pipe 21. The high-temperature water flows through the other end of the heating water pipe 12 to the return water pipe 4, and then flows back into the heating water tank 2 through the return water pipe 4, forming a closed-loop heat conduction. After the heating coil 13 is energized, it directly performs electromagnetic induction heating on the inner pipe 21, forming a dual heat source structure with the water circulation system, which makes the heating effect better.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
