Description

Technical Field

[0001] This utility model relates to the field of oil pipeline technology, and in particular to an oil transfer pipe with anti-icing function. Background Technology

[0002] After oil is extracted, it must be transported to appropriate processing facilities for optimal utilization, and oil pipelines are an essential piece of equipment for this purpose. However, during oil extraction, high wax content and high oil concentration often cause difficulties in transporting oil through pipelines. Especially in cold seasons, the wax in the oil solidifies at low temperatures, significantly increasing flow resistance and necessitating the addition of insulation layers to the pipelines to maintain the internal temperature.

[0003] For example, the public announcement (CN214093365U) discloses an insulated and corrosion-resistant oil pipeline, including a steel pipe, an anti-corrosion coating, an intermediate layer, and a protective layer. The steel pipe, the anti-corrosion coating, the intermediate layer, and the protective layer are coaxially sleeved together. The anti-corrosion coating is applied to the outer peripheral wall of the steel pipe. The intermediate layer includes an insulation layer, a reinforcing layer, and an insulation filler. The insulation layer is an aerogel felt connected to the outer peripheral wall of the anti-corrosion coating. The reinforcing layer is a steel mesh grid connected to the outer peripheral wall of the insulation layer. The insulation filler is a rock wool layer filled within the steel mesh grid. The protective layer is connected to the outer peripheral wall of the intermediate layer.

[0004] In existing technologies, although oil pipelines are equipped with insulation fillers for insulation, they still experience icing and blockage when used in cold regions of northern my country. The icing cannot be effectively melted, and the presence of sand and gravel in the oil can also easily clog the pipeline, affecting the normal transportation of oil. Therefore, an oil transfer pipe with anti-icing function is provided. Utility Model Content

[0005] The purpose of this application is to provide an oil transfer pipe with anti-icing function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: an oil transfer pipe with anti-icing function, comprising a pipe body, a silicon carbide layer on the outer side of the pipe body, a heating wire inside the silicon carbide layer, a temperature sensor inside the pipe body, a collection trough at the bottom inside the pipe body, a first blocking member on one side of the collection trough, a second blocking member on the other side of the collection trough, a filter screen above the collection trough, a connector on the top of the filter screen, the connector being connected to the filter screen's rotating shaft, a discharge valve at the bottom of the collection trough, a discharge port at the bottom of the discharge valve, a battery at the bottom of the temperature sensor, and a controller on one side of the discharge valve.

[0007] Preferably, the silicon carbide layer is sleeved with the tube body, the heating wire is sleeved with the silicon carbide layer, and the temperature sensor is bolted to the tube body.

[0008] Preferably, the connector is heat-fused to the pipe body, and the filter screen is movably connected to the pipe body.

[0009] Preferably, the first blocking member is thermally fused to the pipe body, and the second blocking member is thermally fused to the pipe body.

[0010] Preferably, the discharge valve is bolted to the pipe body, the discharge valve is connected to the material collection trough pipe, and the discharge port is connected to the discharge valve pipe.

[0011] Preferably, the battery is bolted to the tube body, the controller is bolted to the tube body, and the controller is connected to the heating wire, temperature sensor, and discharge valve wires respectively.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, a pipe body, a first blocking component, a second blocking component, a filter screen, a connecting component, a discharge port, a discharge valve, and a controller are provided. The filter screen rotates along the connecting component following the direction of oil flow. The first and second blocking components limit and support the filter screen. The filter screen filters large particles of sand and gravel in the oil. The filtered sand and gravel remain in the collection tank. The controller can control the discharge valve to open. The discharge valve opens the discharge port, allowing the filtered sand and gravel to be discharged through the discharge port. This facilitates filtration according to different oil flow directions and helps to assist in sand filtering and discharge.

[0014] 2. In this utility model, a silicon carbide layer, a heating wire, and a temperature sensor are provided. When used in cold weather, the temperature sensor monitors the internal temperature of the tube in real time. When the temperature is detected to be lower than the preset value, the controller controls the heating wire to work. The heating wire heats the silicon carbide layer, thereby providing auxiliary heat treatment for the tube and preventing ice formation inside the tube, which could lead to blockage. This provides auxiliary heat treatment and prevents ice formation. Attached Figure Description

[0025] Example: Reference Figure 1-4 The oil transfer pipe shown includes a pipe body 1, a silicon carbide layer 2 on the outside of the pipe body 1, a heating wire 3 inside the silicon carbide layer 2, a temperature sensor 11 inside the pipe body 1, a collection trough 4 at the bottom inside the pipe body 1, a first blocking member 5 on one side of the collection trough 4, a second blocking member 6 on the other side of the collection trough 4, a filter screen 7 above the collection trough 4, a connector 8 at the top of the filter screen 7, the connector 8 being connected to the rotating shaft of the filter screen 7, a discharge valve 10 at the bottom of the collection trough 4, a discharge port 9 at the bottom of the discharge valve 10, a battery 12 at the bottom of the temperature sensor 11, and a controller 13 on one side of the discharge valve 10. This utility model effectively prevents icing and blockage inside the transfer pipe by installing a heating wire 3 on the outside to provide low-temperature auxiliary heating to the pipe body 1, making it suitable for use in oil pipeline connections.

[0026] With the above structure: the silicon carbide layer 2 is sleeved with the tube body 1, the heating wire 3 is sleeved with the silicon carbide layer 2, and the temperature sensor 11 is bolted to the tube body 1 for auxiliary heating, heat preservation and antifreeze work.

[0027] With the above structure: the connector 8 is heat-fused to the pipe body 1, the filter screen 7 is movably connected to the pipe body 1, the filter screen 7 is made of metal mesh and is used to filter sand and gravel in the oil, the first blocking member 5 is heat-fused to the pipe body 1, the second blocking member 6 is heat-fused to the pipe body 1, and can work together to block the filter screen 7 according to different oil conveying directions, the discharge valve 10 is bolted to the pipe body 1, the discharge valve 10 is pipe-connected to the collection trough 4, and the discharge port 9 is pipe-connected to the discharge valve 10 for automatic discharge of sand and gravel.

[0028] With the above structure: the battery 12 is bolted to the tube body 1, the controller 13 is bolted to the tube body 1, the controller 13 is wired to the heating wire 3, the temperature sensor 11 and the discharge valve 10 respectively, and the controller 13 adopts a multi-interface programmable controller to control the operation of each component.

[0029] The working principle of this embodiment is as follows: Connect both ends of the adapter pipe to the oil pipeline. After the oil enters the pipe body 1, the filter screen 7 rotates along the connector 8 following the oil flow direction, causing the filter screen 7 to fit against the first blocking member 5 or the second blocking member 6. The first blocking member 5 and the second blocking member 6 limit and support the filter screen 7. Large particles of sand and gravel in the oil are filtered through the filter screen 7. The filtered sand and gravel remain in the collection trough 4. The controller 13 can control the discharge valve 10 to open, opening the discharge port 9, allowing the filtered sand and gravel to be discharged through the discharge port 9. This facilitates filtration according to different oil flow directions, achieving the effect of auxiliary sand filtering and discharge. In cold weather, the temperature sensor 11 monitors the internal temperature of the pipe body 1 in real time. When the detected temperature is lower than the preset value, the controller 13 controls the heating wire 3 to operate. The heating wire 3 heats the silicon carbide layer 2, thereby providing auxiliary heat treatment to the pipe body 1, preventing ice formation and blockage, achieving the effect of auxiliary heating and anti-icing.
