Description

Technical Field

[0001] The utility model relates to the technical field of cracking oil transportation, in particular to an oil transportation device. Background Art

[0002] With the rapid development of the automobile industry, a large number of waste tires are discarded or piled up in the open air, causing serious pollution to the environment. It not only affects human health, but is also a huge waste of resources. Therefore, the recycling and secondary utilization of waste automobile tires is particularly important. In recent years, people put waste tires into cracking furnaces for high-temperature cracking, recover useful substances from the cracking products for reuse, and develop and utilize carbon black waste tires to produce gasoline, diesel and pyrolytic carbon black, which provides a good direction for the utilization of waste tires.

[0003] The pyrolysis oil extracted from the waste tire is in a gaseous state before being condensed into a liquid state. The gaseous pyrolysis oil (i.e., oil and gas) flows from the cracking furnace along the delivery pipeline into a condenser for condensation. During the transportation of the oil and gas along the delivery pipeline, since the oil and gas and the inner wall of the pipeline produce relative motion, part of the oil and gas will adhere to the inner wall of the pipeline under the effect of factors such as friction during this process. The long-term transportation of the oil and gas will cause a thick layer of oil to adhere to the inner wall of the pipeline. The accumulation of the oil layer will not only cause the loss of the pyrolysis oil, but also reduce the flow rate of the pipeline, so that the oil and gas are obstructed during transportation. Therefore, an oil transportation device is proposed to solve the above-mentioned problem. Utility Model Content

[0004] Based on the above description, the utility model provides an oil delivery device to solve the problem that part of the cracked oil adheres to the inner wall of the existing oil pipeline when transporting oil and gas.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the delivery pipeline includes a main pipe, and the inner wall of the main pipe is provided with a mounting groove.

[0008] Furthermore, a flange is arranged on the outside of the main pipe, and holes are arranged on the surface of the flange, and the holes are distributed in an annular shape with equal distances.

[0009] Furthermore, an annular plate is provided on the outer surface of the tube body, and a connecting hole is provided on the surface of the annular plate. The screw penetrates through the connecting hole and the hole to connect the delivery pipeline and the connecting piece.

[0010] Furthermore, the outer surface of the connecting pipe is provided with threads, and the connecting pipe passes through the annular plate and is communicated with the annular groove.

[0011] Furthermore, the connecting pipes are distributed in an annular shape with equal distances, and are staggered with the connecting holes.

[0012] Furthermore, an annular groove is provided at one end of the tube body, and a communicating hole is provided at the other end of the tube body, and the communicating hole is communicated with the annular groove.

[0013] Furthermore, a clamping groove is provided inside the annular groove, and a diameter of the clamping groove is larger than a diameter of the annular groove.

[0014] Furthermore, a sealing groove is provided on the outer surface of the tube body, a sealing ring is provided inside the sealing groove, and the sealing ring is in contact with the inner wall of the conveying pipe.

[0015] Furthermore, the guide inner tube includes a first inner tube, a second inner tube is provided at one end of the first inner tube, the second inner tube is arranged inside the groove and is in contact with the conveying pipe and the connecting piece at the same time, and a support is provided on the inner wall of the first inner tube, and the support is in contact with the inner wall of the annular groove.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] 1. The utility model provides a delivery pipe and a connecting piece and other components, and cooperates with the connecting pipe and the annular groove, so that the air outside the delivery pipe can enter the inside of the annular groove through the connecting pipe, and the air entering forms an airflow and flows along the direction of the inner wall of the delivery pipe, thereby forming an annular airflow on the inner wall of the delivery pipe;

[0018] 2. By setting the guide inner tube, the air restriction effect is achieved, so that the air entering the annular groove from the connecting tube can only move along the second inner tube toward the first inner tube. The direction of air flow is the direction of oil and gas transportation, so as to ensure that an annular air curtain is formed between the oil and gas and the inner wall of the transportation pipeline during the transportation of oil and gas. Under the action of the annular air curtain, the oil and gas are isolated to prevent the oil and gas from directly contacting the inner wall of the transportation pipeline.

It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0032] See also Figure 1-Figure 5 , an oil delivery device, comprising:

[0033] A delivery pipeline 1, the delivery pipeline 1 comprises a main pipe 11, the inner wall of the main pipe 11 is provided with a mounting groove 13, the outer side of the main pipe 11 is provided with a flange 12, the surface of the flange 12 is provided with holes, and the holes are distributed in an annular shape with equal spacing;

[0034] Based on the above, the delivery pipeline 1 plays the role of transporting oil and gas. What is drawn in the figure is only a part of the delivery pipeline 1. Compared with the traditional pipeline, the delivery pipeline 1 only has an additional installation groove 13. The installation groove 13 plays the role of limiting the connecting piece 2 and fixing the guiding inner tube 3. The flange 12 is connected to the connecting piece 2 by screws and nuts.

[0035] like Figure 2-Figure 4 , Figure 6 and Figure 7 As shown, the connector 2 is disposed between the delivery pipes 1 and connected to the delivery pipes 1 by screws and nuts, and includes a pipe body 21, an annular plate 22, a connecting pipe 23, an annular groove 25 and a connecting hole 27, wherein:

[0036] The outer surface of the tube body 21 is provided with an annular plate 22, and the surface of the annular plate 22 is provided with a connecting hole 24. The screw passes through the connecting hole 24 and the hole to connect the delivery pipe 1 and the connecting piece 2. One end of the tube body 21 is provided with an annular groove 25, and the other end of the tube body 21 is provided with a connecting hole 27. The connecting hole 27 is connected with the annular groove 25. The outer surface of the tube body 21 is provided with a sealing groove 26, and a sealing ring 4 is provided inside the sealing groove 26. The sealing ring 4 contacts the inner wall of the delivery pipe 1.

[0037] A connecting pipe 23 is provided on the outer surface of the annular plate 22 and is in communication with the annular groove 25. The outer surface of the connecting pipe 23 is provided with a thread. The connecting pipe 23 penetrates the annular plate 22 and is in communication with the annular groove 25. The connecting pipe 23 is distributed in an annular shape with equal distances and is staggered with the connecting holes 24. A clamping groove 28 is provided inside the annular groove 25. The diameter of the clamping groove 28 is larger than the diameter of the annular groove 25.

[0038] Based on the above, the connecting piece 2 is connected to the conveying pipe 1 through screws and nuts. In this process, the tube body 21 extends to the inside of the mounting groove 13. The airflow can enter from the annular groove 25 and be discharged from the connecting hole 27. The setting of the connecting pipe 23 allows external air to pass into the annular groove 25 to provide airflow.

[0039] like Figure 2-Figure 4 and Figure 8 As shown, the guide inner tube 3 is arranged inside the connecting member 2 and includes a first inner tube 31 and a second inner tube 32. The guide inner tube 3 includes the first inner tube 31. One end of the first inner tube 31 is provided with the second inner tube 32. The second inner tube 32 is arranged inside the clamping groove 28 and contacts with the conveying pipeline 1 and the connecting member 2 at the same time. The inner wall of the first inner tube 31 is provided with a support member 33. The support member 33 contacts with the inner wall of the annular groove 25.

[0040] Based on the above, the guide inner tube 3 plays a role in limiting the airflow. When the guide inner tube 3 is set inside the groove 28, it is subject to the lateral pressure and restriction of the conveying pipeline 1, so that the guide inner tube 3 is fixed inside the groove 28. When the airflow at the connecting pipe 23 enters the annular groove 25, it is hindered by the guide inner tube 3, so that the airflow can only move along the second inner tube 32 toward the direction of the first inner tube 31, thereby playing a role in guiding the flow.

[0041] In actual use, the present embodiment is provided with the connecting piece 2 and the guide inner tube 3 between the conveying pipeline 1, and the airflow is introduced from the connecting tube 23, so that the airflow moves along the second inner tube 32 toward the first inner tube 31. In this process, the airflow forms an annular air curtain along the inner wall of the conveying pipeline 1. The air of the air curtain comes from the external air, so there is very little oil and gas in the air curtain, which can isolate the oil and gas from the conveying pipeline 1 during the oil and gas transportation.

[0042] According to the actual situation, multiple sections of the conveying pipeline 1 can be installed in the same conveying path, so that a number of connectors 2 and guide inner tubes 3 are installed at equal distances. When the airflow is input, the airflows between the connectors 2 can be interconnected, thereby extending the length of the entire air curtain, so as to achieve the laying of the air curtain to the entire oil and gas transportation path;

[0043] The oil delivery device is provided with a delivery pipeline 1, a connector 2, a guide inner tube 3 and a sealing ring 4, so that when the delivery pipeline 1 is delivering oil and gas, air can be introduced into the delivery pipeline 1 to generate an annular air curtain on the inner wall of the delivery pipeline 1. Under the action of the annular air curtain, the oil and gas are isolated from the delivery pipeline 1, so that the oil particles in the oil and gas will not adhere to the inner wall of the delivery pipeline 1, wherein the sealing ring 4 plays a sealing role;

[0044] Compared with traditional oil pipelines, the oil pipeline device is less likely to cause cracking oil to adhere to the inner wall of the pipeline.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
