Technical Field
[0001] The utility model belongs to the technical field of pipelines, and particularly relates to a naphtha loading and unloading pipeline. Background Art
[0002] Naphtha is one of the petroleum products, also known as chemical light oil and crude gasoline. It is a light oil used as a chemical raw material produced from crude oil or other raw materials. It is mainly used as a chemical raw material and has various distillation ranges due to different uses. The distillation range is about 220°C at the final boiling point. When used as a cracking raw material for producing ethylene, the fraction of 70°C - 145°C is used, which is called light naphtha. When the purpose is to produce aromatics or high-octane gasoline, the fraction of 70°C - 180°C is used, which is called heavy naphtha. When used as a solvent, it is called solvent naphtha. The aromatic solvent from coal tar is also called heavy naphtha or solvent naphtha. The naphtha unloading pipeline at the 10,000-ton berth of the terminal and the light naphtha pipeline loading pipeline share an oil transfer arm, and the shared DN450 pipeline is about 300 meters long. Naphtha is a colorless, transparent or slightly yellowish liquid at normal temperature and pressure, with a special smell, insoluble in water, having a density of 650 - 750 kg / m3, and a sulfur content of not more than 0.08%. Naphtha is a light oil product obtained by distilling crude oil or cutting corresponding fractions through secondary processing of petroleum. It is stored in a cool and ventilated warehouse, away from fire sources and heat sources. The warehouse temperature should not exceed 30°C. Keep the container sealed. It should be stored separately from oxidants. Use explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to generating sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
[0003] For some existing naphtha loading and unloading pipelines, after each naphtha unloading, in order to ensure that the quality of the light naphtha loaded onto the ship is not contaminated, there is a lack of a device for cleaning the naphtha pipeline in the shared pipeline. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a naphtha loading and unloading pipeline to solve the problem that for some existing naphtha loading and unloading pipelines, after each naphtha unloading, in order to ensure that the quality of the light naphtha loaded onto the ship is not contaminated, there is a lack of a device for cleaning the naphtha pipeline in the shared pipeline as mentioned in the above background art.
[0005] To achieve the above object, the present utility model provides the following technical solutions: A naphtha loading and unloading pipeline, including a pipeline body, an installation seat is fixedly connected to the outside of the pipeline body, a blower is fixedly connected to one side of the top of the installation seat, a motor is fixedly connected to the other side of the top of the installation seat, a control switch is fixedly connected to one side of the top of the installation seat close to the motor, a folding groove is arranged inside the installation seat, an air delivery channel is fixedly connected to the bottom of the blower, fixing blocks are fixedly connected to both sides of the air delivery channel, a second support seat is fixedly connected to one side of the fixing block, a folding pipe is fixedly connected to the bottom of the air delivery channel, an air outlet pipe is fixedly connected to one end of the folding pipe, and an air outlet is arranged inside the air outlet pipe.
[0006] Preferably, a first support seat is snap-connected to the bottom of the installation seat.
[0007] Preferably, a support base is fixedly connected to the bottom of the first support seat.
[0008] Preferably, protective seats are fixedly connected to both sides of the support base, and there are two protective seats.
[0009] Preferably, the air delivery channel penetrates through one side inside the pipeline body and the installation seat.
[0010] Preferably, the folding pipe is made of a corrosion-resistant material.
[0011] Preferably, the outer surface of the first support seat is arc-shaped.
[0012] Preferably, two fixing blocks and two second support seats are symmetrically arranged.
[0013] Compared with the prior art, the present utility model provides a naphtha loading and unloading pipeline, which has the following beneficial effects:
[0014] 1. By setting a blower in the present utility model, after each unloading of naphtha, in order to ensure that the quality of light naphtha loaded onto the ship is not contaminated, the naphtha pipeline in its shared pipeline can be blown and cleaned. When using the blower, the control switch controls the blower to start working. When the blower is working, the air blown out from the air delivery channel makes the folded folding pipe start to expand and contract under the action of the wind force, and drives the air outlet pipe, so that the air outlet pipe is placed in the middle position inside the pipeline body. The air flow in the air delivery channel can be blown out from the air outlet into the pipeline on one side through the air outlet pipe. Through the wind force, the residual petroleum in the pipeline is blown out to achieve the cleaning effect.
[0015] 2. The utility model provides a first support base, which can support and protect the pipeline body and the mounting base. Since most naphtha loading and unloading operations are carried out outdoors with uneven terrain, if the naphtha loading and unloading pipelines are directly laid on the ground, the uneven angle will easily affect the mining progress, and directly laying on the ground is likely to cause wear to the pipeline body, affecting the service life of the overall structure. Adding the first support base and the support base can, to a certain extent, extend the service life of the structure.
[0016] Parts not involved in this device are the same as or can be implemented using existing technologies. The structure of this utility model is scientific and reasonable, safe and convenient to use, and provides great help to people. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a naphtha loading and unloading pipeline, including a pipeline body 1, an installation seat 2 is fixedly connected to the outside of the pipeline body 1, a blower 3 is fixedly connected to one side of the top of the installation seat 2, a motor 4 is fixedly connected to the other side of the top of the installation seat 2, a control switch 5 is fixedly connected to one side of the top of the installation seat 2 close to the motor 4, a folding groove 9 is arranged inside the installation seat 2, an air delivery channel 10 is fixedly connected to the bottom of the blower 3, fixing blocks 11 are fixedly connected to both sides of the air delivery channel 10, a second support seat 12 is fixedly connected to one side of the fixing block 11, a folding pipe 13 is fixedly connected to the bottom of the air delivery channel 10, an air outlet pipe 14 is fixedly connected to one end of the folding pipe 13, an air outlet 15 is arranged inside the air outlet pipe 14. After unloading naphtha each time, in order to ensure that the quality of light naphtha during loading onto the ship is not contaminated, the naphtha pipeline in its common pipeline can be cleaned by blowing air. By setting the blower 3, during use, the control switch 5 controls the blower 3 to start working. When the blower 3 is working, the air blown out from the air delivery channel 10 causes the folded folding pipe 13 to start telescoping, and it drives the air outlet pipe 14, making the air outlet pipe 14 located at the middle position inside the pipeline body 1. The air flow in the air delivery channel 10 can be blown out from the air outlet 15 into the pipeline on one side through the air outlet pipe 14. Through the wind force, the residual petroleum in the pipeline is blown out to achieve the cleaning effect.
[0025] In the present utility model, preferably, a first support seat 6 is snap-fitted to the bottom of the installation seat 2. The first support seat 6 can play a role in supporting and protecting the pipeline body 1 and the installation seat 2. Since most naphtha loading and unloading is in an outdoor environment with uneven terrain, if the naphtha loading and unloading pipeline is directly laid on the ground with an uneven angle, it is easy to affect the mining progress, and directly laying it on the ground is likely to cause wear to the pipeline body 1, affecting the service life of the overall structure.
[0026] In the present utility model, preferably, a support base 7 is fixedly connected to the bottom of the first support seat 6. Adding the first support seat 6 and the support base 7 can, to a certain extent, extend the service life of the structure.
[0027] In the present utility model, preferably, protective seats 8 are fixedly connected to both sides of the support base 7. There are two protective seats 8, which increases the grounding area of the structure and improves the stability of the overall structure.
[0028] In the present utility model, preferably, the air delivery channel 10 runs through one side inside the pipeline body 1 and the installation seat 2.
[0029] In the present utility model, preferably, the folding pipe 13 is made of corrosion-resistant material.
[0030] In the present utility model, preferably, the outer surface of the first support seat 6 is arc-shaped.
[0031] In the present utility model, preferably, there are two fixing blocks 11 and two second support seats 12 symmetrically arranged.
[0032] The working principle and usage process of the present utility model: When in use, by setting the blower 3 and controlling the switch 5 to operate the blower 3, when the blower 3 is working, the air will be blown out from the air delivery channel 10. Under the action of the wind force, the folded folding tube 13 starts to expand and contract, and drives the air outlet pipe 14, so that the air outlet pipe 14 is located at the middle position inside the pipeline body 1. The air flow in the air delivery channel 10 can be blown out from the air outlet 15 into the pipeline on one side through the air outlet pipe 14. By the wind force, the residual oil in the pipeline can be blown out to achieve the cleaning effect. By setting the first support seat 6, the first support seat 6 can play a role in supporting and protecting the pipeline body 1 and the mounting seat 2.
[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
