Description

Technical Field

[0001] The utility model relates to the technical field of oil field transportation equipment, in particular to a vehicle-mounted vacuum oil pulling device. Background Art

[0002] In the crude oil transportation operation in the oil field, the oil pulling tank is the key equipment. The traditional open oil pulling tank has many defects. When loading and unloading crude oil, a large amount of natural gas will evaporate into the air, which contains a large amount of light components of petroleum, resulting in a significant decrease in oil production. For example, statistics from some oil fields show that the loss of light components during the loading and unloading process of open oil pulling tanks can reach 15%-30%. The volatilized natural gas also contains harmful substances such as sulfides, which seriously pollute the environment and form a flammable mixture in the air, posing a huge safety hazard and easily causing fire or explosion accidents. This is common in past oil field accident cases. With the continuous tightening of environmental protection regulations, open oil pulling tanks have been difficult to meet environmental protection requirements.

[0003] To improve this situation, closed oil pulling tanks are adopted, but closed oil pulling tanks face new challenges in actual applications. When filling oil, the gas in the tank cannot be discharged in time, resulting in pressure buildup and gas blockage, which significantly prolongs the filling time and makes the originally efficient filling process slow. At the same time, pressure buildup causes the space in the tank to be unable to be fully utilized, and the oil is not fully filled. Its maximum loading capacity can often only reach 50% of the tank volume, which means that more pulls are required to transport the same amount of crude oil, and the transportation cost increases significantly, including vehicle use costs, labor costs, and fuel costs. Based on the above situation, it is of great practical significance and necessity to develop a vehicle-mounted vacuum oil pulling device to solve the problems of pressure buildup and gas blockage and insufficient oil filling in closed oil pulling tanks. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a vehicle-mounted vacuum oil pulling device to solve the problems of pressure buildup and gas blockage in the oil pulling tank, insufficient oil filling, and oil and gas leakage during loading and unloading of crude oil.

[0005] For the above purposes, the present utility model provides an on-vehicle vacuum oil drawing device, including: a tanker truck, on one side of which a vacuum air pump is installed. The air inlet of the vacuum air pump is connected to a first air duct, and the other end of the first air duct is installed at one end of an adjustment assembly, which is used to adjust the opening and closing of the pipe orifice. The air outlet of the vacuum air pump is connected to a second air duct, and the other end of the second air duct is installed on a gas storage tank, which is installed on the tanker truck. At one end of the gas storage tank far from the vacuum air pump, an air delivery pipe is installed. The end of the air delivery pipe far from the gas storage tank is installed on one side of the adjustment assembly. At one end of the adjustment assembly far from the air delivery pipe, an air delivery pipe is installed, and the other end of the air delivery pipe is installed on one side of an oil tank, which is installed on one side of the tanker truck. On one side of the oil tank far from the gas storage tank, an oil discharge port is installed. On one side of the oil tank far from the gas storage tank, a manhole is installed. On the same side of the oil tank as the manhole, an oil filling port is installed.

[0007] Preferably, the adjustment assembly includes a housing installed between the air delivery pipe and the air delivery pipe. A transfer ball is movably installed in the housing, and a handle is installed at one end of the transfer ball.

[0008] Preferably, a first channel is transversely opened in the housing, and a second channel is longitudinally opened in the housing. The first channel and the second channel penetrate each other. An installation cavity is opened inside the housing, which is adapted to the transfer ball. An air vent hole is opened on the transfer ball in a direction perpendicular to the first channel.

[0009] Preferably, a connection port is opened on one side of the transfer ball close to the handle, a second through hole is opened on the side of the transfer ball far from the connection port, and a first through hole is opened on the transfer ball along the radial direction of the first channel.

[0012] Advantages of the utility model:

[0013] 1. In this on-vehicle vacuum oil drawing device, by installing a vacuum air pump such as an air storage tank and a vacuum air pump, all the gas in the oil drawing tank is pumped out during oil loading, creating a negative pressure in the oil tank. Then, relying on the vacuum suction, the oil tank is filled. During oil unloading, the crude oil in the tank is squeezed out by the pressure of the compressed gas extracted, realizing a fully enclosed process for loading and unloading crude oil, eliminating the risk of oil and gas leakage, increasing both the output and shortening the time for loading and unloading crude oil, improving the carrying capacity, and solving the environmental protection problem.

[0014] 2. In this on-vehicle vacuum oil drawing device, by providing an adjusting component, when it is necessary to connect the gas transmission pipe with the first gas transmission channel, only need to rotate the handle to a position parallel to the first channel. At this time, the first through hole will communicate with the first channel, and the gas can flow into the gas transmission pipe through this channel. When it is necessary to connect the gas transmission pipe with the gas supply pipe, only need to rotate the handle by a certain angle so that the ventilation hole communicates with the first channel. At this time, the gas can flow into the gas supply pipe through the ventilation hole. Such an operation method is simple and intuitive, and can ensure that the gas flow path in the device is accurate, thus realizing precise control of the crude oil loading and unloading process.

[0025] As Figures 1 to 5As shown in the figure, the on-vehicle vacuum oil drawing device includes: a tanker truck 1, a vacuum pump 10 is installed on one side of the tanker truck 1, an intake port of the vacuum pump 10 is connected to a first air duct 11, the other end of the first air duct 11 is installed at one end of an adjustment assembly, and the adjustment assembly is used to adjust the opening and closing of the pipe orifice. An outlet port of the vacuum pump 10 is connected to a second air duct 12, the other end of the second air duct 12 is installed on a gas storage tank 2, the gas storage tank 2 is installed on the tanker truck 1, an air supply pipe 9 is installed at one end of the gas storage tank 2 away from the vacuum pump 10, one end of the air supply pipe 9 away from the gas storage tank 2 is installed on one side of the adjustment assembly, and one end of the adjustment assembly away from the air supply pipe 9 is installed with an oil delivery pipe 8, the other end of the oil delivery pipe 8 is installed on one side of an oil tank 3, the oil tank 3 is installed on one side of the tanker truck 1, an oil discharge port 7 is installed on one side of the oil tank 3 away from the gas storage tank 2, a manhole 4 is installed on one side of the oil tank 3 away from the gas storage tank 2, and an oil filling port 5 is installed on the same side of the oil tank 3 as the manhole 4; a valve 6 is installed on one side of the second air duct 12 close to the gas storage tank 2, a valve 6 is also installed on one side of the air supply pipe 9 close to the gas storage tank 2, a valve 6 is installed on the oil discharge port 7, and a valve 6 is installed on the oil filling port 5;

[0026] First, close the valve 6 on the air supply pipe 9, open the valve 6 on the second air duct 12, then operate the adjustment assembly to connect the oil delivery pipe 8 with the first air duct 11, start the vacuum pump 10 to pump the air in the oil tank 3 into the gas storage tank 2 through the vacuum pump 10. After the extraction is completed, operate the adjustment assembly to disconnect the oil delivery pipe 8 from the first air duct 11, then close the valve 6 on the second air duct 12, and then open the valve 6 on the oil filling port 5. Connect the external oil delivery pipe to one end of the oil filling port 5. Since the vacuum pump 10 creates a negative pressure after pumping out all the air in the oil tank 3, the crude oil in the oil storage tank automatically flows into the oil tank 3 at this time. When the oil tank 3 is full, close the valve 6 on the oil filling port 5 to complete the loading of the crude oil. When the tanker truck 1 arrives at the destination and wants to take out the crude oil in the oil tank 3, only need to open the valve 6 on the oil discharge port 7, then operate the adjustment assembly to connect the oil delivery pipe 8 with the air supply pipe 9, and then open the valve 6 on the air supply pipe 9.

[0028] The adjusting assembly is easy to operate. When it is necessary to connect the gas transmission pipe 8 with the first gas transmission channel 11, only the handle 13 needs to be rotated to a position parallel to the first channel 15. At this time, the first through hole 19 will communicate with the first channel 15, and the gas can flow into the gas transmission pipe 8 through this channel. When it is necessary to connect the gas transmission pipe 8 with the gas supply pipe 9, only the handle 13 needs to be rotated by a certain angle so that the ventilation hole 29 communicates with the first channel 15. At this time, the gas can flow into the gas supply pipe 9 through the ventilation hole 29. Such an operation method is simple and intuitive, and can ensure that the gas flow path in the device is accurate, thus realizing the precise control of the crude oil loading and unloading process.
