Description

Technical Field

[0001] The utility model relates to the technical field of ship fuel monitoring systems, and specifically to an oil return measurement device for a ship fuel monitoring system. Background Art

[0002] Ship fuel is various fuels used for ship internal combustion engines and other ship equipment, which are mainly divided into two categories: distillate fuel oil and residual fuel oil. A ship fuel monitoring system is a comprehensive system designed to monitor the usage, quality, and safety performance of ship fuel in real time to ensure the normal operation of the ship and the effective management of fuel. The oil return measurement in a ship fuel monitoring system is an important link in fuel management, which involves accurate measurement and analysis of the returned fuel in the fuel system to ensure the effective utilization of fuel and the normal operation of the system.

[0003] In a ship fuel system, a certain amount of oil return will be generated after the fuel is burned. This oil return may come from parts such as the combustion chamber of the main engine, turbocharger, and fuel filter. The oil return usually contains unburned fuel, water, impurities, and lubricating oil. The oil return process is to collect the oil return through specific pipelines and equipment and transport it to a designated treatment device or oil storage equipment.

[0004] In a ship fuel monitoring system, an oil return measurement device is required. Nowadays, during the process of oil return measurement, the staff usually measures directly through the amount of oil return inside the oil return barrel. However, manual measurement has a large error and cannot accurately measure the amount of oil return. As a result, it may affect the staff's judgment of the ship fuel system and cannot meet the production requirements. Therefore, an oil return measurement device for a ship fuel monitoring system is proposed to solve the problems raised above. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an oil return measurement device for a ship fuel monitoring system, which has the advantage of relatively accurate oil return measurement, and solves the problem that usually the amount of oil return inside the oil return barrel is directly measured, but manual measurement has a large error and cannot accurately measure the amount of oil return, which may affect the staff's judgment of the ship fuel system and cannot meet the production requirements.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An oil return measurement device for a ship fuel monitoring system includes a base and a gas-liquid separation tank arranged on the top of the base. A support frame is fixedly connected between the base and the gas-liquid separation tank. An air-liquid separation component capable of removing bubbles in the oil return is arranged inside the gas-liquid separation tank;

[0007] The gas-liquid separation component includes a sealing cover plate arranged at the top of the gas-liquid separation tank. A fixing rod is fixedly connected inside the sealing cover plate. A filter plate is slidably connected inside the gas-liquid separation tank. Two support rods are fixedly connected between the sealing cover plate and the filter plate. An exhaust pipe extending into its interior is fixedly connected to the top of the sealing cover plate.

[0008] Furthermore, fixing blocks are fixedly connected to the outer parts of both the sealing cover plate and the gas-liquid separation tank. A fixing bolt is threadedly connected to the fixing block on the sealing cover plate and extends to the fixing block on the gas-liquid separation tank.

[0009] Furthermore, an oil inlet pipe communicating with the inside is fixedly connected to one side of the gas-liquid separation tank. Valves are fixedly installed on the outer parts of both the oil inlet pipe and the exhaust pipe.

[0010] Furthermore, an oil return pipe is fixedly connected to the bottom of the gas-liquid separation tank. One end of the oil return pipe away from the gas-liquid separation tank is fixedly connected to an oil pump.

[0011] Furthermore, the oil pump is fixedly connected to the top of a base. A fuel flowmeter is arranged on the top of the base. Both ends of the fuel flowmeter are fixedly connected with conveying pipes. One end of the fuel flowmeter close to the oil pump is fixedly connected through a conveying pipe.

[0012] Furthermore, an oil return barrel is fixedly connected to one side of the top of the base away from the gas-liquid separation tank. A fuel filter communicating with the inside is fixedly installed on the top of the oil return barrel. The fuel filter is fixedly connected to the fuel flowmeter through a fuel filter.

[0013] Furthermore, a flow guide plate is fixedly connected to the inner bottom wall of the oil return barrel. A liquid level window is fixedly connected to the front of the oil return barrel. An installation vertical plate is fixedly installed on the front of the top of the base.

[0014] Compared with the prior art, the present utility model provides an oil return measurement device for a ship fuel monitoring system, which has the following beneficial effects:

[0015] 1. For this oil return measurement device of the ship fuel monitoring system, by arranging a gas-liquid separation tank and an oil inlet pipe, when ship fuel enters the inside of the gas-liquid separation tank through the oil inlet pipe, due to the action of gravity, the air in the ship fuel moves upward, and the ship fuel and other impurities drop downward. Then, by arranging an exhaust pipe, the effect of gas-liquid separation of the ship fuel can be achieved, avoiding bubbles from affecting the measurement data of the fuel flowmeter. By arranging a filter plate, the impurities in the ship fuel can be filtered, improving the practicability of the device.

[0016] 2. The return oil measurement device of the ship fuel monitoring system can make the ship fuel enter the inside of the return oil barrel through the fuel pump and the return oil pipeline. At the same time, the fuel flowmeter can measure the return oil volume, so as to obtain a more accurate measurement value, improve the accuracy of return oil measurement, and solve the problem that usually the return oil volume inside the return oil barrel is directly used for measurement, while manual measurement has a large error and cannot accurately measure the return oil volume, which may affect the judgment of the ship fuel system by the staff and cannot meet the production requirements.

By providing the gas-liquid separation tank 2 and the oil inlet pipe 9, when the ship fuel enters the interior of the gas-liquid separation tank 2 through the oil inlet pipe 9, due to the action of gravity, the air in the ship fuel moves upward, and the ship fuel and other impurities fall downward. Then, by providing the exhaust pipe 8, the effect of gas-liquid separation of the ship fuel can be achieved.

[0025] In this embodiment, an oil return pipe 10 is fixedly connected to the bottom of the gas-liquid separation tank 2.

[0029] The working principle of the above embodiment is as follows:

[0030] First, the staff conveys the returned oil generated in the ship fuel system to the inside of the gas-liquid separation tank 2 through the inlet pipe 9. At this time, the returned oil is separated into gas and liquid due to the action of gravity, and the air will be discharged through the exhaust pipe 8. Subsequently, the oil pump 11 is started to convey the filtered returned oil to the inside of the returned oil barrel 14. During the conveying process, the fuel flowmeter 12 will measure the amount of returned oil in real time. At the same time, the fuel filter 15 will perform secondary filtration on the returned oil. The filtered returned oil can be collected by the returned oil barrel 14.
