[0002] In industrial production and machinery operation, the oil tank is a crucial component for storing hydraulic fluids. However, due to various reasons, moisture inevitably gets into the oil tank. The presence of moisture causes oil emulsification, reducing the oil's lubricating and rust-preventing properties, accelerating equipment wear and corrosion, and severely impacting the normal operation and service life of the equipment. Therefore, timely and effective drainage of moisture from the oil tank is essential.

[0003] Currently, fuel tank drainage is mainly done manually on a regular schedule. This method is not only labor-intensive, but also prone to water accumulation in the tank due to untimely drainage, affecting fuel quality. Furthermore, manual drainage also suffers from inconvenience and low efficiency.

[0004] To address the aforementioned issues, an automatic fuel tank drainage device is proposed. Utility Model Content

[0010] When the float is positioned above the inlet and between the liquid level in the tank, the float valve is in the open state; when the float is positioned below the inlet, the float valve is in the closed state.

[0011] Furthermore, the housing and the connecting pipe are lined with an inner membrane of corrosion-resistant material.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0027] like Figure 1 As shown, this utility model provides a technical solution: an automatic oil tank drainage device, including an oil tank body 1, a connecting pipe and an oil-water separator; the oil-water separator is composed of a tank body 2 and a valve control device, wherein: the tank body 2 is provided with a water inlet 3, a drain outlet 4 and an oil inlet 5, the valve control device is installed inside the tank body 2 and connected to the drain outlet 4, and the valve control device controls the drain outlet 4 to open and close according to the actual liquid level.

[0028] The connecting pipe includes a first connecting pipe 6 and a second connecting pipe 7; the upper end of the oil tank body 1 is provided with an oil outlet 8 and the lower end is provided with a water outlet 9; the oil outlet 8 is connected to the oil inlet 5 through the first connecting pipe 6, and the water outlet 9 is connected to the water inlet 3 through the second connecting pipe 7.

[0029] Based on the density difference between oil and water, the water in the oil tank body 1 will settle at the bottom. The oil and water are transported to the tank body 2 of the oil-water separator through the first connecting pipe 6 and the second connecting pipe 7 respectively. The water will accumulate in the tank body 2. When the water level rises to a designated position, the valve control switch will automatically start, controlling the drain outlet 4 to open, thereby realizing the discharge of water. When the water level drops to a certain level, the valve control switch controls the drain outlet 4 to close, stopping the drainage.

[0030] Preferably, in this embodiment, the valve control device comprises a buoyancy adjusting block 10, a float 11, a float valve lever 12, and a float valve 13; wherein, the buoyancy adjusting block 10 is mounted on the float 11 and is used to adjust the buoyancy of the float 11; the fixed end of the float valve lever 12 is connected to the float 11, and the working end of the float valve lever 12 is connected to the float valve 13; the float valve 13 is mounted at the drain outlet 4; and the float valve lever 12 is used to control the opening and closing of the float valve 13, thereby controlling the opening and closing of the drain outlet 4.

[0031] As water accumulates in tank 2, the buoyancy of float 11 gradually increases with the rise in water level. When the water level reaches a certain level, float 11 drives float valve 13 to open via float valve lever 12, allowing water to drain from float valve 13. When the water level drops to a certain level, the buoyancy of float 11 decreases, and float valve lever 12 drives float valve 13 to close, stopping drainage. The advantages of the above valve control device are its simple structure, convenient installation, low maintenance cost, wide applicability, and suitability for various types of oil tanks.

[0032] When the float 11 is located above the inlet 3 and between the liquid level inside the tank 2, the float valve 13 is in the open state; when the float 11 is located below the inlet 3, the float valve 13 is in the closed state.

[0033] To prevent the float valve 13 from being in the open state when the float ball 11 is below the water inlet 3, thereby avoiding losses.

[0034] The valve control device is not limited to the valve control device mentioned above; it only needs to be able to automatically control the drain outlet 4 according to the rise and fall of the liquid level.

[0035] Preferably, in this embodiment, the housing 2 and the connecting pipe are lined with an inner membrane of corrosion-resistant material to extend the service life of the device.

[0036] Preferably, in this embodiment, a level gauge 14 is also connected to the outside of the box 2 for observing the water level of the liquid inside the box 2.

[0037] The liquid level in the tank 2 can be observed at any time by the liquid level gauge 14. When the liquid level exceeds the specified position and the valve control device is not activated, the device can be manually inspected at any time to avoid greater losses.

[0038] Preferably, a first valve 15 and a second valve 16 are respectively installed on the first connecting pipe 6 and the second connecting pipe 7.

[0039] The first valve 15 and the second valve 16 control the first connecting pipe 6 and the second connecting pipe 7 respectively, thereby controlling the outflow of oil and water in the oil tank body 1, ensuring that the start-up and shutdown of the device are controllable, and preventing the device from still being in working state after the water is discharged, thus avoiding the loss of oil in the oil tank body 1.

[0040] Preferably, the buoyancy adjustment block 10 is detachably connected to the float 11, so that the installation position of the buoyancy adjustment block 10 on the float can be changed.

[0041] Based on oils of different densities, the buoyancy of the float 11 is adjusted by changing the position of the buoyancy adjustment block 10 on the float 11 to adapt to oils of different densities and improve the applicability of the device.

[0042] More preferably, the float 11 is fixedly connected to the float valve lever 12, or the float 11 and the float valve lever 12 are an integral structure.

[0043] Improve the connection between float 11 and float valve lever 12, convert the buoyancy force on float 11 into the power of float valve lever 12, and prevent float 11 and float valve lever 12 from separating due to the force, thus making it impossible to control the opening and closing of drain port 4.

[0044] Preferably, the float valve lever 12 and the float valve 11 are connected by a rotating shaft 17. The float valve lever 12 rotates around the rotating shaft 17, thereby driving the float valve 11 to rise and fall, so that the rise and fall of the float valve 11 has better continuity and improves the sensitivity of the device.

[0045] Preferably, the first connecting pipe 6 is connected to the oil outlet 8 and the oil inlet 5 respectively via connectors; the second connecting pipe 7 is connected to the water outlet 9 and the water inlet 3 respectively via connectors; the connector structure improves the sealing of oil and water during the transportation process in the first connecting pipe 6 and the second connecting pipe 7, and avoids oil loss during the transportation process.

[0046] The specific process of using this device to drain water from the oil tank is as follows:

[0047] During the preparation stage, the position of the buoyancy regulating block 10 on the float 11 is adjusted according to the oil density. The first valve 15 and the second valve 16 are opened. During the operation stage, the oil and water in the oil tank body 1 flow into the tank body 2 of the oil-water separator through the first connecting pipe 6 and the second connecting pipe 7, respectively. Water will accumulate in the tank body 1. As the water level rises, the buoyancy of the float 11 gradually increases. When the water level rises to the designated position, the float 11 rises due to its own buoyancy, which in turn drives the float valve lever 12 to rotate around the rotating shaft 17, thereby controlling the float valve 13 to rise and allowing water to be discharged from the drain outlet 4. When the water level drops to a certain level, the float 11 falls with the liquid level, which in turn drives the float valve lever 12 to rotate in the opposite direction, controlling the float valve 13 to fall, thereby closing the drain outlet 4 and stopping the drainage. In addition, the liquid level in the tank body 2 can be observed through the liquid level gauge 14, and the operation of the device can be stopped manually at any time to avoid losses.

[0048] In summary, this utility model achieves the following technical effects:

[0049] 1) This utility model uses the first connecting pipe 6 and the second connecting pipe 7 to transport oil and water from the oil tank body 1 to the tank body 2, thereby improving the liquid transport efficiency.

[0050] 2) This utility model achieves oil-water separation through an oil-water separator. Specifically, the position of the buoyancy adjustment block 10 on the float 11 is adjusted, thereby changing the buoyancy of the float 11. The float 11 drives the float valve lever 12 to rotate around the rotating shaft 17, thereby driving the float valve 13 to rise and fall, controlling the discharge of water. While improving the applicability of the device to oils of different densities, the structure of this oil-water separator is relatively simple, making maintenance more convenient. It drains water in a timely and efficient manner, effectively ensuring the cleanliness of the oil in the tank.

[0051] 3) This utility model connects a level gauge 14 to the oil-water separator to observe the changes in the liquid level in the tank 2 at any time. When the device is damaged, it can be observed at any time, so as to repair it in time and reduce losses.

[0052] 4) The present invention has a corrosion-resistant inner membrane lining both the housing 2 and the connecting pipe to prevent oil from corroding the housing 2 and the connecting pipe, thereby improving the service life of the device.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
