During long-term storage, white oil is prone to stratification or sedimentation due to gravity, leading to a decline in its quality. Therefore, its storage requires consideration of ease of loading and unloading, fire safety, and sedimentation issues. Traditional white oil storage tanks suffer from problems such as inconvenient loading and unloading, insufficient fire protection measures, and severe sedimentation, affecting storage efficiency and safety. Utility Model Content

[0003] The purpose of this utility model is to provide a white oil storage tank that solves the problems of white oil sedimentation, inconvenient loading and unloading, and insufficient safety in the prior art by optimizing the design of the tank structure, anti-settling components, loading components, and unloading components.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A white oil storage tank includes a tank body, an anti-sinking component, a feeding component, and a discharging component. The tank body includes an intermediate tank body, a tank bottom integrally formed at the lower end of the intermediate tank body, and a top cover installed at the upper end of the intermediate tank body. The anti-sinking component includes a baffle and a stirrer. The baffle is disposed on the inner wall of the intermediate tank body along the axial direction. The stirrer includes a rotating shaft disposed in the intermediate tank body and a stirring part. The stirring part consists of multiple layers of stirring blades. The multiple layers of stirring blades are distributed axially on the rotating shaft, and each layer of stirring blades is composed of multiple sets of helical blades surrounding the outer periphery of the rotating shaft.

[0006] Furthermore, the intermediate tank is a vertical cylindrical structure with a length-to-diameter ratio of 1:1 to 3:1, and the bottom of the tank is conical or dish-shaped.

[0007] Furthermore, the number of baffles is 4 to 6 and they are evenly distributed on the inner circumferential surface of the intermediate tank. The lower end of the baffle extends to the top of the tank bottom. The shape of the baffle is rectangular, and the width of the baffle is 1:12 to 1:10 of the diameter of the intermediate tank.

[0008] Furthermore, the surface of the baffle is provided with an uneven structure, and the edge of the baffle is smoothly transitioned.

[0009] Furthermore, the stirrer also includes a drive motor, which is mounted on the upper cover. The rotating shaft passes through the upper cover and is connected to the output end of the drive motor. The axial direction of the rotating shaft coincides with the axial direction of the intermediate tank.

[0010] Furthermore, each layer of stirring blades is composed of 3 to 5 sets of helical blades surrounding the outer periphery of the rotating shaft, and the outer ends of the helical blades along the extension direction are pointed.

[0011] Furthermore, the feeding assembly includes a feed inlet, a quick connector, and a filter. The feed inlet is located on the upper cover, the quick connector is installed inside the feed inlet and connected to an external feed pipe, and the filter is installed inside the quick connector.

[0012] Furthermore, the feeding assembly includes a discharge port, a discharge pipe, a flow meter, and an emergency shut-off valve.

[0015] The beneficial effects of this utility model are:

[0016] 1. The multi-layered stirring blade design enables the stirrer to generate stirring force at different depths, ensuring that all layers of white oil in the tank are fully stirred and avoiding stratification. At the same time, the stirring blade design can generate strong shearing force to break up the sediment in the white oil and prevent it from re-aggregating. The baffle design can effectively break the formation of vortices during the stirring process, ensuring that the white oil is evenly mixed throughout the tank and avoiding insufficient stirring and sedimentation problems caused by vortex effect.

[0017] 2. The filter in the feeding assembly can effectively filter impurities in the feed, ensuring the purity of the white oil and preventing impurities from damaging the internal structure of the storage tank and the agitator.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] like Figures 1 to 3 As shown, this embodiment of the utility model provides a white oil storage tank, including a tank body 10, an anti-sinking component 20, a feeding component 30, and a discharging component 40. A support frame 17 is also installed at the lower end of the tank body 10. The tank body 10 includes a vertical cylindrical intermediate tank body 11, a tank bottom 13 integrally formed at the lower end of the intermediate tank body 11, and an upper cover 12 installed at the upper end of the intermediate tank body 11. The feeding component 30 is installed on the upper cover 12, the discharging component 40 is connected to the tank bottom 13, and the anti-sinking component 20 is disposed in the inner cavity of the intermediate tank body 11.

[0034] In this invention, the length-to-diameter ratio of the intermediate tank 11 is designed to be 1:1 to 3:1. The cylindrical tank is subjected to uniform stress, which effectively reduces stress concentration and improves the strength and safety of the tank. The height-to-diameter ratio of the tank is rationally designed to avoid excessive height leading to sediment accumulation. At the same time, a certain amount of space is reserved inside the tank to accommodate the expansion of white oil due to temperature changes. The tank bottom 13 is designed as a cone or dish shape to facilitate the centralized discharge of white oil and reduce residue. Specifically, in this embodiment, the length-to-diameter ratio of the intermediate tank 11 is designed to be 2:1, and the tank bottom 13 is designed as a dish shape.

[0035] In this embodiment, the anti-settling component 20 includes four rectangular baffles 21 and a stirrer. The four baffles 21 are evenly distributed along the axial direction of the intermediate tank 11 on the inner circumferential surface of the intermediate tank 11. In the white oil storage tank, the main function of the baffles 21 is to prevent the formation of vortices in the white oil during stirring, thereby promoting uniform mixing of the liquid in the tank and avoiding insufficient stirring and sedimentation problems caused by the vortex effect. In addition, the baffles 21 can also enhance the stirring effect of the stirring blades 23 and improve the stirring efficiency. This layout can effectively break the formation of vortices during stirring and ensure uniform mixing of the white oil throughout the tank.

[0036] Specifically, the baffle 21 is fixed to the inner wall of the tank by welding. The width of the baffle 21 is 1:12 of the diameter of the intermediate tank 11. The lower end of the baffle 21 extends to the top of the tank bottom 13. The surface of the baffle 21 has a concave-convex structure, and the edges of the baffle 21 are smoothly transitioned. This size design effectively prevents vortex formation without excessively hindering the movement of the stirring blades 23. The surface of the baffle 21 is designed with a small concave-convex structure to increase the turbulence effect of the liquid, thereby improving the mixing efficiency. In addition, the edges of the baffle 21 are designed with a smooth transition to reduce resistance and eddies during liquid flow.

[0037] In this embodiment, the agitator includes a drive motor 24, a rotating shaft 22, and a stirring section. The drive motor 24 is mounted on the upper cover 12, and the rotating shaft 22 and the stirring section are disposed inside the intermediate tank 11. The rotating shaft 22 passes through the upper cover 12 and is connected to the output end of the drive motor 24. The axial direction of the rotating shaft 22 coincides with the axial direction of the intermediate tank 11. The stirring section consists of two layers of stirring blades 23, which are distributed axially on the rotating shaft 22. Specifically, each layer of stirring blades 23 is composed of three sets of helical blades 231 surrounding the outer periphery of the rotating shaft 22, and the outer ends of the helical blades 231 are pointed along the extension direction. In this embodiment, the multi-layered stirring blades 23 of the agitator are distributed axially along the rotating shaft 22, and each layer of stirring blades 23 is composed of three sets of helical blades 231, which can achieve uniform stirring of the entire tank. The pointed outer ends of the helical blades 231 can generate strong eddies and shear forces during stirring, breaking down the sediment in the white oil, preventing it from re-aggregating, and further enhancing the stirring effect. In other embodiments, the stirring blades 23 may be configured as three or four layers as needed.

[0038] In this embodiment, the feeding assembly 30 includes a feed inlet 31, a quick connector 32, and a filter 33. The feed inlet 31 is located on the top cover 12, and the quick connector 32 is installed inside the feed inlet 31 and connected to an external feed pipe via a flange. The filter 33 is a barrel-shaped structure with filter holes, which is snapped into the quick connector 32 for easy disassembly and replacement. The filter 33 in the feeding assembly 30 can effectively filter impurities in the feed, ensuring the purity of the white oil and preventing impurities from damaging the internal structure of the storage tank and the agitator.

[0039] In this embodiment, the feeding assembly 40 includes a discharge port, a discharge pipe 41, a flow meter 42, and an emergency shut-off valve 43. The discharge port is located at the bottom 13 of the tank, and the discharge pipe 41 is connected to the discharge port. The flow meter 42 and the emergency shut-off valve 43 are installed on the discharge pipe 41. The pipe connection is seamlessly welded to ensure the sealing and strength of the connection and prevent leakage. The flow meter 42 and the emergency shut-off valve 43 installed on the discharge pipe 41 enable control of the white oil flow and rapid shut-off in emergencies.

[0040] In this embodiment, a pressure sensor 15 and a safety valve 16 are also installed on the top cover 12 to monitor the pressure inside the tank in real time. When the pressure exceeds the set value, the safety valve 16 automatically opens to release excess pressure and prevent the tank from exploding due to excessive pressure.

[0041] In this embodiment, a level gauge 14 is installed on the side wall of the intermediate tank 11 to display the real-time level of the white oil inside the tank. The level gauge 14 can be connected to the control system to realize automatic alarm and automated control of feeding and discharging, avoiding safety problems caused by excessively high or low liquid levels.

[0042] In this embodiment, the tank bottom 13 is also equipped with an emergency discharge pipe, which connects to a collection pool in a safe area; the outer surface of the tank body 10 is coated with an intumescent fire-retardant coating. The emergency discharge pipe can quickly discharge the white oil inside the tank in an emergency to prevent accidents; the fire-retardant coating can form a heat insulation layer under high temperature or fire conditions, delaying the spread of fire and protecting the tank structure. Through their unique functions and synergistic effects, the emergency discharge pipe and the fire-retardant coating significantly improve the safety and fire resistance of the storage tank.

[0043] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
