[0002] In existing vegetable oil storage technologies, traditional rapeseed oil storage equipment has many shortcomings, mainly in the following aspects: Poor drainage: Traditional tank bottom plates are mostly horizontally designed, and the position of the oil drain hole is not optimized. Rapeseed oil is difficult to completely drain under gravity, resulting in a large amount of residue at the bottom of the tank and waste of oil.

[0003] The storage tanks are not easy to move. Most of them are fixed installation structures and lack convenient moving functions. When switching between oil pressing, storage and transportation scenarios, the operation is cumbersome and the flexibility is low.

[0004] Pressure cannot be monitored. When the pressure inside the tank changes with temperature or fluctuates with the sealing status, it is impossible to detect abnormal pressure in real time. Excessive pressure may cause the tank to deform or leak, posing a safety hazard.

[0005] The operation is labor-intensive, the tank top height is fixed, and operations such as oil filling and cleaning require manual climbing or the use of auxiliary tools. In addition, the internal space of the tank cannot be flexibly adjusted, and its ability to adapt to different oil storage volumes is weak. Utility Model Content

[0010] As a preferred embodiment of this utility model, the inner wall of the tank is provided with raised guide ribs in the vertical direction, and the edge of the movable tank top plate is provided with guide grooves that match the guide ribs.

[0011] As a preferred embodiment of this utility model, the movable support frame includes a support plate, several vertical support columns and a horizontal connecting rod.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] like Figure 1-5 As shown, this utility model provides a storage tank for rapeseed oil, including a tank cylinder 1, a tank bottom plate 2, a movable tank top plate 3, and a movable support frame 4; like Figure 2 As shown, the bottom of the tank cylinder 1 is fixedly and sealed to the edge of the tank bottom plate 2. The tank cylinder 1 serves as the main cavity for storing rapeseed oil and has a vertical cylindrical structure. The tank bottom plate 2 is installed on the top of the movable support frame 4, and the bottom of the movable support frame 4 is equipped with movable wheels 5. like Figure 5 As shown, the movable tank top plate 3 is movably mounted on the inner wall of the tank cylinder 1, and the edge of the movable tank top plate 3 abuts and seals against the inner wall of the tank cylinder 1. The inner wall of the tank cylinder 1 has raised guide ribs 12 in the vertical direction, and the edge of the movable tank top plate 3 has guide grooves 13 that match the guide ribs 12. The guide ribs 12 and guide grooves 13 ensure that the movable tank top plate 3 moves stably in the vertical direction during lifting and lowering, avoiding tilting or jamming, and ensuring sealing effect and structural safety.

[0021] like Figure 1 As shown, an oil injection hole 6 is provided through the top plate 3 of the movable tank, and an oil injection pipe 7 with a valve is provided at the top of the oil injection hole 6; an oil drain hole 8 is provided through the bottom of the tank cylinder 1, and an oil drain pipe 9 with a valve is provided on the outside of the oil drain hole 8.

[0022] Regarding the oil injection pipe 7, an oil injection hole 6 is drilled through the top plate 3 of the movable tank. The top of the oil injection hole 6 is fixedly connected to the oil injection pipe 7 with a valve. The valve is manually controlled, such as a ball valve or gate valve. When injecting oil, the valve is opened, and rapeseed oil flows into the tank through the oil injection pipe 7 and the oil injection hole 6. After the oil injection is completed, the valve is closed to prevent oil from overflowing and air from entering. The oil injection hole 6 is located at the highest point of the bottom surface of the top plate 3 of the movable tank, adapted to the inclined surface design of the top plate, ensuring that the oil naturally diffuses along the inclined surface during injection, reducing residual air in the tank.

[0023] Regarding the drain pipe 9, a drain hole 8 is opened through the bottom of the tank 1, and a drain pipe 9 with a valve is fixedly connected to the outside of the drain hole 8. The valve is also manually controlled. When draining oil, the valve is opened, and the rapeseed oil in the tank is discharged through the drain hole 8 and the drain pipe 9 under the action of gravity. After draining oil, the valve is closed to achieve sealed storage. The drain hole 8 is located at the lowest position on the top surface of the tank bottom plate 2, which is adapted to the inclined surface design of the bottom plate to ensure that the oil is completely discharged.

[0024] Specifically, such as Figure 1 As shown, the bottom surface of the movable tank top plate 3 and the top surface of the tank bottom plate 2 are matched inclined surfaces. The drain hole 8 is located at the lowest point of the top surface of the tank bottom plate 2, and the filling hole 6 is located at the highest point of the bottom surface of the movable tank top plate 3. The core advantage of this design is to improve the oil drainage efficiency: with the top surface of the tank bottom plate 2 inclined and the drain hole 8 located at the lowest point, the rapeseed oil naturally gathers towards the drain hole 8 under the action of gravity, significantly reducing the amount of oil remaining at the bottom of the tank. With the bottom surface of the movable tank top plate 3 inclined and the filling hole 6 located at the highest point, the oil can evenly fill the space inside the tank along the inclined surface during oil filling, avoiding storage hazards caused by localized air accumulation. The inclined surface, combined with the lifting and lowering action of the movable tank top plate 3, allows the residual oil to be squeezed out by the lowering of the top plate in the later stages of oil drainage, further improving the drainage effect and increasing the oil utilization rate.

[0025] Specifically, a pressure measuring hole 10 is also provided through the top plate 3 of the movable tank. A pressure gauge 11 is installed inside the pressure measuring hole 10. The sensing end of the pressure gauge 11 extends into the tank cylinder 1, and the display end of the pressure gauge 11 is located at the top of the top plate 3 of the movable tank. By monitoring the pressure in real time through the sensing end of the pressure measuring hole 10 extending into the tank cylinder 1, and the display end being located at the top of the top plate 3 of the movable tank, pressure abnormalities caused by temperature changes or excessive sealing can be detected in a timely manner, preventing leakage or structural damage caused by excessive pressure inside the tank.

[0026] The movable tank top plate 3 is equipped with a drive mechanism, such as... Figure 3 and 4As shown, the drive mechanism includes a vertical drive column 17, a horizontal drive rod 18, two electrically driven movable bases 19, and two track support plates 20. The bottom end of the vertical drive column 17 is fixedly connected to the center of the top surface of the movable tank top plate 3, and the top end of the vertical drive column 17 is perpendicularly connected to the center of the horizontal drive rod 18. Both ends of the horizontal drive rod 18 are fixedly connected to one end of each of the two electrically driven movable bases 19. The bottom ends of the two track support plates 20 are fixedly connected to both ends of the outer wall of the tank 1. The inner side of the track support plate 20 is equipped with vertical guide rails 21 that match the electrically driven movable bases 19, and the two electrically driven movable bases 19 are slidably connected to the two vertical guide rails 21. A structurally stabilizing horizontal connecting rod 22 is also connected between the top ends of the two track support plates 20, which enhances the overall structural stability of the drive mechanism and prevents the track support plates 20 from deforming during long-term use. Several diagonal braces 23 are evenly connected between the vertical drive column 17 and the top surface of the movable tank top plate 3. The diagonal braces 23 can enhance the connection strength between the vertical drive column 17 and the top plate and prevent uneven force on the top plate during the driving process.

[0027] The working principle of the drive mechanism is as follows: the electrically driven movable base 19 slides along the vertical guide rail 21 inside the track support plate 20, and drives the vertical drive column 17 to rise and fall through the horizontal drive rod 18, ultimately driving the movable tank top plate 3 to move vertically along the inner wall of the tank cylinder 1, realizing the adjustment and sealing control of the tank space. When oil needs to be added, the electrically driven movable base 19 moves upward along the vertical guide rail 21, and drives the movable tank top plate 3 to rise through the horizontal drive rod 18 and the vertical drive column 17, increasing the tank space; after oil addition is completed, the base moves downward along the guide rail, and the top plate descends to fit against the oil surface to achieve a seal. When oil needs to be drained, the top plate can gradually move downward as the oil surface descends, squeezing the oil to accelerate the emptying.

[0028] More specifically, the electrically driven moving base 19 can adopt a small gear and rack type electric slider, such as the electric guide rail slider of model SL-100, and the vertical guide rail 21 is a matching rack rail; after the electrically driven moving base 19 is powered on, the internal motor drives the gear to rotate along the rack, which drives the base to move vertically along the guide rail, thereby realizing the automatic lifting and lowering of the movable tank top plate 3 and reducing the intensity of manual operation.

[0029] The movable support frame 4 includes a support plate 14, several vertical support columns 15, and horizontal connecting rods 16. The top ends of the vertical support columns 15 are vertically fixed to the bottom edge of the support plate 14. The two ends of the horizontal connecting rods 16 are connected between the sides of two adjacent vertical support columns 15. The bottom ends of the vertical support columns 15 are connected to the top ends of the movable wheels 5. The movable wheels 5 are lockable omnidirectional wheels. The vertical support columns 15 and the horizontal connecting rods 16 combine to form a stable support structure. The bottom movable wheels 5 are lockable omnidirectional wheels, which not only facilitate the flexible movement of the tank between the oil pressing area, storage area, and other scenarios, but also fix the position through the locking function to prevent accidental slippage.

[0030] The edge of the movable tank top plate 3 and the inner wall of the tank cylinder 1 adopt a contact sealing structure, achieving an initial seal through their tight fit. Simultaneously, the inner wall of the tank cylinder 1 has raised guide ribs 12 arranged vertically, and the edge of the movable tank top plate 3 has corresponding guide grooves 13 that match the guide ribs 12. The sliding fit between the guide ribs 12 and the guide grooves 13 not only limits the horizontal displacement of the movable tank top plate 3 but also further enhances the tightness of the fit between the edge and the inner wall, effectively preventing rapeseed oil leakage and ensuring airtightness during storage.

[0031] The principle of this utility model is as follows: the tank cylinder 1 and the tank bottom plate 2 are sealed to form a storage cavity, the movable tank top plate 3 is raised and lowered along the inner wall of the tank cylinder 1 to adjust the cavity space and seal it; oil is injected into the tank through the oil injection pipe 7 and rapeseed oil is discharged through the oil drain pipe 9; the pressure gauge 11 monitors the pressure inside the tank in real time, the movable support frame 4 realizes the overall movement, and the drive mechanism controls the raising and lowering of the movable tank top plate 3.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
