Description

Technical Field

[0001] This invention relates to the field of oil and fat anti-oxidation storage, and particularly to an oil and fat anti-oxidation storage device and method. Background Technology

[0002] Oils and fats, such as lubricating oils and edible vegetable oils, require standardized storage and transportation by factories after production to ensure their quality during subsequent sales and use. During this process, oils and fats are highly susceptible to oxidation upon contact with oxygen in the outside air, leading to increased acid value and performance degradation.

[0003] In existing technologies, to prevent oil oxidation, negative pressure or a vacuum environment is often created by extracting gas from the storage tank to reduce the oxygen content inside the tank and thus lower the probability of oxidation. However, this solution has many shortcomings in practical applications and cannot meet the needs of efficient and convenient storage and use: Firstly, if the diameter of the tank outlet is small, the external atmospheric pressure will act in the opposite direction on the outlet when discharging, forming a pressure difference that hinders the smooth flow of oil. In particular, when extracting a small amount of oil, flow interruption is likely to occur, which seriously affects the oil extraction efficiency. Moreover, existing oil tanks are all cylindrical and have no cushioning structure, making them prone to damage from vibration and impact during transportation.

[0004] In the prior art, patent CN113044401A discloses a storage device that can prevent lubricating oil oxidation, including a bottle body and a cap. The bottle body has a neck and an oil outlet pipe. The upper end of the bottle body has an annular groove and an internal sealing ring. The cap has a stepped hole containing a lower vent hole and an upper threaded hole. The lower end of the cap abuts against the sealing ring, and the neck is fitted with the upper threaded hole. A sealing plate is provided on the top wall of the upper threaded hole. A controller and an air pump are installed on one side of the bottle body. The air pump is connected to the stepped hole through a vent pipe. Both the vent pipe and the oil outlet pipe are equipped with valves. Its basic principle is to achieve a double physical seal through the sealing ring and sealing plate, and then the air pump evacuates the lower vent hole to form a third seal, thereby enhancing the sealing performance and preventing lubricating oil oxidation. However, although this technology improves some of the original problems, it still has some shortcomings:

[0005] The existing equipment requires personnel to repeatedly open and close the bottle cap when storing and extracting oils, and a vacuum must be drawn each time the cap is opened, which is a cumbersome process. When the cap is opened to take out the oil, the remaining oil in the container will come into contact with the air, resulting in an oxidation reaction.

[0006] Therefore, based on the above-stated viewpoints, there is still room for optimization in the existing technology for the anti-oxidation storage of oils and fats. Summary of the Invention

[0007] To address the above problems, the present invention provides a storage device for preventing the oxidation of oils, comprising:

[0008] The main support frame consists of two symmetrically distributed rectangular frames and several support columns.

[0009] Several inclined columns are installed between the supporting columns.

[0013] Two push plates are symmetrically slidably installed inside the storage tank, dividing the inside of the storage tank into an input area, a storage area, and an output area from right to left. The input area and the output area correspond to the connecting pipes at the upper and lower ends, respectively.

[0014] A through-type component, mounted on the push plate, allows grease to pass through.

[0015] Vacuum components, installed on both sides of the storage tank, are used to evacuate the inside of the input and output areas.

[0016] Preferably, the valve assembly includes:

[0017] The support plate is installed inside the connecting pipe.

[0018] The sleeve is located at the upper end of the support plate.

[0019] A cylinder that slides up and down inside a sleeve.

[0020] A circular plate is installed at the upper end of the cylinder and corresponds to the inner wall of the connecting pipe.

[0021] The reset spring is installed between the cylinder and the inner bottom wall of the sleeve to apply a pushing force to the cylinder.

[0022] Preferably, the upper end of the circular plate has several transverse grooves distributed along its axis, and the inner wall of the connecting pipe has several longitudinal grooves that correspond one-to-one with the transverse grooves. The transverse grooves correspond to or are misaligned with the longitudinal grooves as the circular plate moves, thereby achieving sealing and opening / closing.

[0023] Preferably, the through-type component includes:

[0024] A square groove is formed on the inner wall of the storage tank, and the outer side of the push plate extends into the square groove and slides into it.

[0025] A rectangular groove is formed on the extension end of the push plate.

[0026] The rotating shaft is inserted into the rectangular slot by a torsion spring.

[0027] The flap is fitted onto the outside of the rotating shaft.

[0028] Preferably, the inner bottom wall of the rectangular groove is provided with an inclined surface that is inclined to the output area, and the end of the flap is adapted to the inclined surface, so that the flap can only swing in the direction of the output area.

[0029] Preferably, the vacuum assembly includes:

[0030] Two bending grooves are respectively opened inside the storage tank and correspond one-to-one with the connecting pipes. The ends of the bending grooves pass through the corresponding connecting pipes.

[0031] Two bent tubes are installed on the outside of the storage tank and are connected to the bending grooves one by one.

[0032] The series tube is connected in series in the middle of the bend tube, and one of the output ends of the series tube is used to connect to external vacuum equipment.

[0033] Preferably, the monitoring components include:

[0034] Two annular grooves are respectively opened at both ends of the storage tank.

[0035] The semi-circular plate is rotatably installed in the annular groove.

[0036] A semi-circular groove is formed on the annular groove and extends into the interior of the storage tank.

[0037] A transparent panel is installed inside a semi-circular groove.

[0038] Preferably, a handle is also installed on one side of the semicircular plate.

[0039] Preferably, in the main support frame, the rectangular frame is fixed to the support column by bolts, and the inclined column is also connected to the support column by bolts. The end of the inclined column away from the support column is fixed to the storage tank by bolts. The storage tank is protected against impact and buffered during transportation by the main support frame.

[0040] In addition, the present invention also provides a method for preventing the oxidation of oils and fats, comprising the following steps:

[0041] S1, Grease discharge: The external pipe is inserted into the upper connecting pipe, and the valve assembly is opened so that the external pipe can transport the grease through the connecting pipe to the input area.

[0042] S2, Grease Storage: One side pusher plate moves toward the input area, and the grease in the input area is squeezed into the storage area through the through component.

[0043] S3, Grease Discharge: The push plate on the other side moves toward the storage area, causing the grease in the storage area to move to the output area through the through component. Then the push plate moves toward the output area, driving the grease in the output area to be discharged to the outside of the storage tank through the connecting pipe.

[0044] S4, Grease Vacuum: In steps S2 and S3, when the valve assembly is opened, air from the external environment enters the input and output areas, and the air in the input and output areas is extracted by the vacuum assembly.

[0045] In summary, this application includes at least one of the following beneficial technical effects:

[0046] I. This invention uses a main support frame composed of a rectangular frame, support columns, and inclined columns. The rectangular frame serves as the foundation for a stable main body, while the inclined columns are used to fix the storage tank. This can buffer external vibrations and impacts during transportation, solving the problem of existing cylindrical oil tanks being easily damaged due to lack of buffering. It ensures the integrity of the tank and the safety of oil transportation, and prevents oil from leaking due to tank damage or oxidation upon contact with air.

[0047] Second, this invention divides the storage tank into an input area, a storage area, and an output area by cooperating with a push plate and a vacuum component. The oil flows in separate areas. During operation, the vacuum component only evacuates the air from the input and output areas, which can isolate the storage area from the air. There is no need to evacuate the entire tank, which solves the problem of large vacuum range and complicated steps in existing vacuuming methods. It also avoids the oxidation of residual oil during oil extraction, reduces the probability of increased acid value and performance degradation of the oil, and maintains the quality of the oil.

[0048] Third, this invention utilizes an automatic valve assembly, a supporting plate and sleeve in the connecting pipe, and other structural components. When the external pipe is inserted, it pushes the circular plate downward, aligning the horizontal and vertical grooves to allow grease to flow. After being pulled out, the reset spring causes the circular plate to reset and seal, eliminating the need for repeated opening and closing of the cover. This solves the problem of repeated opening and closing and re-vacuuming required for oil extraction, and also prevents the discharge from being interrupted due to pressure difference. This improves the convenience and efficiency of grease storage and extraction. Furthermore, the push plate applies pressure to the grease, which can smoothly drive the grease out of the connecting pipe, preventing pressure difference from hindering the smooth flow of grease.

[0062] The following combination Figures 1 to 11 The embodiments of the present invention will be described in detail below.

[0063] This application discloses an anti-oxidation storage device and method for oils and fats, which is applied to the anti-oxidation storage and extraction of lubricating oils, edible vegetable oils, etc. It can buffer and protect the storage tank through the main support frame, reduce the contact of oils and fats with air by the push plate and vacuum component to reduce the oxidation rate, and can also prevent the oxidation of residual oils and fats during oil extraction by the automatic opening and closing of the valve component, thereby improving convenience and efficiency.

[0064] Example 1: Refer to Figure 1 and Figure 2As shown, an oil anti-oxidation storage device includes a rectangular frame 1, support columns 10, inclined columns 11, a storage tank 12, a connecting pipe 13, a valve assembly 2, a push plate 14, an input area 15, a storage area 16, an output area 17, a through assembly 3, and a vacuum assembly 4. Two rectangular frames 1 are symmetrically distributed. At least four support columns 10 are fixedly installed between the rectangular frames 1 by bolts. The rectangular frames 1 and the support columns 10 together form the main support frame of this device. Several inclined columns 11 are installed between the support columns 10 by bolts. The storage tank 12 is fixedly installed at the end of the inclined columns 11 away from the support columns 10 by bolts. The storage tank 12 is fixed in the main support frame by several inclined columns 11. During transportation, the main support frame can also play a role in anti-collision and buffer protection for the storage tank 12.

[0065] The storage tank 12 has two staggered connecting pipes 13 inserted through its upper and lower ends. A valve assembly 2 is installed inside the connecting pipe 13 to open and close the inside of the connecting pipe 13. During use, grease is fed into the storage tank 12 from the upper connecting pipe 13 and then discharged to the outside of the storage tank 12 from the lower connecting pipe 13.

[0066] Two symmetrically distributed push plates 14 are symmetrically slidably installed inside the storage tank 12, and the push plates 14 are interference-fitted with the inner wall of the storage tank 12. The push plates 14 divide the internal area of ​​the storage tank 12 into an input area 15, a storage area 16 and an output area 17 from right to left. The input area 15 and the output area 17 correspond to the connecting pipes 13 at the upper and lower ends, respectively. The push plates 14 are provided with a through component 3 for allowing grease to pass through. Vacuum components 4 are also installed on both sides of the storage tank 12, corresponding to the input area 15 and the output area 17, and for evacuating the interior of the storage tank.

[0067] In addition, the present invention also provides a method for preventing the oxidation of oils and fats, comprising the following steps:

[0068] S1, Grease discharge: The external pipe is inserted into the upper connecting pipe 13, and the valve assembly 2 is opened so that the external pipe can transport the grease through the connecting pipe 13 to the input area 15.

[0069] S2, Grease storage: One side push plate 14 moves toward the input area 15, and the grease in the input area 15 is squeezed into the storage area 16 through the through component 3;

[0070] S3, Grease discharge: The push plate 14 on the other side moves toward the storage area 16, so that the grease in the storage area 16 moves to the output area 17 through the through component 3. Then the push plate 14 moves toward the output area 17 again, driving the grease in the output area 17 to be discharged to the outside of the storage tank 12 through the connecting pipe 13.

[0071] S4, Grease Vacuum: In steps S2 and S3, when valve assembly 2 is opened, air from the external environment enters the input area 15 and output area 17. The air in the input area 15 and output area 17 can be extracted by vacuum assembly 4. The storage area 16 is isolated by push plates 14 on both sides, so no air will enter.

[0072] Reference Figure 3 As shown, this is the valve assembly 2 used to open and close the interior of the connecting pipe 13. Specifically, the valve assembly 2 includes a support plate 20, a sleeve 21, a cylinder 22, a circular plate 23, a reset spring 24, a transverse groove 25, and a longitudinal groove 26. The support plate 20 is installed inside the connecting pipe 13. The upper end of the support plate 20 is provided with a sleeve 21. A cylinder 22 that can slide up and down is slidably inserted into the sleeve 21. A circular plate 23 corresponding to the inner wall of the connecting pipe 13 is installed on the upper end of the cylinder 22. A reset spring 24 for applying a pushing force to the cylinder 22 is installed between the cylinder 22 and the inner bottom wall of the sleeve 21. That is, the circular plate 23 is initially pushed and supported by the corresponding reset spring 24. When an external force is applied to the circular plate 23, the cylinder 22 can limit and guide its movement direction through the inner wall of the sleeve 21.

[0073] The upper end of the circular plate 23 has several transverse grooves 25 distributed along its axis, and the inner wall of the connecting pipe 13 also has several longitudinal grooves 26 corresponding to the transverse grooves 25. Therefore, in the initial state, when grease is to be input into the input area 15, the outer pipe is first inserted into the connecting pipe 13. The outer pipe contacts the upper end of the circular plate 23 and drives it to descend, so that the transverse grooves 25 correspond to the longitudinal grooves 26. Although the end face of the outer pipe is in contact with the upper end of the circular plate 23, the grease in the outer pipe can flow through the transverse grooves 25 into the longitudinal grooves 26, and then flow from the longitudinal grooves 26 into the input area 15. Similarly, when the grease in the output area 17 is to be discharged, the outer pipe is inserted into the lower end of the connecting pipe 13, driving the transverse grooves 25 and longitudinal grooves 26 on the circular plate 23 to communicate, so that the grease in the output area 17 can flow through the longitudinal grooves 26 and transverse grooves 25 into the outer pipe.

[0074] After the external tube is pulled out of the connecting tube 13, the circular plate 23 is pushed back to its original position by the corresponding reset spring 24. Since the horizontal groove 25 and the vertical groove 26 no longer correspond, the circular plate 23 can block the connecting tube 13 at this time to prevent external air from entering the input area 15 or the output area 17.

[0075] Reference Figure 4 and Figure 5As shown, this is the through-flow component 3 used to allow grease to pass through; specifically, the through-flow component 3 includes a square groove 30, a rectangular groove 31, a rotating shaft 32, a flap 33, and an inclined surface 34. The square groove 30 is formed on the inner wall of the storage tank 12, and the outer side of the push plate 14 also extends into the square groove 30 and slides into it. A rectangular groove 31 is formed on the extended end of the push plate 14, and the rotating shaft 32 is inserted into the rectangular groove 31 by a torsion spring. The flap 33 is sleeved on the outer side of the rotating shaft 32. From the above, it can be seen that when grease... After entering the input area 15, the air in the input area 15 is extracted by the vacuum assembly 4, so that the grease in the input area 15 no longer contains air. Then, the push plate 14 on one side moves toward the input area 15. At this time, the push plate 14 and the grease are squeezed. The squeezed grease drives the flip plate 33 and the rotating shaft 32 to flip, so that the grease in the input area 15 enters the storage area 16, completing the unified collection of grease. The torsion spring is used to make the flip plate 33 swing to the vertical position when it is not squeezed.

[0076] Similarly, when it is necessary to output the grease in the storage tank 12 to the outside of the storage tank 12, the push plate 14 on the other side moves towards the storage area 16, and then squeezes the grease in the storage area 16, causing the grease in the storage area 16 to enter the output area 17 through the flip of the corresponding flap 33. Then the push plate 14 moves in the opposite direction, pushing the grease to be discharged from the lower connecting pipe 13 to the outside of the storage tank 12. During this process, since air may be mixed into the input area 15 and the output area 17 due to the opening of the circular plate 23, and the storage area 16 is blocked by the two push plates 14, the air contained in the grease in the input area 15 and the output area 17 will not enter the grease stored in the storage area 16 during the grease input and output process. The vacuum component 4 only needs to perform vacuum extraction on part of the space in the input area 15 or the output area 17. The valve component 2 is used to prevent the grease from leaking out of the corresponding output pipe in advance when the push plate 14 moves.

[0077] Furthermore, an inclined surface 34 inclined to the output area 17 is provided on the inner bottom wall of the corresponding rectangular groove 31. That is, the end of the swing plate is also adapted to the corresponding inclined surface 34. The corresponding flap 33 can only swing towards the output area 17, so that the flap 33 can swing when the push plate 14 drives the grease to move from the input area 15 to the storage area 16, or from the storage area 16 to the output area 17. When the push plate 14 moves and squeezes towards the storage area 16, the flap 33 on the other side of the push plate 14 does not swing due to the resistance of the inclined surface 34. When the push plate 14 drives the grease in the output area 17 to move out of the output area 17 through the connecting pipe 13, its corresponding flap 33 will also be resisted by the inclined surface 34 and will not flip.

[0078] The push plate 14 applies pressure to the grease, which can smoothly drive the grease out of the connecting pipe 13 and prevent the pressure difference from hindering the smooth flow of the grease.

[0079] Continue to refer to Figure 3 and Figure 6 As shown, the vacuum assembly 4 corresponds to the input area 15 and the output area 17 and performs evacuation inside them. Specifically, the vacuum assembly 4 includes a bending groove 40, a bending tube 41, and a series tube 42. Two bending grooves 40 are respectively opened inside the storage tank 12 and correspond one-to-one with the connecting tubes 13. The ends of the bending grooves 40 penetrate into the corresponding connecting tubes 13. Two bending tubes 41 are installed on the outside of the storage tank 12 and are connected to the bending grooves 40 one-to-one. A series tube 42 is connected in series in the middle of the bending tubes 41. One output end of the series tube 42 is used to connect to the pumping port of an external vacuum device, so that the external vacuum device can perform evacuation operations on the areas in the input area 15 and the output area 17 through the cooperation of the series tube 42, the bending tube 41, and the bending groove 40.

[0080] Reference Figure 7 As shown, the monitoring component 5 is used to enable operators to observe the state of the grease inside the output area 17 and the input area 15 in real time. Specifically, the monitoring component 5 includes an annular groove 50, a semi-circular plate 51, a transparent plate 52, and a handle 53. The annular groove 50 is opened at both ends of the storage tank 12. The semi-circular plate 51 is rotatably installed in the annular groove 50, and a semi-circular groove penetrating into the interior of the storage tank 12 is also opened on the annular groove 50. The transparent plate 52 is installed in the semi-circular groove, and a handle 53 is installed on one side of the semi-circular plate 51. That is, the operator can observe the volume and state of the grease inside the input area 15 and the output area 17 through the transparent plate 52. Similarly, in special circumstances such as transportation, in order to prevent sunlight from shining on the grease through the transparent plate 52 and causing the grease to deteriorate, or to prevent the transparent plate 52 from breaking due to contact with foreign objects, the operator can drive the semi-circular plate 51 to rotate to correspond with the transparent plate 52 through the handle 53 to block and protect the transparent plate 52. When observation is needed, the semi-circular plate 51 can be rotated again to no longer block the transparent plate 52.

[0081] Example 2: Refer to Figure 8 and Figure 9As shown, based on Embodiment 1, a docking shaft 6 is also installed on the circular plate 23 inside the upper connecting pipe 13. That is, in actual use, in order to increase storage efficiency and capacity, multiple of this device can be connected together. Taking the connection of two of this device as an example, the two storage tanks 12 are placed one above the other, and the main frame is fixed together by bolts. The two storage tanks 12 face opposite directions, so that the connecting pipe 13 at the upper end of the lower storage tank 12 can be connected to the connecting pipe 13 at the lower end of the upper storage tank 12. Then, the docking shaft 6 of the upper circular plate 23 will be inserted into the corresponding connecting pipe 13, so that the circular plates 23 in the two connecting pipes 13 move towards the corresponding sleeve 21, further enabling the two connecting pipes 13 to communicate with each other. The output area 17 and the input area 15 in the two storage tanks 12 are connected, so that the grease can circulate and be stored between multiple storage tanks 12.

[0082] Example 3: Refer to Figure 10 and Figure 11 As shown, based on Embodiment 1 and Embodiment 2, in order to move the push plate 14, a drive assembly 7 is installed between the support columns 10. Specifically, the drive assembly 7 includes a drive slot 70, an electromagnet 71, a strong magnet 72, a motor frame 73, a drive motor 74, and a drive screw 75. Two symmetrically distributed drive slots 70 are opened on the outside of the storage tank 12. An electromagnet 71 is slidably installed in the drive slot 70, and a strong magnet 72 is also installed on the outside of the push plate 14 corresponding to the drive slot 70. That is, when the external electromagnet 71 moves, the strong magnet 72 and the corresponding push plate 14 can be moved by magnetic force.

[0083] Two sets of motor frames 73 are respectively installed between the corresponding upper and lower support columns 10 on the corresponding side. A drive motor 74 is installed between the motor frames 73. The main shaft of the drive motor 74 is equipped with a drive screw 75 through a coupling. The end of the drive screw 75 passes through the middle of the electromagnet 71 and is threadedly connected to it.

[0084] The motor frame 73 is used to support the drive motor 74, and the main shafts of the two drive motors 74 are not aligned, each facing the push plate 14 on the corresponding side. The drive motor 74 drives the electromagnet 71 to move in the drive groove 70 through the drive screw 75, thereby driving the push plate 14 to move. Furthermore, when the push plate 14 moves in the storage tank 12, since the outer side of the push plate 14 is in contact with the inner wall of the storage tank 12, it can scrape and remove the grease adhering to the inner wall of the storage tank 12.

[0085] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and not restrictive.

[0086] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
