Description

Technical Field

[0001] This utility model belongs to the field of oil storage tank technology, and specifically relates to an oil tank for preventing the oxidation of vegetable oil. Background Technology

[0002] Oil storage tanks, also known simply as oil tanks or storage tanks, are large, regularly shaped containers used to store oil products. They can be categorized into metal tanks and non-metal tanks based on their construction materials. Metal tanks are mostly made of steel and are the most common type used in oil depots. Non-metal tanks, also known as "makeshift tanks," are used to store crude oil or other petroleum products due to their lower safety standards. They are used in refineries, oil fields, oil depots, and other industries. A tank farm consists of multiple tanks. Each tank farm typically stores one type of oil product.

[0003] A search revealed Chinese patent CN214421355U, which discloses a storage device for vegetable oil production. The device includes a feeding structure, a fixing structure, a moving structure, and a storage unit. The fixing structure comprises a fixing frame, a winding column, a fixing block, a stabilizing telescopic column, bolts, and clamping plates. The winding column is installed at the top of the fixing frame. The fixing frame and the fixing block are fixed together by bolts. The stabilizing telescopic column is installed on one side of the fixing frame via the fixing block. Clamping plates are installed on both sides of the fixing frame. The baffles and clamping slots effectively prevent the entry of other substances, thus preventing oxidation and deterioration. The screws on the frame allow users to easily inspect and clean the storage tank. The stabilizing telescopic column and frame can accommodate many different oil tanks, achieving high compatibility. The casters and handles make it easier and more convenient for users to move the tank.

[0004] However, in actual use, it has been found that as the oil tank is used, the vegetable oil inside is gradually emptied, and the inside of the oil tank will contain a large amount of air. Vegetable oil contains a large amount of unsaturated fatty acids, such as oleic acid, linoleic acid and linolenic acid. When there is air in the oil tank, the oxygen in the air will react with these unsaturated fatty acids to cause the oil to oxidize and become rancid. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an oil tank that prevents the oxidation of vegetable oil.

[0006] To achieve the above objectives, this utility model provides an oil tank for preventing the oxidation of vegetable oil, comprising a storage tank, a support fixedly installed at the bottom of the storage tank, a cap fixedly installed at the top of the storage tank, an outlet at the bottom of the storage tank, evenly distributed guide rails fixedly connected inside the storage tank, a movable plate slidably connected to the outer wall of the guide rails, a sealing ring sleeved on the edge of the movable plate, an insert rod fixedly connected to the central axis of the movable plate, the insert rod penetrating and extending to the top of the cap, a fixing sleeve fixedly connected to the central axis of the cap, the fixing sleeve sleeved on the outer wall of the insert rod, a sliding plate fixedly connected to the top of the insert rod, and slide rails fixedly connected to both sides of the storage tank, with the sliding plate sliding inside the slide rails.

[0007] In the above technical solution, a bottom plate is fixedly connected to the movable plate, a top plate is fixedly connected to the bottom of the cover, and a telescopic sleeve is fixedly connected between the top plate and the bottom plate.

[0008] In the above technical solution, a counterweight is further fixedly connected to the top of the movable plate.

[0009] In the above technical solution, the inner side of the slide plate is further provided with uniformly distributed quantitative patterns.

[0010] In the above technical solution, push-pull plates are further fixedly connected to both ends of the skateboard.

[0011] In the above technical solution, an inlet pipe is further provided at the bottom of the side wall of the storage tank.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The vegetable oil inside the storage tank is supported by a movable plate. As the flow rate inside the storage tank decreases, the movable plate descends synchronously to ensure contact with the oil surface, thereby preventing the vegetable oil from contacting air. This design effectively extends the shelf life of the vegetable oil and ensures its quality. At the same time, because the movable plate can always be in contact with the oil surface, it can prevent the vegetable oil inside from creating waves during movement, further slowing down the oxidation process of the vegetable oil, reducing the rate of rancidity, and thus reducing the generation of waste oil.

[0014] As the movable plate slides downwards, the bottom plate gradually moves away from the top plate, and the corresponding stretching sleeve occupies the space inside the storage tank, thereby further reducing the oxidation process of the vegetable oil. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-4 The illustrated oil tank for preventing vegetable oil oxidation includes a storage tank 1, a support 2 fixedly installed at the bottom of the storage tank 1, a cap 4 fixedly installed at the top of the storage tank 1, an outlet 11 at the bottom of the storage tank 1, and evenly distributed guide rails 12 fixedly connected inside the storage tank 1. A movable plate 18 is slidably connected to the outer wall of the guide rails 12, and a sealing ring 13 is fitted around the edge of the movable plate 18. An insert rod 5 is fixedly connected to the central axis of the movable plate 18, and the insert rod 5 penetrates and extends to the top of the cap 4. A fixing sleeve 6 is fixedly connected to the central axis of the cap 4, and the fixing sleeve 6 is fitted onto the insert rod 5. On the outer wall, a sliding plate 8 is fixedly connected to the top of the insertion rod 5. Slide rails 7 are fixedly connected to both sides of the storage tank 1, and the sliding plate 8 slides inside the slide rails 7. The vegetable oil in the storage tank 1 supports the movable plate 18. Therefore, as the flow rate in the storage tank 1 decreases, the movable plate 18 will descend synchronously to ensure contact with the oil surface, thereby preventing the vegetable oil from contacting the air. This design effectively extends the storage period of the vegetable oil and ensures its quality. At the same time, since the movable plate 18 can always be in contact with the oil surface, it can prevent the vegetable oil inside from generating waves during movement, further slowing down the oxidation process of the vegetable oil and reducing the rate of oil rancidity, thereby reducing the generation of waste oil. It should be noted that a gap is provided between the insertion rod 5 and the fixed sleeve 6 to ensure that the movable plate 18 can move up and down.

[0022] A bottom plate 14 is fixedly connected to the movable plate 18, and a top plate 16 is fixedly connected to the bottom of the cover 4. A telescopic sleeve 15 is fixedly connected between the top plate 16 and the bottom plate 14. As the movable plate 18 slides downward, the bottom plate 14 gradually moves away from the top plate 16, and the telescopic sleeve 15 is stretched accordingly to occupy the space inside the storage tank 1, thereby further reducing the oxidation process of the vegetable oil.

[0023] A counterweight 17 is fixedly connected to the top of the movable plate 18. The counterweight 17 has a certain weight, which can press the movable plate 18. After the outlet 11 is opened, the efficiency of the vegetable oil in the storage tank 1 flowing out from the outlet 11 is improved under the pressure of the counterweight 17.

[0024] The inner side of the slide plate 8 is provided with uniformly distributed quantitative grooves 9, which facilitates the observation of changes in the oil volume in the storage tank 1.

[0025] Both ends of the slide plate 8 are fixedly connected to push-pull plates 10. By setting the push-pull plates 10, it is easy to manually adjust the height of the movable plate 18 in the storage tank 1 with appropriate height and force point.

[0026] An inlet pipe 3 is provided at the bottom of the side wall of the storage tank 1. When adding vegetable oil to the storage tank 1, the vegetable oil can be injected into the inlet pipe 3 so that it can enter the storage tank 1 from the bottom, thereby gradually lifting the movable plate 18.

[0027] Working principle:

[0028] The vegetable oil in storage tank 1 supports the movable plate 18. Therefore, as the flow rate in storage tank 1 decreases, the movable plate 18 will descend synchronously to ensure contact with the oil surface, thereby preventing the vegetable oil from contacting the air. This design effectively extends the shelf life of the vegetable oil and ensures its quality. At the same time, since the movable plate 18 can always be in contact with the oil surface, it can prevent the vegetable oil inside from generating waves during movement, further slowing down the oxidation process of the vegetable oil, reducing the rate of oil rancidity, and thus reducing the generation of waste oil.

[0029] As the movable plate 18 slides downward, the bottom plate 14 gradually moves away from the top plate 16, and the corresponding stretching sleeve 15 occupies the space inside the storage tank 1, thereby further reducing the oxidation process of the vegetable oil.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
