[0006] The above-mentioned objective of this application is achieved through the following technical solution:
[0007] A low-temperature constant-pressure storage device for vegetable oil includes a support, an insulated outer tank installed at the top center of the support, an inner storage tank installed inside the insulated outer tank, an inert gas storage tank installed at the top center of the insulated outer tank, a one-way inlet pipe installed at the inlet of the inert gas storage tank, and an adaptive pressure regulating component installed at the outlet of the bottom of the inert gas storage tank that communicates with the inner storage tank. The adaptive pressure regulating component includes an upper ring plate, an upper cover, a first spring, a guide frame, a linkage shaft, a second spring, a lower cover, and a lower ring plate.

[0010] Optionally, both the upper cover and the lower cover are composed of a circular plate with a sealing ring gasket on the periphery. Spring 1 is installed between the upper end of the guide frame and the upper cover, and spring 2 is installed between the bottom end of the guide frame and the lower cover. The linkage shaft passes through spring 1 and spring 2.
[0011] Optionally, a cooling mechanism is also installed between the insulated outer tank and the storage inner tank. The cooling mechanism includes a circulating cooling pipe, an inlet pipe, a return pipe, a circulating water pump, and a constant temperature cold water tank.

[0016] In summary, this application includes at least one of the following beneficial technical effects:
[0017] This invention involves installing an inert gas storage tank with a single-row inlet pipe at the top center of an insulated outer tank. An adaptive pressure regulating component, consisting of an upper ring plate, an upper cover, a first spring, a guide frame, a linkage shaft, a second spring, a lower cover, and a lower ring plate, is installed between the inert gas coarse storage tank and the inner storage tank. When pressure fluctuations occur in the inner storage tank due to temperature changes, the adaptive pressure regulating component connects the inert gas storage tank and the inner storage tank. This allows inert gas to flow from the inert gas storage tank into the inner storage tank when the pressure decreases, thus maintaining pressure stability. Conversely, when the pressure increases, gas flows from the inner storage tank into the inert gas storage pipe, ensuring pressure balance in the inner storage tank. Because the pressure balance in the inner storage tank is automatically adjusted by the adaptive pressure regulating component, the drawbacks of untimely manual adjustments are eliminated, resulting in more stable composition and better storage quality of the vegetable oil during storage.

[0024] The present application will be further described in detail below with reference to the accompanying drawings.
[0025] To better understand the technical solutions presented in the embodiments of this application, the structure and working principle of existing low-temperature constant-pressure storage devices for vegetable oils will be introduced first.
[0026] The existing low-temperature constant-pressure storage device for vegetable oil mainly consists of a low-temperature storage inner tank, a manually adjustable pressure stabilizing component installed on the low-temperature storage inner tank, a pressure gauge installed on the inner tank, and an oil inlet pipe and an oil outlet pipe installed on the inner tank. When storing vegetable oil at low temperature, the vegetable oil is directly added into the low-temperature storage inner tank, and the pressure inside the low-temperature storage inner tank is kept constant by the action of the manually adjustable pressure stabilizing component and the pressure gauge, thereby achieving low-temperature constant-pressure storage of vegetable oil.
[0027] Please see Figures 1-4 This application discloses a low-temperature constant-pressure storage device for vegetable oil, comprising a support 2, an insulated outer tank 1 installed at the top center of the support 2, an inner storage tank 3 installed inside the insulated outer tank 1, an inert gas storage tank 7 installed at the top center of the insulated outer tank 1, a one-way air inlet pipe 9 installed at the air inlet of the inert gas storage tank 7, and an adaptive pressure regulating component 8 installed at the air outlet of the bottom end of the inert gas storage tank 7 which communicates with the inner storage tank 3. The adaptive pressure regulating component 8 includes an upper ring plate 81, an upper cover 82, a first spring 83, a guide frame 84, a linkage shaft 85, a second spring 86, a lower cover 87, and a lower ring plate 88.
[0028] Specifically, during the storage of vegetable oil, inert gas needs to be pre-filled into the inert gas storage tank 7 through the one-way air inlet pipe 9 to ensure that the internal pressure of the inert gas storage tank 7 is balanced with the internal pressure of the inner storage tank 3. When the internal pressure of the inner storage tank 3 increases, the lower cover 87 will be lifted by the internal pressure of the inner storage tank 3, thereby opening the middle part of the lower ring plate 88. At the same time as the upper cover 82 opens, the linkage shaft 85 will drive the upper cover 82 to be lifted from the middle of the upper ring plate 81, smoothly opening the center part of the upper ring plate 81. When both the upper ring plate 81 and the lower ring plate 88 are open, the interior of the inert gas storage tank 7 is connected to the interior of the inner storage tank 3, so that the gas in the inner storage tank 3 can be supplied to the inert gas storage tank 7. The gas enters the storage tank 7 to maintain the stability of the gas pressure inside the inner storage tank 3. After the gas pressure inside the inner storage tank 3 stabilizes, the upper cover 82 and the lower cover 87 will be reset under the action of spring 1 83 and spring 2 86, respectively, thereby realizing the re-closure of the upper ring plate 81 and the lower ring plate 88. This achieves adaptive pressure adjustment when the gas pressure in the inner storage tank 3 increases. Similarly, when the gas pressure in the inner storage tank 3 decreases, the upper cover 82 and the lower cover 87 will move down simultaneously under the action of the pressure inside the inert gas storage tank 7, thereby realizing the connection between the inside of the inert gas storage tank 7 and the inner storage tank 3, so as to replenish the inert gas in the inert gas storage tank 7 to the inner storage tank 3, so as to ensure the stability of the pressure in the inner storage tank 3 again.
[0029] Please see Figures 1-4 The upper ring plate 81 is installed above the outlet of the inert gas storage tank 7, the lower ring plate 88 is installed below the outlet of the inert gas storage tank 7, and the guide frame 84 is installed inside the inert gas storage tank 7 between the upper ring plate 81 and the lower ring plate 88.
[0030] In one implementation, both the upper ring plate 81 and the lower ring plate 88 are ring-shaped plates, mainly used to seal the outlet of the inert gas storage tank 7.
[0031] Please see Figures 1-4 The guide frame 84 consists of a ring and four fixed rods installed around the ring. The linkage shaft 85 passes through the guide frame 84 and slides with the guide frame 84. The top end of the linkage shaft 85 is connected to the upper cover 82, and the bottom end of the linkage shaft 85 is connected to the lower cover 87.
[0032] As one implementation, the guide frame 84 can not only slide and guide the linkage shaft 85, but also provide a mounting base for spring 1 83 and spring 2 86 to ensure reliable installation and fixation of spring 1 83 and spring 2 86.
[0033] Please see Figures 1-4Both the upper cover 82 and the lower cover 87 are composed of a circular plate with a sealing ring gasket on the outside. Spring 1 83 is installed between the upper end of the guide frame 84 and the upper cover 82, and spring 2 86 is installed between the bottom end of the guide frame 84 and the lower cover 87. The linkage shaft 85 passes through spring 1 83 and spring 2 86.
[0034] As one implementation method, the upper cover 82 is inserted into the center of the upper ring plate 81 to block the center of the upper ring plate 81, and the lower cover 87 is inserted into the center of the lower ring plate 88 to block the center of the lower ring plate 88. This ensures that the inert gas storage tank 7 and the storage inner tank 3 are not connected when the gas pressure inside the storage inner tank 3 is stable.
[0035] Please see Figures 1-2 A cooling mechanism 5 is also installed between the outer insulated tank 1 and the inner storage tank 3. The cooling mechanism 5 includes a circulating cooling pipe 51, an inlet pipe 52, a return pipe 53, a circulating water pump 54, and a constant temperature cold water tank 55.
[0036] As one implementation method, the constant temperature cold water tank 55 is equipped with a temperature controller and a cooling component to ensure that the water temperature in the constant temperature cold water tank 55 can always be kept at a low temperature. The constant temperature cold water tank 55 is a mature product in the prior art, so it will not be described in detail here.
[0037] Please see Figures 1-2 The constant temperature cold water tank 55 is installed on one side wall of the support 2, the circulating water pump 54 is installed on one side of the top of the constant temperature cold water tank 55, the circulating cooling pipe 51 is installed in the interlayer between the heat preservation outer tank 1 and the storage inner tank 3 in a spiral winding manner, the water inlet pipe 52 is installed between the circulating cooling pipe 51 and the water outlet of the circulating water pump 54, and the water return pipe 53 is installed between the circulating cooling pipe 51 and the constant temperature cold water tank 55.
[0038] In one implementation, the circulating water pump 54 introduces the low-temperature water in the constant temperature cold water tank 55 into the circulating cooling pipe 51 through the inlet pipe 52. This ensures the low-temperature storage of the vegetable oil in the storage tank 3 when the low-temperature water flows through the circulating cooling pipe 51. The cooled water will eventually enter the constant temperature cold water tank 55 through the return water pipe 53 for reuse.
[0039] Please see Figure 1 , Figure 2 and Figure 5 The inner storage tank 3 is equipped with a filter cleaning assembly 4 at its discharge pipe. The filter cleaning assembly 4 includes a filter box 41, a waste box 42, a baffle 43, a connecting rod 44, a filter screen 45, a scraper 46, and an electric telescopic rod 47.
[0040] As one implementation method, when vegetable oil is taken from the storage tank 3, the filter screen 45 filters out the tiny impurities present in the vegetable oil, ensuring the quality of the vegetable oil during storage.
[0041] Please see Figure 1 , Figure 2 and Figure 5 The filter box 41 is installed in the middle of the discharge pipe of the storage tank 3. The filter screen 45 is installed in the middle of the filter box 41. The electric telescopic rod 47 is installed on one side wall of the filter box 41. The scraper 46 is installed on the telescopic part of the electric telescopic rod 47. The connecting rod 44 is installed on the side of the scraper 46 opposite to the electric telescopic rod 47. The baffle 43 is connected to the end of the connecting rod 44 opposite to the scraper 46. The waste box 42 is installed on the side wall of the filter box 41 opposite to the electric telescopic rod 47 by a hook.
[0042] As one implementation method, after the vegetable oil in the storage tank 3 has been used for a period of time, there will be a lot of impurities on the filter screen 45. At this time, under the action of the electric telescopic rod 47, the scraper 46, the connecting rod 44 and the baffle 43 will move synchronously, which can scrape the impurities on the filter screen 45 into the waste box 42, so as to realize the centralized cleaning and collection of waste.
[0043] Please see Figures 1-2 A sealing cap 6 is also installed at the feed inlet at the top of the insulated outer tank 1.
[0044] As one implementation method, the sealing cap 6 is mainly used to ensure the sealing performance of the filling port on the inner storage tank 3, so as to reduce the entry of external air into the inner storage tank 3 during the storage of vegetable oil.
[0045] The specific working principle is as follows: First, the vegetable oil to be stored is added to the inner storage tank 3, and the sealing cap 6 is tightened. Simultaneously, the cooling mechanism 5 keeps the inner storage tank 3 at a low temperature, thus achieving low-temperature storage of the vegetable oil. During the storage process, inert gas needs to be pre-filled into the inert gas storage tank 7 through the one-way air inlet pipe 9 to ensure that the internal pressure of the inert gas storage tank 7 is balanced with that of the inner storage tank 3. When the internal pressure of the inner storage tank 3 increases, the lower cover 87 is lifted by the internal pressure, thus opening the middle part of the lower ring plate 88. Simultaneously, the upper cover 82 opens, and the linkage shaft 85 lifts it from the middle of the upper ring plate 81, smoothly opening the center part of the upper ring plate 81. With both the upper and lower ring plates 81 open, the interior of the inert gas storage tank 7 is connected to the interior of the inner storage tank 3, allowing gas from the inner storage tank 3 to be transferred to the inert gas storage tank. The gas enters the inner storage tank 7 to maintain stable internal pressure in the inner storage tank 3. Once the internal pressure in the inner storage tank 3 stabilizes, the upper cover 82 and lower cover 87 will reset under the action of spring 1 83 and spring 2 86, respectively, thereby reclosing the upper ring plate 81 and lower ring plate 88. This achieves adaptive pressure adjustment when the internal pressure in the inner storage tank 3 increases. Similarly, when the internal pressure in the inner storage tank 3 decreases, the upper cover 82 and lower cover 87 will move down simultaneously under the pressure inside the inert gas storage tank 7, thus connecting the inner storage tank 7 with the inner storage tank 3. This allows inert gas from the inert gas storage tank 7 to be replenished into the inner storage tank 3, ensuring stable pressure again. Because the pressure balance in the inner storage tank 3 is automatically adjusted under the action of the adaptive pressure regulating component 8, there is no drawback of untimely manual adjustment, resulting in more stable composition and better storage quality of the vegetable oil during storage.
[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
