[0002] Rapeseed oil is a common edible oil containing a large amount of unsaturated fatty acids. These unsaturated fatty acids are easily oxidized by oxygen in the air during storage. Oxidation can cause rapeseed oil to develop an off-flavor, become rancid, reduce its nutritional value, and even produce substances that are harmful to the human body.

[0003] In existing rapeseed oil storage processes, air replenishment and venting are usually performed during oil filling or extraction. When replenishing air, the air replenishment valve is opened directly, allowing outside air to enter the tank directly. The moisture, impurities, and bacteria in the air directly enter the rapeseed oil, thus contaminating it and making it unhygienic. Therefore, we need to propose a sealed rapeseed oil storage tank.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a sealed rapeseed oil storage tank, including a push plate 1 and a tank body 2. A pulley is installed under the push plate 1 to facilitate flexible movement of the tank body 2. The tank body 2 is installed on the top of the push plate 1. An oil injection assembly is installed on the top of the tank body 2. The oil injection assembly includes an oil injection pipe 3. One end of the oil injection pipe 3 is connected to the top of the tank body 2 to facilitate the delivery of rapeseed oil. A first one-way valve 4 is installed on the oil injection pipe 3 to prevent the rapeseed oil inside the tank body 2 from flowing back.

[0025] A gas storage tank 6 is installed on the top of the tank body 2. The gas storage tank 6 is used to store argon gas, which is an inert gas. When argon gas is filled into the rapeseed oil storage tank, it will form a protective gas layer on the surface of the oil, effectively isolating oxygen from contact with the rapeseed oil. A gas replenishment component for replenishing argon gas to the tank body 2 is installed on the outside of the gas storage tank 6. One end of the gas replenishment component extends into the interior of the tank body 2. The gas replenishment component includes a first gas inlet pipe 5. One end of the first gas inlet pipe 5 is connected to the exhaust end of the gas storage tank 6, and the other end of the first gas inlet pipe 5 is connected to the top of the tank body 2. By setting the first gas inlet pipe 5, argon gas is supplied to the rapeseed oil inside the tank body 2. A first valve 7 is installed on the first gas inlet pipe 5, which can control the opening and closing of the first gas inlet pipe 5.

[0026] Furthermore, an exhaust assembly is installed on the outside of the tank body 2 to discharge excess gas from inside the tank body 2. The exhaust assembly includes a first exhaust pipe 8, which is used to transport excess argon gas inside the tank body 2. One end of the first exhaust pipe 8 is connected to an oil mist filter 9, and the end of the oil mist filter 9 away from the first exhaust pipe 8 is connected to the top of the tank body 2. By setting the oil mist filter 9, the fine oil mist that may be carried in the argon gas discharged from inside the tank body 2 due to volatilization can be filtered out by the oil mist filter 9, which can also reduce the odor produced by rapeseed oil inside the tank body 2. A second valve 10 is installed on the first exhaust pipe 8, which can control the opening and closing of the first exhaust pipe 8.

[0027] Furthermore, one end of the exhaust assembly is connected to a filter assembly for argon gas filtration. The filter assembly includes a filter box 11 and an air pump 12. By setting the filter box 11, the space sealing during argon gas filtration can be ensured. The air pump 12 is installed on the top of the push plate 1. The other end of the first exhaust pipe 8 is connected to the air inlet of the air pump 12, and the exhaust end of the air pump 12 is connected to one end of the filter box 11. A filter plate 13 is set inside the filter box 11. By setting the air pump 12, power can be provided to the first exhaust pipe 8 to deliver argon gas into the filter box 11. The filter plate 13 is filled with activated carbon and polytetrafluoroethylene (PTFE) filter elements, which can not only adsorb and remove organic matter and other pollutants in the argon gas. It removes impurities such as odor and has antibacterial and microbial growth-inhibiting functions, which can effectively improve the purity of argon. The end of the filter component away from the exhaust component is connected to a recovery component for recovering the purified argon. The recovery component includes a second exhaust pipe 14. The end of the filter box 11 away from the gas pump 12 is connected to one end of the second exhaust pipe 14. The end of the second exhaust pipe 14 away from the filter box 11 is connected to the air inlet of the gas storage tank 6. A third valve 15 is installed on the second exhaust pipe 14. One end of the recovery component is connected to the air inlet of the gas storage tank 6. The second exhaust pipe 14 is used to transport the filtered argon. The third valve 15 can control the opening and closing of the second exhaust pipe 14.

[0028] It is worth noting that an oil outlet pipe 16 is connected to the outer side of the tank body 2, and a fourth valve 17 is installed on the oil outlet pipe 16. The opening and closing of the oil outlet pipe 16 can be controlled by setting the fourth valve 17. A first pressure detector 18 is installed on the top of the tank body 2. The interior of the tank body 2 can be monitored in real time by setting the first pressure detector 18. A second pressure detector 19 is installed on the top of the gas storage tank 6. The interior of the gas storage tank 6 can be monitored in real time by setting the second pressure detector 19.

[0029] When rapeseed oil needs to be injected into tank 2, it is injected through the oil injection pipe 3. If the pressure of the first pressure detector 18 is lower than the normal value, gas replenishment is required. The first valve 7 is opened to deliver argon gas from the gas storage tank 6 to the inside of tank 2 through the first air inlet pipe 5. When the pressure value of the first pressure detector 18 reaches the normal value, the first valve 7 is closed to end the gas replenishment. If the value of the first pressure detector 18 is higher than the standard value, venting is required. The first valve 7 is closed, the second valve 10 is opened, and the air pump 12 is started. Excess gas inside tank 2 first passes through the oil mist filter 9 to pre-filter the fine oil mist it carries, and then... The argon gas is delivered to the filter box 11 through the first exhaust pipe 8. When passing through the filter plate 13 inside the filter box 11, the activated carbon and polytetrafluoroethylene (PTFE) filter element inside the filter plate 13 filter and sterilize the impurities such as moisture and oxygen contained in the exhaust gas. After the exhaust is completed, the second valve 10 is closed and the third valve 15 is opened. The filtered pure argon gas returns to the gas storage tank 6 for recycling through the second exhaust pipe 14. When the second pressure detector 19 installed on the top of the gas storage tank 6 is lower than the normal value, the third valve 15 is closed and the gas storage tank 6 is replenished with gas through the gas inlet. When oil needs to be taken, the fourth valve 17 is opened to take oil.

[0030] In summary, by supplementing tank 2 with argon gas in a sealed manner, moisture, impurities, and bacteria in the air can be prevented from entering tank 2 and contaminating the rapeseed oil. The argon gas emission and recovery components, together with the filtration components, circulate the argon gas to remove moisture, impurities, and bacteria contained in the discharged argon gas, preventing them from entering tank 2 and coming into contact with the rapeseed oil to contaminate it.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
