[0026] Please refer to Figures 1-4 , the present invention provides a technical solution for a CO2 intermediate storage tank for lycopene production: a CO2 intermediate storage tank for lycopene production, including a storage tank 1, one input end of the storage tank 1 is fixedly connected with a feed pipe 4, one output end of the storage tank 1 is fixedly connected with a discharge pipe 5, a sealing mechanism 6 is arranged on the outer and inner sides of the feed pipe 4, and the sealing mechanism 6 is used to prevent oxygen in the air from entering the interior of the storage tank 1 when injecting lycopene.

[0027] The sealing mechanism 6 includes an airbag assembly, an air extraction assembly and a valve assembly;

[0028] The airbag assembly is used to improve the sealing performance of the input end of the feed pipe 4;

[0029] The air extraction assembly is used to extract the air inside the feed pipe 4 to the outside;

[0031] Please pay special attention to Figure 1 , the other input end of the storage tank 1 is fixedly connected with a CO2 inlet pipe 2, and the other output end of the storage tank 1 is fixedly connected with a CO2 exhaust pipe 3.

[0032] In this embodiment: when the storage tank 1 needs to be used, CO2 is input into the storage tank 1 through the CO2 inlet pipe 2, and when the use of the storage tank 1 is completed, the CO2 is discharged to the outside through the CO2 exhaust pipe 3.

[0033] Please pay special attention to Figure 3 , the airbag assembly includes a first air pump 601, a first connecting pipe 604 and an airbag 605;

[0034] The first air pump 601 is fixedly installed on the surface of the feed pipe 4. The first connecting pipe 604 is fixedly connected to the output end of the first air pump 601. The airbag 605 is arranged inside the input end of the feed pipe 4, and the docking end of the first connecting pipe 604 is communicated with the airbag 605.

[0035] In this embodiment: By inserting the material conveying pipe into the feed pipe 4, aligning the material conveying pipe with the input end of the docking pipe 606. At this time, the first air pump 601 is powered on and operated, so that the first air pump 601 in the powered-on state drives the airbag 605 to operate. The first air pump 601 conveys gas into the airbag 605 through the first connecting pipe 604. The airbag 605 expands due to the gas, and the expanded airbag 605 closely fits the surface of the material conveying pipe, thereby improving the sealing performance of the input end of the feed pipe 4.

[0036] Please refer specifically to Figure 3 , the first air pump 601 in the powered-on state is used to drive the airbag 605 to operate, and the expanded airbag 605 is used to improve the sealing performance of the input end of the feed pipe 4.

[0037] In this embodiment: The first air pump 601 is powered on and operated, so that the first air pump 601 in the powered-on state drives the airbag 605 to operate. The first air pump 601 conveys gas into the airbag 605 through the first connecting pipe 604. The airbag 605 expands due to the gas, and the expanded airbag 605 closely fits the surface of the material conveying pipe.

[0038] Please refer specifically to Figure 3 , the air extraction assembly includes a second air pump 602, a docking pipe 606, a second connecting pipe 607 and an oxygen sensor 608;

[0039] The second air pump 602 is fixedly installed on the surface of the feed pipe 4. The docking pipe 606 is fixedly connected to the inner wall of the feed pipe 4. The second connecting pipe 607 is fixedly connected to the docking end of the second air pump 602, and the docking end of the second connecting pipe 607 is communicated with the docking end of the docking pipe 606. The oxygen sensor 608 is fixedly installed on the inner wall of the docking pipe 606.

[0040] In this embodiment: By powering on and operating the second air pump 602, the operating second air pump 602 extracts the air inside the docking pipe 606 through the second connecting pipe 607, and extracts the excess air inside the docking pipe 606 to the outside. Since the oxygen sensor 608 is electrically connected to the second air pump 602 and the shaft holding motor 603, the receiving end of the operating oxygen sensor 608 detects that there is no excess air inside the docking pipe 606, and the transmitting end of the oxygen sensor 608 transmits a signal to the controller, and the controller then controls the shaft holding motor 603 to be powered on and operate.

[0041] Please refer specifically to Figure 4, the valve assembly includes a shaft-holding motor 603 and a spherical valve 609;

[0042] The shaft-holding motor 603 is fixedly installed on the surface of the feed pipe 4, the spherical valve 609 is rotatably installed inside the output end of the feed pipe 4, and the spherical valve 609 is fixedly connected to the end of the output shaft of the shaft-holding motor 603.

[0043] In this embodiment: The shaft-holding motor 603 is controlled by the controller to be powered on and operate. The output shaft of the shaft-holding motor 603 in the operating state drives the spherical valve 609 to rotate clockwise by ninety degrees. Then, the spherical valve 609 in the clockwise ninety-degree rotation state will open the output end of the docking pipe 606 (it should be noted that the spherical valve 609 in the counterclockwise ten-degree rotation state will close the output end of the docking pipe 606. Then, when lycopene has not been filled, the output end of the docking pipe 606 remains closed).

[0044] Please refer specifically to Figure 4 , the positions of the first air pump 601, the second air pump 602, and the shaft-holding motor 603 are arranged from left to right in sequence, and the oxygen sensor 608 is electrically connected to the second air pump 602 and the shaft-holding motor 603.

[0045] In this embodiment: Since the oxygen sensor 608 is electrically connected to the second air pump 602 and the shaft-holding motor 603, the receiving end of the oxygen sensor 608 in the operating state detects that there is no excess air inside the docking pipe 606, and the transmitting end of the oxygen sensor 608 transmits a signal to the controller, and the controller then controls the shaft-holding motor 603 to be powered on and operate.

[0046] Working principle: When it is necessary to fill lycopene into the storage tank 1 for storage, first input CO2 into the storage tank 1 through the CO2 inlet pipe 2, then insert the feeding pipe into the feeding pipe 4 so that the feeding pipe is aligned with the input end of the docking pipe 606. At this time, connect the first air pump 601 to power and run it, so that the energized first air pump 601 drives the airbag 605 to operate. The first air pump 601 transports gas into the airbag 605 through the first connecting pipe 604. The airbag 605 expands due to the gas, and the expanded airbag 605 closely fits the surface of the feeding pipe, thereby improving the sealing performance of the input end of the feeding pipe 4. At this time, connect the second air pump 602 to power and run it, so that the operating second air pump 602 evacuates the inside of the docking pipe 606 through the second connecting pipe 607, and extracts the excess air inside the docking pipe 606 to the outside. Since the oxygen sensor 608 is electrically connected to the second air pump 602 and the shaft holding motor 603, the receiving end of the operating oxygen sensor 608 detects that there is no excess air inside the docking pipe 606, and the transmitting end of the oxygen sensor 608 transmits a signal to the controller. The controller then controls the shaft holding motor 603 to be powered on and run. The output shaft of the operating shaft holding motor 603 drives the spherical valve 609 to rotate clockwise by 90 degrees. Then, the spherical valve 609 in the clockwise 90-degree rotation state opens the output end of the docking pipe 606 (it should be noted that the spherical valve 609 in the counterclockwise 10-degree rotation state closes the output end of the docking pipe 606. When the lycopene has not been filled, the output end of the docking pipe 606 remains closed). Then, the lycopene is filled into the storage tank 1 through the feeding pipe 4 and the open docking pipe 606 for storage. Through the above structure, the situation that oxygen in the air enters the inside of the storage tank 1 during the lycopene injection is effectively prevented.
